Basal Cell Carcinoma
Squamous Cell Carcinoma

A link to a list of current clinical trials is included for each treatment section. For some types or stages of cancer, there may not be any trials listed. Check with your doctor for clinical trials that are not listed here but may be right for you.

Treatment of basal cell carcinoma may include the following:

• Mohs micrographic surgery.
• Simple excision.
• Electrodesiccation and curettage.
• Cryosurgery.
• Radiation therapy.
• Laser surgery.
• Topical chemotherapy with fluorouracil.
• Photodynamic therapy.
• A clinical trial of biologic therapy.

Follow-up skin exams are important for people with basal cell carcinoma because they are likely to have a new or recurrent tumor within 5 years of the first one. After treatment, the patient should have skin exams every 6 months for 5 years and once a year after that.

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with basal cell carcinoma of the skin ¹. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site ².

Treatment of squamous cell carcinoma may include the following:

• Mohs micrographic surgery.
• Simple excision.
• Electrodesiccation and curettage.
• Cryosurgery.
• Radiation therapy.
• Topical chemotherapy with fluorouracil.
• Laser surgery.
• A clinical trial of biologic therapy.
• A clinical trial of biologic therapy and retinoids.

Follow-up skin exams are important for people with squamous cell carcinoma. Because squamous cell carcinoma can spread, patients should have skin exams every 3 months for several years after treatment and then every 6 months.

Glossary Terms

A type of skin cancer that arises from the basal cells, small round cells found in the lower part (or base) of the epidermis, the outer layer of the skin.

Treatment to boost or restore the ability of the immune system to fight cancer, infections, and other diseases. Also used to lessen certain side effects that may be caused by some cancer treatments. Agents used in biological therapy include monoclonal antibodies, growth factors, and vaccines. These agents may also have a direct antitumor effect. Also called biological response modifier therapy, biotherapy, BRM therapy, and immunotherapy.

A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease. Also called clinical study.

A procedure in which tissue is frozen to destroy abnormal cells. This is usually done with a special instrument that contains liquid nitrogen or liquid carbon dioxide. Also called cryoablation.

Removal of tissue with a curette (a spoon-shaped instrument with a sharp edge).

The drying of tissue by a high-frequency electric current applied with a needle-shaped electrode.

Removal by surgery.

A drug used to treat symptoms of cancer of the colon, breast, stomach, and pancreas. It is also used in a cream to treat certain skin conditions. Fluorouracil stops cells from making DNA and it may kill cancer cells. It is a type of antimetabolite. Also called 5-fluorouracil and 5-FU.

Monitoring a person's health over time after treatment. This includes keeping track of the health of people who participate in a clinical study or clinical trial for a period of time, both during the study and after the study ends.

A surgical procedure that uses the cutting power of a laser beam to make bloodless cuts in tissue or to remove a surface lesion such as a tumor.

A surgical procedure used to treat skin cancer. Individual layers of cancerous tissue are removed and examined under a microscope one at a time until all cancerous tissue has been removed. Also called Mohs micrographic surgery.

Treatment with drugs that become active when exposed to light. These activated drugs may kill cancer cells.

The use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiotherapy.

Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body. Also called recurrence.

Vitamin A or a vitamin A-like compound.

Cancer that begins in squamous cells, which are thin, flat cells that look like fish scales. Squamous cells are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the passages of the respiratory and digestive tracts. Also called epidermoid carcinoma.

The extent of a cancer in the body. Staging is usually based on the size of the tumor, whether lymph nodes contain cancer, and whether the cancer has spread from the original site to other parts of the body.

Treatment with anticancer drugs in a lotion or cream applied to the skin.
