A Retrospective Protocol Empowering Precision Research in Colorectal Cancer (ALFAOMEGA-RETRÒ)
ALFAOMEGA-RETRÒ will be exploited to retrospectively collect clinical and imaging data and archival samples to be used for validation and correlative studies on markers discovered by cutting-edge translational projects within the AIRC5x1000 program "Insights into the evolving heterogeneity of colorectal cancer (CRC): from mechanism to therapies" (an ongoing multi-institutional research program).
Inclusion: Histologically-confirmed diagnosis of colorectal cancer (any stage); Age >18 years at the time of diagnosis; Availability of clinically-annotated radio-imaging data and/or diagnostic Formalin-Fixed Paraffin Embedded (FFPE) blocks (surgical resections and/or tumor biopsies), or at least 10 slides (preferably 20). FFPE tissue blocks are always preferred to slides; Verification that the patient could not be reached for informed consent in accordance with applicable national regulations.
Exclusion: if inclusion criteria are not met.
