8p22-p23 LOH

Tuesday 18 September 2007


- prostatic adenocarcinoma (16470536)

  • Allelic loss at 8p22-p23 was significantly more frequent in clinical prostate cancer (CPC) than in incidental prostate cancer and in pT4 CPC than in earlier-stage CPC. (16470536)
  • Deletion of 8p is an important event in both the initiation and metastasis of prostate cancer.
  • The extremely high frequency of LOH at 8p22-23.1 in high-grade tumors suggests the existence of a novel putative tumor-suppressor gene associated with the progression of prostate cancer.
