Follow-Up Intervals for Colon Polyps
(STARLING Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine whether a follow-up colonoscopy 6 months or 12 months after removing a large colon polyp is more effective at detecting regrowth. It focuses on polyps measuring 20-50mm that do not exhibit severe abnormal cell growth (high-grade dysplasia). Individuals who have had a large non-pedunculated polyp removed during a colonoscopy and can complete a simple electronic survey are suitable candidates for this study. As an unphased trial, it offers participants the chance to contribute to important research that could enhance follow-up care for others.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these follow-up intervals are safe?
Research has shown that a check-up 12 months after removing a large polyp is generally safe for most people. However, a small chance exists that waiting a year could delay the detection of new problems, though this is uncommon.
A 6-month check-up is also a common practice for monitoring large polyps. This shorter interval can help identify new growths sooner, providing reassurance.
Both the 6-month and 12-month follow-up times are standard and safe for patients. The choice between them may depend on individual health needs and a doctor's recommendation.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it aims to find out the best follow-up interval after removing large colon polyps. Unlike the standard practice of recommending follow-ups based on general guidelines, this trial specifically compares 6-month and 12-month intervals. By determining if one interval is more effective at detecting regrowth earlier, the trial could lead to more personalized and timely care, potentially catching issues sooner and improving patient outcomes. This could refine current practices and provide clearer guidelines for patients and doctors.
What evidence suggests that this trial's follow-up intervals could be effective for colon polyps?
This trial will compare two follow-up intervals for patients after large polyp removal: a 12-month follow-up and a 6-month follow-up. Studies have shown that the timing of check-ups after polyp removal can influence how soon new polyps are detected. A 12-month follow-up often monitors patients after large polyps are removed, especially when there's no immediate cancer concern. However, some experts believe that waiting 12 months might delay early detection of new issues. Alternatively, a 6-month follow-up is sometimes recommended for larger polyps, as it can help detect regrowth sooner. This shorter interval aligns with some guidelines suggesting early checks for large polyps. Both options have their pros and cons, and the decision typically depends on personal risk factors and medical advice.13567

Are You a Good Fit for This Trial?
This trial is for individuals who have had a large non-pedunculated colon polyp (20-50mm) removed, which did not show high-grade dysplasia. Specific eligibility criteria are not provided, but typically participants should meet certain health standards and may be excluded based on factors that could impact the study's results.Inclusion Criteria

Trial Overview
The study aims to determine whether a follow-up at 6 months is as effective as a follow-up at 12 months after the removal of large colon polyps. It compares two groups: one receiving an earlier checkup and another with a later checkup to monitor for any signs of polyp recurrence or complications.

Experimental Treatment
Patients will be recommended to complete their first surveillance procedure 6 months after the large polyp removal procedure in order to assess whether the polyp grew back.
Patients will be recommended to complete their first surveillance procedure 12 months after the large polyp removal procedure in order to assess whether the polyp grew back.
