Clinicopathological Characteristics and Prognostic Factors of Patients with Siewert Type II Esophagogastric Junction Carcinoma: A Retrospective Multicenter Study

The incidence of esophagogastric junction (EGJ) carcinoma is increasing, but its optimal surgical management remains controversial.
We retrospectively reviewed the database of 400 patients with Siewert type II EGJ carcinoma who were treated surgically at 7 institutions between March 1986 and October 2010. We examined the clinicopathological characteristics, prognostic factors, and risk factors associated with each recurrence pattern.
The 5-year overall survival rate of all patients with Siewert type II EGJ carcinoma was 58.4 %. Multivariate analysis showed that T and N stages were independent prognostic factors. We also found that the incidence of lower mediastinal lymph node metastasis (17.7 %) and para-aortic lymph node metastasis (16.1 %) was relatively high. In addition, the para-aortic lymph nodes (N = 39, 9.8 %) were the most frequent node recurrence site, followed by the mediastinal lymph nodes (N = 23, 5.8 %). Lung recurrence was more common than was peritoneal recurrence. Considering each type of recurrence, multivariate analysis showed that the differentiated type was associated with a higher risk of lung recurrence than was the undifferentiated type, and N stage (pN2–3) and positive venous invasion were independent risk factors for liver recurrence.
This study is one of the largest retrospective studies to evaluate patients with Siewert type II EGJ carcinoma. Para-aortic and mediastinal lymph node metastasis and recurrence rates were relatively high. During the postoperative follow-up of patients with differentiated Siewert type II EGJ carcinoma, patients should be monitored for lung recurrence more closely than that for peritoneal recurrence.
