Relapse and metastasis are the major challenges that stand in the way of cancer healing and survival, mainly attributed to cancer stem cells (CSCs). Their capabilities of self-renewal and tumorigenic potential leads to treatment resistance development. CSCs function through signaling pathways such as the Wnt/β-catenin cascade.

Ethnic and racial disparities persist in the prevalence, diagnosis, management, and outcomes of MM. These disparities are multifaceted and intersect with various factors, including demographics, geography, socioeconomic status, genetics, and access to healthcare.

- CAR T-cell therapy shows strong initial results for treating relapsed refractory multiple myeloma, but most patients eventually relapse, often within 5 months.
- In a study of 139 patients who relapsed after CAR T-cell therapy, different salvage therapies were analyzed, revealing that bispecific antibodies, like talquetamab and teclistamab, had the best overall and complete response rates.
- The presence of extramedullary disease at relapse was linked to poorer outcomes, but bispecific antibodies improved survival rates, suggesting they should be the standard treatment for patients relapsing after CAR T-cell therapy.
Past studies described occasional patients with myeloid neoplasms (MN) and coexistent large granular lymphocytic leukemia (LGLL) or T-cell clonopathy of unknown significance (TCUS), which may represent expansion of myeloid clonal hematopoiesis (CH) as triggers or targets of clonal cytotoxic T cell reactions. We retrospectively analyzed 349 LGLL/TCUS patients, 672 MN patients, and 1443 CH individuals to establish the incidence, genetic landscape, and clinical phenotypes of CH in LGLL. We identified 8% of cases overlapping with MN, while CH was found in an additional 19% of cases (CH + /LGLL) of which TET2 (23%) and DNMT3A (14%) were the most common.

This study aimed to explore whether both measured TL and genetic disposition for TL predict dimensions of cognitive performance in a longitudinal sample of older UK adults.
Methods: We analysed data from PROTECT study participants aged ≥50 years without a dementia diagnosis, who had completed longitudinal cognitive testing.
