Abstract

Purpose

Hematogenic metastasis of patients with colorectal cancer most frequently effects the liver; the prognosis of affected patients is dramatically worsened by the presence of this lesion. The aim of this study was to evaluate the effect of hepatic arterial chemoembolization (HACE) with irinotecan versus 5-fluorouracil as a standard agent in a rat liver metastasis model.

Materials and methods

Diffuse liver metastasis was induced by injecting 4×106 CC531-lac-Z rat colorectal carcinoma cells into the portal vein of male Wag/Rij rats. Irinotecan (10 mg/kg, 30 mg/kg, and 60 mg/kg) and 5-fluorouracil (40 mg/kg, 60 mg/kg, and 90 mg/kg) were administered concomitantly with degradable starch microspheres (30 mg/kg) for temporary embolization. The tumor cell load was determined quantitatively using a chemoluminescence assay.

Results

HACE with irinotecan induced a complete remission in 44% of the animals and the highest dose reduced the mean tumor cell load by 66% (P <0.001). In contrast, the highest dose of 5-FU caused a reduction of only 18% (P = 0.026) and altogether 23% complete remissions were observed in response to 5-FU. The sensitivity of CC531-lac-Z cells versus irinotecan (IC50 32 pM after 72 h) and 5-FU (IC50 80 µM) mirrored the effects observed in vivo on a qualitative basis.

Conclusion

In conclusion, the effect of HACE with irinotecan surpassed that of HACE with 5-FU and prompts further investigation in clinical trials.

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
