ABCSG R07 Rectal Cancer Registry (ABCSG R07 RCR)

16. september 2026 opdateret af: Austrian Breast & Colorectal Cancer Study Group

ABCSG R07 Rectal Cancer Registry (RCR) - Multicenter Retrospective and Prospective Analysis of Patients With Localized, Non-metastatic Rectal Cancer in Austria

In Austria, patients with rectal cancer that has not spread to other parts of the body are typically treated with either total neoadjuvant therapy (TNT) or immunotherapy, depending on their microsatellite status (DNA repair capacity).

However, treatment can vary considerably between hospitals in Austria. These differences may include the type and duration of treatment, as well as the active ingredients used. There are currently no clear recommendations on which exact treatment is best for each specific case.

The aim of this observational study is to collect information on the different treatments used in Austria for patients with localized rectal cancer and to document the outcomes of these treatments.

Only information and samples collected as part of the patients' routine care will be used for the study. Participation in the study will not change or affect the treatment chosen by the treating physician.

Detaljeret beskrivelse

The purpose of this observational study is to establish a registry for locally advanced rectal adenocarcinoma. This registry will document the treatment regimens of participants receiving "total neoadjuvant therapy (TNT)" as well as those with dMMR/MSI-H disease.

The ABCSG R07 Rectal Cancer Registry (RCR) study will provide real-world data that reflect the current therapeutic landscape for participants. Participants who are either treated with "total neoadjuvant therapy (TNT)" or those with dMMR/ MSI-H disease, as well as their response to the respective standard therapy, will be documented.

"Total neoadjuvant therapy (TNT)" is the preferred treatment option for locally advanced rectal adenocarcinoma; however, treatment is carried out according to a different TNT protocol at each hospital or institute.

Since the observational study does not interfere with the course of treatment, neither additional health risks nor any individual benefit from participation in the non-interventional study is to be expected.

This study is being conducted at approx. 6 study sites in Austria, and a total of about 600 participants (retrospective and prospective) will take part. The treating physician selects the treatment/therapy that she/he considers most appropriate for the participant. In the retrospective part participants with localized, non-metastatic rectal cancer treated with total neoadjuvant therapy or participants with dMMR/MSI-H status irrespective of treatment between June 2020 (or June 2005 for dMMR/MSI-H cohort,) and start of this non-interventional study will be enrolled.

In the prospective part participants with localized, non-metastatic rectal cancer treated with total neoadjuvant therapy or participants with dMMR/MSI-H status irrespective of treatment between start of this non-interventional study and three years thereafter will be enrolled.
