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 lei omyosarcoma 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 wa s performed to address this issue. The clinical records of 25 patients with gastric leiomyosarcoma who had had surgery mere examined. The pa tients who underwent open surgery were divided into a systematic lymph node dissection (SLND) group (n = 9) and a nondissection (non-D) grou p (n = 19). No patient had lymph node metastasis at the time of operat ion or recurrence, and statistical analysis showed no difference betwe en the SLND and non-D groups in terms of survival rates. These data su ggest that SLND might not be necessary for the surgical management of gastric leiomyosarcoma and that laparoscopic wedge resection of the st omach can be considered a first-line treatment for gastric leiomyosarc oma.
