Seattle Cancer Care Alliance Clinicians Present New Research at 63rd Annual Meeting of the American Society of Hematology

Key research spans CAR T-cell therapies and treatments for myeloma, leukemia and more.

SEATTLE–(BUSINESS WIRE)–#ASH21–Seattle Cancer Care Alliance (SCCA), the only National Comprehensive Cancer Network (NCCN)-designated cancer center in Washington state, today announced that more than 20 of the organization’s clinicians will showcase new research at the 63^rd Annual Meeting of the American Society of Hematology (ASH), taking place December 11-14, 2021, in Atlanta.

SCCA clinicians and researchers will unveil findings on areas of investigation into treatments for patients with various hematological malignancies, including lymphoma, leukemia and myeloma. Clinicians will discuss findings on CAR-T therapies targeting CD20 cells, multiple myeloma and chronic lymphocytic leukemia. Key research also includes findings on hematopoietic stem cell transplant (HCT) and outcomes and utilization for a range of treatments.

“Our team at Seattle Cancer Care Alliance is committed to understanding, developing and advancing cutting-edge cancer treatments,” said Nancy Davidson, MD, president and executive director of SCCA. “Our researchers and clinicians are known leaders in the hematological clinical research space; we are proud of their work and continued contributions to this space. We look forward to energized discussion on the implications of the research presented and the role the research plays in contributing to expanded treatment options for patients.”
