Between January 1365 and December 1977, 59 patients with squamous cell carcinoma of the nasopharynx were seen at the University of Michigan Hospital. Of these patients, 40 received treatment in the Department of Radiation Therapy. There were 28 males and 12 females. The age range was 10 to 82 years with an average of 52. All patients were restaged accordiny to the AJC Classification; there were 3 patients in stage II; 18
in stage All

and 19 in stage
IV.
patients were treated with Cobalt-60, parallel opposed portals to a maximum dose of 6600 rads. No attempt was made to treat the lower neck; except in 6 patients with massive adenopathy in which the ipsilateral lower neck was treated. There was no dose reduction at the spinal cord tolerance in any case. There was no evidence of myelopathy in any of the survivors. The 3 and 5 year survivals were 13/40 (32%) and 6/40 (15%) respectively. The average survival for patients who died was 8 months. The most common cause of local treatment failure was tumor recurrence in the anterior aspect of the nasopharynx. Review of port films in this series revealed that this portion of the nasopharynx was not systematically included in every case. We conclude that anterior extension is common in nasopharyngeal carcinoma and that wider anterior margins from lateral portals or the addition of an anterior portal is necessary to prevent local recurrence.

Crude local control for patients eligible for 5 and 10 year follow up was studied. Of the patients treated with surgery alone, 5 year local control was achieved in 30 patients out of 50 (60X), 10 year local control was achieved in 12 out of 27 (44%). Of the 56 pdtients treated by a combination of surgery and radiation, 34 out of 44 (74%) were alive and free of disease at 5 years, and 22 out of 33 (66%) at 10 years.
