肿瘤的微转移一般是指恶性肿瘤在发展过程中 ,播散并存活于血循环、淋巴道、骨髓及各组织器官中的肿瘤细胞尚未形成转移结节 ,无任何临床表现 ,常规检查方法如影像、常规病理检查等难以发现。肿瘤的转移与预后密切相关 ,所以检测微转移很重要。PCR技术的出现很大程度上促进了肿瘤微转移的检测。基因诊断检测出肿瘤微转移可作为加强术后辅助化疗的选择性标记 ,有助于建立个体化的治疗方案。
Micrometastasis of tumors generally refers to malignant tumors in the development process, disseminated and survive in the blood circulation, lymphatic vessels, bone marrow and various tissues and organs of tumor cells have not yet formed metastatic nodules, without any clinical manifestations, routine examination methods such as images, Conventional pathological examinations are difficult to find. Tumor metastasis is closely related to prognosis, so it is important to detect micrometastases. The appearance of PCR technology has greatly promoted the detection of tumor micrometastasis. Genetic diagnosis Detecting tumor micrometastasis can be used as a selective marker to enhance postoperative adjuvant chemotherapy and help establish individualized treatment options.
