Methods
With Institutional Review Board approval from Children’s Healthcare of
Atlanta, the electronic anatomic pathology database was queried for
cases of PTGC that were diagnosed between January 1, 2000 through
December 31, 2020. Data included age and sex at diagnosis as well as
location of involved lymph nodes. Blood test results, radiologic
imaging, and duration of follow-up evaluation were extracted from the
electronic medical record (EMR). Microsoft Excel (v16.62, 2022) was used
for database management, and GraphPad Prism (v9.3.1, 2022) was used for
statistical analyses.
