The original version of this article contained an error in Fig. 6A. The volumes of the tumour xenografts were incorrectly calculated. The correct figure and figure legend are below, where the volume has been calculated using V = length × width2 × π/6. The interpretation of the data and conclusions are not affected.

CPT sensitized HCC xenografts to EPI treatment. Nude mice were injected with SMMC-7721 cells. CPT, Camptothecin; EPI, epirubicin. Mice were treated with CPT, EPI or in combination (COM) twice a week for a total of three times. At the end of the experiments, tumours were excised and weighed at the end of the experiment. a Tumour growth curves for SMMC-7721 xenografts. b Representative images of excised tumours. c Excised xenograft tumours weights at the end of the experiment. n = 8–10; *p < 0.05 vs. Veh control. #p < 0.05 vs EPI
