Focal Therapy Basics Flashcards
What is the % breakdown between multifocal tumors and unifocal tumors
75/25
Morbidity risks when patient has multifocal tumors
- unitary and sexual morbidity
what 3 advacements have changed ability to localize and risk stratify prostate cancer
- Advances in imaging
- Target BX
- Genomic testing
Patient population addressed by focal therapy
- Low Risk
- Favorable/intermediate
- Salvage therapy
Approximatly how many Focal One procedures to date
greater than 50,000
Focal therapy represents the valence between A/B
A. Active survailence
B. Overtreament (radical)
Focal therapy needs_______to ablate tissue in the designated area
controlled energy
What are the two pillars of focal therapy
- Localization
- Precision ablation
4 key pillars of Focal One system
- Fully robotic
- HIFUsion software to fuse MRI/BX
- Integrated, portable workstation
- Dynamic focusing
Dynamic focusing is
Allows for real time inmaging while delivering treatment and the most advanced HIFU tech to pinpoint target and deliver the energy avoding critical structures
Pre-treatement Planning Step 1
- Load images
- Edit contour and target areas
Pre-treatement planning step 2
Import BX volumes
Pre-treatement planning step 3
Real-time ultrasound volume, aquire US volume and edit P contour
Pre-treatment planning step 4
MRI/BX/US elastic fusion
Pre-treatement planning step 5
Treatment area planning
3 goals of planning the treatment area
- Precise contouring to area
- visualization of MRI and 3D BX
- Automatic dispatch of individual lesions
Max ablation depth A-P
40mm
How many focal points can be targeted in a slice
8
This componet has 15 rings, independently power supplied
Spherical Transducer
How many independantly power-supplied on a spherical transducer
16
How deep is the natural focal point
60mm
5 advantages of dynamic focusing
- Access anterior prostate
- More homogeneous lesions
- Faster treatment
- conformational treatmen to fit lesions/miss criticals
- Customizable for focal, multi, hemi of full gland
Allows ability to pause and modiffy planning on current slice
treatment tracking
Tracks the process of the overall treatement with virtual #d Prostate
Treatment Tracking
Focal/partial ablation patient type 4
- Intermediate Risk (G 7)
- Umnilateral cancer
- Patients wants to perserve function
- No need for TURP
How long is catheter in place after focal treatement
2-7 with mean of 5
Whold gland treatment patient procedure 3
- Over 70
- Bilateral disease
- TURP is perferred, 1 month before or during treatment
Whole gland and salvage catheter protocol
2-7 days, 5-7 ideal
Patient profile, Salvage 4
- BX proven recurrance
- No mets
- Pas less 4 an no hormon treatment
