Current advances in animal model of chondrosarcoma and related research.

Chondrosarcoma is a type of malignant cartilage tumor with a high local recurrence. Due to its resistance to chemo- and radiotherapy, current treatment is limited to surgical resection. Animal model is one of the most important approaches to studying this disease, although systematic reporting on its development is rare. In this review, we summarized the elements involving animal model establishment. On the basis of these elements, we further classified chondrosarcoma animal models into various types. In addition, we compared various measurements for evaluating the animal model. Finally, its specific applications were discussed.
