Screening Trials
Research studies that aim to evaluate new tests for detecting cancer and other health conditions before symptoms appear. The goal is to determine if such tests can save lives and at what cost.
Assessing the effectiveness of early detection
Screening trials in the United States assess the effectiveness of screening methods for the early detection of diseases or conditions in individuals who may not yet show symptoms. The goal is to identify cases at an earlier, more treatable stage.
The three types of screening trials
Early Detection Trials: These trials focus on finding cancer or other diseases at an early stage when treatment is more likely to be successful.
Diagnostic Trials: These trials evaluate new tests to diagnose a specific disease or condition more accurately or efficiently.
Prognostic Trials: These trials assess new tests to predict the course of a disease or the likelihood of developing a disease.
How screening trials work
Eligibility Screening: Potential participants are screened to determine if they meet the eligibility criteria for the trial. This may involve reviewing medical records, conducting physical exams, and performing laboratory tests.
Informed Consent: Once eligible, participants must provide informed consent, meaning they understand the risks and benefits of participating in the trial.
Screening Test: Participants undergo the new screening test being studied.
Follow-up: Participants are followed over time to monitor their health status and to determine the effectiveness of the screening test.
Considerations
Your doctor can also help you find screening trials that may be relevant to your health needs. It's important to weigh the potential risks and benefits of participating in a screening trial. Make sure you fully understand the trial before agreeing to participate. Some trials may have associated costs, such as travel or medical tests. Participation in a screening trial may require regular visits and follow-up appointments.
