IMMUNOHISTOCHEMICAL DIFFERENTIATION OF TRIPLE NEGATIVE BREAST CANCER.

Based on immunohistochemical staining for the basal markers cytokeratin 5/6 (CK 5/6), cytokeratin 14 (CK 14) and P-cadherin, triple negative tumors (TNT) are divided into two groups: 1) basal-like (BL) positive for one or all three markers; and 2) non basal-like (NBL) negative for all three markers. Even though the different origin of the cells of these two types of tumors implies different biological properties, they had been treated as one entity until recently. This paper analyzes TNT collected from 150 patients and distributed into two groups according to the results of immunohistochemical analysis, i.

The impact of human epidermal growth factor receptor-2 status of invasive breast tumors on thermography findings.

Objective: To analyze the impact of prognostic human epidermal growth factor receptor-2 (HER-2) in invasive breast cancers on the findings of thermography tests.

Methods: The study was carried out at the Department of Surgical Oncology and the Department of Pathology, University Clinical Hospital Center, Sisters of Mercy, Zagreb, Croatia, in collaboration with licensed infrared (IR) thermography experts. The study involved 75 female patients diagnosed with invasive breast cancer from May to July 2011.

[Analysis of prognostic factors in breast cancer at University Hospital for Tumors].

Breast cancer is the most common malignant disease in women. It is rare before age 30, whereafter its prevalence rises to reach peak at age 50. Prognostic factors have a very important role in choosing the most appropriate treatment option and making long-term disease prognosis.

Significance of the relative size of a breast tumor in deciding the method of surgical treatment.

Aim: In the surgical treatment of breast cancer there are basically two options: radical and breast-sparing surgery. The main criterion in deciding the mode of treatment is the absolute size of the primary tumor. The purpose of this study was to analyze the relative size of a breast tumor as a prognostic factor and to establish boundary values of the relative tumor size for breast-sparing or radical surgery.

[Leiomyosarcoma of the breast].

A 62-year old patient was treated at our hospital for a palpable change in the upper part of the left breast. The clinical finding was preoperatively confirmed by radiologic, ultrasound and cytology studies, however, the potential biologic process (malignant/benign) was not thus verified. Considering undefined diagnostic nature of the process, biopsy, pathohistology and immunoanalysis were performed to indicate leiomyosarcoma mammae.
