[Four Cases Who Experienced Extravasation of Anthracyclines and Had Dexrazoxane Therapy].

We analyzed 4 cases who experienced extravasation of anthracyclines and had dexrazoxane therapy in our hospital. Concerned drugs were 2 adriamycin and 2 amrubicin cases and all cases received steroid ointment therapy, and no cases showed severe condition such as skin ulcer. As dexrazoxane is known to enhance bone marrow suppression of anti-cancer drugs, the nadir of neutropenia and thrombocytopenia was observed from day 10 to 17 in our cases.

Evaluation for pharmacokinetic exposure of cytotoxic anticancer drugs in elderly patients receiving (R-)CHOP therapy.

(R-)miniCHOP therapy, which delivers approximately half-doses of the (R-)CHOP regimen, has shown efficacy and safety in patients who are more than 80 years old. This study aimed to compare the area under the plasma concentration-time curves (AUCs) of vincristine (VCR), doxorubicin (DXR), and cyclophosphamide (CPA) between (R-)CHOP and (R-)miniCHOP regimens. The AUCs were compared between patients aged 65-79 years receiving (R-)CHOP therapy and those aged 80 years and older receiving (R-)miniCHOP therapy.
