Abstract

Pelvic sarcoma is uncommon in children and challenging to treat. This study examined different surgical approaches to treat pelvic sarcoma with the aim of assessing the oncologic, and functional outcomes.
We retrospectively examined the medical records of patients younger than 21 years of age who underwent surgery for pelvic sarcoma at our institution from 1992 to 2010. The functional status of the patients was examined after a minimum follow-up of two years.
Twenty-six patients were included in the analysis. Nineteen (73%) patients were male and seven (27%) were female. Mean age at presentation was 12.0 ± 3.9 years. Nineteen patients had Ewing sarcoma (73%), five had osteosarcoma (19%), one had chondrosarcoma (4%) and one had rhabdomyosarcoma (4%). Iliac wing resection with no reconstruction was done in three patients. Reconstruction with free fibular graft A-frame was performed in four patients, saddle endoproshtesis in five patients, iliac autoclave in one patient, and internal hemipelvectomy in nine patients. Hindquarter amputation was performed in five patients. Median follow-up was 4.6 years (range, 2.6–16 years). Nineteen patients were alive (73%); of those, 13 were known to be without disease, three were with disease and three did not have known tumor status. Six patients were reported deceased, three had osteosarcoma and three had Ewing sarcoma. Function was assessed in 17 patients; 64% were asymptomatic and ambulatory and 36% were symptomatic and ambulatory.
Salvage reconstruction for pelvic sarcoma can be performed through various procedures on the extent of necessary bony resection. Survival rate and functional outcomes were promising in the performed study.
