Background: Rather body mass index (BMI) has a potential prognostic role in determining the outcome of patients suffering from colorectal cancer or not should be clear. Objectives: We aimed at effects BMI on prognosis with cancer. Methods: In this cohort study, documents 1550 between 2002 and 2020 Omid hospital Emam Reza (Mashhad, Iran) databases were evaluated, retrospectively. The multivariable logistic regression Cox proportional hazard regressions used significance level P < 0.05. Results: Nine hundred twenty included current study. Most categorized as normal weight (38.91%). prevalence underweight overweight/obese 26.19% 34.9%, respectively. There was no significant difference overall survival (OS) disease-free (DFS) based (OS: 108.2 ± 7.0 months for underweight, 124.0 6.2 weight, 130.9 4.5 patients; = 0.2 DFS: 97.0 6.5, 110.0 5.6, 113.7 5.0, respectively; 0.3). Conclusions: had effect long-term outcomes However, there an insignificant trend to better higher comparing group.
