A Case of Rapid Emergence of Small-cell Carcinoma due to Malignant Transformation or de novo Formation in the Anterior Mediastinum Following Thymoma Resection: The Importance of a Re-biopsy.

A 59-year-old woman presented with multiple mediastinal masses 6 months after post-thymectomy for type B2 thymoma. A diagnosis of small-cell carcinoma (SmCC) via a computed tomography-guided biopsy and fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography revealed no primary lesions outside the anterior mediastinum. The pathologically reevaluated post-thymectomy specimen showed no neuroendocrine differentiation.

A practice-oriented genome-profiling study for acute myeloid leukemia using the novel HANDLE system: HM-screen-JAPAN02.

HM-SCREEN-Japan is a multicenter collaborative project in Japan to evaluate the clinical utility of a cancer genome panel in the treatment of acute myeloid leukemia (AML). The HM-SCREEN-JAPAN02 study used the Amoy Myeloid Panel with the HANDLE system, which enables efficient and rapid sequencing, as the genomic testing kit. The Amoy Myeloid Panel targets 53 genes with established clinical significance or high prevalence.

Gestational exposure to organophosphate ester flame retardants and risk of childhood obesity in the environmental influences on child health outcomes consortium.

Introduction: Organophosphate esters (OPEs) are increasing in use as flame retardants and plasticizers and concerns have been raised given their endocrine-disrupting activities and possible obesogenic consequences. However, longitudinal studies on gestational OPE exposure and childhood obesity are scarce. This study examined whether OPE levels in maternal urine during pregnancy were associated with the risk of childhood obesity.
