摘要
Overall prognosis of adenocarcinomas of the gastro-esophageal junction remains poor as most patients present with advanced disease. Aim-To examine the effects of preoperative chemoradiotherapy in locally advanced adenocarcinomas of the gastro-esophageal junction. Methods-Forty-two consecutive patients received a course of radiotherapy (45 Gy, administred in 25 fractions) with concurrent infusion of 5-fluorouracil and cisplatin, followed by surgery. Endoscopic ultrasonography was used to assess response to chemoradiotherapy. A transhiatal or a transthoracic approach was used for surgical resection. Tumor size, node invasion and margins of resection were analyzed. Results-Thirty-eight patients underwent subsequent surgery and complete resection (R0) was achieved in 34. Operative mortality was 13.2%(5/38). A his -tological complete response was observed in 6 patients. Median survival was 23 months (range: 15-31) and median disease-free survival was 19 months (range: 15-23). At one and two years, 70.7 and 45.6%of the patients were alive, respec tively. The pTNM status, node involvement and tumor size were predictors of survival. Conclusions -Pre-operative chemoradiotheropy is effective in patients with locally advanced carcinoma of the gastro-esophageal junction, resulting in high resection rates. However it seems to increase operative morbidity and mortality. Certain prognostic factors such as resection margins, need to be examined in further detail.
