Surgical outcomes and survival for T4 gastric cancer extending to the transverse colon

Purpose Extended multi-organ resection for locally advanced (T4) gastric cancer remains controversial. Herein we aimed to evaluate the surgical outcomes and survival of patients with T4 gastric cancer extending to the transverse colon. Materials and Methods Between 2011 and 2015, forty patients had undergone curative resection for T4 gastric cancer extending to the transverse colon. Patient characteristics, related complications, long-term survival, and prognostic factors for T4 gastric cancer were analyzed. Results ost-operative morbidity occurred in 5 (12.5%) patients. The 1-, 3-, and 5-year overall survival rates were 75.0%, 49.2%, and 36.9%, respectively. Univariate analysis revealed that tumor size ( P =0.049), advanced T stage ( P =0.013), and lymph node metastasis ( P =0.006) are poor prognostic factors of overall survival. Based on multivariate analysis, advanced T stage and lymph node metastasis were identified as independent prognosis factors. Conclusions Patients with T4 gastric cancer extending to the transverse colon might benefit from curative resection with acceptable morbidity and mortality.
