Phase I TrialTreat and Resect Protocol
To verify if MRgFUS ablation can determine necrosis of focal, locally non-advanced prostate cancer
and if these alterations can be identified using dynamic contrast enhanced (DCE) MRI.
Comparison with histopathology findings following RP
INCLUSION CRITERIA
• Patient of age between 50 to 75
• Patient with organ-confined Pca (cT1c and cT2a, N0, M0), diagnosed with TRUS biopsy (min:12 cores)
• Patient with PSA ≤ 10 ng/mL
• Gleason score 7 (3+4)
• Up to two (2) MR identifiable lesions
• No definite evidence of extracapsular extension
METHOD Prostate
EXCLUSION CRITERIA
• Patient under medications that can affect PSA for the last 3 months prior to MRgFUS treatment (Androgen Deprivation Treatment; alpha reductase inhibitors)
• Any rectal pathology, anomaly or previous treatment
• Identified calcification of 2 mm or more in largest diameter neighboring the rectal wall
• Bladder cancer
• Seminal vesicle/lymph node
• Prostate with multiple cystic lesions

Discussion
Focal Therapy for Prostate: are we ready?
• Identify Index Lesion• Long term efficacy• Follow-up• PSA level - limitation
Conclusion
MR guided Focused Ultrasound in
Locally non-advanced Prostate Cancer
• Safe - Effective - Well Tolerated
• Long Procedure Set-up
• Ready for Clinical Implementation
