SummaryBackgroundRecurrence of hepatocellular carcinoma (HCC) after surgery is frequent, and is an important factor adversely influencing the long-term survival of patients. This prospective study evaluated whether adjuvant chemotherapy with oral tegafur/uracil (UFT) reduces the recurrence rate of HCC. In addition, expression of thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) were investigated in resected tumors and nontumorous tissues, and the relationship between their expression and the effectiveness of UFT was examined.MethodsA total of 117 patients who underwent curative hepatic resection for HCC were randomly allocated to UFT 400 mg/d (n = 24, UFT group) or surgery alone (n = 56, control group). The primary endpoint was the recurrence-free survival rate, and the secondary endpoint was the overall survival rate. Expression of the DPD and TS genes were quantified with TaqMan reverse transcription-polymerase chain reaction assay using β-actin as an internal standard. The cut-off value was set at the mean value of TS and DPD expression.ResultsAmong the 61 patients in the UFT group, 37 patients (60.6%) discontinued UFT within 1 month. Recurrence-free survival (p = 0.16) and overall survival (p = 0.29) were similar in the two groups. In the UFT group, recurrence-free survival did not differ significantly between high-TS (TS > 3.6) and high-DPD (DPD > 8.9; n = 10), and low-TS (TS ≤ 3.6) and low-DPD (DPD ≤ 8.9; n = 9) groups. However, there was a significant difference between the two groups in overall survival (p = 0.04).ConclusionPeroral UFT administration fails to prolong the recurrence-free rates and overall survival rates, in comparison with surgery alone. However, oral administration of UFT may improve the survival of HCC patients when the levels of TS and DPD mRNA are low in the tumor tissue.
