Patients with early-stage bladder cancer who live in more economically disadvantaged neighborhoods face a higher risk of dying from their cancer, even when the disease has not spread beyond the bladder, according to a study published recently in BJUI International.
Researchers found that increasing levels of neighborhood deprivation were linked to steadily higher cancer-specific mortality, suggesting that social and economic conditions play a meaningful role in long-term outcomes for people with non-muscle-invasive bladder cancer.
The analysis reviewed records from 19,722 patients in Michigan diagnosed with non-muscle-invasive bladder cancer between 2004 and 2019. All patients had tumors confined to the bladder lining or connective tissue, with no lymph node involvement or distant spread.
Researchers measured neighborhood disadvantage using the Area Deprivation Index (ADI), which ranks communities nationwide based on factors such as income, education, employment and housing quality. Patients were grouped into four quartiles, from least deprived to most deprived.

Most patients were older adults, with a median age of 72 years, and about three-quarters were men. The majority were non-Hispanic white, lived in metropolitan areas and were married. Nearly one-third of patients lived in the most deprived neighborhoods, defined as ADI scores in the 75 to 100 percentile range.
Over 10 years of follow-up, deaths specifically due to bladder cancer increased as neighborhood deprivation rose. Cancer-specific mortality was 7.3% in the least deprived group and climbed to 9.7% in the most deprived group. The differences were statistically significant. When researchers adjusted for other factors, each 25-point increase in ADI was linked to a 6% higher risk of dying from bladder cancer.
The study’s authors noted that bladder cancer care usually means years of follow-up appointments and careful monitoring. “A care pathway with this many touchpoints is precisely where socioeconomic factors can exert cumulative effects on timeliness, adherence, and treatment intensity,” said the authors. “For many patients in high-deprivation settings, the opportunity cost of care — lost wages, inflexible work schedules, and competing caregiving demands — can lead to missed surveillance visits or delayed evaluations.”
Other characteristics also mattered. Older age, more advanced tumor stage within early disease, being unmarried and having Medicaid insurance were all independently associated with higher cancer-specific mortality. These results suggest that both medical and social factors influence survival.
For patients, the results highlight that outcomes are shaped by more than tumor biology alone. Living in an area with fewer resources may affect access to regular follow-up, timely treatment, transportation, health literacy or support systems. The study suggests that clinicians may need to consider a patient’s socioeconomic context when planning surveillance and care, with the goal of reducing disparities and improving survival for people with early-stage bladder cancer.
