Eligibility criteria for lung cancer screening increasingly need to consider family history of lung cancer, as well as age and smoking status. Lung cancer screening will reveal a multitude of incidental findings, of variable clinical significance, and with a need for clear pathways of management. Pulmonary nodule sampling is enhanced by intra-procedural imaging and cutting-edge robotic technology.

However, the application value of the mLIPI for patients treated with combination immunotherapy requires further investigation. In this study, we aimed to explore the relationship between the mLIPI and the efficacy of treatment together with the prognosis of patients with advanced non-small cell lung cancer (NSCLC) receiving first-line immune checkpoint inhibitors (ICIs) combined with platinum-based chemotherapy.

Whole lung lavage has been the first-line treatment but recent reports suggest the efficacy of granulocyte-macrophage colony-stimulating factor (GM-CSF). We aimed to review the efficacy and safety of nebulised GM-CSF in aPAP.

Immunotherapy with immune checkpoint inhibitors (ICI) has significantly improved outcomes in some patients, however 80-85% of patients receiving immunotherapy develop primary resistance, manifesting as a lack of response to therapy. Of those that do have an initial response, disease progression may occur due to acquired resistance.

Methods: This study included a whole-genome sequencing cohort (n=11, LxG cohort) and a targeted Oncomine TML panel cohort (n=10, SxD cohort), where paired primary and metastatic samples were obtained by endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA).
Background: Immune checkpoint inhibitors (ICIs) possess remarkable clinical effectiveness in non-small cell lung cancer (NSCLC). Different immune profiles of tumors may play a key role in the efficacy of treatment with ICIs. This article aimed to determine the differential organ responses to ICI in individuals with metastatic NSCLC.

A real-world study with large sample to compare the efficacy and safety of anlotinib plus immune checkpoint inhibitors (ICIs) with ICIs alone in the multiline treatment of advanced non-small cell lung cancer (NSCLC) was urgently needed.
Methods: The data of 535 advanced NSCLC patients were collected from January 1, 2018, to December 31, 2021.

The US Preventive Task Force (USPSTF) has updated screening criteria by expanding age range and reducing smoking history required for eligibility; the International Lung Screen Trial (ILST) data have shown that PLCOM2012 performs better for eligibility than USPSTF criteria. Screening adherence is low (4%-6% of potential eligible candidates in the United States) and depends upon multiple system and patient/candidate-related factors. Smoking cessation in lung cancer improves survival (past prospective trial data, updated meta-analysis data); smoking cessation is an essential component of lung cancer screening.

Recently, outbreaks have been reported in industries involving direct work with high silica-containing materials, such as artificial stone. Here, we describe an unexpected diagnosis made in an asymptomatic 33-year-old female worker employed for 4 years at a quarry for rhyodacite and rhyolite which contain 70% silicon dioxide.

Immune checkpoint inhibitor-related pneumonitis (CIP) was the leading cause of death among ICIs-related adverse events (irAEs). Recurrent episodes of CIP without rechallenge of ICIs were reported in several cases and maybe a unique feature of CIP.

Methods: Retrospective review of a large, prospectively collected database of over 1000 consecutive resections for lung cancer in a quaternary lung cancer centre over a 23-year period.
Background And Objective: Inhalation of high concentrations of respirable crystalline silica (RCS) can lead to silicosis. RCS contains varying levels of iron, which can cause oxidative stress and stimulate ferritin production. This study evaluated iron-related and inflammatory markers in control and silicosis patients.

For PPLs suspicious for lung cancer, current clinical guidelines recommend tissue diagnosis. Radial endobronchial ultrasound (R-EBUS) is a bronchoscopic technique used for this purpose.

Numerous reports describe variations in lung cancer care and outcomes across Australia. There are no data assessing compliance with treatment guidelines and little is known about lung cancer multidisciplinary team (MDT) infrastructure around Australia.

Background: Cyclin D1 (CCND1) is overexpressed in non-small cell lung cancer (NSCLC) and contributes to its tumorigenesis and progression. Accumulating evidence shows that ubiquitin-specific protease 5 (USP5), an important member of the USP family, acts as a tumor promoter by deubiquitinating and stabilizing oncoproteins. However, neither the mechanism for dysregulated turnover of CCND1 protein nor the association of CCND1 with USP5 in NSCLC is well understood.

Pulmonary alveolar proteinosis (PAP) is a rare respiratory syndrome, which can be challenging to diagnose given its non-specific presentation and imaging findings. While most primary cases of PAP have an autoimmune basis, the triggers for the disease are uncertain with occupational factors increasingly thought to be important. We report the unusual complication of pneumomediastinum and bilateral pneumothoraces following endobronchial ultrasound-guided transbronchial needle aspirate in the setting of PAP.

Metastatic lung cancer represents a significant global issue where it is responsible for the most cancer diagnoses and deaths worldwide. Treatment for advanced lung cancer has undergone a series of paradigm shifts from chemotherapy to targeted molecular agents to the most recent immunotherapy strategies. The most successful of the latter involves antibodies that block inhibitory receptors on tumor infiltrating T cells, thereby enhancing T cell activity against tumor cells.
