This study supports the role of miR-21 as an oncogene and a biomarker for breast cancer with its high expression in cancer tissues and its relationship with other prognostic factors and survival.

OBJECTIVES/HYPOTHESIS: Thermal injury to the recurrent laryngeal nerve (RLN) may not be visually apparent and may go unrecognized intraoperatively. This study aimed to investigate the heat thermal tolerance of RLN and evaluate the electrophysiologic correlates of electromyographic (EMG) signal change during an acute RLN heat damage. STUDY DESIGN: Prospective porcine model with continuous intraoperative neuromonitoring (CIONM). METHODS: Ten pigs (20 RLNs) undergoing CIONM had their EMG tracings r

BACKGROUND: The purpose of this study was to evaluate electromyography (EMG) amplitude and latency changes during tube dislocation in monitored thyroid surgery, which may be observed without recurrent laryngeal nerve injury. METHODS: Duroc-Landrace piglets were intubated with the TriVantage EMG tube. We measured EMG changes during both upward and downward tube dislocation (10-20 mm) and rotation (45-90°) with continuous neuromonitoring. RESULTS: The EMG amplitude varied significantly with induce

Radiogenomics investigates the relationship between imaging phenotypes and genetic expression. Breast cancer is a heterogeneous disease that manifests complex genetic changes and various prognosis and treatment response. We investigate the value of machine learning approaches to radiogenomics using low-dose perfusion computed tomography (CT) to predict prognostic biomarkers and molecular subtypes of invasive breast cancer. This prospective study enrolled a total of 723 cases involving 241 patien

BACKGROUND: Although several recent studies have demonstrated the feasibility and safety of robotic adrenalectomy, it is unknown whether this procedure has advantages over the traditional laparoscopic approach. This study compared our initial experience using the da Vinci-S® robotic surgical system during laparoscopic adrenalectomy with our experience with traditional laparoscopic adrenalectomy. METHODS: From October 2009 to May 2012, 23 consecutive patients (13 women, 10 men) underwent laparosc

Collagen is one of numerous components of the cellular microenvironment. To date, the association between the microenvironment and tumorigenesis of malignant breast cancer remains elusive. Therefore, the aim of the present study was to investigate the potential role of a secretory protein of stromal cells, type I collagen, in the development of the aggressive characteristics of breast cancer cells. MDA-MB231 and MCF7 breast cancer cell lines were maintained in cultured media of normal human derm

Robotic thyroidectomy using BABA may be a technically feasible and safe procedure comparable to conventional open surgery especially in node-negative patients.

Robotic transoral periosteal thyroidectomy provides superior access to the thyroid and central neck compartment. Transoral thyroidectomy using four ports is a feasible and safe method.

PURPOSE: Endoscopic breast surgery for patients with breast cancer was introduced for its superior cosmetic outcomes; it was initially studied in the field of breast-conserving surgery and, more recently, in robotic-assisted nipple-sparing mastectomy (NSM). The main purpose of this study was to investigate the feasibility and safety of endoscopic NSM (E-NSM) in patients with breast cancer by comparing E-NSM and conventional NSM (C-NSM). METHODS: Between May 2017 and October 2020, we retrieved th

Transoral periosteal thyroidectomy could be feasible and safe.

BACKGROUND: Recurrent laryngeal nerve (RLN) palsy is the most serious complication after thyroidectomy. However, little is known about the degree of traction injury that causes loss of signal. The purpose of this study was to evaluate traction injuries in the swine RLN using continuous intraoperative neuromonitoring (IONM) and determine the traction power that results in loss of signal. METHODS: Thirteen swine underwent traction injury to the RLNs with continuous IONM, and stress-strain curves w

BACKGROUND: This study evaluates the efficacy of intraoperative neuromonitoring (IONM) on voice performance in robotic thyroidectomy. MATERIALS AND METHODS: The study was based on a prospective randomized series. Between June 2011 to September 2012, 50 patients with thyroid cancer who underwent robotic thyroidectomy were enrolled. The IONM and non-IONM groups consisted of 25 patients each. Voice Handicap Index (VHI), voice range profile (VRP), and laryngoscopy were used to assess voice function
