Objective · To summarize the clinical characteristics and prognostic factors of pelvic chondrosarcoma. Methods · A total of 73 cases of chondrosarcoma were collected, including 24 of pelvic. The clinical characteristics and prognostic factors of pelvic chondrosarcoma were analyzed by statistic methods. Results · The ratio of men to women was 1.4:1,and the median age is 43.5 years old. According to the classification of pelvic proposed by Enneking, there were 5 in region Ⅰ , 14 in region Ⅱ , and 5 in region Ⅲ . On histological review, 1 was grade 1, 15 were grade 2 ,and 8 were grade 3. The histologic types included 17 conventional, 3 dedifferentiated, 2 secondary, and 1 mesenchymal. The overall survival rates of pelvic chondrosarcoma were （82.2±8.1） %,（77.3±8.9） % and（52.4±12.1） % for 3, 5 and 10 years respectively. Local recurrence rate of pelvic chondrosarcoma (83.3%) was significantly higher than those of other sites (34.7%)(P=0.000), and the proportion of amputation was significantly higher than the other sites (50.0% vs 20.4%, P=0.000), but there was no significant difference in the overall survival between the two groups (P=0.216). Conclusion · Pelvic chondrosarcoma have a higher local recurrence rate than the other sites and is tend to result in amputation. Early local recurrence after surgery indicates poor prognosis.
