Drawing blood for liquid biopsy can confirm the diagnosis and track the results of tumor treatment

When lung cancer is found by X-ray photography, or breast cancer is found by breast photography and ultrasound examination, it is often necessary to Further biopsy examination is needed to confirm the diagnosis; however, thanks to medical technology, it can now be confirmed by drawing blood and doing liquid biopsy! In addition, what kind of treatment should be used for tumors, and even to confirm the effectiveness after treatment, liquid sections can also be used to analyze and track it.

Blood can be drawn to isolate tumor cells and detect gene fragments

Lin Shiqiang, director of the Department of Hematology and Oncology of Yadong Hospital, said that when tumors grow in the breast, lungs and liver, they need to be cut. For testing, you can currently draw blood and use liquid biopsy to confirm the diagnosis; because when tumor cells have the ability to run around, they will run into the blood, so blood can be drawn to isolate the tumor cells and detect gene fragments.

For solid tumors such as lung cancer, breast cancer and colorectal cancer

As for liquid biopsy, it is mainly for solid tumors, such as lung cancer, breast cancer and colorectal cancer; Lin Shiqiang The director pointed out that many pharmaceutical companies have established cooperation platforms with many medical centers to provide liquid biopsy tests, which can detect tumor cells for treatment tracking and detect gene fragments to confirm whether targeted drug treatment can be used.

It is more relevant to the use of drugs

Director Lin Shiqiang further pointed out that if the tumor recurs and is difficult to section because of its deep location, this method can be used for examination; Usually there are special genetic tests, such as the EGFR gene for lung cancer, or targeted drugs for breast cancer. This test can also be used to formulate a treatment plan. Usually liquid biopsy tests are more relevant to the use of drugs.

This method is not yet available for screening.

Can blood drawn for liquid biopsy be used as a cancer screening test? Director Lin Shiqiang said that it is not currently possible to use this method for screening, because when the number of tumor cells is very small, it is difficult to do blood tests, so liquid slices can only be used for treatment and tracking; unless the sensitivity of the test is improved, And also need to confirm what kind of tumor it is.
