ABSTRACT
Background and purpose:Although there is still no standard ifrst line chemotherapy regimen for metastatic gastric cancer (MGC), the doublet and triplet regimens containing platinum and lfuorouracil were most popular worldwidely. The ECF regimen is the classical and one of the most popular treatment choices in this setting, while the marrow suppression, the renal toxicity and poor compliance inhibits its usage. In order to improve its efifcacy and tolerability, this study conducted 2 phaseⅡ trials by modified ECF regimen, the EOF5 regimen (substituting cisplatin with oxaliplatin, shortening the continuous infusion period to 120 h), to treat patients with MGC since 2004. This paper reported the comprehensive results of the 2 studies.Methods:All the patients who enrolled in our previous2 phaseⅡ trials and received EOF5 as ifrst line treatment entered this study. Each patient received the treatment of epirubicin 50 mg/m2 iv d1, oxaliplatin 130 mg/m2 iv gtt d1 and 5-FU 375-425 mg/m2·d-1 civ 120 h, and repeated every 3 weeks. Efifcacy was analyzed every 6 weeks.Results:A total number of 178 patients (all were metastatic patients but 2 advanced patients with unresectable lesions) were included into this study. One hundred and seventy patients were evaluable, and 7 patients (3.9%) achieved complete response (CR), 76 patients (42.7%) achieved partial response (PR), 46.6% patients achieved overall response rate (ORR, CR+PR), and the cases of stable disease (SD) and progressive disease (PD) were 69 (38.8%) and 18 (10.1%), respectively. The median progress free survival (PFS) and overall survival (OS) were 6.0 months (95%CI: 5.2-6.8) and 12.6 months (95%CI: 8.9-16.3), 1-year and 2-year survival rate were 50.9% and 28.0%, respectively. Grade 3, 4 toxicity including: leucopenia (23.0), neutropenia (38.8%), anemia (6.5%), thrombocytopenia (23.5%), nausea/vomiting (14.1%), and peripheral neuropathy toxicity (1.2%). Among 75 patients who received second line treatment, the median survival from second line treatment was 8.0 months (95%CI: 4.8-11.2).Conclusion:EOF5 regimen is a highly effective regimen with moderate and manageable toxicity, and it providesa suitable alternative for the ifrst-line treatment of MGC.
ABSTRACT
Background and purpose: Paclitaxel is believed to be efficient in treating malignant ascites in gastric cancer. However, researches are still needed to get more evidence. The aim of this study was to discuss the efficacy and safety of the treatment of malignant ascites in gastric cancer with paclitaxel. Methods: Six cases of late phase gastric cancer patients were enrolled into the study, paclitaxel 60 mg/m~2 and 1 500-2 000 mL natural solution were administered via intraperitoneal injection, qw, for a of total 2-4 weeks. Efficacy and toxicity were determined according to WHO criteria. Results: Five (5/6) had complete response, and one (1/6) with partial response. The malignant ascites recession time was 0.5-10 months, overall survival time 2-10 months, 4 cases suffered grade Ⅰ-Ⅲabdominal pain, 4 cases grade Ⅰ leucopenia, 3 cases grade Ⅰ hair loss, 1 case grade Ⅰ liver injury (with past history of hepatitis). Conclusion: Paclitaxel is effective and relatively safe to treat malignant ascites of gastric cancer.
ABSTRACT
Purpose:To investigate the efficacy and adverse effects of irinotecan, a novel and potent inhibitor of topoisomerase Ⅰ, for second line treatment of advanced colorectal cancer.Methods:14 patients who previously failed with fluorouracil treatment received single drug irinotecan 300 mg/m 2 intravenously every 3 weeks . All patients had received adjuvant therapy containing fluorouracil. Two patients had received pelvic radiotherapy.Results:Nine patients had received three cycles and five patients completed six cycles . Ten cases had stable disease, and four with progressive disease were observed among the 14 patients. The common treatment related adverse events were cholinergic syndrome (92.9%) ,delayed diarrhea (78.6%) and neutropenia (78.6%) . Grade Ⅲ side effects occurred in several patients: two nausea/ vomiting , two delayed diarrhea and one neutropenia / leucytopenia . Only one patient developed grade Ⅳ diarrhea.Conclusions: Irinotecan is an active drug in the treatment of advanced colorectal cancer with acceptable toxicity.

ABSTRACT
Purpose:To investigate the efficacy and safety of docetaxel and two docetaxel plus cisplatin regimens in patients with non-small-cell lung cancer (NSCLC).Methods:Patients with NSCLC were randomly assigned to receive single-agent docetaxel (AISU) every 3 weeks (A);docetaxel (AISU) 75 mg/m 2 plus cisplatin 75 mg/m 2 every 3 weeks (B);docetaxel (Taxotere) 75 mg/m 2 plus cisplatin 75 mg/m 2 every 3 weeks (C). Results:104 of 115 patients were evaluable for efficacy. Overall response rates of A,B and C were 8.10%,23.53% and 27.27%, respectively. Response with B was similar to C. The major toxicities were neutropenia,anemia,febrile neutropenia,fever,alopecia,nausea,vomiting and fatigue. Neutropenia was more common with C than with B ( P
ABSTRACT
Purpose:To evaluate the efficacy and toxicity of combination of MabThera and CEOP regimen in the treatment of aggressive B-cell lymphoma. Methods:21 patients diagnosed as aggressive B-cell lymphoma with median age of 48 years old (from 15 to 68 years old),received the treatment of MabThera plus CEOP regimen. This treatment consisted of MabThera 375 mg/m2 intravenously infusion on day 1,cyclophosphamide 750 mg/m 2 ,epirubicin 60 mg/m 2 ,vincristine 2 mg on day3 ,prednisone 40 mg/m 2 orally taken on day 3～7. Results:In all 21 patients,16 (76.2%) complete response and 3 (14.2%) partial response were observed. Thus,the overall response rate was 90.5%. Moreover,of the remaining patients,1(4.8%) achieved stable disease and 1(4.8%) had progressive disease. In the 19 responsive patients,the follow-up duration were from 2 to 15 months. One case of thyroid lymphoma experienced recurrence after 14 months with complete response. Until now,the other responses have been maintained. Only one dose of MabThera infusion related-toxicity was observed in all who received 87 cycles. The hematological toxicities were mainly leucopenia and neutropenia. 5( 23.8% ) experienced 3-4 grade neutropenia. Only 1 patient developed neutropenia fever. The other non-hematological toxicities were 1-2 grade except grade 3 alopecia. Conclusions:The combination of MabThera and CEOP regimen had high efficacy with mild toxicity in the treatment of aggressive B-cell lymphoma,hopefully may become the standard treatment.
