Abstract 4317
Background
Adenocarcinoma of esophagogastric junction (AEG) is a special type of malignant tumor which occurs in the upper gastrointestinal tract. However, AEG is different from esophageal or gastric cancer. Its biological behavior is complicated and prognosis is poor. Even after radical resection, the overall 5-year survival rate is still very low. An in-depth analysis of the prognostic factors in patients with AEG may indicate a certain direction for clinical treatment and decision-making as well as for improving the prognosis of patients with AEG. Although some researchers have explored the factors influencing the prognosis of AEG, the independent prognostic factors are still unclear, which need to be further studied.
Methods
The clinical data of patients with AEG who underwent surgical treatment in PLA general hospital from January 2009 to January 2013 were collected retrospectively. According to the inclusion and exclusion criteria, a total of 343 patients with AEG were included in the study. Sex, age, basic disease, Siewert classification, tumor size (Diameter), differentiation, vascular cancer thrombus, nerve invasion, T-stage,N stage, pTNM, approach, minimally invasive surgery, resection scope, adjuvant chemotherapy, HER-2 and Ki-67 expression were analyzed comprehensively to study the independent or nonindependent prognostic factors in patients with AEG.
Results
The median follow-up time of the 343 patients with AEG was 50.2 months. The 5-year overall survival rate of the whole group (no IV stage) was 49.2%. Univariate analysis showed that age, basic disease, Siewert classification, tumor size (Diameter), differentiation, vascular cancer thrombus, nerve invasion, T-stage,N stage, pTNM, adjuvant chemotherapy, level of Ki-67 expression was correlated with prognosis (P < 0 05). Multivariate analysis showed that age, tumor size(Diameter), differentiation, pTNM and adjuvant chemotherapy were independent prognostic factors affecting the overall survival of the patients (P < 0 05).
Conclusions
The age, tumor size (Diameter), differentiation degree, pTNM and adjuvant chemotherapy were independent prognostic factors affecting the overall survival rate of patients with AEG (P < 0 05).
