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.

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.

Indeterminate cell histiocytosis successfully treated with phototherapy.

First described in 1985, intermediate cell histiocytosis is a rare disorder of the cutaneous dendritic cell group with a varied clinical presentation and evolution. The pathologic substrate is constituted by the proliferation of indeterminate cells (ICs) that are immunophenotypically characterized by the positivity of CD1a, CD68, and faint/focal S100, plus the negativity for CD207 (langerin). The authors present the case of a healthy elderly woman who presented generalized dome-shaped reddish cutaneous nodules over her trunk, neck, face, and extremities over a period of 18 months. A laboratory and imaging work-up ruled out internal involvement. The skin biopsy was consistent with IC histiocytosis. The patient was treated with narrowband ultraviolet B phototherapy, which resulted in an excellent short-term outcome.

Diffuse large B-cell lymphoma presenting in the leukemic phase.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma comprising a heterogeneous group of disorders with variable histological and clinical behavior. Although other lymphomas may present in the leukemic phase more frequently, this appearance is unusually observed among DLBCL cases. Diagnosing lymphoma is not always easy, and the patient's clinical status quite often may hamper invasive procedures for diagnosis pushing the clinician to look for alternatives to reach the nearest possible accurate diagnosis. The authors report the case of a middle-aged man who presented the history of malaise, weight loss, and low-grade fever. The peripheral blood count showed leukocytosis with the presence of blasts and thrombocytopenia. The cytological morphology and immunophenotyping of the peripheral blood and bone marrow aspirate, as well as the bone marrow biopsy accompanied by a thorough immunohistochemical analysis, rendered the diagnosis of DLBCL in the leukemic phase. The patient was prescribed R-CHOP with a favorable outcome. Intra-abdominal lymph node biopsy was avoided because of the patient's critical medical condition. The authors highlight this rare form of presentation of DLBCL as well as the combination of peripheral blood, bone marrow aspirate, and bone marrow biopsy for reaching the diagnosis in cases were a lymph node sample is unavailable for the diagnostic work-up.

Hypertensive crisis: clinical-epidemiological profile.

Hypertensive crisis (HC) stands out as one type of acute elevation in blood pressure (BP) and can manifest as hypertensive emergency (HE-with target-organ damage (TOD)) or hypertensive urgency (HU-without TOD), usually accompanied by levels of diastolic BP ≥120 mmHg. The aim of this study was to characterize the clinical-epidemiological profile of HC over the course of 1 year in a university reference hospital and perform a review of the literature. The study was a cross-sectional study, conducted over a period of 1 year (2006) in 362 patients who presented for treatment at the emergency hospital with HC, as described above. Among all patients examined, 231 individuals met the criteria for HE and 131 met the criteria for HU. Patients with HE were older (P<0.001) and more sedentary (P=0.026) than those with HU. Furthermore, fewer HE patients than HU patients had previously undergone antihypertensive treatment (P=0.006). The groups did not differ regarding BP levels, gender, smoking or body mass index. Dyspnea (41.1%), thoracic pain (37.2%) and neurological deficit (27.2%) were common signs/symptoms in those with HE. Meanwhile, in the group with HU, we most frequently found headache (42.0%), thoracic pain (41.2%) and dyspnea (34.3%). Among the forms of HE, we most frequently observed acute lung edema (30.7%), myocardial infarction/unstable angina (25.1%), and ischemic (22.9%) and hemorrhagic (14.8%) stroke. HC is a clinical entity associated with high morbidity in the emergency room. Individuals with HE are older and sedentary and have lower rates of antihypertensive treatment. Adequate control of BP should be pursued as a way to avoid this severe complication of hypertension.
