Characterisation of patients diagnosed with metastatic head and neck paraganglioma treated at an oncology referral institution in Colombia

#4311

Introduction: Head and neck paragangliomas (HNPGL) are rare tumours. Multiple risk factors associated with the risk of metastasis have been described, although much of the available information corresponds to the group of Pheochromocytoma and Paragangliomas, not necessarily extrapolatable to metastatic HNPGLs.

Aim(s): To describe the demographic, clinical and histological characteristics of patients and estimate overall 5-year survival.

Materials and methods: Retrospective case series of patients treated at the INC between January 1, 2008, and December 31, 2018. A registry of demographic information, tumour characteristics, pathology reports, and treatment variables was performed. A descriptive univariate analysis was performed, and the Kaplan-Meier method was used to determine the 5-year overall survival of all patients.
