Abstract
Background/Aim: The CRP-albumin-lymphocyte (CALLY) index is a promising biomarker. We clarified the clinical impact of the CALLY index in gastric cancer patients who received curative treatment. Patients and Methods: Consecutive patients who underwent curative resection for gastric cancer at Yokohama City University from 2005 to 2020 were selected based on medical records. The CALYY index was calculated as follows: serum ALB level (g/dl) × lymphocyte count (cells/μl)/C-reactive protein (mg/dl) ×10<sup>4</sup>. Results: Two hundred fifty-nine patients were included in the present study. The three- and five-year overall survival (OS) rates were 64.8% and 57.0%, respectively, in the CALLY index-low group, and 86.2% and 78.2%, respectively, in the CALLY index-high group. There were significant differences between the two groups. A multivariate analysis demonstrated that the CALLY index was an independent prognostic factor for overall survival (hazard ratio=1.791; 95% confidence interval=1.067-3.009; p=0.028). When comparing the perioperative clinical course between the CALLY index-low and CALLY index-high groups, there were significant differences in postoperative surgical complications and adjuvant chemotherapy. Conclusion: The CALLY score was an independent prognostic factor for patients with gastric cancer. Our results suggest that the CALLY index is a promising tool for assessing inflammation and nutritional status in patients undergoing gastric cancer treatment and management.
