Aim. Despite the great progress in cancer treating, the breast cancer remains lethal in 15 % cases. Regardless of the many years of research and extensive experience in the treatment of this type of cancer, one of the main problems in diagnosis and therapy is its high clinical and genetic heterogeneity. Thereby the identification of markers for personalized treatment of patients is still an actual issue. Methods. Collection of clinical material, RNA isolation, and expression analysis of ITSN2 and TKS5 isoforms using quantitative real time PCR with fluorescence-labeled probes. Results. We have found that ITSN2-S expression is reliably reduced in HER2/neu-positive tumors with poor prognosis. There were no significant differences in the expression of ITSN2-L and TKS5-L in the analyzed samples. Conclusions. These studies have demonstrated the possible use of ITSN2 short isoform (ITSN2-S) as a prognostic marker for breast cancer. Keywords: breast cancer, ITSN2, TKS5, expression analysis.

Primary breast lymphoma (PBL) represents 0.04-0.5% of all malignant breast tumors, <1% of all patients with non-Hodgkin’s lymphomas and 1.7-2.2% of all patients with extra nodal lymphomas. Despite the high prevalence of breast cancer, primary breast lymphoma is very rare. We report a rare case of PBL, successfully treated with surgery, chemotherapy and radiotherapy. This is the first case of PBL to be reported from Sudan to our knowledge.

The ability of breast tumors to synthesize sex steroid hormones is well recognized and their local production is thought to play a role in breast cancer development and growth. The aim of this study was to estimate local intra-tumoral and circulating levels of Estrone (E1), Estrone Sulfate (E1S), Estradiol (E2), Estriol (E3), and Testosterone (T) in 33 pre- and postmenopausal women with primary breast cancer in comparison to 12 pre- and postmenopausal women with benign breast tumors. The mean levels of the studied sex hormones were higher in serum and tumor tissue of breast cancer women than those with benign breast tumors apart from Testosterone which showed a significant decrease in pre- and postmenopausal women with breast cancer (P< 0.001 for follicular phase,P< 0.001 for luteal phase, andP< 0.001 for postmenopausal). The levels of the five hormones were significantly higher intra-tumoral than in serum of both benign and malignant breast tumor women with E1S as the predominant estrogen. There was only a positive significant correlation between serum and tumor tissue levels of E1(rs= 0.52,P< 0.05 for follicular;rs= 0.63,P< 0.05 for luteal andrs= 0.58,P< 0.05 for postmenopausal) and a significant correlation between serum and tumor tissue of T (rs= 0.64,P< 0.05 for follicular;rs= -0.51,P< 0.05 for luteal andrs= -0.81,P< 0.04 for postmenopausal).

Background: During tumor progression, circulating monocytes and macrophages are actively recruited into tumors where they alter the tumor microenvironment to accelerate tumor progression. In response to multiple microenvironmental signals from the tumor and stromal cells, macrophages change their functional phenotypes. Based on their function, macrophages are commonly classified into both, classical M1 and alternative M2 macrophages. M2-like tumor-associated macrophages promote breast tumor growth and survival, and may migrate into the peripheral blood. However, the level of circulating M2/M1-like monocyte ratio in the peripheral blood of breast cancer patients has not been yet clarified. Aim: To compare peripheral blood M2/M1 monocyte ratio among breast cancer patients, benign breast tumor patients and healthy subjects. Also, to investigate the role of peripheral blood M2/M1 monocyte ratio as a circulating breast cancer tumor marker and to asses the validity of this marker in differentiation between benign and malignant breast tumors. Methods: Flow cytometry technique was used to determine the peripheral blood M2/M1 monocyte ratio in three groups of subjects, i.e. 45 patients with breast cancer, 40 patients with benign breast tumor, and 40 healthy subjects as a control group. The results of carbohydrate antigen15-3 (CA15-3) determination were analyzed comparatively. Results: The peripheral blood M2/M1 monocyte ratio in patients with breast cancer (0.27±0.1) was significantly higher (P<0.001) than that in healthy subjects (0.07±0.05) and than in benign tumor subjects (0.08±0.04). The area under the receiver operating characteristic (ROC) curve of peripheral blood M2/M1 monocyte ratio determination was significantly higher (P≤0.001) than that of CA15-3 levels. Conclusion: M2/M1-like monocyte ratio is of a high diagnostic value for breast cancer and is a promising differentiating marker between benign and breast cancer tumor groups.
