Hematology

On Dec. 4, Mayo Clinic Laboratories will host the Friday Satellite Symposium A Case-Based Workshop: Clinical and Laboratory Aspects of Hemophilia and Thrombosis, preceding the 62nd American Society of Hematology Annual Meeting and Exposition.

Min Shi, M.D., Ph.D., a hematologist and co-director of Mayo Clinic's Flow Cytometry Laboratory, explains recent updates to the B-cell lymphoblastic leukemia minimal residual disease flow cytometry assay. This test is used to identify minimal residual disease in patients with a previously confirmed diagnosis of B-cell lymphoblastic leukemia who have completed chemotherapy, immunotherapy or bone marrow transplantation.

The results are part of a comprehensive study of 16,175 cases performed at Mayo Clinic over an 11-year period.

Horatiu Olteanu, M.D., Ph.D., gives an overview of the new T-cell receptor (TCR) β-chain constant region (TRBC1) flow cytometry marker, which is now included in Mayo Clinic Laboratories' routine diagnostic T-cell flow cytometry panel. He discusses when this testing should be ordered, how the addition of TCRBC1 compares to previous testing approaches, and how this marker can assist ordering physicians.

Matt Millen, ex-pro NFL player, who played on four Super Bowl-winning teams underwent a nearly six-year medical journey in search for answers. Finally, he was diagnosed with amyloidosis using a new testing methodology at Mayo Clinic.

Mayo Clinic Laboratories provides evaluation and consultation for the diagnosis and treatment of patients with hereditary and acquired hematologic disorders.

Linda Baughn Ph.D. gives an overview of this new test available through Mayo Clinic Laboratories. She discusses when this testing should be ordered, how this testing improves upon other testing approaches, and what clinical action can be taken due to the results of this testing.

In this month’s “Hot Topic,” Curtis Hanson, M.D., will discuss the use of laboratory-based prognostic markers in patients with chronic lymphocytic leukemia (CLL). He will also highlight the importance of molecular analyses for IGHV and TP53 sequencing in these patients.

David Viswanatha, M.D., a hematopathologist and co-director of the molecular hematology and complete genome sequencing laboratories at Mayo Clinic, provides an overview of BCR/ABL1 testing, discusses the best testing methods, NCCN/ELN criteria guidelines, why FISH testing is no longer routinely available at Mayo Clinic, and what test to order at what time for CML patients.

Curtis Hanson, M.D., discusses the importance of detecting immunoglobulin heavy-chain variable region gene (IGHV) when acquiring prognostic and potentially therapeutic information in chronic lymphocytic leukemia (CLL) patients in CAP TODAY.

The current diagnostic tools in a pathologist’s arsenal sometimes cannot provide a clear distinction between primary mediastinal large B-cell lymphoma (one of the few lymphomas more common in younger women) and diffuse large B-cell lymphoma, the most common type of non-Hodgkin’s lymphoma overall.

The standard laboratory test to diagnose multiple myeloma dates back to the Eisenhower administration. Research at Mayo Clinic spearheaded by David Murray, M.D., Ph.D. (PATH ’10), and fueled by his experience as an industrial chemist has led to a new assay to screen and diagnose the disease.

In this month’s “Hot Topic,” Rajiv Pruthi, M.B.B.S., will discuss different types of hemophilia along with their pathologic basis. He will also cover various types of factor assays such as one stage and chromogenic factor assays for diagnosis and their role in management of hemophilia.
