In December 2013, the U.S. Preventive Services Task Force recommended screening for lung cancer with low-dose computed tomography (LDCT) for selected current and former smokers. The Task Force based the recommendation primarily on the results of the NLST (National Lung Screening Trial). In this trial, patients randomly assigned to LDCT screening for 3 years had lower rates of both lung cancer-specific mortality and all-cause mortality (relative risk reduction, 6.7% [95% CI, 1.2% to 13.6%]; absolute risk reduction, 0.46% [CI, 0% to 0.9%]). Clinicians and health systems confront questions and challenges as they begin to implement lung cancer screening. This paper summarizes a conference during which an internist and a radiologist discuss the application of the Task Force recommendation to an individual patient.

In triple-negative breast cancer (TNBC), pro-tumoral macrophages promote metastasis and suppress the immune response. To target these cells, a previously identified CD206 (mannose receptor)-binding peptide, mUNO was engineered to enhance its affinity and proteolytic stability. The new rationally designed peptide, MACTIDE, includes a trypsin inhibitor loop, from the Sunflower Trypsin Inhibitor-I.

Background: Tracheal, bronchial, and lung cancers (TBL cancers) pose a significant global health challenge, with rising incidence and mortality rates, particularly in China. Studies from the Global Burden of Disease (GBD), 2021, can guide screening and prevention strategies for TBL cancer. This study aims to provide a comprehensive analysis of the burden of TBL cancers in China compared to global data.

Non-small cell lung cancer (NSCLC) frequently metastasizes to the brain, significantly worsened prognoses. This study aimed to develop an interpretable model for predicting survival in NSCLC patients with brain metastases (BM) integrating radiomic features and RNA sequencing data. 292 samples are collected and analyzed utilizing T1/T2 MRIs.

Malignant pleural effusion (MPE) is a common feature in patients with advanced or metastatic malignancies. While significant progress has been made in understanding the biology of pleural effusions, further research is needed to uncover the subsequent behavior of tumor cells following their invasion into the pleural space. This report utilizes flow cytometry to analyze DNA content abnormalities (aneuploidy) and cell cycle status, shedding light on the tumor cell populations present in MPE samples from a patient with lung adenocarcinoma during treatment.
