High Altitude Carotid Body Tumors Growth During active Surveillance

High Altitude Carotid Body Tumors Growth During active Surveillance BackgroundThe gold standard for patients with carotid body tumors (CBT) is surgical resection; nevertheless, some patients are unfit for surgery or, for other reasons, could not be operated on. Active surveillance has been known to be a reasonable strategy for these cases. This study aimed to evaluate tumor growth in unoperated patients with CBTs.MethodsA retrospective review of all unoperated patients with CBT from a single academic hospital diagnosed between 2014 and 2021 was performed.

Abstract

BackgroundThe gold standard for patients with carotid body tumors (CBT) is surgical resection; nevertheless, some patients are unfit for surgery or, for other reasons, could not be operated on. Active surveillance has been known to be a reasonable strategy for these cases. This study aimed to evaluate tumor growth in unoperated patients with CBTs.MethodsA retrospective review of all unoperated patients with CBT from a single academic hospital diagnosed between 2014 and 2021 was performed. Results of nonparametric testing were presented using the median and ranges for Mann-Whitney-U or Kruskal-Wallis. Significance was defined as a 2-tailed P < .05.ResultsThe cohort included a total of 31 patients, with a median age of 60 years (range: 37-80 years), of which 27 (87.1%) were females. The patients live at a median altitude of 2800 meters (range: 2756-2980 meters) above sea level. Twenty (64.5%) patients had Shamblin I tumors, eight (25.8%) patients had Shamblin II tumors, and three (9.7%) patients had Shamblin III tumors. Median CBT volume at diagnosis was 14.1 cm3 (range: .9 - 213.3 cm3). Median volume at diagnosis of symptomatic tumors was substantially larger than asymptomatic tumors, 49.2 cm3 vs 7.9 cm3, respectively (P = .03). Median growth of the tumors during a median 15-month follow-up (range: 3-43 months) was 3.3 cm3 (range: 0-199.9 cm3).
