Circulating Tumor Cells
Clinical evidence has indicated that once the tumor progression in the body, each grams of tumor tissue shed one million fresh tumor cells into the nearby blood vessels everyday. These detached tumor cells are called “circulating tumor cells (CTCs)”. Some of the CTCs will invade to another tissue and form a new tumor, which cause metastatic tumor.
According to clinical research, malignant tumor progression in the body should behighly suspected if the CTC counts excess the normal range in 2 ml blood. The CTCcounts is strongly positive correlated to tumor size, and tumor metastasis and prognosisare also correlated to CTC counts.
Comparing to traditional biopsy, liquid biopsy provides the result in 10 days ahead.

What is CTC?
What is CATCHTM-Circulating Tumor Cell testing?
CATCHTM-Circulating Tumor Cell testing is based on negative selection platform. In 2ml blood sample, CTCs will be isolated by using CATCHTM CTC AutoProcessor system, and the number of CTCs will be estimated by AI counting analyzer.
What are the differences of Circulating Tumor Cell testing from other cancer screening tests?
In traditional cancer screening tests, detecting protein-based tumor specific marker is the dominant method. However, the sensitivity and specificity for those tumor markers used in clinical remain inadequate. Circulating Tumor Cell testing is a new cancer screening method that can screen 21 cancer types in a single test. Previous study has demonstrated that the sensitivity and specificity are over 90% and 94% respectively in Circulating Tumor Cell test.
Who will need the test?
Cancer patient
The person who has family history of cancer
The person who expose to high risk factors in life or in work (such as smoking, alcoholic, under high stress, sleep late or high fat diet without vegetable intake, etc.)
Suspicious cancer patient (such as dramatic body weight loss, low appetite, persistent body complaints, etc.)
The person who care their health and willing to apply general medical examination
