A liquid biopsy, also known as fluid biopsy or fluid phase biopsy, is the sampling and analysis of non-solid biological tissue, primarily blood. [ 1 ] [ 2 ] Like traditional biopsy , this type of technique is mainly used as a diagnostic and monitoring tool for diseases such as cancer , with the added benefit of being largely non-invasive.
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
MRD is a form of liquid biopsy, which has other applications such as multi-cancer screening tests. [ 4 ] Molecular tests that uncover minimal residual disease are helpful for directing treatment and monitoring or preventing relapse.
The liquid biopsy is considered a minimally invasive procedure because, unlike other methods of tissue biopsy, such as the solid traditional tissue biopsy, it only necessitates a small amount of blood sample. Liquid biopsy testing has grown in acceptance in clinical settings due to its many advantages, which have assisted in the market's expansion.
For example, since a biopsy only samples a small part of the tumor, clones that resides in a different location may go unnoticed. This can mislead research that focuses on studying the role of tumor heterogeneity in cancer progression and relapse.
Liquid-based cytology is a method of preparing samples for examination in cytopathology. The sample is collected, normally by a small brush, in the same way as for a conventional smear test , but rather than the smear being transferred directly to a microscope slide , the sample is deposited into a small bottle of preservative liquid.
If a serum or leak does not resolve (e.g., after a soft tissue biopsy), taking the patient back to the operating room may be necessary to place some form of closed-suction drain into the wound. In case of lumpectomy , the formation of a seroma at the lumpectomy site has been cited in medical literature as being beneficial, with claims that it ...
