Morphologic and genomic changes of thyroid cancer cell lines exposed to conditions of simulated microgravity.

Microgravity in space impacts human health. In particular, thyroid cancer, which has a high incidence rate, has been the subject of numerous studies with respect to microgravity. However, most studies have focused on Western follicular thyroid cancer cell lines, while data regarding the effects of microgravity on Asian cell lines are lacking.

Intraoperative pathologic evaluation of central compartment lymph nodes in patients undergoing lobectomy for unilateral papillary thyroid carcinoma.

Background/objective: Although papillary thyroid carcinoma (PTC) has an excellent prognosis, it can cause central lymph node metastasis (CLNM) which can increase local recurrence. Intraoperative pathologic evaluation (IOPE) can provide evidence regarding CLNM and help surgeons determine the appropriate surgical approach. The aim of this study was to evaluate the efficacy of IOPE and to determine risk factors associated with CLNM in unilateral PTC without preoperative clinical evidence of CLNM.

A prospective randomized controlled trial to assess the efficacy and safety of prophylactic central compartment lymph node dissection in papillary thyroid carcinoma.

Background: The efficacy of prophylactic central compartment lymph node dissection for papillary thyroid carcinoma remains controversial. We performed a randomized controlled trial to evaluate the efficacy and safety of prophylactic central compartment lymph node dissection in patients with papillary thyroid carcinoma.

Methods: In this parallel-group randomized controlled trial, we assessed 101 patients aged 20 to 70 years with small/noninvasive papillary thyroid carcinoma and no clinical metastases or history of cervical surgery/radiation exposure.

Robotic Completion Thyroidectomy via the Bilateral Axillo-Breast Approach.

Background: Bilateral axillo-breast approach (BABA) robotic thyroidectomy has been successfully performed for thyroid cancer patients with excellent cosmetic results. Completion thyroidectomy is sometimes necessary after thyroid lobectomy, and whether it has a higher complication rate than the primary operation due to the presence of adhesions remains controversial. The aim of this study was to evaluate surgical outcomes, including operation time and postoperative complications, in patients who underwent BABA robotic completion thyroidectomy.

Efficacy of Intraoperative Neuromonitoring in Reoperation for Recurrent Thyroid Cancer Patients.

Background: The use of intraoperative neuromonitoring (IONM) in thyroid surgery to preserve recurrent laryngeal nerve (RLN) function has been widely accepted. We aimed to evaluate the usefulness of IONM in reoperation for recurrent thyroid cancer patients to help identify the RLN and prevent vocal cord palsy (VCP).

Methods: We analyzed 121 consecutive patients (with IONM group, 48 patients; without IONM group, 73 patients) who underwent reoperation for recurrent thyroid cancer after total thyroidectomy from January 2009 to March 2019 in our institution without VCP due to previous operations.

Initial Experience of Endoscopic Thyroidectomy Using Bilateral Axillary Breast and Transoral Vestibular Approach in Georgia.

Purpose: Remote access thyroid surgery using a bilateral axillary breast approach (BABA) or a transoral endoscopic thyroidectomy vestibular approach (TOETVA) are increasingly performed worldwide. In the Caucasus, these methods were first applied in the Republic of Georgia. This study compares these two methods of endoscopic thyroid surgery performed on patients in a tertiary hospital in Tbilisi, Georgia.

Comparison between the 4K ultra-high definition (UHD) and high definition (HD) endoscopic systems for transoral endoscopic thyroidectomy.

Background: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is the most recently introduced method of minimally invasive thyroid surgery. To our knowledge, no studies have compared TOETVA outcomes using different laparoscopic systems. This study compared outcomes of TOETVA using conventional high definition (HD) and ultra-high definition (UHD) equipment.
