How do you approach the re-challenge with trastuzumab in metastatic HER2+ patients who develop cardiomyopathy on trastuzumab/pertuzumab with subsequent improvement with discontinuation?
First, I send all my patients in this situation to the cardiologist. Second, I will re-start the treatment with close cardiology follow-up. Whether to re-load or not is an open question. I personally do not re-load, but I don’t think is wrong to re-load.
Would you discontinue dabrafenib/trametinib in a patient with BRAF mutant metastatic lung cancer if you see mild cardiomyopathy which could be related to the drugs?
This is a good question and a clinical scenario that I just recently ran into. The main question relates to the degree of LVEF change and whether the patient is symptomatic or not. It is not that uncommon overall. In the phase 2 trial of dabrafenib and trametinib that led to approval of this regimen...
What frontline treatment would you offer a patient with AITL who is not a candidate for an anthracycline due to baseline cardiomyopathy?
I would probably offer this patient CEOP. No data to back this up, however. Incorporation of etoposide in addition to CHOP confers a progression-free survival advantage in younger patients with PTCL, so it's reasonable to assume the etoposide would have activity.
Do you continue hydroxychloroquine in lupus patients who develop cardiomyopathy?
The short answer is yes, in that most lupus patients with cardiomyopathy do not have hydroxychloroquine drug induced cardiac injury. That is to say most of these patients either have ischemic cardiomyopathy or non-drug NICM. With that said, antimalarials can produce adverse effects both on the cardi...
What is the utility and recommendation for adding troponin and/or BNP to echocardiograms to screen for cardiac dysfunction In breast cancer patients receiving anthracycline based regimens?
For a healthy woman who received a total cumulative dose of 240 mg/m2 of doxorubicin, nothing more than a baseline echocardiogram is needed. JCO put out a clinical practice guideline in 2017 (Armenian et al., PMID 27918725) that covers the prevention and monitoring of cardiac dysfunction in survivor...
How do you balance short-course ADT in unfavorable intermediate risk prostate cancer patients with cardiac comorbidities?
One paper that addresses the topic was published in the Red Journal in 2016 (Rose et al., PMID 27788950). This retrospective analysis attempted to answer the question of which patients would derive disease-specific mortality benefit from the addition of ADT. Patients included in this analysis were f...
Is it safe to use statins in IIM patients if HMGCR antibodies are negative?
Absolutely, yes. Statins are a very important drug for patients with cardiovascular disease and should be given to most patients with myositis except patients with known immune-mediated statin myopathy or HMGCR Positive antibody. I would monitor CK levels before and 3 and 6 months post statin, as we...
Would you modify your initial treatment for a patient with de novo metastatic HR- HER2+ breast CA who has cardiomyopathy at baseline (EF < 35)?
Fortunately, the incidence of cardiotoxicity with the combination of a taxane, trastuzumab, and pertuzumab is very low, and thus I would be comfortable starting with this treatment (preferably with weekly paclitaxel) and monitoring her with periodic echocardiograms (every 4-6 cycles, in the absence ...
When is it necessary to monitor the QTc interval in patients on hydroxychloroquine?
The answer to this question is not straightforward mainly because there are limited data in this area. Hydroxychloroquine and Chloroquine directly affect cardiac repolarization and are associated with QT prolongation. Given this, there is an argument for getting a baseline ECG for patients initiatin...
For a patient with cardiac sarcoma, is there a minimum ejection fraction to proceed with adjuvant radiation therapy?
Adjuvant radiation therapy is often indicated for cardiac sarcoma because tumor resections are often incomplete or done with close margins. However, cardiotoxicity is a major issue, especially since patients will often receive doxorubicin-based chemotherapy, which has inherent cardiotoxicity. That b...
