Prostate 2 Flashcards
What are four very high risk features of prsotate cancer?
cT3b-T4
Primary Gleason 5
2 or 3 high risk features
>4 cores with GG4 or 5
What are three high risk features in prostate? How many do you need to qualify as high risk?
Exactly one of:
cT3
GG4 or GG5
PSA >20
How to differentiate unfavorable intermediate vs favorable?
Unfavorable has GG3 or >50% biopsy cores positive
Favorable has GG 1-2 or <50% cores positive
Unfavorable also has 2 or 3 intermediate risk factors vs 1 (T2b=T2c, GG 2 or 3, PSA 10-20)
When to order bone scan or soft tissue imaging in newly diagnosed prostate cancer?
Unfavorable intermediate risk or higher
who is appropriate for active surveillance?
Very low risk with 10-20 year survival
low risk with at least 10 year survival
Definition of PSA recurrence after surgery?
PSA >0.1 or 2 or more increases
PSA persistence is never becoming undetectable
Definition of PSA recurrence after RT?
Increase by 2ng/mL above nadir
Preferred treatment strategy for de novo metastatic HSPC with high volume disease?
ADT + Docetaxel + Abiraterone/Darolutamide
Treatment options for de novo metastatic HSPC without high volume disease? (3)
ADT+ Abi, apa, enza
What is the effect on survival for radiation to oligometastatic disease?
Improves PFS
Treatment options for M0 CRPC (3)
ADT +
Apa
Enza
Daro
Which is more common in prostate cancer, BRCA2 or BRCA1?
BRCA2
4 PARPi that are approved for mCRPC
Olaparib
Rucaparib
Talazoparib +/- Enzalutamide
Niraparib + Abiraterone
Definition of high volume metastatic disesase
Visceral mets or
4 or more bone mets (at least one met beyond pelvis-vertebrae)
4 adverse findings to be seen on a prostatectomy specimen
POstiive margin
seminal vesicle involvement
extracapsular extension (pT3a)
Detectable PSA
What is the difference between adjuvant RT and observation then salvage RT in patients with adverse findings after prostatectomy?
More toxicity in adjuvant RT, no benefit in survival compared to salvage RT
What types of patients with mCRPC are candidates for Sipuleucel-T?
Asymptomatic or minimally symptomatic
No liver mets
ECOG 0-1
Treatment options (2) for unfavorable intermediate risk disease?
RP + PLND or
EBRT + ADT 4-6 months
Treatment for favorable intermediate disease with life expectancy >10 years (3)
Surveillance
EBRT
Prostatectomy +/- PLND
Treatment for high-risk prostate cancer?
EBRT + ADT (long term)
EBRT + ADT + Abi (if PSA >40)
RP + PLND
Patient with unfav intermed disease goes for upfront RP and PLND. Has extracapsular extension, positive margins, and 1 LN was positive. Treatment?
Adjuvant ADT + EBRT
Technically could observe but nobody does
Preferred treatment for mCRPC that has progressed on docetaxel and abi (or enza)?
Cabazitaxel
Indication for niraparib + abi?
mCRPC with BRCA mutation
Indication for olaparib+Abi
mCRPC with BRCA mutation
Indication for Talazoparib + Enza
mCRPC with HRR mutation (BRCA 1/2, ATM, CDK12, CHEK2, MLH1, PALB2, RAD51C)
Indications for enzalutamide + ADT in the biochemical recurrent setting
High risk:
PSADT <9 mon
PSA >2 above RT nadir or >1 after RP +/- postop RT
