Skin Metastases \u0026 Mimics: Rapid Board Review for Dermatology Pathology Dermpath (18 Classic Cases)

Intake of noncaffeinated liquids should be encouraged: 2 quarts per day of juices or other caloric beverages in frequent, small amounts rather than water alone. Elimination is maintained by administering stool softeners as necessary if analgesic drugs result in constipation. Using careful and gentle handling, the health care professional assists with range-of-motion exercises, encourages ambulation and mobility, and turns and repositions the immobile patient frequently to decrease the deleterious multisystemic effects of immobilization.

The patient is made comfortable by correct body alignment, noninvasive measures such as guided imagery and cutaneous stimulation , and medication preferably administered on a regular schedule to prevent pain, with additional dosing to relieve breakthrough pain. Emotional assistance includes allaying the patient's fears of helplessness and loss of control; providing hope for remission or long-term survival but avoiding giving false hope; and providing the patient with realistic reassurance about pain control, comfort, and rest.

Psychological counseling and antidepressant therapies may be helpful. Hospice care at home or in a dedicated center , if needed, is discussed with the patient and family. The goal is to provide good quality of life with minimal discomfort, pain, and restrictions rather than to continue specific therapy. Family members are encouraged to assume an active role in caring for the patient. Communication is fostered between patient and family and other health care providers, and the patient is helped to maintain control and to carry out realistic decisions about issues of life and death.

To provide effective emotional support to the patient and family, health care professionals must understand and cope with their own feelings about terminal illness and death and seek assistance with grieving and in developing a personal philosophy about dying and death. They will then be better able to listen sensitively to patients' concerns, to offer genuine understanding and comfort, and to help patients and family work through their grief. Some strains of the human papillomavirus HPV are carcinogenic to cervical epithelium. While there are other risk factors such as tobacco smoking, early age at first intercourse, and having multiple sex partners , HPV is the major factor responsible for the development of this cancer. Periodic Pap tests are recommended for all sexually active women.

Dilatation and curettage, punch biopsy, and colposcopy may be done if Pap test findings raise the suspicion of cancer. If abnormal cells are detected, HPV testing is often performed to screen for presence of one of the high risk types of the virus. See: Bethesda System, The ; cervical intraepithelial neoplasia ; colposcopy ; cryosurgery ; loop electrode excision procedure ; Papanicolaou test. Management varies from cryotherapy or laser therapy for low-grade squamous intraepithelial lesions, conization for carcinoma in situ, to hysterectomy for preinvasive cervical cancer in women who are not planning to have children.

The cancer occurs more often in people with a family history of the disease, those with familial adenomatous polyposis, and in those with inflammatory bowel diseases such as ulcerative colitis. It also occurs more often in people who are obese than in those who are not and in those who consume a high fat, low-fiber diet. Symptoms may be absent or may include change in the usual pattern of bowel habits, esp. Laboratory findings may include iron-deficiency anemia or positive fecal occult blood tests.

Diagnosis may be suggested by findings on digital rectal examination, anoscopy, flexible or rigid sigmoidoscopy, colonoscopy, virtual colonoscopy, or barium enema examination. It is confirmed by biopsy of suspicious lesions. Prevention includes screening of asymptomatic men and women of average risk starting at age 50, annual home fecal occult blood testing over a three-day period , and colonoscopy every 10 years. During colonoscopy, removal of benign polyps prevents progression to malignant tumors. If polyps are found, colonoscopy should be repeated in 3 to 5 years depending on the presence of other risk factors.

Detection of colorectal cancer at an early stage via colonoscopy offers patients a very high likelihood of cure rate at 5 years. Neither digital rectal examination nor testing of a single stool specimen from the digital exam provides adequate screening. Patients at increased risk for colorectal cancer those who have had previous colorectal adenomas or resected cancers or a history of ulcerative colitis or of colon cancer in a first-degree relative younger than 60 should undergo screening more frequently and at an earlier age. When colorectal carcinoma is diagnosed, additional tests are conducted to determine the stage of the disease chest radiographs, CT, MRI, and blood studies, including carcinoembryonic antigen levels, and liver function studies.

Surgical resection performed by laparotomy, minimally invasive surgery, microsurgery, or laparoscopy can cure localized colorectal cancer. Whatever procedure is used, the type of surgery depends on the location of the tumor, and the goal of the surgery is removal of the malignant tumor and adjacent tissue and any lymph nodes that may contain cancer cells. Adjuvant therapies may include chemoembolization of blood vessels that feed the primary tumor or metastases; radiation therapy; brachytherapy; chemotherapy; or monoclonal antibody therapy. Carcinoembryonic antigen is helpful in monitoring patients during and following treatment to determine effectiveness and detect recurrence or metasasis.

Health care providers should teach patients the importance of colorectal screening and indicate applicable lifestyle modifications a low-fat diet, maintenance of a normal body mass index. Patients with familial colon cancer syndromes, such as familial adenomatous polyposis, should be counseled about the need for close surveillance by professional gastroenterologists. Aspirin and other nonsteroidal anti-inflammatory drugs appear to reduce the number of colon polyps, thus decreasing the risk of developing colorectal cancer. Patients interested in such therapy should discuss its potential risks and benefits with their health care providers.

Patients diagnosed with colorectal cancer who undergo surgery need counseling about the operation, the duration of recovery, and, in many cases, the use of a postoperative colostomy. Before surgery, a stomal therapist consults with the surgeon regarding appropriate stoma location, and the abdomen is marked. The therapist answers questions from the patient and family and begins to develop a relationship that will support the patient through postoperative care and teaching.

From to the s, the incidence of gastric cancer declined from about 38 cases per , to about 6 cases per , In , the ACS estimated there would be 21, new cases of gastric cancer in the U. Although the cause of gastric cancer is unknown, predisposing factors include a diet rich in pickled or smoked foods, a history of gastric surgery, and a history of infection by Helicobacter pylori. The disease runs in some families; therefore, there may also be a genetic component. Malnutrition occurs as a result of impaired eating, the metabolic demands of the growing tumor, or obstruction of the GI tract.

Iron deficiency anemia results as the tumor causes ulceration and bleeding. The tumor can interfere with the production of the intrinsic factor needed for vitamin B 12 absorption, resulting in pernicious anemia. As the cancer spreads to regional lymph nodes and nearby structures and metastasizes to other structures, related complications occur. In the early stages, the patient may occasionally experience pain in the back or in the epigastric or retrosternal areas that is relieved with nonprescription analgesics. As the tumor grows, the patient may notice a vague feeling of fullness, heaviness, and abdominal distention after meals.

Depending on the progression of the cancer, the patient may report weight loss due to disturbance of the appetite; nausea; and vomiting. There may be dysphagia and coffee-ground vomitus if the tumor is located in the cardia and slowly bleeds. Weakness and fatigue are common. Because early symptoms include chronic dyspepsia and epigastric discomfort, patients may self-treat with OTC antacids or histamine blockers, delaying prescribed therapies and allowing the cancer to progress. Palpation of the abdomen may disclose a mass. A skilled examiner may be able to palpate enlarged lymph nodes, esp. Gastric cancer is diagnosed by fiber-optic endoscopy with biopsy. Studies to rule out specific organ metastases include endoscopic ultrasonography, computed tomography scans, chest radiographs, liver and bone scans, and liver biopsy.

Radical surgery to remove the tumor is possible in more than one third of patients. The nature and extent of the lesion determine the type of surgery. Surgical procedures include gastroduodenostomy, gastrojejunostomy, partial gastric resection, and total gastrectomy. If metastasis has occurred, the omentum and spleen may have to be removed. Chemotherapy for GI tumors may help control signs and symptoms and prolong survival. Gastric adenocarcinomas respond to several agents, including fluorouracil, carmustine, doxorubicin, and mitomycin.

Tumors that express HER2 antigens respond to treatment with trastuzumab a monoclonal antibody that targets the human epidermal growth factor. Antispasmodics, antacids, and proton pump inhibitors may help relieve GI acidity and reflux symptoms. Antiemetics can control nausea, which intensifies as the tumor grows. Analgesics, sedatives, and tranquilizers are used to control pain and anxiety. Nutritional intake is monitored, and the patient is weighed periodically.

The health care provider initiates comprehensive clinical and laboratory investigations, including serial studies as indicated, if these have not already been done. The patient is prepared physically and emotionally for surgery, chemotherapy, or radiotherapy. During hospitalization, all general patient care concerns apply. Throughout the course of the illness, a high-protein, high-calorie diet with vitamin supplementation helps the patient avoid or recover from weight loss, malnutrition, and anemia, and promote wound healing.

Frequent small meals are offered. To stimulate a poor appetite, antidepressant or steroid drugs may be administered. The patient is instructed in use of all drugs and the expected adverse effects of treatment, as well as in management strategies for these effects. Radiation therapy may cause nausea, vomiting, local skin damage, malaise, diarrhea, and fatigue. Chemotherapy may cause bone marrow suppression, infection, nausea, vomiting, mouth ulcers, and hair loss. During radiation or chemotherapy, oral intake is encouraged to remove toxic metabolites. Bland fruit juices, ginger ale, or other fluids, and prescribed antiemetics are provided to minimize nausea and vomiting; comfort and reassurance are offered as needed.

The patient is advised to report persistent adverse reactions. The patient is encouraged to follow a normal routine as much as possible after recovery from surgery and during radiation therapy and chemotherapy. He should stop activities that cause excessive fatigue at least temporarily and incorporate rest periods. The patient should avoid crowds and people with known infections.

Home-health care is provided as necessary. If curative treatment fails, palliative care and psychological support continues, with questions answered honestly but tactfully. Home or in-patient hospice care referrals are suggested as available. The disease may cause severe pain and tenderness; cachexia loss of weight ; and encephalopathy. Jaundice is common. The liver is enlarged, its surface is nodular, and a central depression or umbilications can often be detected. Staging determines the extent of the disease and aids in planning treatment and predicting the prognosis.

Lung cancer is relatively difficult to cure but much easier to prevent. Children and adolescents should be discouraged from smoking tobacco products, and current smokers should be assisted in their efforts to quit, e. Chest x-rays do not show small, early cancers, but CT scanning can be used to screen people who have a long history of smoking and who are 50 to 60 years old. In this high-risk group, screening detects the disease in its early stages when it is most likely to be curable. However, since screening is very expensive, and since there are millions of smokers, the public health costs of mass screening are high compared with the cost of encouraging smokers to quit or of teaching teenagers not to start smoking.

Currently, more women die of epithelial ovarian cancer than of all other gynecological cancers combined. A small percentage of patients with ovarian cancer may have a hereditary predisposition, e. High-risk women include those with multiple first-degree relatives mother, sister, daughter or second-degree relatives aunt, grandmother, cousin with histories of breast or ovarian cancer.

Preventive surgery to remove the ovaries and fallopian tubes is the only way such women can significantly reduce their risk. Ovarian cancer patients may feel threatened or vulnerable. They benefit from pretreatment support and education. Health care professionals address the patient's psychosocial needs while preparing her for treatment and manage the potential adverse reactions and the treatment and changes related to advancing disease. The first step in care is typically surgical debulking of the tumor. In this phase of care, the surgical oncologist attempts to remove not only the primary tumor, but also as many small tumorlets found within the peritoneum. The patient and family should be taught about the extensive surgical procedure and what to expect after surgery.

After surgery, the patient is monitored for infection, circulatory complications, fluid and electrolyte imbalances, and pain. The patient who is to receive chemotherapy should be taught about major adverse reactions to the usual medications employed, taxanes and platinum-based drugs, such as fatigue, nausea and vomiting, hair loss, diarrhea, constipation, mucositis, neuropathy, arthralgia and myalgia, difficulty concentrating chemobrain , and myelosuppression, as well as about measures to be taken to prevent and manage these problems.

Chemotherapy may be given directly into the peritoneum or intravenously. Depression, anger, frustration, and anxiety are common. After the acute phase of treatment, the patient may undergo premature menopause; loss of fertility; alterations in body image, sexual function, and family relationships; impaired functional capacity; financial difficulties; and loss of spiritual well-being. The patient should be assessed for mood changes, inability to concentrate, fatigue, insomnia, and other symptoms of depression.

Her medical history, current medications and treatments, nutritional status, pain rating, elimination pattern, and sexual history should be reviewed for factors that contribute to depression. Participating in a support group, meeting with mental health professionals, and taking an antidepressant or anti-anxiety medication can help alleviate depression and anxiety. Advancing or relapsing ovarian cancer may cause complications. These may include development of ascites, intestinal obstruction, deep vein thrombosis, malnutrition and cachexia, lymphedema, and pleural effusion. If ovarian cancer recurs after treatment or fails to regress with treatment, palliative and end-of-life care may aid both patients and their families.

According to the U. Patients with such cancers are usually evaluated for tumors that might respond well to therapy, such as a lymphoma, a thyroid cancer, a germ cell tumor, or neoplasms of the breast or prostate. Generally, vulvar cancers are localized, slow-growing, and marked by late metastasis to the regional lymph nodes. See: vulvectomy. Radiation, surgery and chemotherapy are all used in the treatment of cancers.

There are over different types of cancer. You can develop cancer in any body organ. There are over 60 different organs in the body where you can get a cancer. Each organ is made up of several different tissue types. For example, there is usually a surface covering of skin or epithelial tissue. Underneath that there will be some connective tissue, often containing gland cells. Underneath that there is often a layer of muscle tissue and so on.

Each type of tissue is made up of specific types of cells. Cancer can develop in just about any type of cell in the body. So there is almost always more than one type of cancer that can develop in any one organ. Hippocrates first called it in that name after describing few types of cancer. Cancer - incurable? Is there not a medicine found yet? Really is it incurable? I like to share with you what i read from a book it said 'With modern day treatments many cancers are completely cured but unfortunately there are still many others which are not. Although it is not always possible to be certain, doctors are often able to tell whether or not a particular cancer might be cured.

Even if cancer is incurable they will usually still offer treatment in the hope of prolonging life and, controlling, symptoms. Related to cancer: lung cancer , Cancer treatment. Cancer Definition Cancer is not just one disease, but a large group of almost diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites.

If the spread is not controlled, cancer can result in death. One out of every four deaths in the United States is from cancer. It is second only to heart disease as a cause of death in the states. About 1. Cancer can attack anyone. Since the occurrence of cancer increases as individuals age, most of the cases are seen in adults, middle-aged or older. Sixty percent of all cancers are diagnosed in people who are older than 65 years of age. The most common cancers are skin cancer, lung cancer, colon cancer , breast cancer in women , and prostate cancer in men.

In addition, cancer of the kidneys, ovaries, uterus, pancreas, bladder, rectum, and blood and lymph node cancer leukemias and lymphomas are also included among the 12 major cancers that affect most Americans. Cancer, by definition, is a disease of the genes. A gene is a small part of DNA, which is the master molecule of the cell. Genes make "proteins," which are the ultimate workhorses of the cells. It is these proteins that allow our bodies to carry out all the many processes that permit us to breathe, think, move, etc.

Throughout people's lives, the cells in their bodies are growing, dividing, and replacing themselves. Many genes produce proteins that are involved in controlling the processes of cell growth and division. An alteration mutation to the DNA molecule can disrupt the genes and produce faulty proteins. This causes the cell to become abnormal and lose its restraints on growth. The abnormal cell begins to divide uncontrollably and eventually forms a new growth known as a "tumor" or neoplasm medical term for cancer meaning "new growth". In a healthy individual, the immune system can recognize the neoplastic cells and destroy them before they get a chance to divide.

However, some mutant cells may escape immune detection and survive to become tumors or cancers. Tumors are of two types, benign or malignant. A benign tumor is not considered cancer. It is slow growing, does not spread or invade surrounding tissue, and once it is removed, doesn't usually recur. A malignant tumor, on the other hand, is cancer. It invades surrounding tissue and spreads to other parts of the body.

If the cancer cells have spread to the surrounding tissues, even after the malignant tumor is removed, it generally recurs. A majority of cancers are caused by changes in the cell's DNA because of damage due to the environment. Environmental factors that are responsible for causing the initial mutation in the DNA are called carcinogens, and there are many types. There are some cancers that have a genetic basis. In other words, an individual could inherit faulty DNA from his parents, which could predispose him to getting cancer.

Cancers that are known to have a hereditary link are breast cancer, colon cancer, ovarian cancer , and uterine cancer. Besides genes, certain physiological traits could be inherited and could contribute to cancers. For example, inheriting fair skin makes a person more likely to develop skin cancer, but only if he or she also has prolonged exposure to intensive sunlight. Carcinomas are cancers that arise in the epithelium the layer of cells covering the body's surface and lining the internal organs and various glands. Ninety percent of human cancers fall into this category. Carcinomas can be subdivided into two types: adenocarcinomas and squamous cell carcinomas.

Adenocarcinomas are cancers that develop in an organ or a gland, while squamous cell carcinomas refer to cancers that originate in the skin. Melanomas also originate in the skin, usually in the pigment cells melanocytes. Sarcomas are cancers of the supporting tissues of the body, such as bone, muscle and blood vessels. Cancers of the blood and lymph glands are called leukemias and lymphomas respectively. Gliomas are cancers of the nerve tissue. The major risk factors for cancer are: tobacco, alcohol, diet, sexual and reproductive behavior, infectious agents, family history, occupation, environment and pollution.

An additional one-third of the deaths were related to diet and nutrition. Many of the one million skin cancers diagnosed in were due to over-exposure to ultraviolet light from the sun's rays. Smoking has also been shown to be a contributory factor in cancers of upper respiratory tract, esophagus, larynx, bladder, pancreas, and probably liver, stomach, breast, and kidney as well. Recently, scientists have also shown that second-hand smoke or passive smoking can increase one's risk of developing cancer.

Excessive consumption of alcohol is a risk factor in certain cancers, such as liver cancer. Alcohol, in combination with tobacco, significantly increases the chances that an individual will develop mouth, pharynx, larynx, and esophageal cancers. Thirty-five percent of all cancers are due to dietary causes. Excessive intake of fat leading to obesity has been associated with cancers of the breast, colon, rectum, pancreas, prostate, gall bladder, ovaries, and uterus.

The human papillomavirus, which is sexually transmitted, has been shown to cause cancer of the cervix. Having too many sex partners and becoming sexually active early has been shown to increase one's chances of contracting this disease. In addition, it has also been shown that women who don't have children or have children late in life have an increased risk for both ovarian and breast cancer. The most common cancer-causing pathogens and the cancers associated with them are shown in table form.

Certain cancers like breast, colon, ovarian, and uterine cancer recur generation after generation in some families. A few cancers, such as the eye cancer "retinoblastoma," a type of colon cancer, and a type of breast cancer known as "early-onset breast cancer," have been shown to be linked to certain genes that can be tracked within a family. It is therefore possible that inheriting particular genes makes a person susceptible to certain cancers. For example, asbestos workers have an increased incidence of lung cancer. Similarly, a higher likelihood of getting bladder cancer is associated with dye, rubber and gas workers; skin and lung cancer with smelters, gold miners and arsenic workers; leukemia with glue and varnish workers; liver cancer with PVC manufacturers; and lung, bone and bone marrow cancer with radiologists and uranium miners.

Ultra-violet radiation from the sun accounts for a majority of melanoma deaths. Other sources of radiation are x rays, radon gas, and ionizing radiation from nuclear material. Several studies have shown that there is a well-established link between asbestos and cancer. Chlorination of water may account for a small rise in cancer risk. However, the main danger from pollution occurs when dangerous chemicals from the industries escape into the surrounding environment. Cancer is a progressive disease, and goes through several stages. Each stage may produce a number of symptoms. Some symptoms are produced early and may occur due to a tumor that is growing within an organ or a gland. As the tumor grows, it may press on the nearby nerves, organs, and blood vessels.

This causes pain and some pressure which may be the earliest warning signs of cancer. Despite the fact that there are several hundred different types of cancers, producing very different symptoms, the ACS has established the following seven symptoms as possible warning signals of cancer:. Many other diseases, besides cancer, could produce the same symptoms. However, it is important to have these symptoms checked, as soon as possible, especially if they linger.

The earlier a cancer is diagnosed and treated, the better the chance of it being cured. Many cancers such as breast cancer may not have any early symptoms. Therefore, it is important to undergo routine screening tests such as breast self-exams and mammograms. Diagnosis begins with a thorough physical examination and a complete medical history. The doctor will observe, feel and palpate apply pressure by touch different parts of the body in order to identify any variations from the normal size, feel, and texture of the organ or tissue. As part of the physical exam, the doctor will inspect the oral cavity, or the mouth.

By focusing a light into the mouth, he will look for abnormalities in color, moisture, surface texture, or presence of any thickening or sore in the lips, tongue, gums, the hard palate on the roof of the mouth, and the throat. To detect thyroid cancer , the doctor will observe the front of the neck for swelling. He may gently manipulate the neck and palpate the front and side surfaces of the thyroid gland located at the base of the neck to detect any nodules or tenderness.

As part of the physical examination, the doctor will also palpate the lymph nodes in the neck, under the arms and in the groin. Many illnesses and cancers cause a swelling of the lymph nodes. The doctor may conduct a thorough examination of the skin to look for sores that have been present for more than three weeks and that bleed, ooze, or crust; irritated patches that may itch or hurt, and any change in the size of a wart or a mole.

Examination of the female pelvis is used to detect cancers of the ovaries, uterus, cervix, and vagina. In the visual examination, the doctor looks for abnormal discharges or the presence of sores. Then, using gloved hands the physician palpates the internal pelvic organs such as the uterus and ovaries to detect any abnormal masses. Breast examination includes visual observation where the doctor looks for any discharge, unevenness, discoloration, or scaling.

The doctor palpates both breasts to feel for masses or lumps. For males, inspection of the rectum and the prostate is also included in the physical examination. The doctor inserts a gloved finger into the rectum and rotates it slowly to feel for any growths, tumors, or other abnormalities. The doctor also conducts an examination of the testes, where the doctor observes the genital area and looks for swelling or other abnormalities. The testicles are palpated to identify any lumps, thickening or differences in the size, weight and firmness. If the doctor detects an abnormality on physical examination, or the patient has some symptom that could be indicative of cancer, the doctor may order diagnostic tests.

Laboratory studies of sputum sputum cytology , blood, urine, and stool can detect abnormalities that may indicate cancer. Sputum cytology is a test where the phlegm that is coughed up from the lungs is microscopically examined. It is often used to detect lung cancer. A blood test for cancer is easy to perform, usually inexpensive and risk-free. The blood sample is obtained by a lab technician or a doctor by inserting a needle into a vein and is relatively painless. Blood tests can be either specific or non-specific. Often, in certain cancers, the cancer cells release particular proteins called tumor markers and blood tests can be used to detect the presence of these tumor markers.

However, with a few exceptions, tumor markers are not used for routine screening of cancers, because several non-cancerous conditions also produce positive results. Blood tests are generally more useful in monitoring the effectiveness of the treatment, or in following the course of the disease and detecting recurrent disease. Imaging tests such as computed tomography scans CT scans , magnetic resonance imaging MRI , ultrasound and fiberoptic scope examinations help the doctors determine the location of the tumor even if it is deep within the body. Conventional x rays are often used for initial evaluation, because they are relatively cheap, painless and easily accessible.

In order to increase the information obtained from a conventional x ray, air or a dye such as barium or iodine may be used as a contrast medium to outline or highlight parts of the body. The most definitive diagnostic test is the biopsy, wherein a piece of tissue is surgically removed for microscope examination. Besides confirming a cancer, the biopsy also provides information about the type of cancer, the stage it has reached, the aggressiveness of the cancer and the extent of its spread. Since a biopsy provides the most accurate analysis, it is considered the gold standard of diagnostic tests.

Screening examinations conducted regularly by healthcare professionals can result in the detection of cancers of the breast, colon, rectum, cervix, prostate, testis, tongue, mouth, and skin at early stages, when treatment is more likely to be successful. Some of the routine screening tests recommended by the ACS are sigmoidoscopy for colorectal cancer , mammography for breast cancer , pap smear for cervical cancer , and the PSA test for prostate cancer.

Self-examinations for cancers of the breast, testes, mouth, and skin can also help in detecting the tumors before the symptoms become serious. A recent revolution in molecular biology and cancer genetics has contributed a great deal to the development of several tests designed to assess one's risk of getting cancers. These new techniques include genetic testing , where molecular probes are used to identify mutations in certain genes that have been linked to particular cancers.

At present, however, there are a lot of limitations to genetic testing and its utility appears ambiguous, emphasizing the need to develop better strategies for early detection. Treatment and prevention of cancers continue to be the focus of a great deal of research. In , research into new cancer therapies included cancertargeting gene therapy , virus therapy, and a drug that stimulated apoptosis, or self-destruction of cancer cells, but not healthy cells. However, all of these new therapies take years of clinical testing and research.

The aim of cancer treatment is to remove all or as much of the tumor as possible and to prevent the recurrence or spread of the primary tumor. While devising a treatment plan for cancer, the likelihood of curing the cancer has to be weighed against the side effects of the treatment. If the cancer is very aggressive and a cure is not possible, then the treatment should be aimed at relieving the symptoms and controlling the cancer for as long as possible.

Cancer treatment can take many different forms, and it is always tailored to the individual patient. The decision on which type of treatment is the most appropriate depends on the type and location of cancer, the extent to which it has already spread, the patient's age, sex, general health status and personal treatment preferences. The major types of treatment are: surgery, radiation, chemotherapy , immunotherapy, hormone therapy, and bone-marrow transplantation.

Surgery is the removal of a visible tumor and is the most frequently used cancer treatment. It is most effective when a cancer is small and confined to one area of the body. Treatment of cancer by surgery involves removal of the tumor to cure the disease. This is typically done when the cancer is localized to a discrete area. Along with the cancer, some part of the normal surrounding tissue is also removed to ensure that no cancer cells remain in the area.

Since cancer usually spreads via the lymphatic system, adjoining lymph nodes may be examined and sometimes are removed as well. Preventive surgery. Preventive or prophylactic surgery involves removal of an abnormal looking area that is likely to become malignant over time. Rather than live with the fear of developing colon cancer, these people may choose to have their colons removed and reduce the risk significantly. Diagnostic purposes. The most definitive tool for diagnosing cancer is a biopsy. Sometimes, a biopsy can be performed by inserting a needle through the skin. However, at other times, the only way to obtain a tissue sample for biopsy is by performing a surgical operation. Cytoreductive surgery is a procedure where the doctor removes as much of the cancer as possible, and then treats the remaining area with radiation therapy or chemotherapy or both.

Palliative surgery is aimed at curing the symptoms, not the cancer. Usually, in such cases, the tumor is so large or has spread so much that removing the entire tumor is not an option. For example, a tumor in the abdomen may be so large that it may press on and block a portion of the intestine, interfering with digestion and causing pain and vomiting. In tumors that are dependent on hormones, removal of the organs that secrete the hormones is an option. For example, in prostate cancer, the release of testosterone by the testicles stimulates the growth of cancerous cells. Hence, a man may undergo an "orchiectomy" removal of testicles to slow the progress of the disease. Similarly, in a type of aggressive breast cancer, removal of the ovaries oophorectomy will stop the synthesis of hormones from the ovaries and slow the progression of the cancer.

Radiation kills tumor cells. Radiation is used alone in cases where a tumor is unsuitable for surgery. More often, it is used in conjunction with surgery and chemotherapy. Radiation can be either external or internal. In the external form, the radiation is aimed at the tumor from outside the body. In internal radiation also known as brachytherapy , a radioactive substance in the form of pellets or liquid is placed at the cancerous site by means of a pill, injection or insertion in a sealed container. Chemotherapy is the use of drugs to kill cancer cells. It destroys the hard-to-detect cancer cells that have spread and are circulating in the body.

Chemotherapeutic drugs can be taken either orally by mouth or intravenously, and may be given alone or in conjunction with surgery, radiation or both. When chemotherapy is used before surgery or radiation, it is known as primary chemotherapy or "neoadjuvant chemotherapy. It can therefore be used effectively to reduce the size of the tumor for surgery or target it for radiation. However, the toxic effects of neoadjuvant chemotherapy are severe.

In addition, it may make the body less tolerant to the side effects of other treatments that follow such as radiation therapy. The more common use of chemotherapy is adjuvant therapy, which is given to enhance the effectiveness of other treatments. For example, after surgery, adjuvant chemotherapy is given to destroy any cancerous cells that still remain in the body. In , a new technique was developed to streamline identification of drug compounds that are toxic to cancerous cells but not to healthy cells.

The technique identified nine dugs, one of which had never before been identified for use in cancer treatment. Researchers began looking into developing the new drug for possible use. Immunotherapy uses the body's own immune system to destroy cancer cells. This form of treatment is being intensively studied in clinical trials and is not yet widely available to most cancer patients. The various immunological agents being tested include substances produced by the body such as the interferons, interleukins, and growth factors , monoclonal antibodies, and vaccines. Unlike traditional vaccines, cancer vaccines do not prevent cancer. Instead, they are designed to treat people who already have the disease.

Cancer vaccines work by boosting the body's immune system and training the immune cells to specifically destroy cancer cells. Hormone therapy is standard treatment for some types of cancers that are hormone-dependent and grow faster in the presence of particular hormones. These include cancer of the prostate, breast, and uterus. Hormone therapy involves blocking the production or action of these hormones. As a result the growth of the tumor slows down and survival may be extended for several months or years. The bone marrow is the tissue within the bone cavities that contains blood-forming cells.

Healthy bone marrow tissue constantly replenishes the blood supply and is essential to life. Sometimes, the amount of drugs or radiation needed to destroy cancer cells also destroys bone marrow. Replacing the bone marrow with healthy cells counteracts this adverse effect. A bone marrow transplant is the removal of marrow from one person and the transplant of the blood-forming cells either to the same person or to someone else.

Bone-marrow transplantation, while not a therapy in itself, is often used to "rescue" patients, by allowing those with cancer to undergo aggressive therapy. Many different specialists generally work together as a team to treat cancer patients. An oncologist is a physician who specializes in cancer care. The oncologist provides chemotherapy, hormone therapy, and any other non-surgical treatment that does not involve radiation. The oncologist often serves as the primary physician and coordinates the patient's treatment plan. The radiation oncologist specializes in using radiation to treat cancer, while the surgical oncologist performs the operations needed to diagnose or treat cancer. Gynecologist-oncologists and pediatric-oncologists, as their titles suggest, are physicians involved with treating women's and children's cancers respectively.

Many other specialists also may be involved in the care of a cancer patient. For example, radiologists specialize in the use of x rays, ultrasounds, CT scans, MRI imaging and other techniques that are used to diagnose cancer. Hematologists specialize in disorders of the blood and are consulted in case of blood cancers and bone marrow cancers. Pancreatic cancer is a lethal disease, with nearly 49, deaths in the US in As such, there has been interest in extending the extent of surgery in an attempt to increase survival. However, the impact of extent of lymphadenectomy on recurrence and overall survival remains more controversial.

Besselink MD, PhD. Pancreatic resections are among the most technically demanding procedures, including high risk of potentially life-threatening complications and outcomes strongly correlated to hospital volume and individual surgeon experience. This study reviews and summarizes the available randomized controlled trials evaluating the role of minimally invasive approaches both robot-assisted and laparoscopic for pancreatic resections. Pancreatic cancer is one of the most aggressive gastrointestinal malignancies despite multimodality therapy.

In the last several years, genomic studies have revealed that carcinogenesis is driven largely by key driver mutations that can be targeted for oncologic therapy. These strategies have generated a paradigm shift in the management of several cancer types, including those in the gastrointestinal tract. However, there are several complicating factors when translating the results to pancreatic cancer, including the dense, fibrotic stroma unique to this disease that may shield the cancer cells from both cytotoxic and immunologic agents. Although the majority of trials have been performed in the metastatic setting, this review will focus on both the historic studies that have defined this field as well as the emerging data arising from ongoing efforts to exploit newly discovered mutations and their druggable targets.

Pancreatic fistula has been the defining complication and challenge of pancreatic surgery. Better awareness and mitigation of postoperative pancreatic fistulas has led to significant improvements in morbidity and mortality of pancreatic surgery. The definition and management of pancreatic fistulas has sequentially progressed over the last three decades; the literature ranges from retrospective, observational studies to prospective multicenter randomized controlled trials. The landmark literature contributions driving the perioperative management of pancreatic fistulas are detailed in this article. Pancreatic neuroendocrine tumors PNETs comprise a heterogeneous group of neoplasms arising from pancreatic islet cells that remain relatively rare but are increasing in incidence worldwide.

While significant advances have been made in recent years with regard to systemic therapies for patients with advanced disease, surgical resection remains the standard of care for most patients with localized tumors. Although formal pancreatectomy with regional lymphadenectomy is the standard approach for most PNETs, pancreas-preserving approaches without formal lymphadenectomy are acceptable for smaller tumors at low risk for lymph node metastases. Hilar cholangiocarcinoma HC is a rare and highly aggressive biliary tract neoplasm. As such, the data driving the management of this disease generally are not based on prospective clinical trial data but rather consist of retrospective experiences and limited level 1 data. Surgical resection offers the best chance of a long-term survival, but local and distant recurrences are common.

This report presents landmark articles that form the basis of preoperative, operative, and adjuvant strategies for HC. Pancreaticoduodenectomy is one of the more complicated operations that exists in surgery, and is fraught with potential morbidity, the most well-known, and dreaded, of which is the pancreatic leak. While much of the risk associated with pancreatic leak is inherent to the operation, there have been no shortage of techniques employed by surgeons to try to mitigate that risk.

In-transit melanoma represents a distinct disease pattern in which melanoma recurs as dermal or subcutaneous nodules between the primary melanoma site and the draining regional lymph node basin. The disease pattern is often not amenable to complete surgical resection. Here are reviewed landmark studies describing and evaluating regional chemotherapy and intralesional therapies for patients with in-transit melanoma metastases. Ann Surg Oncol 27,35 — 43 This article reviews the landmark clinical trials that led to the first FDA-approved drugs for basal cell carcinoma, squamous cell carcinoma, and Merkel cell carcinoma and places them in the context of current national guidelines.

Ann Surg Oncol 27, 22 — 27 Between there have been six randomized controlled trials RCTs performed to evaluate the width of surgical margin excision for primary cutaneous melanoma and its influence on recurrence and survival. These RTCs, related current recommendations and long-term follow-up data, as well as a contemporary, actively enrolling trial are summarized and discussed in this Landmark Series. Ann Surg Oncol 27, 3 — 12 Until the advent of effective systemic therapy for melanoma, there was virtually no possibility for an effective approach with neoadjuvant systemic therapy NAST. Management of regional lymph nodes in patients with melanoma has evolved significantly in recent years.

The value of nodal intervention, long utilized for its perceived therapeutic benefit, has now shifted to that of a critical prognostic procedure used to guide clinical decision making. Michael E. Kimbrough, MD, Arnold J. Stromberg, PhD, Amy R. Quillo, MD, Robert C. Guidelines for surgical management of SBNETs rely on retrospective data, which suggest that primary tumor resection and cytoreduction improve symptoms, prevent future complications, and lengthen survival. In advanced NETs, improvement in progression-free survival has been reported in large, randomized, controlled trials of various medical treatments, including somatostatin analogues, targeted therapy, and peptide receptor radionuclide therapy.

Multimodality treatment of primary soft tissue sarcoma has evolved over the last 50 years, including seminal studies in amputation versus limb-sparing surgery, incorporation of radiation therapy XRT , and the continuing controversy over the utilization and efficacy of systemic chemotherapy. We review the landmark studies in the multimodality management of primary extremity and trunk soft tissue sarcoma. Desmoid-type fibromatosis represents a challenge in the landscape of surgical oncology, for several reasons. The tumors can be infiltrative and locally aggressive, surgery may be morbid, and patients are usually young, and thus treatment sequelae must be managed for decades.

Desmoids do not have metastatic potential, therefore management strategies for desmoids have evolved to employ frontline treatments that are largely non-operative. In fact, with unpredictable and benign behavior, we now recognize that desmoids can also stabilize and regress, making active observation an option for many patients. Moreover, many medical therapies are active in the disease.

We reviewed landmark studies describing contemporary issues that affect treatment recommendations for desmoid patients: prognostic factors, indication to active surveillance, role of surgical margins, postoperative radiotherapy, and the most recent expert consensus papers. The treatment of mesothelioma has evolved slowly over the last 20 years. While surgery as a standalone treatment has fallen out of favor, the importance of multimodality treatment consisting of combinations of chemotherapy, radiotherapy, and surgery have become more common in operable, fit patients.

In this review, we discuss trials in surgery, chemotherapy, and radiation that have shaped contemporary multimodality treatment of this difficult malignancy, and we touch on the new and emerging immunotherapeutic and targeted agents that may change the future treatment of this disease. We also review the multimodality treatment regimens, with particular attention to trimodality therapy and neoadjuvant hemithoracic radiation strategies. Despite this, a universally accepted algorithm to guide clinical decision-making remains elusive. The controversy surrounding the management of stage 3A NSCLC stems primarily from the innate heterogeneity of the disease and the varied results observed with treatment. Early studies established that surgery alone yields poor survival rates for patients with NSCLC and ipsilateral mediastinal lymph node involvement, likely due to the presence of residual mediastinal disease after resection.

The findings from these landmark studies are reviewed and summarized. Skip to content. The Landmark Series. Breast Cancer. Carla S. Fischer, MD, Julie A. Margenthaler, MD, Kelly K.
