Radiation Therapy in Treating Patients With Prostate Cancer

2013년 12월 3일 업데이트: Medical Research Council

A Randomised Trial of High Dose Therapy in Localised Cancer of the Prostate Using Conformal Radiotherapy Techniques

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether standard radiation therapy is more effective than high-dose radiation therapy in treating patients with prostate cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of standard radiation therapy with that of high-dose radiation therapy in treating patients with stage II or stage III prostate cancer.

상세 설명

OBJECTIVES:

Compare local tumor control in patients with stage II or III prostate cancer treated with neoadjuvant androgen deprivation therapy with standard vs high-dose conformal radiotherapy.
Compare the incidence of biochemical failure (prostate-specific antigen (PSA) greater than 2 ng/mL at 6 or more months after initiation of radiotherapy and PSA rising from nadir level by at least 50%), development of metastases, and survival in patients treated with these regimens.
Compare the acute and late radiation-induced side effects of these regimens in this patient population.
Compare aspects of quality of life, health economics, models of normal tissue, and tumor control in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to prostate-specific antigen, T stage, and Gleason score. Patients are randomized to one of two treatment arms.

All patients receive neoadjuvant androgen deprivation with luteinizing hormone-releasing hormone agonists every 4 weeks beginning 3-6 months before initiation of radiotherapy and continuing until completion of radiotherapy.

Arm I: Patients undergo standard conformal radiotherapy for 6.5 weeks.
Arm II: Patients undergo high-dose conformal radiotherapy for 7.5 weeks. Quality of life is assessed at baseline, every 6 months for 2 years, and then annually thereafter.

Patients are followed every 6 months for 2 years and then annually thereafter.

PROJECTED ACCRUAL: A total of 800 patients will be accrued for this study.
