Objective: to investigate whether patient demographic characteristics and patients' companions influence variation in patient question asking during cancer clinical interactions, thus representing a potential disparity in access to information.

Methods: data included 109 oncologist-patient-companion interactions video recorded at a comprehensive cancer center. Interactions were observed and analyzed using the Karmanos Information Seeking Analysis System (K-ISAS).
