PURPOSE: The aim of this study was to evaluate the outcomes of total skin electron beam therapy (TSEBT) with "translational technique" in the management of mycosis fungoides (MF).
METHODS: Between January 1995 and October 2014, 51 patients with MF were treated using TSEBT with translational technique. The total dose was 2800-3600 cGy, de-livered in 7 to 20 fractions. Out of the total 51 patients, 22 (43.1%) had T2 (generalized patch/plaque) disease, 20 (39.3%) had T3 disease (tumor stage), and 9 (17.6%) had T4 (erythrodermic) disease. Radiation-related late skin injury parameters including atrophy, pigmentation changes, hair loss, telangiectasia and ulceration were assessed according to RTOG/EORTC Late Radiation Morbidity Scoring Schema after at least 3 months from TSEBT.
RESULTS: Treatment response was categorized as complete remission (CR), partial remission (PR), or non-responding (NR) lesions. After TSEBT with translational technique, CR rate was 68.6% and PR rate 23.5%, while the NR rate was 7.9%. Overall, the rates of grade 1, grade 2, grade 3, and grade 4 toxicity were 17.6% )9 patients), 39.3% (20 patient), 35.3% (18 patients), and 7.8% (4 patients), respectively. At a median follow-up of 79 months (range 14-142), overall survival (OS) and disease-free survival (DFS) rates were 83% and 46%, respectively.
CONCLUSION: For patients with MF refractory to topical chemotherapy and phototherapy, TSEBT with translational technique offers excellent local control (LC: CR+PR) and favorable OS rates along with substantial relief of symptoms.
