title: [Retrospective study of tumor growth and progression in gastric leiomyosarcoma; a care report].
abstract: 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.
