Background:
The short- and long-term efficacy of laparoscopic surgery for elderly patients with gastric cancer has not been evaluated. We aimed to use propensity score matching to clarify the efficacy of laparoscopic gastrectomy (LG) for elderly patients with gastric cancer aged ≥80 years.
Methods:
We retrospectively collected data from 159 consecutive patients with gastric cancer aged ≥80 years who underwent gastrectomy with curative intent at our institution between 2004 and 2015. Propensity score matching was applied to compare the open gastrectomy (OG) and LG. Short- and long-term outcomes were evaluated between the propensity-matched groups.
Results:
Patients' backgrounds and surgical factors were similar in both groups except for blood loss. The median time to first flatus was significantly shorter in the LG group than in the OG group (P = 0.002). The postoperative hospital stay was significantly shorter in the LG group (P = 0.014). The complication rate of Clavien-Dindo grade III or higher was significantly lower in the LG group (3% vs. 23%, P = 0.023). The 5-year overall survival and 5-year disease-specific survival rates were better in the LG group than in the OG group, but the differences were not significant (45% vs. 42% and 67% vs 57%, respectively).
Conclusion:
LG was associated with good short-term outcomes and acceptable oncologic outcomes compared with OG in these propensity-matched patients aged ≥80 years.
