• #1 Skin Cancer – Melanoma: Practice Essentials, Overview, Diagnosis

  https://emedicine.medscape.com/article/846566-overview

  Skin cancers are the most common cancers, and malignant melanoma is the most serious form of skin cancer. Melanoma is the fifth most common cancer in the United States. […] Classic warning signs and symptoms of melanoma include any cutaneous lesion that changes color, size, or shape. Persistent pruritus is also a common early symptom. More advanced lesions frequently become friable, tender, painful, crusted, or ulcerated. […] The prognosis for and treatment of cutaneous melanoma depend greatly on the thickness of the lesion. Thus, the key to evaluation of suspected lesions is obtaining a full-thickness biopsy specimen. Excisional biopsy is the best choice for small lesions or for large lesions in cosmetically favorable locations. […] Staging of the melanoma adheres to the traditional tumor-node-metastasis (TNM) classification system. This system classifies melanomas according to local, regional, and distant characteristics, as follows: Stage I and II – Localized primary melanoma; Stage III – Metastasis to regional lymph node basin and/or any number of in-transit, satellite, and/or microsatellite metastases; Stage IV – Distant metastatic disease.

  Most melanomas are brought to a doctors attention because of signs or symptoms a person is having. […] If you have an abnormal area on your skin that might be cancer, your doctor will examine it and might do tests to find out if it is melanoma, another type of skin cancer, or some other skin condition. […] If melanoma is found, other tests might then be done to learn more about it, such as if it has spread to other areas of the body. […] The first step your doctor usually takes is to ask about your symptoms, such as when the mark on the skin first appeared, if it has changed in size or appearance, and if it has been painful, itchy, or bleeding. […] The doctor may also feel the lymph nodes (small bean-sized collections of immune cells) under the skin in the neck, underarm, or groin near the abnormal area.

  Most of us have spots on our skin. It’s important to notice any changes in the size, shape, and/or colour of your spots or moles. […] If you see a new spot or a change in an existing spot or mole, it needs to be checked by your doctor or a skin specialist. Your doctor checks the spots that have changed and do a general check of your skin. They will use a handheld magnifying tool called a dermatoscope to look at the spot or mole and judge it by the “ABCDE” criteria: Asymmetry The spot has an irregular shape. Border The spot has uneven or scalloped edges. Colour The spot has different shades and colour patches. Diameter The spot is usually over 6mm wide across. Evolving The spot is changing and growing. […] If your doctor thinks a spot on your skin could be melanoma, they will want to remove the whole spot or mole to look at it under a microscope. This is usually quick and simple.

  Dermatologists sometimes use special tools when trying to determine if an abnormal area might be a melanoma, and therefore if a skin biopsy is needed. […] Dermoscopy allows doctors to look at a suspicious area more closely, even giving them the ability to see some structures below the surface of the skin that cant be seen with the naked eye. […] If the doctor thinks a spot might be a melanoma, the suspicious area will be removed and sent to a lab to be looked at under a microscope. This is called a skin biopsy. […] No matter which type of biopsy is done, it should remove as much of the suspected area as possible so that an accurate diagnosis can be made. […] Biopsies of areas other than the skin may be needed in some cases. […] Special lab tests can be done on the biopsy samples that can tell whether it is a melanoma or some other kind of cancer.

• #1 Melanoma Diagnosis | Memorial Sloan Kettering Cancer Center

  https://www.mskcc.org/cancer-care/types/melanoma/diagnosis

  A biopsy is often the first step in diagnosing skin melanoma. During a biopsy, a doctor removes a small amount of tissue from the area where the cancer is suspected. The sample is sent to a pathologist, who examines it under a microscope and works with the other members of the care team to make a diagnosis. […] There are also several noninvasive techniques that doctors can use to evaluate possible melanomas. Dermoscopy is one common approach. It involves the use of a handheld device called a dermatoscope. This tool gives doctors a close-up view of the skin using a powerful microscope and special light. […] Molecular tests, such as fluorescence in situ hybridization (FISH) and comparative genomic hybridization (CGH), can be used to analyze the DNA of suspicious spots on the skin to help make difficult diagnoses.

  Melanoma can occur anywhere on the skin. […] Tests that examine the skin are used to diagnose melanoma. […] After melanoma has been diagnosed, tests may be done to find out if cancer cells have spread within the skin or to other parts of the body. […] The process used to find out if cancer has spread within the skin or to other parts of the body is called staging. […] To find out the stage of melanoma, the tumor is completely removed and nearby lymph nodes are checked for signs of cancer. […] The stage of melanoma depends on the thickness of the tumor, whether cancer has spread to lymph nodes or other parts of the body, and other factors. […] The following stages are used for melanoma: Stage 0 (melanoma in situ), Stage I (also called stage 1) melanoma, Stage II (also called stage 2) melanoma, Stage III (also called stage 3) melanoma, Stage IV (also called stage 4) melanoma.

  Another technique is called an excisional biopsy. An excisional biopsy uses a scalpel to cut away the entire mole and some of the healthy tissue around it. […] If you receive a diagnosis of melanoma, the next step is to determine the extent of the cancer, called the stage. […] To assign a stage to your melanoma, your healthcare team will: […] Determine the thickness. In general, the thicker the melanoma, the more serious the disease. […] The thickness of a melanoma is determined by looking at the melanoma under a microscope and measuring it with a special tool. […] The thickness of a melanoma helps your care team decide on a treatment plan. […] If there’s a risk that the cancer has spread to nearby lymph nodes, you might need a sentinel node biopsy. […] During a sentinel node biopsy, a dye is injected in the area where your melanoma was removed.

  The first lymph nodes to take up the dye are removed and tested for cancer cells. […] If they’re cancer-free, there’s a good chance that the melanoma has not spread. […] If there is concern that the melanoma has spread, imaging tests might be used to look for signs of cancer in other areas of the body. […] Your healthcare team uses the results from these tests to figure out your melanoma’s stage. […] Melanoma stages use the numbers 0 through 4. At stage 0 and stage 1, a melanoma is thin and small. Treatment is likely to be successful. […] As the melanoma grows deeper into the skin, the stages get higher. Treatment becomes more challenging. […] By stage 4, the cancer has spread beyond the skin to other organs, such as the lungs or liver.

  https://www.dana-farber.org/cancer-care/types/melanoma/diagnosis

  Blood tests and imaging tests, such as an X-ray, CT scan, MRI, and PET scan, are used to see if the cancer has spread: […] The results of these tests are viewed, along with the results of the biopsy, to determine the stage of the melanoma. […] The stage is based on: The depth of the original melanoma and other pathologic features of the original melanoma. Whether cancer cells have spread to nearby lymph nodes or to other parts of the body. […] In stage 0, melanoma is only in the epidermis (outer layer) of the skin. It is usually curable when removed with adequate margins. […] The tumor may be any thickness, with or without ulceration. One or more of the following applies: Cancer has spread to one or more lymph nodes. The melanoma cells have spread to adjacent tissues. […] The cancer has spread to other places in the body, including organs, distant skin areas, or lymph nodes far from the original growth.

  The sample of skin is sent to a pathologist, who looks at it under a microscope to check for cancer cells. […] Because melanoma can be hard to diagnose, you should consider having your biopsy checked by a second pathologist. […] After melanoma has been diagnosed, tests may be recommended to find out if cancer cells have spread within the skin or to other parts of the body. […] If you are diagnosed with melanoma skin cancer, your doctor will determine the stage (or extent) of the disease. Staging is a way of determining how much disease is in the body and where it has spread. This information is important because it helps your doctor determine the best type of treatment for you and the outlook for your recovery (prognosis). […] Melanoma staging is based on: Location(s) of the melanoma, Primary melanoma tumor thickness as well as other microscopic features, If it has spread to nearby lymph nodes if so, how many and what size, If it has spread (metastasized) to other parts of the body, A blood test called lactate dehydrogenase (LDH) for stage 4 melanoma. […] Stages 1 and 2 are based mainly on the thickness of the primary melanoma and other microscopic features. Stages 3 and 4 are based on how far the melanoma has spread from the skin; stage 3 melanoma signifies regional spread and stage 4 melanoma is based on distant spread.

• #1 Current state of melanoma diagnosis and treatment

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6804807/

  Melanoma is the deadliest form of skin cancer. In the early stages, melanoma can be treated successfully with surgery alone and survival rates are high, but after metastasis survival rates drop significantly. Therefore, early and correct diagnosis is key for ensuring patients have the best possible prognosis. Melanoma misdiagnosis accounts for more pathology and dermatology malpractice claims than any cancer other than breast cancer, as an early misdiagnosis can significantly reduce a patients chances of survival. […] Thus, new biomarkers and drug targets are needed to improve the accuracy of melanoma diagnosis and treatment. […] The early classification of melanoma was based on where the tumor arose from (existing nevus, acquired melanocytic lesion, blemish free skin), but in the 1960s a prominent dermatologist, Wallace Clark, suggested that melanoma ought to be classified based on histological features instead, thus revolutionizing the way melanoma was diagnosed.

  If the cancer is deep or has spread, surgery becomes more complex. […] If your dermatologist recommends a sentinel lymph node biopsy, it will also be performed in an operating room at a hospital. […] While surgery is usually the first choice for treating melanoma, surgery can be too risky for some patients. […] Observation (or more treatment) may be recommended for a patient in any stage. […] If your treatment plan calls for observation, you’ll be watched closely. […] After you finish treatment, your dermatologist (or oncologist) will still want to see you regularly. Melanoma can return or spread after treatment. […] It’s extremely important that you examine your skin and lymph nodes as often as your dermatologist or oncologist recommends.

This report has important information about your tumor. This is used to help guide treatment decisions for you. You should ask for a copy of this report to keep. […] The report will give the type of melanoma and some information about it that is needed for prognosis (prediction of the course of the disease) and treatment. […] Breslow’s depth of invasion measures the thickness of a melanoma, at its thickest point, in millimeters. This is important for prognosis. For example, a thicker melanoma has a poorer prognosis. Breslow thickness is more important than the tumor’s Clark’s Level in figuring out the prognosis.

  This test uses antibodies to check for antigens or markers in the tissue sample that indicate the presence of cancer cells. […] The GEP test can find the root of and diagnose a disease and determine how well the body may respond to treatment. A melanoma biopsy may be tested for mutations in certain genes because this information can help guide treatment decisions. […] Several medical imaging procedures, including a computed tomography (CT) scan, magnetic resonance imaging (MRI), positron emission tomography-computed tomography (PET-CT) scan or X-ray, may be used to detect cancer cells or tumors throughout the body. […] Your doctor may suggest testing your biopsy sample to see whether the cells express changes in certain genes. […] This information can help guide treatment decisions. […] Another gene test, DecisionDx-Melanoma, examines certain gene expression patterns in melanoma cells and can help you and your care team determine whether an early-stage melanoma is likely to spread or return, which can help further guide treatment options.

  The sample of skin is sent to a pathologist, who looks at it under a microscope to check for cancer cells. […] Because melanoma can be hard to diagnose, you should consider having your biopsy checked by a second pathologist. […] After melanoma has been diagnosed, tests may be recommended to find out if cancer cells have spread within the skin or to other parts of the body. […] If you are diagnosed with melanoma skin cancer, your doctor will determine the stage (or extent) of the disease. Staging is a way of determining how much disease is in the body and where it has spread. This information is important because it helps your doctor determine the best type of treatment for you and the outlook for your recovery (prognosis). […] Melanoma staging is based on: Location(s) of the melanoma, Primary melanoma tumor thickness as well as other microscopic features, If it has spread to nearby lymph nodes if so, how many and what size, If it has spread (metastasized) to other parts of the body, A blood test called lactate dehydrogenase (LDH) for stage 4 melanoma. […] Stages 1 and 2 are based mainly on the thickness of the primary melanoma and other microscopic features. Stages 3 and 4 are based on how far the melanoma has spread from the skin; stage 3 melanoma signifies regional spread and stage 4 melanoma is based on distant spread.

  If a melanoma tumor is 1 millimeter in thickness or more, and if the nearby lymph nodes dont feel swollen during a physical exam, our doctors may recommend a sentinel lymph node biopsy—a procedure that checks whether cancer cells are present in nearby lymph nodes. […] If melanoma cells are present in the lymph nodes, doctors may perform a variety of imaging tests to determine if the cancer has spread to other parts of the body, such as the lungs, brain, or liver. […] If you have melanoma, your doctors may ask that the cancerous tissue be examined for genetic changes or mutations. Certain gene mutations found in melanoma can tell doctors whether targeted drugs, which are designed to specifically block the growth of cancer cells, might be effective.

• #2 Diagnosis & Tests for Melanoma

  https://www.texasoncology.com/types-of-cancer/melanoma/diagnosis-tests-for-melanoma

  In order to diagnose a melanoma, a physician will remove the primary cancer and a pathologist will examine the sample under a microscope. Once melanoma is diagnosed, there are three critical factors that need to be determined: the thickness of the melanoma, the genomic profile of the melanoma, and whether or not the melanoma has spread (metastasized) to other parts of the body. […] The thickness of the melanoma is important because it will have an impact on whether the tumor has spread, which is the other critical factor used to determine the stage of disease. The thicker a melanoma is, the more likely it is to have spread to lymph nodes at the time of diagnosis. […] The sentinel lymph node (SLN) biopsy technique has improved the ability to detect small amounts of melanoma in lymph nodes.

  Your doctor may check your lymph nodes for melanoma by taking a biopsy. […] The first place that melanoma skin cancer usually spreads to is the nearby lymph nodes. […] During an SLNB your doctor removes the sentinel nodes and sends them to the laboratory. This is to check them for small amounts of melanoma that can only be seen under a microscope (microscopic disease). […] For stage 3 and 4, and some stage 2 melanoma skin cancers, your doctor tests the melanoma cells for gene changes (mutations). […] Doctors use CT or MRI scans to check if the melanoma has spread. […] You usually have a scan that looks at your: chest, tummy (abdomen) including the area between your hips, called the pelvis, head. […] The tests you have help your doctor find out if you have melanoma skin cancer and if it has spread. This is called the stage of a cancer. This is important because doctors recommend your treatment according to the stage.

  Dermatologists often use a technique called dermatoscopy or skin surface microscopy to evaluate skin spots and pigmented lesions. This technique allows the doctor to see microscopic structures under the skin not visible to the naked eye. […] A physician may also take a biopsy or skin sample to check the cells under a microscope for any evidence of cancer. […] If melanoma has already been diagnosed, nearby lymph nodes may be biopsied to see if the cancer has spread to this area of the body. […] A dematopathologist (a doctor who specializes in evaluating skin cancers) may also perform other tests to determine whether a melanoma is present. […] If an advanced melanoma is found, tumor biopsy samples may be tested for mutations in genes such as BRAF, NRAS, KIT, GNAQ, GNA11, and TRK, among others. […] Imaging tests are used mainly to look for the possible spread of melanoma to lymph nodes or other organs in the body. […] If melanoma has become invasive, the patient is likely to have a higher than normal blood level of lactate dehydrogenase (LDH).

• #2 Current state of melanoma diagnosis and treatment

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6804807/

  Clarks observations led to changes in the standard treatment for patients in the early stages of melanoma; he noted that patients with deeper cutaneous invasion (level III-V) were more likely to have lymph node invasion and determined that lymph node dissection should be limited only to patients with melanoma that had moved past the papillary dermis. […] The AJCC staging system provides pathologists and clinicians a guideline for staging patients diagnosed with melanoma. By combining histologic attributes of the primary tumor (T), the presence and extent of regional lymph node disease (N), and the presence and extent of distant metastasis (M), clinicians are able to assign patients a stage grouping that is strongly linked to survival and prognosis. […] To improve detection and diagnosis of melanoma (as well as other cancers), non-invasive imaging technology pre-biopsy and more quantitative techniques post-biopsy, such as fluorescence in situ hybridization (FISH), comparative genomic hybridization (CGH), sequencing, mass spectrometry (MS) and IHC are being used more frequently.

  Blood tests and imaging tests, such as an X-ray, CT scan, MRI, and PET scan, are used to see if the cancer has spread: […] The results of these tests are viewed, along with the results of the biopsy, to determine the stage of the melanoma. […] The stage is based on: The depth of the original melanoma and other pathologic features of the original melanoma. Whether cancer cells have spread to nearby lymph nodes or to other parts of the body. […] In stage 0, melanoma is only in the epidermis (outer layer) of the skin. It is usually curable when removed with adequate margins. […] The tumor may be any thickness, with or without ulceration. One or more of the following applies: Cancer has spread to one or more lymph nodes. The melanoma cells have spread to adjacent tissues. […] The cancer has spread to other places in the body, including organs, distant skin areas, or lymph nodes far from the original growth.

  The first lymph nodes to take up the dye are removed and tested for cancer cells. […] If they’re cancer-free, there’s a good chance that the melanoma has not spread. […] If there is concern that the melanoma has spread, imaging tests might be used to look for signs of cancer in other areas of the body. […] Your healthcare team uses the results from these tests to figure out your melanoma’s stage. […] Melanoma stages use the numbers 0 through 4. At stage 0 and stage 1, a melanoma is thin and small. Treatment is likely to be successful. […] As the melanoma grows deeper into the skin, the stages get higher. Treatment becomes more challenging. […] By stage 4, the cancer has spread beyond the skin to other organs, such as the lungs or liver.

  Melanoma is a type of cancer that usually starts in the skin, or more rarely, in the eye (ocular melanoma) or mucosal membranes of the body (mucosal melanoma). Melanoma specifically begins in melanocytes, cells that produce melanin, the pigment that gives skin, hair, and eyes their color. […] Melanoma is generally curable if diagnosed right away. But it is much more likely than other types of skin cancer to spread to other parts of the body if it isn’t treated early. […] Individuals should examine their skin head-to-toe once a month, looking for any suspicious spots, bumps, or lesions. It is important to tell a physician about any new moles or growths and any changes in the skin. […] Often the possibility of melanoma is brought to a doctor’s attention because of a symptom the patient has noticed, like a new or changing mole. If melanoma is suspected, your physician may use one or more of the following ways to understand if you have melanoma or not.

  One potential way to mitigate melanoma overdiagnosis, she continued, is to focus screening on those at increased risk of the disease. […] Incorporating these sorts of risk factors into physician decision-making would simultaneously increase the numbers of melanomas detected per individuals screened and reduce the total number of overdiagnoses, Dr. Leachman and her colleagues wrote. […] In addition to personal factors that can identify those at increased melanoma risk, noninvasive tools are becoming available that can help physicians make more informed choices about whether to remove suspicious moles and potentially reduce overdiagnosis. […] But more research is needed to determine if these technologies can help better identify truly dangerous melanomas and limit overdiagnosis, Dr. Brownell said.

  The use of IHC has even become important in staging systems. Beginning in the 7th ed AJCC, IHC was recommended in the evaluation of sentinel lymph nodes if tumor cells were not evident on HE, thus improving detection of micrometastasis. […] Ultimately, there is no perfect diagnostic or prognostic biomarker for melanoma. It is too diverse a disease to expect to find a single biomarker that can diagnose melanoma, which is why IHC screenings are often done in panels. […] The treatment of metastatic melanoma has greatly improved in recent years with the introduction of treatments such as BRAF, CTLA4 and PD1 inhibitors.
