Trojan remember is the history of ancient Greece a famous battle, and now the treatment of liver cancer, there have been similar to the Trojan horse of new technologies. Taipei Veterans General Hospital introduced radiotherapy in vivo, will have millions of radioactive yttrium 90 microspheres directly to the liver itself, from the inside out to release a high radiation dose to kill cancer cells.
Taipei Veterans General Hospital last year, the introduction of the "Y-90 microspheres - selective body radiotherapy," admitted a total of 41 liver cancer and other terminal cancer patients with metastasis to the liver, a good therapeutic effect. "This from the inside out of the end of radiotherapy in patients with liver cancer has provided the last chance of survival!" Taipei Veterans General Hospital Department of Radiology, said Dr. Rheun-Chuan Lee, in accordance with the present treatment, in patients with terminal liver cancer is no cure, and the radioactive element yttrium 90 microspheres provide a new hope.
However, this new medication therapy alone have to spend more than 40 million, pre-and postoperative examination of the patient have at their own expense, all medical expenses more than 600,000 yuan.
Rheun-Chuan Lee pointed out that the radioactive element Yttrium-90 containing microspheres, the diameter is very small, only about one-third of the hair, by the way angiography in the liver, from the groin into the hepatic artery within the liver directly to the microspheres blood vessels inside tumors, and then gradually released within two weeks of high-dose radiation, to kill liver tumors.
Rheun-Chuan Lee explained that in addition to Y-90 microspheres, the radiation from all the other outside, the radiation from the in vitro into the human body, therefore, can not be too high dose, not to harm normal tissue, and the microspheres is from the inside out , in addition to high accuracy, the radiation dose is also higher, at around the other two to three times the radiation.
Trojan horse as the same way the use of angiography, Y-90 microspheres was sent after the hepatic artery, it will take the initiative to look for cancer cells. Tumor blood vessels as a result of the flow near the larger, 90-yttrium microspheres target, you enter the tumor, emit radiation to kill tumor lines.
Rheun-Chuan Lee pointed out that the current accepted treatment of patients with Y-90 are mostly due to the failure of multi-line chemotherapy or other treatment of patients with terminal liver cancer invalid, clinical showed that after two months follow-up found that 41 patients, about tumor shrinkage or five well-controlled.
As to whether the Y-90 microspheres in the treatment of other cancers do? The answer is no. Linked to other organs because the blood vessels, so can not use this type of radiation "
