Alba Rodriguez-Meira, DPhil, on TP53-Mutated Leukemic Transformation in Myeloproliferative Neoplasms
2021 ASH Annual Meeting & Exposition
Alba Rodriguez-Meira, DPhil, of the University of Oxford, discusses a comprehensive analysis of the genetic, cellular, and molecular landscape of TP53-mediated transformation, providing insights into the evolution of chronic hematologic malignancies toward an aggressive acute leukemia. Because TP53 is the most commonly mutated gene in human cancer, these findings may well be of broad relevance (Abstract 3).

Manali Kamdar, MD, of the University of Colorado Cancer Center, discusses phase III results from the TRANSFORM study, which suggest that lisocabtagene maraleucel, a CD19-directed CAR T-cell therapy, improved outcomes with a favorable safety profile and may be a potential new standard of care for second-line treatment of patients with relapsed or refractory large B-cell lymphoma (Abstract 91).

Talha Badar, MD, of the Mayo Clinic, discusses the near-universal poor outcomes for patients with TP53-mutated acute myeloid leukemia and the findings that show allogeneic stem cell transplantation appears to improve the long-term survival in a subset of these patients. Effective therapies may successfully bridge patients to transplant and prolong survival for those who are transplant-ineligible (Abstract 797).

Paolo Ghia, MD, PhD, of the Università Vita-Salute San Raffaele and IRCCS Ospedale San Raffaele, discusses disease-free survival results from the measurable residual disease cohort of the phase II CAPTIVATE trial. This multicenter trial focuses on first-line ibrutinib plus venetoclax in patients with chronic lymphocytic leukemia (Abstract 68).

Sangeetha Venugopal, MD, of The University of Texas MD Anderson Cancer Center, discusses a retrospective analysis of 562 patients with treated secondary acute myeloid leukemia and prior exposure to hypomethylating agents (HMAs). The results showed that an HMA plus venetoclax yielded significantly higher overall response rates and improved overall survival compared with intensive chemotherapy or low-intensity chemotherapy, particularly in patients 60 years or older who had a karyotype without adverse risk (Abstract 794).

Masayuki Umeda, MD, of St. Jude Children's Research Hospital, discusses his research which showed that UBTF-TD (upstream binding transcription factor-tandem duplications) define a unique subtype of acute myeloid leukemia that previously lacked a clear oncogenic driver. UBTF-TD is associated with FLT3-ITD and WT1 mutations, adolescent age, and poor outcomes. These alterations are critical for future risk-stratification for this patient cohort.
