    Re-verification and Report Ruling Revision of NTRK Fusion Results of Idylla GeneFusion Assay after Manufacturer Algorithm Update (AMP 2024)
    Our standard operating procedure (SOP) was updated to perform orthogonal confirmation testing for stand-alone equivocal NTRK1/2 and equivocal NTRK3 (5' failure), but to ignore equivocal NTRK3 (5' intact) and report as NTRK2/3 indeterminate. Re-verification showed no change to ALK, ROS1, RET, MET ex14, and NTRK1 results. Sensitivity of NTRK2 detection was significantly increased (80% after orthogonal testing).

    The oncogenic Flip in patients with leptomeningeal metastatic disease (LMD): Longitudinal detection in cerebrospinal fluid tumor cells (CSF-TCs) reveals implications for differential treatment of the LMD tumor (SNO 2024)
    CNSide can be used to detect oncogene amplification on CSF-TCs of patients with LMD, and mutational status of the LMD tumor may differ from the original tumor biopsy. CSF-TC analysis may provide therapeutic insights that vary from the original tumor and could open the door to additional treatment targets for patients struck with LMD.

    Actionable Structural Variant Detection via RNA-NGS and DNA-NGS in Patients With Advanced Non-Small Cell Lung Cancer. (PubMed, JAMA Netw Open)
    Emerging structural variants (eSVs) were found to have a combined prevalence to be 0.7%, with only 47.5% of eSVs detected by DNA-NGS. In this cohort study, the detection of structural variants via concurrent RNA-NGS and DNA-NGS was higher across multiple NCCN-guideline recommended biomarkers compared with DNA-NGS alone, suggesting that RNA-NGS should be routinely implemented in the care of patients with advanced NSCLC.

    Targeted Therapy in Salivary Gland Cancer: Prevalence of a Selected Panel of Actionable Molecular Alterations in a German Tertiary Referral Center Patient Cohort. (PubMed, Mol Diagn Ther)
    Our data indicate that targeted therapy using e.g., trastuzumab deruxtecan, bicalutamide, pembrolizumab, cetuximab, entrectinib or sacituzumab govitecan might be a promising option especially for a relevant subset of patients with RM-SGC not suitable for salvage surgery. However, evidence from clinical studies regarding response rates to these therapies remains sparse, which underlines the need of multicenter clinical trials.

    Clinicopathologic characterization of secretory carcinoma of salivary gland. (PubMed, World J Surg Oncol)
    SCSG is a rare low-grade malignancy with a good prognosis. Pathological and immunohistochemical characteristics are the key to secretory carcinoma (SC) diagnosis, and surgical excision is the major treatment means for SCSG. Whether to perform simultaneous cervical lymph node dissection and other adjuvant therapies should be determined based on the pathological stage and the presence or absence of high-risk factors.

    DNA and RNA Comprehensive Genomic Profiling are Complementary for Detection of Clinically Relevant Fusions in Papillary Thyroid Carcinoma (ATA 2024)
    As demonstrated in our PTC cohort, DNA CGP and RNA CGP may be complementary for fusion detection in certain tumor types. RNA CGP complements DNA CGP by detecting fusions that cannot be efficiently baited on DNA CGP, while DNA CGP may complement RNA CGP by detecting fusions in poor quality (e.g., old archival) samples when RNA sequencing may not be not technically feasible. Clinically relevant fusions detected in this retrospectively profiled PTC cohort included therapeutically targetable fusion events (e.g., RET, NTRK, ALK) and a PAX8::PPARG fusion, which is suggestive of a follicular variant PTC.

    Epithelioid Fibrous Histiocytoma Is on a Continuum With Superficial ALK-rearranged Myxoid Spindle Cell Neoplasm: A Clinicopathologic Series of 35 Cases Including Alternate RET and NTRK3 Fusions. (PubMed, Am J Surg Pathol)
    SAMS is on a morphologic and molecular genetic spectrum with EFH, with a similar body site distribution, frequent clinical presentation as an exophytic skin tumor, and invariably benign outcomes; we conclude that SAMS should be considered a histologic variant of EFH. Some morphologically typical examples harbor alternate RET and NTRK3 fusions, such that SAMS is not an appropriate designation for this morphologic class; instead, to highlight the clinicopathologic similarities to EFH, we propose the diagnostic term "myxoid spindle cell variant of epithelioid fibrous histiocytoma."

    Real-Life Experience with Entrectinib in Neurotrophic Tyrosine Receptor Kinase Fusion-Positive Solid Tumors: A Multicenter Retrospective Trial. (PubMed, Target Oncol)
    In this retrospective study, we aimed to obtain real-world data concerning the use of entrectinib in patients with solid tumors harboring NTRK fusion genes. Although our findings are partially similar to the results of clinical studies, prospective studies in larger patient groups with more diverse tumor types and different demographic characteristics are needed to confirm the findings.

    Secretory Carcinoma of the Thyroid: A Case Report and Update of Literature. (PubMed, Head Neck Pathol)
    Among documented cases of thyroid SC, prognostic factors established for salivary SC have shown broad distributions, including a mitotic activity ranging from < 1 to 10 per 10 high-power fields and variable presence of necrosis, awaiting additional case experience to better elucidate their relevance in thyroid SC. We hereby present a 61-year-old female patient with widely metastatic thyroid SC treated with larotrectinib and provide an updated review of the literature on the molecular pathogenesis and clinicopathologic characteristics of this rare entity.

    IDH 2 - a new gene for personalized therapy in pulmonary adenocarcinomas – reports of two cases (ECP 2024)
    Known under low incidence – mutations require research for 0.4% to 1.1 in pulmonary adenocarcinomas, IDH1/2 inhibitors prescription due to high prevalence of lung carcinoma worldwide. Mutations in IDH1/2 gene may be branching drivers leading to lower subclonality evolution with predictable benefit of IDH1/2 inhibitors.The accumulation of more known cases with IDH1/2 mutations is necessary to elucidate clinicopathological characteristics/clinical evolution after target therapy, in order to reforce the new interpretation of malignant tumours postponed survival through conversion of cell cycle.

    The oncogenic fusion protein EML4-NTRK3 requires three salt bridges for stability and biological activity. (PubMed, Heliyon)
    We also demonstrate that EML4-NTRK3 is localized in the cytoplasm and fails to associate with microtubules. These data suggest potential therapeutic strategies for Infantile Fibrosarcoma cases bearing EML4-NTRK3 fusion through inhibition of salt bridge interactions and disruption of multimerization.
