Brief Summary

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

The clinical objective for this pilot study is to determine whether minimal residual disease (MRD) detection in high-risk prostate cancer, utilizing a custom-made prostate-specific circulating tumor DNA (ctDNA) panel, may lead to more optimal prediction of disease recurrence following radical prostatectomy.

Study Groups

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

High-risk localized prostate cancer or high-risk locally advanced prostate cancer

Included patients will have:

1. High-risk localized prostate cancer, with PSA level \>20 ng/mL, Gleason score 8-10 (ISUP grade 4/5) at prostate biopsies, or iT3a (based on multi-parametric MRI of the prostate); or
2. High-risk locally advanced prostate cancer, having any PSA level, any Gleason score/ISUP grade, iT3b-4 (based on multi-parametric MRI of the prostate) or iN1 (based on PSMA PET/CT imaging).

No interventions assigned to this group

Eligibility Criteria
