In a population-based study reported in The Lancet Oncology, Downing et al found little difference in health-related quality of life (HRQOL) between men with advanced vs localized prostate cancer. Sexual function problems were common among all patients—and often not addressed—and use of ...
In a letter to the editor of The New England Journal of Medicine, Goodman et al reported a long-term follow-up of the Prostate Cancer Prevention Trial indicating that finasteride treatment was not associated with an increased risk of death from prostate cancer. Study Details As previously...
Unlike healthy tissues, tumors thrive in low-oxygen environments, often acquiring the ability to resist treatment and spread to other sites in the body. Despite being a well-known cause of therapy resistance and metastasis, the impact of hypoxia on tumor cells is poorly understood. Researchers have ...
A subset of patients with aggressive prostate cancer are carriers of germline BRCA2 mutations, which are also linked to hereditary breast cancer, ovarian cancer, and pancreatic cancer. Study findings also showed family members of patients with prostate cancer who carry BRCA2 and DNA-repair...

Black men diagnosed with prostate cancer classified as low risk may actually have a more aggressive form of the disease that is more likely to be fatal than in nonblack men placed in the same prognostic category, according to results from a new study published as a research letter by Mahal et al in ...
As reported in the Journal of Clinical Oncology by Dignam et al, analysis of outcomes in the phase III NRG/RTOG 9202 trial indicates that the time interval to biochemical failure (IBF) could serve as a surrogate endpoint for clinical outcomes in patients receiving radiotherapy plus long-term...
As reported by Denham et al in The Lancet Oncology, 10-year results of the phase III TROG 03.04 RADAR trial have shown that 18 months of androgen suppression plus radiotherapy is more effective than 6 months of androgen suppression plus radiotherapy in locally advanced prostate cancer, but no...
Although most major cancer organizations agree on the guidelines for prostate cancer screening, there is still uneven application of the test, such as in the older patient population, resulting in overdiagnosis and waste in an already fiscally challenged health-care system. Researchers from the...
ONE OF the pressing issues in metastatic castration-resistant prostate cancer is the development of resistance to therapies directed at the androgen receptor (AR), such as enzalutamide (Xtandi) and abiraterone acetate (Zytiga). Research is ongoing to identify mechanisms of resistance in the hope of ...
FORMAL DISCUSSANT Joaquin Mateo, MD, PhD, of the Prostate Cancer Translational Research Group, Vall d’Hebron Institute of Oncology, Barcelona, said that the TRITON2 findings were encouraging, although still preliminary. “We should interpret these results with caution, because this interim analysis ...
THE SEARCH for biomarkers in prostate cancer has proved frustrating, partly due to the complexity of the disease and its heterogeneity. A preliminary analysis of a phase II (TRITON2) study suggests that rucaparib (Rubraca), a poly (ADP-ribose) polymerase (PARP) inhibitor, may be active in men with...
In a cohort study reported in JAMA Oncology, Tilki et al found that patients with Gleason score 9–10 prostate cancer treated with multimodality therapy known as MaxRP (radical prostatectomy [RP] plus adjuvant external-beam radiotherapy [EBRT] with or without androgen-deprivation therapy...
