Total Skin Electron Beam Therapy with Rotary Dual Technique as Palliative Treatment for Mycosis Fungoides

In Vivo. 2018 May-Jun;32(3):517-522. doi: 10.21873/invivo.11269.

Abstract

Background/aim: The aim of the study was to retrospectively assess the efficacy and toxicity of total skin electron beam therapy (TSEBT) in patients with primary cutaneous T-cell lymphoma (MF, mycosis fungoides) at various stages of development.

Patients and methods: Treatment results of 40 patients with MF stage IB-III, treated between 2001 and 2015, were reviewed. Median total dose was 32 Gy, delivered to the entire skin surface. Median follow-up was 60 months.

Results: Clinical complete response was documented in 29 and partial response in 11 patients. The clinical response significantly influenced overall survival (OS) (p=0.002) and progression-free survival (PFS) (p<0.001). Mean OS was 76 months. Mean PFS was 48.9 months and current one- and two-year PFS were 67.5% and 55%, respectively. A statistically significant correlation was found between partial and total remission time and stages of the lymphoma (p=0.015).

Conclusion: TSEBT is an efficient and well-tolerated palliative treatment for symptomatic primary cutaneous T-cell lymphoma.

Keywords: Mycosis fungoides; overall survival; progression free survival; radiotherapy; toxicity.
