Patterns of Medical Care Cost by Service Type for Patients With Recurrent and De Novo Advanced Cancer

Abstract Objectives There is limited knowledge about the cost patterns of patients who receive a diagnosis of de novo and recurrent advanced cancers in the United States. Methods Data on patients who received a diagnosis of de novo stage IV or recurrent breast, colorectal, or lung cancer between 2000 and 2012 from 3 integrated health systems were used to estimate average annual costs for total, ambulatory, inpatient, medication, and other services during (1) 12 months preceding de novo or recurrent diagnosis (preindex) and (2) diagnosis month through 11 months after (postindex), from the payer perspective. Generalized linear regression models estimated costs adjusting for patient and clinical factors. Results Patients who developed a recurrence Conclusions Our findings reveal distinct cost patterns between patients with de novo stage IV, recurrent
