Objective: To update the epidemic curves for lung cancer in the United States by gender in relation to the temporal trends in adult current cigarette smoking prevalence.
Methods: The design of the study was ecologic, based on population figures. Available data on the prevalence of current cigarette smoking from 1920 to 1990 were plotted in conjunction with age-adjusted lung cancer mortality rates from 1930 to 1992 for each sex.
Results: There was a strong temporal relationship between the curves for cigarette smoking prevalence and lung cancer mortality rate with approximately a 30-year population latency period in both men and women. The curves occurred later in women than in men. The lung cancer rate in men peaked in 1990 and then began to decline while the rate in women continued to rise.
Conclusions: The temporal association between cigarette smoking prevalence and lung cancer mortality provides additional support for the causal relationship between smoking and lung cancer.

Background: Manual extraction of real-world clinical data for research can be time-consuming and prone to error. We assessed the feasibility of using natural language processing (NLP), an AI technique, to automate data extraction for patients with advanced lung cancer (aLC). We assessed the external validity of our NLP-extracted data by comparing our findings to those reported in the literature.

Objectives: The lack of definitive biomarkers presents a significant challenge for chemo-immunotherapy in extensive-stage small-cell lung cancer (ES-SCLC). We aimed to identify key genes associated with chemo-immunotherapy efficacy in ES-SCLC through comprehensive gene expression analysis using machine learning (ML).
Methods: A prospective multicenter cohort of patients with ES-SCLC who received first-line chemo-immunotherapy was analyzed.

A 53-year-old woman was found to have a soft tissue mass in the right lower lung lobe on chest CT, raising suspicion of lung cancer. For staging, 18F-FDG PET/CT was performed, which demonstrated intense tracer uptake in the mass (SUVmax, 14.6).

This work established the cytotoxic, antioxidant and anticancer effects of copper nanoparticles (CuNPs) manufactured with fennel extract, especially on non-small cell lung cancer (NSCLC) as well. CuNPs caused cytotoxicity in a dose-dependent manner for two NSCLC cell lines, A549 and H1650. At 100 μg/ml, CuNPs reduced cell viability to 70% in A549 cells and 65% in H1650 cells.
