Официальное название
Multicenter Validation of the Stockholm3 Test on Men on Active Surveillance: the CHAS3-Trial
Обзор
The CHAS3 trial studies whether the Stockholm3 blood test can reliably detect if prostate cancer becomes more aggressive in men who are being carefully monitored instead of treated right away (active surveillance). The goal is to see if this test can help doctors safely follow patients with fewer invasive procedures, such as repeated biopsies.
Подробное описание
The CHAS3 trial is a study carried out at several hospitals that follows men with prostate cancer who are being closely monitored through active surveillance. The study looks at how well the Stockholm3 blood test can predict whether the cancer has become more serious when the men later have their scheduled follow-up biopsy.
Men who are already on active surveillance and planned for a routine biopsy may be invited to join. Participants must be alive and must not have started any treatments such as surgery, radiation, hormone therapy, or chemotherapy. To avoid extra procedures, any study samples will be taken at the same time as the patient's regular follow-up visits.
