转移和侵袭是恶性肿瘤的重要特征,也是恶性肿瘤患者死亡的重要原因。近年来,随着影像学、病理学、免疫组化技术及分子生物学技术的发展,微转移的诊断水平有了长足的进步,已能在肿瘤患者的外周血、骨髓、淋巴结中检测出常规临床检查无法发现的转移灶—微转移灶。淋巴结检测微转 Metastasis and invasion is an important feature of malignant tumors, but also an important cause of death in patients with malignant tumors. In recent years, with the development of imaging, pathology, immunohistochemistry and molecular biology techniques, the level of diagnosis of micrometastases has been greatly improved, and routine tests have been performed on peripheral blood, bone marrow and lymph nodes of cancer patients Clinical examination can not be found in metastases - micrometastasis.
