Project description:THE PAN PROSTATE CANCER PROJECT: Many groups around the world have generated Whole Genome DNA Sequence (WGS) data from prostate cancer patients. The pan prostate group have gathered with the idea that the accumulated data, should be collected and compared in a common format including common storage, re-analysis through a single pipeline, and investigation to achieve a variety of scientific goals. The combined collection would include the following categories: (i) cancers from different ethnic groups: eg Caucasian, Asian, Black Caribbean; (ii) cancer from different stages of progression from normal, to organ-confined disease, to metastases; (iii) early-onset prostate cancer; (iv) prostate cancer from aggressive and indolent disease; and (v) prostate cancer patients managed by different treatments with information linked to long-term clinical follow up data in many cases.This study contains the initial pilot samples (train 1) from the CRUK-ICGC prostate group.
Project description:The reason why prostate cancer is significantly more common in Western than Asian men is unknown. Using a genome-wide approach to compare the genomic changes in prostate cancer tissues, we determined that those from Chinese patients lack key somatic genomic changes commonly found in Western patients, including the 21q22.2-22.3 deletion which causes the TMPRSS2:ERG fusion gene, and 10q deletion which leads to PTEN inactivation. The results were confirmed and their consequence on ERG expression was identified by study of a large series of Chinese and UK samples using tissue-microarrays. Subsequently, we identified significant AR genotype differences between UK and Chinese prostate cancer patients. The identification of specific somatic genomic differences in cancers from distinct populations may provide an opportunity to identify cancer-causing or protective factors.
