Q

MOA
- Blocks conversion of testosterone to DHT (alpha 1 receptors)
- Decreased epithelial tissue in prostate

Indications
- Mechanical obstruction of urethra
- Works on enlarged prostate only

s/e
- Impotence
- Decreased libido
- Gynecomastia – abnormal growth breast tissue

Other notes
- Results 6-12 mos
- Take it for life
- Lowers DHT, doesn’t lower testosterone
- Males can’t donate blood while taking this med
- Decreases prostate specific antigen (PSA) levels
o measure PSA before starting drug and 6 mos after starting drug
o If PSA isn’t low = eval for prostate cancer
- Also used to treat male pattern baldness – increases hair growth
- Females caution in handling – tetragenic for preg. Women, may cause birth defect in male fetus

Prognosis
- Stage dependent
- Early diagnosis
- Severity depends on

Q

which cancer has controversy around screening - prostate or testicular cancer?

prostate

  • Most prostate cancer grows so slowly that men die of other causes before prostate cancer becomes deadly, making them clinically irrelevant
  • PSA antigen screening helps diagnosis
  • Benefits of PSA
    o Some survival benefit
    o Drop in prostate cancer death in US
  • Harms of PSA
    o Takes 48 diagnoses to prevent 1 death
    o 1 in 3 men with a positive PSA will have prostate cancer
    o Many unnecessary biopsies
    o s/e of unnecessary treatment – erectile dysfunction, urinary incontinence, bowel problems
