Abstract:
Objective To analyze the prognostic factors of patients with adenocarcinoma of gastroesophageal junction (AGEJ) after radical resection. Methods In this retrospective study, 269 patients with AGEJ who underwent curative resection from March 2004 to June 2007 were enrolled.The survival curve was drawn by Kaplan-Meier method and the survival analysis was done by Log-rank test. Univariate and multivariate analyses of the prognostic factors of AGEJ were made by Cox model. Results The overall 5-year survival rate of 269 patients was 25.0 % with the median survival time of 22 months.The Siewert type and the number of positive lymph nodes could influence the survival rate (both P < 0.05). Among the 269 patients, 216 (80.3 %) were Siewert Ⅱ type, their median survival time was 30 and 12 months in the thoracic surgery group and the laparotomy group when the tumor diameter was 3-7 cm, the difference was statistically significant (χ2= 5.036, P= 0.025). Univariate analysis showed that tumor diameter, pT, pN, operation time, age and sex were significantly associated with survival rate (all P < 0.05). Cox multivariate analysis showed that patients with a more advanced tumor size suffered from a poorer prognosis (P< 0.05). The risk of postoperative death in patients with lymph node metastasis was 1.854 times that of patients without lymph node metastasis. Conclusions Patients with AGEJ are predominantly Siewert Ⅱ type, the transthoracic approach or thoracoabdominal approach are reasonable selections for these patients. Tumor diameter and pN are independent prognostic factors of AGEJ patients.
