Surgical treatment of adenocarcinoma of the cardia.

BACKGROUND. Adenocarcinoma of the gastric cardia presents different features from other gastric carcinomas. This study was performed to analyze the results of a 40-year experience with these lesions. METHODS. Of the 365 patients reviewed, 211 (57.8%) underwent resection. One hundred fifty patients underwent total gastrectomy with lower esophageal resection (TGER) and 46 underwent proximal gastrectomy with distal esophageal resection (PGER). More recently, 15 patients were submitted to total gastrectomy with subtotal esophagectomy (TGSE) without thoracotomy. RESULTS. The tumors were far advanced in most patients: extraparietal invasion in 77.7% of patients, lymph node involvement in 55%, and distant metastases in 11%. The postoperative mortality rate was 25.1% in patients who underwent resection: 26.7% after TGER, 17.4% after PGER, and 33.3% after TGSE (difference not significant). Cardiovascular and respiratory complications were common causes of death after both TGER and PGER. After TGSE, deaths were related exclusively to local complications, mainly as a result of cervical anastomotic leaks. The actuarial 5-year survival rate for all patients surviving resection was 16.7%. No improvement in the results of surgical therapy was observed during the past 20 years. The actuarial 5-year survival rate was significantly affected by pathologic staging: 61.0% stage I, 23.3% stage II, 9.8% stage III, and 0% stage IV (p less than 0.001). No significant differences in actuarial 5-year survival rates were observed between TGER (17.8%) and PGER (14.9%). Sex, duration of symptoms, and histologic type did not reveal prognostic significance. CONCLUSIONS. In early tumors a total gastrectomy with resection of 10 cm of esophagus above the tumor is advocated.
