Pan-immune-inflammation value (PIV) is a systemic immune response marker that can predict the prognosis of patients with colon cancer. However, the specific distinction between PIV of LCC and RCC remains unclear.  \nAIM  \nTo investigate the prognostic and clinical significance of PIV in LCC and RCC patients.  \nMETHODS  \nThis multicenter retrospective cohort study included 1510 patients with colon cancer, comprising 801 with LCC and 709 with RCC. We used generalized lifting regression analysis to evaluate the relative impact of PIV on disease-free survival (DFS) in these patients. Kaplan-Meier analysis, as well as univariate and multivariate analyses, were used to examine the risk factors for DFS. The correlation between PIV and the clinical characteristics was statistically analyzed in these patients.  \nRESULTS  \nA total of 1510 patients {872 female patients (58%); median age 63 years [inter-  \n WJG  [https://www.wjgnet.com](https://www.wjgnet.com) 3823 September 7, 2024  Volume 30  Issue 33   \nWang QY et al. PIV between in LCC and RCC  \nquartile ranges (IQR): 54-71]; patients with LCC 801 (53%); median follow-up 44.17 months (IQR 29.67-62.32)} were identified. PIV was significantly higher in patients with RCC [median (IQR): 214.34 (121.78-386.72) vs 175.87 (111.92-286.84), P \u003C 0.001] . After propensity score matching, no difference in PIV was observed between patients with LCC and RCC [median (IQR): 182.42 (111.88-297.65) vs 189.45 (109.44-316.02); P = 0.987] . PIV thresholds for DFS were 227.84 in LCC and 145.99 in RCC. High PIV (> 227.84) was associated with worse DFS in LCC [PIV-high: Adjusted hazard ratio (aHR) = 2.39; 95% confidence interval: 1.70-3.38; P \u003C 0.001] but not in RCC (PIV-high: aHR = 0.72; 95% confidence interval: 0.48-1.08; P = 0.114) .  \nCONCLUSION  \nThese findings suggest that PIV may predict recurrence in patients with LCC but not RCC, underscoring the importance of tumor locat","cbCaivDoY1wOFgTo","https://ap.wps.com/l/cbCaivDoY1wOFgTo","pdf",4722314,15,"English","# Abstract\n## Background\n## Aim\n## Methods\n## Results\n## Conclusion\n# Introduction\n## Role of inflammation and PIV in colorectal cancer","[{\"question\":\"What is pan-immune-inflammation value (PIV) and why is it studied in colon cancer?\",\"answer\":\"PIV is a systemic immune response marker.
