Recommendations for the management of cardiovascular risk in patients with chronic myeloid leukemia on tyrosine kinase inhibitors: risk assessment, stratification, treatment and monitoring

ABSTRACT This manuscript summarizes the results of the consensus meeting composed of hematologists and cardiologists to establish recommendations for the prevention and follow-up of cardiovascular (CV) risk in patients with chronic myeloid leukemia (CML) treated with BCR-ABL tyrosine kinase inhibitors (TKIs) from the point of view of clinical practice and from the perspective of hematology consultation.In the first medical appointment, the CV risk factors should be identified to perform the baseline risk stratification, based on the Brazilian Guideline of Dyslipidemia and Atherosclerosis Prevention Update (risk levels: very high, high, intermediate and low).Once stratified, the treatment of the CV risk factors should be administered. If the patient presents risk factors, such as hypertension, diabetes, renal disease, smoking and hypercholesterolemia, the evaluation and initial treatment may be done by the hematologist, being an option the request for evaluation by a specialist. If the patient has a history of previous CV disease, we recommend referral to a specialist. As the CV risk score is dynamic and the control of risk factors can reduce the patient risk, this expert consensus recommends that the re-evaluation of the CV risk after the baseline should be performed at 3 months, 6 months and 12 months. After this period, it should be done annually and, for specific patients, at the clinician's discretion.The evaluation of the baseline CV risk and the safe administration of a TKI allow the patient to benefit from the maximum treatment, avoiding unwanted effects.

Inclusion of molecular monitoring (BCR-ABL1) in the treatment of chronic myeloid leukemia in the Brazilian Public Health System (SUS): an urgent need for treatment management

ABSTRACT Introduction: Chronic Myeloid Leukemia (CML) is a myeloproliferative disease that affects mainly adults between 50 and 55 years. In Brazil, information from the Sistema Único de Saúde (SUS) Outpatient Information System indicates that 12,531 patients had the Autorização de Procedimento Ambulatorial (APAC) approved for the CML treatment in 2017. Disease monitoring through molecular response evaluation is critical to the care of CML patients. The quantitative PCR test (real-time polymerase chain reaction) provides adequate evaluation parameters that allow the health professional to intervene at the right moments in order to reduce the chance of progression of the disease, providing the best outcome to the patient, including the possibility of treatment discontinuation for eligible patients. Although the test is included in the Clinical Protocol and Therapeutic Guidelines (PCDT) of CML, it is not possible to monitor the molecular response within SUS since there is no reimbursement for this test. Objective: Obtain expert recommendations on the importance, financing, and reimbursement of molecular monitoring in SUS. Methods: Six CML experts with different perspectives participated in the panel. The discussion was based in the main publications about the quantitative PCR test in CML monitoring. Results: Experts' recommendations: Molecular monitoring should be part of the integral treatment of patients with CML to reduce the chances of disease progression and costs to the health system; The government should put into practice what is provided in the PCDT of Chronic Myeloid Leukemia in Brazil: performing the monitoring of the molecular response via quantitative PCR; The government should create a code with adequate nomenclature and reimbursement value in SIGTAP, so that the test is carried out and covered by the public health network, as it is contained in the PCDT of the disease and the existing APAC does not cover the operational costs for its performance; Patients with chronic phase CML should perform a quantitative PCR every 3 months and, after reaching the MMR, should perform the examination every 6 months, as recommended by international guidelines; Patients should be monitored in reference laboratories that are standardized according to the international scale; The laboratories that are within the reference public centers could absorb all the test demand in Brazil, and other centers could be qualified through an ABHH accreditation; Adequate molecular monitoring may allow some patients to stop taking drugs and selffinancing the molecular test for all SUS patients Conclusion: A solution for the molecular test (BCR-ABL1) funding is urgent to ensure the monitoring of CML patients in SUS. The savings that might be generated with patients that stop taking the medication when adequately monitored may finance the test.

How to manage lymphoid malignancies during novel 2019 coronavirus (CoVid-19) outbreak: a Brazilian task force recommendation

ABSTRACT: The novel Coronavirus (CoVid-19) outbreak is now consider a world pandemic, affecting more than 1,300,000 people worldwide. Cancer patients are in risk for severe disease, including a higher risk of intensive care unit (ICU) admission, need for invasive ventilation or death. Management of patients with lymphoid malignancies can be challenging during the outbreak, due to need of multiple hospital visits and admissions, immunosuppression and need for chemotherapy, radiotherapy and stem cell transplantation. In this article, we will focus on the practical management of patients with lymphoid malignancies during the COVID-19 pandemic, focusing on minimizing the risk for patients.

Cardiovascular Manifestations of Erdheim-Chester's Disease: A Case Series / Manifestações Cardiovasculares da Doença de Erdheim-Chester: Uma série de Casos

Abstract Erdheim-Chester Disease is a rare entity, classified as an inflammatory myeloid neoplasm, with an unknown incidence, occurring preferentially in men after 50 years of age. Classically, it has a multisystemic presentation, with the skeletal system being the most frequently affected (90% of the patients), followed by genitourinary involvement in 60% of cases and central nervous system in the pituitary and diabetes insipidus in 25% of the cases. Cardiovascular manifestations are present in more than half of the patients, with aortic infiltration and atrial pseudotumor being the most common forms.

Resumo A doença de Erdheim-Chester é uma entidade rara classificada como neoplasia mielóide inflamatória, com incidência desconhecida que ocorre preferencialmente em homens após os 50 anos de idade. Classicamente apresenta-se de forma multissistêmica, sendo sistema esquelético o mais frequentemente comprometido (90% dos pacientes), seguido do sistema geniturinário em 60% dos casos e sistema nervoso central em hipófise e diabetes insipidus em 25% dos casos. As manifestações cardiovasculares estão presentes em mais da metade dos pacientes, sendo a infiltração da aorta e o pseudotumor atrial as formas mais encontradas.
