Abstract
Surgery, as the mainstay of treatment for localized esophageal cancer, is currently being challenged by the assumed high risk of esophagectomy and the poor longterm survival after resection. Epidemiologic and clinical changes over the past decade indicate that these assumptions should be reevaluated. The aim of this study was to assess the modern outcomes of esophagectomy for adenocarcinoma. We studied 263 consecutive patients (215 men, 48 women), who had esophagectomy for adenocarcinoma from 1992 to 2002. Ninety-seven (37%) were stage I, 63 (24%) were stage II, 93 (35%) were stage III, and 10 (4%) were stage IV. Forty-five percent (119 of 263) had curative en bloc resection, 52% (138 of 263) had node involvement, and 18% (48) received neoadjuvant therapy. Seventeen percent (44 of 263) of the patients were identified in a Barrett’s surveillance program. The frequency of T1N0 adenocarcinoma increased over the study period (p = 0.024). The overall 5-year survival was 46.5%, and for the last 5 years of the study was 50.4%. The overall 5-year survival for stage I was 81%; for stage II, 51%; for stage III, 14%; and for stage IV, 0%. Complications occurred in 61% and there were 12 perioperative deaths (4.5%). Cox proportional hazard analysis identified tumor stage and type of resection as independent predictors of survival. Nearly half of patients undergoing esophagectomy for adenocarcinoma survive ≥ 5 years. Improvements in survival are associated with increased detection of early stage disease, and a liberal use of en bloc resection. Nonsurgical treatments should be compared with these contemporary outcomes measures.
