COL18A1 and neoplasm: The tumour growth rate in the 32P-colloid combined with endostatin group was the lowest among all groups, even significantly lower than that in either 32P-colloid or endostatin alone group, suggesting that endostatin could enhance the effect of 32P-colloid on killing tumour cells, which was further supported by the massive tumour cell necrosis, sparsely arranged nascent tumour cells and significantly declined MVD in the 32P-colloid combined with endostatin group as compared with other groups.
