Abstract
Objective To investigate the efficacy of preoperative transcatheter artery chemoembolization (TACE) correlates with outcome after orthotopic liver transplantation (OLT) in patients with hepatocellular carcinoma (HCC). Methods Sixty-seven patients with HCC underwent TACE before OLT. In all the patients, there were 52 males and 15 females with age ranging from 34 to 67 years old (average 48). Sixty-one patients met the Milan' standard, and 6 patients exceeded Milan' standard. Classic OLT was done in 62 patients and pigyback liver transplantation was done in 5 patients. Immunosuppression regimen after operation included Tacrolimus (or Ciclosporin,Sirolimus), mycophynolate, steroid hormone. The efficacy of TACE was assessed according to histological findings after OLT. Tumor recurrence rate of 1-and 2-year tumor recurrence rate, and 1-and 2-year survival rate in different groups with different responses to preoperative TACE were compared. Results Tumor necrosis rate was greater than 50% in 50 patients and new tumor nodi occurred in 2 patients. Tumor necrosis rate after TACE was 73. 77%. Tumor necrosis rate was less than 50% in 17 patients and new tumor nodi occurred in 7 patients. Forty-eight patients had satisfactory efficacy after TACE and no new tumor nodi occurred, 1-and 2-year tumor recurrence rate was 2. 08/ (1/48) and 6. 25% (3/48) respectively, and 1- and 2-year survival rate was 97. 92% (47/48) and 95. 83% (46/48) respectively. Nineteen patients had worse efficacy after TACE and new nodi occurred, 1- and 2-year tumor recurrence rate was 36. 84% (7/19) and 57. 89% (11/19), and 1-and 2-year survival rate was 73.68% (14/19) and 47. 37% (9/19) respectively. There were statistically significant difference between the two groups (P＜0.05). Conclusion TACE provides good local control in preoperatively diagnosed HCC, but its impact is limited in lesions not detected preoperatively. Patients with satisfactory efficacy after TACE before OLT had a good prognosis. The response to preoperative TACE may predict long-term outcome after LT.
