OBJECTIVE: To investigate risk factors associated with mortality in cholangiocarcinoma patients receiving surgical treatment in Thailand's endemic area and their survival rate.
MATERIALS AND METHODS: Medical records of patients with histologically confirmed cholangiocarcinoma, who underwent surgical treatment at Sanpasitthiprasong Regional Hospital from October 1, 2013 to October, 31 2015, were retrospectively included. Patients' vital status (death/alive) and date of death were obtained from the Interior Ministry's death certificate. Cox proportional hazard regression was used to examine factors associated with mortality.
RESULTS: Out of 295 patients with cholangiocarcinoma (CCA), 180(58%) were intrahepatic CCA, 86(28%) were perihilar CCA, and 29 (9%) were distal CCA. Three groups were homogenous in terms of age and gender. Most of our patients referred with abdominal pain (63%), especially those who were intrahepatic CCA (77%). However, almost 80% of the perihilar CCA and distal CCA patients came with jaundice. Tumor markers (CEA and CA19-9) were not different between groups p=0.74 and p=0.43 respectively. Median survival of patients with intrahepatic CCA, perihilar CCA, and distal CCA patients was 14.6, 14.2, and 14.0 months, respectively. Factors independently associated with mortality in intrahepatic CCA patients were number and size of tumors and presence of perineural invasion (Hazard ratio (HR) 1.09[1.03 - 1.15], 1.07[1.02 - 1.13], and 2.09 [1.28 - 3.39], respectively). In perihilar CCA patients, having positive lymph nodes and resection status were independently associated with mortality. Compared to R0 resection, R1, R2, and no resection of perihilar CCA were associated with a 2-, 8- and 4-fold increase in the risk of mortality (HR 2.17 (0.99 - 4.78), 7.97 (3.22 - 19.71), and 4.21 (0.51 - 34.82), respectively).
CONCLUSION: CCA patients in this endemic area had fairly poor survival. Factors associated with mortality in intrahepatic CCA were number and size of tumors and perineural invasion. However, risk factors for perihilar CCA included positive lymph nodes and resection status.
