Management of Low-Grade Gliomas.
Cancer J
January 2025
From the Division of Neuro-Oncology, Department of Neurology and the Herbert Irving Comprehensive Cancer Center, Columbia University Vagelos College of Physicians & Surgeons and NewYork-Presbyterian, New York, NY.
The term "low-grade glioma" historically refers to adult diffuse gliomas that exhibit a less aggressive course than the more common high-grade gliomas. In the current molecular era, "low-grade" refers to World Health Organization central nervous system grade 2 gliomas almost always with an isocitrate dehydrogenase (IDH) mutation (astrocytomas and oligodendrogliomas). The term "lower-grade gliomas" has emerged encompassing grades 2 and 3 IDH-mutant astrocytomas and oligodendrogliomas, to acknowledge that histological grade is not as important a prognostic factor as molecular features, and distinguishing them from grade 4 glioblastomas, which lack an IDH mutation.

Expert Rev Respir Med
January 2025
Division of Pulmonary & Critical Care Medicine, Mayo Clinic, Rochester MN, USA.
Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Material And Methods: The demographic, radiologic, prognostic, and treatment data of patients diagnosed with grade 4 diffuse glioma between 2016 and 2019 were reviewed and recorded. Tim-3 and Rel-B were applied to the paraffin-embedded tissues by immunohistochemistry method.
Primary cardiac lymphoma: a clinicopathological study of 121 cases.
Front Oncol
January 2025
Department of Hematology, Linyi People's Hospital, Linyi, Shandong, China.
Background: Primary cardiac lymphoma (PCL) is an exceedingly uncommon type of lymphoma that primarily affects the heart and/or pericardium, or manifests through cardiac symptoms due to myocardial infiltration. The infrequency of PCL, coupled with its non-specific clinical presentations, often complicates early diagnosis. This study aims to fill the existing gap in clinical knowledge regarding PCL by detailing a case of PCL and examining its clinical features, auxiliary examinations, treatment approaches, and prognostic outcomes, thereby facilitating early detection and enhancing patient care.

Quant Imaging Med Surg
January 2025
Department of Magnetic Resonance Imaging Diagnostic, The Second Affiliated Hospital of Harbin Medical University, Harbin, China.
Background: Lymphovascular invasion (LVI) is an independent prognostic factor for patients with rectal cancer (RC). Recent studies have shown that deep learning (DL)-based magnetic resonance imaging (MRI) has potential in evaluating the treatment response of RC patients, but the role of MRI-based DL in assessing RC LVI remains unclear. This study sought to develop and validate a DL model to evaluate the LVI status of RC patients preoperatively based on MRI, and to test its performance at an external center.
