Esophagogastric junction adenocarcinoma: multivariate analyses of surgical morbi-mortality and adjuvant therapy.

BACKGROUND In recent years the literature has recorded a progressive increase in the prevalence of adenocarcinoma of the esophagogastric junction. Several factors can interfere with the morbidity and mortality of surgical treatment. AIM Non-randomized retrospective study of prognostic factors of operated patients by adenocarcinoma of esophagogastric junction, with or without post-operative chemotherapy and radiotherapy. METHODS Medical records were reviewed from patients treated at university hospital in the period of 1989 and 2009, to obtain data about pre and postoperative treatment. Cox's univariate and multivariate regression analysis of risk factors for prognostic of these patients were done with level of significance of 5 %. RESULTS Were reviewed 103 patients distributed as: 1) 78 (75.7%) patients without adjuvant therapy, and 2) 25 (24.3%) with it. All patients underwent surgical resection with curative intent. Cox's multivariate regression analysis of all patients showed that: lymphnode invasion N2 had greater risk of death in 5.9 times; broncopneumonia, in 11.4 times; tumoral recurrence during clinical following greater in 3.8 times. CONCLUSION Tumoral recurrence, lymphnode metastasis and broncopneumonia in the postoperative period were factors of bad prognosis and contributed significantly to increase morbimortality and decrease global survival.
