The influence of pathomorphological parameters (keratinization, grading, nucleolar organizer region (NOR) counts, automatic analysis of micrographs) on prognosis was determined for 284 patients with carcinomas of the oropharynx or hypopharynx. Keratinization was found to have no influence on prognosis. Histopathological grading and automatic analysis of micrographs with mark 22 were seen to be of major relevance. Patients with grading 3 were noted to have a poorer prognosis than those with gradings of 1 or 2. This latter finding was statistically significant. Although the absolute NOR counts had no influence on prognosis, they did show a statistically significant effect on the extent of lymphogenic formation of metastases. Cox regression analysis of clinical and pathomorphological parameters revealed that combination therapy, tumor grading, and mark 22 of automatic analysis of micrographs were important factors relevant to prognosis.
