Researchers from The Institute of Cancer Research and The Royal Marsden NHS Foundation Trust in London gave 258 men with the otherwise untreatable cancer the immunotherapy agent Keytruda (pembrolizumab).
The world's leading expert on prostate cancer Professor Johann de Bono from the Institute of cancer research said: "We hope for a revolutionary cure, but they can't call it".More news: Argentina friendly set to be cancelled after Messi threats
Scores of men with the most lethal form of prostate cancer have been "brought back from the brink of death" by a drug found to work where all others have failed in a groundbreaking British-led trial.
It is the first time immunotherapy has been shown to benefit some men with prostate cancer, the researchers said.
Nonetheless, for sufferers reminiscent of these within the new examine with docetaxel-refractory metastatic castration-resistant prostate most cancers, there may be at present no efficient therapy. Black patients experienced higher rates of several hormonal-based toxicities, such as hyperglycemia, hypokalemia, and hot flashes, "suggesting perhaps a greater exposure risk to this medicine", George said. Prostate cancer can develop when cells in the prostate start to grow in an uncontrolled way. The immunotherapy is used for the treatment of cancers of the advanced stage including the cancers of lung and melanoma. It is an IgG4 isotype antibody that blocks a protective mechanism of cancer cells, and allows the immune system to destroy those cancer cells.More news: Arsenal turn down Marouane Fellaini free transfer opportunity
Unfortunately, only 10 - 15% of the patients responded to immunotherapy, making the approach ineffective for the majority of prostate cancer patients. Importantly, the medications only work for some patients.
Professor Bono concludes, "This new trial has found that testing for mutations in DNA fix genes could be a valuable marker of who will respond".
"The challenges we now face are how to predict in advance who will benefit, and how to make immunotherapy work for more people". With regard to patients' definitive prostate cancer treatment, 186 (94%) patients had undergone radical prostatectomy (RP) and the remaining 11 (6%) received external beam radiation therapy (EBRT). Prostate cancer is treated in a number of ways, but the more extreme treatments which include surgical interventions may cause physical and psychological side effects.More news: IOS 12 features we missed: second Face ID user and many more
