OBJECTIVES Although endoscopic ultrasound (EUS) staging of esophageal cancer is established in clinical practice, high-quality evidence about its impact on patient outcomes is not available. This study aims to determine the impact of EUS for esophageal cancer staging on patient management and survival. METHODS A systematic review was conducted using Medline, PreMedline, Embase, and The Cochra...

Survival of all non-small cell lung cancer (NSCLC) patients is disappointing, with a 5-year survival of 18%. Staging NSCLC patients is crucial because it determines the choice of treatment and prognosis. Clinical staging is a complex process that comes with many challenges and with low accuracy between the clinical and pathological stage. Treatment modalities for stage I-III NSCLC consist of su...

Previous studies of pancreatic ductal adenocarcinoma (PDAC) have demonstrated that the addition of tumor grade to the 7th American Joint Committee on Cancer (AJCC) staging can provide improved prognostication and that the recently proposed 8th edition AJCC staging exhibited superior reproducibility to the 7th edition in resectable PDAC. Thus, we aimed to combine tumor grade and 8th AJCC stage t...

BACKGROUND This study compared the performance of endoscopic ultrasonography (EUS) and multislice spiral computed tomography (MSCT) in the preoperative staging of gastric cancer. METHODOLOGY/PRINCIPAL FINDINGS A total of 610 patients participated in this study, all of whom had undergone surgical resection, had confirmed gastric cancer and were evaluated with EUS and MSCT. Tumor staging was ev...

For a long time lung cancer was associated with a fatalistic approach by healthcare professionals. In recent years, advances in imaging, improved diagnostic techniques and more effective treatment modalities are reasons for optimism. Accurate lung cancer staging is vitally important because treatment options and prognosis differ significantly by stage. The staging algorithm should include a con...

Staging is of the utmost importance in the evaluation of a patient with non-small cell lung cancer (NSCLC) because it defines the actual extent of the disease. Accurate staging allows multidisciplinary oncology teams to plan the best surgical or medical treatment and to predict patient prognosis. Based on the recommendation of the International Association for the Study of Lung Cancer (IASLC), ...

Proposition 1: As I argued in the paper, there is no equilibrium in which the dictator uses a pure strategy and the ruling coalition conditions its decision to stage a coup on the observed signal. In any equilibrium in mixed strategies, (i) the ruling coalition stages a coup with probability βθ such that, given the correlation between his actions and the signal θ, the dictator is indifferent be...
