Objective: To investigate liver fibrosis, TGF-${\beta}1$ levels and curative effects on hepatocellular carcinoma (HCC) with small and conventional dose perfusion chemotherapy by transcatheter arterial chemo embolization (TACE). Methods: Thirty-six hepatocellular carcinoma patients not indicated for surgical resection underwent super-selective transcatheter arterial chemoembolization, divided into small dose (n=15) and conventional dose (n=21) chemotherapy groups. Results: With conventional doses, four indices of liver fibrosis focusing on hyaluronate acide (HA), human procollagen type-III (hPC-III), collagen type-Ⅳ (Ⅳ-C) and transforming growth factor-${\beta}l$ (TGF-${\beta}1$) were obviously increased postoperative compared with preoperative (P<0.01); in contrast, with small doses there were no significant differences except for TGF-${\beta}1$. Five year survival demonstrated no significant differences between the two groups (P>0.05). Conclusion: To hepatocellular carcinoma patients treated by TACE, reducing doses of chemotherapy drugs can reduce progress of liver fibrosis, without impacting on five year survival.

Objectives: To explore the impact of low- vs conventional-dose chemotherapy via transcatheter arterial chemo-embolization (TACE) on serum fibrosis indicators and treatment efficacy of hepatocellular cancer patients (HCC). Materials and Methods: Patients fulfilling the eligibility criteria were assigned to TACE in Group A (with low-dose chemotherapy) or Group B (conventional-dose chemotherapy). Four serum fibrosis related indicators, hyaluronic acid(HA), human pro-collagen type-III (hPC-III), laminin (LN), and collagen type-IV(IV-C) before TACE were compared with the values 7 days after TACE. The response rate and survival time were also compared between the two groups. Results: Fifty patients with HCC were enrolled in this study, including 25 in Group A and 25 in Group B. No significant differences were detected between the two groups in the four indicators before TACE. After TACE, the value of the four serum indicators increased significantly in Group B. However, no significant differences regarding these four indicators were found in Group A after TACE. Significant differences were demonstrated between the two groups after TACE, but median survival time and 1 or 2 year overall survival rates did not differ (P>0.05). Conclusions: Low-, compared with conventional-dose chemotherapy exerts the same impact on the variation of fibrosis related indicators and has no influence on median survival time and survival rate after TACE in HCC patients.
