Sacral Tumor: Experience in a Single Institution

Research output: Contribution to journalArticlepeer-review


Introduction. Sacral tumors are rare, and experience of these tumors is usually limited to a small number of patients. Inthis study, we evaluated profile, survival rates, and functional outcome in a series of sacral tumor treated in our institution.Method. We retrospectively reviewed the records of 22 sacral tumor patients from January 1995 to February 2014 inCipto Mangunkusumo National Central Hospital, Jakarta, Indonesia. Kaplan-Meier method was used to describedsurvival and functional outcome. Their correlation with clinical profile, histological type, level of sacral involvement,treatment, and complication were analyzed by Log rank test.Results. From 22 patients, 5 of them were excluded from this study. Thus, there were 17 cases of sacral tumor, 16 ofthem were malignant and one case was benign. In Kaplan-Meier Analysis, there were no significant difference insurvival found between sex, age group, biopsy type, level of sacral involvement, treatment, and complication. There wassignificant difference in survival found between histopathology result (p=0.012), and giant cell tumor GCT showed thehighest survival, followed by chordoma, metastatic lession, and Ewing Sarcoma. Sacral tumor at the level of S2 andbelow had better functional outcome compared to the one above S2 (p=0.001). There were no difference in functionaloutcome found between histopathology type and treatment (p=0.137 and p=0.210).Conclusion. The majority of primary tumors of sacrum are chordoma which present with nonspecific early signs andsymptoms. Survival rate and functional outcome of the sacral tumor patients were determined by histopathology resultand level of sacral involvement. Lower level of sacral involvement lead to better survival and functional outcome.
