Clinical controversy and research thoughts on lymphadenectomy of gastric cancer / 中华胃肠外科杂志

Lymphadenectomy, as one of the controversial foci in clinic, is an extremely important part of radical surgery for gastric cancer. So far, the preliminary consensus has been reached on the scope and number of lymph node dissection, based on the etiological mechanism, disease progression, diagnosis and treatment prognosis of gastric cancer. At present, some clinical issues of lymphadenectomy in curative gastrectomy are still need to be addressed. Firstly, standardized procedure in lymph node dissection for gastric cancer is a prerequisite to decrease the incidence of postoperative complications and to improve the prognosis of gastric cancer patients. Furthermore, the plausible treatment strategy in perioperative phase is also deemed as the other key method to offer a benefit of survival rate for advanced stage patients after lymphadenectomy. Last but not least, the technologies for enhancement the prediction accuracy of lymph node metastasis preoperatively or intraoperatively should be worthy in-depth study.

Expression of C-MET in thyroid carcinoma with cervical lymph node metastases and its clinical significance / 中国普通外科杂志

Objective To investigate the expression of C-MET in papillary thyroid carcinoma(PTC) with (cervical) lymph node metastases, PTC without cervical lymph node metastases,follicular thyroid carcinoma and benign thyroid disease and the clinical significance. Methods The expression level of C-MET was examined by immunohistochemical analysis with C-MET monoclonal antibody in 62 cases of PTC with cervical lymph node metastases, 50 cases of PTC without cervical lymph node mestastases, 10 cases of follicular (thyroid) (carcinoma) and 30 cases of benign thyroid disease. Results PTC with cervical lymph node metastases (expressed) significantly greater level of C-MET than the other forms of thyroid carcinoma and benign thyroid disease(P
