Clinicopathological characteristics and genetic features of young and senior Ewing sarcoma patients. (PubMed, Diagn Pathol)
Clinicopathological characteristics and genetic features in young and senior EwS patients differed significantly. Targeting cell cycle dysregulation based on age subgroup may be a potential therapeutic strategy for Ewing sarcoma.

Genetic alterations predict poor efficacy, outcomes and resistance to second-line osimertinib treatment in non-small cell lung cancer. (PubMed, Am J Cancer Res)
Additionally, HIST1H2BD represents a novel resistance mutation to osimertinib. All of these findings offer valuable insights for making personalized treatment strategies for NSCLC patients.

Contrasting Effects of Cancer-Associated Mutations in EphA3 and EphB2 Kinases. (PubMed, Biochemistry)
The reciprocal effects of EphB2 and EphA3 on ERK phosphorylation in HEK293T cells were also evident in Ras-GTP loading. Thus, consistent with the dual roles of Eph receptors as tumor promoters and tumor suppressors, somatic mutations have the potential to increase or decrease Eph function, resulting in changes in the downstream signaling transduction.

A BRCA2 germline mutation and high expression of immune checkpoints in a TNBC patient. (PubMed, Cell Death Discov)
Altogether, these findings support an unveiled link between BRCA2 inactivation, HR deficiency and increased expression of immune checkpoints in TNBC. This clinical case highlights the importance of screening TNBC patients for genetic mutations and TMB biomarkers in order to predict the potential efficacy of immunotherapy.

Progressive abdominal pain with acute exacerbation due to retroperitoneal follicular dendritic cell sarcoma: a case report with targeted genomic sequencing analysis. (PubMed, Acta Chir Belg)
The interpretations of CA724, PET/CT, as well as imaging results deserve further investigation in FDCS. Genomic sequencing revealed three novel gene mutations in FDCS, including EPHA3 (nonsense mutation), DDR2 (SNV), and BIRC3 (InDel).

[VIRTUAL] The predictive values of EPHA3 mutations for response to immune checkpoint inhibitors in solid tumors (ESMO 2021)
Our data indicated that EPHA3 mutations were associated with prolonged OS in NSCLC, rather than other cancer types, suggesting that it might act as a predictive biomarker for ICIs therapy in NSCLC. EPHA3 mutations were also correlated with higher TMB and increased activated natural killer cells in NSCLC.
