摘要
Abstract
Objective: To analyze the CT features of bronchovascular convergence sign in peripheral lung cancer, then to make a scientific approach to its mechanism and value in estimating prognosis of peripheral lung cancer. Materials and Methods: The CT features and pathological basis of bronchovascular convergence sign in 170 peripheral lung cancers proved by operation and pathology were analyzed retrospectively. According to number and grade the sign were divided into 0～Ⅲ degree The location of bronchovascular convergence sign in tumor were analyzed also. The relation between grade of bronchovascular convergence sign and size, stage, pathological changes of cancers were used to deduce mechanism of this sign, and to estimate prognosis of patients with lung cancer. Results: ① The vast majority of≤10mm small peripheral lung cancer had 0 dgree bronchovascular convergence sign,＞11mm peripheral lung cancer had more advanced bronchovascular convergence sign. No marked differences between 11～20mm and＞21mm peripheral lung cancer. ② Higher staged lung cancer had more advanced bronchovascular convergence sign ③ Bronchovascular convergence sign could occur any quarter of tumor, air-bronchogram more often in hilum quarter and peripheral quarter. Conclusion: ① Fibrosis and proliferation within peripheral lung cancer are fundamental cause formatting bronchovascular convergence sign ② Vascular convergence sign is not supply vessel and tumor vessel. ③ Bronchovascular convergence sign can be used to predict prognosis and malignance of peripheral lung cancer indirectly.关键词
