Abstract：Objectives To observe the pre and post-operational changes of the expressions of survivin, caspase-3 and CD44V6 in patients with colorectal cancer after intra-abdominal implantation of sustained releasing fluorouracil. Meth-ods Sixty-four patients with colorectal cancer (Dukes’stage of B and C) were divided into treatment group and control group, 32 patients in each group. The standard radical surgery was performed in two groups of patients. The fluorouracil im-plants were implanted intra-abdominally in treatment group. The peripheral blood levels of surviving and caspase-3 were de-tected by RT-PCR. The level of CD44V6 was detected by flow cytometry in two groups of patients. Results There were no significant differences in levels of survivin, caspase-3 and CD44V6 before surgery between two groups (P>0.05). The level of survivin (0.362 ± 0.183) was significantly lower at 14 days after operation in treatment group than that of control group (0.585±0.207), but the level of caspase-3 (2.001±0.146) was significantly higher than that of control group (1.654±0.111). The levels of CD44V6 were significantly lower in treatment group (1.857±0.535) and control group (3.471±0.496) after opera-tion than those before operation (9.557±1.170 and 9.729±0.943, P<0.05), and the level of CD44V6 was significantly lower in treatment group than that of control group (P<0.05). Conclusion The implant for the sustained release of fluorouracil showed a positive impact on micrometastases and prognosis of colorectal cancer, while improved the long-term efficacy of postoperative colorectal cancer.
