Tissue toxicity in experimental isolated perfusion with adriamycin.
Summary
Isolated limb perfusion with Adriamycin is effective for cancer treatment. Dosages up to 10 mg/l are safe, but higher concentrations cause severe side effects like edema and pain in dogs.
Area of Science:
- Oncology
- Pharmacology
Background:
- Adriamycin (doxorubicin) is a potent antineoplastic agent used for various human cancers.
- Isolated limb perfusion (ILP) is a regional chemotherapy technique.
Purpose of the Study:
- To determine the maximum tolerated concentration of Adriamycin during isolated extremity perfusion.
- To evaluate the safety and side effects of varying Adriamycin dosages in ILP.
Main Methods:
- The hind legs of 12 dogs were isolated and perfused using an extracorporeal circuit under normothermic conditions.
- Adriamycin was administered at different concentrations to assess tolerance.
Main Results:
- Concentrations of approximately 10 mg/l of Adriamycin were well-tolerated.
- Higher dosages exceeding 10 mg/l frequently resulted in severe edema, pain, and histological damage.
Conclusions:
- The maximum tolerated concentration of Adriamycin in isolated limb perfusion for canine extremities is around 10 mg/l.
- Higher doses carry a significant risk of local toxicity and adverse effects.
