The incidence of esophageal cancer, in particular esophageal adenocarcinoma, is increasing, largely due to an increase in risk factors for adenocarcinoma. When esophageal cancer is confirmed by upper endoscopy, staging is required for the optimal selection of patients who should undergo esophageal resection. Neoadjuvant chemoradiation may be able to improve survival after esophageal cancer surg...
Surgery of oesophageal cancer has a high risk demonstrated by the hospital lethality. 72 resections of the oesophagus done by one surgeon are analysed. The following parameters were used: 1) a nutritional index developed in carcinoma patients in a prospective analysis, 2) the EKG result, 3) the lung-function. Adding these 3 indices we get a certain correlation between the judgement of the preop...
Esophageal cancer has a poor prognosis and high mortality rate, with an estimated 16,910 new cases and 15,910 deaths projected in 2016 in the United States. Squamous cell carcinoma and adenocarcinoma account for more than 95% of esophageal cancers. Squamous cell carcinoma is more common in nonindustrialized countries, and important risk factors include smoking, alcohol use, and achalasia. Adeno...
Introduction: Cancer is one of the main causes for mortality and morbidity in the world. Identifying epidemiology and the trend of esophageal cancer may be highly effective in related planning. The present study has been carried out with the aim of exploring the morbidity and trend of esophageal cancer in Iran. Methods: The present study is a type of repe...
By existing censor and skewness in survival data, some models such as weibull are used to analyzing survival data. In addition, parametric and semiparametric models can be obtained from baseline hazard function of Cox model to fit to survival data. However these models are popular because of their simple usage but do not consider unknown risk factors, that's why cannot introduce the be...
