[Primary sacral tumors: analysis of results and complications]

Primary sacral tumors are rare, treatment in most cases is surgical with or without adjuvant radiotherapy; oncology and functional results are usually adverse with a high rate of complications.

We conducted a retrospective, analytical and observational studies that includes 22 cases treated between 2000 and 2017, analyzed their characteristics demographic, the type of treatment received, and the oncological, functional results and the rate of complications were analized.

22 patients were subjected to sacrectomy with posterior approah because of cordoma (13 patients), giant cell tumour (three patients) and other (six patients). Three total sacrectomies, 13 partial sacrectomies, two hemisacrectomies and four sacrectomies enlarged were performed. The mean surgical time was 229 minutes, with an average bleeding of 2,100 cm3, the average tumour size was 13.8 cm (6-30cm); 10 patients were presented with complications, eight by surgical site infection, one sacral hernia and one osteomyelitis. Overall survival was 44.4 months.

Treatment of sacral tumors is complex, requires a multidisciplinary team; the oncological result is adequate when you get free margins of neoplasia, the functional results will be determined by the type of resection, and the rate of complications is high however is the best alternative healing in our hospital.
