Is routine triple endoscopy cost-effective in head and neck cancer?

Overview

The multicentric occurrence of tumors of the upper aerodigestive tract has been well described, with an incidence ranging from 5 to 16 percent. Detection of a synchronous primary tumor at the time of initial work-up is crucial both for management and final outcome. However, there is a diversity of opinions regarding the extent of the work-up to search for a second primary tumor. Some investigators consider routine panendoscopy to be essential for every patient with a head and neck primary tumor. Routine esophagoscopy and bronchoscopy with bronchial washings in the absence of specific symptoms appear to have minimal benefit and high cost. In our study of 140 consecutive patients with primary squamous cell carcinoma of the head and neck seen over a period of 3 years, detailed history, thorough head and neck examination, routine chest radiograph, and barium swallow when indicated were sufficient to identify 18 patients (13 percent) with a second primary tumor in the upper aerodigestive tract. The synchronous tumors of eight patients were in the head and neck area, seven patients had carcinoma of the lung, and three patients had a second primary in the esophagus. Two patients had three synchronous primaries. Follow-up of these patients ranged from 1 to 4 years. Panendoscopy with cytologic washings was performed routinely. We questioned the cost-effectiveness of routine triscopy in every patient with head and neck cancer.
