[Clinicopathological Study of Perforated Gastric Cancer Treated with Surgery].

This retrospective study evaluated an appropriate surgical treatment in patients with perforated gastric cancer. The clinicopathological and survival data on 17 perforated gastric cancer patients treated with surgery were analyzed. The one-stage or two-stage gastrectomy was performed in 8 and 5 patients, respectively. The omental patch repair was performed in 4 patients. In univariate analysis, non-curative(R2)resection with gross residual tumor(p<0.01)and postoperative complications( p=0.01)were found to be significant unfavorable factors for overall survival(OS). In multivariate analysis, R2 resection was identified to be an only independent significant unfavorable factor for OS. Patients who underwent curative(R0) resection had long-term survival, while patients with R2 resection and postoperative complication had limited survival times. These results suggest that R0 resection may be optimal to improve survival in patients with perforated gastric cancer, regardless of whether patients underwent a one-stage or two-stage gastrectomy based on the patient's condition.
