Objective: To analyze the incidence and mortality of lung cancer patients among residents in Yangpu District of Shanghai from 2002 to 2010.
Methods: The data of lung cancer cases in permanent residents of Yangpu district were collected from the database of the registration and management system in Shanghai city. Temporal trend in the incidence of lung cancer was analyzed by using annual percent change (APC) mode1. The survivals were calculated using SPSS 16.0 and Joinpoint Regression Program 3.5.1 software.
Results: A total of 5726 cases of lung cancer were diagnosed from January 2002 to December 2010. Of those, 3865 were males with an average age of onset 70.08 years, and 1861 were females with an average age of onset 70.88 years. The crude incidence rate was 77.36/10(5) in men, significantly higher than 39.31/10(5) in women (U = 24.84, P < 0.01). The standardized incidence rate was 25.23/10(5) in men, significantly higher than 13.47/10(5) in women (U = 13.24, P < 0.01). A total of 5248 cases died of the disease in this period. Of those, 3586 were men. The crude mortality was 71.77/10(5) in men, significantly higher than 35.11/10(5) in women (U = 24.67, P < 0.01). The standardized mortality was 21.72/10(5) in men, significantly higher than 11.08/10(5) in women (U = 13.01, P < 0.01). Both the incidence and mortality rates increased apparently in those older than 45 years. The 1- to 5-year survival rates in all cases were 37.42%, 22.71%, 15.73%, 12.32%, and 10.53%, respectively. The 1- to 5-year survival rates in male cases were significantly lower than those in female cases (P < 0.05 for each comparison). The 1- to 5-year survival rates of the patients whose tumor had been surgically removed were significantly higher than those in the patients without surgery (P < 0.05 for each comparison).
Conclusions: The incidence of lung cancer is close to the mortality in the residents of Yangpu District of Shanghai city. Surgical resection treatment improves the prognosis of lung cancer.

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.
