Introduction : Early diagnosis and early treatment are the best ways to improve cancer patient prognoses. We developed ELPS (endoscopic laryngo-pharyngeal surgery) as an endoscopic treatment for superficial pharyngeal carcinoma. However, ELPS has not been applied for cervical esophagus carcinoma because of the narrow working space. We developed a hybrid endoscopic surgery (ESD+ELPS) for borderline lesions between the cervical esophagus and hypopharynx. The purpose of this study was to examine the usefulness and effectiveness of endoscopic treatment for superficial carcinoma of the hypopharynx and cervical esophagus. Patients & Methods : One hundred and sixty-eight patients (265 lesions) of superficial carcinoma of the hypopharynx and nasopharynx were treated between Jan 2000 and Aug 2009 at our institution. Their clinical and histopathological data as well as long-term results were investigated. Results : The endoscopic treatment cases involved 233 lesions. Among these, EMRC (endoscopic mucosal resection by cap-method) was performed on 85 lesions and ELPS on 132 lesions. Hybrid endoscopic surgery (ESD and ELPS) was performed on 7 lesions, which involved both the hypopharynx and cervical esophagus. The overall survival rate at 3 years was 80.2% and at 5 years 66.0%. Cause-specific survival rate at 3 years was 96.6% and at 5 years 94.8%. Conclusion : The results indicated the usefulness and effectiveness of endoscopic treatment for superficial carcinoma of the hypopharynx and cervical esophagus.
