Can doxorubicin be used for thyroid cancer?
Adjuvant chemotherapy is not useful to manage differentiated thyroid cancer. Doxorubicin may be a radiation sensitizer in some thyroid tumors and has been considered for locally advanced disease while EBRT is being administered. Since anaplastic forms are not receptive to RAI, there have been partial remissions with use of chemotherapy. Though doxorubicin is the most common chemotherapeutic for thyroid cancer, monotherapy results are poor, and only 17% of cases achieve partial remission. However, when doxorubicin is combined with cisplatin, there is higher therapeutic activity and more complete responses, with 30% of patients responding successfully.
