Remarkable response in 2 cases of Advanced Poorly Differentiated Thyroid Carcinoma with liposomal doxorubicin plus cisplatin.

Background: Poorly Differentiated Thyroid Carcinoma (PDTC), especially advanced PDTC, is an aggressive disease and displays a much poorer prognosis compared with well differentiated thyroid carcinoma. Surgery is the recommended treatment in the early stage of PDTC, however, no effective treatment modalities are currently available for advanced PDTCMethods: Two advanced PDTC patients with no radioiodine uptake adopted a cytotoxic chemotherapy with liposomal doxorubicin (35 mg/m(2), day 1) plus cisplatin (75 mg/m(2), day1-3) every 3 weeks. Computer tomography (CT) was performed after 6 cycles (case 1) or 5 cycles (case 2) of chemotherapy

Results: Our patients achieved remarkable response with one a Complete Remission (CR) and the other a very good Partial Remission (PR)Conclusion: Our findings indicate that liposomal doxorubicin-based chemotherapy regimens might produce response in PDTC patients, and improve their overall survival and quality of life. Hence we believe this result is very important for oncologists in treating PDTC.
