Urban-rural differences in financial toxicity and its effect on cancer survivors' health-related quality of life and emotional status: a latent class analysis.

Objective: This study aimed to investigate the urban-rural differences in associations between financial toxicity (FT), physical health-related quality of life (HRQoL), negative emotional status, and the effect of patients' socioeconomic status and clinical and cost-related characteristics on the levels of FT in a sample of Chinese cancer survivors.

Methods: Data were obtained from a cross-sectional survey conducted by the oncology department at two tertiary level hospitals in China. The COmprehensive Score for financial Toxicity, Euroqol five-level instrument (EQ-5D), and Depression Anxiety Stress Scale - 21 (DASS-21) were used to measure patients' FT, physical HRQoL, and negative emotional status. A latent class analysis was used to identify patient subgroups with distinct symptom experiences based on self-reported data on symptom occurrence using the EQ-5D and DASS-21.

Results: Four distinct latent classes were identified: all low (47.6%); high physical and low psych (18.6%); low physical and high psych (17.1%); and all high (17.1%). Rural patients younger than 50 years showed a statistically significantly higher FT than urban patients. Rural patients who were male, highly educated, insured, first hospitalization, new cases, received surgery or immunotherapy, and had low cancer-related costs in all low classes showed a higher FT than urban patients.

Conclusions: Rural patients with cancer suffered from higher FT than their urban counterparts, and the negative impact of psychological distress on FT was higher than that of physical HRQoL.
