The reason is the tumor cells escape the immunosurveillance whose mechanism is very complex. In general, the explanation is based on two aspects, one is that the tumor cells can passively escape the host immunosurveillance when the host immnue state is low and another is tumor cells can actively secrete factors to down-regulate immune function.

肿瘤逃避免疫监视的机制非常复杂，但总体上可从宿主免疫状态及肿瘤细胞等方面来解释，在宿主免疫状态低下时，肿瘤细胞可以被动地逃避免疫监视，但是肿瘤细胞也能主动地释放一些活性物质，下调免疫杀瘤作用，该作用主要通过两个途径，即对免疫细胞功能的调节和免疫细胞数量的调节。
