Diagnostic and Outcome Differences between Sporadic and Familial Cases of Pheochromocytoma and Paraganglioma: A Retrospective Cohort Study Abstract #865

Introduction: Hereditary Pheochromocytomas (PCC) and Paragangliomas (PGL) account for 30-35% of cases and have some clinically relevant peculiarities.
Aim(s): To analyze differences in diagnosis and outcome between sporadic and familial cases of PCC/PGL.
Materials and methods: All genotyped patients (n=31, 24 with PCC and seven with PGL) diagnosed at Hospital Clínico San Carlos between 1988-2012 were included; 35.5% were germline mutation carriers (27.3% pseudohypoxic phenotype [PH], 72.7% MAP-kinase phenotype [MAPK]). Median follow-up was 55 months (IQR 23-91) for 28 patients. A comparative analysis was performed using Mann-Whitney U test, chi-squared test and Breslow test.
