Abstract:
Objective To compare the efficacy and side effects between systemic chemotherapy and hepatic arterial infusion by combination of oxaliplatin and 5-fluorouracil (FOLFOX-6) with 5-fluorouracil in the patients who have developed hepatic metastasis after colorectal cancer operation. The factors that would affect the prognosis without operational treatment were also analyzed. Methods 46patients who had signed the informed consents were allocated into two groups: the group with general chemotherapy (Trial Group includes 26 cases) and the one with hepatic arterial infusion chemotherapy (Control Group includes 20 cases). The total effective rate, the prognosis, the cytoxicitic side effects,quality of life, the total survival rate and the responses were the main parameters determined. Kaplan-Meier was used to analyze Mono-factor to the prognostic responses and the Cox mode was used to analyze poly-factor to the prognostic responses. Results The overall survival rate was significantly higher by using systemic treatment versus HAI(median, 15. 0 v 11.2 months;P＜0.05). The difference in overall responsive rate (CR+PR) between the two groups was statistically significant (50% v 10%;P=0. 011). No significant difference was found in PS scale during the treatment. (P=0. 126). Except for myelosuppression and abdominal pain, no significant difference was found in the other side effects. Univariate analysis revealed that the invasive lesions to serosa, the distribution of liver metastases, the size and number of liver metastases, primary carcinoma involving lymph nodes and the treatment were correlated with prognoses. Cox regression analysis showed that the larger diameter of liver metastases, the number of liver lesions, primary carcinomas involved in serosal layer and the treatment modules were independent prognostic factors. Conclusions The oxaliplatin-based FOLFOX-6 chemotherapy regiment has a better responsive rate and survival rate than the traditional infusion with 5-fluorouracil to the main hepatic artery for interventional therapy. The diameter of the hepatic metastasis larger than 5em, multiple hepatic metastasis and the primary lesions penetrating serosal layer suggest the poor prognosis. The oxaliplatin-based systematic chemotherapy has a better prognosis. Therefore,it is worth carrying on further study on modification of traditional hepatic arterial infusion and on evaluation of therapy by combination of the hepatic arterial infusion with the systematic chemotherapy.
