Background and aim
We investigated the clinical benefits of salvage gastrectomy for stage IV gastric cancer patients whose distant lesions showed complete response after chemotherapy.
Methods
We enrolled 18 stage IV gastric cancer patients whose distant metastases had disappeared or were controlled by a combination of biweekly paclitaxel (PTX) and S-1. After chemotherapy, these patients received gastrectomy with lymph node dissection. The postoperative outcome was analyzed with respect to both the histological effects of chemotherapy and tumor behavior.
Results
Of the 18 patients, 8 had distant lymph node metastases, 9 had peritoneal dissemination, and five had multiple liver metastases prior to chemotherapy. Fourteen patients received curative surgery (R0). No severe postoperative complications were encountered. Pathological evaluation revealed grade 3 and grade 2 tumor regression in the primary lesion in one and five patients, respectively, and grade 3 and grade 2 tumor regression in the lymph nodes in one and six patients, respectively. Univariate analysis of the patients’ prognosis identified R number, gross tumor type, histological grade of tumor regression, and gender as significant factors. Multivariate analysis showed that only the R number was an independent prognostic factor.
Conclusion
R0 salvage gastrectomy following a combination of biweekly PTX and S-1 may have significant clinical efficacy for advanced gastric cancer patients.
