Enhancing surgical outcomes in elderly gastric cancer patients: the role of comprehensive preoperative assessment and support.

ABSTRACT

BACKGROUND: As the prevalence of gastric cancer rises in aging populations, managing surgical risks and comorbidities in elderly patients presents a unique challenge. The Comprehensive Preoperative Assessment and Support (CPAS) program, through comprehensive preoperative assessments, aims to mitigate surgical stress and improve outcomes by enhancing patient awareness and preparation. This study investigates the efficacy of a CPAS program, incorporating frailty and sarcopenia evaluations, to improve short-term outcomes in elderly gastric cancer patients. METHODS: A retrospective analysis was conducted on 127 patients aged 75 or older who underwent surgery with CPAS between 2018 and August 2023, compared to 170 historical controls from 2012 to 2017. Propensity score matching balanced both groups based on age-adjusted Charlson Comorbidity Index and surgical details. The primary focus was on the impact of CPAS elements such as rehabilitation, nutrition, psychological support, oral frailty, and social support on short-term surgical outcomes. RESULTS: Among 83 matched pairs, the CPAS group, despite 40.4% of patients in the CPAS group and 21.2% in the control group had an ASA-PS score of 3 or higher (P < 0.001), demonstrated significantly reduced blood loss (100 ml vs. 190 ml, P = 0.026) and lower incidence of serious complications (19.3% vs. 33.7%, P = 0.034), especially in infections and respiratory issues. Sarcopenia was identified in 38.6% of CPAS patients who received tailored support. Additionally, the median postoperative hospital stay was notably shorter in the CPAS group (10 days vs. 15 days, P < 0.001), with no in-hospital deaths. These results suggest that personalized preoperative care effectively mitigates operative stress and postoperative complications. CONCLUSION: Implementing CPAS significantly enhances surgical safety and reduces complication rates in elderly gastric cancer patients, emphasizing the critical role of personalized preoperative care in surgical oncology for this demographic.
