Simvastatin prevents skeletal metastasis of breast cancer by an antagonistic interplay between p53 and CD44.

Substantial data from clinical trials and epidemiological studies show promising results for use of statins in many cancers, including mammary carcinoma. Breast tumor primarily metastasizes to bone to form osteolytic lesions, causing severe pain and pathological fracture. Here, we report that simvastatin acts as an inhibitor of osteolysis in a mouse model of breast cancer skeletal metastasis of human mammary cancer cell MDA-MB-231, which expresses the mutant p53R280K.

Fish oil prevents breast cancer cell metastasis to bone.

The data derived from epidemiological and animal models confirm a beneficial effect of fish oil (rich in ω-3 polyunsaturated fatty acids) in the amelioration of tumor growth and progression, including breast cancer. The breast cancer patients often develop bone metastasis evidenced by osteolytic lesions, leading to severe pain and bone fracture. Using a mouse model of MDA-MB-231 human breast cancer cell metastasis to bone, here we show that fish oil diet enriched in DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) prevents the formation of osteolytic lesions in bone, indicating suppression of cancer cell metastasis to bone.

A case of mixed connective tissue disease complicated with thymic carcinoma and Hashimoto's thyroiditis.

We report the case of a 63-year-old woman who suffered from mixed connective tissue disease (MCTD) complicated with thymic carcinoma and Hashimoto's thyroiditis. Although many systemic syndromes associated with thymoma and thymic carcinoma, i.e.
