Abstract
Objective
In this study, we present our experience with aggressive surgical treatment in selected patients with anaplastic thyroid cancer with extrathyroidal extension.
Study Design
Case series with chart review.
Setting
Tertiary care referral center.
Subjects and Methods
Retrospective chart review of all patients with anaplastic thyroid cancer surgically treated by the senior author from January 1998 to July 2012.
Results
A total of 38 cases of anaplastic thyroid cancer were treated (21 male and 17 female). The mean age was 64.5 years. Twenty-two patients were considered surgically unresectable (18 had distant metastases and 4 had extrathyroidal extension of cancer lateral to carotid arteries) and underwent biopsy with or without tracheostomy. The remaining 16 patients underwent surgical resection with curative intent. Fourteen of these patients underwent postoperative radiation therapy. None of these 16 patients developed local recurrence. Six developed distant metastasis at an average follow-up of 3.2 months, 1 died of an unrelated myocardial infarction at 3 months, 2 were lost to follow-up, and 7 remain disease free with an average follow-up of 4.8 years (range, 9 months to 8 years). Of those patients who underwent complete surgical resection followed by postoperative radiation, 7 of 14 (50%) are still alive, with a mean follow-up of 4.8 years.
Conclusion
Selected patients with anaplastic thyroid cancer with extrathyroidal extension (stage IVB) who show no distant metastases by computed tomography or positron emission tomography scans and who do not have tumor extending lateral to the carotid arteries are candidates for complete surgical resection.
