| Abstract | <p>We compared gadolinium diethylenetriaminepentaacetic acid (Gd-DTPA) enhanced T1-weighted images (T1-Gd) with the histopathological findings in 13 patients with bone or soft tissue sarcomas. Signal intensity of the viable tumor tissue was increased in T1-Gd in 92% of the patients. The necrotic or cystic areas in the tumor were not enhanced, rendering them distinctly. The degree of enhancement of the edematous area around the tumor was similar to or more marked than that of the tumor in 54% of the patients. Area showing inflammatory cells infiltration and edematous areas in the tumor tissue were also enhanced. Thus, the effect of preoperative chemotherapy in tumor tissues other than necrotic and cystic areas tended to be underestimated in T1-Gd. Its effect should be comprehensively evaluated based on not only T1-Gd but also T2-weighted images and findings of other imaging techniques.</p> |

| Abstract | <p>We evaluated the surgical problems encountered during treatment of 14 patients with malignant tumors originating in the pelvic region at our department. The tumor involved the iliac bone in 6 patients, the ischial bone in 2, the pubic bone in 2, and the gluteal region in 4. Invasion to the sacrum was observed in 7 patients. Twelve patients underwent surgical procedures consisting of intralesional resection in 6, marginal resection in 3, and wide margin resection in 3. Six of the 7 patients with sacral invasion developed local recurrence. Two patients with chondrosarcoma and one with parosteal osteosarcoma survived for 4 or more years, but the mean survival period in those with high grade malignant tumors was 11 months. These findings indicate the difficulties encountered in the treatment of malignant pelvic tumors.</p> |

| Abstract | <p>Radiological findings on the fate of grafted Kiel bone implants for the treatment of bone tumors were evaluated in 25 lesions. The mean follow-up period was 14.8 years, ranging from 5 to 21.8 years. We classified the radiological findings into 4 grades; Excellent (4 lesions), Good (14 lesions), Fair (2 lesions), and Poor (5 lesions). All cases of the Poor grade were polyostotic fibrous dysplasia. The younger the patient at the time of the operation, the more rapidly Kiel bone grafts tended to be incorporated. The grafted bone can become enmeshed in the structure of the recipient bed (Good or Excellent grades) within 10 years in most cases, except in polyostotic fibrous dysplasia.</p> |
