Surgical management of gastric leiomyosarcoma: evaluation of the propriety of laparoscopic wedge resection.
Laparoscopic surgery has been applied to malignant gastric tumors. To evaluate the propriety of laparoscopic wedge resection for gastric leiomyosarcoma it is necessary to question whether lymph node dissection is necessary for the surgical management of gastric leiomyosarcoma. A retrospective study on open surgery cases of gastric leiomyosarcoma was performed to address this issue. The clinical records of 28 patients with gastric leiomyosarcoma who had had surgery were examined. The patients who underwent open surgery were divided into a systematic lymph node dissection (SLND) group (n = 9) and a nondissection (non-D) group (n = 19). No patient had lymph node metastasis at the time of operation or recurrence, and statistical analysis showed no difference between the SLND and non-D groups in terms of survival rates. These data suggest that SLND might not be necessary for the surgical management of gastric leiomyosarcoma and that laparoscopic wedge resection of the stomach can be considered a first-line treatment for gastric leiomyosarcoma.
