Brief Summary:

Early identification of patients at risk for cardiotoxicity represent a primary goal for cardiologist and oncologist

From all adjuvant trials echocardiography is ideal for evaluating Left Ventricular function though its operator dependent. The use of other technique such as endomyocardial biopsy, is troublesome in clinical practice

Cardiac magnetic resonance imaging (MRI) have greater reproducibility in evaluating left ventricular ejection fraction (LVEF). This technique provides morphological, functional, perfusion, and viability information in one assessment. It is expensive and time consuming but id the diagnostic method of choice for patients with technically limited images from ECG and in patients with discordant information that is clinically significant from prior tests

Condition or disease Intervention/treatment
Breast Cancer Drug: Herceptin

Detailed Description:

Current standard of care for patients while on adjuvant trastuzumab is baseline ECHO are as follows:

Patients on one of the above medications should undergo regular monitoring of the heart function during treatment as the following:

  1. Baseline evaluation of LVEF prior inhibitor of therapy
  2. Serial assessment of LVEF using the same modality.

There is no clear international guidelines on the frequency and method of LVEF assessment.

Cardiac function is usually measured by using (ECHO) echo cardiography and multiple-gated acquisition (MUGA) The patient should be assessed with the same techniques during treatment to avoid stressing the myocardium by the use of exercise or ionotropic agent, before measuring LVEF to prevent earlier evidence of cardiotoxicity. Changes in the early atrial (E/A) filling ratio reflect ventricular compliance and may predict diastolic dysfunction and so decline in LVEF.

Diastolic dysfunction seems to be predictive of cardiac morbidity and mortality.

Trials with adjuvant trastuzumab use the rules for stopping cardiotoxic agents. They identified subset of high risk patients by one or two of the following three criteria:

  1. A decline with 10% or more in absolute LVEF from a normal base line to 50% or less
  2. a high cumulative dose of Doxorubicin ( > 450 mg/m2 ) and / or;
  3. abnormal baseline LVEF < 50% Patients who stopped taking doxorubicin after an LVEF decline were less likely to develop congestive heart failure (CHF) than those who did not.

Echocardiography is used regularly to monitor LVEF and is more widely available. The MUGA, in addition it does not expose patients to ionizing radiation but it is operator-dependent but training and use of automation may overcome the variation .

Group/Cohort Intervention/treatment
The study will be carried in prospective manner enrolling all patients diagnosed with breast cancer and over expressed human epidermal growth factor receptor 2 (HER2) and they are requiring Trastuzumab Neu adjuvant/ adjuvant /metastatic therapy as per standard care.
Drug: Herceptin

Herceptin will be administered in different way per each setting as follow::total herceptin cycles are 18.

Neu Adjuvant : chemo+herceptin, Surgery (hold herceptin) , Resume herceptin for 1 year period Adjuvant : Surgery, chemo+herceptin for 1 year period Metastatic : chemo+herceptin until progression.

Primary Outcome Measures :
  1. Estimate the incidence /of Herceptin induced heart failure in our population [ Time Frame: 3 years ]

    To evaluate the reversibility of damage in patients on long term follow- up for a period of up to three years.

    To identify the applicability of troponin / cardiac natriuretic peptides (CNPS) as bio marker that can predict the occurrence of clinically significant left ventricular dysfunction.

    To evaluate the role of MRI in identifying patient at risk to develop cardio toxicity.

    Determine the frequency of elevated Troponin and B-type natriuretic peptide (BNP) in patient receiving adjuvant herceptin.

Secondary Outcome Measures :
  1. Determine the incremental diagnostic value of Trop and BNP in predicting incidence of Hem CMP. [ Time Frame: 3 years ]

    Determine the incremental diagnostic value of Trop and BNP in predicting incidence of Hem cardiac marker (CMP).

    Determine the relation between prior myocardial scaling and incidence of herceptin induced cardiac marker (CMP).

    Determine the correlation between myocardial edema, BNP and heart failure incidence of CMP
