Abstract

Purpose: The C-reactive protein-albumin-lymphocyte (CALLY) index, which simultaneously evaluates the nutritional, immunological, and inflammatory statuses, is a new prognostic biomarker in patients with various cancers; however, no study has reported the clinical significance of the CALLY index in patients with pancreatic cancer. This study aimed to investigate whether the preoperative CALLY index is a prognostic biomarker in patients undergoing surgical resection of pancreatic cancer.

Methods: We retrospectively enrolled 461 patients with pancreatic cancer who underwent surgical resection between January 2013 and December 2022. The overall survival (OS) and relapse-free survival (RFS) rates were calculated using the Kaplan-Meier method. Univariate and multivariate analyses were performed using Cox proportional hazards regression models.

Results: The optimal cut-off value for the preoperative CALLY index was 1.9. In the low CALLY group, patients were older (p = 0.012), more patients underwent pancreaticoduodenectomy (p = 0.002), the median tumor size was larger (p < 0.001), more patients had pathologically confirmed metastatic lymph nodes (p = 0.015) and worse pathological stage (p = 0.015), and fewer patients received adjuvant chemotherapy (p = 0.003). A low CALLY index was associated with decreased OS (22.1 vs. 37.9 months) and RFS (12.4 vs. 16.4 months). Univariate and multivariate analyses showed that the preoperative CALLY index was an independent prognostic factor for OS (p < 0.001) and RFS (p = 0.045).

Conclusion: The preoperative CALLY index is a prognostic biomarker for both OS and RFS in patients undergoing surgery for pancreatic cancer.
