Laryngeal carcinoma. III. Treatment results in relation to microscopic score.

Abstract

Long term treatment results for 254 patients with laryngeal carcinoma, primarily treated by irradiation, have been analysed according to a microscopic score, indicating the degree of malignancy. Deaths from carcinoma are significantly correlated to the microscopic score. It is strongly indicated that such correlations also exist for local recurrence/residual tumour and regional lymph node metastases. Therefore it is concluded that the microscopic grading system is a valuable prognostic factor supporting, and additional to, the T.N. classification. Larger series are needed in order to obtain correlations in subgroups, and accordingly primary therapeutic consequences can only be suggested, in doubtful cases.
