Summary

The researchers are doing this study to test the safety of combining bexarotene with TSEB radiotherapy in people who have a common form of CTCL called mycosis fungoides (MF).

Bexarotene is a form of vitamin A that activates proteins called retinoid X receptors, which may stop the growth of cancer cells and kill them. TSEB radiotherapy is a type of radiation therapy that treats the entire surface of the skin with very low doses of radiation to kill cancer cells and shrink tumors. This type of radiation does not pass through the outer layers of the skin into the tissues and organs below the skin.

The study researchers think that giving bexarotene treatment at the same time as treatment with TSEB radiotherapy may be more effective against MF than either treatment given alone or in sequence (one after the other).

Conditions

  • Cutaneous T-cell Lymphoma

Interventions

DRUG

Bexarotene

Orally every day starting at the dose of 150 mg/day flat dose. At Day 15, if the treatment is tolerated, patients will escalate the dose of bexarotene to 300 mg/day, and that dose will remain constant during the rest of the study.

RADIATION

Total Skin Electron Beam (TSEB)

At Day 21, if the bexarotene has shown to be tolerated, patients will receive the first dose of TSEB (2 Gy x 2).
