Introduction to Financial Toxicity and the Growing Affordability Crisis

Impact of Financial Toxicity on Treatment Adherence and Quality of Life in Pancreatic Cancer

PURPOSE

Financial toxicity (FT) is increasingly recognized as a major issue in cancer care. We evaluated the prevalence and risk factors for FT in patients with pancreatic ductal adenocarcinoma (PDAC) and FT associations with treatment adherence and quality of life (QOL).

METHODS

A screening questionnaire based on the Comprehensive Score for Financial Toxicity (COST) was implemented at our National Cancer Institute-designated comprehensive cancer center. Respondents with pathologic diagnosis of PDAC who completed >50% of prompts between June 2022 and June 2023 were analyzed. COST ≤16 was categorized as FT. Associations between FT and demographic and clinical factors were assessed using logistic regression, and QOL was assessed using linear regression.

RESULTS

Of the 1,888 patients with PDAC, 1,162 completed the COST questionnaire, and 1,079 met the inclusion criteria. The prevalence of FT was 23% (n = 245); 37% of patients with FT reported medication nonadherence due to cost. Demographic factors and poor performance status were associated with FT. Treatment-naïve patients were more likely to report FT compared with those on induction, adjuvant, or palliative therapy (P = .049). Patients experiencing FT reported worse QOL, with a median score of 5 (IQR, 4-7) versus 8 (IQR, 6-9) without FT. This relationship persisted after adjusting for demographic and clinical factors; the effect size of FT (β = -1.5; 95% CI, -1.1 to -1.9) was nearly double that of poor performance status (β = -.8; 95% CI, -1.3 to -0.4).

CONCLUSION

FT affected nearly one in four patients with PDAC at a high-volume cancer center and was associated with worse QOL and medication nonadherence. Universal screening and interventions to reduce FT are warranted. Clinical trials investigating QOL as an end point must account for potential confounding due to FT.

Understanding Health-Related Social Risks

Because of the established contribution of social factors to health outcomes, approaches that address upstream determinants of health have increasingly been recognized as cost-effective means to improve population health. Understanding and usage of precise terminology is important to facilitate collaboration across disciplines. Social determinants of health affect everyone, not just the socially and economically disadvantaged, whereas health-related social risks (HRSR) are specific adverse conditions at the individual or family level that are associated with poor health and related to the immediate challenges individuals face. Health-related social needs account for patient preference in addressing identified social risks. The use of validated screening tools is important to capture risk factors in a standardized fashion to support research and quality improvement. There is a paucity of studies that address HRSR in the context of radiology. This review provides an understanding of HRSR and outlines various ways in which radiologists can work to mitigate them.

Incidence and imaging characteristics of difficult to detect retrospectively identified brain metastases in patients receiving repeat courses of stereotactic radiosurgery

PURPOSE

During stereotactic radiosurgery (SRS) planning for brain metastases (BM), brain MRIs are reviewed to select appropriate targets based on radiographic characteristics. Some BM are difficult to detect and/or definitively identify and may go untreated initially, only to become apparent on future imaging. We hypothesized that in patients receiving multiple courses of SRS, reviewing the initial planning MRI would reveal early evidence of lesions that developed into metastases requiring SRS.

METHODS

Patients undergoing two or more courses of SRS to BM within 6 months between 2016 and 2018 were included in this single-institution, retrospective study. Brain MRIs from the initial course were reviewed for lesions at the same location as subsequently treated metastases; if present, this lesion was classified as a "retrospectively identified metastasis" or RIM. RIMs were subcategorized as meeting or not meeting diagnostic imaging criteria for BM (+ DC or -DC, respectively).

RESULTS

Among 683 patients undergoing 923 SRS courses, 98 patients met inclusion criteria. There were 115 repeat courses of SRS, with 345 treated metastases in the subsequent course, 128 of which were associated with RIMs found in a prior MRI. 58% of RIMs were + DC. 17 (15%) of subsequent courses consisted solely of metastases associated with + DC RIMs.

CONCLUSION

Radiographic evidence of brain metastases requiring future treatment was occasionally present on brain MRIs from prior SRS treatments. Most RIMs were + DC, and some subsequent SRS courses treated only + DC RIMs. These findings suggest enhanced BM detection might enable earlier treatment and reduce the need for additional SRS.
