CellSearch™ circulating tumor cell (CTC) test

We use CellSearch™ Circulating Tumor Cell (CTC) test to monitor metastatic breast, colorectal and prostate cancers.

This diagnostic test helps us capture, identify and count circulating tumor cells in a blood sample. CTCs are cancer cells that detach from solid tumors and enter the blood stream. The blood test may be performed prior to the start of therapy and any time during the course of treatment.

The CellSearch test helps us monitor the progression of metastatic cancer and evaluate the effectiveness of treatment. It may be used as early as the first cycle of treatment to evaluate disease progression sooner.
