In locally advanced prostate cancer hormonal therapy often prolongs the suppression of the primary tumor by radiotherapy (RT), but the question remains whether hormonal therapy should be reserved for relapse or used early in asymptomatic patients with locally advanced disease who are receiving external RT. In this phase III Radiation Therapy Oncology Group (RTOG) trial, the researchers compared the clinical outcome of patients who received RT only with those who had RT plus long-term adjuvant goserelin.
A total of 945 patients with locally advanced prostate cancer were included. Of them 477 were randomized to the adjuvant hormone arm (Arm I) and 468 to the RT only arm (Arm II) with hormones. Goserelin (Zoladex) was started during the last week of RT on Arm I and at the time of relapse on Arm II.
Adjuvant treatment with goserelin, when started simultaneously with external RT, improves local control and reduces distant metastasis in patients with locally advanced prostate cancer. For subgroup of patients with Gleason Score of 8-10, addition of goserelin improves overall survival as well.Imprima English
Oct 31, 2014 - The risk of death from prostate cancer is lower for patients treated with brachytherapy supplemented by external-beam radiation therapy and androgen suppression therapy than it is for those treated with brachytherapy alone, according to a study published online July 13 in the Journal of Clinical Oncology.
