Palliative total skin electron beam therapy (TSEBT) for advanced cutaneous T-cell lymphoma.

Our aim was to analyze the effectiveness of palliative total skin electron beam therapy (TSEBT) in the management of advanced cutaneous T-cell non-Hodgkin's lymphoma (CTCL). Eighteen patients (median age 59 years) with advanced and therapy-refractory CTCL in stages IIB-IV were treated with TSEBT for the first time. The most common histological subtype was Mycosis fungoides (72%). All patients suffered from lymphoma-associated symptoms. Median daily fractions of 1 Gy were administered up to a median total dose of 25 Gy. The median follow-up period was 11 months. Nine patients (50%) achieved a complete response and seven patients (39%) had a limited response. The actuarial one-year progression-free survival was 24%. Four patients (22%) had continuing remission over a median period of six months. Lymphoma associated symptoms were improved in 16 patients (89%). The median overall survival after receiving TSEBT was 12 months, resulting in an actuarial one-year overall survival of 48%. Treatment related acute effects (grade 1 or 2) were observed in all patients during radiation therapy. Transient grade 3 epitheliolyses developed in five patients (28%), late skin effects (grade 1 and 2) in 16 patients (89%), and hypohidrosis was seen in six patients (33%). We conclude that TSEBT is a very efficient and tolerable palliative treatment for patients with advanced CTCL.
