Is this trial a fit for you?

Likely a good fit

Adults (18+) with localized, non-metastatic rectal cancer treated with TNT or dMMR/MSI-H disease.

Probably not a fit

Patients whose data are not used for research or who do not consent to participation may not contribute to the findings.

What this trial studies

This observational registry gathers routine-care information from about 600 adults treated at roughly six Austrian sites. It focuses on locally advanced rectal adenocarcinoma, documenting treatment approaches—especially total neoadjuvant therapy—and disease status by microsatellite condition (dMMR/MSI-H). Data come from standard clinical care without altering treatment decisions, and both retrospective and prospective participants are included. The study aims to characterize variability in practice and associated outcomes across institutions. No interventional procedures are required beyond usual care, and participation does not change treatment.

Why it matters

Potential benefit: Gathers real-world insights that may inform future guidelines and help clinicians optimize treatment choices for rectal cancer.

How similar studies have gone: Other observational registries in cancer care have successfully identified practice patterns and outcomes across centers.
