Abstract

OBJECTIVE: To investigate the prognostic significance of common preoperative laboratory variables evaluated before surgery for clear cell renal cell carcinoma (RCC). PATIENTS AND METHODS: We retrospectively analysed the records of 355 patients who had surgery for clear cell RCC, assessing: clinical factors, including preoperative laboratory measurements, i.e. haemoglobin level, leukocyte count, platelet count, erythrocyte sedimentation rate (ESR), serum calcium, alkaline phosphatase (ALP), albumin, bilirubin, alanine aminotransferase, aspartate aminotransferase, and red blood cells in urine; and pathological factors, with the survival rates after surgery. RESULTS: The presence of metastasis, tumour stage and tumour size, with the ESR and ALP before surgery, were identified as significant prognostic factors for progression-free survival in a multivariate analysis. The same factors were significant independent factors for disease-specific survival, except for ESR and ALP, which were nearly statistically significant. When limited to non-metastatic tumours only, the multivariate analysis showed that ESR and ALP, with tumour stage, grade, size and necrosis, were independent prognostic factors for disease-specific survival. CONCLUSIONS: Along with traditionally accepted prognostic factors, these results suggest that common laboratory variables assessed before surgery, e.g. ESR and ALP, might also be useful in assessing the prognosis for patients with non-metastatic clear cell RCC. Including various laboratory variables in prognostic algorithms for RCC should be considered after further validation in RCCs of various histological subtypes and stages.
