Abstract:
Purpose:To assess the prognostic value of the preoperative neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic immune-inflammation response index (SIRI) in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU).
Materials and Methods:One hundred seven patients were retrospectively enrolled. Chi-square (χ 2 ) tests were adopted to assess the association of the inflammatory ratios and indexes to clinical risk factors. Overall survival (OS), metastasis-free survival (MFS), local, lymph node, and contralateral recurrence-free survival (RFS) were estimated by the Kaplan–Meier method and the corresponding curves were compared using log-rank test. Univariate and multivariate survival analysis were performed using general linear models to identify risk factors for prognosis.
Results:NLR, MLR, PLR, SII, and SIRI were predictive of OS (p=0.024, p=0.025, p=0.004, p=0.006, and p=0.03, respectively). Besides, PLR was predictive of local (p<0.001) and lymph node RFS (p=0.014) and SII was associated to lymph node and contralateral RFS prediction (p=0.034 and p=0.023, respectively). All candidate markers adding high NLR+high MLR+high PLR combination were independent risk factors of OS. PLR was an independent risk factor of local and lymph node RFS whereas the above cited combination and NLR were independent prognosticators of local and contralateral RFS respectively. All markers were correlated to poor postoperative clinical characteristics mainly pathological grade (p<0.05).
Conclusions:Preoperative NLR, MLR, PLR, SII, and SIRI were associated with higher pathologic features and worse oncological outcomes in patients treated with RNU for UTUC.
