3D Printed Template CT-Guided 125I Seed Implantation In The Treatment Of A Patient With Giant Type A Thymoma: A Case Report

Background: Thymoma, as a malignant tumor with low incidence, is still recommended to be treated with surgery. For middle and advanced patients who can not be treated with surgery, it is recommended to use preoperative radiochemotherapy or chemotherapy. After the tumor regressed, the feasibility of surgical resection will be evaluated. As a new technique developed in recent years, 3D template CT-guided 125I seed implantation has achieved effective results in the treatment of a variety of solid tumors. Case presentation: We report a case of locally advanced giant thymoma (more than 10 cm) who received 3D template CT-guided 125I seed implantation and achieved clinical complete remission. Conclusions: It suggested that radioactive particle implantation may be a new and effective method for the nonoperative treatments of thymoma.
