ABSTRACT
Objective:To investigate the effectiveness, safety, and advantages of modified radical neck dissection by gasless unilateral axillary approach (GUA-MRND) in the surgical management of selected patients with papillary thyroid cancer.Methods:We retrospectively analyzed patients with papillary thyroid cancer who underwent GUA-MRND (endoscopic group, n=16) versus unilateral open modified radical neck dissection (MRND) (open group, n=32) during the period from Jan. 2019 to Jun. 2021, including the differences in surgical efficiency, complication rate, and incisional satisfaction.Results:Compared MRND with GUA-MRND, the patients were younger ( P<0.05) , operative time and postoperative drainage anterior ( P<0.01) were slightly inferior in the latter, but it had obvious advantages in cervical swallowing discomfort and incision satisfaction evaluation ( P<0.05) . There was no significant difference in the incidence of temporary recurrent laryngeal nerve injury, intraoperative and postoperative bleeding, hematoma, infection, lymphatic or chylous leakage and supraclavicular numbness after surgery ( P>0.05) . The number of dissected lymph nodes in area II in the GUA-MRND was lower ( P<0.05) , but it was significantly higher ( P<0.01) in area III. And the average regional cleaning efficiency in the GUA-MRND was level Ⅲ (35.5%) , level Ⅵ (28.59%) , level Ⅳ (23.21%) , level Ⅱ (7.18%) and level Ⅴ (7.12%) , suggested that GUA-MRND had higher efficacy for level III, level Ⅵ and Level IV. Conclusion:GUA-MRND is safe, effective, and has high cosmetic satisfaction in the treatment of selected patients with lateral cervical lymph node metastases from papillary thyroid cancer.
ABSTRACT
Objective:To compare the postoperative neck pain, discomfort and swallowing difficulty in patients with papillary thyroid cancer (PTC) after conventional open thyroidectomy (COT) and endoscopic thyroidectomy using the gasless unilateral axillary approach (ET-UA) .Methods:The study included 117 female patients with PTC who underwent unilateral thyroid lobectomy plus central neck dissection using COT ( n=68) or ET-UA ( n=48) performed by the same experienced surgeon. Subjective neck pain, discomfort and swallowing alterations were assessed by questionnaire 3 day and 6 months postoperatively. Surgical scar and cosmetic satisfaction evaluation were implemented 6 months postoperatively. SPSS 20.0 was used for statistical analysis, the rate or composition ratio was compared by the χ2 test or the exact probability method, and the significance test of the difference in sample means was tested by analysis of variance. Results:Three days after surgery, the neck pain scores of COT group and ET-UA group were (2.13±1.07) and (2.31±1.07) ( P=0.368) ; the neck injury index was (5.13±3.02) and (5.31±3.00) ( P=0.748) ; the dysphagia index was 5 (0.49±3.47) and (3.77±2.96) ( P=0.006) . At 6 months postoperatively, the neck pain scores in COT group and ET-UA group group were (0.52±0.61) and (0.60±0.74) ( P=0.510) ; the neck injury index was (2.10±1.71) and (2.38±2.35) ( P=0.467) ; the dysphagia index was (2.68±2.36) and (1.81±1.83) ( P=0.034) , respectively. Conclusion:Our preliminary study shows that there is no significant differences in postoperative neck pain or discomfort between COT groups and ET-UA group, whereas the impact of ET-UA on swallow function is relatively small than COT.
ABSTRACT
In recent years,the abnormal expression of microRNA-21 (miR-21) in head and neck carcinoma have been found in many studies,which may be closely related to the genesis and development of thyroid carcinoma,nasopharyngeal carcinoma,laryngocarcinoma and oral carcinoma,etc.MiR-21 may also be valuable for the clinical diagnosis,treatment and prognosis of head and neck carcinoma.
ABSTRACT
In recent years,the abnormal expressions of BRAF,Runx2,Runx3 and S100A4 genes in thyroid papillary carcinoma have been found in many studies.The abnomal expressions of those genes are closely related to the tumor invasion,lymph node metastasis,mulifocality of thyroid papillary carcinoma,which may be valuable in clinical diagnosis and treatment.
