title: Prognostic significance of the Ackerman classification and other histopathological characteristics in breast cancer. An analysis of 1,349 consecutive cases with complete follow-up over seven years.
abstract: Survival rates during a follow-up period of more than seven years were analyzed in 1,349 women with breast cancer in relation to the histo-pathological classification of female breast cancer proposed by Ackerman and to other commonly used histo-pathological criteria, including the axillary node status. The information was collected prospectively during a case-control study. Major emphasis was placed on multivariate evaluation. In analyses based on the histo-pathological findings in the mastectomy specimen alone, the Ackerman grouping was found to be of prognostic value, but apart from nuclear polymorphism the other recorded characteristics (histo-pathological type, histological grading, lymphocyte infiltration, and sinus histiocytosis) did not give any prognostic information. When the axillary node status was included in the multivariate models, the presence of axillary metastases correlated well with the prognosis and the Ackerman classification provided no significant additional information. The results indicate that in cases where the histopathological axillary status is known, little additional prognostic information can be gained from traditional histo-pathological evaluation over and above this status. However, the Ackerman classification and the degree of nuclear polymorphism separate distinct prognostic groups with the same degree of difference in observed survival rates as one discriminated by the axillary node status.
