NCT00452556

Brief Summary

The purpose of this study is to see if sequence inversion of Intensity - modulated Radiotherapy (IMRT) for prostate cancer, can improve the safety and deliverability of concurrent docetaxel chemotherapy with long - term hormonal therapy. The hypothesis is that inverting the traditional sequence of radiotherapy can delay the time to treatment - induced bowel toxicity.

Outcome Measures

Primary Outcomes (1)

  • To investigate if the inversion of sequencing of multi - phase, intensity - modulated radiotherapy (IMRT), for the treatment of patients with high - risk prostate cancer, can improve the delivery of concurrent, weekly Docetaxel chemotherapy, in conc

    3 years

Secondary Outcomes (3)

  • To investigate if the inversion of sequencing of multi - phase IMRT can improve the time to grade 2 or 3 gastrointestinal toxicity.

    3 years

  • total amount of Docetaxel that can be delivered

    3 years

  • quality of life in patients receiving concurrent, weekly Docetaxel chemotherapy, in concert with long - term androgen deprivation (LTAD).

    3 years

Study Arms (2)

Standard Radiotherapy Sequence Arm

ACTIVE COMPARATOR

Standard sequence of radiotherapy = whole pelvic lymphatics, proximal seminal vesicles, prostate (or prostate bed) first, then prostate/prostate bed last

Drug: DocetaxelDrug: Leuprolide Acetate (Eligard®)Radiation: Intensity-Modulated Radiotherapy

Experimental Radiotherapy Sequence Arm

EXPERIMENTAL

Experimental sequence of radiotherapy = whole pelvic lymphatics, proximal seminal vesicles, prostate (or prostate bed) last, prostate/prostate bed first

Drug: DocetaxelDrug: Leuprolide Acetate (Eligard®)Radiation: Intensity-Modulated Radiotherapy
