Efficacy of Immune Checkpoint Inhibitor With or Without Chemotherapy for Nonsquamous NSCLC With Malignant Pleural Effusion: A Retrospective Multicenter Cohort Study.

Introduction: Malignant pleural effusion (MPE) is associated with poor treatment outcome in patients with NSCLC receiving immune checkpoint inhibitors (ICIs). ICIs and chemotherapy (ICI/Chemo) combination therapy is currently the standard therapy for NSCLC, and some ICI/Chemo regimens for nonsquamous (non-Sq) NSCLC contain bevacizumab (BEV), which is effective for controlling MPE and may enhance immune response. This study aimed to determine the optimal first-line treatment for this clinical population.

Bronchial ethanol injection therapy for airway obstruction in lung cancer patients.

Obstructive endobronchial tumours often cause decreased quality of life. Bronchial ethanol injection (BEI) therapy is considered an effective modality for airway dilatation or haemoptysis without specialist equipment. Here, we report experiences of two cases in which BEI therapy was effective for obstructive endobronchial tumours.

Expectoration of tonsillar metastasis of pulmonary pleomorphic carcinoma after pseudoprogression: A case report.

Pulmonary pleomorphic carcinoma is a rare malignant tumor that grows rapidly and has a poor prognosis. Although no effective treatments have so far been established, immune checkpoint inhibitors (ICIs) have shown clinical improvement in some cases of pleomorphic carcinoma. However, pseudoprogression is a major concern for treatment of this carcinoma using ICIs.

Pleuroparenchymal fibroelastosis in complex pulmonary disease: clinical characteristics and prognostic impact.

The association between complex pulmonary disease (MAC-PD) and pleuroparenchymal fibroelastosis (PPFE) has been reported previously, and interstitial pneumonia as a comorbidity is associated with a worse prognosis. However, no study has thoroughly reported on PPFE associated with MAC-PD. The present study investigated the prevalence, clinical characteristics, and prognostic impact of PPFE in patients with MAC-PD.

Oscillometry and computed tomography findings in patients with idiopathic pulmonary fibrosis.

Although the utility of oscillometry for predicting disease severity in idiopathic pulmonary fibrosis (IPF) had been researched, little has been reported on the mechanism of why respiratory impedance reflects disease severity. In addition, traction bronchiectasis has been considered to reduce respiratory resistance and correlate negatively with airflow obstruction, but this hypothesis has not been validated. The present study aimed to investigate the correlations between oscillometric parameters and fibrosis-related lung abnormalities in IPF and to assess the utility of oscillometry as a surrogate marker for traction bronchiectasis and airflow obstruction.

Safety and effectiveness of pirfenidone combined with carboplatin-based chemotherapy in patients with idiopathic pulmonary fibrosis and non-small cell lung cancer: A retrospective cohort study.

Background: Pirfenidone is an antifibrotic agent that is potentially effective for the treatment of idiopathic pulmonary fibrosis (IPF). However, no study has reported on its prophylactic value against chemotherapy-associated acute IPF exacerbations when combined with chemotherapy for non-small cell lung cancer (NSCLC). The present study assessed the safety and effectiveness of pirfenidone combined with carboplatin-based chemotherapy or immune checkpoint inhibitors (ICIs) in patients with IPF and NSCLC.

Radiographic change over 11 years in a patient with asbestos-related pleural disease.

Asbestos-related pulmonary conditions such as benign asbestos pleural effusion (BAPE) and diffuse pleural thickening (DPT) can develop after many years of asbestos exposure. These conditions cause progressing constrictive deficit in pulmonary function which may lead to respiratory failure and death. We report the case of a 72-year-old man with asbestos-related BAPE and DPT which developed approximately 40 years after occupational asbestos exposure, leading to chronic respiratory failure and death.

Anti-proteinase 3-positive Eosinophilic Granulomatosis with Polyangiitis Revealed by Cardiac Tamponade.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis characterized by asthma, eosinophilia, and diffuse eosinophilic infiltration. Although cardiovascular involvement is common and a leading cause of EGPA-related mortality, severe pericarditis-led cardiac tamponade occurs rarely. We herein report a 72-year-old man with anti-proteinase 3 (anti-PR3) anti-neutrophil cytoplasmic antibody (ANCA)-positive EGPA diagnosed by the presence of cardiac tamponade, which responded quickly to pericardiocentesis and a single administration of prednisolone.
