肺癌及早发现,早期诊断,早期治疗,对提高治愈率至关重要。随着分子生物学的发展,将肿瘤标志物的检测指标用于恶性肿瘤的早期辅助诊断成为临床肿瘤学的一大热点,具有简便、无创伤等优点。与肺癌相关的肿瘤标志物有40多种,其中恶性肿瘤特异性生长因子(TSGF)在临床中较为常用。对8 Early detection of lung cancer, early diagnosis, early treatment, to improve the cure rate is essential. With the development of molecular biology, the detection of tumor markers for the early diagnosis of malignant tumors become a hot clinical oncology, with the advantages of simple, non-invasive and so on. There are more than 40 kinds of tumor markers associated with lung cancer, of which, malignant tumor-specific growth factor (TSGF) is more commonly used clinically. Right
