淋巴结显像技术是肿瘤学和外科学研究的新热点。目前,该技术已成功用于黑色素瘤、乳腺癌等手术。由于胃淋巴引流复杂、存在跳跃转移以及假阴性率较高,该技术尚未应用于胃癌临床实践,其可行性和适用性尚无定论。因此,淋巴结显像技术应用于胃癌,还有许多问题需要回答。 Lymphatic imaging is a new hot spot in oncology and surgery. At present, the technology has been successfully used for melanoma, breast cancer and other surgery. Due to the complexity of gastric lymphatic drainage, the presence of jumping metastasis and a high false negative rate, this technique has not been applied to clinical practice of gastric cancer, its feasibility and applicability are not conclusive. Therefore, lymph node imaging techniques applied to gastric cancer, there are many questions need to answer.
