Abstract/OtherAbstract:
BACKGROUND: Evaluate the production of TNF and IL-6 in the supernatant of peripheral blood mononuclear cell (PBMC) cultures of patients with supraglottic laryngeal cancer before and after surgical treatment. MATERIALS AND METHODS: Adherent cell cultures were stimulated with LPS and BCG. Fourteen patients with advanced supraglottic laryngeal cancer were studied. Cytokine concentration was determined by ELISA in supernatants of mononuclear cell cultures. RESULTS: In non-stimulated cultures, lower TNF cytokine levels were detected during the late postoperative (LP) period compared to control (P = 0.02). LP TNF and IL-6 levels were high in cultures stimulated with LPS compared with the preoperative period (PREOP) (P = 0.007; P = 0.008, respectively). Stimulation with BCG led to increased levels of TNF and IL-6 during the LP period compared to control (P = 0.001; P = 0.04, respectively). CONCLUSION: BCG is able to modulate the immune response of patients with advanced supraglottic laryngeal cancer in vitro, increasing the secretion of TNF and IL-6 by macrophages during the postoperative period.
