Abstract
Purpose
This study was performed to investigate the significance of preoperative erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) and postoperative ESR and CRP nadir as predictive factors for prognosis in patients with non-metastatic renal cell carcinoma (RCC).
Materials and Methods
In 66 patients with non-metastatic RCC for whom ESR and CRP could be measured before radical nephrectomy and during follow-up, the preoperative ESR, preoperative CRP, postoperative ESR nadir and postoperative CRP nadir were compared with the clinicopathological variables.
Results
Patients with elevated preoperative ESR or CRP levels were more likely to have tumors with adverse features, including larger tumor size, higher T stage, higher nuclear grade and more frequent metastasis at follow-up, as compared to those patients with lower preoperative ESR or CRP levels, respectively. Patients with an elevated postoperative CRP nadir developed metastasis more frequently at follow-up as compared to those patients with a lower level of postoperative CRP nadir. The univariate analyses identified tumor size, T stage, preoperative ESR, preoperative CRP and postoperative CRP nadir as significant prognostic factors for recurrence-free survival.
