Patient background and perioperative outcomes were evaluated in two groups: low G8 (&lt;14) and high G8 (\u226514). The effects of age and body mass index (BMI) were assessed using logistic regression models adjusted for inverse\u2010probability treatment weighting in the low G8 and high G8, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 37 cases were categorized as low G8 and 30 cases as high G8. Significant differences in patient background were found in terms of age, BMI, American Society of Anesthesiologists physical status, presence of dementia, and estimated glomerular filtration rate (eGFR). Significant differences in perioperative outcomes were observed in the operative time and number of lymph node dissections. Postoperative delirium and eGFR were significantly higher in the low G8 group. The high G8 group showed significantly higher recurrence\u2010free survival and overall survival rates than the low G8 group. After adjustment using the inverse\u2010probability treatment weighting method, postoperative delirium and eGFR were significantly higher in the low G8 group but there were no significant differences in recurrence\u2010free survival rates, cancer\u2010specific survival, or overall survival.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>After adjusting for age and BMI,
