Abstract

Background

The aim of this study was to elucidate the clinical impact of the CALLY index in patients with gastric cancer (GC) undergoing gastrectomy.

Methods

Between January 2014 and December 2020, 617 patients who underwent gastrectomy for GC at the Osaka City General Hospital were enrolled in this study. The CALLY index was calculated using the following formula: [albumin (g/dL) × lymphocytes (/μl)]/[CRP (mg/dL) × 104]. We compared the predictive value of four biomarkers [CALLY index, modified Glasgow prognostic score (mGPS), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR)] for short- and long-term outcomes and focused on the CALLY index to elucidate its clinical value.

Results

Receiver operating characteristic analysis showed that the area under the curve for the CALLY index was the highest among the four biomarkers. The 5-year overall survival (OS) and cancer-specific survival (CSS) rates in the low and the high CALLY groups were statistically significant. Multivariate analysis identified the CALLY index as an independent factor for OS and CSS but not NLR or PLR. The mGPS was an independent factor for OS but not for CSS in multivariate analysis. Regarding complications, only the CALLY index was an independent predictor of major complications (≧ Clavien–Dindo grade 3) in multivariate analysis but not others.

Conclusions

The CALLY index may have a clinical value in predicting OS, CSS, and major complications in GC patients undergoing gastrectomy.
