Financial toxicity of oral therapies in advanced prostate cancer.

Abstract

The treatment landscape of advanced prostate cancer (CaP) has evolved significantly over the past 20 years. As the number of oral anticancer treatment options continues to increase, so do the costs of these drugs. Furthermore, payment responsibility for these treatments is increasingly shifted from insurers to patients. In this narrative review, we sought to summarize existing assessments of financial toxicity (FT) associated with oral advanced CaP treatments, describe efforts targeted at limiting FT from these agents, and identify areas in need of further investigation. FT is understudied in advanced CaP. Oral treatment options are associated with significantly higher direct costs to patients compared to standard androgen deprivation therapy or chemotherapy. Financial assistance programs, Medicare low-income subsidies, and recent health policy changes help offset these costs for some patients. Physicians are reluctant to discuss treatment costs with patients and further work is needed to better understand best practices for inclusion of FT discussions in shared decision-making. Oral therapies for advanced CaP are associated with significantly higher patient out-of-pocket costs which may contribute to FT. Currently, little is known regarding the extent and severity of these costs on patients' lives. While recent policy changes have helped reduce these costs for some patients, more work is needed to better characterize FT in this population to inform interventions that improve access to care and lessen the harms associated with the cost of novel treatments.
