[Central compartment reoperation for recurrent/persistent differentiated thyroid cancer]

Objective: To analyze the incidences of complications after central compartment reoperation for recurrent/persistent differentiated thyroid cancer, and to investigate the safety and feasiblity of central compartment reoperation. Methord: A total of 109 patients who underwent central compartment reoperation for recurrent/persistent differentiated thyroid cancer from January 1, 2011 to March 31, 2016 in Cancer Hospital, Chinese Academy of Medical Sciences was analysed retrospectively, and the incidences of reoperation-related complications were evaluated. Results: Among 109 patients, only 10 (9.2%) patients were treated initially in our hospital and remaining patients (90.8%) treated initially in the other hospitals. Surgical approaches for thyroid beds: 61 patients (56.0%) underwent supplemented total thyroidectomy, 3 patients (2.8%) for removal of recurrent thyroid cancer, 2 patients (1.8%) with supplemented total thyroidectomy and removal of recurrent thyroid cancer, and 12 cases (11.0%) had bilateral thyroid lobectomy. Central compartment lymph node dissection: 66 patients (60.6%) underwent bilateral central neck dissection, 40 patients (36.7%) with unilateral central neck dissection. A total of 16 patients (14.7%) had complications. Transient and permanent vocal fold paralysis developed in 9(8.3%) and 2(1.8 %) patients, respectively. Transient and permanent hypoparathyroidism occurred in 2(1.8%) patients and 11 patients (10.1%), respectively. Postoperative bleeding happened in 1 patient (0.9%). with follow-up from 7 to 61 month, median follow-up was 17.2 months. All patients survived, with recurrence in 3 (2.8%) patients. Conclusions: It seems the incidences of complications for thyroid carcinoma reoperation in central compartment is low for the experienced surgeon. The reoperation was safe and feasible.
