The mission of the NCI/CCR/LP Clinical Cytogenetics Section is to provide state-of-the-art diagnostic services for patients evaluated and treated at the Mark O. Hatfield Clinical Research Center;to perform clinical translational cancer cytogenetics research;and to teach and mentor students, residents, and fellows in the principles and practices of clinical cytogenetics service and research. The goals of this project, which comprises 70 percent of the effort of the section, are to provide diagnostic service and research testing on samples from patients entered on clinical research protocols by NCI and other Institute physicians, to collaborate on NCI clinical translational research protocols, and to teach and mentor students, residents, and fellows. The Clinical Cytogenetics Section is the only intramural NIH laboratory performing cytogenetics diagnostic services. The laboratory is inspected and certified by the College of American Pathologists, the Joint Commission for Accreditation of Hospitals, and the Clinical Laboratory Improvement Act of 1988. We currently perform highly complex routine and molecular cytogenetic testing on patient samples from several institutes (NCI, NIAID, NICHD) and the Clinical Center Department of Laboratory Medicine. In greater than 90 percent of cases the testing is for acquired chromosome abnormalities in premalignant and malignant disorders, and in the remaining cases is for constitutional chromosome abnormalities. The results of our testing are used for diagnosis, classification, prognosis, and treatment planning for patients. They also provide critical information regarding the gene regions that may be important for tumor initiation and progression, and thus serve as a starting point for further molecular biologic investigations of malignant diseases. Section members are conducting routine diagnostic and research fluorescence analyses of patients entered on NCI clinical research protocols. Dr. Arthur is an Associate Investigator on eight active protocols as follows: a. 97-C-0178 Fludarabine Treatment of Chronic Lymphocytic Leukemia (CLL): cDNA Microarray Gene Expression Analysis, and Pre-Clinical Bone Marrow Transplant/ Immunotherapy Studies, PI: Wyndham Wilson, M.D., Ph.D. b. 01-C-0125 Pilot Study of Non-myeloablative, HLA-matched Allogeneic Stem Cell Transplantation for Pediatric Hematopoietic Malignancies, PI: Alan S. Wayne, M.D. c. 02-C-0052 Etiologic Investigation of Cancer Susceptibility in Inherited Bone Marrow Failure Syndromes, PI: Blanche Alter, M.D. M.P.H. d. 04-C-0079 Pediatric Phase I Trial of BL22 for Refractory CD22-Positive Leukemias and Lymphomas, PI: Alan S. Wayne, M.D. e. 04-C-0102 Hematologic Malignancy Biology Study, PI: Alan S. Wayne, M.D. f. 04-C-0168 Pediatric Phase I Trial of LMB-2 for Refractory CD25-Positive Leukemias and Lymphomas, PI: Alan S. Wayne, M.D. g. 04-C-0095 A Pilot Study of Intensified Lymphodepletion Followed by Autologous Hematopoietic Stem Cell Transplantation in Patients with Severe Systemic Lupus Erythematosus, PI: Steven Z. Pavletic, M.D. h. 08-C-0105 """"""""Natural History Study of Monoclonal B Cell Lymphocytosis (MBL) and Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL),"""""""" PI: Wyndham H. Wilson, M.D., Ph.D. The cytogenetics data generated as part of these studies are clinically useful for diagnosis, classification, and treatment planning for patients. They are also important for monitoring patient response to experimental treatment, and for correlation with other research studies. They have the potential for discovery of new clinical-pathological associations among these diseases and of biological mechanisms that may be targeted with future therapies. Finally, section members teach and mentor students, residents, and fellows in the principles and practices of clinical cytogenetics service and research. In addition to mentoring three summer students and two postdoctoral fellows, Dr. Arthur is a member of the NCI/CCR/LP Resident, NCI/CCR/LP Hematopathology Fellow, and NHGRI Clinical Cytogenetics Fellow faculties. In this role, she provides didactic lectures and laboratory rotations for all residents and fellows enrolled in these training programs. In summary, the Clinical Cancer Cytogenetics program provides unique state-of-the-art clinical cytogenetics service, essential education and service to the LP and the CCR, and wide collaborative support for NCI clinical and translational research programs.
