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少报新的癌症病例和第一疗程的信息是一个长期存在的问题，影响了使用基于人口的癌症登记数据的研究结果的概括性和有效性。这项研究的目的是：1)评估独立内科肿瘤科门诊看到的癌症病例报告不足的情况，重点关注造血疾病；2)确定独立肿瘤内科门诊所提供的癌症治疗数据的报告不足的情况；3)评估报告不足对医院和门诊是否预测癌症生存率的差异的影响。

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.
