This prospective, single-center observational cohort study will include patients aged 60 years or older who are scheduled to undergo elective surgery for gastrointestinal cancer at Van Training and Research Hospital.\n\nBefore surgery, demographic and clinical characteristics, including age, sex, and cancer diagnosis, will be recorded. Sarcopenia will be evaluated according to the EWGSOP2 criteria using measurements of muscle strength, muscle mass, and physical performance. The SARC-F questionnaire and calf circumference measurement will also be performed as part of the preoperative assessment.\n\nParticipants will receive standard surgical and perioperative care, and no treatment or intervention will be assigned by the study protocol. Patients will be observed for 90 days after surgery. Outcomes will include postoperative surgical complications, length of hospital stay, 30-day mortality, and 90-day mortality. Postoperative complications of interest will include anastomotic leakage, wound-related complications, oral intake intolerance, and delayed mobilization. The study will compare these outcomes between patients with and without preoperative sarcopenia and assess whether sarcopenia is independently associated with adverse postoperative outcomes.","Patients aged 60 years or older with gastrointestinal system cancer who are scheduled to undergo elective surgery at the General Surgery Clinic of Van Training and Research Hospital.",[33,38],{"label":34,"type":26,"description":35,"interventionNames":36},"Participants With Preoperative Sarcopenia","Participants aged 60 years or older undergoing elective surgery for gastrointestinal cancer who are identified as having preoperative sarcopenia according to the EWGSOP2 criteria.
