Circulating Tumor Cell CTC Tests

These tests can detect circulating tumor cells. These cells have been separated from the original tumor and entered the blood, lymphatic system or another part of the body, and may produce a second type of tumor. The circulating tumor cell is then considered to be a factor that play a significant role in the cancer metastasis process. 

Researchers have made significant progress in detecting and separating these cells, but circulating tumor cell tests are not yet 100% accurate. Studies have found that in people with certain types of cancer (breast cancer, prostate cancer, pancreatic cancer, colon cancer, and skin cancer), our test has a sensitivity of 87% to circulating tumor cells and a specificity of 83% (Papasotiriou I. et, 2015).

The Science Behind Circulating Tumor Cell Test

Cancer is caused by severely damaged genetic material, which leads to random genetic instability. Everyone has a unique genetic fingerprint. Therefore, each tumor behaves differently in each individual, which is why our highly personalized test is effective.
A study found that in some groups of cancer patients, the ratio of responding to chemotherapy ranges from 100:5-8. (Royal North Shore Hospital ClinOncol (R Coll Radiol) June 2005;17(4):294).

The Relationship Between The Test and Cancer Treatment

Tumors are composed of several cell subgroups, each of which has different characteristics. One of these subgroups: called cancer stem cell-like cells or tumor-initiating cells; these cells dominate whether the tumor is resistant to treatment and the likelihood of recurrence.

The goal of cancer treatment is to destroy cancer cells. When treating patients, most of the cancer cells are destroyed, but some remain.

During the patient’s remission, the remaining cancer stem cells that can survive may spread to other parts of the body. Therefore, doctors need to detect, discover and explore the characteristics of the remaining cancer stem cells. Our test is used to detect under what circumstances [remaining] cancer cells may respond to treatment.

1. Early Detection of Cancer

Traditional imaging tests for cancer have limited sensitivity. Generally, the cancer is already quite large when the tumor can be detected by imaging. CTC can detect cancer earlier for detailed follow-up when the cancer is yet to be detected by imaging.

2. Help Monitor Existing Cancers

A substantial amount of clinical data found that the level of Circulating Tumor Cell CTC has an indication of the survival rate of patients. For example, in patients with breast cancer, if the level of  Circulating Tumor Cell CTC is higher, it has an indication that the survival rate is relatively poor. On the other hand, there are clinical data showing that the number of CTCs will decrease as the tumor shrinks.

3. Get a Personal Profile of Which Cancer Drugs and Natural Substances can be used to Obtain the Best Therapeutic Effect.

The Circulating Tumor Cell CTC test provides reference for the response of circulating tumor cells to some commonly used chemotherapy drugs, immunotherapy drugs, and integrative cancer treatment drugs.  The Circulating Tumor Cell CTC test can even provide some guidelines for some commonly used nutrients and supplements for cancer patients.

Helping you to make the choice of chemotherapy drugs

There are many kinds of chemotherapeutic drugs.  Drug resistance often appears during treatment. And we know that chemotherapy is generally harmful to the body. If there is a test that can help us analyze which chemotherapeutic drug should be selected, then it can reduce a lot of pain for the patient. By the same token, such Circulating Tumor Cell CTC tests can also help doctors choose targeted drugs and immunotherapy drugs. Of course, the CTC test only gives us useful reference materials, and cannot completely replace the clinical response results.

Nutritional supplements​

Most cancer patients will take a lot of supplements, but how should they choose? This Circulating Tumor Cell CTC test may make a leading assessment of our commonly used anti-cancer supplements and natural remedies. This can undoubtedly help patients make a better choice, strengthen the efficacy of anti-cancer, and also avoid spending wronged money.

Thermal Energy and Radiation Therapy​

In addition, these Circulating Tumor Cell CTC tests can provide an assessment of the sensitivity of cancer cells to hyperthermia or radiation therapy. Through the test of HSP (Heat Shock Protein), we can predict the response of cancer to the above methods.


  • This Circulating Tumor Cell CTC test provides information about the effects of specific anticancer drugs, targeted therapies, and natural therapies on the cancer cells of individual patients.
  • The test combines two procedures, combining molecular and cellular methods: epigenetic analysis and viability analysis.
  • This test is carried out in an ISO-certified laboratory, which is equipped with the latest technology and special software for data analysis.

Type of Test

1. RGCC Oncocount

The Oncocount RGCC test is utilized to identify circulating tumor cells (CTCs) and measure their concentration in the bloodstream. CTCs serve as a significant biomarker, indicating the potential recurrence of cancer when present in the blood.

This test is specifically designed to monitor patients who have previously had cancer and are concerned about its reappearance. By employing the Oncocount RGCC test, healthcare professionals can evaluate the effectiveness of cancer treatment and assess the probability of cancer relapse.

2. RGCC OncoTrace

The Oncotrace RGCC test serves the purpose of detecting the primary tumor in a patient and offering valuable insights into disease advancement and future prognosis.

By examining a blood sample, this test analyzes the presence and abundance of circulating tumor cells (CTCs) while also identifying their specific type (immunophenotype). Consequently, it furnishes critical information regarding the presence, concentration, and characteristics of CTCs.
