Objectives

Upon completion of this course, students will:

  1. recognize what percentage of all cancers in males are prostate cancers
  2. understand that the prevalence of prostate cancer increases with age, and that up to 70% of men 80 years and older have histologic evidence of prostate cancer
  3. realize that the 5 year survival rate for all stages of prostate cancer has been increasing for the last 25 years, and is now almost 99%
  4. know the local, minimally invasive options available for cancer confined to the prostate
  5. know the three dimensions in the accurate assessment of prostate cancer
  6. know what markers are currently used for prostate cancer screening
  7. know the lifetime risk of a diagnosis of prostate cancer for men
  8. know the risk of death from prostate cancer
  9. recognize what is considered clinically significant prostate cancer
  10. know what percentage of patients with mild elevation of PSA have the increased levels as a result of a benign condition
  11. know the definition of prostate density
  12. know the percentage of prostate cancers that are isoechogenic to normal parenchyma
  13. know the recommended time for repeat prostate biopsy after an initial biopsy is indicated by abnormal PSA levels, or other abnormal finding
  14. be familiar with the volume of the prostate gland that is extracted during a biopsy session
  15. compare transperineal with transrectal biopsy of the prostate
  16. know which method of prostate evaluation can provide spatial information about prostate cancer
  17. know what percentage of prostate cancers are underestimated by clinical staging
  18. know why MRI is ideally suited for evaluation of the prostate
  19. identify the MRI contrast agent that allows detection of almost all pathologically involved lymph nodes
  20. know the zonal anatomy of the prostate
  21. know which type of cancer makes up 95% of prostate cancers
  22. be familiar with the appearance of the capsule of the prostate on T2-weighted images
  23. understand the anatomy of the prostate and how it allows cancer to spread outside the prostate
  24. know how many grades make up the final Gleason score
  25. know the lowest Gleason score for cancer in the United States
  26. understand the value of T1-weighted imaging for the prostate
  27. know some criteria for extracapsular extension of prostate cancer
  28. know reasons for reduced diffusion in prostate cancer
  29. know that ADC is reduced in prostate cancer and by how much, compared to normal tissues
  30. understand what DWI reflects at high b-values
  31. be able to characterize lower b-value DWI images
  32. be familiar with the reason for increased ADC values in aging males
  33. list some reasons for susceptibility-induced distortions on DWI
  34. know the units for expressing chemical shift
  35. be able to name the chemical solution used as a reference for the null point in MR spectroscopy
  36. understand why adequate saturation bands around the prostate are important in MR spectroscopy
  37. be able to name two MR spectroscopic methods
  38. know the classic MR spectral signature of prostate cancer
  39. understand the behavior of prostate cancer during dynamic contrast-enhanced MR studies
  40. list tumor types that can be difficult to detect due to partial volume effect
