Our study included female breast cancer patients diagnosed at the Municipal Emergency Clinical Hospital Timisoara followed up five years since diagnosis using formalin fixed paraffin embedded tissue. The traditional prognostic factors age, tumor size, histological type, histological grade, anatomical status of the lymph nodes were abstracted from histopathology reports and we set prognostic index the Hormonal cancer survival rate and lymph-node prognosis index.
Hormonal cancer survival rate. Actualizări în tratamentul hormonal al cancerului de sân
We noted positive membranar expressions in 43 cases Negative immunoreactions for E-cadherin have been observed in all cases of lobular carcinomas 4 casesas well as 6 cases of mixed carcinomas. A significant correlation was found between E-cadherin expression and hormonal status, tumor size, histologic type, tumor grade and molecular subtype.
Most of the luminal A and B tumors were E-cadherin positive, while more than half of non-luminal tumors were E-cadherin negative.
Survival rates are different in the negative and positive E-cadherin tumor groups respectively and between luminal and non-luminal groups. E-cadherin expression may be a useful prognostic marker for classifying other subgroups of breast cancer.
