NTSR, under the direction of Claudine Isaacs, MD and Beth Peshkin, MS, CGC, provides centralized patient recruitment services for nontherapeutic human trials. The NTSR implements a universal protocol and consent which includes collection of core data elements from patients at GUMC with and without cancer. Patients are also consented for collection of biospecimens and tissue, and for future contact for enrollment into specific studies and follow-up. The NTSR also provides services to investigators including data entry and programming, medical record abstraction, and risk assessment counseling. The NTSR works closely with Tissue Culture Shared Resource (TCSR) and Histopathology and Tissue Shared Resource (HTSR) to provide investigators with access to patients and data that can be linked to biospecimen samples as well as tumor and non-tumor tissue.

The NTSR also encompasses the Familial Cancer Registry (FCR), which is an integrated and comprehensive resource of individuals at high genetic risk for cancer and includes detailed demographic data, family history information, medical history, cancer risk factors, tissue from surgeries (benign and malignant), tissue micro-array, and biospecimen, all of which can be linked securely and confidentially to results of genetic testing. The majority of participants are members of high-risk breast and ovarian cancer families. Participants are contacted annually to obtain updated personal and family history.
