为了研究肿瘤转移的机理和预防以及阻断转移的方法,首先需要建立肿瘤转移的实验动物模型。理想的肿瘤转移模型最重要的条件是转移发生率高而且稳定。目前我国还没有一株可移植的淋巴道转移模型,国外虽然有一些,但转移率不高。至于可移植性肿瘤自发淋巴道合并血道同时有双向转移的瘤株,尚未见报道。本文报告一株我室自己建立的小鼠可移植性瘤株子宫颈癌27号自发转移的研究。 In order to study the mechanism of tumor metastasis and the methods of preventing and blocking metastasis, it is first necessary to establish an experimental animal model of tumor metastasis. The most important condition for an ideal tumor metastasis model is the high and stable rate of metastasis. At present, there is no transplantable lymphatic metastasis model in China. Although there are some foreign countries, the transfer rate is not high. As for the transplantable tumor spontaneous lymphatic tract with bidirectional metastasis, it has not been reported. This article reports on the spontaneous metastasis of cervical cancer No. 27 in a mouse transplantable tumor strain established by our laboratory.
