Abstract
This study aimed to compare the prognostic significance of inflammatory and nutritional parameters, calculated based on hemogram and biochemical values at the time of diagnosis, in patients diagnosed with renal cell carcinoma (RCC). A total of 120 patients diagnosed with RCC and receiving diagnosis and/or treatment at our center were included in the study. Among the inflammatory and nutritional parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and Memorial Sloan Kettering prognostic score (MPS) were calculated and analyzed. The most common pathological subtype was the clear cell variant (69.2%). 25.8% of the patients were at the metastatic stage. Univariate Cox regression analysis revealed that tumor size, tumor grade, sex, stage, presence of metastasis, number of metastases, IVC involvement, history of radiotherapy (RT), hemoglobin, NLR, PLR, PNI, albumin, C-reactive protein (CRP), MPS, and mGPS had a significant impact on survival. Furthermore, stage, number of metastases, and PNI were identified as independent prognostic factors for survival. When clinical parameters were excluded from the analysis, NLR, LDH, and mGPS emerged as independent prognostic factors for survival.As demonstrated by the results of the multivariate analysis, stage, number of metastases, and PNI were found to be more influential independent prognostic factors. This study suggests that nutritional parameters have greater prognostic value than inflammatory markers in RCC, and that a simple nutritional scoring system performed at the time of diagnosis may provide improved prognostic accuracy. Additionally, our findings indicate that the MPS, which was evaluated for the first time in RCC in this study, also has prognostic significance, and it may potentially become an independent prognostic marker in future studies with larger patient populations.
