3D conformal radiotherapy combined with transcatheter arterial chemoembolization for hepatocellular carcinoma

Figure 1 Route and results of including trials in the meta-analysis.

Figure 2 Outcomes of overall survival of combination therapy compared with sole transcatheter arterial chemoembolization therapy alone.

Figure 3 Better tumor response and higher decline in α fetal protein level were shown in patients treated with combination therapy.

Figure 4 No significant asymmetry was revealed in 1-year (A), 2-year (B) and 3-year (C) overall survival.

Figure 5 No publication bias was found in tumor response (A) and reduction in α fetal protein level (B).
