Additionally, HBx variants with Ser-101 increased p53 and ROS levels, whereas variants with Pro-101 did not. These dual mechanisms of HBx-induced ROS generation are likely significant in the pathogenesis of HBV and may contribute to liver diseases, including hepatocellular carcinoma.

Re-evaluation of the concept of basaloid follicular hamartoma associated with naevoid basal cell carcinoma syndrome: a morphological, immunohistochemical and molecular study. (PubMed, Pathology)

Targeted next-generation sequencing suggested that MYCN and GLI2/3 amplifications and TP53 mutations might be involved in progression of these follicular tumours to BCC. Our study confirms the high prevalence of BFH, representing up to 24% of skin tumours in NBCCS and potentially being BCC precursors.

Cytomorphology of Non-Small Cell Lung Carcinoma with MET Exon 14 Skipping Mutations (USCAP 2024)

One patient received Capmatinib and one patient Pembrolizumab. This study showed that NSCLC with METex14 are poorly differenciated tumors with necrotic background,multinucleation,atypical mitoses,and pleomorphic/sarcomatoid features. Larger studies are needed to confirm our preliminary findings. Routine NGS testing on cytological specimens is feasible and essential for METex14 testing and select patients with advanced lung NSCLC for targeted therapies.

MDM2 amplification is rare in gastric cancer. (PubMed, Virchows Arch)

Our targeted analysis of MDM2 in a well-characterized cohort of GC patients showed that MDM2 amplification is rare, of no specific histological phenotype, and may not be always mutually exclusive with TP53 mutations. Given the low number of cases, currently, no diagnostic or therapeutic recommendation related to MDM2 amplification can be given for GC of Western origin.

Furthermore, we examined the interplay between p53R172H and NF-kB and found that the p53R172H physically interacts with the NF-kB subunit RelA and facilitates its nuclear translocation. Conclusions Overall, we characterize how a common p53 mutation in PDAC co-opts non-coding regulatory DNA to augment the expression of selective chemokine genes and establishes an immunosuppressive TME to shield the therapeutic benefits of ICIs.

Severe manufacturing shortages of BCMA directed CAR-T therapy (idecel and ciltacel) are daunting with no clear solution in sight.

Aumolertinib Plus Anlotinib in Advanced NSCLC with Brain Metastasis: A Single-arm, Phase II Study (IASLC-WCLC 2023)

In addition, EGFR-TKIs combined with bevacizumab can further improve the efficacy, as reported in study JO25567 and NEJ026. Aumolertinib plus anlotinib showed preliminary efficacy as first-line therapy in EGFR-mutant NSCLC patients with brain metastases. The initial subgroup results may demonstrated superior activity of aumolertinib plus anlotinib in patients with multiple intracranial metastases or EGFR 19Del positive. And although with comutations, NSCLC patients with brain metastasis can still benefit from aumolertinib plus anlotinib.

Comprehensive Cancer Genomic Profiling In Matched Primary Tumor And Brain Metastasis Samples Of Ovarian Cancer Patients: A Single-Institution Case Series. (ESGO 2023)

A phylogenetic analysis is still ongoing at our center. This more comprehensive evaluation may pave the way toward a more precise understanding of the genetics underneath the development of BM, potentially revealing novel molecular targets and leading to prospective future studies and more personalized treatment.
