Objectives: CD30(+) lymphoproliferative disorder is a rare variant of cutaneous T-cell lymphoma. Sustained complete response following first-line treatments is rare. This retrospective review evaluates the response of refractory or recurrent lesions to palliative radiation therapy.
Methods: The records of 6 patients with 12 lesions, treated with radiation therapy, were reviewed. All patients received previous first-line treatments. Patients with clinical and pathological evidence of symptomatic CD30(+) lymphoproliferative disorder, with no history of other cutaneous T-cell lymphoma variants, and with no prior radiation therapy to the index site were included.
Results: The median age of patients was 50.5 years (range, 15-83 years). Median size of the treated lesions was 2.5 cm (range, 2-7 cm). Four sites were treated with a single fraction of 750-800 cGy (n = 3) and 8 sites were treated with 4000-4500 cGy in 200-250 cGy fractions (n = 3). Radiation therapy was administered with electrons and bolus. Median follow-up was 113 months (range, 16-147 months). For all sites, there was 100% complete response with acute grade 1-2 dermatitis.
Conclusions: For recurrent and symptomatic radiation-naïve CD30(+) lymphoproliferative disorder lesions, palliative radiation therapy shows excellent response. A single fraction of 750-800 cGy is as effective as a multifractionated course and more convenient.
