Assessing Knowledge Sharing in Cancer Screening Among High-, Middle-, and Low-Income Countries: Insights From the International Cancer Screening Network

As the global burden of cancer rises, global knowledge sharing of effective cancer control practices will be critical. The International Cancer Screening Network (ICSN) of the US National Cancer Institute facilitates knowledge sharing to advance cancer screening research and practice. Our analysis assessed perceptions of ICSN's value and knowledge sharing in cancer screening among participants working in high-income countries (HICs) and low- and middle-income countries (LMICs). In 2018, the National Cancer Institute fielded a self-administered, online survey to 665 ICSN participants from both HICs and LMICs. Two hundred forty-three individuals (36.5%) completed the full survey. LMIC participants engaged in more diverse screening activities and had fewer years of experience (13.5% with more than 20 years of experience 31%; = .048) in screening and were more interested in cervical cancer (76.9% 52.6%; = .002) than HIC participants. However, both groups spent most of their time on research (30.8% LMIC 36.6% HIC; = .518) and agreed that the ICSN biennial meeting enabled them to learn from the experiences of both higher-resource (88.2% 75.7%; = .122) and lower-resource (61.8% 68.0%; = .507) settings. ICSN helped them form new collaborations for research and implementation (55.1% 58.2%; = .063); informed advances in research/evaluation (71.4% 68.0%; = .695), implementation (59.2% 47.9%; = .259), and policies in their settings (55.1% 48.0%; = .425); and provided the opportunity to contribute their knowledge and expertise to assist others (67.3% 71.1%; = .695). Findings suggest that HIC and LMIC participants benefit from knowledge sharing at ICSN meetings although their interests, backgrounds, and needs differ. This points to the importance of international research networks that are inclusive of HIC and LMIC participants in cancer control to advance knowledge and effective practices globally.
