Abstract

Objective: To evaluate the clinical and paraclinical characteristics of patients with bilateral thyroid cancer undergoing transoral endoscopic thyroidectomy vestibular approach (TOETVA) at Hanoi Medical University Hospital. Subjects and Methods: A prospective study was conducted on 30 eligible patients who underwent TOETVA at the Oncology Center, Hanoi Medical University Hospital, from January 2020 to July 2024. Clinical, paraclinical, and surgical characteristics were recorded. Results: A total of 29 female patients and 1 male patient were included in the study. The mean age was 33.1 ± 8.6 years (range: 16–51 years). The mean number of nodules was 1.76 ± 1.15 in the left thyroid lobe, 1.71 ± 0.99 in the right lobe, and 3.75 ± 1.39 for both lobes combined. Multifocality was observed in 14 patients (46.7%) in the left lobe, 17 patients (56.7%) in the right lobe, and 8 patients (26.7%) in both lobes. The mean size of the largest tumor in each lobe was 6.56 ± 5.11 mm in the left lobe and 5.78 ± 3.91 mm in the right lobe. All patients underwent total thyroidectomy with prophylactic bilateral central neck dissection. Postoperative histopathological examination confirmed the diagnosis of papillary thyroid carcinoma in all patients (100%). Central neck lymph node metastasis was detected in 14 patients (46.7%). Extrathyroidal extension was detected in 7 patients (23.3%). Conclusion: Bilateral thyroid cancer had high prevalence of multifocality, cervical lymph node metastasis, and extrathyroidal extension.
