Metastatic Castration-Resistant Prostate Cancer (mCRPC)
Testosterone ≤1.7 nmol/L AND metastasis detected with conventional imaging (with or without PSA progression)
• Conduct staging and prognostic assessment
• Assess for HRR gene mutations (BRCA1/2 or ATM)
• Consider multidisciplinary consult and clinical trial participation
Continue ADT [L3sr]
• Initiate denosumab or zoledronic acid [L1SR], with Vit D and calcium for prevention of SREs
Poor Prognosis Moderate/Good Prognosis
• See Halabi (JClinOncol. 2014) criteria for prognostic • Choice of therapy should generally exclude agents and drug classes received in the past
stratification • Optimal treatment sequence remains unknown
• Widespread visceral metastasis, rapid progression
of clinical symptoms, poor response to ADT, radiological mCRPC 1 -Line (preference for agents not received in the past)

a. Abiraterone 1000 mg/day plus prednisone 5 mg BID. Clinical trial
b. The timing of docetaxel therapy in men without symptoms should be discussed
with patients, and therapy should be individualized based on the patient’s clinical
status and preference. Clinical, radiological, or PSA progression e,f
c. Radium-223 is recommended in patients with pain due to bone metastases and
who do not have visceral metastases. Radium 223 significantly improved overall
survival and reduced symptomatic SREs in patients who previously received mCRPC 3 -Line (preference for agents not received in the past)

d. The clinical trials of abiraterone acetate and enzalutamide in the chemo-naïve Cabazitaxel (post-docetaxel) [L1SR] OR
setting did not include patients with moderate or severe symptoms, however Radium-223 (if symptomatic and no visceral metastases)[L1SR] OR
these therapies may be considered in patients who refuse or are deemed
unsuitable for chemotherapy. Clinical trial OR
e. PSA progression as defined by PCWG2 criteria (PSA increase that is ≥25% and Olaparib (if HRRm and prior ARAT) [L1SR] OR
≥2 ng/mL above the nadir, and which is confirmed by a second value 3 or more Docetaxel re-exposure (unknown survival benefit) [EO] OR
weeks later). Mitoxantrone (unknown survival benefit) [EO]
f. Consider palliative options.
