Predictability of esophagus- and cardiatumor resectability by preoperative computed tomography.

Prior to operation, 32 patients with a tumor in the esophagus or in the cardia region were examined with computed tomography (CT), to evaluate the predictability of tumor resectability by CT. Twenty patients had the tumor operatively resected, in 2 patients the bulk of tumor could only be partly resected, and 10 patients were non-resectable due to invasion into the surrounding structures. The tumor resectability evaluated by preoperative CT resulted in positive/negative predictive values of 91 and 90%, respectively. This indicates that CT is a valuable method in planning the therapeutic strategy in cases of carcinoma of the oesophagus and the cardia region. The predictability of lymph-node involvement in the mediastinum and abdomen was less convincing.
