Esophageal cancer: diagnosis and management / 癌症

ABSTRACT

Esophageal cancer is the 7th leading cause of cancer deaths worldwide. While squamous cell carcinoma is the most prevalent histology internationally, adenocarcinoma of the distal esophagus accounts for nearly 50% of cases in developed countries due to the differences in the etiologic factors such as gastroesophageal reflux disease (GERD) and obesity that predominate. While surgery is the mainstay of treatment of this disease, the utilization of chemoradiation, either used postoperatively or neoadjuvantly, has become a standard practice in the United States. What is the optimal management approach is still an area of contention, however, and may be different in different regions around the world. This article reviews some of these controversies, including the role for surgery in patients treated with definitive chemoradiation. At the end, we will also outline recommendations regarding radiotherapy procedures and techniques.
