Type B lactic acidosis is a rare complication of hematologic malignancies. The exact mechanism of this process is not well understood. Because caregivers may not be aware of the association of type B lactic acidosis with hematologic malignancies, it may go unrecognized as a cause of acidosis in these patients. We report the cases of 7 patients with type B lactic acidosis who were cared for by members of the Brown Medical School Hematology/Oncology Division. Of the 7 patients reported, 5 had lymphomas and 2 had chronic lymphocytic leukemia. One of the lymphomas was a T-cell lymphoma. Of the patients we were able to evaluate, there did not seem to be a unique cluster of differentiation marker in association with type B lactic acidosis. We also review 14 additional cases, most reported since 2001. From our review of the literature, we suggest that a deficiency of thiamine or riboflavin may play a more pivotal role than previously recognized in the development of type B lactic acidosis associated with malignancy. Further investigation should be undertaken to learn if thiamine or riboflavin replacement might be useful in treating this disorder.

DNMT3A codes for a DNA methyl transferase enzyme that plays a central role embryogenesis. Somatic mutations in this gene have been associated with tumorigenesis and are associated with a number of cancers. The recently described Tatton-Brown-Rahman syndrome (TBRS) is due to heterozygous germline mutations in the DNMT3A gene. So far, only one case of hematological malignancy associated with TBRS have been reported. Here, we describe the first case presenting with TBRS and medulloblastoma. We also discuss the associations between mutations in DNMT3A found in TBRS, AML, and medulloblastoma.

With the enormous progress made in treatment and management, many oncologists have called this the golden age of chronic lymphocytic leukemia (CLL). The past few years alone have seen the approval of multiple agents, including small molecule inhibitors that have led to longer, more durable periods of disease control. However, the introduction of these new drugs into the armamentarium has raised an important question regarding standard of care: is there still a role for chemoimmunotherapy in the first-line setting? At the NCCN 2019 Annual Congress: Hematologic Malignancies, Drs. William G. Wierda and Jennifer R. Brown presented opposing sides of the debate.
