PURPOSE: This study investigates the relationship between prediagnosis financial hardship (FH) and cancer stage, and the mediating role of cancer screening in breast cancer.
METHODS: This case-control study used linked, deidentified records from adult cancer patients diagnosed with stage I to IV solid tumors (2014-2017) from the Western Washington SEER registry, along with credit report data from TransUnion and health care claims, encompassing various cancers. FH was defined as at least one record of collections, charge-offs, delinquent mortgage payments, tax liens, foreclosures, repossessions, or bankruptcies within 2 years before diagnosis. We used multivariable log-binomial regression to assess the association between FH and late-stage diagnosis (stages III and IV) overall and by cancer screening category, and mediation analysis to evaluate the role of screening mammography in breast cancer.
RESULTS: Among 50,148 patients with cancer (mean age 64 years, 52% female, 85% non-Hispanic White), 30% experienced FH before diagnosis, which was associated with a 14% higher probability of late-stage diagnosis (adjusted risk ratio [aRR], 1.14 [95% CI, 1.11 to 1.17]). This association was stronger for cancers with organized screening (aRR, 1.25 [95% CI, 1.21 to 1.29]) and those detectable by physical examinations (aRR, 1.44 [95% CI, 1.31 to 1.59]), but not for cancers without these protocols (aRR, 1.00 [95% CI, 0.94 to 1.07]), with variations among individual sites. Among patients with breast cancer, 70% of the increased risk of late-stage diagnosis was attributable to the nonreceipt of screening.
CONCLUSION: FH significantly affects cancer stage at diagnosis, especially for cancers with organized screening and physical examinations. In breast cancer, this association is largely attributed to lack of screening. These findings underscore FH as an important social determinant of health and the need for targeted interventions to improve screening access.
