Second-Line Treatment of Advanced Colorectal Cancer with a Biweekly Oxaliplatin plus Irinotecan Combination Regimen

BACKGROUND: Both oxaliplatin and irinotecan have demonstrated antitumor activity in pretreated colorectal cancer; experimental and early clinical data suggest that these two drugs may act synergistically. The aim of this study was to document the therapeutic index of a biweekly combination regimen in patients with metastatic colorectal cancer failing prior palliative first-line chemotherapy with raltitrexed. PATIENTS AND METHODS: In this study 27 patients with metastatic colorectal cancer were analyzed, who progressed while on or within 6 months after discontinuation of palliative first-line chemotherapy with raltitrexed. They received oxaliplatin 85 mg/m(2) and irinotecan 150 mg/m(2) both given on days 1 and 15 every 4 weeks. RESULTS: The confirmed overall response rate was 37% (95% confidence interval, 19.4-57.7%), including 2 complete and 8 partial remissions. 12 additional patients (44.4%) had stable disease, and in only 5 cases (18.5%) disease progression was not influenced by chemotherapy. The median progression-free survival for all 27 patients was 8 months (range, 1-16+ months), and 16 patients (59%) are still alive after a median follow-up time of 12.5 months. Hematologic adverse reactions, specifically leukocytopenia and neutropenia, were common though generally mild to moderate with grade 4 toxicity occurring in only 2 cases. The most frequent non-hematologic adverse events included gastrointestinal symptoms; severe nausea/emesis and diarrhea, however, were noted in only 2 and 3 patients, respectively. CONCLUSIONS: Our data suggest that the described biweekly combination regimen of oxaliplatin and irinotecan has substantial antitumor activity in patients with progressive, raltitrexed-pretreated metastatic colorectal cancer. Because of its favorable toxicity profile, further evaluation of this combination seems warranted.     

Clinical observation of raltitrexed/bevacizumab combined with irinotecan or oxaliplation for advanced colorectal cancer简

Objective： The aim of the study was to investigate the efficacy and safety of raltitrexed/bevacizumab in combination with irinotecan or oxaliplation for advanced colorectal cancer as the second-line and second-line above treatments. Metho ods： Fifteen cases of advanced colorectal cancer were enrolled to receive regimens including raltitrexed/bevacizumab combined with irinotecan or oxaliplation. Two cases were treated with raltitrexed ＋ bavacizumab regimen, 9 cases with raltitrexed ＋ bavacizumab ＋ irinotecan regimen, and 4 cases with raltitrexed ＋ bevacizumab ＋ oxaliplation regimen. The doses of the drugs were as follows： bevacizumab 5 mg/kg ivgtt, d 1; raltitrexed 2.0 mg/m2 ivgtt 15 min, d2; irinotecan 180 mg/m2 ivgtt 1 h, d2; and oxaliplatin 85 mg/m2 ivgtt 2 h, d2. Two weeks was a cycle for each regimen. Results： The efficacy of the 15 patients could be evaluated. Two cases were in PR ,10 cases in SD, 3 cases in PD, the response rate was 13.3%, and the disease control rate was 80.0%. The median progress-free survival was 5.1 months （95% CI： 3.404-6.813 months）, and the median overall survival was 11.5 months （95% CI： 8.985-13.930 months）. The adverse effects included anorexia, nausea/vomiting, fatigue, leucopenia, thrombocytopenia, etc, and the main 3-4 grades adverse effects were anorexia, nausea/vomiting, fatigue, and thrombocytopenia. Conclusion： Raltitrexed/bevacizumab combined with irinotecan or oxaliplatin as the secondline and second-line above treatments for advanced colorectal cancer has high disease control rates, and the adverse effect is well tolerated. The combined regimen can be recommended as a phase III clinical research and second-line and secondlines above treatments for advanced colorectal cancer.

Oxaliplatin- or irinotecan-based chemotherapy for metastatic colorectal cancer in the elderly

The tolerance and efficacy of oxaliplatin and irinotecan for metastatic colorectal cancer are unknown in elderly patients. Methods. All consecutive patients over 74 years treated with oxaliplatin or irinotecan for metastatic colorectal cancer were enrolled. The tumour response was assessed every 2-3 months and toxicity was collected at each cycle according to World Health Organisation criteria. A total of 66 patients were enrolled from 12 centres. The median age was 78 years (range, 75-88 years); 39 patients had no severe comorbidity according to the Charlson score. In total, 44 and 22 patients received oxaliplatin or irinotecan, respectively, in combination with 5-fluororuracil+/-folinic acid or raltitrexed in 64 patients. A total of 545 chemotherapy cycles were administered in first (41%), second (51%) or third line (8%). A dose reduction occurred in 190 cycles (35%). Complete response, partial response and stabilisation occurred in 1.5, 20 and 47% of patients, respectively. The median time to progression and overall survival were 6.8 and 11.2 months in first line and 6.3 and 11.6 months in second line, respectively. Grade 3 and 4 toxicity occurred in 42% of patients: neutropenia 17%, diarrhoea 15%, neuropathy 11%, nausea and vomiting 8% and thrombopenia 6%. There was no treatment-related death. In selected elderly patients, chemotherapy with oxaliplatin or irinotecan is feasible with manageable toxicity.     

Second-line treatment with oxaliplatin + raltitrexed in patients with advanced colorectal cancer failing fluoropyrimidine/leucovorin-based chemotherapy

Background:To evaluate the efficacy and tolerance of combined raltitrexed and oxaliplatin in patients with advanced colorectal cancer pretreated with fluoropyrimidine–leucovorin-based chemotherapy. Patients and methods:Thirty-six patients with metastatic colorectal cancer, who progressed while receiving or within six months after withholding palliative chemotherapy with fluoropyrimidines–leucovorin ± irinotecan, participated in this study. Treatment consisted of oxaliplatin 130 mg/m² and raltitrexed 3.0 mg/m² both given on day 1 every three weeks for a total of eight courses unless prior evidence of progressive disease. Results:The overall objective response rate was 33.3% for all 36 evaluable patients (95% confidence interval (CI): 18.6%–51%). Seventeen additional patients (47.2%) had stable disease, and only seven (19.5%) progressed. The median progression-free survival was 6.5 months (range 1.2–14.0). After a median follow-up time of 12 months, 23 patients (63.8%) are still alive. The tolerance of treatment was acceptable with only 8 of 36 patients (22%) experiencing grade 3 or 4 neutropenia. Grade 3 non-haematological adverse reactions included peripheral sensory neuropathy in three, asthenia in one, diarrhea in two, and clinically insignificant increase in serum transaminases in two patients, respectively. Conclusions:Our data suggest that the combination of oxaliplatin and raltitrexed has substantial antitumour activity in patients with progressive fluoropyrimidine–leucovorin ± irinotecan pretreated colorectal cancer. Because of its favorable toxicity profile and convenient three-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.
