Most of the patients with hypopharyngeal cancer had advanced stage lesions (III or IV). This may account for the poor prognosis. We investigated the process of diagnosis in 45 patients treated in our clinic during the past nine years. In 32 of them (71%) advanced disease was diagnosed before treatment. The interval between the onset of initial symptoms and the definite diagnosis before treatment ranged from less than one month to more than 12 months (average of 5.1 months). After the first medical examination, nine of the 45 patients required more than three months before diagnosis of hypopharyngeal cancer was comfirmed. At the first visit for consultation about the initial symptoms, 32 patients visited an otolaryngologist, and 13 patients visited an internist or a general surgeon. Three patients who were older than 74 years and complained of pharyngo-laryngeal discomfort were included in the above group of nine patients receiving a late diagnosis. The present study indicates that it is empirically feasible to diagnose or rule out hypopharyngeal cancer in elderly patients complaing of abnormal sensation in the pharyngo-laryngeal portion. Since hypopharyngeal cancer in the early stage is not easily detectable in the usual manner, such as indirect laryngoscopy or hypopharynx fluoroscopy, endoscopy with a well-equiped fiberscope and biopsy or cytology should be conducted periodically, if signs suggest the presence of hypopharyngeal cancer.
