No 15-year survival benefit associated with primary ADT in older men

In another paper just published on-line in JAMA Internal Medicine this week, the authors have provided additional data indicating — once again — the lack of any value of primary androgen deprivation therapy (ADT) in the management of early-stage, localized prostate cancer among older patients. … READ MORE …

What’s being presented at ASCO this year: II

A “first-of-its kind” quality of life study to be presented at ASCO this year is a year-long, randomized, three-arm trial of the value of “purposeful” physical exercise in the management of men on androgen deprivation therapy (ADT) for progressive prostate cancer. … READ MORE …

Deferred or immediate initiation of ADT in patients with PSA-only relapse

Abstracts of all papers to be presented at the upcoming annual meeting of the American Society of Clinical Oncology (ASCO) were made available for pre-meeting review yesterday. A paper on the appropriate timing of initiation of androgen deprivation therapy (ADT) was featured by ASCO in its related news conference. … READ MORE …

Efficacy of continuous ADT and correlation to nadir serum T levels

We had “missed” a poster presented at the recent meeting of the European Urology Association that appears to “put to bed” — in a positive fashion — the question of a relationship between nadir serum testosterone (T) levels in men on continuous androgen deprivation therapy (ADT) and the long-term effectiveness of continuous ADT. … READ MORE …

Primary ADT ineffective for most men with early stage prostate cancer

Data from a large, retrospective study, reported in the Journal of Clinical Oncology, suggest something that many expert clinicians and patients have long suspected … that early use of androgen deprivation therapy (ADT) alone is not an effective treatment for most men with early stage prostate cancer. … READ MORE …

Supervised exercise and prevention of ADT-related side effects

A small, randomized trial in a group of 60+ Australian patients has demonstrated that a supervised exercise program started at the same time as initiation of androgen deprivation therapy (ADT) can have multiple beneficial results, including (at least temporary) avoidance of known side effects of ADT. … READ MORE …

Quality of life in the first 2 years on ADT for non-metastatic patients

A forthcoming paper in the Journal of Urology has attempted to quantify the effects of androgen deprivation therapy (ADT) on the mental and emotional well-being of men with non-metastatic prostate cancer. … READ MORE …

Prevention of bone-related and metabolic complications of treatment for men on ADT

A new article from an Australian clinical research group in the journal Andrology addresses “the effectiveness of implementing standardized guidelines to mitigate metabolic and bone side effects of androgen deprivation therapy (ADT) in men with non-metastatic prostate cancer.” … READ MORE …

Radiation therapy, neoadjuvant ADT, and initial PSA response

New data from Zelefsky and his colleagues at Memorial Sloan-Kettering Cancer Center suggest that men who respond well to neoadjuvant androgen deprivation therapy (ADT) have better long-term outcomes after radiation therapy given with curative intent for localized prostate cancer. … READ MORE …

Australian researchers identify “castration-tolerant cancer-repopulating cells” in mouse model

According to a media release issued earlier today in Australia, “a study led by Monash University researchers has found prostate cancer cells that survive androgen withdrawal treatment. Previously unidentified, these cells are potential targets for future treatments.” … READ MORE …

Sipuleucel-T before or after ADT in men with biochemically recurrent disease?

A paper to be presented at the upcoming annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago is entitled, “A randomized phase II study evaluating the optimal sequencing of sipuleucel-T and androgen deprivation therapy (ADT) in biochemically recurrent prostate cancer (BRPC): immune results.” … READ MORE …

Expert opinion on ADT for CRPC today

As regular readers will be well aware, the implementation of varying types of androgen deprivation therapy (ADT) in hormone-sensitive and in castration-resistant forms of progressive prostate cancer is evolving. Five or so years from now we may be looking at a very different set of ways to use ADT than those we have been used to. … READ MORE …

Abiraterone acetate for men with metastatic disease and a sub-optimal response to ADT

The Southwest Oncology Group (SWOG) is very keen to complete the accrual of patients to a small, Phase II, pilot study of the use of abiraterone acetate (Zytiga) in the treatment of men with metastatic prostate cancer and a less than optimal response to standard androgen deprivation therapy (ADT). … READ MORE …

New meta-analysis endorses IADT for good responders to initial CADT

A new meta-analysis of data from nine large clinical trials suggests that, “There is fair evidence to recommend use of [intermittent] instead of [continuous androgen deprivation] for the treatment of men with relapsing, locally advanced, or metastatic prostate cancer who achieve a good initial response to androgen deprivation.” … READ MORE …

Over-use of neoadjuvant and concurrent ADT in combination with radiation therapy

As anyone who has had long-term androgen deprivation therapy is well aware, this type of treatment may be able to delay the onset or relieve the metastases and bone pain associated with progressive prostate cancer, but it is far from being benign — and comes with a wide spectrum of side effects that affect some patients very seriously. … READ MORE …
