Abstract
Background and purposeAnaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy. The potential for pathologic misclassification complicates interpretation of published data. One standard treatment option for locoregionally advanced disease is weekly low-dose doxorubicin with concurrent radiation therapy, and was previously developed at our institution. We evaluated our more recent experience with this approach, which included pathologic confirmation of all cases. Materials and methodsA retrospective review was performed on patients identified through the Memorial Sloan-Kettering Cancer Center (MSKCC) Cancer Database. Inclusion criteria: pathologically confirmed ATC; locoregional disease encompassable within a radiation portal; treatment with curative intent at MSKCC with planned weekly doxorubicin (10mg/m2) and concurrent radiation. Principle outcomes assessed were locoregional progression-free survival (LR-PFS) and overall survival (OS). ResultsThirty-seven patients were included. Median radiotherapy dose was 57.6Gy, and was ⩾50Gy in 29 (78%), administered through hyperfractionated or once-daily schedules. One-year outcomes were LR-PFS, 45%; OS, 28%. ConclusionThe prognosis of patients with ATC remains grim and our current results appear inferior to those reported previously by our institution. More accurate histologic diagnoses and patient selection in the present series compared to the prior one may be responsible in part. Better therapy is desperately needed for this aggressive disease.
