Active Surveillance for Low-risk Prostate Cancer - Evaluation of the Efficacy of Minimally Invasive Active Surveillance (STHLM3AS)
Study Overview

Intervention / Treatment
Detailed Description
The study design is a cross-sectional study, using a paired design, evaluating our proposed protocol (Stockholm3+MRI+targeted biopsies) versus the standard protocol (PSA+systematic biopsies).
Men from the STHLM3 study, diagnosed with low risk prostate cancer and currently on AS will be invited to the study. Eligible individuals have to be alive without any severe comorbidity and without a history of initiating treatment; surgery, radiation, hormone therapy or chemotherapy. To avoid the need for additional biopsies, invitation will be synchronized with timing for planned follow-up within the AS program for each individual.
At baseline blood will be drawn for PSA and Stockholm3 analyses. The patient will be asked to fill out a study specific questionnaire with questions on anxiety and quality of life. Additionally, a bi-parametric MRI evaluated in line with PI-RADS v2 guidelines will be performed. For men with PIRADS ≥ 3 targeted and systematic biopsies will be performed. For men with PIRADS<3 only systematic biopsies will be performed.
Main outcome measurement will be number of detected significant cancers by each method. Further outcome measurements are the number of performed prostate biopsies with each method and level of anxiety and quality of life.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Information obtained in the study will be collected in one database. The purpose of the database is to collect study data in a proper and safe way for a long time. All information about the participants will be treated with utmost confidentiality and with strong safeguards to preserve their anonymity. Information that can be used to identify the participant (such as name, address and social security numbers) is always kept separate from other data (such as survey responses and blood tests). All questionnaire data and test results will be treated to prevent unauthorized access to them. The samples will get a unique code so that outsiders cannot identify them. The participants' samples are treated in accordance with the Swedish Biobank Act.
Everyone who works with STHLM3 are under confidentiality agreements. Results from the study are presented only as statistics in which individual answers cannot be traced.
