Whole Blood Real Time Circulating Tumor Cell Testing & Therapy 

The New Technology to Detect the Cancer Cell in the Blood Stream throughout the Body

The technology in screening for cancers are becoming more advanced nowadays. According to the latest medical studies, it was found that CTC or Circulating Tumor Cell is considered to be the new technology for cancer diagnosis.

It was found that when the cancer cells are created and grow in the body, some cancer cells can enter the blood stream even though the cancer tissues are in the initial stage. This information is the reason of why when the symptoms develop, such as obvious lump of cancer is found, the cancer cells have already spread out to other organs. 

Currently, many medical laboratories around the world are trying to detect the cancer cells in blood. Mostly, only 10-200 CC of blood will be collected for cytology and immunology to screen and detect the cancer cells. When considering the facts, it will be found that the blood that is randomly collected for screening is in a very small quantity when comparing with the whole blood that circulates in the body. Hence, there is a chance that a false negative may occur or the cancer cells might not be found if the 10-20 CC of blood does not have the circulation of cancer cells in it even though some cancer cells in the initial stage are already free and circulating in the body. 

Therefore, PDIS technology or Photodynamic Infrared Spectroscopy by Hope4Cancer, the integrative cancer institution, is invented to detect all cancer cells that are circulating in the human blood or what is called Whole Blood Real Time Circulating Tumor Cell, which takes about 1 hour to know the results on whether our blood circulation system contains cancer cells or not. 

Principle of PDIS (Photodynamic Infrared Spectroscopy)

The principle of PDIS says that the cancer cells that circulate in the blood stream are the cells that can be dyed by using some types of photosensitive substance, such as Indocyanine Green (ICG), which is a safe and non-poisonous substance for the normal cells and tissues. 

When we administer the particular substance into the vein, if there is the circulation of cancer cells in our blood circulation system, the cancer cells will be dyed by such substance.

After that, we will detect the cells that have been dyed with the photosensitive substance by using Spectroscope. 

In the examination, we will install the instrument in the blood vessel for 20 consecutive minutes, which is equivalent to 5-6 liters of blood that circulates through the checkpoint or is equivalent to the quantity of whole blood that circulates in the human body. If our blood has a circulation of cancer cells, the Spectroscope will record the total number of cells that can be detected inside the patient’s body. 

PDIS can destroy the cancer cells by using the laser therapy. 

Patients with the detection of cancer cells in the blood stream can receive the treatment to destroy the cancer cells at the same time as the diagnosis by using the low level laser therapy that emitted into the blood vessel. It will be found that the cancer cells that are dyed with ICG, which is the photosensitive substance, when contacting with the laser, the cancer cells will disintegrate. The normal cells that are not dyed with such substance will not provide bad effects in any circumstances. Therefore, this technique aims to eliminate the cancer cells directly and is harmless to the normal cells. 

Who are suitable for PDIS? 

  1. For confirmation and reassurance after the treatment by various methods, such as after the surgery, chemical therapy, and radical irradiation therapy as well as other alternative treatments, like herbal therapy, to check whether there are remaining of cancer cells in the blood circulation system of the patients or not, including the reflection of tumor behaviors that is detected to see whether it still expresses the behavior of being cancer or not. Any tumors that express a malignant spreading behavior or the cancer cells that are spread and flow into the blood stream can be detected by PDIS.

  2. For prevention and therapy, especially in people whose family member has a history and those with risk behaviors of having cancer, such as smoking and exposed to radiation, toxins, and chemicals, including patients with Hepatitis B. PDIS, which will tell the stage and disease development and whether there is the development of cancer in the body or not so that the patient can be aware or receive treatment immediately when detected. 

Limitations of PDIS

PDIS can examine the stem cancer in the blood stream and can only tell whether it is detected or not, together with the use of laser to destroy the cancer cells in the blood stream that are about to spread or disperse. However, it cannot tell what organ the detected cancer cells originated from.   

Hence, those who receive PDIS and the cancer cells are detected should receive treatment by using other techniques in order to strengthen the body’s immune system and mind, balance the diet, and remove toxins from the body, which can increase the chance that the body can fight and conquer the cancer.
