Outcomes of laparoscopic gastrectomy for gastric cancer in elderly patients.

Abstract

This study aimed to compare the short- and longterm outcomes of elderly and middle-aged patients with gastric cancer who underwent laparoscopic gastrectomy.From January 2010 to February 2017, a total of 75 patients with gastric cancer aged ≥70 years (elderly group) underwent laparoscopic gastrectomy, and their short- and long-term outcomes were compared with those of 197 patients with gastric cancer aged 60-69 years (middleaged group) who underwent also laparoscopic gastrectomy during the same period.With respect to the patients' preoperative baseline characteristics, the elderly group had a higher Charlson comorbidity index score, rate of previous abdominal operations, and American Society of Anesthesiologists (ASA) classification score compared to middle-aged patient group. There were no significant differences in the other baseline characteristics. There were no significant between-groups differences in the duration of surgery, intraoperative blood loss, incidence and severity of 30-day postoperative complications, and pathological results. Long-term follow-up results showed that the tumor recurrence rates were similar between groups, as were the overall (OS) and disease-free survival (DFS) rates. Multivariate analysis showed that age was not an independent predictor of OS and DFS.In summary, laparoscopic gastrectomy in elderly patients with gastric cancer can achieve similar short- and long-term outcomes as those for middle-aged patients. Age is thus not a contraindication for laparoscopic gastrectomy.
