Surveillance, Epidemiology and End Results (SEER) data from the National Cancer Institute (NCI) provide reliable information about cancer incidence. However, because SEER data are geographically limited and have a 2-year time lag, we evaluated whether Medicare data could provide timely information on cancer incidence. Comparing Medicare women hospitalized for breast cancer with women reported to SEER, Medicare data had high specificity (96.6 percent), yet low sensitivity (59.4 percent). We conclude that Medicare hospitalization data can identify incident cases for cancers that usually require inpatient hospitalization. For cancers that often only receive outpatient treatment, such as breast cancer, additional Medicare data, such as physician bills, are needed to understand the entirety of treatment practices.
美国国家癌症研究所（NCI）的监测、流行病学和最终结果（SEER）数据提供了有关癌症发病率的可靠信息。然而，由于SEER数据在地理上存在局限性且有两年的时间滞后，我们评估了医疗保险数据是否能提供有关癌症发病率的及时信息。将因乳腺癌住院的医疗保险女性与向SEER报告的女性进行比较，医疗保险数据具有较高的特异性（96.6%），但敏感性较低（59.4%）。我们得出结论，医疗保险住院数据可以识别通常需要住院治疗的癌症的发病病例。对于那些通常只接受门诊治疗的癌症，如乳腺癌，需要额外的医疗保险数据，如医生账单，来了解整个治疗情况。
