Radical neurosurgical excision of sacral tumors, causing compression of neural structures, the results of treatment

Abstract

Introduction. Radical surgical removal of sacral tumors requires extensive operations performing, which cause pelvic ring stability lesion and probable neural structures damage. Materials and methods. The data, obtained at analysis of different examination methods, radical surgical “block” excision of sacral tumors, clinical results of treatment of 12 patients with sacral tumors, operated in 2009–2012, are given. In 10 of them large tumors with all sacrum lesion (S I –S V vertebrae) were revealed, in 2 — with upper sacral vertebrae lesion (S I –S III ), in 1 — lower sacral vertebrae lesion (S III –S V ). In all patients after tumor excision pelviolumbar fixation was done. Results . In the late period results of 12 patients (group A) treatment, at wich tumor “block” removal was performed, were compared with results of 23 patients treatment (group B) with sacral tumors, removed by division into parts. In 10 of them large sacral tumors were found with all sacrum lesion (S I –S v ), in 8 — upper sacral vertebrae lesion (S I –S III ), in 5 — lower sacral vertebrae lesion (S III –S V ). In 6 patients after tumor excision pelviolumbar fixation was done. Conclusion . Results of treatment and prognosis at sacral malignant tumors were better after radical surgery, reliable intraoperative spine to the pelvic ring fixing, use of radiotherapy and chemotherapy after operation.
