支气管肺泡灌洗诊断肺部肿瘤的研究进展

Research progress of bronchoalveolar lavage in diagnosing lung tumor

肺癌是我国发病率最高的肿瘤之一，因而对其进行早期诊断、早期治疗尤为重要。在诊断方面，除了借助影像学方法外，还可以采用纤维支气管镜常规活检及刷检，但是在对早期肺癌和周围型肺肿瘤的诊断上仍有较大困难。随着支气管肺泡灌洗（bronchoalveolar lavage，BAL）技术的广泛开展和对支气管肺泡灌洗液（bronchoalveolar lavage fluid，BALF）细胞学及肿瘤标记物的研究，BAL的诊断价值逐渐被人们所重视。国内外学者在BALF细胞学和分子生物学等方面进行了大量研究，取得了显著的成果。

Lung cancer is one of the highest incidence of tumor in China,therefore,the early diagnosis and the early treatment are very important. In the part of diagnosis, beside the imageology methods, the biopsy and brushing examination with bronchofibroscope are used now. But there is much difficulty in diagnosis of early lung cancer and peripheral lung tumor. Along with the extensive development of bronchoalveolar lavage technique and the research of cytology and tumor markers of bronchoalveolar lavage fluid,the value of diagnosis of bronchoalveolar lavage is gradually to be thought highly of. Many scholars have done large of researches in cytology, molecule and gene territory, and have got predominant achievements.
