Prognostic and Clinicopathological Correlations of Cell Cycle Marker Expressions before and after the Primary Systemic Therapy of Breast Cancer.

We aimed to analyze the expression of cell-cycle regulation markers - minichromosome maintenance protein 2 (MCM2), Ki-67, Cyclin-A and phosphohistone-H3 (PHH3) - in pre-treatment core-biopsy samples of breast carcinomas in correlation with known predictive and prognostic factors. Totally 52 core biopsy samples obtained prior to neoadjuvant therapy were analyzed. Immunohistochemistry was performed to analyze the expression of MCM2, Ki-67, Cyclin A and PHH3, which were correlated with the following clinicopathological parameters: clinical TNM, tumor grade, biological subtype, the presence of tumor infiltrating lymphocytes (TIL), pathological tumor response rate to the neoadjuvant therapy and patient survival.

LAPTM4B gene copy number gain is associated with inferior response to anthracycline-based chemotherapy in hormone receptor negative breast carcinomas.

Purpose: To determine the associations between lysosomal-associated transmembrane protein 4b (LAPTM4B) gene copy number and response to different chemotherapy regimens in hormone receptor negative (HR-) primary breast carcinomas.

Patients And Methods: Two cohorts were analyzed: (1) 69 core biopsies from HR-breast carcinomas treated with neoadjuvant chemotherapy (anthracycline based in 72.5% of patients and non-anthracycline based in 27.

Breast carcinoma subtypes show different patterns of metastatic behavior.

The aim of our retrospective study was to analyze patterns of subtype specific metastatic spread and to identify the time course of distant metastases. A consecutive series of 490 patients with breast cancer who underwent surgery and postoperative treatment at Semmelweis University, Hungary, and diagnosed between the years 2000 and 2007 was identified from the archives of the 2nd Department of Pathology, Hungary. Molecular subtypes were defined based on the 2011 St.

[Latest international guidelines for screening, prevention and treatment of familial breast cancer - implications for the relevant practice in Hungary].

Introduction: Screening, prevention and treatment of familial breast cancer require a multidisciplinary approach. New guidelines were published in the United Kingdom for the management of familial breast cancer.

Aim: The authors summarise these new guidelines and analyse the relevant practice in Hungary.

[A giant myxoid leiomyoma mimicking an inguinal hernia].

Leiomyoma is a rare, smooth muscle tumour that can occur everywhere in the human body. The authors present the history of a 60-year-old female, who had a giant, Mullerian type myxoid leiomyoma in the inguinal region mimicking acute abdominal symptoms. After examination the authors removed the soft tissue mass in the right femoral region reaching down in supine position to the middle third of the leg measuring 335 × 495 × 437 mm in greatest diameters in weight 33 kg.

[Immunohistochemical phenotype of breast carcinomas predicts the effectiveness of primary systemic therapy].

The purpose of the study was to identify breast cancer subtypes by immunohistochemistry likely to respond to neoadjuvant chemotherapy and to analyze the used chemotherapy regimen and the range of response rates. Analysis of a collected database was performed. Ninety-two patients were identified in our files who received neoadjuvant chemotherapy between 1998 and 2009.

Stromal matrix protein expression following preoperative systemic therapy in breast cancer.

Purpose: Stromal alterations are observed following preoperative systemic therapy in breast cancer. The aim of the present study was to analyze the qualitative and quantitative changes of representative tumor stroma proteins in the context of neoadjuvant therapy and the response of patients undergoing preoperative systemic therapy.

Experimental Design: Fifty women receiving preoperative systemic therapy were evaluated for clinical and pathologic parameters.

[Failure of diagnosing pancreatic tumors in the course of laparoscopic cholecystectomy: surgical lessons].

Introduction: In Hungary surgeons perform approximately 24000 cholecystectomies per year. Nowadays the choice of treatment of uncomplicated cholelithiasis is laparoscopic cholecystectomy. The advantages and popularity of the procedure are well known; otherwise the exploration of the abdominal cavity is not so complete than during open surgery.
