[Morphologic studies of endometrial cancer for biological assessment of nuclear grading].

Three hundred and eighty-three cases of endometrial carcinoma stage pT1NxM0 had been reviewed retrospectively by making use of histo- and cytomorphological studies. The carcinomas were re-classified and histological and cytological gradings, independent from each other, have been carried out. Typical tumor characteristic of the nucleus (nuclear grading) and their biological importance have been described compared with morphological factors of prognosis (typing, histological grading, depth of myometrial invasion, lymph- and blood vessel invasion). Interrelations and discrepancies between histological and nuclear grading will also be described.
