Objective:
To explore the efficacy and safety of CPT-11 combined with fluoropyrimidine in treatment for advanced or metastatic colorectal carcinoma.
Methods:
From January 2001 to September 2003, 43 patients with advanced or metastatic colorectal carcinoma were randomized into two groups, group A [CPT-11 90 - 25 mg/m(2) continuous infusion for 10 h and folinic acid (FA) 30 mg x m(-2) x d(-1) + 5-FU 425 mg x m(-2) x d(-1) x 2 d continuous infusion for 48 h, every two weeks as a cycle in total of no less than six cycles] and group B (CPT-11 90 - 125 mg/m(2) continuous infusion for 10 h every two weeks as a cycle in total of no less than six cycles and capecitabine 1250 mg x m(-2) x d(-1) by oral divided into two doses, continuously taken without interruption for three months).
Results:
In this study, overall response rate (ORR) was 44.2%, disease control achieved in 83.7%, Time to progression (TTP) was 11.0 months and overall survival (OS) was 14.6 months. Response rate in group A was 31.3% and 51.9% in group B. TTP of group A was 8.4 months and that of group B was 12.5 months; OS in group A was 14.2 months and 17.9 months in group B. In 43 cases with 502 cycles of chemotherapy, grade III side effect occurred only in 3.0% and no therapy-related death occurred. Nausea and vomiting was the most common side effect with an occurrence rate of 31.9% in group A and 2 cases of grade III, and 22.7% in group B with no case of grade III. Occurrence of side effect was much lower in group B than that of group A except hand-foot syndrome, which was 16.1% in group B with 2 cases of grade III as compared to 1.4% in group A with no case of grade III.
Conclusions:
Combination of CPT-11 and fluoropyrimidine is effective and safe in treatment for advanced/metastatic colorectal carcinoma. CPT-11 combined with capecitabine are not only more effective, but also its occurrence of side effect is lowered, and are especially high effective for lung metastasis. There is reasonable to recommend that combination of CPT-11 with capecitabine may be as first choice in treatment for such cases.
