Brief summary
The purpose of this study is see if quality of life is improved in patients receiving oral hormone therapy compared to standard of care. The study will also compare survival rates between patients receiving oral hormone therapy and those receiving standard of care.
Interventions
Bicalutamide 50 mg orally daily with either dutasteride or finasteride for 2 months. After two months of treatment bicalutamide with either dutasteride or finasteride will be taken along with radiation. After completion of radiation, bicalutamide will be stopped.
Dutasteride 0.5 mg orally will be taken daily with bicalutamide for 2 months. After two months of treatment dutasteride and bicalutamide will be taken along with radiation. After completion of radiation, dutasteride will be taken alone for two years.
Finasteride 5 mg orally will be taken daily with bicalutamide for 2 months. After two months of treatment finasteride and bicalutamide will be taken along with radiation. After completion of radiation, finasteride will be taken alone for two years.
7-8 weeks of radiation with bicalutamide and either dutasteride or finasteride.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quality of Life Was Measured by the Expanded Prostate Cancer Index Composite (EPIC) Hormonal Health-related Quality of Life Questionnaire | Baseline, 6 months, and 24 months | Questionnaires were completed in writing by the patient. Questionnaires were administered at 1-2 months after initiation of hormonal treatment (before RT), at 3-4 months (during RT), and at 6 months after initiation of study therapy. Patients also completed questionnaires at 12, 18, and 24 months after completion of radiation therapy. Of primary interest were the baseline and 6 month and 24 month timepoints which are reported here. Scale scores could range from 0-100, with higher scores indicating better quality of life. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Free From Biochemical Failure | 4 years | Increase in prostate-specific antigen (PSA) measured over time. Freedom from biochemical failure (FFBF) was defined from the time of enrollment until PSA failure occurs as defined by the Phoenix definition of a rise to 2 ng/mL above the nadir PSA value. |
