Web23 apr. 2016 · In small cell lung cancer (SCLC), hypermethylation of the tumour suppressor Ras association domain family 1A (RASSF1A) is frequent. It is associated with SV40 polyomaviral infection in other tumours. WebWe found RARβ2 hypermethylation in 97.5% of PCa, 94.7% of HGPIN, and 23.3% of BPH. Methylation levels were significantly higher in PCa compared with HGPIN and BPH (P < 0.00001). By establishing an empiric cutoff value, we were able to discriminate between neoplastic and non-neoplastic tissue, with 94.9% sensitivity and 100% specificity.
