BACKGROUND: Cholangiocarcinoma (CCA) is an adenocarcinoma of the hepatobiliary system, which can be classified into intrahepatic (iCCA), perihilar (pCCA) and distal (dCCA). Surgical resection is the curative treatment for all subtypes of CCA. This study evaluates patients with CCA who underwent surgery and determines factors that impact their survival.
METHODS: We conducted a retrospective analysis of 720 patients diagnosed with CCA from October 2013 to December 2018. Patients were categorized into iCCA (n = 398), pCCA (n = 237), and dCCA (n = 85) based on tumor location. Data including demographic information, clinical presentation, treatment modalities, and survival statistics were collected and analyzed.
RESULTS: The overall resectability rate was 78.3%, with resectability highest in pCCA patients (83.5%). Overall median survival time (MST) was 11.6 months and varied among subtypes: iCCA 10.9 months, pCCA 11.2 months, and dCCA 15.4 months. Patients underwent curative-intent resection significantly improved survival compared to those with palliative resection or unresectable disease in all subtypes. R0 resection patients had better overall survival (OS) than R1 resection patients: 5-year survival rate of 20.2% vs. 4.3% in all CCA (p < 0.001), 21.4% vs. 7% in iCCA (p < 0.001), 17.2% vs. 0% in pCCA (p < 0.001), and 23.1% vs. 0% in dCCA (p = 0.105), respectively. Positive resection margin was an independent prognostic factor for OS in pCCA and iCCA.
CONCLUSION: Surgical resection is the only cure for CCA. Curative-intent resection is more effective than palliative resection in improving survival rates. When performing curative-intent resection, the goal is R0 resection. This is because it improves overall survival over R1 resection.
