Japanese scientists recently announced that they have developed a new technology that can detect whether cancer cells of breast and colorectal cancer have metastasized to lymphoid tissue in about 30 minutes.
The technology was developed in collaboration with Osaka University, Sysmex Corporation, and Osaka Police Hospital. The head of the research team and professor at Osaka University, Matsuura Masaaki, announced the results at the recent meeting of the Japan Cancer Society. Using this technique, the extent to which cancer cells metastasize to the lymph nodes can be detected during surgery, and if metastases are found, they can be treated on the spot. Since there is no need for reoperation in the future, the burden on the patient is greatly reduced. The team confirmed that the accuracy of this technique is the same as detailed pathology. Clinical trials have demonstrated that new methods can be used to examine the metastasis of breast and colorectal cancer. The research team is expected to continue to increase sensitivity, expand the types of cancer that apply this technology, and help develop better chemotherapy options.
The principle of the new technology is to remove a part of the lymph nodes, perform grinding, and then apply reagents to check the cancer cell marker "cytokeratin 19". Since the results can be obtained in about 30 minutes, the surgeon can be notified of the presence of cancer metastasis during the operation. If there is a metastasis, the doctor can remove the lymph nodes invaded by cancer cells on the spot.
