Background/aims: Baseline serum lactate dehydrogenase (LDH) level is a well-known prognostic factor in patients with non-Hodgkin's lymphoma; however, its role beyond initial diagnosis has not yet been defined., Methods: This study was conducted as a retrospective analysis of patients with diffuse large B cell lymphoma (DLBCL) treated with R-CHOP21, who had undergone regular checks for LDH during immunochemotherapy (n = 119) and during the posttreatment follow-up period after complete remission (CR; n = 100). The 119 patients were classified into 4 groups according to their baseline and change in LDH level during treatment, and an analysis of tumor response and survival was performed. The value of LDH as a predictor for relapse was evaluated among the patients with regular follow-up visits after achieving CR., Results: An increased LDH level during immunochemotherapy had no impact on tumor response or survival, and only the LDH status 'before' treatment was a prognostic marker. The sensitivity, specificity, positive predictive value and negative predictive value of serum LDH for detecting relapse after CR were 47.4, 86.5, 9.3 and 98.3%, respectively., Conclusion: The measurement of LDH level beyond initial diagnosis has no clear benefit in predicting disease progression or relapse in patients with DLBCL treated with R-CHOP21., (Copyright © 2013 S.

Objectives: The purpose of this study was to evaluate the antitumor activity and safety of an epirubicin, cisplatin, and capecitabine (ECX) combination in patients with metastatic or advanced gastric cancer., Patients and Methods: Patients with metastatic or advanced measurable gastric adenocarcinoma received ECX combination chemotherapy. Epirubicin 50 mg/m2 and cisplatin 60 mg/m2 were administered on day 1 by intravenous injection. Capecitabine 1,000 mg/m2 twice daily was administered orally on day 1-14. The cycle was repeated every 3 weeks., Results: Fifty-four patients were enrolled in this study. Fifty patients were assessable for responses and 53 for toxicity. A total of 250 cycles were administered. The overall best response rate by intent-to-treat analysis was 59% including 52% partial responses and 7% complete responses. Median response duration and time to progression was 5.8 and 6 months, respectively. Median survival for all patients was 9.6 months (95% CI, 8.7-10.5 months). The most common grade 3/4 hematological adverse event was neutropenia in 31% (76 cycles) including febrile neutropenia in 4.8% (11 cycles). Non-hematological toxicity was generally mild and reversible. Grade 3/4 nausea, vomiting and stomatitis occurred in 8, 9, and 8% of the patients, respectively. Hand-foot skin reactions developed in 51% of patients, but most were self-limited. Grade 3 occurred in only 4%. One patient died of neutropenic sepsis., Conclusions: ECX combination regimen showed high anti-tumor activity with a tolerable toxicity pattern as a front-line chemotherapy for patients with metastatic or advanced gastric cancer., ((c) 2005 S.

Objective: The aim of this study was to evaluate efficacy and safety of the combination chemotherapy with irinotecan plus capecitabine in patients with advanced colorectal adenocarcinoma., Methods: Patients with histologically proven advanced colorectal adenocarcinoma received a first-line chemotherapy with irinotecan 240 mg/m2 on day 1 and capecitabine 2,000 mg/m2/day as an intermittent regimen of 2 weeks of treatment followed by a 1-week rest. Treatment was repeated every 3 weeks., Results: Thirty-nine patients were registered, and 36 were assessable for responses. Sixteen objective responses (44%) were observed with a median response duration of 6.9 months. Stable disease was documented in 14 cases (39%). The median time to progression was 6.7 months. The median overall survival was not reached at the time of analysis, and the 1-year survival rate was 67%. Two patients died: 1 due to sepsis not complicating myelosuppression, and 1 patient, known as a hepatitis B virus carrier prior to chemotherapy, died of hepatic failure, the cause of which was not clinically verified. Frequently encountered therapy-related events were leukopenia and gastrointestinal side effects including diarrhea. Severe hand-and-foot syndrome was observed in only 1 patient., Conclusions: The combination chemotherapy of irinotecan and capecitabine is an active and tolerable regimen for advanced colorectal adenocarcinoma, but the observed deaths suggest a future randomized trial that requires a cautious patient selection.
