Presented is the case of a 58-year-old female who had been found to have a submucosal tumor of the stomach during a group medical examination 7 years earlier. Since that time, the proliferative course of the tumor has been regularly observed and the diagnosis of a gastric smooth muscle sarcoma was finally determined after an endoscopic examination performed this year. On the basis of X-ray photographs taken periodically, the mass gradually proliferated from 1.3 to 3.5 cm in diameter during the observation period of 2392 days. According to the doubling time (DT) calculation of Horai et al, the DT was 0.69. The proliferation in this case was very slow and this seems to be a characteristic of a highly differentiated smooth muscle sarcoma of the stomach.
本文介绍了一名58岁女性的病例，该患者在7年前的一次团体体检中被发现患有胃黏膜下肿瘤。从那时起，肿瘤的增殖过程一直被定期观察，今年进行内镜检查后最终确诊为胃平滑肌肉瘤。根据定期拍摄的X光照片，在2392天的观察期内，肿块直径从1.3厘米逐渐增大到3.5厘米。根据Horai等人的倍增时间（DT）计算，DT为0.69。该病例中的增殖非常缓慢，这似乎是胃高分化平滑肌肉瘤的一个特征。
