Prognostic factors for gastrectomy in elderly patients

Area of Science:

• Geriatric Surgery
• Surgical Oncology
• Gastrointestinal Oncology

Background:

• Gastric cancer surgery in octogenarians (patients aged ≥85 years) presents unique challenges.
• Careful preoperative assessment is crucial for this age group.
• Limited data exists on prognostic factors for gastrectomy in the very elderly.

Purpose of the Study:

• To identify prognostic factors influencing survival after curative gastrectomy in patients aged ≥85 years.
• To analyze the impact of clinical characteristics and surgical extent on patient outcomes.
• To determine independent predictors of overall and pneumonia-specific survival.

Main Methods:

• Retrospective review of 64 patients aged ≥85 years who underwent curative gastrectomy for gastric cancer.
• Analysis of clinical characteristics, surgical interventions (gastric resection extent, lymph node dissection), and blood loss.
• Univariate and multivariate statistical analyses to identify significant prognostic factors.

Main Results:

• Univariate analysis identified sex, extent of gastric resection, lymph node dissection extent, and blood loss as significant prognostic factors for overall survival.
• Multivariate analysis revealed sex as the sole independent prognostic factor for overall survival.
• Sex was also the only independent prognostic factor for pneumonia-specific survival.

Conclusions:

• Male sex is associated with a significantly worse prognosis after gastrectomy in patients aged ≥85 years compared to females.
• Males are more susceptible to pneumonia-related mortality post-gastrectomy.
• Sex-specific considerations are vital when deciding on surgical management for very elderly gastric cancer patients.
