Abstract
Objective
To establish a rabbit model of transplanted endometrial carcinoma with lymph node metastasis and observe its magnetic resonance imaging (MRI) features.
Methods
VX2 tumor grafts were orthotopically embedded in the endometrium of rabbits, and 3 weeks after the transplantation, the tumor and its metastasis to the retroperitoneal lymph nodes were examined by MRI, and the signal intensities and size of the lymph nodes were compared with those of normal rabbits.
Results
The orthotopic transplantation of the tumor grafts resulted in tumor growth in all the 12 recipient rabbits. The tumors infiltrated the serosa of the uterus and metastasized to the retroperitoneal lymph nodes 3 w after transplantation. MRI demonstrated that the lymph nodes of the tumor-bearing rabbits were larger in size than those of normal control rabbits, but the signal intensity of the lymph nodes was not significantly different between them.
Conclusion
This transplanted endometrial carcinoma model is characterized by high success rate and similar tumor metastasis behaviors with human endometrial carcinoma, therefore may serve as a good model for testing the efficacy of contrast agents for MR lymphography.
