[Poor prognosis of XXXX of pelvis; 39 years of registration by the Netherlands Commission on Bone Tumors].

@entity1 @entity5 @entity530 @entity421 @entity3
OBJECTIVE: To evaluate the results of treatment in @entity1 with @entity421 of the pelvis. DESIGN: Retrospective. @entity1 AND METHODS: Sixty-five @entity1 with @entity530 registered in the files of the Netherlands Committee on Bone Tumours over 1957-1995 were reviewed. Complete information was obtained on 62 cases: 27 males and 35 females, median age was 31 years (range: 12-83). Distant @entity3 were present in 11 @entity1 (stage IIIB; 18%), while 50 @entity1 had @entity5 (81%) and 1 @entity1 stage @entity421 (2%). The results of treatment and survival were determined. RESULTS: Median survival was 14 months (2-177), the 5-year survival 15%. Distant @entity3 developed in 27 of 42 (64%) @entity1 with curatively treated @entity5 , with prolonged @entity3 -free survival after chemotherapy treatment (p < 0.0012). Survival in @entity1 with @entity530 was better after surgical resection of the primary @entity5 than after no operation (p < 0.0054); (neo)adjuvant chemotherapy gave no longer survival than surgery alone (p < 0.083). CONCLUSION: The prognosis of @entity530 was poor, despite modern multimodality treatment regimens, including surgical resection and chemotherapy.
