AGMT Metastatic Colorectal Cancer Registry (mCRC) Third Line and Beyond

Brief Summary

Detailed Description

This registry aims at retrospectively and prospectively evaluating the treatment landscape and clinical outcome of mCRC ≥3L in a collective attempt by including multiple oncologic centers in Austria. Patient medical, testing and treatment information will be obtained through extraction of data from existing patient medical charts. Longitudinal follow-up data, including survival and tumor progression, will also be extracted from patient medical charts. Imaging studies ≥3L will be centrally collected in a virtual "imaging-bank" and tumor tissue samples of deceased patients will be stored in a central "bio-bank". Additionally, further biomaterial (e.g. ctDNA samples or DNA from DPYD genotyping) may be requested from the centres in case of specific research questions. The patient follow-up data will be obtained until patient death or loss to follow-up. For documentation in the registry, no further diagnostic or therapeutic measures are required than those already necessary in general. Participation in the registry must not interfere with treatment routines. Only routine data, which have already been recorded in the patients' medical charts, is transferred to the electronic Case Report Forms. To maintain patient confidentiality, each patient will be assigned a unique patient identifying number upon enrollment; this number will accompany the patients' medical and other registry information throughout the lifetime of the registry. A written consent must be obtained prior to the input of data. No informed consent is required from deceased patients. Data will be collected from all sites willing to participate.
