Lung Cancer Screening in the National Cancer Institute Community Oncology Research Program: Availability and Service Organization

Abstract

Purpose: Annual low-dose CT (LDCT) for lung screening in high-risk individuals decreases both lung cancer-specific mortality and all-cause mortality. Community oncology practice networks constituting the National Cancer Institute Community Oncology Research Program (NCORP) conduct clinical trials across the cancer spectrum. The authors report access to and characteristics of LDCT screening for lung cancer in these community oncology practices.

Methods: A landscape capacity assessment was conducted in 2017 across the NCORP network. The primary outcome was the proportion of adult oncology practice groups offering LDCT lung screening on site. The secondary outcomes were the proportion of those screening services (1) with radiologist participation in service management and (2) offered at ACR Designated Lung Cancer Screening Centers.

Results: Fifty-two percent of components and subcomponents responded to at least some portion of the assessment, representing 217 practice groups. Analyzing the 211 adult oncology practice groups responding to the primary question, 73% offered lung screening services on site. Radiologists participated in managing 69% of these services. Forty-seven percent were offered in ACR Designated Lung Cancer Screening Centers. Minority and underserved practice groups were less likely to offer lung screening; however, this association dissipated when analyses focused on practices within the United States. Safety net and Critical Access Hospital designation increased the likelihood of screening availability.

Conclusions: The majority of community oncology practice groups within the NCORP offered lung screening on site, although radiologist participation in service management and ACR Lung Cancer Screening Center designation, markers of service quality, were more variable.
