HIFU PHASE: Participants undergo mpMRI and CEUS pre-HIFU treatment and then CEUS post-HIFU treatment. Participants then undergo HIFU treatment over 2-2.5 hours.

PROSTATECTOMY PHASE: Within 2-4 weeks post-HIFU treatment, participants undergo mpMRI 1-2 days prior to radical prostatectomy. On the day of surgery, participants undergo CEUS prior to radical prostatectomy.

This phase II trial studies how well high-intensity focused ultrasound works in treating participants with intermediate and high-risk prostate cancer. High-intensity focused ultrasound uses high frequency sound waves to deliver a strong beam which may target and destroy a specific part of the prostate, while minimizing damage to surrounding structures and tissue.

PRIMARY OBJECTIVES:

I. Histologic assessment of cancer kill in the post high-intensity focused ultrasound (HIFU) needle biopsy and excised treated lobe 2-4 weeks after treatment with HIFU.

II. Radiologic assessment of areas suspicious for residual cancer in the treated lobe on multiparametric magnetic resonance imaging (mpMRI) and/or contrast enhanced ultrasound (CEUS) 2-4 weeks post-HIFU (immediately prior to radical prostatectomy).

SECONDARY OBJECTIVES:

I. Assessment of differences in tumor microenvironment, specifically upregulation of the immune system, before and after HIFU treatment on both the treated and untreated lobes.

II. Assessment of HIFU parameters needed to achieve dose-escalation, in the event that such escalation is needed per our study design.

OUTLINE:

HIFU PHASE: Participants undergo mpMRI and CEUS pre-HIFU treatment and then CEUS post-HIFU treatment. Participants then undergo HIFU treatment over 2-2.5 hours.

PROSTATECTOMY PHASE: Within 2-4 weeks post-HIFU treatment, participants undergo mpMRI 1-2 days prior to radical prostatectomy. On the day of surgery, participants undergo CEUS prior to radical prostatectomy.

After completion of study treatment, participants are followed up at 3 months.

High-Intensity Focused Ultrasound in Treating Participants With Intermediate and High-risk Prostate Cancer

Translation of High-intensity Focused Ultrasound (HIFU) or Treatment of Intermediate and High-Risk Prostate Cancer

Determined by calculating the mean percent of viable cancer tissue remaining after HIFU using two different measurements: histologic examination of excised prostate specimen and histologic examination of post HIFU needle biopsy. Each of these two measurements will be investigated independently using two types of analyses as follows: percent viable cancer in excised prostate specimen and percent viable cells using post-HIFU needle biopsy. Will calculate the mean percent viable cancer across patients along with a corresponding 95% confidence interval based on all 32 fully evaluable patients.

Determined by immunohistochemistry (IHC) and real-time polymerase chain reaction (RT-PCR). For this will use data collected from IHC on a panel of markers, obtained from both biopsy specimens obtained in the non-treated lobe at the time of biopsy (pre-HIFU) and right before RP (post-HIFU) revisiting them same pre-HIFU biopsy sites. Will compare mean IHC levels of each antibody examined in the pre-HIFU contralateral biopsy to the post-HIFU biopsy obtained from the same site. Mean IHC levels for each antibody will be compared using exact tests and analysis of variance.

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)"

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).

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

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

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.

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

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

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
