Consensus meeting results
Inclusion | Exclusion | Pre-op biopsy strategy | Biopsy end point | PSA | MRI | Treatment failure | Re-treatment | |
---|---|---|---|---|---|---|---|---|
Van den Bos et al. [61] Multi-stage Delphi process |
3 + 3 with “substantial cancer” 3 + 4 >10-year life expectancy PSA > 15 with caution |
Clinically insignificant disease (volume < 0.5 cc) | MRI targeted or fusion with systematic | Negative 12-month biopsies Targeted and systematic |
3 monthly but not sufficient as an end point | Alterations in MRI not sufficient as end point | Any cancer in-field of treatment Low-grade, low-volume (Gleason 6, <3 mm) out of field is not considered failure |
Acceptable on one occasion |
Donaldson et al. [59] RAND/UCLA appropriateness methodology |
NCCN intermediate risk disease 3 + 3 with >3–5 mm MCCL >10-year life expectancy Multifocal disease included (secondary lesion of Gleason 6, ≤5 mm can be left untreated) |
<5-year life expectancy and those <40 and >80 years with caution WHO performance status 3–4 |
MRI targeted or template mapping (if no MRI available) | 12-month biopsy Targeted only Uncertainty about systematic sampling |
Rising PSA may trigger biopsy | Suspicious MRI may trigger biopsy | Cancer in field of equivalent or higher than pre-operative grade Low-grade, low-volume (Gleason 6, <3 mm) in field is not considered failure |
≤20 % retreatment rates |
Muller et al. [60] Delphi process |
12 month biopsy Targeted and systematic |
3 monthly No consensus on role of PSA |
1st MRI 6 months post-treatment Suspicious MRI should lead to biopsy Further biopsies after 12 months only if suspicious MRI |
