An alternating regimen of irinotecan/ 5-fluorouracil/folinic acid and oxaliplatin/ 5-fluorouracil/folinic acid in metastatic colorectal cancer: a Phase II trial.

OBJECTIVE: To assess the feasibility and activity of a combination schedule with irinotecan (CPT-11), oxaliplatin (L-OHP), brief infusional fluorouracil (5-FU) and folinic acid (FA) as first-line treatment in metastatic colorectal cancer (MCC) patients. METHODS: Fifty consecutive patients were treated with CPT-11 125 mg/m2 as a 90-min intravenous infusion, followed by FA 20 mg/m2 as an intravenous bolus, and 5-FU 500 mg/m2 over a 2-hour intravenous infusion on days 1 and 8. L-OHP was administered at 85 mg/m2 over 2 h on day 15, in combination with a FA 60 mg/m2 intravenous bolus and 5-FU 600 mg/m2 as a 2-hour intravenous infusion on days 15-16. The treatment was repeated every 4 weeks for a maximum of 9 cycles. RESULTS: Twenty-five of 50 assessable patients achieved a complete (n=5) or partial (n=20) response, leading to a response rate of 50% (95% CI 35-64%). Eighteen (36%) patients showed stable disease. The median time to tumor progression was 10.3 months (95% CI 9.6-10.9 months). After a median follow-up of 16.4 months, the median survival was not reached. Grade 3 neutropenia (8%), grade 3 nausea/vomiting (6%) and grade 3 diarrhea (2%) were the major adverse events. CONCLUSION: This alternating three-drug regimen is very well tolerated, manageable and effective in terms of activity and time to progression.

Gemcitabine plus celecoxib (GECO) in advanced pancreatic cancer: a phase II trial.

INTRODUCTION: Single agent gemcitabine (GEM) is the standard treatment of pancreatic adenocarcinoma. Celecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor. Recent studies in human pancreatic tumor cell lines suggest an involvement of COX-2 in tumor-dependent angiogenesis and provide the rational for inhibition of the COX pathway as an effective therapeutic approach. The aim of this study is to evaluate the toxicity and activity of gemcitabine plus celecoxib. PATIENTS AND METHODS: Forty-two consecutive patients with histologically or cytologically confirmed pancreatic adenocarcinoma entered the trial. Twenty-six patients (pts) were metastatic, 16 pts had locally advanced disease. The schedule consisted of GEM 1,000 mg/m2 (as a 30 min iv infusion) on days 1, 8 every 3 weeks and celecoxib 400 mg bid. RESULTS: Four pts (9%) achieved a partial response and 26 (62%) had stable disease, gaining a total disease control in 30 pts (71% [95% CI, 58-84%]). Overall clinical benefit response was experienced by 23 pts (54.7% [95%CI, 38.6-70.1%]). Neither grade 4 neutropenia nor grade 3-4 thrombocytopenia was observed. Grade 3 neutropenia was detected in 19% of pts. Grade 3 non-hematological toxicity was as follows: hepatic toxicity 7%, nausea 2.3%. Three pts (7%) and 5 pts (12%) had respectively a minimum creatinine increase and edema. Median survival was 9.1 months (95% CI, 7.5-10.6 months). CONCLUSION: GEM in combination with celecoxib showed low toxicity, good clinical benefit rate and good disease control. Further clinical investigation is warranted.

A retrospective series of long-term survivors of metastatic breast cancer in complete remission.

AIM: To describe clinical features, treatment modalities and long-term outcome of patients with overt metastatic breast cancer in complete remission for more than 5 years. PATIENTS AND METHODS: A retrospective survey of 12 patients who were referred to a single institution from 1982 to 1995. RESULTS: The majority of the long-term survivors had a good performance status, endocrine-responsive disease and a single metastatic site. Ten patients had received chemotherapy, 8 patients hormone therapy, and 2 patients had been treated with surgery followed by systemic therapies. At a median follow-up of 11.7 years, 10 of the 12 patients were still in complete remission. The median duration of complete remission was 9.2 years (range 5.0-15.7 years). CONCLUSIONS: This case series confirms that only a few metastatic breast cancer patients could potentially be cured with multidisciplinary treatments.

Epirubicin, cisplatin, and raltitrexed in patients with advanced gastric and hepatobiliary carcinoma: a phase II study.

The combination of epirubicin, cisplatin, and protracted venous-infusion 5-fluorouracil is the standard treatment of advanced gastric carcinoma in many European countries, and it is also an active regimen in hepatobiliary tumors. Raltitrexed is a specific inhibitor of thymidylate synthase with clinical activity in gastrointestinal malignancies. The aim of the study was to evaluate the clinical activity and toxicity of the combination of epirubicin, cisplatin, and raltitrexed in patients with advanced gastric and hepatobiliary tumors. Twenty consecutive patients with gastric carcinoma, 7 with biliary-tract carcinoma, and 5 patients with hepatocarcinoma were treated with epirubicin (60 mg/m2), cisplatin (60 mg/m2) on day 1, and raltitrexed (1 mg/m2) on days 1 and 8, every 3 weeks. The median age was 63 years (range, 28-76). Eight patients had locally advanced disease and 24 had metastatic tumors. Seven of the 18 evaluable patients (39%) with gastric carcinoma and 2 of the 5 patients with hepatocarcinoma have a partial response; 1 minimal response and 4 stabilization of disease were documented in the 7 patients with biliary-tract carcinoma. The median time to progression of the entire group was 6.8 months, and the median survival was 9.0 months. The toxicity was mild and no toxic death occurred. The combination of epirubicin, cisplatin, and raltitrexed, using this schedule, is tolerable and has clinical activity in gastric and hepatobiliary tumors.

Ifosfamide encephalopathy: a case report.

The aim of this short communication is to discuss the mechanism, modality and treatment of ifosfamide encephalopathy. We present the case of a 52-year-old woman treated with this alkylating agent who developed severe neurotoxicity. It was resolved with administration of Methylene blue, abundant intravenous hydration and interruption of ifosfamide.
