Laparoscopic gastrectomy (LG) for advanced gastric cancer (AGC) shows feasible and comparable oncologic outcomes. Postoperative complications are identified as a key risk factor for recurrence-free survival in these patients.

Area of Science:

Surgical Oncology
Gastrointestinal Surgery
Minimally Invasive Surgery

Background:

Laparoscopic gastrectomy (LG) for advanced gastric cancer (AGC) is increasingly utilized but remains controversial.
Evaluating oncologic outcomes and identifying recurrence risk factors after LG in AGC patients is crucial.

Purpose of the Study:

To assess the oncologic outcomes of laparoscopic gastrectomy (LG) in patients with advanced gastric cancer (AGC).
To identify potential risk factors influencing recurrence and survival following LG for AGC.

Main Methods:

Retrospective analysis of medical records of 300 patients who underwent radical LG for histopathologically diagnosed stage IB or higher gastric cancer (2004-2012).
Evaluation of clinicopathologic factors, operative details (median operative time 278 min, blood loss 46 ml), postoperative morbidity (Clavien-Dindo grades III-IV in 6.3%), and survival rates.

Keywords:

Actual survival Advanced gastric cancer Laparoscopic gastrectomy Postoperative complications Prognosis

Main Results:

The 3-year relapse-free survival (RFS) rates varied by stage, from 92.7% (Stage IB) to 43.8% (Stage IIIC).
The 5-year overall survival rates were 91.1% (Stage IB), 72.7% (Stage II), and 62.5% (Stage III).
Multivariate analysis identified postoperative complications as an independent risk factor for RFS.

Conclusions:

Laparoscopic gastrectomy (LG) for advanced gastric cancer (AGC) is a feasible procedure with oncologic outcomes comparable to existing reports.
Postoperative complications significantly correlate with a poorer prognosis in patients undergoing LG for AGC.
Further randomized controlled trials are recommended to validate these findings in a broader patient population.
