Genetic analysis of cervical cancer with lymph node metastasis. (PubMed, J Gynecol Oncol)

The somatic SNV/Indels of EP300 and FBXW7, SBS3 homologous recombination-mediated DNA repair defect were enriched in lymph node-positive patients. For lymph node-positive patients, EP300 or FBXW7 mutations predicted poor prognosis. No matter lymph node-positive or negative, more co-occurring mutation number predicted poor prognosis. PIK3CA mutation may account for the higher TMB and help identify patients who benefit from immunotherapy.

A New t(7; 9)(p12; q34) Involving NOTCH1 and IKZF1 in Pediatric T-Cell Lymphoblastic Lymphoma (ASH 2023)

Summary/perspectivesThis new t(7; 9)(p12; q34) involving ICN1 illustrates the importance to look for ICN1 more extensively in parallel to NOTCH1/FBXW7 mutations in the screening of Notch1 activation pathway in T-ALL/LL specially in the event of a stratification on Notch1 status for treatment. As both NOTCH1 and IKZF1 are major actors of normal T-cell differentiation/proliferation, the oncogenic role of the fusion NOTCH1: : IKZF1 in T-ALL/LL deserves a better understanding in a larger population and will be further explored.

FBXW7-loss sensitizes cells to ATR inhibition through induced mitotic catastrophe. (PubMed, Cancer Res Commun)

ATR-inhibition induces an accelerated S-phase, leading to mitotic catastrophe and cell death caused by the high replication stress present in FBXW7-/- cells. In addition, we provide evidence in cell and organoid studies, and mining of publicly available high throughput drug screening efforts, that this genotype-specific vulnerability extends to multiple types of cancer, providing a rational means of identifying responsive patients for targeted therapy.

In our institutional cohort, we demonstrated that FGFR3::TACC3 fusions are most frequently identified in high-grade gliomas, but can be seen in other tumor types as well.

Genomic signatures and prognosis of advanced stage Chinese pediatric T cell lymphoblastic lymphoma by whole exome sequencing. (PubMed, Front Pediatr)

Although T-ALL and T-LBL both originate from precursor T-cells and are considered different manifestations of the same disease and the outcome of T-LBL is favorable when using T-ALL-based chemotherapy, there are differences in the gene distribution between T-LBL and T-ALL. It seems that the PI3K-Akt signaling pathway and the USP34 gene play important roles in T-LBL, but medicines targeting the USP34 gene or the PI3K-Akt pathway may be invalid.

By transcriptomic analysis, we identify LEF1 signalling as upregulated in Fbxw7/FBXW7-mutant mouse and human endometrial cancers, and in human isogenic cell lines carrying FBXW7 mutation, and validate LEF1 and the additional Wnt pathway effector TCF7L2 as novel FBXW7 substrates. Our study provides new insights into the biology of high-risk endometrial cancer and suggests that targeting LEF1 may be worthy of investigation in this treatment-resistant cancer subgroup.

In this select patient cohort with KRAS G12C mutated mCRC from US academic centers, outcomes, particularly rwPFS, were poor in later lines of therapy. Frontline OS and rwPFS were longer than in other similar studies, which may be attributable to the young median age and high proportion of surgical resection in the metastatic setting observed in this cohort.

Cytogenetic and molecular characteristics and outcomes of adult patients with early T-cell precursor acute lymphoblastic leukemia. (PubMed, Eur J Haematol)

In a subgroup analysis of patients treated with allo-HCT in CR1 (n=29), 5-year OS was 53.8% for ETP-ALL and 55.4% for non-ETP-ALL. Our data showed molecular characteristics of ETP-ALL and non-ETP-ALL and revealed that intensive chemotherapy followed by allo-HCT for post-remission therapy can contribute to preserved survival outcome of adult patients with ETP-ALL.
