This prospective observational study will evaluate the association between ERAS protocol compliance and postoperative nutritional outcomes in 120 patients undergoing lung cancer surgery. ERAS compliance will be recorded, and patients will be classified as having high, moderate, or low compliance. NRS-2002 and PNI will be assessed before surgery and at postoperative 48 hours. Hospital stay and postoperative complications will also be evaluated.
This single-center observational cohort study will include 120 patients aged 18-85 years undergoing elective lung cancer surgery. No intervention will be assigned. ERAS compliance will be categorized as high (≥80%), moderate (60-79%), or low (\<60%). Changes in NRS-2002 and PNI, hospital stay, and postoperative complications will be evaluated using routine clinical data.
Study Type
OBSERVATIONAL
Enrollment
120
Patients receive routine perioperative care according to the institutional ERAS protocol. No intervention is assigned by the investigators. ERAS compliance is assessed observationally.

Change in Nutritional Risk Screening 2002 Score
NRS-2002 will be assessed before surgery and at postoperative 48 hours. The score ranges from 0 to 7, with higher scores indicating greater nutritional risk. Change will be calculated as the postoperative score minus the preoperative score.
Time frame: From preoperative assessment to 48 hours after surgery
Change in Prognostic Nutritional Index
PNI will be calculated as (10 × serum albumin \[g/dL\]) + (0.005 × total lymphocyte count \[/mm³\]). Higher values indicate better nutritional status. Change will be calculated as the postoperative value minus the preoperative value.
Time frame: From preoperative assessment to 48 hours after surgery
Length of Hospital Stay
Number of days from the date of surgery to hospital discharge.
Time frame: From surgery to hospital discharge, assessed up to 30 days
Postoperative Complications
Occurrence of any postoperative complication documented during hospitalization or at the 30-day follow-up.
Time frame: From surgery to 30 days after surgery
ERAS Protocol Compliance
The number of applied ERAS components divided by the total number of applicable components and expressed as a percentage. Higher percentages indicate greater compliance.
Time frame: Perioperative/Periprocedural
