Gastroduodenal ulceration after selective internal radiation therapy of liver tumor.
Image-guided interstitial brachytherapy is used for the treatment of primary and secondary liver tumors. Millions of nonbiodegradable yttrium-90 (90Y)-imprinted microspheres with a diameter of 29– 35 μmare selectively infused by a catheter into the branch of the hepatic artery supplying the tumor. Thereby, a radiation dose of 30–60Gy can be applied to the tumor tissue. 90Y is a beta-emitter wit...
متن کاملSelective internal radiation therapy for liver tumours.
Primary and secondary liver malignancies are common and associated with a poor prognosis. Surgical resection is the treatment of choice; however, many patients have unresectable disease. In these cases, several liver directed therapies are available, including selective internal radiation therapy (SIRT). SIRT is a multidisciplinary treatment involving nuclear medicine, interventional radiology ...
متن کاملDiagnosis of Liver Tumor Using 3D Segmentation Method for Selective Internal Radiation Therapy
This paper introduces 3-D liver segmentation method for selective internal radiation treatment as the treatment for liver tumors. In treatment of liver cancer, delivering maximum radiation dose to the tumor and minimum toxicity to the surrounding healthy tissue is of great difficult in clinical practice. This can be eliminated by 3-D segmentation method for accurate calculation of functional tu...
متن کاملGastroduodenal ulceration following liver radioembolization with yttrium-90.
Radioembolization or selective internal radiation therapy (SIRT) with yttrium-90 (90Y) resin microspheres is an effective locoregional treatment for unresectable primary and metastatic malignancies of the liver [1]. SIRT is a straightforward method of delivering microspheres containing 90Y (a high-energy β-emitting radioisotope) to the microvasculature of malignancies whilst sparing the normal ...
متن کاملSelective Internal Radiation Therapy (SIRT) as Conversion Therapy for Unresectable Primary Liver Malignancies.
BACKGROUND Many patients with primary liver cancers are not candidates for surgery, and systemic therapies are seldom effective. Selective internal radiation therapy (SIRT) has been shown to obtain partial and even complete response in unresectable primary tumors. As a "side effect", SIRT can induce contra-lateral liver hypertrophy. Tumor response to SIRT can be sufficient to allow disengagemen...
