From the data collected in the Cancer Registry of Calvados [France] a screening program for neoplastic lesions of the whole upper digestive and respiratory tract was performed in a canton where esophageal cancer incidence is very high. Men (137) underwent this examination for mouth, pharyngo-larynx and esophagus. No neoplastic lesion was revealed but histologic and cytologic swabs showed some abnormaliteis that are now being studied.
