Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with stage II and III rectal adenocarcinoma who have shown a complete or near complete response to neoadjuvant treatment.

Probably not a fit

Patients with evidence of distant metastases will not benefit from this study.

What this trial studies

The PRONAR trial evaluates the feasibility and safety of an organ preservation strategy for patients with locally advanced rectal cancer who show a complete or nearly complete response to neoadjuvant treatment. Patients will undergo MRI and endoscopy to assess their response, with those meeting criteria offered a 'watch and wait' strategy or transanal endoscopic microsurgery. The study aims to analyze survival rates, local and distant relapse, and quality of life outcomes. A total of 30 patients will be recruited over a period of time to assess these outcomes.

Why it matters

Potential benefit: If successful, this approach could reduce the need for radical surgery in patients with locally advanced rectal cancer, potentially improving their quality of life.

How similar studies have gone: Previous studies have shown promising results with organ preservation strategies in rectal cancer, indicating potential for success in this approach.
