Expression of HER2 in colorectal cancer does not correlate with prognosis.

Estimation of HER2 membranous expression is routinely used in breast and gastric cancers, as both a prognostic and a predictive factor. To date there is no evidence for similar application of HER2 expression in colorectal cancer (CRC) cells. In CRC, HER2 is sometimes overexpressed in the cell membrane and very often in the cytoplasm.

Overexpression of cathepsin B correlates with angiogenesis in colon adenocarcinoma.

Some studies have shown the influence of proteases and vascular density in colorectal primary tumors on spreading and on the course of colorectal cancer. In the present study we have analyzed the relationships between overexpression of cathepsin B protein and angiogenesis intensity in resected colon tumors and their impact on prognosis. It has been investigated in a series of 90 colon cancer patients.

[Elevation of serum Ca 15-3 antigen: an early indicator of distant metastasis from breast cancer. Retrospective analysis of 733 cases].

Unlabelled: Aim of study was to summarize six-year institutional experience with serial evaluation of circulating CA15-3 antigen as a method of early detection of breast cancer relapse.

Material And Methods: CA15-3 concentrations were assayed immuno-enzymatically in the sera of 733 women with breast carcinoma: in 707 cases marker was analyzed serially (every 4 months during follow-up after completion of radical treatment and when the relapse of breast cancer was clinically suspected) and in 26 patients--at diagnosis of locoregional relapse and\or breast cancer dissemination; 5493 assays of the CA15-3 antigen were performed in total. The cut-off limit was established at 30 u/ml.

Anthracycline-induced cardiotoxicity: clinical course, risk factors, pathogenesis, detection and prevention--review of the literature.

Anthracycline antibiotics are widely used antineoplastic agents and their efficacy for the treatment of various haemopoietic or solid tumours has been well established in clinical practice. Cardiotoxicity is one of the most serious side effects of anthracyclines. The risk of cumulative, life-threatening toxic cardiomyopathy limits their therapeutic potential.

Endometrial cancer in patients with breast carcinoma treated with tamoxifen: report of two cases and the literature overview.

Tamoxifen (TAM) is the endocrine treatment of choice in the first-line therapy for all stages of breast cancer, in both pre- and postmenopausal women. Some clinical studies indicated a small but significant increase in the risk of subsequent endometrial carcinoma in breast cancer women who take TAM as an adjuvant therapy. In this study, we present two cases of breast cancer patients in whom endometrial cancer was diagnosed during TAM treatment; the current status of knowledge on the relationship between TAM use and the risk of endometrial cancer is reviewed.
