[Efficacy and safety of combination of irinotecan and capecitabine in patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin].
OBJECTIVE
To evaluate the efficacy and safety of irinotecan combined with xeloda (CAPIRI regimen) in patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin.


METHODS
Totally 38 patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin were enrolled. Patients received xeloda 1 000 mg/m2 orally twice daily on day 1 to 14 and intravenous irinotecan 100 mg/m2 on day 1 and 8 every 3 weeks.


RESULTS
The median age of 38 patients was 58.5 (27-77) years. CAPIRI regimen was used 11.0 (3.0-24.0) months after the diagnosis of metastatic colorectal cancer (CAPIRI regimen as second-line chemotherapy in 33 patients, third-line in 4 patients, and fourth-line in 1 patient). A total of 121 cycles of chemotherapy (median 3.0) were administered. Thirty-four patients were evaluable for response. The overall response rate and disease control rate were 5.9% and 61.8%, respectively. The median time to progression and overall survival were 4.5 months (95% CI, 3.4-5.6 months) and 11.0 months (95% CI, 10.2-11.8 months), respectively. All 38 patients were evaluable for safety. The most common adverse events were leukopenia (73.7%), neutropenia (65.8%), nausea and vomiting (60.5%), and diarrhea (28.9%). The occurrence rates of these grade 3-4 events were 10.5%, 13.2%, 10.5%, and 7.9%, respectively. All adverse events were tolerable.


CONCLUSIONS
CAPIRI regimen is effective and well-tolerated in Chinese patients with metastatic colorectal cancer after failure of chemotherapy with oxaliplatin.
