Excision is the treatment of choice in cases of sacral chordoma. Local recurrences, however, have often been observed even after total en bloc resection. The authors assessed outcomes in four cases of tumor recurrence in patients who underwent total en bloc S2-3 resection for sacral chordomas that were located below S-3. The primary recurrences were located at either side of the lateral portion of the remaining sacrum in all patients. In two patients in whom preoperative magnetic resonance imaging indicated no invasion of the tumor into surrounding soft tissues, recurrence in the resected end of the gluteus maximus or piriformis muscle was also observed. The authors therefore recommend that the S2-3 sacrectomy should be performed over an adequate margin, including a part of sacroiliac joints at the bilateral portions of the sacrum and soft tissues such as the gluteus maximus or piriformis muscle.
