Prognostic factors for survival in patients with hepatic recurrence after curative resection of gastric cancer



Prognostic factors for survival in patients with hepatic recurrence after curative resection of gastric cancer



World Journal of Surgery 33(7): 1468-1472



This study was done to evaluate the prognostic factors that may affect the survival of patients with recurrent hepatic metastasis after curative resection of gastric cancer. We reviewed the medical records of 73 patients with recurrent hepatic metastasis after surgical treatment of gastric cancer from January 1995 to December 2005. Prognostic factors were classified into three groups: primary tumor factors, recurrent hepatic factors, and treatment factors. The prognostic values of these factors were assessed using univariate and multivariate analyses by the log-rank test in the Kaplan-Meier method and Cox's proportional hazard model. The overall median survival rate of the 73 study patients was 20.0 months [95% confidence interval (CI) 15.4-24.6 months]. The median survival rate after diagnosis of recurrent hepatic metastasis was 5 months (95% CI 3.5-6.5 months). Univariate analysis showed that the favorable prognostic factors were stage I and II among the primary tumor factors, no extrahepatic metastasis and unilobar distribution among the recurrent hepatic factors, and radiofrequency ablation (RFA) +/- chemotherapy among the treatment factors when operative treatment had been excluded. The independent favorable prognostic factors revealed by the multivariate analysis were no extrahepatic metastasis and RFA +/- chemotherapy. The median survival rate of patients who had two favorable prognostic factors was 27 months (95% CI 0-66.38 months). Improvement in the survival rate can be expected with RFA +/- chemotherapy for patients with recurrent gastric cancer in the liver without extrahepatic metastasis.
