摘 要♥️：
In comparative effectiveness research and precision medicine for rare types of cancer, it is desirable to combine multiple sources of data, e.g., the primary cohort data containing detailed tumor profiles together with aggregate information derived from cancer registry databases. Such integration of data may improve statistical efficiency in estimation and precision in prediction, but also pose statistical challenges for incomparability between different sources of data. We develop the adaptive estimation procedures, which used the combined information to determine the degree of information borrowing from the aggregate data of the external resource or individual-level data source. We apply the proposed method to evaluate the long-term effect of several commonly used treatments for inflammatory breast cancer by tumor subtypes, while combining the inflammatory breast cancer patient cohort at MD Anderson Cancer Center and external cancer registry data.
