Neurofibromatosis type 1 (NF1) and neurofibromatosis type 2 (NF2) are autosomal dominant inherited neurocutaneous disorders or phakomatoses secondary to mutations in the and tumor suppressor genes, respectively. Although they share a common name, NF1 and NF2 are distinct disorders with a wide range of multisystem manifestations that include benign and malignant tumors. Imaging plays an essential role in diagnosis, surveillance, and management of individuals with NF1 and NF2. Read More

Heavy-Ion-Induced Lung Tumors: Dose- & LET-Dependence.

Life (Basel) 2022 Jun 17;12(6). Epub 2022 Jun 17.

Biological Systems & Engineering Division, Lawrence Berkeley Laboratory, Berkeley, CA 94720, USA.

There is a limited published literature reporting dose-dependent data for in vivo tumorigenesis prevalence in different organs of various rodent models after exposure to low, single doses of charged particle beams. The goal of this study is to reduce uncertainties in estimating particle-radiation-induced risk of lung tumorigenesis for manned travel into deep space by improving our understanding of the high-LET-dependent dose-response from exposure to individual ion beams after low particle doses (0.03-0.

J Biomed Nanotechnol 2022 Mar;18(3):705-717

Department of Oncology, Zhongda Hospital, Medical School, Southeast University, Nanjing, 210009, P. R. China.

Identification of malignancy from sub-centimeter lung nodules (LNs, <1 cm) is core for prevention and treatment of primary phases of lung cancer (LC). The study's purpose was to predict micro-nodular lung cancer (mnLC), such as adenocarcinoma (AIS), micro-invasive adenocarcinoma (MIA), and invasive adenocarcinoma stage 1 (IA) based on serum extracellular nano-vesicles (sEVs) miR-153-3p. sEVs-miR-153-3p was selected in this study and then used to investigate the expression and efficacy by RT-qPCR in the validation phase, followed by sEVs derived from patients of mnLC, benign lung nodule (BLN), and healthy people groups comprised of 135 recruiters.

Pearls and Pitfalls in Lung Cancer CT Screening.

Semin Ultrasound CT MR 2022 Jun 12;43(3):246-256. Epub 2022 Mar 12.

Department of Thoracic Imaging, The University of Texas MD Anderson Cancer Center, Houston, TX.

Annual LDCT lung cancer screening is recommended by the United States Preventive Services Task Force (USPSTF) for high-risk population based on the results from the National Lung Cancer Screening Trial (NLST) that showed a significant (20%) reduction in lung cancer-specific mortality rate with the use of annual low-dose computed tomography (LDCT) screening. More recently, the benefits of lung cancer screening were confirmed by the Dutch- Belgian NELSON trial in Europe. With the implementation of lung screening in large scale, knowledge of the limitations related to false positive, false negative and other potential pitfalls is essential to avoid misdiagnosis.

Pulmonary Nodule Clinical Trial Data Collection and Intelligent Differential Diagnosis for Medical Internet of Things.

Contrast Media Mol Imaging 2022 26;2022:2058284. Epub 2022 May 26.

Department of Cardiothoracic Surgery, The Second Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang 325000, China.

In this paper, the medical Internet of things (IoT) is used to pool data from clinical trials of pulmonary nodules, and on this basis, intelligent differential diagnosis techniques are investigated. A filtered orthogonal frequency division multiplexing model based on polarisation coding is proposed, where the input data are fed to a modulator after polarisation cascade coding, and the system performance is analysed under a medical Internet of things modulated additive Gaussian white noise channel. The above polarisation-coded filtered orthogonal frequency division multiplexing system components are applied to electroencephalogram (EEG) signal transmission, to which a threshold compression module and a vector reconstruction module are added to address the system power burden associated with the acquisition and transmission of large amounts of real-time EEG data in the medical IoT.

ROS1-positive Inflammatory Myofibroblastic Tumor of the Small Bowel Causing Obstruction: A Case Report.

J Radiol Case Rep 2022 Jan 1;16(1):14-21. Epub 2022 Jan 1.

The Institute of Pathology, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.

Inflammatory Myofibroblastic Tumors (IMTs) are rare fibroblastic/myofibroblastic neoplasms that affect predominately pediatric patients and young adults. Almost half of the patients with IMTs have a chromosomal abnormality in the Anaplastic Lymphoma Kinase 1 gene on chromosome 2p23. Although these tumors occur primarily in the lung, lesions have been reported in a variety of intra-abdominal organs like the liver, spleen, and mesentery. Read More

Soluble HLA peptidome of pleural effusions is a valuable source for tumor antigens.

J Immunother Cancer 2022 05;10(5)

Institute of Pulmonary Medicine, Chaim Sheba Medical Center, Ramat Gan, Israel

Background: Soluble human leucocyte antigen (sHLA) molecules, released into the plasma, carry their original peptide cargo and provide insight into the protein synthesis and degradation schemes of their source cells and tissues. Other body fluids, such as pleural effusions, may also contain sHLA-peptide complexes, and can potentially serve as a source of tumor antigens since these fluids are drained from the tumor microenvironment. We explored this possibility by developing a methodology for purifying and analyzing large pleural effusion sHLA class I peptidomes of patients with malignancies or benign diseases. Read More

Primary Mediastinal Large B-Cell Lymphoma Achieved by Non-Cautery Assisted Transbronchial Mediastinal Cryobiopsy.

Respiration 2022 May 16:1-5. Epub 2022 May 16.

Department of Respiratory Disease, Xinqiao Hospital, Third Military Medical University, Chongqing, China.

Transbronchial mediastinal cryobiopsy is a novel sampling strategy that shows improved diagnostic utility for mediastinal lesions, particularly in rare tumors and benign disorders, as compared to standard endobronchial ultrasound-guided transbronchial needle aspiration. During this procedure, electrocautery incision is frequently needed to advance the cryoprobe through the airway into the mediastinal lesion, which however results in increased operative difficulty and prolonged procedural time. Here we present a case of mediastinal large B-cell lymphoma successfully diagnosed by transbronchial mediastinal cryobiopsy without cautery-induced airway incision. Read More

Endobronchial lipoma.

Autops Case Rep 2022 2;12:e2021377. Epub 2022 May 2.

Augusta University, Medical College of Georgia, Augusta, Georgia, USA.

Endobronchial lipomas are rare benign lung tumors that can cause bronchial obstruction and parenchymal damage. While an uncommon etiology, they are often misdiagnosed due to a clinical presentation similar to obstructive pulmonary pathologies such as COPD and asthma. Upon review of English-language literature, under 50 cases of endobronchial lipomas were documented in the prior 10 years (2011-2021). Read More
