Clinical Trial
Phase II study of weekly irinotecan (CPT-11) as second-line treatment of patients with advanced colorectal cancer.
This phase II trial studied the antitumor effect and toxicity of weekly irinotecan (CPT-11, 125 mg/m(2) 60 min iv infusion, weekly for 4 wk plus 2 wk rest) as second-line chemotherapy in patients with advanced colorectal cancer (CRC) resistant or refractory to prior 5-fluorouracil (5-FU) therapy. Sixty-nine patients with adenocarcinoma (57% in the colon and 43% in the rectum) were enrolled. The median number of treatment cycles received per patient was 4 (range, 1-6). ⋯ No febrile neutropenia or infection was documented. Grade 3/4 nausea and vomiting were reported in 1 (1.4%) and 7 patients (10.1%), respectively. In conclusion, this phase II trial showed a response rate and a toxicity profile of weekly CPT-11 in line with the results of prior phase II studies.
