Multiple chondrosarcoma is a kind of benign cartilage tumor, with low recurrence rate after resection and good prognosis, the impact on life expectancy should depend on the development of the tumor.
1. Multiple chondrosarcoma has the possibility of malignant transformation, the malignant transformation rate of solitary chondrosarcoma is less than 1%, while the malignant transformation rate of multiple chondrosarcoma is much higher, and the malignant transformation of chondrosarcoma requires extensive resection to prevent further development and spreading of the tumor and reduce the survival rate in 5 years, and the prognosis is mainly related to the severity of deformity caused by the tumor.
2. Multiple osteochondrosarcoma can cause pain, joint activity disorder, joint deformity, pathological fracture, etc. It should be resected by surgical method to remove the tumor lesion completely to avoid recurrence. For multiple chondrosarcomas that do not obviously affect bone strength or cause pain and other clinical symptoms, surgical treatment can be withheld for the time being, which will have less impact on the survival rate, and regular follow-up is sufficient.
Multiple chondrosarcoma requires regular observation and removal of the chondrosarcoma as soon as it has a tendency of malignant transformation.
