- Аннотация: Introduction: Despite the advances of medical, surgical and radiation oncology local recurrences are very often in pelvic tumors due to difficulties of radical resection and achieving of negative margin. Aim: to analyze results of resection of pelvic bone tumors using image- guided computer navigation system. Material and methods: Since 2010 twenty nine resections were performed in patients with pelvic bone tumors with assistance of image- guided computer navigation system. There were 17 male and 12 female. Average age was 58 years (range26-74). In 19 cases tumors were located in pelvic bones, in 5 cases - in sacrum, in 5 cases - in sacroiliac joint. The most commonly found tumor was chondrosarcoma (19 cases). Three renal cancer mts , three chordoma, three Ewing sarcoma and one osteosarcoma were also found. Preoperative MRI and CT and 3D-views of the bone were performed each patient. Reconstructed images allowed preoperative surgical planning. The plane of tumor resection was defined and marked along the margin of the planned resection. Results: The mean time for intra-operative navigation procedure was 23 min (range12-47). The mean registration error was 1.1 mm (range 0,7-1,6mm). There were no intra-operative complication. Histological examination of all resected specimens showed a negative tumor margin. All patients were followed up from 6 to 48 mounts. There no recurrence in all cases, four patients died from distant metastasis. Conclusion: Resection of pelvic bone tumors using computer-guided navigation system allows to accurately determine lines of resection comparing with preoperative planning and to achieve negative margins.
