Altered TP53, CDKN2A, ATM, EPHA7, POT1, CHEK1, GRIN2A, and EGFR Predict Shorter Survival in Penile Squamous Cell Carcinoma. (PubMed, Mod Pathol)

We detected 160 alterations with potential treatment implications, with 21.2% of samples showing alterations in the homologous recombination pathway. To the best of our knowledge, this study describes the largest cohort of pSCC with complex molecular-pathological, clinical, and prognostic analysis correlating with prognosis.

Sintilimab combined with anlotinib and chemotherapy as second-line or later therapy in extensive-stage small cell lung cancer: a phase II clinical trial. (PubMed, Signal Transduct Target Ther)

The trial design involved a combination therapy (sintilimab, anlotinib, and nab-paclitaxel) administered over six 21-day cycles, followed by maintenance sintilimab therapy. ctDNA analysis indicated that low on-treatment blood tumor mutation burden was associated with longer PFS and OS and a potential role of KMT2D mutation in treatment resistance. This combination therapy shows promising efficacy and a manageable safety profile as a second-line or later treatment for ES-SCLC, with genomic insights providing potential biomarkers for treatment response.

Loss of CREBBP and KMT2D cooperate to accelerate lymphomagenesis and shape the lymphoma immune microenvironment. (PubMed, Nat Commun)

Their combined deficiency preferentially impairs activation of immune synapse-responsive super-enhancers, pointing to a particular dependency for both co-activators at these specialized regulatory elements. Together, our data provide an example where chromatin modifier mutations cooperatively shape and induce an immune-evasive microenvironment to facilitate lymphomagenesis.

Emergence of Highly-Plastic B Cell States Cooperates with Early Immune Microenvironment Remodeling to Drive Follicular Lymphomagenesis (ASH 2023)

In conclusion, our results provide a high-resolution view of events spanning FL progression and indicate a major role of early TME remodeling in establishing a suitable niche for progression. Early intervention aimed to target the B cell-tumor microenvironment interactions driving intra-tumoral heterogeneity may represent a promising therapeutic avenue against early disease and prevention of FL recurrence.

A Multi-Omic Study Unveils a Clonal Population of TET2-Mutated Infiltrating T-Cells in Germinal Center B Cell Lymphomas (DLBCL and FL) (ASH 2023)

Moreover, our findings support the critical role of the tumor microenvironment for the persistence and development of the tumor clone. The finding of a TET2 mutated clone in the infiltrating T cells of all the patients is particularly noteworthy, as it may suggest the possible presence of clonal lymphopoiesis.

Integrative Genomic and Transcriptomic Analysis Reveals Targetable Vulnerabilities in Angioimmunoblastic T-Cell Lymphoma (ASH 2023)

Low mRNA expression of PHLPP2 predicted poor prognosis (p=.03) and engineered PHLPP2 loss showed enhanced PI(3)K activation and FOXO1 inactivation in CD4+ T-cells in-vitro. Thus, we defined the genomic landscape for AITL, which is largely characterized by epigenetic alterations, TCR signaling and PI3K/AKT dysregulation, which may be amenable for therapeutic targeting.

Mutations in Histone Lysine Methyltransferase Genes Are Associated with Autoimmune Cytopenias (ASH 2023)

Conclusion We report for the first time that patients with autoimmune cytopenias have a high frequency of variants in MT genes. Median allelic frequency close to 50% suggests potential germline predisposition to immune dysregulation and autoimmunity however further studies are needed to better understand the impact of these observations.

Longitudinal Noninvasive Surveillance & Fragmentomic Characterization of Follicular Lymphoma (ASH 2023)

Depth of response was similar between rituximab monotherapy and cytotoxic regimens, with median -2.2 log10 fold change from baseline...Frequent detectable MRD in radiographic remission suggests that integrating molecular surveillance may augment serial imaging in the long-term management of FL. Simultaneous inferred gene expression from FL cfDNA appears to hold promise, including for noninvasive detection of transformation.
