This analysis included patients who were diagnosed 4 to 120 months after their AIDS diagnosis.
Hepatobiliary cancers were classified according to the International Classification of Diseases for Oncology (ICD-O3; 3rd edition) topography and morphology codes described elsewhere (for a detailed listing of the cancers included in these categories, please refer to the article by Altekruse SF, Devesa SS, Dickie LA, McGlynn KA, Kleiner DE. Histological classification of liver and intrahepatic bile duct cancers in SEER registries. J Registry Manag. 2011;38:201–205.14).
