Article Abstract
Primary pulmonary sarcoma is a rare disease and is much less common than lung cancer among tumors arising from pulmonary cysts. We report the case of a female patient who showed multifocal cysts in the left S9-10. Follow-up computed tomography (CT) revealed that the cyst tended to regress, but the solid component of the cyst wall continued to thicken, growing to a 10-cm-diameter tumor. Thoracoscopic left lower lobectomy was performed to diagnose and treat the cystic lung lesions. For the pathology of the pulmonary cystic lesion, it was marked by solid tumors composed of proliferative atypical spindle cells, with some trapped bronchial tissue. Based on the imaging and pathological findings, the diagnosis was primary pulmonary sarcoma arising from the pulmonary cyst. The present case highlights that, even when a pulmonary cyst appears to shrink, careful follow-up and timely surgical consideration are warranted if cyst wall thickening is observed.

Chronic kidney disease and incident cancer risk: an individual participant data meta-analysis.
Br J Cancer
September 2025
School of Cardiovascular and Metabolic Health, University of Glasgow, Glasgow, UK.
Background: Studies examining the association of chronic kidney disease (CKD) with cancer risk have demonstrated conflicting results.
Methods: This was an individual participant data meta-analysis including 54 international cohorts contributing to the CKD Prognosis Consortium. Included cohorts had data on albuminuria [urine albumin-to-creatinine ratio (ACR)], estimated glomerular filtration rate (eGFR), overall and site-specific cancer incidence, and established risk factors for cancer.

Glucose restriction generally limits tumor growth. Recently, Wu et al. reported that glucose restriction inhibits primary tumors but promotes lung metastasis by forming a macrophage-dominated, natural killer (NK) cell-deficient pre-metastatic niche (PMN).

Background: Protein lactylation has been implicated in stress-responsive cellular mechanisms, yet its role in lung transplantation-associated ischemia-reperfusion injury (IRI) remains undefined.
Methods: Transcriptomic profiles from GSE145989 were analyzed through differential expression analysis (limma) and weighted gene co-expression network analysis (WGCNA). Integrating the identified genes with lactylation-related signatures uncovered key lactylation-related genes (LRGs) as potential targets.
Air pollution and long COVID: association with pulmonary function and radiological abnormalities 3-15 months post-COVID.

While studies have examined associations between air pollution and subjective long COVID outcomes such as fatigue and symptoms, no studies have focused on objective lung health measures. This study aimed to assess the impact of air pollution, examined through different exposure methods (exposures assigned via geospatial model, versus residential and personal measurements) on pulmonary function and radiological abnormalities in long COVID patients. We recruited 95 patients who attended a hospital outpatient clinic 3-6 months post-infection, during which pulmonary function was assessed via spirometry (FEV1,FVC,FEV1/FVC ratio) and diffusion capacity for carbon monoxide (DLCO), along with a chest CT.
