Background: Lung adenocarcinoma (LUAD) is a sub-type of non-small cell lung cancer (NSCLC) that is often associated with genetic alterations, including the Kirsten rat sarcoma viral oncogene homolog () mutation. The mutation is particularly challenging to treat due to resistance to targeted therapies. This study aims to develop a predictive model for the mutation in patients with LUAD by integrating clinical, dual-energy spectral computed tomography (DESCT), and radiomics features.

Construction of a neutrophil extracellular trap formation-related gene model for predicting the survival of lung adenocarcinoma patients and their response to immunotherapy.

Transl Lung Cancer Res

December 2024

Department of Clinical Laboratory, State Key Laboratory of Molecular Oncology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: Lung adenocarcinoma (LUAD) is associated with high morbidity and mortality rates. Increasing evidence indicates that neutrophil extracellular traps (NETs) play a critical role in tumor progression, metastasis and immunosuppression in the LUAD tumor microenvironment (TME). Nevertheless, the use of NET formation-related genes (NFRGs) to predict LUAD patient survival and response to immunotherapy has not been explored.

Machine learning-based radiomics for guiding lymph node dissection in clinical stage I lung adenocarcinoma: a multicenter retrospective study.

Transl Lung Cancer Res

December 2024

Department of Thoracic Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: Preoperative assessment of lymph node status is critical in managing lung cancer, as it directly impacts the surgical approach and treatment planning. However, in clinical stage I lung adenocarcinoma (LUAD), determining lymph node metastasis (LNM) is often challenging due to the limited sensitivity of conventional imaging modalities, such as computed tomography (CT) and positron emission tomography/CT (PET/CT). This study aimed to establish an effective radiomics prediction model using multicenter data for early assessment of LNM risk in patients with clinical stage I LUAD.

Background: Thoracic radiotherapy (TRT) has shown potential benefits in improving local control and overall survival (OS) in chemotherapy-responsive small-cell lung cancer (SCLC) cases. However, its role in the era of chemoimmunotherapy remains underexplored. In the current era of immunotherapy, this study evaluated the efficacy and safety of consolidative TRT (cTRT) in patients with extensive-stage SCLC (ES-SCLC) and assessed its impact on OS.

Validation of T stage classification strategy for >2 cm ground-glass opacity non-small cell lung cancer: a retrospective cohort study.

Transl Lung Cancer Res

December 2024

Department of Thoracic Surgery and Institute of Thoracic Oncology, West China Hospital, Sichuan University, Chengdu, China.

Background: The Lung Cancer Staging Program of the International Association for the Study of Lung Cancer (IASLC) has proposed using solid component size, rather than overall tumor size, for T-staging. However, studies focusing on patients with ground-glass opacity (GGO) lesions with a diameter larger than 2 cm are limited. This study aims to validate the T stage classification strategy recommended by IASLC in this specific and less-studied patient group.

Background: Small-cell lung cancer (SCLC) is highly malignant. Despite being highly sensitive to initial chemotherapy and radiotherapy, the recurrence rate is high. Atezolizumab is the first immune checkpoint inhibitor (ICI) that has been proven to provide an overall survival (OS) benefit for extensive-stage SCLC (ES-SCLC), making ICIs in combination with chemotherapy the standard first-line treatment for ES-SCLC.

December 2024

Department of Pathology, Tianjin Medical University Cancer Institute and Hospital, National Clinical Research Center for Cancer, Tianjin's Clinical Research Center for Cancer, Key Laboratory of Cancer Prevention and Therapy, Tianjin, China.

Background: Differences in the immune microenvironment and responses to immunotherapy may exist between primary non-small cell lung cancer (NSCLC) and brain metastases (BMs). This study aimed to investigate discrepancies in programmed death-ligand 1 (PD-L1) expression, tumor-infiltrating lymphocytes (TILs), tertiary lymphoid structures (TLS), and tumor mutational burden (TMB) between matched BMs and primary tumors (PTs) in NSCLC.

Methods: Twenty-six pairs of surgically resected BMs and corresponding PTs from NSCLC patients were collected.

Background: Spread through air spaces (STAS) in lung adenocarcinoma (LUAD) is a distinct pattern of intrapulmonary metastasis where tumor cells disseminate within the pulmonary parenchyma beyond the primary tumor margins. This phenomenon was officially included in the World Health Organization (WHO)'s classification of lung tumors in 2015. STAS is characterized by the spread of tumor cells in three forms: single cells, micropapillary clusters, and solid nests.

Background: The combination therapy of the B-Raf proto-oncogene (BRAF) inhibitor dabrafenib and the mitogen-activated protein kinase kinase (MEK) inhibitor Trametinib has shown favorable outcomes in patients initially identified with BRAF mutations. However, there are currently no large-scale study data focusing on the use of a triple therapy regimen of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) plus dabrafenib and trametinib in patients with newly concomitant BRAF mutations after acquiring resistance to EGFR-TKIs. Our study aimed to explore the efficacy and safety of the triple therapy regimen through a multi-center real-world experience.

Background And Objective: As the most common cancer to progress to brain metastases (BMs), lung cancer presents with intracranial involvement in approximately 20% of patients at the time of diagnosis and lung cancer BMs constitute approximately half of all BMs. The current clinical strategy for managing lung cancer BMs involves a combination of systemic anticancer therapies with local radiation or surgical interventions. The efficacy of systemic treatments is often constrained by the blood-brain barrier (BBB) and the poor inhibition effect of the drug itself.

Oxidative potential (OP) is increasingly recognized as a more health-relevant metric than particulate matter (PM) mass concentration because of its response to varying chemical compositions. Given the limited research on the OP of complex combustion aerosols, the effects of aging processes on their OP remain underexplored. We used online instruments to track the evolution of OP [via dithiothreitol (DTT) assays] during the aging of wood burning and coal combustion emissions by hydroxyl-radical-driven photooxidation and dark ozonolysis.

Nanofiltration Membranes for Efficient Lithium Extraction from Salt-Lake Brine: A Critical Review.

ACS Environ Au

January 2025

Dow Centre for Sustainable Engineering Innovation, School of Chemical Engineering, The University of Queensland, Brisbane, QLD 4072, Australia.

The global transition to clean energy technologies has escalated the demand for lithium (Li), a critical component in rechargeable Li-ion batteries, highlighting the urgent need for efficient and sustainable Li extraction methods. Nanofiltration (NF)-based separations have emerged as a promising solution, offering selective separation capabilities that could advance resource extraction and recovery. However, an NF-based lithium extraction process differs significantly from conventional water treatment, necessitating a paradigm shift in membrane materials design, performance evaluation metrics, and process optimization.

Brown carbon (BrC) has been recognized as an important light-absorbing carbonaceous aerosol, yet understanding of its influence on regional climate and air quality has been lacking, mainly due to the ignorance of regional coupled meteorology-chemistry models. Besides, assumptions about its emissions in previous explorations might cause large uncertainties in estimates. Here, we implemented a BrC module into the WRF-Chem model that considers source-dependent absorption and avoids uncertainties caused by assumptions about emission intensities.

Hibernation is a crucial aspect of the life history of freshwater turtles inhabiting temperate regions. Therefore, understanding their hibernation habitat selection is essential for the targeted conservation of turtle species and their habitats. The Chinese softshell turtle (), a medium-sized freshwater turtle, is widely distributed in China; however, populations are rapidly declining, and threatened by habitat destruction, overfishing, and water pollution.
