Sumario: | BACKGROUND: For the treatment of locally advanced (T4) gastric cancer, extended multi-organ resection remains controversial. This study aimed to evaluate the surgical outcomes and survival of patients with T4 gastric cancer extending to the transverse colon. METHODS: A total of 2,652 gastric cancer patients underwent surgery between December 2011 and December 2015. Data from 40 of these patients who underwent curative resection for T4 gastric cancer extending to the transverse colon were obtained. Patient characteristics, related complications, long-term survival, and prognostic factors for T4 gastric cancer were analyzed. RESULTS: Postoperative morbidity occurred in 5 (12.5%) patients. All of the patients were cured with conservative treatment. No procedure-related mortality occurred. The 1-, 3-, and 5-year overall survival (OS) rates were 75.0%, 49.2%, and 36.9%, respectively, with a median survival time of 24 months. Univariate analysis revealed tumor size (P=0.049), advanced T stage (P=0.013), and lymph node metastasis (P=0.006) to be poor prognostic factors of OS. Advanced T stage and lymph node metastasis were identified by multivariate analysis as being independent prognostic factors. Further, it was observed that lymph node metastasis grade was associated with poorer OS. CONCLUSIONS: Patients with T4 gastric cancer extending to the transverse colon might benefit from curative resection with acceptable morbidity and mortality. |
