This is a prospective, multicenter, open label Phase II Clinical Trial. 30 advanced poorly differentiated thyroid carcinoma patients who were histopathologically confirmed inoperable were enrolled in this study.

Subjects will receive the treatment regimen as follow:

intravenous infusion of liposomal doxorubicin 35 mg/m2, d1; cisplatin 75 mg/m2, drip, total dose should be carried out on d1-3; once every 21days, for 6 cycles. Stop the treatment if the patients have progressed or intolerated to the toxicity. The primary endpoint is disease control rate(DCR), the secondary endpoint is overall survival (OS), progression-free survival (PFS), safety and quality of life assessment(QoL).
