OBJECTIVES: Adipose tissue distribution and radiodensity are associated with prognosis in many types of cancer. However, the roles of adipose tissue distribution and radiodensity in patients with metastatic colorectal cancer (mCRC) remain unclear. The aim of this study was to assess the prognostic effect of adiposity and adipose tissue radiodensities in patients with mCRC.
METHODS: Patients with mCRC who received first-line palliative chemotherapy and had a computed tomography (CT) scan at the third lumbar vertebra (L3) level, admitted between January 2010 and December 2018, were sequentially enrolled. Body composition was assessed using CT-derived measurements. Univariate and multivariate logistic regression analyses and Kaplan-Meier curves were used to determine prognostic values.
RESULTS: The study included 237 patients. Cox analyses demonstrated that high subcutaneous adipose tissue (SAT) index was associated with a lower risk for death (hazard ratio [HR], 0.51; 95% confidence interval [CI], 0.29-0.88; Ptrend < 0.025). There was no significant association between visceral adipose tissue (VAT) index tertiles and overall survival. However, high VAT and SAT radiodensities were significantly associated with increased mortality (HR, 1.80; 95% CI, 1.12-2.89; Ptrend < 0.030 and HR, 1.85; 95% CI, 1.19-2.86; Ptrend < 0.021, respectively).
CONCLUSIONS: A higher SAT index in patients with mCRC was associated with a favorable overall survival outcome, whereas higher SAT and VAT radiodensities were associated with an increased risk for death, supporting that early nutritional intervention may improve mCRC prognosis.
