One Year Survival of Extrahepatic Cholangiocarcinoma Patients Who Did Not Undergo Curative Resection and Paliative Chemotherapy and Its Associated Factors

Abstract

Background: Extrahepatic cholangiocarcinoma is rare but fatal. Patients who come are usually already in the advanced stage that can not undergo curative resection and chemotherapy also seems to be very rarely done. The survival rate and its associated factors in Indonesia are unknown. This study aimed to identify 1-year survival of patients with extrahepatic cholangiocarcinoma without curative resection and palliative chemotherapy and its associated factors. Methods: This is a cross-sectional study using medical records of extrahepatic cholangiocarcinoma (perihilar and distal) inpatient and outpatient patients at Cipto Mangunkusumo Hospital, Jakarta from January 2015 to March 2020, reviewed retrospectively. The following factors were analyzed in terms of mortality: metastasis, sepsis, hypoalbuminemia, serum bilirubin level, serum CA 19-9 level, billiary drainage, neutrophyl lympocyte ratio (NLR) and comorbid factors. Results: 115 out of 144 patients were enrolled in this study with male proportion of 50.4%, and proportion of patients aged 65 years or above was 71.3%. 1 year survival rate was 10 % and median survival was 3 months (CI 95% 2.388-3.612)Multivariate analysis showed that only sepsis, unsuccessful or no prior biliary drainage and total bilirubin >19.8 mg/dl were independent predictors of mortality. Conclusion: 1 year survival of extrahepatic cholangiocarcinoma without curative resection and paliative chemotherapy was 10 %.Sepsis, unsuccessful or no prior bilirary drainage, and total biirubin >19.8 mg/dl are factors significantly associated with shortened survival in malignant obstructive jaundice patients.
