Laparoscopy-assisted gastrectomy in the elderly: experience from a UK centre

Evaluation of Peroperative and Oncological Results in Laparoscopic Surgery of Gastric Cancer in Elderly Patients: Single-Center Study

Introduction: Laparoscopic treatment of gastric cancer in elderly patients is still controversial. The aim of this retrospective study is to evaluate the safety and feasibility of laparoscopic gastrectomy in elderly gastric cancer patients based on the long- and short-term results of laparoscopic surgery. Materials and Methods: The data of 163 patients who underwent laparoscopic gastrectomy for gastric cancer. Patients were categorized into two groups by age based on World Health Organization (WHO) criteria: elderly (≥65 years, 80 cases) and nonelderly (<65 years, 83 cases). Patient characteristics and clinicopathological findings, surgical findings, short- and long-term results were compared between the two groups. Results: The patients in the study group were in the age range of 22-87 years and 80 (49%) patients were found out to be 65 years old or older. When all complications were categorized according to Clavien-Dindo (C-D) classification, >3 serious complication rates were similar between groups (P = .421). Although the length of hospital stay and the need for intensive care were higher in the elderly group, the difference was not significant (P = .066; P = .072). There was no significant difference between the two in terms of in-hospital mortality (P = .364). No statistically significant differences were found in the rates of overall survival (nonelderly group; 61.17 ± 3.34, 95% confidence interval [CI]: 54.61-67.74 versus elderly group; 56.48 ± 3.80, 95% CI: 49.03-63.93; P = .176) and disease-specific survival (nonelderly group; 64.24 ± 3.15, 95% CI: 58.06-70.40 versus elderly group; 61.93 ± 3.57, 95% CI: 54.93-68.93; P = .363) between the age groups. Conclusion: In conclusion, although laparoscopic gastrectomy is a feasible and safe method in elderly gastric cancer patients, further randomized prospective studies are needed.

Safety and feasibility of laparoscopic gastrectomy accompanied by D1+ lymph node dissection for early gastric cancer in elderly patients

INTRODUCTION

The age of patients with gastric cancer has increased worldwide. The aim of this study was to investigate the safety and feasibility of laparoscopic gastrectomy (LG) for early gastric cancer in elderly patients.

METHODS

We retrospectively investigated 221 consecutive patients who underwent LG for early gastric cancer during a 5-year period (January 2010 to December 2014). We divided the patients into two groups: elderly patients (≥75 years old) and younger patients (<75 years old). We compared these two groups with respect to clinical characteristics, histopathological findings, intraoperative factors, and postoperative outcomes.

RESULTS

The preoperative characteristics were similar in both groups. Except for the number of harvested lymph nodes (42.0 vs 34.9; P = 0.0016), the short-term operative outcomes, including postoperative complications and histopathological findings, were comparable between the two groups. Although significantly fewer lymph nodes were harvested in the elderly group, the overall survival and relapse-free survival rates did not significantly differ between the groups. Postoperative complications, such as acute cholecystitis and internal hernia, occurred during the long-term postoperative period after LG, and these unexpected complications were more frequently observed in elderly patients. All elderly patients required additional emergent surgeries for delayed complications.

CONCLUSION

The outcomes of LG for early gastric cancer in elderly patients seem to be reasonable. Aggressive lymph node dissection may be omissible in elderly patients with acceptable results. LG can be a safe and feasible procedure in elderly patients. However, the higher rate of delayed but urgent complications during the long-term postoperative period must be considered.

Outcomes of Laparoscopic Total Gastrectomy for Elderly Gastric Cancer Patients

Purpose: The purpose of this study was to compare the short- and long-term outcomes after laparoscopic total gastrectomy (LTG) between elderly and non-elderly patients with gastric cancer.

Methods: A retrospective analysis was performed using clinical and follow-up data from 168 patients treated with LTG for gastric cancer at our institution from January 2010 to December 2017. For this study, the short- and long-term outcomes (including tumor recurrence rate, disease-free survival rate, and overall survival rate) were compared between the elderly group (≥70 years) and non-elderly group (<70 years).

Results: The preoperative American Society of Anesthesiologists score and Charlson Comorbidity Index were higher in the elderly group than in the non-elderly group, while there was no significant difference between the two groups in terms of operation duration, intraoperative blood loss, and rate of conversion to laparotomy. The incidence of postoperative 30-day complications in the elderly group was higher than that in the non-elderly group due to a higher incidence of pulmonary infection, while the incidence of major complications was similar in both groups. The tumor recurrence rate was also similar in both groups. There was no statistically significant difference between the two groups in terms of 5-year disease-free survival and 5-year overall survival rate.

Conclusions: LTG is safe and feasible for elderly patients with gastric cancer and is associated with relatively good long-term outcomes.
