IGH mutation

This analysis provides insights into the clinical features and familial patterns of malignancy of individuals with POT1-TPD. Identification through genetic counseling and augmented cancer screening is paramount.

NGS revealed that a common progenitor cell with BCL2-IgH translocation and mutations in TP53, KMT2A, KMT2C, and KMT2D gave rise to two distinct subclones: one (CD5 + CD23+CD200+) CLL driven by mutations in TNFAIP3 and BCORL1, and the other (CD5-CD23-CD200-) driven by mutations in EP300, NOTCH1, and BCL2. This case highlights the significance of clonal heterogeneity in CLL and underscores the crucial role of MFC, flow sorting, and molecular genetics in diagnosing and understanding the complex evolution of this disease.

Successful fixed-duration regimens in CLL should achieve deep remission (i.e., undetectable minimal residual disease), sustain long-term progression-free survival, decrease the burden of treatment-related adverse events, and allow for re-treatment with minimal risk of drug resistance. Although fixed-duration treatment represents a positive step forward for most patients with CLL/SLL, the currently approved regimens often fall short in patients at high risk of progression. Continued research and development of next-generation drugs is essential to enhance efficacy and safety, ultimately improving outcomes in all patients with CLL/SLL.

Combining OGM and NGS analysis refined risk stratification beyond standard FISH panels and supports more precise, individualized management strategies in CLL. Prospective studies are warranted to evaluate the clinical utility of OGM-guided genomic profiling in contemporary treatment paradigms.

The primary first-line treatment options for CLL comprise continuous therapies based on the BTK inhibitors ibrutinib, zanubrutinib, or acalabrutinib, or fixed-duration regimens combining the BCL2 inhibitor venetoclax with obinutuzumab or the BTK inhibitors ibrutinib or acalabrutinib (with or without obinutuzumab). Selecting the appropriate targeted therapy requires careful evaluation of a multitude of factors, including molecular disease features (especially del[17p]/TP53 and IGHV mutational status), comorbidities, comedications, and the patient's preferences. Focusing on primary treatment options, we review data from the key controlled trials that support the first-line use of targeted therapies for patients with CLL, consider ongoing trials that may support clinical decision-making in the future, and assess the potential to personalize treatment regimens in CLL based on minimal residual disease status.

Combining ibrutinib with the GPX4 inhibitor RSL3 enhances ferroptosis and improves antileukemic efficacy in vivo. Notably, ACSL1 is selectively upregulated in U-CLL cells and represents a targetable metabolic enhancer of ferroptosis sensitivity, as shown in vivo. Our findings reveal that TFRC and ACSL1 are functionally distinct yet targetable nodes that govern ferroptosis vulnerability in CLL patients and may guide novel therapeutic strategies for high-risk patients.

The transition to targeted therapies has improved outcomes for high-risk CLL patients. Nevertheless, outcomes for high-risk CLL patients remain inferior to those reported in clinical trials, underscoring the need for real-world evidence and improved therapies.

Our data confirmed unfavourable prognostic value of IGLV321 for prediction of progressionfree survival and overall survival in CLL patients with M IGHV genes, regardless of radiation anamnesis.

This survey highlights gaps between international recommendations and Korean real-world practice, emphasizing the need for improved diagnostic availability, timely reimbursement of targeted agents, and development of Korea-specific clinical guidelines tailored to the Korean context.

Pirtobrutinib demonstrated superiority over BendaR in IRC-assessed PFS in treatment-naïve CLL/SLL. OS trends favored pirtobrutinib despite the study design allowing for crossover. Pirtobrutinib was well tolerated, consistent with its known safety profile, and more favorable than BendaR.
