title: Panendoscopy in screening for synchronous primary malignancies.
abstract: The entire upper aerodigestive tract must be evaluated at the time of initial tumor evaluation in patients with squamous cell carcinoma of the head and neck. The necessity of panendoscopy (laryngoscopy, bronchoscopy, esophagoscopy) in this evaluation has not been demonstrated convincingly. Between January 1, 1984 and December 31, 1985, 208 patients with previously untreated squamous cell carcinoma of the head and neck were analyzed prospectively. These patients underwent head and neck examination, chest radiograph, barium esophagram, and panendoscopy. Fifteen (7.2%) had synchronous malignancies of the upper aerodigestive tract. In four patients (1.9%) the synchronous primary tumor was found only by endoscopy. Three patients (1.4%) had cancers of the hypopharynx. One patient (0.5%) had a bronchial cancer detected only on bronchoscopy. No tumors were detected by esophagoscopy that were not also seen on barium esophagram. We conclude that endoscopic examination of the hypopharynx is very helpful in screening for additional tumors in head and neck cancer patients, but routine esophagoscopy cannot be supported. Screening bronchoscopy cannot be strongly supported due to its very low yield.
