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

非医院门诊治疗机构对新发癌症病例和首个疗程的信息少报是一个持续存在的问题，影响了使用基于人群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)评估独立肿瘤内科门诊（以造血疾病为重点）癌症病例的漏报情况；2)确定独立肿瘤内科门诊提供的癌症治疗数据的漏报情况；3)评估漏报情况对医院和门诊能否预测癌症生存差异的影响。

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.
