[Prevention of postoperative recurrence after hepatic resection for metastatic colorectal cancer by adjuvant locoregional chemotherapy].

Postoperative adjuvant locoregional chemotherapy was performed on patients who underwent hepatic resection for metastatic colorectal cancer. To prevent recurrence in the residual liver after hepatic resection. 7 patients received intra-hepato-arterial infusion of MMC, 5-fluorouracil (5-FU), doxorubicin + Lipiodol emulsion. Sixteen cases did not receive such treatment. The 1-, 2- and 3-year cumulative disease free rates were 100, 80 and 40% in the patients with this adjuvant chemotherapy, against 61.4, 54.6 and 28.1% in those without this locoregional therapy, respectively. The 1-, 2- and 3-year cumulative survival rates were 100, 100 and 60% in the TAI-E group, and 73.7, 63.3 and 63.3% in the patients without TAI-E, respectively. Postoperative adjuvant locoregional chemotherapy is considered effective to prevent the recurrence of metastatic colorectal cancer in the residual liver after hepatectomy.
