New Way to Fight Therapy-Resistant Prostate Cancer Found

Scientists have identified a signalling circuit in cells that can be targeted to treat advanced prostate cancer in patients who are resistant to existing therapies. Prostate cancer is the second-leading cause of death after lung cancer in American men, researchers said. Currently, the most effective treatment for advanced prostate cancer is to deprive the cancer of what feeds it – androgen hormones, such as testosterone. However, almost all patients eventually develop resistance to this therapy, leaving doctors with no options to counteract the inevitable. The study at The Scripps Research…

Laser therapy with deep-sea drug kills prostate cancer cells

A non-surgical treatment for lowrisk prostate cancer, in which doctors inject a light-sensitive drug derived from deep-sea bacteria into a patient’s bloodstream, was shown in a trial to kill cancer cells without destroying healthy tissue. Results of a trial in 413 patients showed that the drug, which is activated with a laser to destroy tumour tissue in the prostate, was so effective that half the patients went into remission, compared with 13.5% in a control group.”These results are excellent news for men with early localised prostate cancer, offering a treatment…

Prostate cancer spread can be predicted through tumour cells in blood samples

Prostate cancer spread can be predicted through tumour cells in blood samples (Shutterstock Images) A new study says that researchers have found a group of circulating tumour cells in prostate cancer patient blood samples which are linked to the spread of the disease. This is the first time these cell types have been shown to be a promising marker for prostate cancer spread. In a study, presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool, of around 80 samples from men with prostate cancer, scientists at the…

Prostate cancer treatment may trigger dementia in men

A common hormone therapy to treat prostate cancer may double a man’s risk of dementia, regardless of his age, found a recent study conducted by Penn Medicine researchers. Last year, the researchers discovered a dramatic association between Alzheimer’s disease and androgen deprivation therapy (ADT), a mainstay of treatment for prostate cancer since the 1940s currently used in over a half million men in the United States. This new study suggests a broader neurocognitive risk associated with the testosterone-lowering therapy. While the findings do not prove that ADT increases the risk…

Family History Important Factor for Prostate Cancer: Study

PhotoCredit:istock Research in Sweden published on Monday found family history an important factor in men developing various types of prostate cancer. “Men with brothers who have had prostate cancer run twice as high a risk of being diagnosed themselves in comparison to the general population,” the study by Umea University and Lund University said. “It’s well known that men with prostate cancer in the family have a higher risk of the disease,” said Par Stattin, researcher at the Department of Surgical and Perioperative Sciences and principal investigator of Prostate Cancer…
