Treatment outcome of angiocentric T-cell and NK/T-cell lymphoma, nasal type: radiotherapy versus chemoradiotherapy

Abstract

OBJECTIVE: The purpose of this study was to evaluate the treatment outcome of angiocentric T-cell and natural killer (NK)/T-cell lymphoma, nasal type. METHODS: Between February 1989 and March 2001, 53 patients with newly diagnosed angiocentric T-cell and NK/T-cell lymphoma, nasal type involving the head and neck, were treated with radiation therapy (RT). There were 37 males and 16 females. The median age of the patients was 45 years (range 19-73). Twenty of them were treated with chemoradiotherapy (CRT), while 33 with treated with RT alone. The median follow-up period was 74 months (range 6-173). RESULTS: The 5-year overall survival rate of all patients was 69%. CRT appeared to be inferior to RT alone in terms of 5-year overall survival, though the difference was not statistically significant (59 versus 76%, P = 0.27). CONCLUSIONS: There was no difference in survival between RT and CRT in angiocentric T-cell and NK/T-cell lymphoma, nasal type.
