RESUMO
@#With the increasing popularity of chest spiral CT screening, the detection rate of lung cancer in China is increasing. According to the characteristics of lung cancer in China and the progress of lung cancer researches at home and abroad, Chinese Medical Association guidelines for clinical diagnosis and treatment of lung cancer are updated once a year. It is of great guiding significance to standardize and improve the clinical diagnosis and treatment of lung cancer for thoracic surgeons. The surgical diagnosis and treatment of lung cancer in the guidelines mainly include: (1) surgical treatment of stage Ⅰ-Ⅱ non-small cell lung cancer (NSCLC); (2) surgical treatment of resectable stage Ⅲ NSCLC; (3) surgical treatment of multiple primary lung cancer; and (4) surgical treatment of locally resectable small cell lung cancer. Based on the Chinese Medical Association guidelines for clinical diagnosis and treatment of lung cancer (2019 edition), this paper interprets the hot issues related to the surgical treatment of lung cancer.
RESUMO
Objective To investigate the expression of phosphorylated RB (pRB) in the invasion front of papillary thyroid carcinoma and the clinical pathological implications. Methods Immunohistochemistry was ap-plied in analyzing pRB expression feature and the clinical pathological implications in a total of 82 patients who underwent total or subtotal thyroidectomy and neck lymph node dissection for papillary thyroid carcinoma. Results The displacement of pRB proteins from the nucleus to the cytoplasm was observed in the invasive front of papil-lary thyroid carcinoma , which was an independent predictor of lymph node metastasis in papillary thyroid carci-noma. Conclusion Nuclear-cytoplasmic transport of pRB in the invasive front was an independent predictor of lymph node metastasis in papillary thyroid carcinoma.
