Overview
Brief Summary
A prospective, multicenter, parallel-group, open-label, randomized, phase II Clinical Study of Radiation Therapy, Hormone Therapy and Docetaxel Versus Radiation Therapy and Hormone Therapy in Patients with High-Risk Localized Prostate Cancer (Stage III and IV) whose primary objective is determine the percentage of patients free of biochemical recurrence within 5 years of receiving a combination of radiation therapy with docetaxel associated with hormone therapy or the standard of care of radiation therapy and hormone therapy in patients with stage III and IV localized prostate cancer with a poor prognosis.
Detailed Description
Randomized Phase II Clinical Study of Radiation Therapy, Hormone Therapy and Chemotherapy with Docetaxel Versus Radiation Therapy and Hormone Therapy in Patients with High-Risk Localized Prostate Cancer (Stage III and IV) Primary Objective: To determine the percentage of patients free of biochemical recurrence within 5 years of receiving a combination of radiation therapy with docetaxel associated with hormone therapy or the standard of care of radiation therapy and hormone therapy in patients with stage III and IV localized prostate cancer with a poor prognosis. Design: A prospective, multicenter, multidisciplinary, parallel-group, open-label study with randomized group assignment.

Outcomes
Primary Outcomes
Percentage of patients free of biochemical recurrence within 5 years of receiving a combination of radiation therapy with docetaxel associated with hormone therapy or the standard of care of radiation therapy and hormone therapy
Time Frame: 5 years of randomization
Percentage of patients free of elevation of PSA by 2 ng/mL above the minimum level reached since treatment (biochemical reccurrence), calculating the at-call event, i.e., the date of last confirmatory test (Phoenix criteria).
Secondary Outcomes

- Percentage of patients with progression-free survival(5 years)
- Percentage of patients with overall survival.(5 years)
- Clinical response rate(5 years)
- Biochemical response rate.(5 years)
- Quality of life of the patients(screening and week 9)
- Safety profile of the treatment.(5 years)
