What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial paper looks at Leuprolide and Goserelin.

Who Took Part

The age groups tagged for this paper are middle-aged adults, older adults and people over 80, men only.

One thousand five hundred seventy-nine men with intermediate-risk prostate cancer were randomly assigned to 8 weeks of AS followed by radiotherapy with an additional 8 weeks of concurrent AS (16 weeks total) or to 28 weeks of AS followed by radiotherapy with an additional 8 weeks of AS (36 weeks total).

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Leuprolide study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The timeline in the abstract includes 10 years.

Time-to-event end points are reported for up to 10 years of follow-up.

What Was Measured

Topics PubMed links to this paper include Androgen Antagonists, Anilides, Antineoplastic Agents, Hormonal, Antineoplastic Combined Chemotherapy Protocols, Chemoradiotherapy, Disease-Free Survival and Flutamide.

What This Means in Plain Language

The paper is a randomized study of Leuprolide and Goserelin over 10 years.

Our Notes on the Compounds

Leuprolide: A 9-amino-acid GnRH analog (Lupron, Eligard) that lowers sex-hormone levels with ongoing use; used in prostate cancer, endometriosis and early puberty.

Goserelin: A GnRH analog implant (Zoladex) used to lower sex-hormone levels in prostate and breast cancer and gynecologic conditions.
