Abstract：Objective To study the effects of different radiotherapy doses on the early stage nasal NK/T cell lymphoma. Methods 64 patients with early stage nasal NK/T cell lymphoma undergoing radiotherapy were divided into <50 Gy group(n=20), 51-60 Gy group(n=24) and ＞60 Gy group(n=20), all groups were observed and their local control rate and survival rate of 5 years were compared. Results The total local control rates in the three groups were 68.5%, 82.5% and 72.2% respectively. There was significant difference in the local control rate and survival rate of 5 years between＜50 Gy group and the other two groups (51-60 Gy and ＞60 Gy group) (P＜0.05), but the differences between the two groups were not statistically significant. Conclusions 51-60 Gy doses of radiation can guarantee good local control rate, improve overall survival rate. The choice of radiation doses to 50 Gy in patients with early stage nasal NK/T cell lymphoma is appropriate, with clinical recommendations.
