Abstract

Introduction

It is known that invasive breast carcinoma consists ductal or lobular structures. However, currently, only about%10 are classified as specific types. Some of the histopathological subtypes have characteristic features in the terms of prognosis.

Material&Methods

We evaluated non metastatic invasive breast carcinoma patients according to age, menopausal status, histopathological subtype, hormone receptor status, stage and HER 2 status.

Results

A total of 77 patients were included in the study.  In the group of Invasive Ductal Carcinoma (IDC), 53 patients (%68.8) had a meanage of 55,2(range 35-83). 36 of them (%69) were post menopausal, 17  (%31) were premenopausal.. Staging of these patients were Stage I, II and III  10, 28 and 15 respectively. 43 patients (%81) had positive estrogen (ER) or progesterone receptor. Seventeen patients(%32)  had positive and 29 (%53) had negative HER 2 status

Nine patients(%11.6) with the meanage of 56,1 (range 34-76) were invasive lobuler carcinoma (ILC). Only three of them (%33,3) were premenopausal. Staging of these cases were Stage I, II and III 1, 5 and 3 respectively. All of ILC patients had ER or PR positive. Additionally three patients had positive and four patients were negative HER 2 status

There were seven cases (%9) with mixed type (lobular +ductal or any other of these two histologictype of tumor) of breast carcinoma. Only 2 patients were premenopausal. Meanage were 56,4 (36-71). All of them had positive with ER or PR while 3 cases were HER 2 status positive.

            There were eight patients  (%10,3) as specific types including two noroendocrin carcinoma,two intracyctic carsinoma, two meduller carcinoma, one papillary breast cancer and one occult breast carcinoma.

Discussion

We identified consistent rates with the literature on the analysis of histopathological subtypes. Furthermore, hormone receptor positivity was also consistent with the literature as ILC was higher than IDC.
