SERUM LEPTIN LEVEL IN BREAST CANCER.

Leptin is a polypeptide which is mostly produced in white fat tissue and is an important proinflammatory, proangiogenic, proinvasive and mitotic factor. There is ever more evidence suggesting the key role of leptin in the occurrence of breast cancer. The aim of the study was to investigate serum leptin levels in patients with benign breast tumors, as well as in various breast cancer phenotypes, taking into account leptin levels connected to menopausal status and body mass index (BMI).

Independent factors FOR poor prognosis in young patients with stage I-III breast cancer.

Breast cancer is the most common malignancy in the population of women under 40 years of age. Young age is an independent factor for poor prognosis. In this research, we tried to establish other factors for poor prognosis in stage I-III breast cancer.

BREAST CANCER IN YOUNG WOMEN: PATHOLOGIC AND IMMUNOHISTOCHEMICAL FEATURES.

- A young woman with breast cancer is considered to be a woman younger than 40. According to the literature, breast cancer in the population of young women usually is of a higher histologic grade, unfavorable hormonal status, and overall higher mortality rate when compared with breast cancer occurring in older population. We compared pathologic and immunohistochemical features of breast carcinoma in women under 40 years of age with the respective features in women over 60 years of age.

Differential Expression of TFF Genes and Proteins in Breast Tumors.

The objective of this study was to determine differential expression of TFF1, TFF2 and TFF3 genes and proteins in breast tumor subtypes. In addition, we investigated the correlation between TFF genes within tumor subgroups, and TFF genes with clinical and pathologic characteristics of the tumor. Study group included 122 patients with surgically removed breast tumors.

Prevalence of the palmaris longus in relation to the hand dominance.

Purpose: The incidence of left-handedness in the general population is between 8 and 15%. There is a presumption that the prevalence of palmaris longus muscle differ between right-handed and left-handed people. This prospective study was conducted to determine the prevalence of the palmaris longus in relation to the hand dominance.
