Operational techniques and combination treatment for the recurrent sacro-coccygeal tumor.

This article presents 6 cases of recurrent sacro-coccygeal tumor with analysis of the causes of recurrence, operational technique for second-time operation and concomitant treatment. It is suggested that combined abdominal and sacro-coccygeal approaches be used to excise maximal mass of the tumor, surrounding affected tissues be curetted out and the space be filled up with adriamycin-bone-cement to destroy remaining tumor cells and to strengthen the stability of pelvis. Besides, the patients should be subject to supersegregation radiotherapy in order to minimize the possibility of recurrence.
