Hung P, Deng S, Zahnd WE, et al. - Given the persistence of rural-urban differences for colorectal and cervical cancers that raise concerns about access to treatment providers, researchers here sought to determine rural-urban differences in residential proximity to cancer specialists. They used the 2018 Physician Compare data concerning physician practice locations and the 2012 to 2016 American Community Survey to determine the driving distance from each residential zip code tabulation area (ZCTA) centroid to the nearest cancer provider of the following medical specialties committed in managing patients with colorectal and cervical cancer: medical oncology, radiation oncology, surgical oncology, general surgery, gynecological oncology, and colorectal surgery. They used population-weighted multivariable logistic regression, to assess the relationships between ZCTA-level characteristics and driving distances > 60 miles to each type of specialist. Residence > 60 miles from a medical oncologist was reported for nearly 1 in 5 rural Americans. A substantial increase in rural-urban differences in travel distances to the nearest cancer care provider(s) was observed for cancer surgeons; to reach a gynecological oncologist, greater than one-half of rural residents were compelled to travel 60 miles vs 8 miles for their urban counterparts. In view of the substantial travel distances required for rural, low-income residents to reach a cancer specialist, they emphasize policy action expanding access to specialized cancer care for millions of rural residents.
