Abstract
Background
The prognosis of advanced hepatocellular carcinoma (HCC) remains poor, particularly in patients with tumor thrombi (TT) in the major vessels.
Patients and Methods
From July 1992 to October 2004, 161 patients diagnosed as having advanced HCC with major vascular involvement were seen consecutively at our hospital. Among these patients, 32 (20%) underwent surgical resection [16 complete resection (CR), 16 reductive resection (RR)]. Eighteen patients (11%) received radiotherapy (RT), 73 (45%) underwent transcatheter arterial chemoembolization (TACE) or transcatheter arterial infusion chemotherapy (TAI), 8 (5%) with distant metastases received systemic chemotherapy, and 30 (19%) received palliative therapy.
Results
Excluding the CR group, the patients in the RR group had a higher 1-year survival rate than the other treatment groups. However, there was no significant difference in the overall survival rates of the RR, RT, and TACE/TAI groups. When we evaluated prognostic factors to clarify the indications for RR in the multidisciplinary treatment of patients with advanced HCC with TT, prothrombin activity (PA) was identified as a significant independent preoperative factor for overall survival in the RR group. The survival rate in patients with PA of ≤78% was significantly lower than that of patients with PA of >78% (P = 0.0004). The median survival time of patients with serum PA of >78% who underwent RR was 13.9 months and that of patients who underwent CR was 9.1 months, with no survival difference between the groups.
Conclusion
In advanced HCC with major vascular involvement, patients who had RR with PA of greater 78% achieved a similar survival to those who had CR. The surgeon should still proceed with RR in those patients with serum PA of >78% if CR does not seem feasible on preoperative evaluation.
