Polymorphisms in Survivin ( Gene) Are Associated with Age of Onset in Breast Cancer Patients.

Survivin, encoded by gene (baculoviral IAP repeat containing 5), belongs to the family of inhibitors of apoptosis proteins (IAPs). In mammalian cells it participates in the control of mitosis, apoptosis regulation, and cellular stress response. Its expression is increased in almost all types of cancers.

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.

Case report of nodular melanoma within congenital melanocytic nevus- primary closure challenge.

Introduction: Congenital melanocytic nevi (CMN) are present in 1-2% of newborn infants. The size of CMN defines the risk of developing melanoma which is estimated from 5-10%, especially in lesions that are located across the spine.

Presentation Of Case: Herein we report a case where nodular melanoma was discovered on the periphery of medium sized CMN in a high risk patient.

Expression of genes responsible for the repair of mispaired bases of the DNA (MLH1) in invasive ductal breast carcinoma.

Breast cancer is a heterogeneous group of diseases determined and distinguished by cellular type, gene expression and clinical signs and symptoms. Identification of histological and biological markers is of great value in predicting the progression of tumor growth and anticipating the expected response to various treatment options. Due to a high degree of cell proliferation in breast tumors and high genetic instability of these tumors, as a consequence of defective DNA repair mechanisms, chemotherapy as a treatment option often renders very successful results.

Influence of hormonal status on thermography findings in breast cancer.

The aim of this study was to investigate the association of infrared imaging findings and hormone receptor (estrogen and progesterone) status in breast cancers. The study was carried out at Department of Surgical Oncology and Department of Pathology, Sestre milosrdnice University Hospital Center, in collaboration with licensed infrared thermography experts. The study involved 75 female patients with invasive breast tumors.

[Epidemiology of invasive breast cancer according to histopathologic and immunohistochemistry prognostic factors].

The aim of this study was to analyze the TNM classification factors of invasive breast cancer that can be affected by the national program for early detection of breast cancer in the Republic of Croatia. The other analyzed factors related to histology and immunohistochemistry have no such impact as they are related to biological behavior and aggressiveness of malignant breast tumors, thus providing useful predictive and prognostic information. The study was performed at Department of Oncologic Surgery, Sestre milosrdnice University Hospital Center, and included 75 patients surgically treated for invasive breast cancer during the period of one month in 2011, mean age 64 +/- 11.

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.

Primary Ewing's sarcoma of the kidney: a case report.

Primary adult Ewing's sarcoma is a rare entity. They most commonly occur in children and young adults. 6% of them are localized extraosseously.

Rectal metastasis from lobular carcinoma of the breast: a case report.

Rectal metastases from breast carcinomas are very rare. They often occur in lobular invasive breast carcinoma (ILC), usually after a long disease-free period. It is important to be aware of these unusual metastatic patterns of ILC of the breast because of the possibility of systemic therapy.

Histological types of polypoid cutaneous melanoma II.

The aim of this study was to ascertain which histological types of melanoma can clinically and morphologically appear as polypoid melanomas. In 645 cases of primary cutaneous melanoma we have analyzed criteria for diagnosis of polypoid cutaneous melanoma and afterwards we have analyzed growth phase in each polypoid melanoma, histological type of atypical melanocytes, the number of epidermal ridges which are occupied by atypical melanocytes, and distribution according to age, sex and location, as well as the disease free survival. According to the criteria for polypoid melanomas we have found 147 (22.

[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.

Radiotherapy of stage IEA primary breast lymphoma: case report.

A 47-year-old woman was referred for the treatment to our Hospital because of a palpable nodule in the upper medial quadrant of her right breast. After tumor excision, pathohistological examination showed a follicular center cell lymphoma grade 2, B-cell type (CD20+, bc16+, CD10+, bcl2+). The final diagnosis was stage IEA primary extranodal non-Hodgkin s breast lymphoma.

Rare complication of breast cancer irradiation: postirradiation osteosarcoma.

Radiation-induced osteosarcoma is a rare complication of radiation therapy for breast cancer. The authors present a 60-year-old patient in whom osteosarcoma of the chest wall developed 5 years after modified radical mastectomy and radiation therapy for breast cancer. One year after resection of the chest osteosarcoma, metastasis to the contralateral axillary lymph nodes developed and these were removed.

[Surgical treatment of irradiation-induced sarcoma after treatment for breast carcinoma, personal experience: 4 case reports] ].

In the Department of Plastic Surgery of "Dubrava" University Hospital from 1993 to 1999 four patients were treated for radiation induced sarcoma. All of the patients were formerly operated for breast cancer and irradiated postoperatively. The mean time span between radiotherapy and development of sarcoma was 4.

RT-PCR detection of tyrosinase, gp100, MART1/Melan-A, and TRP-2 gene transcripts in peripheral blood of melanoma patients.

Aim: To detect the expression of genes encoding tyrosinase, gp100, MART-1/Melan A, and tyrosinase-related protein-2 (TRP-2) in peripheral blood of melanoma patients by reverse transcription-polymerase chain reaction (RT-PCR).

Methods: Nineteen peripheral blood samples were obtained from 17 melanoma patients. When tested, 15 of them presented with clinically detectable metastatic disease.
