Clinical study of endoscopic surgery through thoraco mammary approach in treatment of thyroid papillary carcinoma / 中华内分泌外科杂志

ABSTRACT

Objective:To investigate the effect of endoscopic thyroidectomy through breast milk approach in patients with papillary thyroid carcinoma and its influence on Wnt and integrin signaling pathways.Methods:A total of 136 patients diagnosed with papillary thyroid carcinoma in our hospital from Jul. 2018 to Mar. 2020 were selected and were hospitalized for surgical treatment. According to different surgical procedures, they were divided into a study group (68 cases) and a control group (68 cases) . The control group was treated with open thyroidectomy and the study group was treated with thoracoscopic thyroidectomy. The two groups were compared in terms of immune function [CD4+, CD8+ and CD4+/CD8+], and pain index [PGE2, IL-6, Cor and VAS score]. RT-PCR method was used to detect WNT1, β-catenin, GSK3β and integrin Signal pathway before and after surgery.Results:Three days after operation, compared with the control group, the study group had significantly higher CD4+ and CD4+/CD8+ levels [ (27.62±2.52) vs (24.63±2.67) , (0.66±0.18) vs (0.52±0.13) ], while the CD8+ level was significantly lower [ (41.62±3.54) vs (45.62±3.63) ] ( P<0.001) ; PGE2, IL-6, Cor, VAS of the study group were significantly lower than the control group [ (48.54±9.86) vs (57.21±8.12) , (5.13±0.71) vs (6.99±0.95) , (511.23±67.52) vs (633.12±71.47) , (1.26±0.56) vs (3.99±2.06) ] ( P<0.001) ; WNT1, β-catenin, GSK3β, integrin β1, FAK, Ras, and MAPK mRNA expression levels in the study group were significantly lower than those of the control group[ (1.79±0.15) vs (2.85±0.25) , (1.94±0.15) vs (2.64±0.24) , (2.13±0.19) vs (2.97±0.28) , (1.95±0.17) vs (2.58± 0.23) , (2.15±0.16) vs (2.87±0.22) , (1.95±0.18) vs (2.91±0.27) , (1.89±0.12) vs (2.87±0.31) ] ( P<0.001) . Conclusion:Endoscopic thyroidectomy through thoracolumbar approach can effectively reduce postoperative pain in patients with papillary thyroid cancer, have a smaller impact on immune function, and block the expression of Wnt and integrin signaling pathways to reduce tumor metastasis risk.
