The clinic-pathologic analysis of 66 cases with soft tissue sarcoma of abdomen

Abstract

We accepted 66 cases with soft tissue sarcoma of abdomen testified by the pathologists. The ratio of male to female was 1.5 to 1, but the aged-groups in female were more. The male incidences increased as the ages did. The mean age was 46.79 ± 17.04. The neoplasms arises more often in the abdominal wall below 30 years old, and it does mainly in the abdominal viscera and in the retroperitoneum over 30 years old. Fibrosarcoma protuberance was the main type in the abdominal wall, and leiomyosarcoma was the main type in the abdominal viscera, and in the retroperitoneum, the most was liposarcoma, the following was leiomyosarcoma. Among the soft tissue sarcoma of the abdomen, the most was in retroperitoneum, and the following was in abdominal viscera. Therefore, it was difficult to diagnose early. The keys to the question were B-mode ultrasonic examining, computed tomography (CT) scanning and magnetic resonance imaging (MRI). Surgery was the primary therapeutic modality. The resectability was the major prognostic factor. Radiotherapy and chemotherapy indicated a clear beneficial effect on soft tissue sarcoma of the abdomen and they can slightly decrease the recurrences and the metastases, but they had no obvious influence on the survival. In 5-year survival, the lesion of abdomen was the best, and those both of abdominal viscera and of retroperitoneum were the bad. To increase the 5-year survival, what counts are early diagnosis and the resectability.
