Role of leukemia inhibitory factor in nasopharyngeal carcinogenesis.

ABSTRACT: Although Epstein-Barr virus-associated nasopharyngeal carcinoma (NPC) is a highly radiosensitive cancer, approximately 20% of patients with NPC develop local recurrence after radiation therapy. Multiple proinflammatory cytokines are thought to protect NPC tumor cells from immune surveillance and therapeutic interventions. The cytokine leukemia inhibitory factor (LIF) is a critical component of the NPC microenvironment. LIF influences tumor growth and survival, and is therefore considered a potential therapeutic target and/or prognostic predictor for NPC. High LIF levels have been detected in the circulating blood of patients with recurrent NPC and NPC tumor cells. This review discusses the molecular mechanisms that link LIF to NPC tumor progression and radioresistance.
