Gastric adenocarcinoma after renal transplantation.

Abstract

Background/Aims: Little is known of the characteristics of gastric adenocarcinoma after renal transplantation. This study was performed to find out the incidence and clinicopathulogical features of gastric adenocarcinoma after renal transplantation in an endemic area for gastric cancer. Methodology: Between April 1979 and March 2001, fourteen gastric adenocarcinoma patients (0.7%) out of 2000 renal transplant recipients in a single institute were retrospectively reviewed. Results: Gastric adenocarcinoma was identified in Gastric adenocarcinoma 14 recipients (8 males and 6 females, mean age 47.6 years) about 60 months after renal transplantation. Four patients had early gastric cancer, ten patients had cancer in an advanced stage. Eleven patients underwent surgical resection, while three with distant metastasis were treated symptomatically. There was no postoperative mortality. Seven patients survived without evidence of recurrence, whereas four died of recurrence and three of gastric cancer progression. Conclusions: Renal transplant recipients are at increased risk of gastric adenocarcinoma, the most common malignancy in Korea. With curative surgery, favorable prognosis can be anticipated when the diagnosis is made at an early stage. Regular endoscopic examination for early diagnosis is recommended during the follow-up period after renal transplantation in a gastric cancer endemic area.
