Efficacy of combined use of sodium thiosulfate in percutaneous isolated liver chemoperfusion of cisplatin under complete hepatic venous isolated and charcoal hemoperfusion

We herein evaluated the efficacy of combined use of sodium thiosulfate (STS) in isolated liver chemoperfusion of cisplatin (CDDP) under complete hepatic venous isolation and charcoal hemoperfusion (HVI.CHP). Dogs were divided into two groups; group I (n = 5), CDDP (4 mg/kg) + STS (4 g/body) and grou...

Summary:We herein evaluated the efficacy of combined use of sodium thiosulfate (STS) in isolated liver chemoperfusion of cisplatin (CDDP) under complete hepatic venous isolation and charcoal hemoperfusion (HVI.CHP). Dogs were divided into two groups; group I (n = 5), CDDP (4 mg/kg) + STS (4 g/body) and group II (n = 5), CDDP (4 mg/kg). In both groups, CDDP was intraarterially administered for 20 minutes under HVI.CHP. In addition, in group I, STS infusion was administered for 20 minutes via the outlet side of CHP filter. The adsorption rates of free and total CDDP of CHP filter were in a range of 50-80%, and the rates in group I were higher than in group II. At all sampling points, the AUC (microgram.min/ml) of free CDDP was not different between the two groups. However, the AUC of total CDDP at postfilter [group I: 35.3 +/- 2.7 (mean +/- SD); group II: 63.5 +/- 21.5] and systemic serum (group I: 24.9 +/- 8.6, group II: 43.5 +/- 13.5) was significantly lower in group I than in group II (p < 0.05). The cumulative amounts of urinary excretion of CDDP (microgram/kg) were 39.5 +/- 12.1 and 13.5 +/- 9.3 in groups I and II, respectively, showing a significant increase in group I (p < 0.01). These results indicated that the use of STS in percutaneous isolated liver chemoperfusion of CDDP under HVI.CHP could further reduce systemic toxicities of CDDP, by increasing CDDP filter extraction of CHP filter and urinary CDDP excretion.
