Clinical analysis of thyroid carcinoma showing thymus-like differentiation: report of 8 cases.

Thyroid carcinoma showing thymus-like differentiation (CASTLE) is a kind of rare neoplasm of the thyroid gland. Because thyroid CASTLE is rare and difficult to diagnose, its clinicopathologic features have not been well defined, and no universally accepted treatment recommendation is available. We analyzed retrospectively the clinicopathologic data of 8 patients with thyroid CASTLE who underwent surgery and radiotherapy at the Shengjing Hospital of China Medical University between December 2008 and June 2012.

CYP3A5*3 polymorphism and cancer risk: a meta-analysis and meta-regression.

CYP3A5 is a cytochrome P450 superfamily member which is involved in the metabolism of drugs, steroid hormones, and other xenobiotics. Emerging evidences suggest that CYP3A5*3 (rs776746 A>G) polymorphism may play a role in the etiology of carcinogenesis and affect an individual's susceptibility to cancer in humans, but individually published studies showed inconclusive results. This meta-analysis aimed to derive a more accurate estimation of the correlation between CYP3A5*3 polymorphism and cancer risk.

Expression of stromal cell-derived factor 1 and CXCR7 in papillary thyroid carcinoma.

Stromal cell-derived factor 1 (SDF-1) is a chemokine that is expressed in some cancer cells and is involved in tumor cell migration and metastasis. CXCR7, a novel receptor for SDF-1, has been identified recently. Researches demonstrated that interaction between SDF-1 and CXCR7 could play an important role in cancer progression.
