Abstract

We recently found that TMPRSS2:ERG fusion genes and PTEN loss, which are common in Western prostate cancers are infrequent in Chinese cases. As previous studies indicated a higher frequency of RAS and BRAF mutation rates in Eastern Asian than in Western prostate cancers and fusion genes involving the RAF family genes BRAF and RAF1 were recently identified in prostate cancer in the American population, we investigated BRAF and RAF1 alterations in Chinese prostate cancer. Using fluorescence in situ hybridization, we found that BRAF was truncated in five of 200 informative Chinese cases (2.5%) and that RAF1 was truncated in three of 204 informative cases (1.5%) and genomic rearrangements of these genes were significantly correlated with high Gleason scores (>7; P
