The Future of CTC

Slide 24

April 2011

We hope that we have demonstrated the important role of CTC analysis in the management of patients with metastatic breast, colorectal, and prostate cancer. Additional studies are being performed to examine the clinical utility of the CellSearch assay for other tumors such as urothelial cancer, lung cancer, and melanoma. Possibly most importantly are additional studies to determine the utility of this technology for guiding proper patient treatment. For example, a study by the Southwest Oncology Group, is investigating a strategy of changing or maintaining therapy based on circulating tumor cell levels in patients with metastatic breast cancer. This trial might answer the question of whether changing treatment based on an elevated or increasing circulating tumor cell count alone is warranted.

In closing, this concludes our presentation on the use of the CellSearch System for the detection of circulating tumor cells in patients with metastatic cancer. We hope that this information has been useful. Thank you.
