observation

For very low-risk disease, the following criteria must be met: cT1c tumor, Grade Group 1, prostate-specific antigen (PSA) <10 nanograms/mL, <3 prostate biopsy fragments/cores positive, ≤50% cancer in each fragment/core, PSA density <0.15 nanograms/mL/g.[3]

Observation is recommended for patients with very low-risk disease with life expectancy <10 years. This involves monitoring the course of the disease with a view to delivering treatment or palliative therapy when symptoms arise or when there is a change in clinical findings that suggest symptoms are imminent.[3]

Observation should include a history and physical exam no more often than every 12 months (without prostate biopsies).[141] If patients become symptomatic, assessment should be performed (including prostate-specific antigen [PSA] and PSA doubling time, life expectancy estimate, and quality-of-life measures) to determine need for, and consideration of, treatment or palliation.[3]

androgen deprivation therapy alone (if symptomatic and life expectancy ≤5 years)

Patients with life expectancy ≤5 years who become symptomatic during observation can receive androgen deprivation therapy alone (a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist, or orchiectomy) for palliation.[3]

Advise patients about the risk of adverse effects with ADT, including rapid loss of bone mineral density, which increases the risk of osteoporosis and fractures.[150] Risk assessment for treatment-related bone loss is recommended for all patients starting ADT.[3][151] University of Sheffield: FRAX tool Opens in new window See Complications.

1st line –

active surveillance

If life expectancy is ≥10 years, active surveillance is recommended.[3]

Active surveillance involves monitoring the course of the disease (with additional use of prostate biopsies) until symptoms or signs of disease become clinically evident with the expectation to treat with definitive treatment if there is disease progression.

Patients can move to observation if their life expectancy decreases to <10 years.

PSA level and digital rectal exam are checked no more than every 6 and 12 months, respectively, unless clinically indicated.[3][141]

Repeat prostate biopsy and repeat multiparametric magnetic resonance imaging (MRI) are carried out no more often than every 12 months unless clinically indicated.[3] Intensity of active surveillance may be individualized based on patient and tumor factors, risk of progression, and life expectancy. However, most patients should have repeat biopsies every 2-5 years.

Confirmatory testing is recommended before starting active surveillance (within 6-12 months of diagnosis) if prebiopsy multiparametric MRI was not performed prior to diagnostic biopsy.[147] The role of confirmatory testing is to identify those at high risk for future disease upgrading or progression, and to ensure appropriate patients are selected for active surveillance.[147]

Confirmatory testing for active surveillance involves performing a multiparametric MRI (with PSA density calculation), if available, and/or biopsy (systematic and targeted), and/or molecular tumor analysis.[3][91][148] All patients should have a confirmatory prostate biopsy within 1-2 years of initial diagnostic biopsy.[3]

active surveillance

For low-risk disease, patients have all of the following and do not qualify for very low-risk disease: cT1-cT2a tumor, Grade Group 1, and prostate-specific antigen (PSA) <10 nanograms/mL.[3]

Patients with low-risk disease and life expectancy ≥10 years can delay definitive treatments (e.g., external beam radiation therapy, brachytherapy, or radical prostatectomy) and undergo active surveillance instead, depending on the patient's wish to avoid treatment-related adverse effects.[167][168][169]

Active surveillance is the preferred approach for most patients with low-risk disease if life expectancy is ≥10 years, but is often underutilized due to patient preference and lack of adherence.[179][180] Use of standardized patient information, clinician education, and guidelines may improve uptake of and adherence to active surveillance.[179] Factors that may increase the likelihood of regrading, and initiation of treatment, include high PSA density, ≥3 positive cores, high genomic risk, and/or a known BRCA2 germline mutation.[3]

PSA level and digital rectal exam are checked no more than every 6 and 12 months, respectively, unless clinically indicated.[3][141]

brachytherapy

For low-risk disease, patients have all of the following and do not qualify for very low-risk disease: cT1-cT2a tumor, Grade Group 1, and prostate-specific antigen (PSA) <10 nanograms/mL.[3]

Brachytherapy (low-dose rate or high-dose rate) is a treatment option for patients with low-risk disease and life expectancy ≥10 years.

Brachytherapy is a definitive treatment. The treatment goal is cure.

Low-dose rate brachytherapy involves the permanent transperineal implantation of radioactive sources into the prostate without any incision. The highest radiation dose is confined to the prostate and a small volume of surrounding tissue. The strength of radiation decreases over time, but low levels of radioactivity in the prostate will persist for 4-6 months depending on the half-life of the isotope used. Precautions should be taken in the short term to minimize close contact with pregnant women and small children.

High-dose rate brachytherapy involves the transperineal placement of treatment catheters through which an individual radioactive source is robotically placed temporarily at various dwell positions to achieve a conformal dose of radiation to the prostate. At the end of treatment the catheters are removed. Treatment is repeated up to five times to achieve a curative dose to the prostate.

external beam radiation therapy

For low-risk disease, patients have all of the following and do not qualify for very low-risk disease: cT1-cT2a tumor, Grade Group 1, and prostate-specific antigen (PSA) <10 nanograms/mL.[3]

External beam radiation therapy (EBRT) is a treatment option for patients with low-risk disease and life expectancy ≥10 years.

EBRT is a definitive treatment. The treatment goal is cure.

Several EBRT regimens have acceptable efficacy and toxicity, including moderate hypofractionation, conventional fractionation, and ultra-hypofractionation.[3][158][159][160] [ ]

Moderate hypofractionation is the preferred approach.[161] Although it shortens treatment duration, it may slightly increase the risk of acute gastrointestinal adverse effects compared with conventional fractionation.[158] Comparable biochemical control and toxicity have been reported with ultra-hypofractionation versus more protracted fractionation schedules, but higher total doses are associated with a greater risk of severe late genitourinary complications.[160]

Moderate hypofractionation or ultra-hypofractionation may be options across all risk groups; conventional fractionation is not recommended for low-risk or favorable intermediate-risk disease.[3]

Intensity-modulated radiation therapy and image-guided radiation therapy are the standard EBRT techniques because they allow for a highly conformal delivery of radiation that minimizes dose to normal tissues (bladder, rectum, and small bowel), thereby potentially decreasing toxicity to these structures. Stereotactic body radiation therapy is the technique used to deliver ultra-hypofractionated radiation therapy.

Biocompatible and biodegradable perirectal spacer materials can be implanted between the prostate and rectum in patients with organ-confined disease to reduce toxicity to the rectum.[3][156][157]

Patients with significant baseline urinary symptoms may not be suitable for EBRT due to increased risk of urinary obstruction.

1st line –

radical prostatectomy

For low-risk disease, patients have all of the following and do not qualify for very low-risk disease: cT1-cT2a tumor, Grade Group 1, and prostate-specific antigen (PSA) <10 nanograms/mL.[3]

Radical prostatectomy is a treatment option for patients with low-risk disease and life expectancy ≥10 years (depending on patient preference and suitability for surgery).

Radical prostatectomy is a definitive treatment. The treatment goal is cure.

Classically, the prostate and prostatic capsule are removed by excision of the urethra at the prostatomembranous junction. The seminal vesicles, ampulla, and vas deferens are also removed. Of the two classic open surgical approaches (retropubic/suprapubic and perineal), the retropubic/suprapubic approach is preferred by many urologists, as this approach facilitates access for pelvic lymph node dissection.

Laparoscopic and robotic-assisted radical prostatectomy are alternative approaches that typically involve five or six small incisions in the abdomen from which the entire prostate is removed, theoretically sparing nerves more easily damaged by a retropubic/suprapubic approach.[163][164] One Cochrane review found that laparoscopic or robotic-assisted radical prostatectomy may result in shorter hospital stays and fewer blood transfusions compared with open surgical radical prostatectomy, but improvements in oncologic outcomes (e.g., recurrence or survival) were inconclusive.[165] Complications (e.g., sexual and urinary dysfunction) appear to be similar between these alternative approaches and the open surgical approach.[165][166]

Radical prostatectomy in men with clinically localized prostate cancer that was not detected through PSA screening improves prostate cancer-specific mortality, overall survival, and risk of local disease progression and metastasis, compared with active surveillance.[167][168] These benefits have been shown to continue over the long-term, particularly in those ages ≤65 years.[169][170]

Radical prostatectomy in men with PSA-detected localized prostate cancer does not significantly reduce all-cause mortality or prostate cancer-specific mortality compared with active surveillance or observation.[171][172][173][174] Furthermore, radical prostatectomy is associated with a higher frequency of adverse events than active surveillance and observation.[171][172][173][174][175] [ ]

There is no standard approach to managing patients with intermediate-risk disease.

Brachytherapy boost (low-dose rate or high-dose rate) may be added to EBRT if there is concern about the ability to achieve local control with EBRT.[374] Brachytherapy alone may be an alternative option to EBRT for these patients.

High-dose radiation to the prostate and periprostatic tissue is recommended for patients who are candidates for radiation therapy plus ADT.[202][203][204][205][206] Dose escalation with EBRT alone or with the addition of brachytherapy boost to EBRT improves biochemical control, but increases toxicity.[207][208][209] Brachytherapy alone may achieve similar control (5-year freedom from progression) to EBRT plus brachytherapy boost in patients with intermediate-risk disease, but with lower toxicity.[210]

Targeted dose escalation techniques, using EBRT plus a micro-boost to the MRI-dominant lesion or an SBRT boost, may be a further option for select patients to improve biochemical control without increased toxicity.[3][211][212][213][214]

Androgen deprivation therapy (ADT) (e.g., a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist) may be given before, during, and/or after initiation of EBRT, for a total of 1.5 to 3 years.[216][217][218][219][220][221][222][223] A shortened duration of 1 year can be considered for patients having EBRT plus brachytherapy boost.[3][224]

The optimal duration of ADT for these patients remains controversial.[225] A significant improvement in disease-free survival is demonstrated for a longer duration of ADT in patients with high-risk disease.[218][225][226][227]

Use of combined radiation therapy with ADT significantly increases some treatment-related symptoms (e.g., pain with urination and overall urinary and bowel bother), although none are serious. However, given the substantial survival benefit of combined treatment, the increased risk of symptoms seems acceptable and has little extra effect on quality of life after 4 years compared with ADT alone.[228][229][230][231][232][233]

Advise patients about the risk of adverse effects with ADT, including rapid loss of bone mineral density, which increases the risk of osteoporosis and fractures.[150]

Abiraterone (a second-generation antiandrogen) is approved for use in metastatic disease. However, off-label use in combination with ADT (e.g., an LHRH agonist or antagonist) for 2 years, plus EBRT, is recommended for selected patients with very high-risk (nonmetastatic) disease.[3][239][240]

Abiraterone should not be used concurrently with another antiandrogen (e.g., nilutamide, bicalutamide, flutamide), and it should always be given with prednisone or methylprednisolone (depending on the formulation of abiraterone).

The addition of abiraterone to primary ADT has been shown to improve overall and failure-free survival in a randomized study of men with locally advanced prostate cancer (radiation therapy was required if node negative, and encouraged if node positive) or metastatic disease.[239] Overall survival data for the subgroup of patients with nonmetastatic disease at randomization are immature.[239] However, there are data showing improved metastasis-free survival in this subgroup.[241]

For very high-risk (locally advanced) disease, patients have at least two of the following: cT3-cT4 tumor; Grade Group 4 or 5; or PSA >40 nanograms/mL.[3]

Radical prostatectomy with pelvic lymph node dissection is a treatment option for highly selected patients with high-risk or very high-risk disease who are symptomatic or have a life expectancy >5 years (e.g., fit patients without tumor fixation to the pelvic musculature or skeleton), depending on patient preference and suitability for surgery.[3]

Radical prostatectomy is a definitive treatment. The treatment goal is cure.

androgen deprivation therapy alone (for patients unsuitable for surgery or radiation therapy)

Where possible, patients with high-risk or very high-risk disease should receive definitive treatment.[229] However, androgen deprivation therapy (ADT) alone (a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist, or orchiectomy) may be an option for patients who are unsuitable for definitive treatment due to medical comorbidities (e.g., inflammatory bowel disease or prior pelvic irradiation).[232]

ADT alone is not curative, but it may slow progression and help control symptoms.

ADT on an intermittent rather than a continuous basis may be considered, although whether this approach improves quality of life is controversial.[236][237][238]

Postoperative salvage therapy is indicated for patients with life expectancy >5 years if there is prostate-specific antigen (PSA) persistence (PSA does not fall to undetectable levels) or recurrence (increase of previously undetectable PSA on two or more measurements or to PSA >0.1 nanograms/mL).[3][245]

Evaluation for distant metastases should be carried out (e.g., if the patient develops symptoms or PSA is increasing rapidly), which may include bone and soft-tissue imaging and prostate bed biopsy.[3]

Risk assessment (including use of nomograms) should be carried out to inform decision-making after radical prostatectomy. The Decipher (22-gene genomic classifier) molecular assay may be considered to aid decision-making discussions, along with clinical and pathologic information, PSA level, and PSA doubling time.[3][105][242][243][244]

Salvage external beam radiation therapy (EBRT) with or without androgen deprivation therapy (ADT) (e.g., a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist) is the preferred treatment option for postoperative salvage therapy.[3][246][247][248]

Combining ADT with salvage EBRT reduces the likelihood of progression and may improve survival outcomes compared with salvage EBRT alone, but decisions (including duration of ADT) should be individualized.[246][247][248][249]

Following a careful review of the balance of risks and benefits, monitoring for progression (physical exam and PSA every 3-6 months, and imaging for symptoms or increasing PSA) may be an alternative to salvage therapy in patients with PSA persistence or recurrence after radical prostatectomy (and in whom postoperative imaging studies for pelvic nodal recurrence and distant metastases were negative).[3][258]

Salvage radiation therapy is more effective when given at lower levels of PSA (≥0.1 to 0.2 nanograms/mL), and should be considered for detectable, rising PSA, and before PSA levels reach 0.5 nanograms/mL.[245][258]

Observation is recommended (instead of salvage therapy) in patients with life expectancy ≤5 years.[3][376]

Decisions about adjuvant treatment for patients with adverse pathologic features or detectable PSA, but without PSA persistence or recurrence, should be individualized based on risk assessment and patient preferences.

Risk assessment (including use of nomograms) should be carried out to inform decision-making after radical prostatectomy. The Decipher molecular assay (22-gene genomic classifier) may also be considered to aid decision-making discussions, along with clinical and pathologic information, PSA level, and PSA doubling time.[3][105][242][243][244]

Adjuvant radiation therapy may be considered for patients with positive margins, extracapsular extension (pT3 disease), seminal vesicle invasion, or detectable PSA, and with no lymph node metastases.[250][251][252][253]

Patients with multiple adverse features or lymph node metastases (regardless of PSA levels) may be offered salvage EBRT (with or without ADT) as for PSA persistence or recurrence.[3]

Randomized controlled trials have shown that early salvage EBRT results in similar biochemical control and event-free survival rates, and lower genitourinary toxicity, compared with immediate adjuvant EBRT.[254][255][256][257]

Salvage therapy is indicated for patients with life expectancy >5 years if there is prostate-specific antigen (PSA) recurrence or positive digital rectal exam after primary radiation therapy.

PSA recurrence after radiation therapy is defined as PSA increase of ≥2 nanograms/mL above the nadir PSA.[259] Evaluation for salvage therapy can also be considered if the PSA is increasing but has not reached 2 nanograms/mL above nadir.

Treatment decisions should be individualized, guided by risk stratification; PSA density, and bone and soft-tissue imaging should be performed.[3][260]

local secondary therapy (which may include salvage prostatectomy plus pelvic lymph node dissection, salvage cryotherapy, reirradiation [low- or high-dose rate brachytherapy, or stereotactic body radiation therapy], high-intensity focused ultrasound).

Salvage brachytherapy provides precise treatment for pathologically confirmed (e.g., using magnetic resonance imaging-guided biopsy) locally recurrent disease, therefore minimizing toxicity to adjacent organs. Use of salvage prostatectomy and salvage cryotherapy is limited by treatment-related adverse effects (e.g. erectile dysfunction).[263][264][265][266][267][268][269]

Patients with nonmetastatic castration-resistant prostate cancer are those with clinical, radiographic, or biochemical (PSA) progression despite treatment with androgen deprivation therapy (ADT), but who do not have metastases. These patients are at high risk for developing metastases, particularly if PSA doubling time (PSADT) is short (e.g., ≤10 months).

ADT with a luteinizing hormone-releasing hormone (LHRH) agonist or antagonist should continue in these patients to maintain castrate serum levels of testosterone, but further hormonal treatment may be added depending on the PSADT.[3]

If PSADT is >10 months, monitoring with continued ADT is the preferred option. A secondary hormone therapy can be added to ADT (if not previously used), although evidence of survival benefit is lacking. Secondary hormone therapy may include: ketoconazole plus hydrocortisone; a first-generation antiandrogen (e.g., nilutamide, bicalutamide, flutamide); or a corticosteroid (e.g., hydrocortisone, prednisone, dexamethasone).[3]

Ketoconazole may cause severe liver injury and adrenal insufficiency. It is contraindicated in patients with liver disease and expert guidance should be sought if used. Liver and adrenal function should be monitored before and during treatment.[273]

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

Patients with castration-sensitive metastatic disease include those with metastatic disease at presentation, and those who are not receiving androgen deprivation therapy (ADT) when metastatic disease develops (i.e., castration-naive).

Genetic testing (germline and somatic) should be carried out in all patients with metastatic disease (if not done previously) to inform prognosis and guide treatment decisions, including eligibility for clinical trials and suitability for novel targeted therapies.[283][284] See Diagnosis approach.

Combination therapy with ADT (e.g., a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist) plus a second-generation antiandrogen with or without docetaxel is recommended.[239][284][285][286][287][288][289][290][291][292][293][294][295][296] Decisions about treatment should take into account toxicity, disease volume, and timing of metastases.

Specific treatment options include:

ADT plus docetaxel and one of: abiraterone, apalutamide, darolutamide, or enzalutamide; or

ADT plus one of: abiraterone, apalutamide, darolutamide, or enzalutamide.[3][240][296][299][300][301]

Abiraterone should always be given with prednisone or methylprednisolone (depending on the formulation of abiraterone).

For patients with high-volume disease (i.e., visceral metastases and/or ≥4 bone metastases with ≥1 beyond the vertebral bodies and pelvis) or low-volume disease (i.e., nonregional lymph-node-only disease, or presence of <4 bone metastases without visceral/other metastasis) with synchronous metastases, ADT plus a second-generation antiandrogen with docetaxel should be considered.[3] Triplet combination therapy may improve survival compared with ADT plus docetaxel alone, particularly in those with high-volume castration-sensitive disease.[300][301][302][303][304]

For low-volume disease (i.e., nonregional lymph-node-only disease, or presence of <4 bone metastases without visceral/other metastasis) with metachronous metastases, ADT plus abiraterone, apalutamide, or enzalutamide is preferred.[3][305]

ADT is usually given continuously, but intermittent ADT may be considered if adverse effects occur with continuous ADT.[73][309][310][311][312][313]

A PSA level ≤0.2 nanograms/mL after 7 months of ADT is a strong predictor for longer overall survival in patients with castration-sensitive metastatic disease.[314]

ADT alone is not recommended for patients with castration-sensitive metastatic disease unless combination treatment is clearly contraindicated.[3]

Bilateral orchiectomy is an option for patients with castration-sensitive metastatic disease, but is rarely used.

LHRH agonists may cause an increase in testosterone levels during the first week of treatment (testosterone flare), which may exacerbate symptoms in patients with metastatic disease.[152][153][154] If an LHRH agonist is used in the metastatic setting, it should be combined with a first-generation antiandrogen for ≥7 days to avoid testosterone flare or, alternatively, an LHRH antagonist can be used for 1 month before transitioning to an LHRH agonist.[3][155]

Supportive care should be considered to manage complications and symptoms related to metastatic disease.

Systemic radiation therapy with the beta-particle emitters strontium-89 or samarium-153 can be considered for palliation in patients with symptomatic bone metastases without visceral metastases. Their use is purely palliative and has largely been superseded by radium-223, which confers a survival advantage.

Radiation therapy in palliative doses can be given to sites of painful bony metastasis. Radiation may include a single treatment or a 1- or 2-week course depending on normal tissue toxicity and patient convenience.[367] Studies do not show a consistent difference between regimens for pain control, but some have reported higher rates of re-irradiation in patients receiving single-fraction regimens (although the reason for this is unclear).[367][368][369][370] Stereotactic body radiation therapy (SBRT) may be considered instead of conventional palliative radiation therapy for some patients with painful bony metastases (e.g., with an Eastern Cooperative Oncology Group performance status 0 to 2, without neurological symptoms, and not receiving surgery).[367][371] Radiation may also be given to the pelvis, if previously untreated, in palliative doses to relieve obstructive symptoms or bleeding.

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

Androgen deprivation therapy (ADT) plus external beam radiation therapy (EBRT) to the primary tumor (with or without abiraterone, apalutamide, docetaxel, or enzalutamide) may be an option for some patients with castration-sensitive metastatic disease.[3][297][298] Decisions about treatment should take into account toxicity, disease volume, and timing of metastases.

Abiraterone should always be given with prednisone or methylprednisolone (depending on the formulation of abiraterone).

Improved survival has been demonstrated with EBRT plus ADT versus ADT alone in patients with low-volume castration-sensitive disease (i.e., nonregional lymph-node-only disease, or presence of <4 bone metastases without visceral/other metastasis).[304][306][307][308]

Moderate hypofractionation and ultra-hypofractionation are the preferred approaches for EBRT.[3][306]

Patients with significant baseline urinary symptoms may not be suitable for EBRT due to increased risk of urinary obstruction.

Luteinizing hormone-releasing hormone (LHRH) agonists may cause an increase in testosterone levels during the first week of treatment (testosterone flare), which may exacerbate symptoms in patients with metastatic disease.[152][153][154] If an LHRH agonist is used in the metastatic setting, it should be combined with a first-generation antiandrogen for ≥7 days to avoid testosterone flare or, alternatively, an LHRH antagonist can be used for 1 month before transitioning to an LHRH agonist.[3][155]

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

Patients with castration-resistant metastatic disease are those who develop metastatic disease despite achieving castrate levels of testosterone with primary androgen deprivation therapy (ADT) (e.g., a luteinizing hormone-releasing hormone [LHRH] agonist or antagonist).

ADT should be continued to maintain castrate levels of testosterone in patients with castration-resistant metastatic disease. Patients should be closely monitored for progression, and treatments added sequentially.[3]

Treatment options for patients with castration-resistant metastatic disease have expanded rapidly. Optimal sequencing of therapies following docetaxel or cabazitaxel and/or second-generation antiandrogen therapy is unclear. Treatment decisions should take into account patient goals and preferences, prior treatment exposures, the presence or absence of symptoms, the location of metastases, potential adverse effects, and the presence of certain biomarkers.[3]

Tumor testing for somatic homologous recombination repair (HRR) mutations, microsatellite instability (MSI)/mismatch repair (MMR) deficiency, and tumor mutational burden (TMB) should be carried out in patients with metastatic disease (if not done previously) to inform prognosis and guide treatment decisions, including eligibility for clinical trials and suitability for novel targeted therapies.[283][284] Re-evaluation of somatic testing may be considered if done previously.[3] Germline testing for HRR mutations is recommended if not done previously. See Diagnostic approach.

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

An autologous active cellular immunotherapy, sipuleucel-T may be an option for asymptomatic or minimally symptomatic patients with good functional status (e.g., an Eastern Cooperative Oncology Group performance status of 0 to 1).[3][342][343]

Sipuleucel-T is not recommended for patients with visceral disease and a life expectancy of less than 6 months, or patients with hepatic metastases.[3][342]

Continue supportive care to manage complications and symptoms related to metastatic disease. Patients with castration-resistant disease who have bone metastases should be offered treatment to prevent skeletal-related events. See Complications.

PARP inhibitor ± second-generation antiandrogen + continue androgen deprivation therapy + supportive care

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

PARP inhibitors are recommended for patients with homologous recombination repair (HRR) gene alterations; response may be greatest for BRCA1 and BRCA2 variants.[3]

Olaparib can be considered for patients with an HRR gene mutation who have had prior second-generation antiandrogen therapy.[3][240][335][336][337] Efficacy may vary depending on the genes involved; in one study, of patients with an alteration in one of 15 prespecified HRR genes, those with a BRCA1 or BRCA2 mutation appeared to derive the greatest survival benefit.[337]

Rucaparib can be considered for patients with a BRCA1 or BRCA2 mutation who have had prior second-generation antiandrogen therapy.[3][338][344][345] Rucaparib is not recommended for patients without a BRCA1 or BRCA2 mutation.[3][346]

Olaparib or niraparib may be used in combination with abiraterone (plus prednisone or methylprednisolone) for patients with a BRCA1 or BRCA2 mutation who have not received prior second-generation antiandrogen therapy.[3][347][348][349]

Talazoparib plus enzalutamide may be an option for patients with an HRR mutation who have not been treated in the castration-resistant setting, depending on treatments received before progression.[3][350][351]

Anemia, fatigue, and nausea are commonly reported with PARP inhibitors. Careful monitoring for anemia and renal and hepatic function is required.[3]

pembrolizumab + continue androgen deprivation therapy + supportive care

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

A programmed death receptor-1 (PD-1)-blocking monoclonal antibody, pembrolizumab may be considered for patients with mismatch repair deficient, (dMMR), microsatellite instability-high (MSI-H), or high tumor mutational burden-high (TMB-H) castration-resistant metastatic prostate cancer.[3][284]

Much of the evidence for this treatment is based on different tumor types; however, early phase trials report antitumor activity among specific subsets of patients with metastatic castration-resistant prostate cancer.[352][353][354][355]

Pembrolizumab may cause severe, life-threatening immune-mediated adverse reactions.[356]

lutetium (Lu-177) vipivotide tetraxetan + continue androgen deprivation therapy + supportive care

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

A radioligand therapeutic agent that delivers beta-radiation to prostate-specific membrane antigen (PSMA)-expressing cells and the surrounding microenvironment. Lu-177 vipivotide tetraxetan can be considered for patients with progression after second-generation antiandrogen therapy who have PSMA-positive castration-resistant metastatic disease.[3][240][357][358][359][284]

PSMA-PET imaging is required for patient selection. Gallium (Ga-68) PSMA-11, piflufolastat F-18, or flotufolastat F-18 may be used as radiotracers to detect PSMA expression and determine eligibility.[3][357][360]

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

Carbazitaxel plus carboplatin may be considered in combination with prednisone for patients with aggressive disease or unfavorable genomics (two or more defects in PTEN, TP53, and RB1).[361]

Adverse events may include fatigue, anemia, neutropenia, and thrombocytopenia.

radium-223 + continue androgen deprivation therapy + supportive care

The main treatment goals for metastatic disease are prolongation of survival while maintaining quality of life, and palliation of symptoms that may arise from metastatic tumor deposits.

A calcium mimetic that localizes to the bone and delivers radiation directly to bone metastases, radium-223 can be considered for patients with castration-resistant metastatic disease who have symptomatic bone metastases without visceral metastases.[3][364]

Radium-223 is associated with adverse events including anemia, neutropenia, thrombocytopenia, bone pain, and gastrointestinal disorders. There have also been reports of increased risk of fracture and deaths when used in combination with abiraterone plus prednisone.[365][366]

The European Medicines Agency (EMA) has restricted the use of radium-223 to symptomatic patients who have received two prior treatments for metastatic prostate cancer, or who cannot receive other treatments. It should not be used with abiraterone and prednisone or with other systemic cancer therapies (except hormone therapy).[366]

A careful assessment of risk of fractures should be carried out before, during, and after treatment with radium-223. Concomitant bisphosphonate or denosumab is recommended when radium-223 is prescribed.[3][366] See Complications.
