BackgroundAdenocarcinomas of the oesophagogastric junction are increasingly being considered as a separated tumour entity. The prognosis is rather poorer compared with that for distal gastric cancer. Data from a multicentre study as part of research on clinical care aim to reflect the current situation in surgical treatment after inauguration of neoadjuvant modalities.Patients And MethodAs part of the ongoing prospective multicentre observational study QCGC 2 (German Gastric Cancer Study 2), 544 adenocarcinomas of the oesophagogastric junction (AEG 1-3) were registered from 01/01/2007 to 12/31/2009.ResultsPatients underwent surgical intervention in 108 (76.6 %) of the 141 surgical departments which provided data to the study. In 391 patients (82.5 %), R0 resection was achieved. Almost 60 % of the carcinomas of the oesophagogastric junction were approached in departments with no more than 10 of these tumour lesions through the whole study period (3 years). Endoscopic ultrasonography was performed in 283 cases (53 %); the rate of neoadjuvant treatment was 34.4 % (n = 187). Intraoperative fresh frozen section was only included in intraoperative decision-making in 242 patients (60.8 %). In the revealed heterogeneous spectrum of surgical interventions, a limited number of transthoracic approaches (20 %) and a mediastinal lymphadenectomy rate of only 47 % were found. Hospital lethality was 6.6 %. In the adenocarcinomas of the oesophagogastric junction, a significantly lower median survival (25 months) compared with distal gastric cancer (38 months) was observed depending on the tumour stage. In addition, 5-year survival rate of AEG patients (33.1 %) was distinctly lower than for patients with distal gastric cancer (41.4 %). There was no significantly better survival by neoadjuvant treatment in the group of investigated patients.ConclusionThe results in the treatment of carcinomas of the oesophagogastric junction in the multicentre setting including surgical departments of each profile and region even after introduction of multimodal therapeutic concepts are not satisfying. In particular, modern diagnostic and surgical strategies need to be widely used or their percentage has to be increased. In this context, centralisation of the surgical care of this specific tumour entity appears reasonable.Georg Thieme Verlag KG Stuttgart · New York.
