Detecting circulating tumor cells in patients with advanced non-small cell lung cancer

Y. H. Xu, Zhou, J., and Pan, X. F., Detecting circulating tumor cells in patients with advanced non-small cell lung cancer, vol. 14, pp. 10352-10358, 2015.

We explored the expression and clinical significance of circulating tumor cells (CTCs) in patients with advanced non-small cell lung cancer (NSCLC). Sixty-six patients with advanced NSCLC at the Oncology Department of Jinzhou Hospital were selected as an observation group between February and December 2013. Healthy volunteers and 20 benign lung disease patients were taken as a control group. Peripheral blood CTCs in the observation and control groups were detected using the CellSearch®.

Effects of Herceptin on circulating tumor cells in HER2 positive early breast cancer

J. - L. Zhang, Yao, Q., Chen, J. - H., Wang, Y., Wang, H., Fan, Q., Ling, R., Yi, J., and Wang, L., Effects of Herceptin on circulating tumor cells in HER2 positive early breast cancer, vol. 14, pp. 2099-2103, 2015.

The objective of this study was to determine the changes in peripheral blood circulating tumor cells in HER2-positive early breast cancer before and after Herceptin therapy, and to explore the effects of the HER2 gene and Herceptin on circulating tumor cells. CK19 mRNA expression in peripheral blood was evaluated by qRT-PCR as an index of circulating tumor cells in 15 cases of HER-2-positive breast cancer and 18 cases of HER2-negative breast cancer before, and after chemotherapy as well.
