When is radiotherapy recommended for cutaneous T-cell lymphoma?

Cutaneous T-cell lymphoma affects the skin, so radiation can be directed at a defined patch or group of lesions. The team considers the number, size, position and depth of the lesions, along with previous treatments and whether disease is present elsewhere. A limited treatment area may be suitable for local radiotherapy, while widespread skin involvement may call for a different plan or a combination of approaches.

Bring a list of skin treatments, medicines and changes you have noticed. Your team may examine the skin closely and review biopsy and imaging information before planning the radiation field. Ask how the treated area will be marked, how many visits are expected, whether hair or skin changes are likely in that area, and how the skin should be cared for during treatment.

Contact your oncology team promptly for rapidly changing lesions, increasing pain, bleeding, marked swelling, fever, or skin that becomes broken and difficult to care for. During treatment, report a spreading reaction, discharge or difficulty managing the treated skin so the team can assess it and adjust supportive care.

Ask which skin areas are being targeted, what benefit is expected, how treatment fits with your other lymphoma care, and which symptoms should trigger a same-day call. You can also ask about alternatives if the area is close to the eyes, mouth or another sensitive site.
