International consensus statement on the management of cardiovascular risk of Bruton's tyrosine kinase inhibitors in CLL.

Bruton's tyrosine kinase inhibitors (BTKis) have altered the treatment landscape for chronic lymphocytic leukemia (CLL) by offering effective and well-tolerated therapeutic options. However, since the approval of ibrutinib, concern has risen regarding the risk of cardiovascular (CV) adverse events, including atrial fibrillation (AF), hypertension, and heart failure. Newer BTKis appear to have lower CV risks, but data are limited. It is important to understand the risks posed by BTKis and how those risks interact with individual patients, and we convened a panel of physicians with expertise in CLL and CV toxicities in oncology to develop evidence-based consensus recommendations for community hematologists and oncologists. Care providers should thoroughly assess a patient's CV risk level before treatment initiation, including established CV diseases and risk factors, and perform investigations dependent on preexisting diseases and risk factors, including an electrocardiogram (ECG). For patients with high CV risk, BTKi treatment is often appropriate in consultation with a multidisciplinary team (MDT), and more selective BTKis, including acalabrutinib and zanubrutinib, are preferred. BTKi treatment should generally be avoided in patients with a history of heart failure. Ibrutinib should be avoided in patients with a history of ventricular arrhythmias, but the risk of newer drugs is not yet known. Finally, an MDT is crucial to help manage emerging toxicities with the goal of maintaining BTKi therapy, if possible. Optimizing heart failure, arrhythmia, and hypertension control will likely improve tolerance and maintenance of BTKi therapy. However, additional studies are needed to identify the most optimal strategy for these drugs.

Cáncer de mama triple negativo, abortos a repetición e isquemia digital grave / Triple negative breast cancer, repeated abortions and severe digital ischemia

Resumen El presente caso corresponde a una mujer con antecedentes de tres abortos de menos de 10 semanas y cáncer de mama, que desarrolló isquemia digital grave luego del segundo ciclo de capecitabina. Se determinó la presencia de anticuerpos antifosfolipídicos positivos. Dado que las pacientes con síndrome antifosfolipídico obstétrico tienen incremento del riesgo de desarrollar neoplasia y que la isquemia digital grave puede ser la forma de presentación del síndrome antifosfolipídico en los pacientes con cáncer, se presenta el caso para remarcar el beneficio de pesquisar y realizar un diagnóstico temprano de estas características de la enfermedad.

Abstract The present case corresponds to a woman with history of three miscarrieges less than10 weeks and breast cancer, who develops severe digital ischemia after the second cycle of capecitabine. Positive antiphospholipid antibodies were determined. Patients with obstetric antiphospholipid syndrome have an increased risk of developing cancer, and severe digital ischemia could be an unusual form of presentation of the antiphospholipid syndrome in patients with cancer. This case is presented to highlight the benefit of researching and making an early diagnosis of these characteristics of the disease.
