Comparative Study of Transaxillary Robotic Thyroidectomy With MRND Versus Conventional Open Surgery in N1b PTC
A study testing robotic-assisted surgery and Open Surgery in people with Papillary Thyroid Carcinoma and Lymphatic Metastasis, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.
Trial summary
Thyroid cancer is one of the most common malignant tumors in women, ranking seventh in the United States and fourth in China. Papillary thyroid carcinoma is the most common pathological type (about 85% to 90% of thyroid cancers), and lateral cervical lymph node metastasis can reach 0.6-37.5% at diagnosis.

About this study
Official title: Comparative Study of Transaxillary Robotic Thyroidectomy With Modified Radical Neck Dissection Versus Conventional Open Surgery in Patients With Papillary Thyroid Carcinoma and Lateral Neck Node Metastases: a Prospective Multicenter Randomized Controlled Study
Thyroid cancer is one of the most common malignant tumors in women, ranking seventh in the United States and fourth in China. Papillary thyroid carcinoma is the most common pathological type (about 85% to 90% of thyroid cancers), and lateral cervical lymph node metastasis can reach 0.6-37.5% at diagnosis. For papillary thyroid cancer with lateral cervical lymph node metastasis, the 2015 ATA Guidelines in the United States recommend surgical resection and neck lymph node dissection as the primary treatment. Traditional cervical lymph node dissection often leaves obvious scars in the neck, which seriously affects the postoperative quality of life of patients. The previous studies have shown that endoscopy-assisted surgery with external cervical approach can achieve oncologic effects similar to traditional open surgery in the treatment of N1b papillary thyroid cancer, and can obtain better aesthetic results. However, endoscopic surgery still has some shortcomings, such as poor exposure of some surgical areas and difficult operation. Since November 2016, the investigators tried to apply modified transaxillary robotic-assisted surgery technology to the treatment of thyroid papillary carcinoma in China. The preliminary study included 30 patients, and the results showed that robot-assisted surgery via combined transaxillary-retroaural approach in the treatment of N1b papillary thyroid carcinoma achieved a good oncologic effect (5-year overall survival rate was 100.0%). As the surgical techniques improved, now the investigators can complete robotic-assisted lateral neck lymph node dissection via single-incision transaxillary approach. However, there is still a lack of high-quality evidence on the long-term oncologic outcome and quality of life of this procedure. In this study, a prospective, multi-center, randomized controlled study was conducted to compare the safety, long-term oncologic outcomes and postoperative quality of life of the robot-assisted surgery via single-incision transaxillary approach and open surgery in the treatment of N1b papillary thyroid cancer, which may provide an alternative for the patients with N1b papillary thyroid cancer.

the disease-free survival rate
The 5-year survival rate without a functional, structural, or biological event
Measured: 60 months
Postoperative quality of life:36-Item Short-Form Survey
The quality of life is assessed by 36-Item Short-Form Survey (SF-36) 1 year after surgery, and the differences in physical and physiological dimensions between the two groups were compared. The higher scores mean a better outcome.
Measured: 12 months
Secondary outcomes (7)

Measured: 60 months
The dynamic change trend of shoulder function
Shoulder function is assessed using arm abduction test (0-5) to explore the dynamic change. The higher scores mean a better outcome.

The dynamic change trend of the postoperative quality of life
The postoperative quality of life is assessed using 36-Item Short-Form Survey to explore the dynamic change. The higher scores mean a better outcome.
Measured: 60 months
The dynamic change of swallowing function
Swallowing function is assessed using Swallowing Impairment Index 6 (0-24) to explore the dynamic change. The higher scores mean a worse outcome.

The dynamic change trend of aesthetic satisfaction
Aesthetic satisfaction is assessed using verbal response scale (0-10) to explore the dynamic change. The higher scores mean a better outcome.
Measured: 60 months
The dynamic change trend of voice function
Voice function is assessed using Voice Handicap Index 10 (0-40) to explore the dynamic change. The higher scores mean a worse outcome.
Measured: 60 months
