RT Journal Article T1 Immune Microenvironment in Colorectal Cancer: A New Hallmark to Change Old Paradigms A1 Cruz-Merino, Luis de la A1 Henao Carrasco, Fernando A1 Vicente Baz, David A1 Nogales Fernández, Esteban A1 Reina Zoilo, Juan José A1 Codes Manuel de Villena, Manuel A1 Grande Pulido, Enrique K1 Antígenos CD80 K1 Antineoplásicos K1 Antígeno CTLA-4 K1 Neoplasias Colorrectales K1 Pronóstico K1 Linfocitos T Reguladores AB Impact of immune microenvironment in prognosis of solid tumors has been extensively studied in the last few years. Specifically in colorectal carcinoma, increased knowledge of the immune events around these tumors and their relation with clinical outcomes have led to consider immune microenvironment as one of the most important prognostic factors in this disease. In this review we will summarize and update the current knowledge with respect to this intriguing and complex new hallmark of cancer, paying special attention to infiltration by T-infiltrating lymphocytes and their subtypes in colorectal cancer, as well as its eventual clinical translation in terms of long-term prognosis. Finally, we suggest some possible investigational approaches based on combinatorial strategies to trigger and boost immune reaction against tumor cells.
