Interventional therapy for osteogenic metastatic bone tumor

The incidence of osteogenic metastatic bone tumor is not high, most common is prostate cancer, can show multiple osteogenic bone metastases throughout the body. The first is to take a certain amount of contrast agent orally, understand the scope of the lesion through the distribution of the contrast agent in the body, determine the nutrient vessels of the tumor through imaging examination, and then carry out embolization and occlusion of the nutrient vessels to reduce the blood supply of the lesion, so that the tumor will starve to death after losing blood supply and shrink the lesion. This is a treatment method. Another approach is to intervene, to intervene, to find the feeding vessels of the tumor locally, and to block the feeding vessels with gelatin sponge microspheres or some TACE (sound), to reduce blood flow to the lesion, to shrink the tumor locally, and another approach is to invasively intervene through the artery, insert a catheter, and then inject contrast medium. The nutrient blood vessels of the tumor are discovered through imaging with contrast media. After the nutrient blood vessels are found, some chemotherapy drugs or some tumor-killing drugs are injected through the nutrient blood vessels to kill the tumor and reduce local symptoms. Therefore, interventional treatment mainly involves the search for some nutrient blood vessels, and then tumor control is carried out through some embolization of the nutrient blood vessels or injection of relevant chemotherapy drugs. Therefore, its method is an effective method, which is normally applicable to patients with older age, multiple lesions and severe local symptoms. After interventional therapy, the tumor shrinks, reduces the patient's symptoms, improves the patient's quality of life, and prolongs life. Experts suggest that there are three normal methods for interventional therapy. One is to take a certain contrast agent orally. The second is to find the nutrient vessels of the tumor by local angiography through interventional methods and block the nutrient vessels through gelatin sponge microspheres or some TACE to reduce the blood supply of the lesion site. The third is to reduce the local tumor through invasive arterial intervention, insertion of a catheter, and then injection of contrast medium.
