Significant Prognostic Factors in Breast Cancer of Japanese Women : Special Reference to Nuclear Grade and Sinus Histiocytosis

Abstract

Based on clinicopathological observations of 91 female patients with breast cancer in Miyagi Prefecture, TNM stage, histologic type, grade of infiltrative growth tendency (INF), vessel involvement, lymph node metastasis, nuclear grade and sinus histiocytosis were assessed in relation to prognosis. Follow-up studies indicated that 73.6% of the patients survived more than five years after operation. Among the factors sub-mitted to histologic evaluation, nuclear grade, INF, vessel involvement and lymph node metastasis were apparently correlated to prognosis, while sinus histiocytosis was not significantly related to it, except for patients with positive nodes.
