A tailored regimen including capecitabine and oxaliplatin for treating elderly patients with metastatic colorectal carcinoma Southern Italy Cooperative Oncology Group trial 0108.
From September 2001 to November 2002, 35 patients aged 70-81 (median, 75) years, with measurable metastatic lesions from colorectal carcinoma, were treated with a combination of oxaliplatin (OXA) infused i.v. over 2 h on day 1, and capecitabine, assumed orally twice a day (12-h apart) from day 2 to day 15. An alternated dose escalation for both drugs was planned over the first three cycles for each patient, in the absence of WHO grade > or =2 toxicity on previous cycle: starting doses were 85 mg/m2 for OXA, and 2000 mg/m2 (day) for capecitabine on first cycle; on second cycle, OXA was planned at 100mg/m2, while capecitabine was planned at 2500 mg/(m2 day) on third cycle. Treatment was repeated every 3 weeks until progression, or for a maximum of 12 cycles. A total of 212 cycles were administered, with a median of 6 (range, 1-12) cycles/patient. Dose escalation was performed in 18 (51%) patients for OXA, and in 4 (11%) patients for capecitabine. No grade 4, and 10 (29%) cases of grade 3 toxicity of any type were reported. Abdominal symptoms (pain, nausea, or vomiting) affected 66% of patients, but they were of grade 3 in only 2 (6%) patients. Grade 3 diarrhoea occurred in 3 (9%) patients. Two complete and 12 partial responses (PR) were reported, for an overall response rate of 40% (95% CI, 24-58%). Progression of disease occurred in 23 (66%) patients, and 18 (51%) died. The actuarial median progression-free and survival time were 6.9 and 14.1 months, respectively.
