摘要
Background: The CA 19-9 tumour marker is increasingly used to monitor response to therapy in patients with pancreatic adenocarcinoma. Serum CA 19-9 levels have also been shown to correlate with survival. However, their role in cholangiocarcinoma is less clear. Aim of study: To assess the utility of CA 19-9 levels in the management of patients with advanced pancreatic adenocarcinoma or cholangiocarcinoma in routine clinical practice is the aim of the study. Methods: A retrospective analysis of CA 19-9 values and survival was performed in 26 patients with pancreatic adenocarcinoma receiving gemcitabine and in 18 patients with cholangiocarcinoma. Results: Patients with advanced pancreatic adenocarcinoma receiving gemcitabine who experienced a decrease of 20% in CA 19-9 concentration had a median survival of 13.9+ months (range 4.2-23.5) compared to 7.6+ months (range 4.0-14.7) in those without such a change (p∈=∈0.0109). In patients with advanced cholangiocarcinoma, the median survival was longest in those with a baseline CA 19-9 level of less than 1,000 U/ml; 11.8 months (range 1.0-41.4) vs 6.2 months (range 3.1-9.4; p∈=∈0.0075). Conclusions: The CA 19-9 concentration has a valuable role in predicting outcome in patients with pancreatic adenocarcinoma and cholangiocarcinoma. It is helpful in guiding therapy and should be used accordingly in oncology practice. © 2008 Humana Press Inc.
