MRI/Ultrasound Fusion Guided Prostate Cryotherapy

CLINICAL TRIAL OF OBSERVATION NATURE

PRIMARY OUTCOME

Cancer control of treated areas 5, 10, 15 years after intervention based on prostate biopsy of initial treated area, progression requiring conversion to radical prostate surgery or radiation or other forms of whole gland treatment (ej, HIFU), Metastatic Free survival: CT Scan and Bone Scans, Cancer-Specific and Overall Survival

SECONDARY OUTCOMES

Secondary Interventions focal interventions due to de-novo lesions. Focal or target therapy rescue with other technologies (ej HIFU); Short, Intermediate and Long-Term Urinary and Sexual Function changes in quality of life measured by validated inventories; Anxiety related to cancer and cancer control. Treatment tolerance to local anesthesia. Patient App compliance and activity to monitor care

DATA COLLECTION

Complete H&P, family history, past medical and surgical history, social history, allergies, and medications
As of July 2016, voluntary measurement thru Focalyx App for smartphones and tablets
Imaging Specifics Assessing Prostate, Seminal Vesicles and Urethral Contouring by Multi-parametric-MRI. Dominant lesions and secondary lesions contouring my MP-MRI.
Procedure specific Co-Registration quality with ultrasound denoting quality
Specific ablative description and digitalization of critical measures such as: ablation type (ej cryotherapy, equipment used) procedure, cryoprobes used, freeze/thaw cycles timing, temperatures at neurovascular bundles, denonvilliers fascia. Urethral warmer requirements
Follow up information: 30 day perioperative outcomes (incidence of UTI, urinary retention, failure of local anesthetic, pain measures). 6 week, 3,6,9,12 month and then every 6 month measures of PSA, Testosterone levels, Urinary Function and Sexual Function inventories, Overall anxiety and regret related to diagnosis and treatment
Uroflow and PVR measurements by 3 to 6 month of treatment
MP MRI on a yearly basis, for years 2,3,4 after treatment, biopsy driven by new suspicious MRI findings
MP MRI triggered by elevation in PSA velocity or PSA level 10% above diagnosis
Transperineal Fusion Guided Prostate biopsy at 1st year - emphasis on treated areas, suspicious MRI areas
Transperineal Fusion Guided Prostate biopsy at 5th year - emphasis on treated areas, suspicious MRI areas
5, 10, 15 Yr CT Scans, PET Scan/Bone Scan

SAFETY MEASURES

Periodic evaluation of registry to ensure consistency in follow up
Patient remainders of tests required
