1.1 Objectives/Aims
Though radiotherapy killing tumor tissues, it may cause necrosis of
surrounding tissues and exposure of the carotid artery, leading to fatal
hemorrhage in certain patients with carotid artery invasion. No relevant
studies have reported the therapeutic effects and associated risk
factors for fatal massive hemorrhage in patients with LANC accompanied
by carotid artery invasion. This retrospective study analyzed the
therapeutic effects and associated risk factors in such patients.
