Erythrocyte sedimentation rate as a prognostic factor in renal cell carcinoma

In a follow-up study of 193 adult patients with renal cell carcinoma diagnosed in northern Norway 1974-1980, ESR as a prognostic factor was studied with the Cox regression model. In 71 patients (37%) metastatic disease was known at diagnosis. In patients without metastatic disease an elevated ESR greater than 15 mm/h and renal vein involvement were significant prognostic factors indicating short survival. Multivariate survival analyses of all patients showed the presence of metastatic disease and elevated ESR (greater than 15 and greater than 30 mm/h) as significant prognostic factors indicating high-risk patients. This study concludes that ESR deserves attention as a prognostic discriminator in renal cell carcinoma.
