Cancer registry data often lack complete chemotherapy and radiation therapy information. To conduct treatment disparity surveillance, we linked 2005-2009 Nebraska Cancer Registry data with Nebraska hospital discharge data. Due to the high quality of both datasets and the proposed linkage procedure, we had a linkage rate of 97 percent. We demonstrate the utilization of the linked dataset in case finding, treatment update, and treatment surveillance. The results show that the linked dataset is likely to identify up to 5 percent of potential missed cases. We investigated the use of radiation therapy in treating colorectal and breast cancers as case-finding examples. The linked dataset found 12 percent and 14 percent more treatment cases for colorectal and breast cancer patients, respectively.
癌症登记数据通常缺乏完整的化疗和放疗信息。为了进行治疗差异监测，我们将 2005-2009 年内布拉斯加州癌症登记数据与内布拉斯加州医院出院数据进行了链接。由于两个数据集的高质量和拟议的链接程序，我们的链接率达到了 97%。我们展示了链接数据集在病例发现、治疗更新和治疗监测中的利用。结果表明，链接数据集有可能发现多达 5%的潜在漏报病例。我们以结直肠癌和乳腺癌的放疗使用情况为例，研究了放疗在病例发现中的应用。链接数据集分别发现结直肠癌和乳腺癌患者的治疗病例增加了 12%和 14%。
