The overall survival rate of patients with clinical stage I esophageal cancer treated with CRT was comparable to that in those treated with esophagectomy, despite a high local recurrence rate. Locally recurrent carcinoma was endoscopically treatable in most patients, with no effect on overall survival. CRT seems to be a viable alternative to esophagectomy in patients with clinical stage I esophageal cancer.
This study showed a strikingly high incidence of esophageal cancer in hypopharyngeal cancer patients. We suppose that the combination of early detection by chromoendoscopic examination and endoscopic resection for associated esophageal cancer in hypopharyngeal cancer patients improve prognosis and maintain quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
