Longitudinal studies on financial toxicity in cancer patients: a scoping review

The measurement time points of financial toxicity in cancer patients are mostly concentrated within one year after treatment, with insufficient research on long-term follow-up. The existing assessment tools lack applicability for long-term tracking and specificity for different cancer types, and objective indicators fail to effectively reflect patients' economic status due to disparities in regional economic development levels. Patients with different types of cancer exhibit distinct developmental trends of financial toxicity, indicating population heterogeneity. Future research still needs to further explore the influencing factors and developmental trajectories of financial toxicity among different cancer types.
