Zhonhua Wei Chang Wai Ke Za Zhi 9 2006 56-8. 7 The Role of Surgery in the Management of Esophageal Cancer and Palliation of Inoperable Disease Robert Mason Introduction In spite of improvements in diagnosis staging and treatment the outcome for patients with esophageal cancer remains poor. Although 1-year survival has improved in recent years there has been little change in the 5-and 10-year survival Figure . This is because many of the patients have metastatic disease with a large percentage having micrometastases. These have been found in the bone marrow in patients undergoing resection in 88 of cases 1 . A significant factor in the improved 1-year survival is the reduction in inhospital operative mortality Table 1 2 3 4 . This relates to improvement in staging fitness testing technique perioperative care and probably most importantly centralization of services in large centers Table 5 6 7 . In a study from the United Kingdom there was a 40 reduction in operative mortality for every 10 patient increase in a surgeon s caseload. 8 . Such large centers with dedicated teams can achieve inhospital mortality figures of less than 2 by utilizing a multidisciplinary team approach 4 . Another factor in improved short-term survival is the recognition that surgery alone is not the answer for most cases and that survival benefits can accrue by the use of preoperative neoadjuvant chemotherapy
