Carotid body tumors in inhabitants of altitudes higher than 2000 meters above sea level

Abstract

We conclude that cases of CBT in our high-altitude population differ significantly from those cases in inhabitants of cities in the U.S. or Europe of less than 1500 m above sea level. Those of high altitudes have an evident female predominance (8.3:1), low rate of bilaterality (5%), and a family history of 1% versus a discrete female predominance (2:1), bilaterality from 10% to 20%, and family history from 7% to 25% in low altitudes. When adequate criteria are used to determine surgical resectability, a complete resection is achieved in 85% of cases, with low or null mortality and high local control.
