Superselective intra-arterial chemotherapy with mitomycin C in hepatic neoplasms.

The results of superselective intra-arterial chemotherapy with Mitomycin C (SIAC) in cases of hepatic neoplasms continue to be poor. Survival time was related to the percentage of hepatic replacement (PHR) but only 19% of the patients with Stage I tumours (PHR < 25%) survived for over 5 years and all the others died within 4 years. The patients with hepatic metastases from colorectal cancer achieved a significantly better cumulative 5-year survival figure than those with hepatocellular cancer (P < 0.05). The median survival times for patients with hepatic metastases from colorectal cancer, hepatocellular cancer and gallbladder cancer were 15 months, 6 months and 13 months, respectively. The overall response rate was only 27% (26/97), that for primary liver cancer 20% (7/35), that for hepatic metastases from colorectal cancer 22% (8/37) and that for gallbladder cancer 44% (11/25) and the patients who responded to SIAC (n = 27) had a significantly better cumulative 5-year survival rate (P < 0.005). Cessation of SIAC was necessary in 74% (72/97) of the cases, because of tumour progression in 53% (51/97), major complications in 19% (18/97) and patient refusal in 3% (3/97). The results of this trial may be regarded as disappointing, and we are going to use SIAC for Stage I tumours only. Resection of the tumour continues to provide the only chance of a permanent cure with these patients.
