Long-Term Remission in a Case of Anaplastic Thyroid Carcinoma following Local Irradiation and High-Dose Chemotherapy with Autologous Peripheral Blood Stem Cell Transplantation

Anaplastic thyroid carcinoma (ATC) is a tumor with bad prognosis and long-term survival is very low. However, appropriate combinations of chemotherapy, surgery, and radition have been reported to potentially improve the treatment results for ATC. We describe a case of refractory ATC successfully treated with high-dose chemotherapy (HDC) followed by autologous peripheral blood stem cell transplantation (auto-PBSCT). There has not been any evidence of recurrence for 10 years after auto-PBSCT. To the best of our knowledge, this is the first case of ATC that has been followed up for a long-term period after HDC with auto-PBSCT. This case suggests that intensive therapeutic approach such as HDC with auto-PBSCT may be useful.
