  ABSTRACT: Objectives: We aimed to determine the frequency of PTEN (phosphatase with tensin homology deleted in chromosome 10) hypermethylation in renal cell carcinoma (RCC) and its impact on overall (OS) and disease-free survival (DFS). The association between PTEN hypermethylation and clinic and pathologic factors was also analyzed. Materials and Methods: The authors analyzed 137 patients who had undergone a radical or partial nephrectomy between 1997 and 2011. The methylation pattern was quantified individually at multiple CpG islands that are located on the exon 1 of PTEN gene by pyrosequencing. Results: Mean follow-up was 32.3 months. PTEN hypermethylation was detected with a low frequency (3.6%). There were no deaths or disease recurrence among patients with PTEN hypermethylation. Determining the association between PTEN hypermethylation and clinical and pathological factors was not possible due to the low frequency observed. Conclusion: The results show that the methylation of promoter CpG sites in PTEN is relatively infrequent in renal carcinogenesis and has no prognostic impact on survival.
