Preoperative pan-immune-inflammation value and geriatric nutritional risk index predict outcomes of elderly patients with endometrial carcinoma after radical surgery
摘要
To evaluate the prognostic value of preoperative geriatric nutritional risk index (GNRI) and pan-immune-inflammation value (PIV), individually and in combination, for overall survival (OS), recurrence-free survival (RFS), and two-year recurrence rates in this specific population.
Materials and methodsGNRI and PIV were calculated from preoperative laboratory data. Optimal cutoffs were determined by ROC analysis for 3-year OS. The associations with clinicopathological features and survival outcomes (OS, RFS, 2-year recurrence) were assessed. Independent prognostic factors were identified using multivariate Cox regression. The prognostic performance of the combined GNRI - PIV model was evaluated using time-dependent ROC analysis.
ResultsLow GNRI (< 97.8) and high PIV (≥ 292.3) were significantly associated with advanced FIGO stage, higher tumor grade, lymph node metastasis, and increased two-year recurrence rates (all P < 0.05). Multivariate analysis confirmed both low GNRI (OS: 95% CI: 1.58–3.70, HR = 2.42, P < 0.001; RFS: 95% CI: 1.43–3.24, HR = 2.15,P < 0.001) and high PIV (OS: 95% CI: 1.43–3.32, HR = 2.18, P < 0.001; RFS: 95% CI: 1.30–2.90, HR = 1.94, P = 0.001) as independent predictors of poorer survival. The combination of GNRI and PIV demonstrated superior prognostic performance for 3-year OS (AUC = 0.81) and RFS (AUC = 0.78) compared to either marker alone. Patients with low GNRI/high PIV had the worst 2-year recurrence rate (65.8%), while those with high GNRI/low PIV and high GNRI/high PIV had significantly lower rates (9.6% and 3.1%, respectively) and superior OS and RFS compared to other groups (P < 0.001).
ConclusionsLow GNRI (< 97.8) and high PIV (≥ 292.3) were significantly associated with advanced FIGO stage, higher tumor grade, lymph node metastasis, and increased two-year recurrence rates. Preoperative GNRI and PIV are potent, cost-effective, and independent prognostic biomarkers in elderly EC patients undergoing radical surgery. Their combination provides superior risk stratification for OS, RFS, and early recurrence, potentially guiding personalized adjuvant treatment and follow-up strategies.
