Upfront Multiplex Gene Test Helps Prolong Survival in Advanced Non-small Cell Lung Cancer.

Background/aim: Detection of genetic abnormalities is crucial for selecting an appropriate therapy to effectively treat advanced non-small cell lung cancer (NSCLC). Multiplex genetic testing aids the selection of appropriate therapy and tailored treatments; however, its impact on survival remains unexplored.

Patients And Methods: Using data from 112 patients with advanced or recurrent NSCLC between February 2020 and April 2023, we investigated the impact of multiplex genetic tests, conducted before the initiation of systemic therapy, on survival.

Prognostic significance of radiological pleuroparenchymal fibroelastosis in complex lung disease: a multicentre retrospective cohort study.

Background: complex (MAC) causes chronic respiratory infectious diseases with diverse clinical features and prognoses. Pleuroparenchymal fibroelastosis (PPFE) is a rare disease characterised by pleural fibrosis with subjacent intra-alveolar fibrosis and alveolar septal elastosis, with unique chest high-resolution CT (HRCT) features (radiological PPFE). An association between recurrent respiratory infections and PPFE formation has been hypothesised; however, the clinical significance of PPFE in MAC lung disease remains unclear.

Effect of Hypoxia on Pulmonary Endothelial Cells from Bleomycin-Induced Pulmonary Fibrosis Model Mice.

Pulmonary fibrosis is a progressive and fatal disorder characterized by dysregulated repair after recurrent injury. Destruction of the lung architecture with excess extracellular matrix deposition induces respiratory failure with hypoxia and progressive dyspnea. The impact of hypoxia on pulmonary endothelial cells during pulmonary fibrogenesis is unclear.

Comparative assessment of NOIR-SS and ddPCR for ctDNA detection of EGFR L858R mutations in advanced L858R-positive lung adenocarcinomas.

Genotyping epidermal growth factor receptor (EGFR) is an essential process to indicate lung adenocarcinoma patients for the most appropriate treatment. Liquid biopsy using circulating tumor DNA (ctDNA) potentially complements the use of tumor tissue biopsy for identifying genotype-specific mutations in cancer cells. We assessed the performance of a high-fidelity sequencing method that uses molecular barcodes called the nonoverlapping integrated read sequencing system (NOIR-SS) for detecting EGFR L858R-mutated alleles in 33 advanced or recurrent patients with L858R mutation-positive lung adenocarcinoma revealed by matched tissue biopsy.

Body composition changes successfully classify prognosis in patients with mycobacterium avium complex lung disease.

Objectives: Loss of body weight, a manifestation of cachexia, is frequently found in patients with Mycobacterium avium complex lung disease (MAC-LD) and known as a prognostic determinant. However, the involvement of body composition changes in the prognosis of patients with MAC-LD remains unclear.

Methods: The cross-sectional-area of the erector spinea muscle (ESM) and mean attenuation of the erector spinae muscles (ESM) in patients with MAC-LD, as determined by computed tomography imaging, were measured in two independent cohorts (137 and 111 patients, respectively).

Clinical impact of minocycline on afatinib-related rash in patients with non-small cell lung cancer harboring epidermal growth factor receptor mutations.

Background: The management of skin toxicity is crucial for efficient afatinib treatment, but the role of tetracycline class antibiotics (TCs) in managing these rashes is relatively unknown.

Methods: We reviewed the clinical records of patients who were administered afatinib for the treatment of non-small cell lung cancer harboring epidermal growth factor receptor mutations between October 2014 and November 2016. Twenty-five patients, who received TCs for the management of afatinib-related skin disorders, were enrolled.

Lupus Pleuritis with Silicotic Nodules in the Parietal Pleura.

A 63-year-old man with occupational exposure to silica presented with cutaneous ulcer, pleuritic pain, and a fever. Laboratory data showed lymphopenia and positive serum antinuclear and anti-DNA antibodies. Computed tomography of the chest showed egg shell-like calcification of the hilar and mediastinal lymph nodes without pulmonary parenchymal involvement of silicosis.

[A CASE OF MILIARY TUBERCULOSIS ORIGINATED FROM CUTANEOUS INFECTION].

An 86-year-old woman with severe dementia had been treated with oral prednisolone at 2 mg/day for autoimmune bullous dermatosis for several years. One year ago, she referred to our hospital due to an ulcerative skin lesion over the right tibial tuberosity. The lesion was treated by an iodine-containing ointment, but did not heal.

Distinctive impact of pre-existing interstitial lung disease on the risk of chemotherapy-related lung injury in patients with lung cancer.

Purpose: Pre-existing interstitial lung disease (pre-ILD) increases the risk of chemotherapy-related lung injury (CRLI). However, whether the risk varies by type of anti-cancer cytotoxic agent in patients with pre-ILD is unknown. In this study, we hypothesized that S-1, an oral fluoropyrimidine agent, is associated with a smaller CRLI risk than docetaxel (DTX) and investigated these agents together with radiological evaluations of pre-ILD via pre-treatment chest computed tomography (CT).
