Monitoring low-risk prostate cancer without immediate treatment

The UCLA ASCAP Project is an Observational, Longitudinal, and Open-ended Study Aimed at Establishing a Structured Program of Non-interventional Follow-up for Localized Prostate Cancer.

Observational Jonsson Comprehensive Cancer Center · NCT00949819

This study looks at how men with low-risk prostate cancer can be monitored over time without immediate treatment to understand how the disease progresses and how to best manage it.

What this trial studies

This observational protocol focuses on men with low-risk, localized prostate cancer, specifically those with Gleason 6 tumors. Participants will be monitored over time to collect clinical data and specimens, assessing factors such as imaging results, rates of curative interventions, tumor progression, and quality of life. Unlike traditional clinical trials, this study does not involve randomization or treatment interventions, but rather aims to gather valuable information on the natural progression of the disease. The goal is to better understand how to manage prostate cancer in patients who choose active surveillance.

Who should consider this trial

Good fit: Ideal candidates are men with histologically confirmed adenocarcinoma of the prostate who have localized disease and have chosen active surveillance as their management plan.

Not a fit: Patients with advanced prostate cancer or those who are unwilling to undergo serial biopsies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved management strategies for low-risk prostate cancer, potentially reducing unnecessary treatments.

How similar studies have performed: Previous studies on active surveillance for low-risk prostate cancer have shown promising results, indicating that this approach is gaining acceptance in clinical practice.
