Prostate CA risk factors:
Age
1. Rare in men of what age?
Race
- Higher rates in what race?
- Lower rates in what races? 2
Famil hx
4. Two fold greater risk with what?
Genetic
- Mutations especially with what?
- Men with what syndrome?
- Environmental causes?
Risk factors
Age
1. Rare in men younger than 40 y/o
-Develops in the 4th decade of life
Race
- Higher rates in African-American men
- Lower rate in
- Asian-American/
- Hispanic-Latino men
Family history
4. Two fold greater risk with first-degree relative
Genetic
- Mutations especially on BRCA2 increase risk in men
- Men with Lynch syndrome
- Environmental carcinogens
Agent Orange
Clinical presentation of prostate cancer?
6
- Men with early stage cancer usually have no symptoms
- Urinary frequency/urgency
- Nocturia
- Hesitancy
- Hematuria/Hematospermia
- Bone pain
Prostate cancer Dx?
4
- Physical exam/DRE
- Transrectal Ultrasound (TRUS)/MRI guided
- MRI
- Bone scan
What are you looking for on the DRE for prostate cancer?
3
- Nodules
- Induration
- Asymmetry
- Pathology: Prostate Cancer?
2. What are the zones of the prostate and state what percentage of cancer is found in each? 3
- Acinar cells of the prostate will develop into adenocarcinoma
- Zones of the prostate
- Peripheral zone (Majority of prostate cancer is found) 70%!
- Central zones (2-5% of prostate cancers are found)
- Transition zone (10-20% of prostate cancers are found)
PROSTATE CANCER
Describe the Gleason grade and staging?
Grading and Staging
Gleason grade
Scoring system using numbers 1-5
–Grade 1
Cancerous tissue looks like normal prostate tissue
–Grade 5
Cancer cells and growth patterns look very abnormal
Gleason grade
1. Different areas of the prostate have different what?
- Gleason grade (sum) adds what?
- Which ones?
Example
- Majority of the cancer is grade what?
- Less of the majority is grade what?
- 3 + 4 = Gleason grade __
- cancer grades
- two grades together
- Primary tumor and Secondary tumor - 3 (primary)
- 4 (secondary)
- 7
Staging
TMN system
describe the following:
1. Stage T1?
- Stage T2a and T2b?
- Stage T3?
- Stage T4?
- Stage N+ or M+?
- cancer is found in the prostate only. Cannot be felt by DRE or seen on imaging test
- a tumor that is to small to be felt or seen on image test (2a) or a slightly larger tumor that can be felt on DRE (2b)
- cancer has spread beyond the outer layers of the prostate into nearby tissues, and may have spread to seminal vesicles
- any tumor that has spread to other parts of the body
- Spread to lymph nodes or metastasized to other areas of the body
Prostate cancer risk classification: 1. Low risk?
- Intermediate risk?
- High risk?
- T1-T2a and gleason score less than or equal to 6 and PSA less than or equal to 10
- T2b and/or Gleason score 7 and/or PSA 10-20
- Greater than or equal to 8-10 or PSA greater than 20
Prostate CA Treatment?
5
Treatment
- Active surveillance
- Open Radical Prostatectomy vs MIRP (Gleason 6 and up)
- Radiation
- HIFU (High-Intensity Focused Ultrasound)
- Hormone therapy
Prostate cancer Tx:
1. Active surveillence at what staging level?
- When would you do Open Radical Prostatectomy vs MIRP?
- What are the kinds of radiation you could use? 3
- What kinds of hormone therapy? 2
- Gleason 6
- Gleason 6 and up
- External Beam
- High Dose Radiation (HDR)
- Brachytherapy
- Orchiectomy
- Androgen deprivation LHRH (Luteinizing Hormone-Releasing Hormone)
Testicular CA:
- Most common in what ages?
- Tumor spreads how? 2
- Prognosis?
- 90-95% of all primary tumors arise from what?
- Most common cancer in men between the age of 15-35 y/o
- Tumor spreads by lymphatics and blood
- Highly curable if discovered early
- 90-95% of all primary tumors arise from germ cells
Testicular CA
1. Germ cell tumor types? 2
- Non-germ cell tumors types? 2
- Germ cell tumors
- Seminomas (50%)
- Nonseminomas (more aggressive) - Non-Germ cell tumors (5%)
- Leydig cell
- Sertoli cell
