In the literature, the relationship between frailty and various blood tests such as beta-2 microglobulin, CRP, procalcitonin, vitamin D, IL-1, and IL-6 has been investigated (2). In our study, the investigators aim to investigate the relationship between frailty status assessed using frailty scale forms (Frailty Scale Version 9, Quality of Life Scale Short Form-36) and preoperative levels of Albumin/Creatinine, B12, Folate, Ferritin, hemogram, Sedimentation Rate, and CRP in patients undergoing gastrointestinal malignancy surgery. By identifying the relationship among these parameters, the investigators believe that modifiable factors contributing to frailty in patients at risk can be addressed through appropriate interventions.

Frailty is a condition associated with a decline in physiological performance. Patients are categorized as healthy, pre-frail, or frail based on physiological and functional characteristics. Frailty is known to be influenced by various lifestyle factors such as socioeconomic status, psychological factors, diet, exercise, and genetic predisposition. With aging, there is an increase in cognitive and physical dysfunction, which correlates with an increase in frailty. Along with frailty, geriatric symptoms, mortality, and other negative health outcomes also increase in the elderly population. Therefore, early detection of frailty is crucial to implementing lifestyle changes aimed at improving cognitive and physical status. Various assessment scales are used to evaluate frailty, such as the Frailty Scale Version 9, Quality of Life Scale Short Form-36, and Modified 5-item frailty index (mFI-5) In the literature, the relationship between frailty and various blood tests such as beta-2 microglobulin, CRP, procalcitonin, vitamin D, IL-1, and IL-6 has been investigated (2). In our study, the investigators aim to investigate the relationship between frailty status assessed using frailty scale forms (Frailty Scale Version 9, Quality of Life Scale Short Form-36) and preoperative levels of Albumin/Creatinine, B12, Folate, Ferritin,hemogram, Sedimentation Rate, and CRP in patients undergoing gastrointestinal malignancy surgery.
