Objective: There are limited studies in the literature reporting clinical outcomes of malignant sacrum tumors due to their rarity. The aim of this study was to evaluate mid-term clinical outcomes of malignant sacrum lesions surgically treated by a single surgeon. Materials and Methods: Patients who were surgically treated with the diagnosis of sacrum tumor were retrospectively analyzed. Patients who underwent surgical resection of malignant sacrum tumors were included. Exclusion criteria were incomplete medical records and follow-ups. Patients’ demographics, type of the tumor, histopathological diagnosis, presence of neurologic deficit, type of approach, type of resection, presence of lumbopelvic fixation, postoperative complications, and recurrence rates were noted from our medical records. Results: A total of 15 patients (7 females, 8 males) with a mean age of 43.3 years participated in the study. The most common histopathological diagnosis of the malignant sacrum tumor was chordoma that was seen in 10 of 15 patients (67%). Soft-tissue tumors (leiomyosarcoma and malignant mesenchymal tumor) were seen in 2 patients (13%), metastatic tumors (renal cell carcinoma and malignant melanoma) in 2 patients (13%), and primary osteogenic tumor (chondrosarcoma) in 1 patient (7%). Perioperative and postoperative complications were encountered in 7 of 15 patients (47%). Conclusion: Chordoma was the most encountered malignant tumor of the sacrum according to our findings. Recurrence of the malignant sacrum tumor was so common that half of our patients had a history of previous treatment. It was remarkable that perioperative and postoperative complications were also common.
