结直肠癌肺转移的临床治疗现状

Current Status of Treatment for Lung Metastases in Patients with Colorectal Cancer

肺转移是继肝转移后结直肠癌最易发生转移的部位,其发生率约10%～20%,是影响结直肠癌患者预后的重要因素。与肝转移相比,肺转移的相关研究相对较少,存在的争议较多,其发生转移机制尚不明确,有效治疗手段以及影响预后的因素有待继续研究。本文旨在从转移机制、临床特点、治疗策略等方面总结结直肠癌肺转移的临床研究现状及进展,以期为结直肠癌肺转移的临床及科研提供参考。

The lung is the most common site of metastasis following the liver in patients with colorectal cancer(CRC).The incidence of lung metastasis is about 10%~20%,which is an important factor affecting the prognosis of CRC patients.Compared with liver metastasis,less studies on lung metastasis have been carried out and the results are more controversial;the mechanisms of lung metastasis are not fully clear,and the effective treatment and prognostic factors need to be further explored.This article is to summarize the current status and progress of clinical researches on lung metastasis of colorectal cancer,focusing on the metastasis mechanism,clinical features and treatment strategy,providing reference for clinical and scientific research on lung metastasis of colorectal cancer.
