Correlation between 5-year survival of T1-T2N0 breast cancer and some pathological parameters

: In order to more clearly define the factors influencing prognosis, 113 cases of T1-T2N0 breast cancers, all operated on by means of radical mastectomy, were reviewed. The following pathologic parameters were analyzed in relation to 5 years survival: histological type, nuclear grading, vascular embolization, size and border of the tumour, and sinus histiocytosis, diffuse cortical hyperplasia and germinal center hyperplasia of axillary nodes. We observed a close correlation between the presence of sinus histiocytosis and prognosis, as many authors have reported. Diffuse cortical hyperplasia stands out from our data as the most unfavourable prognostic factor.
