Brief summary
The proposed study is a bidirectional analytical study, composed of a retrospective and a prospective cohorts. Patients with stage II - III colorectal cancer undergoing oncological surgery will be analyzed. The study will include a convenience sample of 100 individuals. Fifty cases will be included retrospectively and fifty prospectively. The study aims to evaluate the benefit of using the Immunoscore test as a predictor of recurrence in patients with operated stage II-III colon tumors. It will also be evaluated the impact on oncologic decision and costs.
Interventions
Immunoscore® is a tissue-based immune test that measures the host's immune response at the site of the tumor. It is performed on formalin-fixed paraffin-embedded (FFPE) tumor tissue samples from resections of localized colon cancer. The test uses whole slide imaging and artificial intelligence algorithms for assessment of the type, density, and location of T cells in FFPE tumor sections to determine an individual Immunoscore® for each patient.
