Alex F. Herrera, MD, on Previously Untreated DLBCL: Circulation Tumor DNA and Risk Profiling
2022 ASH Annual Meeting and Exposition
Alex F. Herrera, MD, of the City of Hope National Medical Center, discusses results from the POLARIX study, which showed that circulating tumor DNA (ctDNA) analysis has prognostic value for patients with previously untreated diffuse large B-cell lymphoma. Patients who did not achieve 2.5 or greater log-fold change and/or did not have ctDNA clearance following one cycle of polatuzumab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone had inferior outcomes than those who did. Early changes in ctDNA levels may be of use in risk-adapted trial designs to identify patients in need of alternative treatment. (Abstract 542).

Smita Bhatia, MD, MPH, of the Institute for Cancer Outcomes and Survivorship, University of Alabama at Birmingham, discusses study findings that showed key somatic mutations in the peripheral blood stem cell product increases the risk of developing therapy-related myeloid neoplasms (Abstract 119).

Jorge E. Cortes, MD, of Georgia Cancer Center at Augusta University, discusses new findings on vodobatinib, which was administered to patients with chronic-phase Philadelphia chromosome–positive chronic myeloid leukemia (CML) and appeared to be efficacious and safe in people who had received therapy with two or three prior tyrosine kinase inhibitors (TKIs). Vodobatinib remains a potential option for these highly refractory patients. A phase II study (NCT02629692) of vodobatinib is ongoing in CML patients whose disease has failed to respond to three or more TKIs, including ponatinib (Abstract 84).

Tomohiro Aoki, MD, PhD, of the University of British Columbia and the Centre for Lymphoid Cancer at BC Cancer, discusses a novel prognostic model applicable to patients with relapsed or refractory classical Hodgkin lymphoma who were treated with autologous stem cell transplantation. The model has shown the interaction between the biomarker CXCR5 on HRS cells (Hodgkin and Reed/Sternberg cells, hallmarks of Hodgkin lymphoma) with specific follicular T helper cells and macrophages, a prominent crosstalk axis in relapsed disease. This insight opens new avenues to developing predictive biomarkers (Abstract 71).

Francesco Maura, MD, of the University of Miami, Sylvester Comprehensive Cancer Center, discusses his team’s findings in which they defined a comprehensive catalogue of genomic determinants of response to DKRd (carfilzomib, lenalidomide, dexamethasone) in newly diagnosed multiple myeloma. The researchers have identified a number of new genomic alterations that explain resistance to the agents currently used in combination regimens (Abstract 470).

Eileen M. Boyle, MD, PhD, of the Perlmutter Cancer Center, NYU Langone Health, discusses Fc-mediated antibody effector function, inflammation resolution, and oligoclonality and their role in predicting sustained measurable residual disease negativity in patients with newly diagnosed multiple myeloma who were treated with immunotherapy regimens. For the first time, an analysis of T-cell receptors shows that oligoclonal profiles seen on treatment may influence the fitness of the immune response (Abstract 100).
