title: Esophageal cancer.
abstract: Papers published in the English literature on esophageal cancer in 1999 were retrieved by a MEDLINE search. Selective publications were reviewed in light of current knowledge. Many studies were performed to refine staging methods of esophageal cancer, especially in the use of endoscopic ultrasound. Although better designs have overcome the problem of nontraversable tumors, its use in staging after neoadjuvant therapies remains suboptimal. Important studies on various surgical techniques were reported, including randomized trials on different routes of reconstruction after esophageal extirpation, and the updated results of transhiatal resections. In contrast to the minimalist approach of transhiatal resection, investigators from both East and West have also described the pathologic basis of lymphatic spread of esophageal cancer and its implications, favoring more radical lymphadenectomy. Another avenue that was explored is the use of neoadjuvant therapies to improve outcome. Different regimens were studied, and many papers focused on the molecular prediction of favorable response to such therapies. Overenthusiastic adoption of multimodality treatments is cautioned, however, in that they have not been validated. Further work is much needed in this area of research.
