Q

Management of low risk, localized ca?

A

ACTIVE SURVEILLANCE (may do radical prostatectomy, radiotx)

Measure serum PSA every 3rd month

Repeat prostate biopsy

27
Q

Q

Management of high risk, localized ca?

A

Radiotherapy

Prostatectomy

29
Q

FIRST line management of metastatic disease?

A

HORMONAL tx!

  • androgen suppression (castration, LHRH agonist)
  • hormonal manipulation (adding/withdrawing Flutamid)
30
Q

Tx of castrate-resistant ca (hormonal ineffective)?

A

CHEMOTHERAPY = TAXELS (docetaxel, cabacitaxel)
