title: New operative strategy in the treatment of metastasizing medullary carcinoma of the thyroid.
abstract: Medullary carcinoma of the thyroid (MTC) is exceptional in that the hormone calcitonin produced by the tumor cells represents a specific and sensitive tumor marker. Careful screening by serial calcitonin determinations following pentagastrin stimulation allows for the early detection of metastatic disease. We have adopted a method of meticulous modified radical neck dissection to eradicate persistent or recurrent MCT in 11 patients treated over a 15-month period. This surgical approach resulted in potentially curative treatment in two patients. Effective tumor reduction was achieved in another seven. Two patients have persistent or progressive disease despite maximum efforts to eradicate malignant tissue. Follow-up is presently incomplete in one patient. Postoperative complications included recurrent nerve paralysis (n = 3), hypoparathyroidism (n = 2), muscular weakness (n = 2) and Horner's syndrome (n = 3). The majority of nervous complications improved spontaneously. It is concluded that the adopted method of meticulous modified radical neck dissection offers the chance of cure to some patients and results in the removal of substantial tumor mass in the majority of others. Postoperative problems are mostly temporary and are deemed acceptable.
