    Altered TP53, CDKN2A, ATM, EPHA7, POT1, CHEK1, GRIN2A, and EGFR Predict Shorter Survival in Penile Squamous Cell Carcinoma. (PubMed, Mod Pathol)
    We detected 160 alterations with potential treatment implications, with 21.2% of samples showing alterations in the homologous recombination pathway. To the best of our knowledge, this study describes the largest cohort of pSCC with complex molecular-pathological, clinical, and prognostic analysis correlating with prognosis.

    Response to Carboplatin and Paclitaxel in the treatment of hereditary breast ovarian cancer syndrome (HBOC): a case report. (PubMed, J Pak Med Assoc)
    This dynamic treatment not only led to nearly complete remission of high-grade ovarian serous cancer but also triggered regression in grade-2 invasive ductal breast cancer after just a few rounds of chemotherapy. Consequently, what started as palliative care evolved into a curative triumph.

    Identifying Novel Germline Mutations and Copy Number Variations in Patients With SCLC. (PubMed, JTO Clin Res Rep)
    Patients with SCLC with the seven pathogenic alterations were observed to have a numerically longer overall survival (hazard ratio = 0.50) and progression-free survival (hazard ratio = 0.45) though not statistically significant compared with the remaining cohort. Our study identifies novel germline alterations, including a CNV, and provides additional evidence that germline factors could be important contributing factors to the development of SCLC.

    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.

    Histologic patterns in prostatic adenocarcinoma are not predictive of mutations in the homologous recombination repair pathway. (PubMed, Hum Pathol)
    Tumors with >20  % or >30  % histologic patterns by volume also demonstrated no significant association with mutational status. This study suggests that histopathologic examination alone is insufficient to distinguish prostate cancer with germline or somatic mutations in HRR pathway genes, highlighting the continuing importance of ancillary molecular diagnostics in guiding therapy selection for prostate cancer patients who may benefit from PARP inhibitors.

    Real-world homologous recombination repair mutation (HRRm) testing patterns in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with olaparib in the United States. (ASCO-GU 2024)
    Pts with confirmed mCRPC diagnosis, age ≥21 years, treated with olaparib monotherapy after exposure to abiraterone or enzalutamide, and with positive HRRm status were included. This real-world analysis highlights the need for earlier HRRm testing in pts with mCRPC to allow for optimal timing of novel treatment options that have shown efficacy in a biomarker-selected population. Most pts in this study were tested and diagnosed with HRRm many months after mCRPC diagnosis, at which point they had high levels of bone metastasis, multiple sites of distant metastases, and opioid use at the initiation of olaparib treatment. HRR testing in pts before or at the time of mCRPC would allow for olaparib therapy earlier in the disease course.
