Second-line treatment of advanced gastric cancer with oxaliplatin plus raltitrexed

BACKGROUND: Treatment with oxaliplatin plus raltitrexed has demonstrated an encouraging therapeutic index in patients with advanced colorectal cancer and malignant pleural mesothelioma. The aim of this multi-institutional study was to determine the antitumor potential of this combination in patients with metastatic gastric cancer failing prior palliative first-line chemotherapy, and to reconfirm its favorable toxicity profile. PATIENTS AND METHODS: 21 patients with metastatic gastric cancer, who progressed while on or within 6 months after discontinuing palliative first-line chemotherapy, participated in this study. They received raltitrexed 3,0 mg/m(2) and oxaliplatin 130 mg/m(2) both given intravenously on day 1 every 3 weeks. RESULTS: One patient achieved a partial response, 6 had stable disease, and 14 patients progressed. Median progression-free and overall survival from the onset of salvage chemotherapy was 2.0 and 4.5 months, respectively. Hematologic adverse reactions, specifically neutropenia and anemia were common, though generally mild to moderate with only 3 patients experiencing grade 3/4 toxicity. The most frequent non-hematologic adverse events included nausea/emesis, asthenia, and transient elevation of liver functional parameters, again with grade 3 symptoms occurring only in a minority of patients. CONCLUSION: Despite reproducibility of a favorable toxicity profile of oxaliplatin + raltitrexed, our data suggest that this combination regimen has no substantial antitumor activity in patients with progressive, chemotherapeutically pretreated metastatic gastric cancer.     

Phase II study of preoperative chemoradiation with S‐1 plus oxaliplatin in patients with locally advanced rectal cancer

A phase II study of preoperative chemoradiation (CRT) with S‐1 plus oxaliplatin in patients with locally advanced rectal cancer was conducted. The total radiotherapy dose was 50.4 Gy. Chemotherapy consisted of oxaliplatin 50 mg/m² on days 1, 8, 22 and 29 and S‐1 80 mg/m² per day on days 1–14 and 22–35. The tumor apparent diffusion coefficient (ADC) was measured using diffusion‐weighted magnetic resonance imaging (DW‐MRI) before and after CRT. Total mesorectal excision was performed within 6 ± 2 weeks. The primary end‐point was the pathological complete response (pCR) rate. A total of 38 patients were enrolled. The pCR rate was 22.9% (8/35; 95% CI, 10.9–42.1), and 10 (28.6%) patients showed near‐total tumor regression. There was no grade 4 adverse event, and grade 3 adverse events included leukopenia (5.4%), diarrhea (5.4%), anorexia (2.7%) and nausea (2.7%). The tumor ADC was calculated in 38 patients (including those who participated in the phase I study). The post‐CRT ADC (P = 0.037) and the percentage change in ADC (P = 0.026) were significantly correlated with pathological response. In conclusion, preoperative CRT with S‐1 plus oxaliplatin showed promising results in pathological responses and favorable toxicity profiles. (Cancer Sci 2013; 104: 111–115)

Multicenter phase II study of docetaxel plus oxaliplatin combination chemotherapy in patients with advanced gastric cancer: Daegu Gyeongbuk Oncology Group

The present study was conducted to evaluate the efficacy and safety of a combination regimen of docetaxel plus oxaliplatin in patients with advanced gastric cancer. Patients with previously untreated metastatic or recurrent, measurable gastric cancer received intravenous docetaxel 65 mg m(-2) plus oxaliplatin 120 mg m(-2) on day 1 based on a 3-week cycle. Forty-two patients were enrolled in the current study, among whom 39 were assessable for efficacy and all assessable for toxicity. One complete response and 18 partial responses were confirmed, giving an overall response rate of 45.2% (95% confidence interval (CI); 31.7-59.7%). At a median follow-up of 7.7 months, the median time to progression and median overall survival was 5.7 (95% CI; 4.3-7.2) months and 9.9 (95% CI; 7.8-12.0) months, respectively. Grade 3/4 neutropenia occurred in 11 patients (26.1%) and febrile neutropenia was observed in four patients (9.5%). The common non-haematologic toxicity was fatigue (grade 1/2, 61.9%) and nausea (grade 1/2, 47.7%). The combination of docetaxel and oxaliplatin was found to be well tolerated and effective in patients with advanced gastric cancer.

A phase II study of capecitabine plus 3-weekly oxaliplatin as first-line therapy for patients with advanced gastric cancer

Capecitabine plus oxaliplatin every 3 weeks (XELOX regimen) has proven efficacy in patients with colorectal carcinoma. We investigated this combination in patients with previously untreated advanced gastric carcinoma. The study population comprised patients with histologically confirmed nonresectable advanced gastric adenocarcinoma. Patients received intravenous oxaliplatin 130 mg m(-2) over 2 h on day 1 plus oral capecitabine 1000 mg m(-2) twice daily on days 1-14, every 3 weeks. Patients received a maximum of eight cycles. Twenty evaluable patients (17 men, 3 women) with a median age of 64 years (range 38-75) were enrolled. The overall response rate was 65% (95% confidence interval (CI), 44-86%), with complete responses in two patients and partial responses in 11 patients. Median progression-free survival was 7.5 months (95% CI, 3.2-11.7 months); median overall survival was not reached during the study period. There was no grade 4 and little grade 3 toxicity. The most common haematological adverse event was anaemia (65% of patients) and the most common nonhaematological toxicities were vomiting (65%), neuropathy (60%), diarrhoea (30%), and hand-foot syndrome (20%). In conclusion, XELOX is apparently as effective as triplet combinations and is well tolerated as first-line therapy for advanced gastric carcinoma. We are starting a large multi-institutional phase II study of XELOX in this setting.
