Detaljeret beskrivelse
This prospective, observational, analytical cohort study will be conducted at the General Surgery Clinic of Kocaeli City Hospital. The study will include patients aged 60 years and older who have gastric cancer and are scheduled for elective radical gastrectomy. A total of 328 patients are planned to be enrolled.
Preoperative assessment will include multidimensional frailty-related parameters, including the modified Frailty Index-11 (mFI-11), Montreal Cognitive Assessment (MoCA), handgrip strength, Nutritional Risk Screening 2002 (NRS-2002), Prognostic Nutritional Index (PNI), and skeletal muscle characteristics assessed on computed tomography at the L3 level. Baseline neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) levels will also be recorded.
Intraoperative data will include surgical approach, operative duration, and intraoperative blood loss. Postoperatively, NLR and CRP will be assessed on postoperative days 1, 3, and 5. Delirium will be evaluated using the Confusion Assessment Method (CAM). Postoperative complications will be recorded according to the Clavien-Dindo classification, together with hospital length of stay and handgrip strength before discharge.
The primary purpose of the study is to evaluate the association between multidimensional frailty phenotypes and postoperative outcomes and biological recovery in older patients undergoing gastric cancer surgery. The study will also investigate whether the surgical approach is associated with differences in biological recovery among patients with different frailty profiles.
