Biologic differences between peripheral and transition zone prostate cancer.
BACKGROUND Prostate cancer arises in the transition zone (TZ) in approximately 20-25% of cases. Modern biopsy and surveillance protocols, and advances in prostate cancer imaging, have renewed interest in TZ prostate cancers. We compared TZ and PZ prostate cancer to determine if cancer location is independently associated with better outcomes. METHODS We evaluated an expanded cohort of 1354 me...
متن کاملMolecular differences in transition zone and peripheral zone prostate tumors.
Prostate tumors arise primarily in the peripheral zone (PZ) of the prostate, but 20-30% arise in the transition zone (TZ). Zone of origin may have prognostic value or reflect distinct molecular subtypes; however, it can be difficult to determine in practice. Using whole-genome gene expression, we built a signature of zone using normal tissue from five individuals and found that it successfully ...

متن کاملPI3K and mTOR inhibitor, NVP-BEZ235, is more toxic than X-rays in prostate cancer cells
Background: Radiotherapy and adjuvant androgen deprivation therapy have historically been the first treatment choices for prostate cancer but treatment resistance often limits the capacity to effectively manage the disease. Therefore, alternative therapeutic approaches are needed. Here, the efficacies of radiotherapy and targeting the pro-survival cell signaling components epidermal growth fact...
متن کاملp63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers
Objective(s): Prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. Differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. Considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...
