Multivisceral resection for locally advanced gastric cancer: A retrospective study.

BACKGROUND Multivisceral resection may be the exclusive radical procedure for cT4b gastric cancer patients. However, most surgeons refuse to select surgery because of the theoretical higher mortality, morbidity and poorer prognosis. METHODS We retrospectively reviewed cT4b gastric cancer patients who underwent surgery from January 1,1997 to December 31,2018. The primary endpoint was overall survival. Short-term results and prognostic values of clinical and pathologic factors were also analyzed. RESULTS Patients underwent multivisceral resection had an acceptable mortality and morbidity. The overall 5-year survival rate of multivisceral resection was higher than that of palliative surgery (P  15), vascular cancer emboli, and postoperative chemotherapy. CONCLUSIONS cT4b gastric cancer patients underwent multivisceral resection experience acceptable mortality and morbidity. The independent prognostic factors for multivisceral resection were completeness of resection, extensive lymph node involvement (>15), vascular cancer emboli, and postoperative chemotherapy.
