High preoperative modified frailty index has a negative impact on short- and long-term outcomes of octogenarians with gastric cancer after laparoscopic gastrectomy
The proportion of elderly patients who undergo surgery has rapidly increased. However, clinical indicators that predict outcomes are limited. Frailty is thought to estimate physiological reserves, although its use has not been evaluated in laparoscopic surgical patients. This study aimed to evaluate the significance of preoperative modified frailty index (PMFI) in octogenarians undergoing a laparoscopic gastrectomy.
We reviewed prospectively collected data from 119 patients with gastric cancer (GC) aged 80 years or older who underwent a radical laparoscopic gastrectomy (RLG) between January 2007 and December 2012. Three baseline frailty traits were measured using routine preoperative laboratory data: albumin < 3.4 g/dL, haematocrit < 35%, and creatinine > 2 mg/dL. Patients were categorized by the number of positive traits as follows: low preoperative modified frailty index (LPMFI): 0–2 traits and high preoperative modified frailty index (HPMFI): 3 traits. We compared patient characteristics, operative outcomes, pathological results, morbidity, and survival.
A total of 43 (36.1%) patients were considered HPMFI, and 76 (63.9%) patients were considered LPMFI. HPMFI was associated with an increased risk of postoperative complications (HPMFI group: odds ratio 2.506; 95% CI, 1.113–5.643, P = 0.027). With a median follow-up of 39.0 months, the 3-year overall survival (OS), recurrence-free survival (RFS), and cancer-specific survival (CSS) rates for the entire cohort were 47.9, 34.3, and 51.7%, respectively. Significant differences were observed in OS (HPMFI group, 37.2%; LPMFI group, 53.9%; P = 0.038) and RFS (HPMFI group, 23.3%; LPMFI group, 40.5%; P = 0.012) between the groups, but no difference was found for CSS (HPMFI group, 43.5%; LPMFI group, 56.4%; P = 0.078).
HPMFI based on an easily calculable preoperative measure may be useful for predicting postoperative complications and have a negative impact on 3-year OS and RFS after an RLG in octogenarians. Therefore, HPMFI can serve as a low-cost, simple screen for high-risk individuals who might suffer more than expected during the postoperative period after an RLG.
