摘要
微转移是恶性肿瘤在发展过程中所形成的尚处于临床不可探测阶段的微小转移灶,播散并存活于淋巴系统、血液循环、骨髓、肝、肺等组织器官中,是恶性肿瘤复发和转移的根源。微转移与胃癌的发展及预后密切相关,胃癌微转移检测可用于指导胃癌的分期诊断和制订个体化治疗方案。现就胃癌微转移检测研究的现状和存在的问题予以综述。
Micrometastases are clinically undetectable occult metastases disseminated to and survived in the lymphatic system,circulation system,bone marrow,liver,lung,and other organs and tissues in the progression of malignancies from which overt metastases and recurrences may eventually generate.Recent studies demonstrate that micrometastases is closely related to the prognosis of gastric carcinoma and the staging and treatment of gastric carcinoma can be greatly improved by detecting micrometastases of gastric carcinoma.Here is to give a brief review on the advances and existing problems in detecting micrometastases of gastric carcinoma.
