Treatment patterns and outcomes for patients with adrenocortical carcinoma associated with hospital case volume in the United States
Background Adrenocortical carcinoma (ACC) is a rare, aggressive disease with no apparent
change in treatment or survival in the United States over the past two decades. Our objective
was to determine whether treatment patterns or clinical outcomes vary by hospital case
volume. Methods Patients with ACC were identified from the National Cancer Database
(1998–2011). High-volume centers (HVCs) were defined by a case load of≥ 4 cases of
primary adrenal malignancy annually, which corresponded to the 90th percentile. All other …

We read with interest the article by Gratian et al. entitled 'Treatment Patterns and Outcomes
for Patients with Adrenocortical Carcinoma Associated with Hospital Case Volume in the
United States', published in Annals of Surgical Oncology. 1 This study analyzed data from
the National Cancer Data Base (NCDB) Participant Use File (PUF) 2 and is an important
contribution to the literature for this rare cancer. However, we would like to clarify some
statements made in the paper in regard to missing data. The NCDB adds new registry data …
