    Genetic and Immunohistochemical Profiling of Malignant Mesothelioma With Brain Metastasis: A Report of Two Cases. (PubMed, Cancer Rep (Hoboken))
    To our knowledge, this represents the first reported genetic profiling of MM with BM. The TP53 frameshift mutation is unusual for MM, and its potential association with rapid disease progression warrants further investigation. Given the aggressive nature of MM, SRS may be preferable to WBRT due to its shorter treatment time and ease of combination with systemic regimens.

    Pancreatic Adenocarcinoma Associated With a Germline RAD51C Mutation. (PubMed, ACG Case Rep J)
    RAD51C plays a critical role in homologous recombination DNA repair, and its loss may confer sensitivity to platinum-based chemotherapy and poly (ADP-ribose) polymerase inhibitors. This case represents only the second reported RAD51C-associated PDAC and reinforces the importance of universal germline testing to identify hereditary risk and guide therapeutic strategies.

    Immuno-molecular features associated with exceptional recurrence-free survivorship from Ovarian Cancer in the pre-PARP era. (PubMed, NPJ Genom Med)
    Overall, exceptional survival in HGSOC is associated with younger age, enrichment of BRCA2 mutations and BRCA1/RAD51C methylation, reduced CCNE1 amplification, and a competent antitumor immune response. These findings highlight potential biomarkers for refining risk stratification and guiding personalized therapeutic strategies in ovarian cancer management.
