Abstract

Background:Malnutrition is common after colorectal cancer surgery and may persist beyond hospital discharge. This study aimed to assess postoperative nutritional status in patients with colorectal cancer at short term follow-up after discharge.
Methods:In this study, adult patients with pathologically confirmed colorectal cancer who underwent tumor resection were assessed at 2 weeks and 1 month postoperatively in an outpatient surgical clinic in Mashhad, Iran. Nutritional status was evaluated using the Patient-Generated Subjective Global Assessment (PG-SGA). Dietary intake was assessed using 3-day24-hour dietary recalls. Anthropometry and body composition were recorded. Nutrition-impact symptoms were graded using CTCAE v5. Physical function was assessed.
Results: A total of 117 patients were included with mean age 57.55 ± 13.18 years and 55.6% were female. The mean PG-SGA score increased from 9.32±4.03 at 2 weeks to 10.41±3.50 at 1 month postoperatively(p
