Rectal cancer registry to track real-world treatments and outcomes
Official title: ABCSG R07 Rectal Cancer Registry (RCR) - Multicenter Retrospective and Prospective Analysis of Patients With Localized, Non-metastatic Rectal Cancer in Austria
Run by Austrian Breast & Colorectal Cancer Study Group · NCT07780305 · Data updated 2026-11-12
This registry collects real-world data on how locally advanced rectal cancer is treated in Austria, to see how TNT and dMMR/MSI-H cases are managed and what outcomes occur.

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.
