Serum levels of bleomycin released from the lymphatic system

Endolymphatic injection Oil-Bleo (Nippon Kayaku, Japan) was performed on 24 patients for treatment of residual retroperitoneal malignant lymphoma detected after intravenous chemotherapy. The drug was administered once only in a dosage of 60 mg/30 mg per foot. Serum levels of the drug were monitored. The results were compared with data obtained after routine intravenous infusion of aqueous bleomycin to patients with advanced cervical cancer. The results revealed that bleomycin administered intralymphatically reaches maximum concentration after 15 minutes, and bleomycin after intravenous administration reaches maximum concentration at 36 hours.
