Study	Reason for exclusion
Bao 2001	A randomised trial of 40 patients which compared the effectiveness of hydroxycamptothecin and mateling versus Cis‐Platinum diamminedichloride (PDD) and 5‐Fluorouracil postoperatively (after curative resection of hepatocellular carcinoma) as arterial infusion.
Ikeda 2000	A small trial of 20 patients with surgical resection of HCC or percutaneous ethanol injection therapy were randomised to a control or adjuvant therapy group. Ethanol injection therapy is not a generally accepted method and therefore the patients does not meet the inclusion criteria for this review. We will try to contact the authors to obtain more information about the outcomes of patients who underwent resection.
Li 2002	A randomised trial of 45 patients which compared the effectiveness of route of administration of chemotherapy. The comparison was postoperative intraarterial and intraportal chemotherapy versus intraarterial chemotherapy alone.
Muto 1996	Control group comprised an unknown proportion of surgical resection and percutaneous ethanol injection cases. Concerned with prevention of onset of second primary tumours and not absolute survival from secondary tumours of the resected primary.
