ABSTRACT
Chimeric antigen receptor (CAR) T-cell therapy is a revolutionary approach in the treatment of lymphoma. This review article provides an overview of the four FDA-approved CAR T-cell products for aggressive B-cell lymphoma, including diffuse large B-cell lymphoma and mantle cell lymphoma, highlighting their efficacy and toxicity as well as discussing future directions.
ABSTRACT
OBJECTIVES: Haematology patients are more likely to receive high intensity care near end of life (EOL) than patients with solid malignancy. Previous authors have suggested indicators of quality EOL for haematology patients, based on a solid oncology model. We conducted a retrospective chart review with the objectives of (1) determining our performance on these quality EOL indicators, (2) describing the timing of level of intervention (LOI) discussion and palliative care (PC) consultation prior to death and (3) evaluating whether goals of therapy (GOT), PC consultation and earlier LOI discussion are predictors of quality EOL. METHODS: We identified patients who died from haematological malignancies between April 2014 and March 2016 (n=319) at four participating McGill University hospitals and performed retrospective chart reviews. RESULTS: We found that 17% of patients were administered chemotherapy less than 14 days prior to death, 20% of patients were admitted to intensive care, 14% were intubated and 5% were resuscitated less than 30 days prior to death, 18% of patients received blood transfusion less than 7 days prior to death and 67% of patients died in an acute care setting. LOI discussion and PC consultation occurred a median of 22 days (IQR 7-103) and 9 days (IQR 3-19) before death. Patients with non-curative GOT, PC consultation or discussed LOI were significantly less likely to have high intensity EOL outcomes. CONCLUSIONS: In this study, we demonstrate that LOI discussions, PC consults and physician established GOT are associated with quality EOL outcomes for patients with haematological malignancies.
ABSTRACT
Acute promyelocytic leukemia (APL) is associated with severe coagulopathy leading to rapid morbidity and mortality if left untreated. The definitive diagnosis of APL is made by identifying a balanced reciprocal translocation between chromosomes 15 and 17. This t(15;17) results in a fusion transcript of promyelocytic leukemia (PML) and retinoic acid receptor alpha (RARA) genes and the expression of a functional PML/RARA protein. Detection of a fused PML/RARA genomic DNA sequence using fluorescence in situ hybridization (FISH) or by detection of the PML/RARA fusion transcript via reverse transcriptase polymerase chain reaction (RT-PCR) has revolutionized the diagnosis and monitoring of APL. Once confirmed, APL is cured in over 90% of cases, making it the most curable subtype of acute leukemia today. Patients with low-risk APL are successfully treated using a chemotherapy-free combination of all-trans retinoic acid and arsenic trioxide (ATO). In this review, we explore the work that has gone into the modern-day diagnosis and highly successful treatment of this once devastating leukemia.
