Observational Study of Active Surveillance for Prostate Cancer

This study, called Active Surveillance for Cancer of the Prostate (ASCaP), is looking at men with prostate cancer who have chosen Active Surveillance as their management plan. Active Surveillance means carefully monitoring the cancer over time, with the option for treatment if the cancer shows significant progression. This study aims to find clinical factors that can predict when prostate cancer might become more aggressive. You could be eligible if you are a man between 30 and 85 years old, have been diagnosed with localized prostate cancer, and have not had previous treatment for it. The study will track information like imaging results, rates of treatment, and how the cancer progresses, with data analyzed yearly. The current status of this study is unclear.
