Background Due to great differences in physiological reserve, psychological status and social functioning, frailty in elderly patients with gastric cancer may present various subtypes. The relationship between preoperative frailty and postoperative adverse outcomes in them still remains to be further explored. Objective To explore the relationship between preoperative frailty subtypes and postoperative adverse outcomes〔total complications, prolonged length of stay (PLOS), low quality of life (QOL), and disability〕among elderly patients with gastric cancer. Methods From March to October 2021, 404 elderly gastric cancer patients were selected from Department of Gastric Surgery, the First Affiliated Hospital with Nanjing Medical University by convenience sampling. The General Demographic Data Questionnaire and Tilburg Frailty Indicator were used to collect demographics and frailty status before surgery. Total complications and PLOS were collected from the electronic medical records, and the status of disability and QOL were obtained using a telephone follow-up at one month after discharge. Univariate Logistic regression was performed to explore the influencing factors of postoperative adverse outcomes. Multivariate Logistic regression analysis was performed to analyze the association of preoperative frailty subtypes with postoperative adverse outcomes, with potential confounders adjusted. Results Two hundred and eighty-five cases were found with preoperative frailty, and the frailty subtypes in them were classified into eight classes: exclusive physical frailty〔77 (19.1%) 〕, exclusive psychological frailty〔78 (19.3%) 〕, exclusive social frailty〔23 (5.7%) 〕, physical and psychological frailty〔63 (15.6%) 〕, physical and social frailty〔13 (3.2%) 〕, psychological and social frailty〔16 (4.0%) 〕, multidimensional frailty (physical, psychological, and social frailty) 〔15 (3.7%) 〕. The other 119 (29.5%) cases had no preoperative frailty. In the univariate Logistic regression, age was the factor influencing total complications〔OR=1.063, 95%CI (1.021, 1.106), P=0.003〕. History of pharmacological treatment〔OR=1.549, 95%CI (1.016, 2.362), P=0.042〕and surgical approach〔OR=2.103, 95%CI (1.191, 3.712), P=0.010〕were the factors influencing PLOS. Marital status〔OR=4.611, 95%CI (1.079, 19.706), P=0.039〕, living in an urban area〔OR=1.614, 95%CI (1.009, 2.582), P=0.046〕, having at least two comorbidities〔OR=1.694, 95%CI (1.038, 2.766), P=0.035〕were the factors influencing postoperative low QOL. Living in an urban area〔OR=0.601, 95%CI (0.390, 0.926), P=0.021〕, history of pharmacological treatment〔OR=1.663, 95%CI (1.082, 2.558), P=0.020〕, and advanced TNM stages〔OR=1.659, 95%CI (1.017, 2.706), P=0.043〕were the factors influencing postoperative disability. In the multivariate Logistic regression, the preoperative multidimensional frailty was independently associated with total complications, with age adjusted〔OR=5.344, 95%CI (1.715, 16.656), P=0.004〕. The preoperative physical frailty〔OR=2.048, 95%CI (1.078, 3.891), P=0.029〕, preoperative psychological frailty〔OR=2.077, 95%CI (1.103, 3.913), P=0.024〕and preoperative multidimensional frailty〔OR=8.321, 95%CI (2.400, 28.848), P |
