Clonal hematopoiesis of indeterminate potential (CHIP) is associated with increased mortality and malignancy risk, yet the determinants of clonal expansion remain poorly understood. We performed sequencing at >4,000x depth of coverage for CHIP mutations in 6,986 postmenopausal women from the Women's Health Initiative at two timepoints approximately 15 years apart. Among 3,685 mutations detected at baseline (VAF ≥ 0.

Background: The differential diagnosis between adult systemic EBV-positive T-cell lymphoproliferative disorders (EBV T-LPD) and angioimmunoblastic T-cell lymphoma (AITL) with multiple EBV infections is difficult, and distinguishing between the two has become a diagnostic challenge for pathologists. Given that the clinical treatment plans are different, an accurate diagnosis is a prerequisite to ensure effective treatment, therefore, it is extremely necessary and meaningful to find effective pathological indicators for distinguishing between two diseases.
Methods: We present a retrospective study comparing 7 cases of adult EBV T-LPD and 16 cases of AITL with multiple EBV infections diagnosed at our institution from 2017 to 2022.
Dynamic characterization of circulating tumor DNA in HER2-altered advanced non-small cell lung cancer treated with pyrotinib and apatinib: Exploratory biomarker analysis from PATHER2 study.

Background: HER2 mutations are critical drivers of non-small cell lung cancer (NSCLC), affecting 2 %-3 % of patients and often leads to poor prognosis and limited response to conventional therapies. This study investigates the genomic characteristics and prognostic relevance of dynamic circulating tumor DNA (ctDNA) monitoring in advanced NSCLC patients with HER2 mutations treated with pyrotinib and apatinib.
Methods: The PATHER2 study included 33 advanced NSCLC patients harboring HER2 mutations or amplification, who received combination therapy of pyrotinib and apatinib.
Evaluation of plasma cell sorting methods in multiple myeloma patients: flow cytometry versus magnetic beads.

Background: The prognosis of a plasma cell neoplasm (PCN) varies depending on the presence of genetic abnormalities. However, detecting sensitive genetic mutations poses challenges due to the heterogeneous nature of the cell population in bone marrow aspiration. The established gold standard for cell sorting is fluorescence-activated cell sorting (FACS), which is associated with lengthy processing times, substantial cell quantities, and expensive equipment.

Patients present as anemia, infection, bleeding, and tissue and organ infiltration. MICM classification makes the classification of AML more accurate and lays a foundation for the correct treatment and prognosis of AML.
