[Clinical study of 76 cases of smooth muscle tumor of the stomach].
Seventy six patients with smooth muscle tumor of the stomach (18 leiomyoma, 58 leiomyosarcoma) operated at Cancer Institute Hospital are presented. 1) Advanced age, short duration of illness, region of the middle portion of the stomach, large tumor size and ulcerative tumor were suggestive of pathological malignancy. 2) Male, symptomatic and larger tumor size were suggestive of poor prognosis. 3) The rate of curative surgery was 94.8% for fifty eight patients with leiomyosarcoma. The cumulative five-year survival rate after curative operation was 74.9% for all patients with leiomyosarcoma. Regardless of resecting method, all patients with tumors less than 5 cm in diameter lived without any indication of recurrence. 4) Four of the 58 patients with leiomyosarcoma had regional lymph node metastasis and died at less than 5 years following operation.
