Multidisciplinary management in Merkel cell carcinoma.

Herein, the authors describe the experience with the treatment of Merkel cell carcinoma (MCC) and review the literature regarding MCC treatment regimens. Nine patients underwent treatment due to stage I, II, or III MCC. The median follow up was 39 months.

Prognostic role of c-met expression in breast cancer patients.

Background: Hepatocyte growth factor plays an important role in tumor growth, metastasis and angiogenesis. C-met is HGF's high affinity receptor.

Aim: The aim of the study was to assess the correlations between c-met expression and clinic-pathological factors in breast cancer tissues.

[The importance of determining the prognostic marker YKL-40 in serum and tissues].

YKL-40 is detected in the early nineties not only a glycoprotein secreted by cancer cells, but also of neutrophils, chondrocytes and endothelial cells. Biological function of YKL-40 are not exactly known, it is suggested that this protein participates in many physiological and pathological processes such as proliferation, angiogenesis, mitogenesis and remodelling. It is also a factor antyapoptotic and growth factor for some cells.

Correlation between hepatocyte growth factor receptor and vascular endothelial growth factor-A in breast carcinoma.

The aim of the study was to evaluate the prognostic value of the vascular endothelial growth factor A (VEGF-A) and hepatocyte growth factor receptor (HGFR, c-met) expressions in homogenous group of breast cancer patients. Tumor samples were collected from 98 patients with invasive ductal breast carcinoma stage II treated with primary surgery. We have observed a strong correlation between VEGF-A and c-met.
