Comparative investigation of two variants of Lewis lung carcinoma cells (LLC and LLC/R9) growing under nutrient deficiency caused by long-term incubation without growth medium replacement was performed. It was established that LLC/R9 cells which in contrast to LLC cells had a high sensitivity to antitumor antiangiogenic therapy (AAT) revealed a high dependence of their survival from glucose level in growth medium as well as high capacity to autophagy under nutrient deficiency. Perhaps high autophagy activity in tumor cells may be considered as a marker of tumor AAT sensitivity.

The widespread adoption of high-resolution computed tomography (CT) screening has led to increased detection of small pulmonary nodules, necessitating accurate localization techniques for surgical resection. This review examines the evolution, efficacy, and safety of various localization methods for small pulmonary nodules. Studies focusing on localization techniques for pulmonary nodules ≤30 mm in diameter were included, with emphasis on technical success rates and complication profiles.

Non-small cell lung cancer (NSCLC) has emerged as one of the most prevalent malignancies worldwide. N6-methyladenosine (mA) methylation, a pervasive epigenetic modification in long noncoding RNAs (lncRNAs), plays a crucial role in NSCLC progression. Here, we report that mA modification and the expression of the lncRNA stem cell inhibitory RNA transcript (SCIRT) was significantly upregulated in NSCLC tissues and cells.

Recent studies suggest that lung adenocarcinoma cells are closely associated with the tumorigenesis of large-cell neuroendocrine carcinoma via cellular transformation. However, morphological evidence, along with genetic abnormalities before, during, and after transformation, is quite limited. We present here a case of combined large-cell neuroendocrine carcinoma and adenocarcinoma exhibiting acinar and solid patterns.

Non-invasive assessment of pulmonary nodule malignancy remains a critical challenge in lung cancer diagnosis. Traditional methods often lack precision in differentiating benign from malignant nodules, particularly in the early stages. This study introduces an approach using multifractal spectrum analysis to quantitatively evaluate pulmonary nodule characteristics.

Pulmonary sarcomatoid carcinoma (PSC) is a rare non-small-cell lung cancer with sarcomatous components or sarcomatoid differentiation, high degree of malignancy, and insensitivity to chemotherapy or radiotherapy. The management of PSC coexisting with tuberculosis (TB) poses a greater challenge, as it necessitates concurrent administration of both anti-TB and anti-neoplastic therapies. The efficacy of anti-PD-1 immunotherapy in non-small-cell lung cancer is promising, but its safety in patients with co-existent TB remains uncertain.
