Data from Sociodemographic Disparities in HER2+ Breast Cancer Trastuzumab Receipt: An English Population-Based Study

Le résumé fourni par la source

AbstractBackground: Sociodemographic disparities in traditional breast cancer treatment receipt in nonpublicly funded healthcare systems are well documented. This study investigated trastuzumab receipt by sociodemographic factors within a female, HER2+ breast cancer population in England’s publicly funded National Health Service. Methods: The English national population-based cancer registry and linked Systemic Anti-Cancer Therapy database identified 36,985 women with HER2+ invasive breast cancer diagnosed between January 1, 2012 and December 31, 2017. Multivariable logistic regression determined the likelihood of trastuzumab receipt in early and metastatic disease by the deprivation category of area of residence and other sociodemographic characteristics. Results: Early-stage trastuzumab receipt followed a socioeconomic gradient. Women residing in the most deprived areas were 10% less likely to receive trastuzumab [multivariable OR 0.90; 95% confidence interval (CI), 0.83–0.98] compared with women residing in the least deprived areas. In both early and metastatic disease, trastuzumab receipt was less likely in older women with more comorbidities, estrogen receptor–positive disease, and who were not discussed at a multidisciplinary team meeting. Conclusions: Despite the provision of free care at the point of delivery in England, sociodemographic disparities in early-stage HER2+ trastuzumab receipt occur. Further research determining how inequities contribute to disparities in outcomes is warranted to ensure optimized trastuzumab use for all. Impact: Fair access to novel cancer treatments regardless of place of residence, sociodemographic characteristics, and/or cancer stage requires prioritization in future cancer improvement policies.
