Objective By mining data from the Database of Colorectal Cancer (DACCA) at West China Hospital of Sichuan University, this study aims to evaluate the relationship between nutritional risk screening (NRS) 2002 scores at initial diagnosis and long-term survival in patients. Methods The DACCA database version from November 24, 2023, was selected to compare the clinicopathological data of patients with NRS2002 scores <3 and ≥3, and to explore the impact of NRS2002 scores on survival. Results A total of 723 patients were screened, with 585 (80.9%) had NRS2002 scores <3 and 138 (19.1%) had NRS2002 scores ≥3. All 723 patients were followed up, with a follow-up period ranging from 1 to 78 months and a median follow-up time of 34 months. The median survival time for patients with NRS2002 scores <3 was 35 months, while it was 31 months for those with NRS scores ≥3. During the follow-up period, 589 patients (81.5%) survived, including 515 (71.2%) tumor-free survivors and 74 (10.2%) survivors with tumors. There were 134 deaths (18.5%), including 126 cancer-related deaths (17.4%) and 8 non-cancer-related deaths (1.1%). Multivariate logistic regression results showed that after controlling for 6 factors including age, radical surgery, adjuvant therapy, hypertension, differentation, and TNM staging, NRS2002 score was not a factor affecting the survival of colorectal cancer patients (RR=0.98, P=0.875). Conclusion NRS2002 score is not a predictive factor for the survival of colorectal cancer patients, possibly because although patients may have nutritional risks preoperatively, the long-term impact on survival is minimal following surgery and postoperative recovery.
