Safety and efficacy of anti-BCMA CAR-T cell therapy in older adults with multiple myeloma: A systematic review and meta-analysis.

INTRODUCTION: Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR-T) therapy is transforming the care of patients with relapsed/refractory multiple myeloma (MM). Unfortunately, despite being a disease of older adults these patients remain under-represented in most pivotal clinical trials. We performed a systematic review and proportion meta-analysis of prospective clinical trials and observational studies of anti-BCMA CAR-T therapy in patients with MM with the aim to determine the efficacy and safety of this therapy in older adults (≥65 years). MATERIALS AND METHODS: We searched the Pubmed, Scopus, Web of Science (WOS), Ovid, Embase, CENTRAL, and CINAHL databases through September 9, 2022 and abstracts from the American Society of Hematology (ASH) Annual Meeting 2022. Primary outcome measures included overall response rate (ORR), rates of cytokine release syndrome (CRS), and immune cell-effector-associated neurotoxicity syndrome (ICANS). study was registered with PROSPERO (study number: CRD42022334287). RESULTS: After screening 2218 references, 14 studies were included for data extraction, with a total of 558 patients, 26.2% (n = 146) of whom were older adults. The pooled ORR amongst this population was 93%, which was comparable to the ORR of 86% amongst younger patients. In older adults, the rates of CRS (any grade) and grade ≥ 3 were 95% and 21%, respectively. For younger patients, the pooled rate of CRS (any grade) and grade ≥ 3 CRS was 91% and 20%, respectively. The rate of ICANS (any grade) in older adults was 15%, which was higher than that observed in those <65 years. CONCLUSION: Older adults experience comparable outcomes to younger patients with anti-BCMA CAR-T therapy, albeit with numerically higher rates of neurotoxicity.

Frequency and timing of other primary cancers in patients with chronic lymphocytic leukemia (CLL): a 17-year longitudinal study.

Patients with chronic lymphocytic leukemia (CLL) are known to be at a higher risk of developing other primary cancers (OPC). Identifying latency and risk factors associated with OPCs in CLL is of interest as select patients may potentially benefit from early treatment of CLL with targeted therapies to improve immune surveillance. In this single-center retrospective study, 16.9% of 969 patients with CLL were diagnosed with an OPC. Interestingly, 44% of OPCs were diagnosed prior to the CLL diagnosis, including 30% that were diagnosed >1 year prior. This included a majority of genitourinary cancers and melanoma skin cancers. Patients with CLL and an OPC were older than pts with no OPCs but no other risk factors for developing OPCs were identified. Our data suggest that not only are patients with CLL at higher risk of developing OPCs and warrant appropriate cancer surveillance, but the risk also precedes CLL diagnosis by several years.

Geriatric assessment in older adults with non-Hodgkin lymphoma: A Young International Society of Geriatric Oncology (YSIOG) review paper.

Non-Hodgkin lymphoma (NHL) is a disease of older adults, with a median age at diagnosis of 67 years. Treatment in older adults with NHL is challenging. The aging process is associated with a decline in functional reserve that varies among individuals, and results in an increasing risk of treatment-related toxicity and mortality. Chronological age and performance status fail to capture the multidimensional and heterogeneous nature of the aging process. A geriatric assessment (GA) screens multiple geriatric domains and provides a more accurate assessment of functional reserve. Several abbreviated GA tools have been developed for use in oncology clinics and help identify patients at high risk for chemotherapy-related toxicity and mortality. In this review, we explore GA tools validated for use in patients with NHL. We discuss the evidence behind GA-guided treatment in NHL and present a suggested approach to assessing frailty in this patient population.

Acute lymphoblastic leukemia presenting as a breast lump: A report of two cases.

Extra-medullary leukemic infiltration of the breast by acute lymphoblastic leukemia (ALL) is very rare. We report two cases of ALL presenting as breast masses and diagnosed on fine-needle aspiration (FNA). Our first patient, a post-partum 30-year-old female, developed bilateral breast lumps in her last trimester of pregnancy and complained of easy fatigability. Our second patient, a 14-year-old girl, presented with a right-breast lump of 1-week duration. She had received treatment for ALL 1 year back and had been in complete remission for the last 1 year. FNA of the breast nodules done in both the cases revealed diffuse infiltration by lymphoblasts. Subsequent hematological investigations confirmed bone marrow involvement by ALL in the first case and extra-medullary relapse in the second case. Fine-needle aspiration cytology (FNAC) is an easy and cost effective method for the early diagnosis of metastatic leukemic infiltration, avoiding unnecessary excisional biopsies in such cases.
