Surgical treatment for carcinoma of the gastric cardia: a modified proximal esophagogastrectomy.
Proximal esophagogastrectomy saving only the distal half of the greater curvature of the stomach was retrospectively evaluated in 91 consecutive patients with resectable carcinoma of the gastric cardia. Division of the right gastric artery at its beginning provided a free nodal margin if N1 diffusion was observed. Operative mortality was 6.5% and fatal leak rate 3.8%. Survival without dysphagia occurred in all but stage I tumors; for larger tumors recurrence and reflux esophagitis were not able to produce dysphagia because distant metastases were faster to kill the patients. Five-year survival was 0% for stage IV (i.e. incomplete macroscopic resection), 8% for stage III, 12% for stage II and 53% for stage I. Local recurrence occurred only at esophageal anastomosis and for every stage, whereas regional recurrence occurred only for tumors with nodal diffusion. The results of this study are not suitable for a comparison with total esophagogastrectomy by inductive logic, nevertheless deductive arguments are possible if patterns of recurrence are considered. The possibility of regional recurrence for N1 and not for N0 tumors means that the volume of nodal resection has diagnostic specificity for N0 but not for N1 tumors. If N2 nodal diffusion is really a sistemic disease, as indicated by current reports, than greater nodal resection by total esophagogastrectomy can only improve the diagnostic specificity of N1 assessment but not survival.
