-
- Malignant Melanoma is a common skin cancer that arises from the melanin
- cells of the upper layer of the skin (epidermis) or from similar cells that
- can be found in moles (nevi). This type of skin cancer may send down roots
- into deeper layers of the skin. Some of these microscopic roots can spread
- (metastasize) causing new tumor growths in vital organs of the body.
-
- Symptoms
-
- In early stages most melanomas do not produce any specific symptoms. Later
- they may appear as a lesion that does not heal, or an existing mole that
- shows changes in size or color. A physician should be consulted when any
- lesion, pigmented or not, becomes itchy, burns, softens or hardens, forms a
- scab, bleeds, becomes surrounded by a reddened or inflamed area, changes
- color, size or shape.
-
- Disorder Subdivisions:
-
- Acral Lentiginious melanoma is a malignant skin cancer that occurs in
- areas that are not excessively exposed to sunlight and where hair follicles
- are absent.
-
- Juvenile Melanoma is a benign, elevated, pink to purplish-red papule,
- with a slightly scaly surface. It usually appears on the face, especially
- the cheeks. This type of melanoma most often occurs before puberty and has
- been mistaken for malignant melanoma.
-
- Malignant Lentigo (Melanoma) is a precancerous area on the skin, that
- resembles a freckle. It can be brown or black in color, irregular in shape,
- and it usually occurs on the face. This type of Melanoma occurs most often
- in older people.
-
- Causes
-
- The exact cause of Malignant Melanoma is unknown. Excessive exposure to the
- sun, particularly before puberty, and living in areas that are closer to the
- sun, increases the risk of developing skin cancer. There may be a genetic
- predisposition for malignant melanoma which may be transmitted through
- autosomal dominant genes.
-
- Human traits including the classic genetic diseases are the product of
- the interaction of two genes for that condition, one received from the father
- and one from the mother. In dominant disorders a single copy of the disease
- gene (received from either the mother or father) will be expressed
- "dominating" the other normal gene and resulting in appearance of the
- disease. The risk of transmitting the disorder from affected parent to
- offspring is 50% for each pregnancy regardless of the sex of the resulting
- child. A genetic predisposition to an illness means that some people may
- carry the defective gene but never get the disorder unless something in the
- environment triggers the disease process.
-
- Affected Population
-
- Malignant Melanoma affects males and females in equal numbers. The incidence
- of these types of skin cancers is increasing at a far faster rate than any
- other cancers. The risk of melanoma is higher in Caucasians than in those of
- more darkly pigmented races. It is even a greater risk for those with blue
- eyes and fair complexion.
-
- Related Disorders
-
- Symptoms of the following disorders can be similar to those of Malignant
- Melanoma. Comparisons may be useful for a differential diagnosis:
-
- Basal Cell Carcinoma is a common skin cancer. It may appear as
- small, shiny, firm nodules; ulcerated, crusted lesions; or flat, scar-like
- hardened patches which may bleed. This type of skin cancer is difficult to
- differentiate from psoriasis or localized dermatitis without a biopsy.
-
- Squamous Cell Carcinomas usually appear on sun-exposed areas of the skin,
- but may occur anywhere on the body. The lesions begin as a small red
- elevation or patch with a scaly or crusted surface. They may become nodular,
- sometimes with a warty surface. In some, the bulk of the lesion may lie below
- the level of the surrounding tissue. A biopsy is essential to diagnose this
- disorder.
-
- Kaposi's Sarcoma may appear as small pigmented (tan to purple) papules,
- plaques, nodules, tumors or ulcers. This type of skin cancer can infiltrate
- the body, involving the oropharynx and gastrointestinal tract, disseminating
- to other organs such as the liver, lung and bone. Chemotherapy has been
- helpful in treating Kaposi's Sarcoma. Until the last 10 years it was seen
- mostly in older men of Ashkenazi Jewish or Mediterranean descent, and those
- with a compromised immune system. The more recent increased incidence of
- Kaposi's Sarcoma is due to AIDS (Acquired Immunodeficiency Syndrome); about
- 30% of those with AIDS will also get Kaposi's Sarcoma.
-
- Therapies: Standard
-
- The treatment for Malignant Melanoma depends on the level, stage and location
- of the skin cancer at the time of diagnosis. For stage 1 disease, surgery to
- remove the affected area is a wide excision with 5-cm margins around the
- lesion. In some locations, such as the face, smaller margins must be
- accepted. If the cancer has progressed to the lymph nodes, Stage 2, a
- complete removal of the involved nodes (lymphadenectomy) must be done.
- Regular follow-ups are advisable and should include an annual chest X-Ray.
-
- For patients with metastatic disease, certain chemotherapeutic agents
- (drugs), are being used alone or in combination with other drugs.
- Decarbazine, used in this manner has resulted in a temporary remission for
- some patients. A course of treatment that includes high-dose alkylating
- agents such as cyclophosphamide, cisplatin, and carmustine, may also be
- effective as a treatment for Malignant Melanoma.
-
- Therapies: Investigational
-
- at the present time there are several new drug studies dealing with Malignant
- Melanoma. Scientists are trying to develop drugs to enhance the immune
- system, including a vaccine. The drug Interferon, used alone or in
- combination with other chemotherapeutic agents, is also being tested.
- Autologous bone marrow transplants are being done experimentally for
- treatment of Malignant Melanoma. More research must be conducted to
- determine long-term safety and effectiveness of these drugs and procedures.
-
- The Office of Orphan Products Development has awarded a New Grant Award
- for the year 1990 to Dr. Jean Claude Bystryn of New York Medical Center, New
- York, NY, for clinical trial work of a Polyvalent Antigen Vaccine for
- treatment of Melanoma.
-
- Clinical trials are underway to study Interleukin-2 and Tumor-
- Infiltrating Lymphocytes in patients with Melanoma. Interested persons may

-
- The orphan product Melphalan, trade name Alkeran for injection, is being
- tested by the FDA as a treatment for Metastic Melanoma. The product is being
