IADT — pro and con; a follow-up

The other day we mentioned two articles in a recent issue of JAMA Oncology that dealt with the role of intermittent androgen deprivation therapy (IADT) in the management of progressive prostate cancer today. We have now had the good fortune to be able to read both of the two articles in full, thanks to a kind correspondent. … READ MORE …

Intermittent vs. continuous chemotherapy for men with CRPC

One of the small number of major prostate cancer presentations at the ASCO meeting this year comes from the so-called PRINCE trial of intermittent chemotherapy in men with castration-resistant prostate cancer (CRPC). … READ MORE …

CADT and IADT in the management of progressive and advanced prostate cancer

The debate over the relative values of continuous (CADT) and intermittent (IADT) forms of androgen deprivation therapy (ADT) in the treatment of advanced forms of prostate cancer has now been ongoing for years. … READ MORE …

Intermittent vs. continuous ADT: a therapeutic meta-analysis

According to the results from a new meta-analysis of data from 15 different clinical trials in nearly 7,000 patients in total, intermittent androgen deprivation therapy (ADT) is not inferior to continuous ADT with respect to the overall survival of patients. … READ MORE …

Intermittent vs. continuous ADT: the results of the ICELAND trial

The results of early, large, randomized trials of intermittent (IADT) vs. continuous androgen deprivation therapy (CADT) have provided conflicting results. However, one of the flaws in early trials was the failure to ensure that men enrolled into these trials all actually had an optimal initial response to androgen deprivation (ADT). … 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 …

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 …

Final data from S9346/INT-0162 published in NEJM this week

Last June, at the annual meeting of the American Society for Clinical Oncology, Hussain and colleagues presented data from the S9346/INT-0162 trial of continuous vs. intermittent androgen deprivation therapy in men with androgen-sensitive, metastatic prostate cancer. … READ MORE …

Four major advances in treatment of late stage prostate cancer in 2012

In a new paper in the Journal of Clinical Oncology, the American Society for Clinical Oncology (ASCO) has identified four significant advances in the treatment of late stage prostate cancer during 2012. … READ MORE …

IADT: the still unanswered questions and choices that must be made

About 18 months ago, at the 2011 Genitourinary Cancer symposium in Orlando, Florida, Klotz et al. presented data from a large trial of intermittent (IADT) versus continuous androgen deprivation therapy (CADT) in the management of men with progressive prostate cancer after prior treatment with first- or second-line radiation therapy. We reported their data at the time. … READ MORE …

IAD vs. CAD all over again: are you confused yet?

New data from the randomized FinnProstate Study VII trial comparing outcomes of men randomized to treatment with either intermittent (IAD) or continuous (CAD) androgen deprivation therapy are going to further confuse physicians and patients about the relative merits of these two types of androgen deprivation therapy. … READ MORE …

Interpreting the data from the S9346/INT-0162 trial in hormone-sensitive, metastatic disease

We have already reported data, presented by Dr. Maha Hussain yesterday, that appear to show that — at least in men with clearly metastatic prostate cancer — continuous and complete androgen deprivation (CAD) extends survival significantly better than intermittent androgen deprivation (IAD). … READ MORE …

IAD vs. CAD in men with hormone-sensitive, metastatic prostate cancer

Today at the ASCO annual meeting, Maha Hussein presented the results a long-term, international, randomized trial of intermittent androgen deprivation (IAD) versus continuous androgen deprivation (CAD) in men with hormone-sensitive, metastatic prostate cancer. … READ MORE …

Intermittent vs. continuous androgen deprivation therapy — expert comment

A new article offers expert perspective on the relative merits of intermittent and continuous androgen deprivation therapy (ADT) in the treatment of men with metastatic prostate cancer or recurrence of disease following first- or second-line treatment. … READ MORE …

Intermittent ADT “non-inferior” to continuous ADT in randomized Phase III trial

It has been suspected for many years that intermittent androgen deprivation (ADT) might have the same or a better impact on survival of prostate cancer patients as continuous ADT, with potentially superior effects on other factors such as quality of life. … READ MORE …
