Intervention/exposure
Study type

Description of intervention(s) / exposure
Treatment: Surgery - Prostatectomy
Treatment: Other - Conventionally Fractionated Prostate Radiotherapy
Treatment: Other - Prostate SBRT

Active comparator: PACE-A: Prostatectomy vs prostate SBRT - Low and intermediate risk patients, for whom surgery is considered, will be randomised to prostatectomy vs prostate SBRT delivered with 36.25 Gy in 5 fractions.

Active comparator: PACE-B: Conventionally Fractionated RT vs Prostate SBRT - Low and intermediate risk patients, for whom surgery is not considered or who refuse surgery, will be randomised to either conventionally fractionated radiotherapy delivered to a dose of 78 Gy in 39 fractions or 62 Gy in 20 fractions vs SBRT delivered with 36.25 Gy in 5 fractions.

Active comparator: PACE-C: Conventionally Fractionated RT vs Prostate SBRT - Intermediate and high risk patients, indicated for 6 months ADT, will be randomised to either conventionally fractionated radiotherapy delivered to a dose of 60 Gy in 20 fractions vs SBRT delivered with 36.25 Gy in 5 fractions.


Treatment: Surgery: Prostatectomy
Radical prostatectomy: performed open, laparoscopically or using a robotically assisted laparoscopic approach.

Treatment: Other: Conventionally Fractionated Prostate Radiotherapy
Conventional fractionation delivered to a dose of:

(PACE-B) 78 Gy in 39 fractions or 62 Gy in 20 fractions; (PACE-C) 60 Gy in 20 fractions

Treatment: Other: Prostate SBRT
Prostate SBRT delivered to a dose of 36.25 Gy in 5 fractions.

Eligibility
Key inclusion criteria
Inclusion critieria (all arms):

* Histological confirmation of prostate adenocarcinoma within the last 18 months (unless on active surveillance and not clinically indicated)
* Men aged =18 years at randomisation
* WHO performance status 0 - 2
* Patients considered candidates for surgery are eligible for PACE-A; patients not considered candidates for surgery and patients who decline surgery or prefer to avoid surgery are eligible for PACE-B and PACE-C.
* Ability of the research subject to understand and the willingness to sign a written informed consent document.

Specific risk stratification inclusion criteria for PACE-A and PACE-B:

* Minimum of 10 biopsy cores.
* Gleason score = 3+4
* Clinical and/or MRI stage T1c -T2c, N0-X, M0-X
* PSA = 20 ng/ml (completed within 60 days of randomisation)
* Patients belonging to one of the following risk groups:
* Low risk - patients with tumours meeting all of the following criteria:

* Gleason = 6
* Clinical stage T1-T2a
* PSA < 10 ng/ml (within 60 days prior to randomisation)
* Intermediate risk - patients with tumours meeting any one of the following criteria:

* Gleason 3+4
* Clinical stage T2b or T2c
* PSA 10-20 ng/ml (within 60 days prior to randomisation)

Specific risk stratification inclusion criteria for PACE-C:

* Patient planned for a minimum of 6 months ADT (maximum of 12 months). Patients receiving extended androgen deprivation therapy (18 months maximum) to permit safe delay of radiotherapy as a result of the COVID19 pandemic (only) are eligible.
* Gleason score = 4+4
* MRI stage T1c -T3a, N0-X, M0-X
* PSA = 30 ng/ml (within 60 days prior to starting ADT)
* Patients belonging to one of the following risk groups:
* Intermediate risk - includes the presence of any of the following, assuming no high risk features apply:

* Gleason 7 (3+4 or 4+3)
* T2 (N0, M0-X)
* PSA 10-20 ng/ml
* High risk - patients with tumours that meet a maximum of 2 of the following criteria:

* Gleason 4+4 (max = 50% cores)
* T3a (N0, M0)
* PSA >20 ng/ml

Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria (all arms):

* Previous malignancy within the last 2 years (except basal cell carcinoma or squamous cell carcinoma of the skin), or if previous malignancy is expected to significantly compromise 5 year survival.
* Prior pelvic radiotherapy.
* Prior androgen deprivation therapy (including androgen agonists and antagonists) for PACE-A and PACE-B participants.
* Any prior active treatment for prostate cancer (with the exception of ADT for PACE-C participants). Patients previously on active surveillance are eligible if they continue to meet all other eligibility criteria.
* Life expectancy <5 years.
* Bilateral hip prostheses or any other implants/hardware that would introduce substantial CT artefacts.
* Medical conditions likely to make radiotherapy inadvisable eg inflammatory bowel disease, significant urinary symptoms.
* For patients having fiducials inserted: Anticoagulation with warfarin/ bleeding tendency making fiducial placement or surgery unsafe in the opinion of the clinician.
* Participation in another concurrent treatment protocol for prostate cancer.

Specific exclusion criteria for PACE-C:

* >14 weeks of androgen deprivation therapy prior to randomisation
* Medical conditions likely to make ADT inadvisable (e.g. significant and ongoing cardiac issues).
