One reason for this worse prognosis is that nasal NK/T cell lymphoma is resistant to standard sequential chemoradiotherapy. Thus, we adopted concurrent chemoradiotherapy using a CHOP-like regimen for treating stage I nasal NK/T cell lymphoma. Case 1 was treated with concurrent chemoradiotherapy using 41-Gy irradiation with 12 cycles of the CHOP-like regimen (THP-CVP). Case 2 was treated with concurrent chemoradiotherapy using 50-Gy irradiation with 10 cycles of THP-CVP. In both Case 1 and Case 2, the tumors disappeared after chemoradiotherapy. The Case 1 patient is still alive with 45 months free of relapse. The Case 2 patient is also still alive with 39 months free of relapse. These results suggest that concurrent chemoradiotherapy using a CHOP-like regimen for stage I nasal NK/T cell lymphoma provided sufficient dose intensity and may be a useful treatment option.
