Response to Preoperative Chemotherapy Predicts Survival in Patients Undergoing Hepatectomy for Liver Metastases from Gastric and Esophageal Cancer

Background The role of hepatectomy for patients with liver metastases from gastric and esophageal cancer (GELM) is not well defined. The present study examined the morbidity, mortality, and long-term survivals after liver resection for GELM. Methods Clinicopathological data of patients who underwent hepatectomy for GELM between 1995 and 2012 at two European high-volume hepatobiliary centers were assessed, and predictors of overall survival (OS) were identified. In addition, the impact of preoperative chemotherapy for GELM on OS was evaluated. Results Forty-seven patients underwent hepatectomy for GELM. The primary tumor was located in the stomach, cardia, and distal esophagus in 27, 16, and 4 cases, respectively. Twenty patients received preoperative chemotherapy before hepatectomy. After a median follow-up time of 76 months, 1-, 3-, and 5-year OS rates were 70, 37, and 24 %, respectively. Postoperative morbidity and mortality rates were 32 and 4 %, respectively. Outcomes were comparable between the two centers. Preoperative chemotherapy for GELM (5-year OS: 45 vs 9 %, P = .005) and the lack of posthepatectomy complications (5-year OS: 34 vs 0 %, P
