Background: To determine the value of mediastinoscopy in the mediastinal staging of lung cancer with clinical N2 disease.
Methods: We retrospectively reviewed 87 patients received mediastinoscopy for known or suspected lung cancer, including 83 cervical mediastinoscopies and 4 parasternal mediastinoscopies. All patients were staged clinical N2 for enlarged ipsilateral mediastinal and/or subcarinal lymph nodes (short axis > 1.0 cm) on computed tomography scan.
Results: Of the 87 patients, 61 cases proved N2 disease on mediastinoscopy. The other 26 mediastinoscopy-negative patients underwent thoracotomy for lung resection and mediastinal lymph node dissection in the same operative session. Final pathologic N staging were consistent for mediastinoscopic sampling and surgical dissection in 24 patients. N2 disease was found in 2 patients (false-negative of mediastinoscopy). The sensitivity, specificity, and accuracy of mediastinoscopy were 96.8%, 100%, and 97.7%, respectively. There was no mortality and only 1 complication (1.1%) for all 87 mediastinoscopic procedures.
Conclusions: Mediastinoscopy is a highly effective and safe procedure for the mediastinal staging of lung cancer with clinical N2 disease.

Target cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX) inhibitors; 5-([2,5-Dihydroxybenzyl]amino)salicylamides (Compounds 1-11) were examined for potential anticancer activity, with a trial to assess the underlying possible mechanisms. Compounds were assessed at a single dose against 60 cancer cell lines panel and those with the highest activity were tested in the five-dose assay. COMPARE analysis was conducted to explore potential mechanisms underlying their biological activity.

The epithelial-mesenchymal transition (EMT) assists in the acquisition of invasiveness, relapse, and resistance in non-small cell lung cancer (NSCLC) and can be caused by the signaling of transforming growth factor-β1 (TGF-β1) through Smad-mediated or Smad-independent pathways. (-)-Epigallocatechin-3-gallate (EGCG), a multifunctional cancer-preventing bioconstituent found in tea polyphenols, has been shown to repress TGF-β1-triggered EMT in the human NSCLC A549 cell line by inhibiting the activation of Smad2 and Erk1/2 or reducing the acetylation of Smad2 and Smad3. However, its impact on the Smad-independent pathway remains unclear.

Introduction: Immune checkpoint inhibitors (ICI) have improved the therapeutic arsenal in outpatient oncology care; however, data on necessity of hospitalizations associated with immune-related adverse events (irAEs) are scarce. Here, we characterized hospitalizations of patients undergoing ICI, from the prospective cohort study of the immune cooperative oncology group (ICOG) Hannover.
Methods: Between 12/2019 and 06/2022, 237 patients were included.
Propensity score matched comparison of lymph node upstaging in early-stage lung cancer: open versus minimally invasive surgery with standardized lymphadenectomy.

Background: Lymph node upstaging represents a quality criterion for standardized lymphadenectomy in lung cancer surgery. The aim of the study was to compare whether the quality of standardized lymphadenectomy in lung cancer surgery is comparable in minimally invasive (video-assisted thoracoscopic surgery) and the open approach (thoracotomy). Furthermore, factors associated with lymph node upstaging were assessed, as was its impact on overall survival and progression-free survival.

Background: Dermatomyositis is a chronic inflammatory condition affecting muscles and skin, often associated with an increased risk of cancer. Specific autoantibodies, including anti-TIF1 (Transcription Intermediary Factor 1), have been linked to this risk. We present a case of dermatomyositis in a male patient positive for anti-TIF1 antibodies, subsequently diagnosed with squamous cell carcinoma of the tonsil, a novel association not previously documented.
