IGF::OT::IGF EVALUATING FEASIBILITY OF AND POTENTIAL BIASES IN SUPPLEMENTING CANCER REGISTRY DATA USING EXTERNAL SOURCES(SEER) PERIOD OF PERFORMANCE: 09/18/2015 - 09/17/2016

本研究将告知癌症登记社区何时适合使用外部来源补充癌症登记数据，以及哪些数据项适合在所得统计数据中无偏倚地补充。 将评价误分类偏倚，以检查SEER统计的稳健性。 目的： 第一章 评价使用3个确定来源的数据补充特定选定癌症登记变量（人种-种族、出生地、治疗、肿瘤生物标志物）的可行性：a）患者访谈研究，B）POC和c）电子健康记录（HER）数据。 （二） 评估改进基于SEER的标准癌症报告统计数据的潜力（例如，发病率、患病率、治疗特异性生存率）。

This study will inform the cancer registry community of when it is appropriate to supplement cancer registry data with external sources, and what data items are amenable to being supplemented without bias in the resulting statistics. Misclassification bias will be evaluated to check the robustness of the SEER statistics. Objectives: 1) Evaluate the feasibility of supplementing specific selected cancer registry variables (race-ethnicity, birthplace, treatment, tumor biomarkers) with data from 3 defined sources: a) patient interview research studies, b) POC, and c) electronic health records (HER) data. 2) Evaluate the potential for improving SEER-based standard cancer reporting statistics (e.g., incidence, prevalence, treatment-specific survival) by augmenting race/ethnicity, birthplace, treatment, and tumor biomarkers registry data with supplementary data.
