How do gene expression profiling results influence your recommendations for surveillance intensity in patients with early-stage melanoma?
Gene expression profiling (GEP) defines surveillance intensity for early-stage melanoma. Early-stage melanoma (i.e., stage I) would not typically be expected to metastasize or recur. Patients at high genomic risk of recurrence should be surveilled more closely, including self-skin exams in between r...
How do gene expression profiling results impact your decisions regarding adjuvant therapy in node-negative or borderline-risk melanoma patients?
Node-negative patients comprise a majority of bad outcomes from melanoma deaths. These are the patients that I worry about the most, and 90% or so of lymph node biopsies are negative. High-risk DecisionDx-Melanoma (DDx-M) scores allow for routine serial imaging despite a negative lymph node biopsy. ...
Do you get DEXA scans routinely before starting ADT for prostate cancer or endocrine therapy for breast cancer?
When initiating long-term ADT, I order a DEXA scan, check vitamin D level, ensure adequate dietary calcium intake, and discuss weight-bearing exercise/refer to PT when appropriate. I also continue check DEXAs every 2 years unless they otherwise meet criteria for a bone-modifying agent (mCRPC with bo...
Is there benefit to aggressively treating hemochromatosis in a patient who has already progressed to cirrhosis at the time of diagnosis?
The short answer is yes, there is a benefit to treating iron overload in a patient with hereditary hemochromatosis (HH) with cirrhosis. HH involves at least five mutations, most commonly in the HFE gene (common variants include C282Y and H63D), leading to hyperabsorption of iron and progressive accu...
For patients on immune checkpoint inhibitors presenting with chest pain, dyspnea, fatigue, and troponin elevation, would you recommend early initiation of high dose steroids for empiric treatment of ICI myocarditis while pursuing workup with coronary angiogram, echocardiogram, and/or cardiac MRI, or wait until alternative etiologies have been ruled out?
This question raises an important point that the clinical presentation of ICI-associated myocarditis often overlaps with other cardiovascular disorders, including acute coronary syndrome, chronic CAD, congestive heart failure, and other nonischemic cardiomyopathies. Therefore, prompt initiation of w...
Should all patients with a remote history of immunotherapy, chemotherapy and/or radiation therapy have a baseline TTE regardless of ASCVD risk?
The current ASCVD risk assessment calculators we have available do not contain cancer-specific parameters and thus are inadequate for accurate assessment of a cancer survivor's risk of developing CHF and ischemic heart disease. If patients have received mediastinal radiation therapy or high-dose ant...
Given recent studies investigating ICI myocarditis biomarkers such as Temra CD8+ cells, is there now a growing selection of clinical biomarkers, besides BNP and troponin, being measured routinely in ICI myocarditis cases?
Since novel biomarkers are not yet clinically available in most practice settings, these are not yet routinely being checked though they certainly merit further investigation for diagnosis of ICI myocarditis. Currently, recommended biomarkers include indicators of cardiac injury (troponin, BNP or NT...
When would you consider tapering glucocorticoids in a patient with ICI-associated myocarditis?
Once troponins start to decrease, I start the steroid taper and follow troponin levels. If they rise, I slow the taper. I also get serial ECGs, esp if there were arrhythmia manifestations of myocarditis. Don't forget to assess for the need for PJP prophylaxis with Bactrim or pentamidine and PPI sinc...
What is your surveillance approach for outpatient monitoring of ICI myocarditis?
Screening and surveillance strategies for outpatient monitoring of ICI myocarditis are not well-defined. The best surveillance approach would be based on clinical risk assessment, followed by biomarker and imaging data. The risk factors for ICI myocarditis remain to be clarified, but the most valida...
What would be your preferred anticoagulant for recurrent DVT/PE in a patient on hemodialysis with calciphylaxis and prior DOAC failure?
A truly complex case: recurrent DVT/PE in the setting of ongoing risk factors for both VTE (active calciphylaxis, prior DOAC failure, and obesity) and bleeding (ESRD on hemodialysis), each of which constrains a different anticoagulant option. Given the complexity and rarity of this case, recommendat...
