PURPOSE: Free cancer cells exfoliated from cancer-invaded serosa contribute to peritoneal dissemination, the most frequent pattern of recurrence in patients with gastric cancer. To detect free cancer cells, CEA and CA19-9 were introduced as the markers of gastric cancer, and many methods, such as cytology, immunoassay, and reverse transcription polymerase chain reaction (RT-PCR), exist for detecting them. The aim of this study is to define the clinical significance of using immunoassay to measure the levels of CEA and CA19-9 in the peritoneal washings in patients with gastric cancer. MATERIALS AND METHODS: The peritoneal washing fluids were obtained from 130 patients with gastric cancer who received a curative gastrectomy, palliative gastrectomy or open and closure. The pCEA and pCA19-9 levels were measured by using immunoassay and cytology. The results were compared with the clinicopathological data. RESULTS: The pCEA and pCA19-9 levels were correlated with tumor invasion, lymph-node metastasis, and stage (P<0.05). CONCLUSION: A correlation was found between elevated pCEA and pCA19-9 levels measured by immunoassay and the TNM stage. Therefore, a combined pCEA and pCA19-9 assay could be a sensitive detector of peritoneal dissemination, as well as a predictor of postoperative prognosis. pCEA and pCA19-9 may also determine the adjuvant management strategy.

BACKGROUND/AIMS: Recently, living donor liver transplantation (LDLT) has been frequently performed in Korea because of the limited availability of a cadaveric donor (CD). We evaluated the clinical features of patients with biliary complications after liver transplantation and we compared the incidence of biliary complications according to the type of donor and the anastomotic type of the biliary tract. METHODS: Between May 1996 and July 2004, 300 patients (CDLT 102/LDLT 198) underwent liver transplantation at Samsung Medical Center. The patients who experienced biliary complications during the follow-up period were enrolled to the study and we retrospectively reviewed their cases. RESULTS: Sixty-seven cases (23%) of biliary complications were noticed in 53 patients (18%). The complications consisted of 20 cases (7%) of bile leakage, 38 cases (13%) of biliary strictures, 7 cases (2%) of biliary stones, and 2 cases (1%) of biliary stenosis due to other cause. There was no significant difference on the incidence of complications between CDLT (15/102; 14.7%) and LDLT (38/198; 19.2%) (p=0.42). In addition, there was no significant difference between choledocho-choledochostomy (43/237; 18.1%) and hepatico-jejunostomy (10/ 63; 15.9%)(p=0.85) CONCLUSIONS: The incidence rate of biliary complication after liver transplantation was 23%, and there was no difference according to the type of donor and the anastomotic type of biliary tract.
