Background ¤  Conven'onal anthracyclines are the most widely used agents to treat breast cancer in the adjuvant se8ng, as well as in metasta'c disease. ¤  Doxorubicin-­‐ based regimens have demonstrated benefits in terms of ORR, TTP, and OS. ¤  Despite its excellent an'tumor ac'vity, however, conven'onal doxorubicin has a rela'vely low therapeu'c index, and its use is limited by acute side effects, as myelosuppression, alopecia, acute nausea and vomi'ng, stoma''s, cardiac events (LVD, myocardi's, arrhythmia) ¤  Cumula:ve cardiotoxicity is a major concern, leading to poten'ally fatal conges've heart failure. Azienda Sanitaria Firenze

Anthracycline-­‐induced cardiotoxicity ¤  Cardiotoxicity occurs when metabolic free radicals cause lipid peroxida:on. ¤  Ini'ally, damage to the heart is subclinical; however, con'nued treatment will lead to progressive myocyte damage. The resul'ng cumula've cardiac dysfunc'on may become evident during therapy or subsequently in months or years aMer the final doxorubicin dose. ¤  Several factors may poten'ally increase the pa'ent’s risk of developing anthracycline-­‐induced cardiotoxicity: higher cumula,ve anthracycline dose increased rate of drug administra,on advanced or very young age medias,nal radia,on female gender preexis,ng heart disease hypertension.

OS Cardiac CHF astatic breast carcinoma (MBC).
Toxicity (%) (months) METHODS.
Two hundred twenty-four patients with MBC and no prior therapy(N) for
of the liposome-encapsulated doxorubicin, TLC D-99 (Myocet, Elan Pharmaceuticals, Princeton, NJ), and conventional doxorubicin in first-line treatment of met-
metastatic disease were randomized to receive either TLC D-99 (75 mg/m2) or
doxorubicin (75 mg/m2) every 3 weeks, in the absence of disease progression or
unacceptable toxicity. The primary efficacy endpoint was response rate. Responses
were assessed using World Health Organization criteria and were required to be of
at least 6 weeks’ duration. The primary safety endpoint was cardiotoxicity. Cardiac
function was monitored by multiple-gated radionuclide cardioangiography scan,
and the left ventricular ejection fraction (LVEF) was scored at a central laboratory.
Patients were removed from study if LVEF declined 20 or more EF units from
baseline to a final value of greater than or equal to 50%, or by 10 or more units to
a final value of less than 50%, or onset of clinical congestive heart failure (CHF).
RESULTS. Median age was 54 years in both treatment groups. All relevant prog-

of Liposome-Encapsulated Doxorubicin and
Cyclophosphamide Compared With Conventional
Doxorubicin and Cyclophosphamide in a Randomized,
Multicenter Trial of Metastatic Breast Cancer
By Gerald Batist, Gopal Ramakrishnan, Chandra Sekhar Rao, Aruna Chandrasekharan, John Gutheil, Troy Guthrie,
Pankaj Shah, Ali Khojasteh, Madhavan Krishnan Nair, Karen Hoelzer, Katherine Tkaczuk, Youn Choi Park,
and Lily W. Lee for the Myocet Study Group
Purpose: To determine whether Myocet (liposomeencapsulated doxorubicin; The Liposome Company,
Elan Corporation, Princeton, NJ) in combination with
cyclophosphamide significantly reduces doxorubicin
2 cardiotoxicity while providing comparable antitumor
efficacy in first-line treatment of metastatic breast
cancer (MBC).
Patients and Methods: Two hundred ninety-seven
patients with MBC and no prior chemotherapy for metastatic disease were randomized to receive either 60
mg/m2 of Myocet (M) or conventional doxorubicin (A),
in combination with 600 mg/m2 of cyclophosphamide
(C), every 3 weeks until disease progression or unacceptable toxicity. Cardiotoxicity was defined by reductions in left-ventricular ejection fraction, assessed by
serial multigated radionuclide angiography scans, or congestive heart failure (CHF). Antitumor efficacy was assessed
by objective tumor response rates (World Health Organization criteria), time to progression, and survival.

OXORUBICIN IS recognized as one of the most
active drugs for breast cancer, but its clinical utility is
limited because of a cumulative dose-dependent cardiac
myopathy that can lead to potentially fatal congestive heart
Results: Six percent of MC patients versus 21% (including five cases of CHF) of AC patients developed
cardiotoxicity (P ! .0002). Median cumulative doxorubicin dose at onset was more than 2,220 mg/m2 for MC
versus 480 mg/m2 for AC (P ! .0001, hazard ratio,
5.04). MC patients also experienced less grade 4 neutropenia. Antitumor efficacy of MC versus AC was comparable: objective response rates, 43% versus 43%;
median time to progression, 5.1% versus 5.5 months;
median time to treatment failure, 4.6 versus 4.4
months; and median survival, 19 versus 16 months.
Conclusion: Myocet improves the therapeutic index
of doxorubicin by significantly reducing cardiotoxicity
and grade 4 neutropenia and provides comparable
antitumor efficacy, when used in combination with
cyclophosphamide as first-line therapy for MBC.

hazard ratio (HR) = 1.00; 95% confidence interval (CI) 0.82–1.22]. Subgroup results were consistent. Overall
risk of cardiotoxicity was significantly higher with doxorubicin than PLD (HR = 3.16; 95%CI 1.58–6.31;
P <0.001). Overall survival was similar (21 and 22 months for PLD and doxorubicin, respectively; HR = 0.94;

mucositis (23% versus 13%) were more often associated with PLD than doxorubicin.
Conclusions: In first-line therapy for MBC, PLD provides comparable efficacy to doxorubicin, with significantly reduced cardiotoxicity, myelosuppression, vomiting and alopecia.

Purpose
To determine whether the combination of pegylated liposomal doxorubicin (PLD) and docetaxel
significantly prolongs time to disease progression compared with docetaxel alone without an
increase in cardiac toxicity in women with advanced breast cancer who had experienced relapse
at least 1 year after prior adjuvant or neoadjuvant anthracycline therapy.
N. RR TTP (%) (months) Patients and Methods
Cardiac Toxicity (%) PPS (%) This international, phase III study randomly assigned 751 patients to receive either docetaxel 75
mg/m2 (n ! 373) or PLD 30 mg/m2 followed by docetaxel 60 mg/m2 every 21 days (n ! 378) and
continued until disease progression or prohibitive toxicity. The primary end point was time to
progression (TTP). Secondary end points were overall survival (OS), objective response rate (ORR),
cardiac toxicity, and safety.

Results
Treatment with PLD-docetaxel significantly improved median
ratio [HR] ! 0.65; 95% CI, 0.55 to 0.77; P ! .000001) and the ORR from 26% to 35% (P ! .0085).
OS was similar between the two groups (HR ! 1.02; 95% CI, 0.86 to 1.22). The incidence of grade
24 5 9.8 377 35 3 or 4 adverse events were similar (78% v 72%), although a higher incidence of hand-foot

Conclusion The PLD-docetaxel combination was more effective than docetaxel alone in women with
metastatic breast cancer who had experienced relapse at least 1 year after prior adjuvant
anthracycline therapy without an increase in cardiac toxicity, although mucocutaneous toxicity was
more common.

However, when trastuzumab is combined with anthracyclines there is an increased risk of cardiac toxicity. ¤  Cardiotoxicity limited the use of anthracyclines in HER2-­‐posi've breast cancer, and in consequence non-­‐anthracycline-­‐based regimens such as TCH were designed in order to avoid late-­‐toxici'es, especially in adjuvant se8ng . ¤  As anthracyclines showed a high level of ac'vity in this subgroup of pa'ents, other strategies were developed also to design regimens using less cardiotoxic anthracyclines such as epirubicin (a less cardiotoxic analog than doxorubicin) at limited doses or liposomal anthracyclines in combina'on with trastuzumab.

Among 12 500 women (mean age = 60 years, range = 22–99 years), 29.6% received anthracycline alone, 0.9%
received trastuzumab alone, 3.5% received anthracycline plus trastuzumab, 19.5% received other chemotherapy, and 46.5% received no chemotherapy. Anthracycline and trastuzumab recipients were younger, with fewer
comorbidities than recipients of other chemotherapy or none. Compared with no chemotherapy, the risk of HF/
CM was higher in patients treated with anthracycline alone (adjusted HR = 1.40, 95% CI = 1.11 to 1.76), although the

Conclusions
Anthracycline and trastuzumab were primarily used in younger, healthier women and associated with increased
HF/CM risk compared with no chemotherapy. This population-based observational study complements findings

Liposomal Anthracyclines in metasta:c sefng ¤  In pa'ents with metasta'c breast cancer, liposomal anthracyclines have proven to be as effec've and less toxic when compared face to face with conven'onal anthracyclines, allowing a longer period of treatment and a higher cumula've dose of the anthracyclines. ¤  The combined analysis of available data indicates an overall reduc'on in risk for both cardiotoxicity and clinical heart failure. ¤  The safety of liposomal anthracyclines endorsed its use in pa'ents with some cardiac risk factors.

Liposomal Anthracyclines in combina:on with Trastuzumab: ¤ 
In HER2-­‐posi've breast cancer, the addi'on of trastuzumab to chemotherapy significantly increased response rate, progression-­‐free survival, and overall survival. ¤ 
Ini'al studies demonstrated synergy when trastuzumab was combined with anthracyclines, but their excessive cardiac toxicity limited their use, and nonanthracycline therapeu'c strategies were therefore designed. ¤ 
Liposomal anthracyclines have proven to be effec've and safe when combined with trastuzumab both in advanced and early breast cancer. Of par'cular interest is the use of the combina'on of liposomal anthracyclines plus trastuzumab in pa'ents with early and HER2-­‐overexpressing breast cancer, as this is probably the subgroup that would benefit most from a treatment with anthracyclines. ¤ 
The poten'al clinical benefit of anthracyclines in this se8ng should be inves'gated in a clinical trial comparing a regimen with liposomal anthracyclines versus a nonanthracyclines combina'on. Azienda Sanitaria Firenze
