IGF::OT::IGF SEER RRSS IMPROVING OUTPATIENT REPORTING OF CANCER OCCURRENCE AND TREATMENT; 9/19/16-9/18/17

新的癌症病例和非医院门诊治疗设施的第一个疗程的信息报告不足是一个持续存在的问题，影响了使用人口为基础的癌症登记数据的研究结果的普遍性和有效性。本研究的目的是：1）评价在独立的肿瘤内科门诊就诊的癌症病例报告不足的情况，重点是造血系统疾病，2）确定独立的肿瘤内科门诊提供的癌症治疗数据报告不足的情况，3）评价报告不足对医院与门诊是否预测癌症生存率差异的影响。

Underreporting of information on new cancer cases and first course of treatment by non-hospital outpatient treatment facilities is a persistent problem affecting the generalizability and validity of research findings using population-based cancer registry data. The objectives of this study are to: 1) Evaluate the under reporting of incident cancer cases seen at free standing medical oncology outpatient clinics, with a focus on hematopoietic diseases, 2) Determine the under reporting of cancer treatment data provided at free standing medical oncology outpatient clinics, 3) Evaluate the impact of under reporting has on whether hospitals verses outpatient settings predict differences in cancer survival.
