Carcinoma of the nasopharynx: analysis of treatment results in 167 consecutively admitted patients.

Abstract

Radiotherapy with curative intent was administered to 159 of 167 consecutively admitted patients with nasopharyngeal carcinoma. The classification (UICC 1982) gave the staging: stage I 8%, stage II 2%, stage III 28%, and stage IV 61%. The actuarial local tumor control was 54% and correlated to the T-classification. Primary control of neck nodes was 67% but was not correlated to the N-classes. Distant failure occurred in 20% of the patients; this was correlated to the N-classification. The 10-year actuarially corrected survival rate was 37% (stage I+II 60%, stage III 49%, stage IV 27%). Late reactions were seen in 69%, and most patients had mild to moderate xerostomia. Men with high hemoglobin had a better prognosis than men with values in the lower part of the normal range. It is concluded that primary control in the T- and N-positions is the parameter most crucial to success.
