Hyperthermo-chemo-hypoxic isolated liver perfusion for hepatic metastases: a possible adjuvant approach.
As a possible intraoperative adjuvant approach to treating hepatic metastases we developed a method of hyperthermo-chemo-hypoxic isolated liver perfusion in combination with hepatic resection. This method was applied to 11 patients with colorectal hepatic metastases between 1992 and 1995. One patient died on postoperative day 14 of hepatic failure (9% mortality), the cause of which was live temperature that reached 42.9 degree C, which seems to be the maximum limit for thermal toxic effect on the human liver. The other 10 patients tolerated the perfusion well, with mild hepatic and non systemic toxicity after minor or even major hepatic resection; the serum aminotransferase and total bilirubin levels returned to normal levels by postoperative day 14. Only one of eight patients (13%) for whom cytotoxic drugs were added to the perfusate (mitomycin C 10 micrograms/ml or cisplatin 2 micrograms/ml) had hepatic recurrence by 19 months after the perfusion (mean follow-up 25.8 months; median 23 months; range 8-57 months). Two patients were alive with no evidence of disease at 13 and 57 months, respectively after the perfusion; the other five patients had postperfusion extrahepatic recurrences (median: 19 months; range 7-20 months). In contrast, hepatic metastases recurred 7 and 20 months after the perfusion, respectively, in the two patients not given a cytotoxic drug.
