Abstract


Background: Recent studies have demonstrated that hepatectomy in patients with synchronous hepatic gastric metastases may improve survival in certain patients. This study aimed to evaluate survival benefits of gastrectomy plus hepatectomy versus gastrectomy alone in patients with hepatic gastric metastases.

Methods: Studies were identified by a systematic search of Embase, PubMed, Cochrane Library, and Google Scholar databases. Traditional and cumulative meta-analyses were used to monitor the evidence over time.

Results: Eleven studies which included 861 patients compared gastrectomy plus hepatic resection in 349 patients with gastrectomy alone in 512 patients. Overall significantly better survival rates of 1, 2, 3, and 5 years were demonstrated for patients who underwent gastrectomy plus hepatic resection compared to patients who under underwent gastrectomy alone ((hazard ratio (HR) = 0.52 (0.39, 0.69), P < 0.001), (HR = 0.85 (0.74, 0.97), P = 0.01), (HR = 0.80 (0.72, 0.90), P = 0.003), (HR = 0.83 (0.78, 0.90), P < 0.001), respectively).

Conclusions: Carefully selected patients with hepatic gastric metastases may benefit from hepatic resection.
