INTRODUZIONE
 Le antracicline, antibiotici glicosidici, rappresentano
una classe di agenti citotossici efficaci nel
trattamento di un ampio spettro di neoplasie tra cui
il carcinoma della mammella
 Il loro potenziale terapeutico è limitato dallo sviluppo
di cardiotossicità, che può indurre a scompenso
cardiaco irreversibile
 Ne consegue un aumento della morbilità e mortalità
dei
pazienti
sottoposti
a
tale
trattamento
chemioterapico
Lipshultz et al, 2005
DEFINIZIONE
 The cardiac review and evaluation committee supervising trastuzumab
clinical trials, which defined drug-associated cardiotoxicity as one or
more of the following:
– 1) cardiomyopathy in terms of a reduction in left ventricular
ejection fraction (LVEF), either global or more severe in the
septum;
–
2) symptoms associated with heart failure (HF);
– 3) signs associated with HF, such as S3 gallop, tachycardia, or
both;
– 4) reduction in LVEF from baseline that is in the range of less
than or equal to 5% to less than 55% with accompanying signs or
symptoms of HF, or a reduction in LVEF in the range of equal to
or greater than 10% to less than 55%, without accompanying signs
or symptoms.
 This definition does not include subclinical cardiovascular damage that
may occur early in response to some chemotherapeutic agents.
 Thus, to date, an ideal definition is lacking.
INCIDENZA
And the estimated risk of anthracycline-induced
clinical heart failure increased with time to 5.5% at
20 years after the start of anthracycline therapy.
In patients treated with a cumulative anthracycline
dose of 300mg/m² or more the risk was even higher,
almost 10%.
The incidence of anthracycline-induced asymptomatic
cardiac dysfunction has been reported to be more
than 57% at a median of 6.4 years after treatment.

POSSIBILI FUTURI MARKERS
 The diagnostic and prognostic value of other biomarkers used to
monitor cardiovascular damage, such as myeloperoxidase should
also be validated for clinical use in cardio-oncology.
 Genomics, proteomics, and/or recently identifi ed oligoclonal Bcell repertoires may provide us with genomic profiLes and
serological biomarkers for assessment of cardiotoxicity in the
foreseeablE future.

DERIVATI LIPOSOMIALI
DELLE ANTRACICCLINE
 Liposomal preparations of athracyclines also show
promise in reduction of cardiac toxicity
 Liposomes are preferentially taken up by tissues
enriched in phagocytic reticuloendothelial cells
 In a retrospective analysis of 8 phase I and II
clinical trials, there was not a clinically significant
decrease in EF in 41 patients treated with 500
mg/m2
 In many trials, it appears to be as effective as
standard doxorubicin

DEXRAZOXANE
 Dexrazoxane is an oral iron chelator
 It prevents the formation of the semiquinone-iron which leads to
reactive oxygen production
 It has been tested in multiple clinical trials and has been shown to
reduce cardiac toxicity
 In 2 randomized controlled trials performed in metastatic breast
cancer, 289 patients being treated with FDC and 249 were FDC +
dexrazoxane.
 Symptomatic CHF developed in 8% of the placebo group versus 1% of
the dexrazoxane group
 Similar results were seen in other trials using FEC for metastatic
breast cancer and epirubicin for sarcoma
RACCOMANDAZIONI ASCO
 Not recommended for initial therapy
 Breast patients receiving more than 300 mg/m2 of
doxorubicin
 Consideration in patients with other malignancies
receiving more than 300 mg/m2 of doxorubicin
AGENTI ANTIOSSIDANTI

POSSIBILI FUTURI FARMACI
CARDIOPROTETTIVI (2)
 Lipid-lowering agents have been indicated as protective agents
against anthracycline-mediated cardiotoxicity ( 92 ), and, in
particular, statins seem to have a chemopreventive and direct
antitumor effect ( 93 , 94 ).
 Whether statins may have protective or harmful effects on
cancer risk is still a matter of debate, but the most recent
reviews of the literature suggest that these drugs do not have
short-term negative consequences on cancer risk ( 95 ).
 Moreover, they can have an antithrombotic effect ( 96 ) that
could lower the risk of thrombosis induced by anticancer
treatment.
APPROCCIO PREVENTIVO E
TERAPEUTICO
CONCLUSIONI
 To date, no guidelines have been developed specifically for the
definition, detection, or therapy of cardiotoxicity from
antineoplastic therapy, so it is imperative that these guidelines
be defined.
 Meanwhile, cancer patients with cardiovascular diseases should
be treated based on the guidelines published by the American
College of Cardiology and American Heart Association ( www .
acc . org / quality and science / clinical / statements . htm ).
 We suggest the need to develop a clinical risk-score of an
integrated multidisciplinary approach to treat with lyposomal
anthracycline’s derivates and standard therapy of heart failure
all patients in medium-high risk class.
