Methods： A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed. Results： During a median follow-up period of 39.8 months （5.4-93.0 months）, the median progression-free survival （PFS） was 26.2 months （95% CI：0-65 months） and the 3-year overall survival （OS） rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage （stage Ⅰ/Ⅱ）, lactate dehydrogenase （LDH） ≤245 U/L, international prognostic index （IPI） ≤1, primary tumor diameter 〈7.5 cm, and patients who had complete response （CR） and received doxoruhicin-contained chemotherapy （P〈0.05）. There was a trend toward superior outcome for patients who received combined therapy （surgery/ chemotherapy/radiotherapy） （P=0.055）. Patients who had CR, primary tumor diameter 〈7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis. Conclusions： Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy （RT） seemed to improve survival.展开更多

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
