Radiation-hormone and Docetaxel VS Radiation-hormone in Patients With High-Risk Localized Prostate Cancer

Spanish Oncology Genito-Urinary Group134 enrolled

Overview

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.

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

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).

Time frame: 5 years of randomization

Secondary Outcomes

Percentage of patients with biochemical recurrence-free survival

The duration of survival, in months, between randomization of the patient in the study and the date of recurrence by PSA. In the remaining patients, the last available follow-up will be taken as the last control

Time frame: 5 years

Percentage of patients with progression-free survival

The duration of survival, in months, between randomization of the patient in the study and the date of recurrence by PSA, clinical manifestations or death due to disease. In the remaining patients, the last available follow-up will be taken as the last control

Time frame: 5 years

Percentage of patients with overall survival.

Defined as the time that elapses, in months, between randomization of the patient in the study and the date of death, regardless of the cause. In the remaining patients, the last available follow-up will be taken as the last control.

Time frame: 5 years

Clinical response rate

The clinical response rate: percentage of patients with partial and complete response, according to RECIST criteria.

Time frame: 5 years

Biochemical response rate.

Biochemical response rate: percentage of patients with partial and complete response, according to PSA levels.

Time frame: 5 years

Quality of life of the patients

Change from baseline in the Quality of Life Questionnaire C30 scale (QLQ-C30) to week 9. The QLQ-c30 has five functional scales (physical, role, cognitive, emotional, and social); three symptom scales (fatigue, pain, and nausea and vomiting); and a global health and quality-of-life scale. They are assigned values between 1 and 4 (1: nothing, 2: a few, 3: enough, 4: a lot) according to the patient's responses to the item, only in items 29 and 30 are assessed with a score from 1 to 7 (1: terrible, 7: excellent). The obtained scores are summed and standardized and gets a score between 0 and 100

Time frame: screening and week 9
