 Since planning the surgical margin in patients with soft-tissue sarcoma that has been inadequately resected previously is a very difficult problem, we assessed the usefulness of MRI in planning the surgical margin in such cases. Between 1991 and 1999, 18 patients with soft-tissue sarcoma that had been inadequately resected previously were treated in our hospital. Enhanced MRI, with or without fat saturation, was mainly used in performing the planning. The surgical margins were evaluated in the resected specimens, and their relation to treatment outcome was assessed. The postoperative surgical margins were evaluated as wide in 12 cases (67%) and marginal in 6 cases (33%). Local recurrence developed in 4 cases (22%) after the second operation. In 3 of them planning had been performed based on MRI studied without fat saturation;in 3 of them the margin was marginal;and in 3 of them was in the trunk. Recurrence after additional resection tended to the primary tumor develop in cases in which MRI had been performed without fat saturation, in which the surgical margin was marginal, and cases in which the primary tumor was in the trunk. In conclusion, enhanced MRI with fat saturation should be used to plan the surgical margin in patients with soft-tissue sarcoma, and the second operation should be performed with a wide margin.
