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

METHODS Advanced cancer patients, all of whom had previously undergone chemotherapy, were randomly divided into 2 groups, one receiving chemotherapy only as the control group, and the other receiving CDA-2 in addition to chemotherapy as the combination group. The therapeutic efficacies and the toxic maniestations of the 2 groups were compared based on the WHO criteria. RESULTS Of 454 cancer patients enrolled in phase Ⅲ clinical trials of CDA-2, 80, 188, and 186 were breast cancer, NSCLC, and primary hepatoma patients, respectively. Among them 378 patients completed treatments according to the protocols. The results showed that the overall effective rate of the combination group was 2.6 fold that of the control group, 4.8 fold in the case of breast cancer, 2.3 fold in the case of primary hepatoma, and 2.2 fold in the case of NSCLC. Surprisingly, the combination therapy appeared to work better for stage Ⅳ than stage Ⅲ patients. CDA-2 did not contribute additional toxicity. On the contrary, it reduced toxic manifestations of chemotherapy, particularly regarding white blood cells, nausea and vomiting. CONCLUSION Modulation of abnormal methylation enzymes by CDA-2 is definitely helpful to supplement chemotherapy. It significantly increased the therapeutic efficacy and reduced the toxic manifestation of cytotoxic chemotherapy on breast cancer and NSCLC.展开更多
