A broader role may be rational given MCL’s propensity for profound but inconsistent radiosensitivity. Common molecular alterations in MCL impact prognosis, namely TP53 mutations (TP53mut). TP53mut can influence systemic therapy choices but its impact on radiosensitivity, or RT decision making is unclear. Better understanding could guide precision radiotherapy.</p><p><b>Methods:</b> We analyzed patients (pts) treated with RT for MCL from 2010 to 2024, focusing on a cohort with next generation sequencing (NGS) for somatic genetic alterations (<i>n</i> = 66). Age and stage at RT, treatment intent, relapsed status, site of RT, and prior systemic therapy were collected. Sites treated in pts with TP53mut versus without TP53mut (TP53wt) were compared. Lesion SUV and diameter, extranodal (EN) status of the treated site, blastoid histology, RT dose, and metabolic response at first assessment were compared. Additionally, sites receiving very low dose radiotherapy (VLDRT, 4 Gy) and sites of local failure (LF) were analyzed.</p><p><b>Results:</b> 66 patients were identified, treated to 97 sites. 84 sites (87%) were treated in the relapsed setting. 54 sites (56%) were localized relapsed or early-stage disease.

Median RT dose was 30 Gy (4–40 Gy), median lesion diameter was 3.5 cm (0.9–22 cm), and median SUV max was 7.5 (0–61.6). 80% (<i>n</i> = 77) of sites had available PET response assessment at a median of 1.7 months (0.1–7.1) post-RT.

Alternatively, lymphoma may be promoted by the clonal and pro-inflammatory tumor microenvironment derived from CH. In this study we aimed to determine: (i) CH prevalence in newly diagnosed DLBCL; (ii) clinical impact of CH; (iii) correlation between CH and DLBCL genetic lesions; (iv) co-occurrence frequency of DLBCL driver and CH mutations at the single cell level; (v) enrichment of CH in cells of the lymphoma microenvironment compared to blood.</p><p><b>Methods:</b> Patients (<i>n</i> = 387) from the IOSI-EMA003 and SAKK38/19 trials were analyzed. CH mutations were identified in genomic DNA using a myeloid panel, while a lymphoid panel detected DLBCL mutations, somatic copy number abnormalities, and <i>BCL6</i> fusions in plasma cfDNA. Multiomic scDNA-seq and immunophenotyping of paired peripheral blood (PB) or bone marrow (BM) and disaggregated lymph nodes of 6 patients were performed. A custom Tapestri (MissionBio) panel targeted CH mutations and barcoded the dominant DLBCL clone by covering trunk oncogene mutations, enabling simultaneous genotyping and phenotyping of B cells, T cell subtypes, and myeloid cells. To assess whether CH-bearing myeloid cells support DLBCL in vitro: (i) BM cells from <i>Tet2</i> knockout (KO) and control mice were differentiated into macrophages and co-cultured with a <i>Tp53</i> KO murine B-cell lymphoma line; (ii) biallelic <i>TET2-</i>KO human THP1 monocytic cells, were differentiated into macrophages and co-cultured with DLBCL cell lines.

All patients received induction treatment with pembrolizumab (200 mg intravenously on day 1 in each 21-day cycle for 6 cycles) concurrently with radiotherapy (a total dose of 50–54 Gy). The patients achieved complete remission (CR), partial remission (PR), or stable disease (SD) have been given pembrolizumab 200 mg every 21 days as a maintenance up to 2 years.

Despite its prevalence, research on fusion genes in T-LBL, particularly their distribution and prognostic implications, remains limited. This study aimed to elucidate the frequency of fusion genes in Chinese pediatric T-LBL patients and explore their potential impact on prognosis, thereby providing new insights for clinical management.</p><p><b>Methods:</b> We collected data from 552 pediatric T-LBL patients (aged ≤ 16 years) treated at multiple centers of the China Network of Childhood Lymphoma (CNCL), with fusion gene testing results available for 180 patients. Sequencing-based methods were used to detect fusion genes, and statistical analysis was performed to investigate their associations with patient clinical outcomes.</p><p><b>Results:</b> Among the 180 patients analyzed, 105 (58.3%) were found to harbor fusion genes, with a total of 40 distinct fusion genes identified. The higher percentage of fusion genes were <i>SIL</i>::<i>TAL1</i> (<i>n</i> = 40, 22.2%), <i>MLL</i> fusions (<i>n</i> = 20, 11.1%), <i>TCR</i> partner-related fusions (<i>n</i> = 11, 6.1%), <i>ABL1</i> fusions (<i>n</i> = 9, 5%), <i>NOTCH1</i> fusions (<i>n</i> = 7, 3.9%), and <i>SET</i>::<i>CAN</i> (<i>n</i> = 7, 3.9%) (Figure 1a). These findings highlight the genetic heterogeneity of T-LBL in pediatric patients.</p><p>Prognostic analysis revealed that patients with <i>NOTCH1</i> fusions had significantly poorer event-free survival (EFS) and overall survival (OS) compared to those without <i>NOTCH1</i> fusions (EFS, <i>p</i> < 0.0001; OS, <i>p</i> = 0.00013, Figure 1b,c). The identified <i>NOTCH1</i> fusion types included <i>IKZF2</i>::<i>NOTCH1</i> (<i>n</i> = 4, 57%), <i>MIR142</i>::<i>NOTCH1</i> (<i>n</i> = 2, 29%) and <i>IKZF1</i>::<i>NOTCH1</i> (<i>n</i> = 1, 14%), all of which are associated with poor outcomes. We further analyzed the relationship between <i>NOTCH1</i> mutations and <i>NOTCH1</i> fusions, and there was no obvious evidence of co-occurrence or mutual exclusivity between these genetic events. Notably, although <i>NOTCH1</i> mutations are generally associated with favorable outcomes in pediatric T-LBL patients, the cooccurrence of <i>NOTCH1</i> fusions appeared to diminish this benefit, showing a trend toward poorer prognosis (<i>p</i> = 0.056). These findings indicate that <i>NOTCH1</i> fusions may serve as potential biomarkers for adverse prognosis in pediatric patients with T-LBL.
