Abstract
- Simple Summary: Sacrectomy represents a radical indication for bone sarcomas (e.g., osteosarcoma or chondrosarcoma) and chordomas, as well as selected carcinomas with invasion of the sacrum. Extralesional en bloc excision is surgically demanding and associated with resection-induced neurologic deficits and risks. Due to the low incidence of bone sarcomas, the rare localization in the sacrum and the complexity of the surgical procedure, studies reporting on the oncological outcome and corresponding complications in larger patient numbers are rare. The aim was to describe the oncosurgical management and the complication profile and to analyze our own treatment results after partial/total sacrectomy, with attention paid to a possible benefit by using intraoperative 3D navigation. There was a significant difference in progression-free and metastasis-free survival between sarcoma, chordoma and carcinoma patients. Complications were common, but no independently influencing causative factors could be identified. Although there was a subjective impression of improved intraoperative 3D orientation and easier identification of resection planes, the use of navigation did not significantly influence resection status or oncological patient outcome. Introduction: Bone sarcoma or direct pelvic carcinoma invasion of the sacrum represent indications for partial or total sacrectomy. The aim was to describe the oncosurgical management and complication profile and to analyze our own outcome results following sacrectomy. Methods: In a retrospective analysis, 27 patients (n = 8/10/9 sarcoma/chordoma/locally recurrent rectal cancer (LRRC)) were included. There was total sacrectomy in 9 (incl. combined L5 en bloc spondylectomy in 2), partial in 10 and hemisacrectomy in 8 patients. In 12 patients, resection was navigation-assisted. For reconstruction, an omentoplasty, VRAM-flap or spinopelvic fixation was performed in 20, 10 and 13 patients, respectively. Results: With a median follow-up (FU) of 15 months, the FU rate was 93%. R0-resection was seen in 81.5% (no significant difference using navigation), and 81.5% of patients suffered from one or more minor-to-moderate complications (especially wound-healing disorders/infection). The median overall survival was 70 months. Local recurrence occurred in 20%, while 44% developed metastases and five patients died of disease. Conclusions: Resection of sacral tumors is challenging and associated with a high complication profile. Interdisciplinary cooperation with visceral/vascular and plastic surgery is essential. In chordoma patients, systemic tumor control is favorable compared to LRRC and sarcomas. Navigation offers gain in intraoperative orientation, even if there currently seems to be no oncological benefit. Complete surgical resection offers long-term survival to patients undergoing sacrectomy for a variety of complex diseases. [ABSTRACT FROM AUTHOR]
