Objective: To update and integrate existing prostate cancer (PCa) Core Outcome Set (COS) for the different stages of PCa, while also assessing their applicability and developing standardised definitions of prioritised outcomes.
Evidence acquisition: We followed a four-stage process:(1) systematic reviews;(2)
qualitative interviews;(3) expert group meetings to agree standardised terminologies;(4) recommendations for most appropriate definitions of clinician reported outcomes.
Evidence synthesis: Following four systematic reviews, a multinational interview study and expert group consensus meetings, we defined the most clinically suitable definitions for a) localised and locally advanced, and b) metastatic and non-metastatic castration resistant PCa COS. No new outcomes were identified in our COS for localised/locally advanced PCa. For our metastatic and non-metastatic CRPC COS, nine new core outcomes were identified.
Conclusion: These are the first COS in PCa where the definitions of the prioritised outcomes have been surveyed in a systematic, transparent, and replicable way. Furthermore, this is the first-time recommendations for outcome definitions across all prostate cancer COS have been agreed on by a muldisciplinary expert group and recommended for use in research and clinical
practice settings (see Table 4,5). To limit heterogeneity across research, they should be recommended for future effectiveness trials, systematic reviews, guidelines and clinical practice of localised and metastatic PCa.
Patient summary: PCa patient outcomes after treatment are difficult to compare due to variability. To enable better use of PCa patient data, PIONEER standardised and recommended outcomes (and their definitions) that should be collected as a minimum in all future studies.
