Background: Financial hardship is common among cancer survivors and is associated with both limiting care due to cost and with poor health-related quality of life (HRQOL). This study estimates the association between limiting care due to cost and HRQOL in a diverse population of cancer survivors and tests whether limiting care mediates the association between financial hardship and HRQOL., Methods: We used data from 988 participants (579 African American, 409 white) in the Detroit Research on Cancer Survivors (ROCS) pilot, a hospital-based cohort of breast, colorectal, lung, and prostate cancer survivors. We assessed associations between financial hardship, limiting care, and HRQOL [measured by the Functional Assessment of Cancer Therapy-General (FACT-G)] using linear regression and mediation analysis controlling for demographic, socioeconomic, and cancer-related variables., Results: FACT-G scores were 4.2 [95% confidence interval (CI), 2.0-6.4] points lower among survivors who reported financial hardship compared with those who did not in adjusted models. Limiting care due to cost was associated with a -7.8 (95% CI, -5.1 to -10.5) point difference in FACT-G scores. Limiting care due to cost explained 40.5% (95% CI, 25.5%-92.7%) of the association between financial hardship and HRQOL overall, and 50.5% (95% CI, 29.1%-188.1%) of the association for African American survivors., Conclusions: Financial hardship and limiting care due to cost are both associated with lower HRQOL among diverse cancer survivors, and this association is partially explained by limiting care due to cost., Impact: Actions to ensure patients with cancer can access appropriate care could lessen the impact of financial hardship on HRQOL., (©2019 American Association for Cancer Research.)

Background: African Americans are often diagnosed with advanced stage cancer and experience higher mortality compared with whites in the United States. Contributing factors, like differences in access to medical care and the prevalence of comorbidities, do not entirely explain racial differences in outcomes., Methods: The Detroit Research on Cancer Survivors (ROCS) pilot study was conducted to investigate factors related to short- and long-term outcomes among patients with cancer. Participants completed web-based surveys, and mailed saliva specimens were collected for future genetic studies., Results: We recruited 1,000 participants with an overall response rate of 68%. Thirty-one percent completed the survey without any interviewer support and the remaining participated in an interviewer-administered survey. Seventy-four percent provided a saliva specimen and 64% consented for tumor tissue retrieval. African American survivors required more interviewer support ( P < 0.001); however, their response rate (69.6%) was higher than non-Hispanic whites (65.4%). African Americans reported poorer overall cancer-related quality of life compared with non-Hispanic whites, measured by FACT-G score ( P < 0.001), however, this relationship was reversed after controlling for socioeconomic factors, marital status, and the presence of comorbidities., Conclusions: In this pilot study, we demonstrated that a web-based survey supplemented with telephone interviews and mailed saliva kits are cost-effective methods to collect patient-reported data and DNA for large studies of cancer survivors with a high proportion of minority patients. The preliminary data collected reinforces differences by race in factors affecting cancer outcomes. Our efforts continue as we expand this unique cohort to include more than 5,000 African American cancer survivors., Impact: Formal investigation of factors influencing adverse outcomes among African American cancer survivors will be critical in closing the racial gap in morbidity and mortality., (©2018 American Association for Cancer Research.)
