Abstract:
PURPOSE:To analyze the clinical outcomes of chemoembolization for solitary caudate lobe hepatocellular carcinoma (HCC) found at initial presentation. MATERIALS AND METHODS:This retrospective study was approved by the institutional review board; the requirement for informed patient consent was waived. From July 1998 to June 2009, 40 patients (28 men, 12 women; mean age, 57 years) found to have a single HCC lesion in the caudate lobe at initial presentation were treated with chemoembolization and evaluated for overall survival and progression-free survival. Multivariate analyses for potential clinical and radiologic factors were performed by using the Cox proportional hazard model. RESULTS:Selective chemoembolization via the caudate artery was achieved in 34 (85%) patients. Overall survival rates at 1, 2, 3, 4, and 5 years were 92%, 79%, 65%, 56%, and 56%, respectively. Selective chemoembolization of the caudate artery was a critically important factor in longer overall survival (hazard ratio, 0.091; 95% confidence interval [CI]: 0.021, 0.389; P < .001), and portal vein tumor thrombosis (hazard ratio, 31.25; 95% CI: 4.88, 200.1; P < .001) and multiple tumor-feeding vessels (hazard ratio, 6.87; 95% CI: 1.47, 32.1; P = .014) were significant factors in shorter overall survival. Selective chemoembolization of the caudate artery was also a significant factor in longer progression-free survival (hazard ratio, 0.278; 95% CI: 0.10, 0.76; P = .013). CONCLUSION:Selective chemoembolization via the caudate artery is possible in most patients with caudate lobe HCC and a critical factor in longer overall survival and longer progression-free survival.
