Guideline Statements
Early Evaluation and Counseling
In patients with suspicion of advanced prostate cancer and no prior histologic confirmation, clinicians should obtain tissue diagnosis from the primary tumor or site of metastases when clinically feasible. (Clinical Principle, )
322859
Clinicians should discuss treatment options with advanced prostate cancer patients based on life expectancy, comorbidities, preferences, and tumor characteristics. Patient care should incorporate a multidisciplinary approach when available. (Clinical Principle, )
322859
Clinicians should optimize pain control or other symptom support in advanced prostate cancer patients and encourage engagement with professional or community-based resources, including patient advocacy groups. (Clinical Principle, )
322859
Biochemical Recurrence without Metastatic Disease after Exhaustion of Local Treatment Options
Prognosis
Clinicians should inform patients with PSA recurrence after exhaustion of local therapy regarding the risk of developing metastatic disease and follow such patients with serial PSA measurements and clinical evaluation. Clinicians may consider radiographic assessments based on overall PSA and PSA kinetics. (Clinical Principle, )
322859
In patients with PSA recurrence after failure of local therapy who are at higher risk for the development of metastases (eg, PSADT <12 months), clinicians should perform periodic staging evaluations consisting of cross-sectional imaging (CT, MRI) and technetium bone scan, and/or preferably PSMA PET imaging. (Clinical Principle, )
322859
Clinicians should utilize PSMA PET imaging preferentially, where available, in patients with PSA recurrence after failure of local therapy as an alternative to conventional imaging due to its greater sensitivity, or in the setting of negative conventional imaging. (Expert Opinion, )
322859
Treatment
For patients with a rising PSA after failure of local therapy and no demonstrated metastatic disease by imaging, clinicians should offer observation or clinical trial enrollment. (Clinical Principle, )
322859
ADT should not be routinely initiated in this population (Expert Opinion). However, if ADT is initiated in the absence of metastatic disease, intermittent ADT may be offered in lieu of continuous ADT. (RecommendationB)
322859
Metastatic Hormone-Sensitive Prostate Cancer
Prognosis
Clinicians should assess the extent of metastatic disease (lymph node, bone and visceral metastasis) in newly diagnosed mHSPC patients. (Clinical Principle, )
322859
In newly diagnosed mHSPC patients, clinicians should assess the extent of metastatic disease (low- versus high-volume). High-volume is defined as greater than or equal to four bone metastases with at least one metastasis outside of the spine/pelvis and/or the presence of visceral metastases. (Moderate, B)
322859
Clinicians should assess if a newly diagnosed mHSPC patient is experiencing symptoms from metastatic disease at the time of presentation to guide discussions of prognosis and further disease management. (Recommendation, B)
322859
Clinicians should obtain a baseline PSA and serial PSAs at three- to six-month intervals after initiation of ADT in mHSPC patients and consider periodic conventional imaging. (Clinical Principle, )
322859
In patients with mHSPC, clinicians should offer germline testing, and consider somatic testing and genetic counseling. (Clinical Principle, )
322859
Treatment
Clinicians should offer ADT with either LHRH agonists or antagonists or surgical castration in patients with mHSPC. (StandardB)
322859
In patients with mHSPC, clinicians should offer ADT in combination with either androgen pathway directed therapy (abiraterone acetate plus prednisone, apalutamide, enzalutamide) or chemotherapy (docetaxel). (Strong, A)
322859
In selected mHSPC patients with low-volume metastatic disease, clinicians may offer primary radiotherapy to the prostate in combination with ADT. (Moderate, C)
322859
Clinicians should not offer first generation antiandrogens (bicalutamide, flutamide, nilutamide) in combination with LHRH agonists in patients with mHSPC, except to block testosterone flare. (StandardA)
322859
Clinicians should not offer oral androgen pathway directed therapy (e.g., abiraterone acetate plus prednisone, apalutamide, bicalutamide, darolutomide, enzalutamide, flutamide, nilutamide) without ADT for patients with mHSPC. (Expert Opinion, )
322859
In selected patients with de novo mHSPC, clinicians should offer ADT in combination with docetaxel and either
abiraterone acetate plus prednisone (Strong, A)
322859
darolutamide (Strong, B)
322859
Non-Metastatic Castration-Resistant Prostate Cancer
Prognosis
In nmCRPC patients, clinicians should obtain serial PSA measurements at three- to six-month intervals, and calculate a PSADT starting at the time of development of castration-resistance. (Clinical Principle, )
322859
Clinicians should assess nmCRPC patients for development of metastatic disease using conventional or PSMA PET imaging at intervals of 6 to 12 months. (Expert Opinion, )
322859
Treatment
Clinicians should offer apalutamide, darolutamide, or enzalutamide with continued ADT to nmCRPC patients at high risk for developing metastatic disease (PSADT ≤10 months). (StandardA)
322859
Clinicians may recommend observation with continued ADT to nmCRPC patients, particularly those at lower risk (PSADT >10 months) for developing metastatic disease. (Clinical Principle, )
322859
Clinicians should not offer systemic chemotherapy or immunotherapy to nmCRPC patients outside the context of a clinical trial. (Clinical Principle, )
322859
Metastatic Castration-Resistant Prostate Cancer
Prognosis
In mCRPC patients, clinicians should obtain baseline labs (e.g., PSA, testosterone, LDH, Hgb, alkaline phosphatase level) and review location of metastatic disease (bone, lymph node, visceral), disease-related symptoms, and performance status to inform discussions of prognosis and treatment decision making. (Clinical Principle, )
322859
In mCRPC patients, clinicians should assess the extent of metastatic disease using conventional imaging at least annually or at intervals determined by lack of response to therapy. (Expert Opinion, )
322859
In patients with mCRPC, clinicians should offer germline (if not already performed) and somatic genetic testing to identify DNA repair deficiency, microsatellite instability (MSI) status, tumor mutational burden, and other potential mutations that may inform prognosis and familial cancer risk as well as direct potential targeted therapies. (Clinical Principle, )
322859
In mCRPC patients without PSA progression or new symptoms, clinicians should perform imaging at least annually. (Expert Opinion, )
322859
In mCRPC patients with disease progression (PSA or radiographic progression or new disease related symptoms) having previously received docetaxel and androgen pathway inhibitor, who are considering Lu-PSMA-617, clinicians should order PSMA PET imaging. (Expert Opinion, )
322859
Treatment
In newly diagnosed mCRPC patients who have not received prior androgen receptor pathway inhibitors, clinicians should offer continued ADT with
abiraterone acetate plus prednisone (Strong, A)
322859
docetaxel (Strong, B)
322859
enzalutamide. (Strong, A)
322859
In mCRPC patients who are asymptomatic or minimally symptomatic, clinicians may offer sipuleucel-T. (RecommendationB)
322859
Clinicians should offer radium-223 to patients with symptoms from bony metastases from mCRPC and without known visceral disease or lymphadenopathy >3cm. (StandardB)
322859
In sequencing agents, clinicians should consider prior treatment and consider recommending therapy with an alternative mechanism of action. (Moderate, B)
322859
In mCRPC patients who received prior docetaxel chemotherapy with or without prior abiraterone acetate plus prednisone or enzalutamide for the treatment of CRPC, clinicians may offer cabazitaxel. (Moderate, B)
322859
In mCRPC patients who received prior docetaxel chemotherapy and abiraterone acetate plus prednisone or enzalutamide, clinicians should recommend cabazitaxel rather than an alternative androgen pathway directed therapy. (StandardB)
322859
Clinicians should offer a PARP inhibitor to patients with deleterious or suspected deleterious germline or somatic homologous recombination repair gene-mutated mCRPC following prior treatment with enzalutamide or abiraterone acetate, and/or a taxane-based chemotherapy. Platinum based chemotherapy may be offered as an alternative for patients who cannot use or obtain a PARP inhibitor. (RecommendationC)
322859
In patients with mismatch repair deficient or microsatellite instability high mCRPC, clinicians should offer pembrolizumab. (Moderate, C)
322859
Clinicians should offer Lu-PSMA-617 to patients with progressive mCRPC having previously received docetaxel and androgen pathway inhibitor with a positive PSMA PET imaging study. (Strong, B)
322859
Bone Health
Clinicians should discuss the risk of osteoporosis associated with ADT and should assess the risk of fragility fracture in patients with advanced prostate cancer. (Clinical Principle, )
322859
Clinicians should recommend preventative treatment for fractures and skeletal-related events, including supplemental calcium, vitamin D, smoking cessation, and weight-bearing exercise, to advanced prostate cancer patients on ADT. (Clinical Principle, )
322859
In advanced prostate cancer patients at high fracture risk due to bone loss, clinicians should recommend preventative treatments with bisphosphonates or denosumab and referral to physicians who have familiarity with the management of osteoporosis when appropriate. (Clinical Principle, )
322859
Clinicians should prescribe a bone-protective agent (denosumab or zoledronic acid) for mCRPC patients with bony metastases to prevent skeletal-related events. (RecommendationB)
