PURPOSE: We explored the clinical usefulness of serum carbonic anhydrase 9 as a potential biomarker for conventional renal cell cancer. MATERIALS AND METHODS: This study included 91 patients with conventional renal cell cancer and 32 healthy individuals. Enzyme linked immunosorbent assay was used to measure the carbonic anhydrase 9 level. A followup (median 38 months) was performed to track early recurrence after surgery for patients with localized disease. Recurrence-free survival curves were calculated by the Kaplan-Meier method and compared using the log rank test. RESULTS: The mean serum carbonic anhydrase 9 level in patients with metastatic conventional renal cell cancer (216.68 +/- 67.02 pg/ml) or localized conventional renal cell cancer (91.65 +/- 13.29 pg/ml) was significantly higher than in healthy individuals (14.59 +/- 6.22 pg/ml, p
