GU CANCERS Flashcards
2nd most common cancer in men in america
prostate cancer
most common type of prostate cancer
adenocarcinoma
most aggressive type of prostate cancer
small cell carcinoma
RISK FACTORS FOR PROSTATE CANCER
⦁ Age: rare in men < 40; develops in 4th decade of life
⦁ Race: higher rates in African-American men, lower in asian-american / hispanic-latino men
⦁ Family Hx: 2x greater risk with 1st degree relative
⦁ Genetics: Mutations especially on BRCA2 & men with Lynch syndrome
prostate cancer associated with what environmental carcinogen used in military
Agent Orange
men with early stage prostate cancer symptoms
usually don’t have symptoms!
symptoms of prostate cancer
⦁ urgency / frequency ⦁ nocturia ⦁ hesitancy ⦁ hematuria / hematospermia ⦁ bone pain (mets)
diagnosis of prostate cancer
- DRE (nodules, induration, asymmetry)
- TRUS
- MRI
- Bone scan
pathology of prostate cancer = looking for _____ cells
ACINAR CELLS
will develop into Adenocarcinoma
what are the 3 zones of the prostate, and which zone is where the majority of prostate cancers are found
1) peripheral = where majority of prostate cancer is found
2) central (least amount found here)
3) transition
which prostate zone is where the majority of prostate cancers are found
peripheral
what grade system is used to grade prostate cancer
Gleason grading scale (grade 1-5)
⦁ grade 1 = where the cancerous tissue looks like normal prostate tissue
⦁ grade 5 = cancer cells & growth patterns look very abnormal
gleason grading scale
⦁ grade 1 = where the cancerous tissue looks like normal prostate tissue
⦁ grade 5 = cancer cells & growth patterns look very abnormal
- different areas of the prostate can have different cancer grades = so add the grades together
ex: if primary tumor (where majority of cancer cells are located) = grade 3, and if secondary tumor = grade 4, then have a Gleason grade 7
Need to biopsy the prostate to get a gleason grade; if take multiple biopsies from the primary tumor and they have different gleason grades, then take the higher score
a gleason score of 6 or less = usually more favorable & more slow growing
a gleason score of 8-10 = looking at more small cell cancer that is aggressive/fast growing
a gleason score of _________ = usually more favorable & more slow growing
6 or less!
a gleason score of 8-10 = looking at more small cell cancer that is aggressive/fast growing
PROSTATE CANCER TNM STAGING
-tumor / mets / nodes
⦁ Stage T1 = cancer only in prostate; can’t be felt by DRE or seen on imaging test
⦁ Stage T2a = tumor that is too small to be felt or seen on image test
⦁ Stage T2b = slightly larger tumor that can be felt on DRE
⦁ Stage T3 = cancer has spread beyond outer layers of prostate into nearby tissues, and may have spread to seminal vesicles
⦁ Stage T4 = any tumor that has spread to other parts of the body
Stage N+ or M+ = has spread to lymph nodes or has metastasized to other areas of the body
at which stage has prostate cancer spread beyond prostate into nearby tissues
stage 3
RISK CLASSIFICATION OF PROSTATE CANCER
⦁ Low risk = T1-T2A & Gleason score ≤ 6 and PSA ≤ 10
⦁ Intermediate Risk = T2b and/or Gleason score 7 and/or PSA 10-20
⦁ High Risk = ≥ T2c or Gleason score 8-10 or PSA > 20
low risk for prostate cancer
T1-T2A & Gleason score ≤ 6 and PSA ≤ 10
intermediate risk for prostate cancer
T2b and/or Gleason score 7 and/or PSA 10-20
high risk for prostate cancer
≥ T2c or Gleason score 8-10 or PSA > 20
SE of prostatectomy-
- urinary incontinence
- impotence / ED
- surgical risks - bleeding
Most common cancer in men between the age of 15-35 y/o
TESTICULAR CANCER
testicular cancer spreads by
lymphatics & blood
90-95% of all primary testicular cancer tumors arise from
germ cells
germ cell vs non-germ cell tumors of testicular cancer
90-95% of all primary tumors arise from germ cells
Germ cell tumors (more common than non-germ cell tumors)
⦁ Seminomas
⦁ Nonseminomas (more aggressive/ more common)
Non-Germ cell tumors
⦁ Leydig Cells
⦁ Sertoli Cells
