We aimed to compare CHOP plus rituximab （R-CHOP） with CHOP alone and determine the value of radiotherapy in these patients. Methods： Between 2003 and 2009, 140 untreated patients with stage I DLBCL were retrospectively analyzed in this study. Results： Seventy-eight patients were treated in R-CHOP group and 62 in CHOP group. Ninety-one patients received additional radiotherapy at the end of chemotherapy. The different treatment groups were well-balanced with respect to baseline characteristics. Complete response （CR） rate was 77% both in R-CHOP and CHOP groups （P=0.945）. After a median follow-up period of 56 months, patients received R-CHOP regimen had similar 5-year progression-free survival （PFS） （76% vs. 85%; log-rank P=0.215） and 5-year overall survival （OS） （90% vs. 96%; log-rank P=0.175） compared with those with CHOP alone. Patients with radiotherapy had significantly increased 5-year PFS compared with those who had chemotherapy alone （86% vs. 71%; log-rank P=0.005）. At multivariate analysis, patients who had CR （P=0.008） and received radiotherapy （P=0.003） were significantly associated with superior PFS. Conclusions： CHOP alone could be as effective as R-CHOP regimen and additional radiotherapy would be necessary for stage I or stage I non-bulky DLBCL patients.展开更多
