Gastric cancer in the reconstructed gastric tube after radical esophagectomy: a single-center experience.

PURPOSE

Metachronous gastric carcinoma arising in a gastric tube used for esophageal reconstruction has been occasionally encountered in long-term survivors of esophageal cancer. This study investigated 10 cases of gastric tube cancer in order to clarify the characteristics and the outcome of these patients.

METHODS

Four hundred and seventy-one patients underwent a radical esophagectomy at Kyushu University Hospital between 1989 and 2003. There were 10 cases of gastric tube cancer after an esophagectomy.

RESULTS

The interval between the esophagectomy and the development of the gastric tube cancer ranged from 1.1 to 7 years. There was no peak for the incidence of gastric tube cancer. In 6 of 10 cases of gastric tube cancer, endoscopic or surgical resection were performed for the treatment; however, chemotherapy was administered to the other 4 cases for several reasons. The prognosis of patients who underwent resection was better than that of the other patients.

CONCLUSIONS

Frequent endoscopic examinations are therefore important even several years after performing an esophagectomy, since the risk of gastric tube cancer is higher than the risk of a recurrence of esophageal cancer several years after an esophagectomy. Only an early diagnosis permits a less invasive and appropriate approach for the treatment of gastric tube cancer.
