1 Anthracycline induced Cardiomyopathy AM Report December 11 2009 AM Report December 11 2009

2 Chemotherapy and Cardiotoxicity Anthracyclines Herceptin Antimetabolites 5-fluorouracil - coronary vasospasm Fludarabine - high dose for BMT conditioning Vinca alkaloids - hypertension, myocardial ischemia Taxanes - conduction abnormalities Cyclophosphamide - cardiomyopathy Bleomycin - pericarditis Mitomycin C - heart failure Monoclonal antibodies Anthracyclines Herceptin Antimetabolites 5-fluorouracil - coronary vasospasm Fludarabine - high dose for BMT conditioning Vinca alkaloids - hypertension, myocardial ischemia Taxanes - conduction abnormalities Cyclophosphamide - cardiomyopathy Bleomycin - pericarditis Mitomycin C - heart failure Monoclonal antibodies

3 History of Anthracycline use Fermentation product of Streptomyces peucetius Daunomycin and doxorubicin devolped in 1960s Clinical Uses breast and esophageal carcinomas osteosarcoma, Kaposi's sarcoma and soft- tissue sarcomas Hodgkin's and non- Hodgkin's lymphomas Fermentation product of Streptomyces peucetius Daunomycin and doxorubicin devolped in 1960s Clinical Uses breast and esophageal carcinomas osteosarcoma, Kaposi's sarcoma and soft- tissue sarcomas Hodgkin's and non- Hodgkin's lymphomas Doxorubicin

4 Mechanism Therapuetic Intercalating between base pairs of the DNA/RNA Inhibits topoiosomerase II enzyme Cardiotoxicity Production of toxic oxygen ハ free radicals and an increase in oxidative stress Loss of myofibrils and the vacuolization of cytoplasm Therapuetic Intercalating between base pairs of the DNA/RNA Inhibits topoiosomerase II enzyme Cardiotoxicity Production of toxic oxygen ハ free radicals and an increase in oxidative stress Loss of myofibrils and the vacuolization of cytoplasm

5 Risk Factors - Cumulative dose

6 Risk Factors Age 70 years of age Previous/Concurrent Radiation Concomitant chemotherapy Herceptin and taxols Bone Marrow Transplant Cardiac Risk Factors Age 70 years of age Previous/Concurrent Radiation Concomitant chemotherapy Herceptin and taxols Bone Marrow Transplant Cardiac Risk Factors

7 Clinical Manifestations Acute - during infusion to 1 week Arrhythmias Ventricular dysfunction Pericarditis/myocarditis Early - < 1 year Dose-related cardomyopathy Late Acute - during infusion to 1 week Arrhythmias Ventricular dysfunction Pericarditis/myocarditis Early - < 1 year Dose-related cardomyopathy Late

8 Monitoring Serial noninvasive monitoring of LVEF Radionuclide angiography (MUGA) Echocardiography Exercise stress radionuclide ventriculography Biomarkers Serum troponins BNP/pro-BNP Endomyocardial Biopsy Serial noninvasive monitoring of LVEF Radionuclide angiography (MUGA) Echocardiography Exercise stress radionuclide ventriculography Biomarkers Serum troponins BNP/pro-BNP Endomyocardial Biopsy

9 Monitoring Normal EF Baseline (prior to 100 mg/m2) 2 nd study after 250 to 300 mg/m2 3 rd at 400-450 mg/m2 Sequential studies prior to each additional dose EF 30-50% EF study prior to each dose EF < 30% - recommend against initiating Discontinue doxorubicin for decrease in EF >10% or absolute < 30% Normal EF Baseline (prior to 100 mg/m2) 2 nd study after 250 to 300 mg/m2 3 rd at 400-450 mg/m2 Sequential studies prior to each additional dose EF 30-50% EF study prior to each dose EF < 30% - recommend against initiating Discontinue doxorubicin for decrease in EF >10% or absolute < 30%

10 Prevention Altering infusion protocol Alternate anthracycline derivatives Liposomal preparations Dexrazoxane - metal-chelating agent Beta-blockers ACE inhibitors Altering infusion protocol Alternate anthracycline derivatives Liposomal preparations Dexrazoxane - metal-chelating agent Beta-blockers ACE inhibitors

11 Prognosis and Treatment Prognosis Mortality rates of > 30% in early studies Treatment ACE inhibitors Traditional Heart failure Management Heart Transplant Prognosis Mortality rates of > 30% in early studies Treatment ACE inhibitors Traditional Heart failure Management Heart Transplant
