“Salvage prostate cryoablation may be an effective treatment that can help delay the need for androgen deprivation therapy (ADT) in carefully selected men with locally recurrent prostate cancer, according to a new study presented at the American Urological Association 2018 annual meeting.
“Researchers at Fox Chase Cancer Center studied the outcomes of 52 men with nonmetastatic prostate cancer who were initially treated with radiation therapy but later suffered recurrence and received salvage cryoablation. The investigators identified the men from a prospective database of patients undergoing salvage cryoablation after definitive prostate radiation by external beam radiation therapy, brachytherapy, or both. While ADT is the common second-line therapy, these men instead received cryoablation.”
“Men on hormone therapy for prostate cancer may benefit significantly from hitting the gym with fellow patients and choosing more veggies and fewer cheeseburgers, a new study suggests.
“Androgen deprivation therapy is a powerful tool against prostate cancer, and more and more men are opting for the treatment as a growing array of hormone-based therapies become available.
“But it comes with a cost. Suppressing male hormones, including testosterone, that fuel cancer growth also means that patients lose strength and muscle mass and gain fat. And that puts the men at risk for other health problems, including heart disease and diabetes.”
“Use of Xtandi in early stage prostate cancer on top of standard hormone therapy reduced the risk of disease spreading or death by 71 percent compared with hormone therapy alone, study results that could lead to significantly increased sales of the Pfizer Inc and Astellas Pharma Inc medicine.
“The data from a highly anticipated study released on Monday showed that it took 36.6 months for the disease to spread to other parts of the body in patients who received Xtandi plus androgen deprivation therapy (ADT), a measure known as median metastasis-free survival. That compared with 14.7 months for ADT alone, a highly statistically significant difference of nearly two years.”
“Adding docetaxel to androgen-deprivation therapy (ADT) improved overall survival (OS) by nearly 17 months in men with high-volume metastatic hormone-sensitive prostate cancer. Investigators for the multicenter phase III CHAARTED trial noted that the survival benefit did not extend to men with low-volume disease.
“In this updated analysis, the median OS was 57.6 months for the chemohormonal therapy arm versus 47.2 months for ADT alone (hazard ratio [HR], 0.72; 95% CI, 0.59-0.89; P = .0018) at a median follow-up of 53.7 months. For patients with high-volume disease (n = 513), the median OS was 51.2 months with chemohormonal therapy versus 34.4 months with ADT alone (HR, 0.63; 95% CI, 0.50-0.79; P <.001).”
“European regulators are allowing earlier use of Janssen’s Zytiga in the treatment pathway for metastatic prostate cancer.
“Zytiga (abiraterone) plus prednisone/prednisolone has been approved to treat newly-diagnosed high-risk metastatic hormone-sensitive prostate cancer (mHSPC) in adult men in combination with androgen deprivation therapy (ADT).
“The drug is already available in Europe for metastatic castration-resistant prostate cancer (mCRPC) in adults who are asymptomatic or mildly symptomatic after failure of ADT in whom chemotherapy is not yet clinically indicated and in adult men whose disease has progressed on or after a docetaxel-based chemotherapy regimen.”
“Back-to-back discoveries from Cleveland Clinic demonstrate for the first time how a testosterone-related genetic abnormality can help predict individual patient responses to specific prostate cancer therapies.
“The studies, published in the October 12 issue of JAMA Oncology, suggest that men who inherit this variant would benefit from a personalized treatment plan that targets specific hormonal pathways.”
“The first head-to-head comparison of docetaxel and abiraterone acetate for high-risk prostate cancer patients starting long-term hormone therapy found benefit with both treatments when added to androgen deprivation therapy (ADT). Treatment decisions may come down to specific toxicities, which differ between the treatments.
“The large STAMPEDE trial previously found that both docetaxel and abiraterone improved outcomes when compared with placebo. “Right now, oncologists and urologists want to know which combination is preferable, which is why we conducted this analysis,” said study author Matthew Sydes, MSc, a statistician at University College London.”
“Patients with high-volume, castration-naïve metastatic prostate cancer may have superior progression-free survival (PFS) outcomes when treated with early docetaxel, according to findings published online in the European Journal of Cancer.
“Using the Quality-adjusted Time Without Symptoms of disease and Toxicity of treatment (Q-TWiST) method, investigators also determined that the benefits associated with androgen deprivation therapy (ADT) plus docetaxel outweighed the risks associated with the treatment.”
“Combined therapy with abiraterone acetate/prednisone plus androgen deprivation therapy (ADT) significantly improved overall survival and radiographic progression-free survival (PFS) among men with metastatic hormone-naive prostate cancer compared with ADT and placebo alone, according to the results of the phase III LATITUDE trial (abstract LBA3) presented at the 2017 ASCO Annual Meeting.
” ‘In my opinion, these findings support the fact that adding abiraterone and prednisone to castration should now be considered the new standard of care for men with newly diagnosed metastatic prostate cancer,’ said researcher Karim Fizazi, MD, PhD, head of the department of cancer medicine at Gustave Roussy, University Paris-Sud, Villejuif, France.”
