3D Prostate Mapping Biopsies HAS A SIGNIFICANT IMPACT ON PROSTATE CANCER MANAGEMENT GARY ONIK MD MATTHEW MIESSAU DAVID BOSTWICK MD
TRUS BX-Gold StandardStaging of PCa • TRUS Bx highly inaccurate for staging • Accurate stage and grade, effects therapeutic decisions • Watchful waiting • Choice of radiation therapy/brachytherapy alone • Addition of CHT to radiation • Suitability for RP • Appropriateness of focal therapy “lumpectomy”
CD-US false negative Normal CD-US 54 yr old Gleason 6, 1mm, Rt side One year WW Bilateral Gleason 8
Increasing Stage • 60 yr old • PSA 5.3, T1c • TRUS bx, • 1.3 mm, 1 core, left • Gleason 6 • Considering WW • 3D PMB • 78 cores • 14 cores positive bilat • I one, cancer into fat • T3
3D Mapping-Results • N=180 all previous TRUS bx, • ALL positive only one side TRUS BX • 3D-PMB shows that: • Bilateral cancer, (55%) • Increased Gleason score (22%) • Over 70% would have management changed • Morbidity- • hematuria (1.2%), • retention (7%)
Focal Therapy for Prostate Cancer The Male Lumpectomy
Local Control of PCa Matters!!!! • Accepted Theory-Mets already present • LOCAL CONTROL DOES NOT CHANGE SURVIVAL • Recent evidence to the contrary • Zelefsky MJ et al. “Higher radiation dose levels (better local control) improved biochemical tumor control and decreased risk of distant metastases.” Int J Radiat Oncol Biol Phys. 2008 Jul 15;71(4):1028-33. • Trock et al. “Salvage radiotherapy (better local control) administered within 2 years of biochemical recurrence was associated with a significant increase in prostate cancer-specific survival.”
Focal Therapy and Local Control Hypothesis: Focal Therapy with Cryo Provides better local control than RP or Rad • Superior treatment of ECE • Only treatment that can be repeated • Treatment rad failures • Achieved with significantly lower morbidity.
Superiority of Local Control-ECE • 74 yr old • PSA=200 ng/ml • Gleason 10 • 12 months, CHT resistant • 4 yrs Post op • PSA undetectable off CHT 3 yrs P/O
Superiority of focal Therapy/Retreatment 52 yr old, 6/2002, PSA 6.3, G6 left gland, Re TRUS bx rt side negative, left hemi cryo, PSA stable 6 years then rise, Mapping bx +, retreat, PSA .4 stable
Focal Therapy Results 100% local control, 8 patients retreated
Male Lumpectomy Results high RP/45% Lodde M, et al
FOCAL THERAPY MORBIDITYN=120 • CONTINENCE 100% • POTENCY 85% • Reproduced 2 published studies
CONCLUSION • In the patients who need treatment the most Focal therapy provides better local control of prostate cancer. This will translate into improved survival • Focal therapy, promises better cancer results with lower morbidity • It is now an obligation of the medical community to produce a randomized trial comparing focal ablation to Robotic RP
