Different types of treatment are available for patients with mycosis fungoides and the Sézary syndrome. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
B-cell acute lymphoblastic leukemia is a cancer that affects your "B lymphocytes" -- white blood cells that grow in the soft center of your bones, called marrow.
B lymphocytes are supposed to grow into cells that help you fight infections. But in this disease, they turn into "leukemia" cells that live longer than normal cells and reproduce quickly. They build up in your bone marrow and move into your bloodstream. From there they can spread to other organs in your body.
Although in most cases it...
Photodynamic therapy is a cancer treatment that uses a drug and a certain type of laser light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein. The drug collects more in cancer cells than in normal cells. For skin cancer, laser light is shined onto the skin and the drug becomes active and kills the cancer cells. Photodynamic therapy causes little damage to healthy tissue. Patients undergoing photodynamic therapy will need to limit the amount of time spent in sunlight.
In one type of photodynamic therapy, called psoralen and ultraviolet A (PUVA) therapy, the patient receives a drug called psoralen and then ultraviolet radiation is directed to the skin. In another type of photodynamic therapy, called extracorporeal photochemotherapy, the patient is given drugs and then some blood cells are taken from the body, put under a special ultraviolet A light, and put back into the body.
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.
