Breast pathology after cryotherapy. Histological regression of breast cancer after cryotherapy.

A breast saving treatment is contemporary the preferred method of treatment with comparable results in comparing with mastectomy. In this study were evaluated the effects of cryotherapy by histological verification of changes in post treatment resection specimens. Fifty-three patients in age of 38-81 year with histologically confirmed breast cancer in needle biopsies were managed by cryotherapy between 1999 and 2007.

MicroRNAs with prognostic potential for metastasis in clear cell renal cell carcinoma: a comparison of primary tumors and distant metastases.

Background: MicroRNAs (miRNAs) are regulators of gene expression in tumor development and progression. However, their influence on metastasis of clear cell renal cell carcinoma (ccRCC) is less understood. To determine the role of miRNAs in metastatic progression, miRNA expression in primary ccRCC was compared to distant metastases.

Specific miRNA signatures are associated with metastasis and poor prognosis in clear cell renal cell carcinoma.

Purpose: MicroRNAs (miRNAs) play an important role as regulators of gene expression in tumourigenesis by controlling many biological processes in growth, development, differentiation and apoptosis. Previous studies have shown an altered expression of specific miRNAs in clear cell renal cell carcinoma (ccRCC). But the function in cancerogenesis and metastasis in this tumour type is almost unknown.
