The Biomarkers Why do we need biomarkers ? ü AnMcipate the natural progression or agressivness of the tumor (PronosMc markers) (PredicMve markers) ü Correlate with response during treatment (Surrogate markers) ü AnMcipate the response to treatment or at the Mme-­‐point of tumor assessment ü Predict the immune-­‐related adverse events. ! The Biomarkers Biomarkers can originate from: . The serum, , the urines, the feces, ….. . The immune cell subsets in the peripheral blood . The tumor infiltraMng lymphocytes . The tumor cells and its microenvironment The field is open: -­‐> NONE* has been taken into consideraMon for treatment decisions thus far.

Rational: intratumoral T-cell accumulation and MHC I upregulation Adapted from Johanna Bendell at 2016 ASCO Annual Meeting Immune infiltraMon in biopsies + ycTNM could predict the outcome PaMents with a good/intermediate response to RCT + a high immune infiltraMon will experience a very low rate of relapse Immune status + Imaging 52% pts biopsy rectum Immune investigation RCT Imaging CD3 + ycTNM Conclusion Change of paradigm . The immune system is now recognized as a major player in the control of the tumor process . Immunotherapy has now gain a forefront posiMon in cancer treatment . There is a need for biomarkers to predict the outcome and influence treatment decisions .
