Differentiated thyroid cancer in the elderly: Our experience

Introduction: The objective of this retrospective study was to investigate clinical and pathologic characteristics of differentiated thyroid cancer in elderly patients and to evaluate the results of surgical treatment in this age group. Methods: The clinical records of patients who underwent total thyroidectomy between 2002 and 2012 with histopathological diagnosis of differentiated thyroid cancer were analyzed. Patients were divided into two groups: those 65 years old or older were included in group A (101), those younger in group B (354). Results: The mean surgical time was 100.9 +/- 30.5 min in group A and 100.7 +/- 27.6 in B. Postoperative stay was significantly longer in group A (2.8 +/- 1.5 days vs 2.4 +/- 0.7; p < 0.01). Classic papillary carcinoma was more frequent in group B, whereas follicular variant of papillary carcinoma and tall cell carcinoma in A. In group B node metastases were nearly twice. In Group A transient hypoparathyroidism occurred in 25 patients (24.8%), permanent hypoparathyroidism in 4 (4%), hematoma in 6 (5.9%), recurrent nerve palsy in 2 (2%), and wound infection in 2 (2%). In group B transient and permanent hypoparathyroidism occurred in 48 and 7 patients respectively (13.6% and 2%), hematoma in 4 (1.1%), recurrent nerve palsy in 5 (1.4%), and wound infection in 1 (0.3%). Conclusions: Differentiated thyroid carcinoma is more aggressive in elderly patients for biological causes connected to age and to histotype but also for the diagnostic delay. Thyroid surgery in elderly patients is safe when the procedure is carried out by experienced staff. Total thyroidectomy is the surgical operation of choice. (C) 2014 Surgical Associates Ltd.
