Chondrosarcoma metastasis to the lung treatment has the following aspects: 1, chondrosarcoma should be resected, it is a primary tumor, and all the tumors should be removed as much as possible by surgical way to delete part of the text.2, after metastasis to the lung, if it is a localized metastasis, and has not spread to metastasize to the whole lung, it is necessary to carry out the resection of the lung at this time.3, in addition to the above mentioned surgical methods, it is necessary to carry out the localized In addition to the surgical methods mentioned above, local radiotherapy should be carried out to kill the tumor cells through radiotherapy.4. Systemic chemotherapy may also be needed because the tumor cells have metastasized, and it is not meaningful to carry out resection purely at this time because the tumor cells have already spread all over the body, and it can be metastasized to the lungs or to other places. At this time, we don’t know exactly how many tumor cells have metastasized, so systemic treatment can be carried out by means of chemotherapy.
