Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A large proportion of men with prostate cancer are overdiagnosed and overtreated mainly due to PSA testing. Active surveillance (AS) aims to reduce these harms by recommending curative treatment only when and if signs of tumor progression occur. There are however a number of uncertainties in AS, the most important being when to initiate treatment. The investigators are therefore starting a large randomized multicenter trial testing the safety of a standardized active surveillance protocol with specified triggers for repeat biopsies and initiation of curative treatment. The standardized protocol is compared with current practice for active surveillance. The primary aim of the study is to reduce overtreatment and subsequent side effects, without increasing the risk of disease progression or prostate cancer mortality.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

STUDY HYPOTHESIS

The study hypothesis is that standardized triggers for initiation of curative treatment of men who are in active surveillance will reduce overtreatment without increasing disease progression and prostate cancer mortality.

STUDY DESIGN

Randomized multi-centre open-label clinical trial

INTERVENTIONS

Computerized randomisation (1:1) within 12 months from diagnosis of prostate cancer, either to active surveillance according to current clinical practice at the trial centre (reference arm), or to a standardised active surveillance protocol applying specific criteria for repeat biopsies and the initiation of curative treatment (experimental arm). Patients are stratified by centre and Gleason score.

Follow-up both groups: PSA every 6 months, clinical examination (with PSA test) annually, and MRI every second year.

Repeat biopsies (reference arm): Current practice

Repeat biopsies (experimental arm), standardised triggers:

1. A systematic repeat biopsy if PSA density increases to \> 0.2 ng/ml/cc, and then at every 0.1 ng/ml/cc increase
2. MRI progression in men with previously only Gleason grade 3+3: 5 mm or more increase in size in any dimension of a measurable lesion, increase in PI-RADS score to 3-5, a new lesion with PI-RADS score 3-5, or high or very high suspicion of extra-capsular extension or seminal vesicle invasion
3. MRI progression in men with Gleason grade 3+4: 5 mm or more increase in size in any dimension of a measurable lesion, or a new lesion with PI-RADS score 3-5

Curative treatment (reference arm): Current practice

Curative treatment (experimental arm), standardised triggers:

1. MRI progression in lesions with confirmed Gleason grade 4: increase in PI-RADS score to 4 or 5, or high or very high suspicion of extra-capsular extension or seminal vesicle invasion
2. Pathological progression: Gleason pattern 5, primary Gleason pattern 4 in any core with 5 mm or more cancer, Gleason 3+4 in 3 or more cores or 30% if more than 10 cores are taken, or Gleason 3+4 in 10 mm or more cancer

Patients will be followed continuously until initiation of treatment, the event of metastasis, to a break point where active surveillance is considered terminated and watchful waiting starts, or to death of any cause. For men who discontinue active surveillance, the follow-up and management continue according to standard clinical practice but with annual reporting in the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Current clinical practice for active surveillance

In this arm, patients are monitored according to current clinical practice for active surveillance at the trial centre. Repeat biopsies (and/or other examinations) and curative treatment are performed according to the urologist's judgement.

Group Type ACTIVE_COMPARATOR

Active surveillance

Intervention Type PROCEDURE

Active monitoring of prostate cancer and curative treatment if there are signs of tumor progression.

Standardized triggers for initiation of treatment with curative intent

In this arm, patients are monitored according to a standardized active surveillance protocol with specific triggers for treatment. Repeat biopsies and curative treatment are only initiated if/when specific criteria are fulfilled.

Group Type EXPERIMENTAL

Active surveillance

Intervention Type PROCEDURE

Active monitoring of prostate cancer and curative treatment if there are signs of tumor progression.
