Prostate video 2

  1. 1. Making Treatment Decisions for Prostate Cancer Robert Miller MD www.aboutcancer.com
  2. 2. Treating prostate cancer Surgery? Radiation?Or Watchful Waiting?
  3. 3. Choices with Prostate Cancer1. Depending on the man’s life expectancy and the nature of the specific cancer (Gleason score) is treatment necessary?2. If treatment is appropriate how to choose between surgery or radiation?
  4. 4. Watchful Waiting or Active Surveillance NCCN appropriate for: 1. Very low risk cancers and life expectancy < 20 y 2. Low Risk and life expectancy < 10 y
  5. 5. Very Low Recurrence Risk1. Stage T1c2. Gleason 6 or lower3. Less than 3 cores positive and none over 50%4. PSA density < 0.15 (so PSA was 5 and volume 35g then density would be 0.14 or 5/35)
  6. 6. Low Recurrence Risk 1. Stage T1 – T2a 2. Gleason 6 or lower 3. PSA < 10
  7. 7. Median Life Expectancy in Men by Health (poor, average or excellent)
  8. 8. Life Tables for Men in the US (2007 data) Age Expectancy 50 29 55 25 60 21 65 17 70 14 75 11 80 7.9 85 5.7
  9. 9. Watchful Waiting? Mortality if UntreatedGleason Score Death by 15 Years 2–4 4 – 7% 5 6 – 11% 6 18 – 30% 7 42 – 70% 8 – 10 60 – 87%
  10. 10. Watchful Waiting, the odds that untreated prostate cancerwould cause death related to the age and the Gleason Score
  11. 11. Laparoscopic Prostate Surgery
  12. 12. Laparoscopic Prostate Surgery The surgeon tries to dissect the prostate away from the rectum, bladder, the neurovascular bundle (nerves) and penile urethra
  13. 13. Radiation Fields with Prostate CancerA Low Dose Large Area (Phase 1) With radiation it is possible to include a wider area around the prostate to cover any cells that may have escaped After the highest safe dose is reached, the radiation target will be made smaller
  14. 14. Radiation Fields with Prostate CancerA High Dose Large Area (Phase 2) The final, high dose radiation target will be focused very precisely only on the prostate gland
  15. 15. NCCN.org
  16. 16. Prostate Cancer Risk Groupscombine all 3 things, the stage, thePSA level and the Gleason score•Low risk: (T1c, T2a Gleason 6, PSA <10)•Intermediate risk: (T2b, T2c, Gleason 7, PSA 10-20)•High risk: (T3, Gleason 8-10 or PSA > 20)
  17. 17. Cure Rates with Radiation versus Surgeryfor Early Stage Prostate Cancer are the same from the Cleveland Clinic.  Kupelian. JCO Aug 15 2002: 3376-3385
  18. 18. 10 Year Cure Rates for Patients with High Risk Prostate Cancer (PSA >20 or Gleason 8-10 or T3)Treatment Number Cure RateRadical 1,238 92%ProstatectomyRadiation plus 344 92%HormonesRadiation 265 88% Mayo Clinic Study (Cancer Jan 10, 2011)
  19. 19. Prostate Cures Rates by Treatment External beam > 72Gy Surgery or Seeds External beam < 72Gy IJROBP 2004; 58:25 Months
  20. 20. Prostate Cancer Relapse Rate by Radiation Dose < 72Gy 72 - 82Gy 82Gy Years Kupelian. IJROBP 2008:71:16
  21. 21. Cure Rates for High Risk Prostate Cancer Hormones + External + Seeds Surgery Seeds alone IJROBP 2006;66:1092 Months
  22. 22. Quality of Life / Medicare Survey Prostate Cancer PatientsSymptom Surgery RadiationWear Pads 30% 7%Potent (< 70y) 11% 33%Potent (>70y) 12% 27%More frequent bowel 3% 10%movements J Clin Oncol 14 (8): 2258-65, 1996

  24. 24. Potency Rates after Surgery can range from 2% to 70%) Did they have a ‘nerve sparing’ prostatectomy? Hold old is the man? How high was the PSA? How good was their sexual function before? JAMA. 2011;306(11):1205-1214
  25. 25. Potency Results after surgery from 2% to 70%)
  26. 26. Potency Results after External Radiation can range from 16% to 92% Did they get hormone therapy along with the radiation? How high was the PSA prior to radiation? How good was their sexual function before?
  27. 27. Potency Results after External Radiation can range from 16% to 92%
  28. 28. Potency Results after Seeds can range from 6% to 98% Patient Age? Race? Obese or thin? How good was their sexual function before?
  29. 29. Potency Results after Seeds range from 6% to 98%
  30. 30. Responded to ViagraSurgery: 60%External Radiation: 63%Seeds: 85% JAMA 2011:306:1205
  31. 31. Responded to Viagra Surgery: 43% Radiation: 70 –91% General Population: 80% from other studies in the literature
  32. 32. Choosing Treatment Prostate Cancer Urologist with experience and a good outcome experience with the procedureExperienced RadiationOncologist with ModernTechnology (IGIMRT) andgood outcome data
  33. 33. The experience of the surgeon is a criticalfactor associated with a successful outcomeOpen prostatectomy the learning curve didnot plateau until a surgeon had performed atleast 250 retropubic radical prostatectomiesThe probability of biochemical recurrence atfive years was significantly lower (10.7 versus17.9 percent)
  34. 34. Minimally invasive prostatectomy – In a seriesof 4,702 men who were managed withlaparoscopic prostatectomy by one of 29surgeons at seven centers,the five-year risk of recurrence progressivelydecreased with increasing experience (17, 16,and 9 percent with 10, 250, and 750 priorlaparoscopic procedures)
