Abstract

Objective: To describe the clinical and paraclinical characteristics of pediatric thyroid cancer patients undergoing transoral endoscopic thyroidectomy (TOETVA) at Hanoi University of Medicine Hospital. Method: A cross-sectional study was conducted on 15 patients at the Oncology Center, Hanoi University of Medicine Hospital from February 2020 to September 2024. Results: The average age in the study group was 16.2±2.1 (11-18) years, with 13 female patients (86.7%) and 2 male patients (13.3%). Twelve patients (80%) underwent thyroid lobectomy with central neck dissection on the same side, and 3 patients (20%) had total thyroidectomy with bilateral central neck dissection. The average number of lymph nodes retrieved and the number of metastatic nodes were 8.3±5.4 and 2.9±3.5, respectively, with an occult lymph node metastasis rate of 53.3%. The average tumor size in the study group and the metastatic node group were 11.7±6.2 mm and 13±6.2 mm, respectively. Two patients (13.3%) had multifocal thyroid cancer. Postoperative histopathology showed that 14 patients (93.3%) had conventional papillary thyroid carcinoma, 1 patient (6.7%) had diffuse sclerosing variant papillary thyroid carcinoma, and 20% had concomitant thyroiditis. Conclusion: Pediatric thyroid cancer treated with transoral endoscopic thyroidectomy is commonly detected in older children, with characteristics such as large tumor size, multifocality, and a high rate of occult lymph node metastasis.
