Incidental finding of a pathogenic mosaicism in the NF1 gene detected by near infrared fundus imaging - a case report. (PubMed, Ophthalmic Genet)
The patient was referred for genetic testing and a somatic mosaic mutation was found on the NF1 gene (c.4084C>T on the exon 30) with a variant allele frequency of 20%. This report highlights the role of near infrared reflectance imaging in the incidental finding of choroidal alterations, which led to the diagnosis of NF1 mosaicism.

Patients with hereditary disease are diagnosed at a younger age and develop bilateral tumors more frequently compared to sporadic cases.

Uterine sarcoma with KAT6B/A::KANSL1 fusion: a molecular and clinicopathological study on 9 cases. (PubMed, Virchows Arch)
Of the 8 patients with available follow-up, two died of disease, 3 are currently alive with disease, and 3 have no evidence of disease. The correct recognition of tumors with the KAT6B/A::KANSL1 fusion is essential because despite the bland morphological features of most cases, these tumors have a propensity for aggressive behavior.

Molecular characterization of adult non-glioblastoma central nervous system (CNS) tumors to identify potential targettable alterations (AIOM 2024)
4 pts received TT at recurrence, within clinical trials: one with grade 3 meningioma and ALK rearrangement treated with alectinib, one with PTCH1 mutant medulloblastoma treated with vismodegib, and two with high TMB treated with nivolumab/ipilumumab. The incidence of targettable molecular alterations in adult CNS tumor patients was lower than in GBM. Nevertheless, in a few selected cases TT have the potential to increase treatment options at recurrence and improve outcomes.

Liquid biopsy-based comprehensive genomic profiling captures tumor heterogeneity and identifies cancer vulnerabilities in patients with RAS/BRAFV600E wild type metastatic colorectal cancer in the CAPRI 2-GOIM trial (AIOM 2024)
Materials and The phase II CAPRI 2-GOIM trial investigates the efficacy and safety of biomarkerdriven, cetuximab-based, sequence of three treatment lines in mCRC... Baseline plasma-based comprehensive genomic profiling is feasible with high concordance with tissue-based analysis. Liquid biopsy allows identification of misdiagnosed RAS/BRAF alterations and the ultra-selection of pts, which could benefit from anti-EGFR therapies. Finally, potentially actionable gene alterations were found in half of the pts.

Mesenchymal-type genetic mutations are likely pre-requisite for glioblastoma multiforme to metastasize outside the central nervous system: an original case series and systematic review of the literature. (PubMed, World Neurosurg)
In sum, there is strong evidence that GBMs acquire novel mutations to survive outside the CNS. In some cases, tumor cells likely mutate after seeding scalp tissue during surgery, and in others, they mutate and spread without surgery. Future studies and genetic profiling of primary and metastatic lesions may help uncover the mechanisms of spread.

Cancer risk assessment of premalignant breast tissues from patients with BRCA mutations by genome profiling. (PubMed, NPJ Breast Cancer)
Additional WES on 42 samples with relatively large clone size (VAF > 3%) confirmed that these cell clones harbored multiple mutations (10.7 mutations/sample), and the number of existing mutations was consistent with the clone size (R = 0.50). The results suggest that clonal changes occur in normal breast tissue of women at high risk for breast cancer even before cancer is detected pathologically and/or radiologically, and the clonality score shows the potential to be a valid method of evaluating clonal expansion for cancer-risk assessment that provides appropriate preventive options for patients at high risk for breast cancer.

Cold Atmospheric Plasma Induces Growth Arrest and Apoptosis in Neurofibromatosis Type 1-Associated Peripheral Nerve Sheath Tumor Cells. (PubMed, Biomedicines)
Utilizing established mouse and human cell lines to interrogate the effects of CAP in both in vitro and in vivo settings, we found that NF1-associated PNSTs were highly sensitive to CAP exposure, resulting in cell death. To our knowledge, this is the first application of CAP to NF1-associated PNSTs and provides a unique opportunity to study the complex biology of NF1-associated tumors.

Generation of an induced pluripotent stem cell line from a type 1 neurofibromatosis patient with NF1 mutation. (PubMed, Stem Cell Res)
The iPSC line expresses pluripotency markers, displays a normal karyotype, and is able to differentiate into three germ layers in vitro. This iPSC line represents a valuable cell model for NF1 in humans.
