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.

Who should consider this trial

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.

Not a fit: Patients with evidence of distant metastases will not benefit from this study.

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

Eligibility criteria

Inclusion Criteria:

* Patients with confirmed histopathological diagnosis of rectal adenocarcinoma.

Exclusion Criteria:
