Aim: To provide a further insight into the usefulness of lung biopsy in children.
Methods: Lung biopsies in children from January 2007 to December 2017 were reviewed (n=39). The histology results were categorised as: definitive diagnosis, normal lung parenchyma, inconclusive.
Results: Lung biopsy provided a definitive diagnosis in 25 (64%) cases. A suspected diagnosis was confirmed in 16 (41%) and a new diagnosis was found in 9 (23%) children. Histology was inconclusive in 11 (28%) cases and normal in 3 (8%). Fifteen (38%) children had treatment altered due to the biopsy result.
Conclusion: Lung biopsy mostly confirmed the suspected diagnosis and was associated with a low procedure related morbidity (n=1) and mortality (n=0). Importantly, the biopsy result identified a pathology which altered treatment in over one third of patients. However, in a number of cases the histology was inconclusive, therefore careful patient selection is recommended to maximise diagnostic yield.

Aim: Tumour-infiltrating lymphocytes (TILs) represent a promising cancer biomarker. Different TILs, including CD8+, CD4+, CD3+, and FOXP3+, have been associated with clinical outcomes. However, data are lacking regarding the value of TILs for patients receiving radiation therapy (RT).

Rationale: ROS proto-oncogene 1 (ROS1) fusion is a rare but important driver mutation in non-small cell lung cancer, which usually shows significant sensitivity to small molecule tyrosine kinase inhibitors. With the widespread application of next-generation sequencing (NGS), more fusions and co-mutations of ROS1 have been discovered. Non-muscle myosin heavy chain 9 (MYH9) is a rare fusion partner of ROS1 gene as reported.

Purpose: Adaptive radiotherapy accounts for interfractional anatomic changes. We hypothesize that changes in the gross tumor volumes identified during daily scans could be analyzed using delta-radiomics to predict disease progression events. We evaluated whether an auxiliary data set could improve prediction performance.

Deployment-related constrictive bronchiolitis (DRCB) has emerged as a health concern in military personnel returning from Southwest Asia. Exposure to smoke from a fire at the Al-Mishraq sulfur enrichment facility and/or burn pits was reported by a subset of Veterans diagnosed with this disorder. DRCB is characterized by thickening and fibrosis of small airways (SA) in the lung, but whether these are related to toxin inhalation remains uncertain.

Clear cell renal cell carcinoma (KIRC) is the most prevalent subtype of renal cell carcinoma (RCC), accounting for 70% to 80% of all RCC cases. The CRYAB (αB-crystallin) gene is broadly expressed across various human tissues, yet its role in KIRC progression remains unclear. This study aims to elucidate the function of CRYAB in KIRC progression and to assess its potential as a biomarker for early diagnosis, therapeutic targeting, and prognosis.
