Purpose : The author performed this study to find factors influencing the locoregional
recurrence in papillary thyroid carcinoma (PTC) with reference to the adequacy of initial
treatment.
Materials and Methods : Records of 13 patients who had received a surgical therapy
for locoregional recurrence of PTC at Pusan National University Hospital between
January 1993 and December 1996 were analyzed retrospectively.
Results : Twelve patients received the surgery after initial recurrence, while one
patient after the 2nd recurrence. At the time of initial surgical therapy, mean age of
patients was 51.4 years; 10 patients (76.9%) were female; PTC was documented pre- or
intraoperatively in 3 patients (23.1%); 1 patient (7.7%) had a combined preoperative
ultrasonography and computed tomography (CT) of the neck; mode of operation was
lobectomy in 9 patients (69.2%), total thyroidectomy in 2 patients (15.4%) and total
thyroidectomy with neck dissection in 2 patients (15.4%). At the time of second surgical
therapy, pattern of recurrence was regional in 7 patients (53.8%), combined locoregional
in 4 patients (30.8%) and local in 2 patient (15.4%); mode of operation was complete
thyroidectomy with neck dissection in 9 patients (69.2%), neck dissection in 2 patients
(15.4%), and local excision in 2 patients (15.4%). Final outcome of patients (mean
follow-up period, 2.8 years) was successful in 6 patients (46.2.%).
Conclusion : The data suggest that many cases of locoregional recurrence in PTC
occur as a consequence of poor initial therapy. A combined thyroid ultrasonography and
neck CT is recommended as a routine preoperative check during initial therapy. The
author believes that a total thyroidectomy is the surgical procedure of choice, which
facilitates postoperative 131I therapy.
