1. ADT as primary therapy for localized PC | ||||||
Is there a role for ADT alone as primary therapy for patients with newly diagnosed, localized, asymptomatic PC? | 1 | 7 | 13 | 93 | 0 | 0 |
2. ADT as neoadjuvant and adjuvant therapy to RP | ||||||
Is there a role for neoadjuvant ADT with RP for low‐ to intermediate‐risk patients? | 0 | 0 | 13 | 93 | 1 | 7 |
Is there a role for neoadjuvant ADT with RP for high‐risk patients? | 1 | 7 | 10 | 71 | 3 | 22 |
Is there a role for adjuvant ADT following RP (N1, +/− EBR)? | 14 | 100 | ||||
Is there a role for adjuvant ADT following RP (N0, but other high‐risk features, absence of radiation)? | 0 | 0 | 12 | 86 | 2 | 14 |
Is there a role for ADT with radiation therapy? | 14 | 100 | ||||
Low‐risk patients (except for reduction of volume) | 14 | 100 | ||||
Intermediate‐risk patients (4‐6 months duration) | 14 | 100 | ||||
High‐risk patients (18‐36 months duration) | 14 | 100 | ||||
Timing: 1‐2 months before RT | 14 | 100 | ||||
For intermediate‐ and high‐risk PC patients, pending RT and ADT, we recommend ADT initiation ideally 1‐2 months before initiating RT | 14 | 100 | ||||
Given the natural history of PC (ie, about 1/3 of patients will go on to progress), the majority of patients with BCR should undergo observation with BCR. For the remaining patients (high risk), ADT would generally be considered for: | 14 | 100 | ||||
|
||||||
ADT in BCR is generally not recommended in patients with: | 14 | 100 | ||||
|
||||||
When considering ADT in high‐risk patients with BCR post‐RP, post‐RT, or postsalvage after RP, intermittent ADT is a reasonable alternative to continuous ADT | 12 | 86 | 2 | 14 | ||
Proposed Intermittent Treatment Pathway (Figure 1) | 13 | 93 | 1 | 7 | ||
There is level 1 evidence to support ADT use with salvage radiotherapy. It is reasonable to consider ADT in the setting of salvage radiotherapy as part of a shared decision‐making discussion. The duration of ADT in this setting is unclear, but 6‐12 months of ADT would be reasonable | 12 | 86 | 1 | 7 | 1 | 7 |
3. ADT for M1 HSPC and M1 CRPC | ||||||
In men with asymptomatic oligometastatic mCSPC (without visceral metastases), metastasis‐directed therapy may be a reasonable alternative to immediate ADT in select patients | 7 | 50 | 4 | 29 | 3 | 21 |
In mCSPC, continuous ADT is generally strongly preferred over intermittent ADT, however in certain circumstances (eg, cardiovascular comorbidities, intolerabilities, etc), intermittent may be considered | 13 | 93 | 1 | 7 | ||
In mCSPC, there are 3 options to achieve castration: bilateral orchiectomy, LHRH agonists, or LHRH antagonists | 13 | 93 | 1 | 7 | ||
CAB (ie, LHRHa, LHRHantag, +1st‐ or 2nd‐generation antiandrogen) is superior to castration alone | 9 | 64 | 5 | 36 | ||
In mCSPC, baseline T levels should be obtained before starting ADT | 14 | 100 | ||||
For ADT administration, testosterone level should be T < 20 ng/dL. Confirm castrate T levels 1‐4 months after surgical/medical castration, regardless of PSA levels. If PSA rises, T levels must be checked. If T levels are >20 ng/dL, clinicians should check luteinizing hormone levels to differentiate whether ADT was administered effectively | 14 | 100 | ||||
In mCSPC, if T > 20 ng/dL despite low luteinizing hormone levels, consider switching to an alternative agent | 14 | 100 | ||||
In the broad mCSPC population, ADT + Abi is superior to ADT alone in terms of OS | 14 | 100 | ||||
In mCSPC, the distinction between low‐ and high‐volume disease has not been studied in this context. Thus, ADT + Abi is a reasonable standard of care irrespective of metastatic burden | 12 | 86 | 2 | 14 | ||
In the broad mCSPC population, ADT + docetaxel is superior to ADT alone in terms of OS | 14 | 100 | ||||
|
||||||
In low‐volume mCSPC, there is evidence that ADT + docetaxel does not provide an OS benefit; thus, ADT + Abi is the favored choice | 13 | 93 | 1 | 93 | ||
In high‐volume mCSPC, there is strong evidence of benefit for ADT + docetaxel. Thus, both ADT + abiraterone or ADT + docetaxel are treatment options | 14 | 100 | ||||
The panel cannot comment on the comparative efficacy of ADT + Abi in low‐ vs high‐volume mCSPC, because this has not been studied | 14 | 100 | ||||
mCRPC is defined as: | 14 | 100 | ||||
mPC (by conventional radiology) | ||||||
Testosterone level <50 ng/dL | ||||||
Progressive disease (one or more of): | ||||||
|
||||||
In mCRPC, continuation of ADT to maintain T < 20 ng/dL is strongly recommended | 14 | 100 | ||||
Another reasonable option (“value‐based model”) in treating mCRPC is to stop ADT (once castrate levels are reached) and to check T levels q3 months, then restart ADT if T rises above >20 ng/dL | 2 | 14 | 6 | 43 | 6 | 43 |
For patients with mCRPC on treatment, testosterone levels should be measured: | 14 | 100 | ||||
|
||||||
Also, PSA and CT/bone scans should be performed at regular intervals | ||||||
4. AE Management Strategies with ADT | ||||||
Should a DEXA scan and FRAX score be obtained for baseline and follow‐up testing of bone fragility during treatment with ADT (pending approval by insurance provider)? | 14 | 100 | ||||
A DEXA scan should be obtained at baseline (within 6 months of initiating ADT) and at least once every 2 years for follow‐up | 14 | |||||
Vitamin D levels can be monitored in men taking osteoclast inhibitors, up to annually, or more often if replenishing depleted stores with high‐dose vitamin D. Daily maintenance doses for vitamin D supplementation should be 800‐1000 IU daily, and calcium daily maintenance dosing should not exceed 1200 mg daily | 13 | 93 | 1 | 7 | ||
The NCCN guidelines on determining which patients are eligible for additional pharmacologic therapy should be followed (ie calculating a patient's individual risk of fracture via FRAX calculator). For those patients who are eligible, zoledronic acid or denosumab can be used. | 14 | 100 | ||||
Either the urologist or the PCP should monitor blood pressure (at each visit), HbA1c (annually in nondiabetic patients), and lipid profile (annually) in patients receiving ADT | 13 | 93 | 1 | 7 | ||
Before initiating ADT, patients with CVD comorbidities should be referred to a cardiologist for comanagement | 14 | 100 | ||||
There is no evidence to support taking metformin to improve PC‐specific outcomes | 12 | 86 | 2 | 14 | ||
The urologist should communicate with the PCP or endocrinologist when patients with diabetes initiate ADT as they may need closer monitoring of diabetes | 12 | 86 | 2 | 14 | ||
HbA1c should be monitored up to annually by a cancer care provider or PCP in patients without a history of diabetes | ||||||
Cancer‐treating physicians should encourage physical activity/exercise, healthy diet, weight control, and smoking cessation in all patients on ADT throughout the course of their treatment | 14 | 100 | ||||
We recognize the importance of increasing urologists’ awareness of depression risk in patients receiving ADT | 14 | 100 | ||||
Urologists need to be aware of depression risk in patients receiving ADT | 14 | 100 | ||||
Consider routine discussions of mental health concerns, including questions about depression and memory concerns, with evaluation performed at least annually, in men receiving ADT | 14 | 100 | ||||
Patients over the age of 70 who have been on ADT for >2 years should be referred annually for neurocognitive assessment to evaluate for dementia | 4 | 29 | 3 | 21 | 7 | 50 |
We recognize hot flashes are side effects of ADT that can negatively impact patient quality of life. Of all the agents that are currently being used to treat hot flashes in men receiving ADT, none have an FDA approved indication for this use and each is associated with side effects. Shared decision‐making practices should be used to discuss the pros and cons of off‐label use of medications for hot flashes for men who wish to use medical management strategies | 14 | 100 |
