Feasibility of the enhanced neuromuscular blockade recovery protocol with selective use of sugammadex in thyroid surgery with intraoperative neuromonitoring.

BACKGROUND: To investigate feasibility of utilizing enhanced neuromuscular blocking agents with selective recovery protocol during thyroid surgery with intraoperative neuromonitoring (IONM). METHODS: Two-hundred and ninety patients were randomized into two groups: group A 0.3 mg/kg rocuronium and group B 0.6 mg/kg. Sugammadex 2 mg/kg was injected if needed followed initial vagal stimulation (V0). Electromyography signals from vagus and recurrent laryngeal nerves before and after resection were recorded as V1, V2, R1, and R2. RESULTS: In group B, 30 patients (20.7%) had V0 signals <100 µV, compared to 9 (6.2%) in group A. After sugammadex administration, 144 patients (99.3%) in both groups achieved positive V1 signals. Group B demonstrated a shorter surgical time from rocuronium injection to V2 stimulation compared to group A, accompanied by a significantly lower incidence of intraoperative body movement (0 vs. 16 patients). CONCLUSIONS: 0.6 mg/kg rocuronium with selective use 2 mg/kg sugammadex for IONM in thyroid surgery can meet both anesthesia and surgery demands.

Neoadjuvant famitinib and camrelizumab, a new combined therapy allowing surgical resection of the primary site for anaplastic thyroid carcinoma.

BACKGROUND: Anaplastic thyroid cancer (ATC) is considered the most lethal thyroid cancer, with an overall 5-year survival rate below 10%. The FDA approved a BRAF/MEK inhibitor combination for the treatment of patients with BRAF-mutated ATC. However, effective therapeutic options for patients with wild-type BRAF are lacking. CASE: In our phase II study, patients having advanced/metastatic solid ATCs were treated with famitinib and camrelizumab, a combination therapy involving a multi-targeted kinase inhibitor and an anti-PD-1 antibody. We report a case of a patient with locally advanced unresectable ATC who underwent this combination therapy, allowing us to perform complete surgical resection followed by post-operative radiation therapy. CONCLISION: To the best of our knowledge, this is the first report describing the use of famitinib and camrelizumab as a neoadjuvant treatment for ATC with wild-type BRAF. Clinical trial for a novel neoadjuvant approach for ATC are currently open for enrollment.

Multifocal papillary thyroid cancer in children and adolescents: 12-year experience in a single center.

BACKGROUND: Thyroid cancer is the most common endocrine malignant disease in children and adolescents. There is a trend of more conservative strategies including lobectomy and less radioactive iodine therapy (RAI) in multifocal papillary thyroid cancer (PTC) for its good survival outcome. The aim of our study was to define long-time outcome of a large cohort of multifocal PTC patients less than 20 years old treated at our institution. METHODS: Data were collected from 276 cases who were initially diagnosis of PTC under the age of 20 from January 2006 to December 2015 at Fudan University Shanghai Cancer Center. All patients received total/near total thyroidectomy or lobectomy. Therapeutic central-compartment (level VI) and lateral neck lymph node dissection performed for patients with clinically involved neck nodes. RAI therapy used in selected patients. No patients received chemotherapy or kinase inhibitor therapy. Thyroid-stimulating hormone (TSH) suppression therapy was performed in all patients for at least 5 years. RESULTS: Ninety among 276 were multifocal PTC patients and included in this study. The median follow-up time was 54.28 months, ranging from 6.10 to 141.27 months. Fifteen patients had tumor recurrence during the follow-up. On Kaplan-Meier survival curves, lymphovascular invasion and extrathyroidal extension was associated with a decline in recurrence-free survival. However, there was no difference in recurrence-free survival curves in patients no matter which treatment they had received, either lobectomy or total thyroidectomy, RAI or not. CONCLUSIONS: More conservative strategies including lobectomy and less RAI in multifocal PTC among children and adolescents are safe and effective.
