Why discuss cardiac disease and cancer? Let’s consider…
• These are by far the two most common disease conditions in the developed world
• Cardiac disease may pre-exist cancer therapy or may be caused/exacerbated by it
• Cancer therapy is more effective than ever before at treating cancer, but has a price..
• Therapeutic choices for both cardiology and oncology have significant overlap
These are by far the two most common disease conditions in the developed world….

CARDIO TOXICITY

ANTHRACYCLINES
ANTHRACYCLINES
• Anthracyclines have been used as efficacious antineoplastic agents for many haemopoietic and solid cancers since they were first isolated from the pigment-producing Streptomyces peuctius early in the 1960s.
However,dose-dependent risk of cardiomyopathy and congestive heart failure has restricted their clinical utility.
ANTI TUMOR ACTIVITY
• ACTIVATION OF SIGNAL TRANSDUCTION PATHWAYS
• GENERATION OF REACTIVE OXYGEN INTERMEDIATES
• STIMULATION OF APOPTOSIS• INHIBITION OF TOPOISOMERASE II
CARDIO TOXICITY
Acute or sub acute-• abnormalities in vent. repolarisation
& electrocardio QT- interval changes• Supraventricular & ventricular
arrhythmias• Acute coronary syndromes• Pericarditis & / or myocarditis like
syndrome• Upto 2 weeks
CARDIO TOXICITY
• Chronic – early-<1 yr of chemotherapy late ->1 yr of chemotherapy• Typical sign- asymptomatic sys.
& or diast Lt. ventricular dysfunction
CARDIO TOXICITY
• Mechanism- Oxidative stress Iron overload/Calicum overload Anthracycline Metabolites- Doxorubicinol PAF Hypothesis Down regulation of ß receptors

CARDIO TOXICITY
• The occurrence of CHF is dose- and schedule-dependent.
• left ventricular dysfunction is more frequently observed in women, in patients with personal history of cardiac disease, and after mediastinal X-ray therapy .
• The risk of cardiotoxic adverse events increases when anthracycline chemotherapy is administered concurrently or sequentially before adjuvant therapy with trastuzumab.

How do we best detect cardiotoxicity by Echo?
Belham et al. Eur J Heart Failure. 2006: Oct 23 epub.
Sa = longitudinal (annular) systolic contraction, E = transmitral E wave velocity, A = transmitral A wave velocity, Ea = longitudinal (annular) early diastolic relaxation velocity. *P < 0.05 compared to baseline. **P < 0.01 compared to baseline. ***P < 0.001 compared to baseline. ****P < 0.0001 compared to baseline. #P < 0.05 compared to low dose.

Cardinale D et al. Circulation. 2006;114:2474-2481
CARDIO TOXICITY
• Dose reductions limit the incidence of early cardiac events but not that of delayed sequelae, possibly indicating that any dose level of antitumor drugs would prime the heart to damage from sequential stressors.
The risk of developing cardiotoxicity is mainly related to the total cumulative dose of doxorubicin (1% to 5% up to 550 mg/m2, 30% at 600 mg/m2, and 50% at 1g/m2 or higher) with individualvariation. The risk increases proportionally to the total accumulateddose in a nonlinear fashion, so that there probably is no safe dose of doxorubicin. It is increasingly recognized that abnormalities in non invasive studies can be found in greater frequency and at a lower cumulative dose than previously reported.

Difficulties in diagnosing “heart failure”
• Can be a wide range of presentations• Many of the symptoms of heart
failure overlap with other disease states such as COPD, Obesity, Nephrotic Syndrome, Drug induced Edema, Cirrhosis, Sleep Apnea, and Cancer
• How to effectively and efficiently differentiate between these entities?

• How to effectively and efficiently differentiate between these entities?
Detecting CardiotoxicitySummary of current methods
• The guidelines*at present suggest a baseline EF measurement and a repeat study at some time interval (keep in mind that more than 1/3 of patients with heart failure have a normal EF and their prognosis is similar to those with systolic dysfunction)
• Symptoms are the mainstay of the diagnosis of heart failure (and the utility of
that is in question) • No recommendation for biomarker
testing or preventive therapy

ANTHRA AND TRAZ
• Anthracyclines are the precipitating factor for trastuzumab-induced cardiotoxicity and, therefore, anthracyclines and trastuzumab should not be given synchronously
• Trastuzumab can usually be given safely following completion of adjuvant anthracycline based chemotherapy, and trastuzumab-associated cardiotoxicity is usually treatable and reversible
• Regular left-ventricular function monitoring before and during therapy is mandatory in all patients receiving adjuvant trastuzumab after anthracyclines
ANTHRA AND TRAZ
• In patients with advanced disease, the clinical benefit from trastuzumab needs to be balanced against cardiotoxicity
• Trastuzumab in combination with nonanthracycline chemotherapy does not seem to be associated with any increased risk of cardiotoxicity
• The optimal duration for adjuvant trastuzumab therapy suggested by current data is 1 year, although some data support as little as 9 weeks of trastuzumab; however, scheduling trastuzumab before initiating adjuvant anthracycline therapy remains experimental and might be risky because of the long half-life of trastuzumab
Bevacizumab
• Bevacizumab is also associated with hypertension and instances of thromboembolism, pulmonary hemorrhage, and pulmonary edema or gastrointestinal tract bleeding.
• Antiangiogenesis class of drugs can also harbor cardiovascular toxicity, as indicated by a reduction of LVEF that over the long term may result in CHF
