Toll like receptors as a risk factor for early death in elderly cancer patients.

133Background: the elderly cancer group is a heterogeneous and growing one. In the elderly, the genes of toll-like receptors (TLR) have been described as related to the immunosenescence process and carcinogenesis. The relationship of this gene family with carcinogenesis and immunoregulatory responses seems a promising field. Methods: Between 2015 and 2016, a prospective cohort study in 445 elderly patients with incident cancer ( ≥ 60 years) at the time of admission, assessed and collected sociodemographic and clinical variables and collected analysis of peripheral blood in translational exploratory study. Determination of TLR2 and TLR9 was performed by flow cytometry with monoclonal antibodies anti-TLR2 and TLR9 in the peripheral blood at the beginning of anti-cancer therapy in older patients with cancer. Results: 445 elderly patients were included with incident cancer, age of 71.13 years (SD 7.41) means. Most were male (50.9%) and self-reported black or brown skin color (71.4%). The topography of prostat...
