Objective To determine the efficacy of palliative radiotherapy in treating tumor-stage cutaneous T-cell lymphoma/mycosis fungoides(MF).Methods From January 2008 to January 2013,a total of 11 patients with tumor-stage MF were treated with local radiation therapy in Peking Union Medical College Hospital.The median age of these patients was 53.36±14.45 years.Female-male ratio was 1:1.2.The average course of disease was 10.82±3.37 years.All the patients were treated with local electronic beam irradiation with a total median dosage of 48.55±9.51(40-74) Gy in an average of 24.55±5.57(20-40) fractions,5 fractions per week.Results The median follow-up time was 55.27±29.3(13-103) months.No severe acute or chronic side effects of irradiation were observed.Complete clinical response(CR) rate of the radiated sites was 54.5%(6/11),partial response(PR) rate was 36.4%(4/11),and the overall response rate(CR+PR) was 90.9%.One patient showed no response.Conclusion Local radiotherapy with psolaren plus ultraviolet A and/or interferon maintaining treatment is an effective palliative therapy in the treatment of tumor-stage MF patients.
