Impact of rural location on receipt of standard of care treatment and survival for locally advanced bladder cancer in Louisiana

Abstract Objective We aim to determine the effect of region of residence (urban vs. rural) on the odds of receiving standard of care treatment for locally advanced BCa in Louisiana and its impact on survival outcomes. Methods Using the Louisiana Tumor Registry, we identified American Joint Committee on Cancer (AJCC) stage II or III, BCa diagnoses in Louisiana residents between 2010 and 2020. Treatment received was classified as standard or non‐standard of care according to American Urological Association (AUA) guidelines and location of residence was determined using Rural Urban Commuting Area‐Tract‐level 2010 (RUCA). Multivariable logistic regression analyses and multivariate cox proportional hazard analyses were performed. Results Of 983 eligible patients, 85.6% (841/983) lived in urban areas. Overall, only 37.5% received standard‐of‐care (SOC) for the definitive management of locally advanced bladder cancer. Individuals living in rural areas (OR 0.53, 95% CI: 0.31–0.91, p = 0.02) were less likely to receive standard of care treatment. Both rural residence and receipt of non‐standard of care therapy were associated with an increased risk of bladder cancer‐specific (adj HR 1.53, 95% CI: 1.09–2.14, p = 0.01 and adj HR: 1.85, 95% CI: 1.43–2.39, <0.0001) and overall mortality (adj HR: 1.28, 95% CI: 1.01–1.61, p = 0.04 and adj HR: 1.73 95% CI: 1.44–2.07, p < 0.0001). Conclusions Most patients with locally advanced bladder cancer in Louisiana do not receive SOC therapy. Individuals living in rural locations are more likely to receive non‐standard of care therapy than individuals in urban areas. Nonstandard of care treatment and rural residence are both associated with worse survival outcomes for Louisiana residents with locally advanced bladder cancer.
