The paper summarizes the results of examination of 100 patients with malignant tumors of the lung. The results of X-ray study, linear tomography, and computed tomography (CT) used in the examination of patients with lung cancer were compared by using as an indicator the following parameters: to make diagnosis of lung cancer, to reveal mediastinal intergrowths, to detect enlarged lymph nodes, pulmonary metastases, and pleural lesions, to obtain information on tumor spread into the chest, to reveal growths into the vascular walls. To evaluate the efficiency of the techniques in solving the above diagnostic tasks, a statistical analysis including the estimation of their accuracy, specificity, and sensitivity was made. Recommendations for examination of patients with lung cancer were drawn up for therapeutic institutions of different types.

Background: With advancements in minimally invasive thoracic surgery techniques, such as video-assisted thoracoscopic surgery and robotic surgery, the design of vascular staplers has evolved to meet the requirements of these procedures. Consequently, newer generations of automatic staplers with improved handling and reduced size have been introduced, such as two-row staplers, which are more maneuverable and less bulky than their three-row counterparts.
Case Presentation: A 68-year-old man with lung cancer underwent a right middle and lower lobectomy due to tumor invasion into the central middle bronchial trunk, rendering the preservation of the middle lobe impossible.

Background: Patient-derived lung cancer organoids (PD-LCOs) demonstrate exceptional potential in preclinical testing and serve as a promising model for the multimodal management of lung cancer. However, certain lung cancer cells derived from patients exhibit limited capacity to generate organoids due to inter-tumor or intra-tumor variability. To overcome this limitation, we have created an in vitro system that employs mesenchymal stromal cells (MSCs) or fibroblasts to serve as a supportive scaffold for lung cancer cells that do not form organoids.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

Background: Patients with non-small cell lung cancer (NSCLC) are prone to developing brain metastases (BMs), particularly those with epidermal growth factor receptor (EGFR) mutations. In clinical practice, treatment-naïve EGFR-mutant NSCLC patients with asymptomatic BMs tend to choose EGFR-tyrosine kinase inhibitors (TKIs) as first-line therapy and defer intracranial radiotherapy (RT). However, the effectiveness of upfront intracranial RT remains unclear.

Background: This study aims to quantify intratumoral heterogeneity (ITH) using preoperative CT image and evaluate its ability to predict pathological high-grade patterns, specifically micropapillary and/or solid components (MP/S), in patients diagnosed with clinical stage I solid lung adenocarcinoma (LADC).
Methods: In this retrospective study, we enrolled 457 patients who were postoperatively diagnosed with clinical stage I solid LADC from two medical centers, assigning them to either a training set (n = 304) or a test set (n = 153). Sub-regions within the tumor were identified using the K-means method.
