Predicting Overall Survival Using Preoperative Nutritional and Inflammation Status for Colorectal Cancer.

AIM

It has been shown that nutritional status and inflammation correlate with survival in patients with various cancer types. In this study, we evaluated several kinds of nutritional and inflammation parameters in preoperative blood samples and constructed new risk model predicting survival in patients with colorectal cancer.

PATIENTS AND METHODS

We retrospectively examined 286 patients with stage I-III colorectal cancer who had undergone curative resection at Teikyo University Hospital. The association between overall survival (OS) and nutritional status and inflammation factors were examined using Kaplan-Meier curves and log-rank tests.

RESULTS

Serum albumin, cholesterol and C-reactive protein concentration, neutrophil count and platelet count were shown to be correlated with OS. We constructed a new risk model (nutrition inflammation status, NIS) using these factors, and compared it with other nutrition and inflammation models.

CONCLUSION

NIS was useful as a new model for predicting OS in patients undergoing curative resection for colorectal cancer, compared with known models.
