Abstract
Background: The incidence and prognosis of colorectal cancer are associated with lifestyle, family history, and genetic predisposition. Record linkage between cancer registries and biospecimen data would enable us to conduct clinical epidemiological studies on incidence or prognosis including genome information. In this study, we conducted a systematic review of clinical epidemiological studies of colorectal cancer using record linkage between cancer registries and biospecimen data and examined the possibilities for future use of this linkage. Methods: We searched PubMed and Google Scholar for articles regarding cancer registries and biospecimen data use published before December 2021. Selected articles were summarized by cancer registry use, biospecimen use, exposure, outcome, informed consent, and participant numbers by study design and type of cancer registry. Results: Of the 2,793 identified articles, 81 studies were included in this review. The most frequently used cancer registries and study design were site specific cancer registries and cohort studies. Most use of cancer registries was for patient selection in cohort studies and case selection in case-control studies. Most use of biospecimen data was for prognostic factors in cohort studies and risk factors in case-control studies. In site specific cancer registries for the examination of familial colorectal cancer, most use of biospecimen data is to examine genome mutation, expression, or deficiency. Conclusion: We suggest that record linkage between cancer registries and biospecimen data would enable the accurate capture of outcomes and detailed genome-environmental factors, and to conduct clinical epidemiological studies according to specific research questions and tailored study designs.
