Myeloproliferative Neoplasm Symptom Assessment Form - Total Symptom Score (MPN-SAF TSS) questionnaire: translation, cultural adaptation and validation to Brazilian Portuguese

ABSTRACT Introduction: Constitutional symptoms and thrombohemorrhagic events are common in patients with myeloproliferative neoplasms (MPNs). Hence, the treatment's primary goal is to control symptoms and improve the quality of life (QoL). In order to assess response to therapy, symptom burden, and QoL among patients with MPN, the "Myeloproliferative Neoplasm Symptom Assessment Form - Total Symptom Score (MPN-SAF TSS)" questionnaire was developed in the USA in 2012. Herein, we translated and validated the MPN-SAF TSS questionnaire to Brazilian Portuguese. Methods: The ten-item questionnaire was translated from the English language and its psychometric properties (reliability, convergent and construct validities) were evaluated in 101 MPN patients. Results: There were 41 patients with essential thrombocythemia, 39 with myelofibrosis and 21 with polycythemia vera. The median age of all patients at diagnosis was 68 years and 59% were female. The Cronbach's alpha coefficient for the overall questionnaire was 0.78, ranging from 0.73 to 0.79, if each item was deleted. Validity analyses showed that the strongest item-item correlation were between early satiety and abdominal discomfort. Strong correlations were also found between physician and patient perceptions of itching (r = 0.81) and fatigue (r = 0.70). The Pearson coefficient correlation between the MPN-SAF TSS global score and the EORTC QLQ-C30 functional scales ranged from 0.51 to 0.64. The exploratory factor analysis showed that seven of the ten symptoms loaded into one single factor. Conclusion: The Brazilian Portuguese version of the MPN-SAF-TSS showed good psychometric properties and can be an available tool to assess symptom burden in this group of patients.

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.

Fertility in female survivors of Hodgkin's lymphoma

Currently, Hodgkin's lymphoma is one of the most curable types of cancer. Patients are often young and so the long-term morbidities of treatment have become of increasing concern. Among these, infertility is one of the most challenging consequences for patients in reproductive age. Premature ovarian failure in premenopausal women is a serious long-term sequel of the toxicity of chemotherapy. The main consequence of this syndrome is infertility, but women also present other symptoms related to estrogen deprivation. Different rates of impaired gonadal function are reported, depending on the patient's age, stage of disease, dose and intensity of chemotherapy and the use of radiation therapy. The most established strategy in female infertility is cryopreservation of embryos after in vitro fertilization. Additionally, the use of oral contraceptives or gonadotropinreleasing hormone analogs (GnRH-a) during treatment is under study. This review will provide a general overview of the main studies conducted to evaluate the infertility rate among female Hodgkin's lymphoma survivors and risk factors associated to treatment, different end-point definitions for evaluating fertility and also a brief description of the available strategies for fertility preservation.

Follicular lymphoma: treatment and prognostic factors

Follicular lymphoma is the second most frequent non-Hodgkin lymphoma accounting for about 10-20 percent of all lymphomas in western countries. The median age at diagnosis is 60 years old. The clinical presentation is usually characterized by asymptomatic peripheral adenopathy in cervical, axillary, inguinal and femoral regions. Treatment options for patients with naïve or recurrent follicular lymphoma are still controversial, ranging from a "watch and wait" policy to hematopoietic stem cell transplantation. More recently, the availability of rituximab has substantially changed follicular lymphoma therapeutic approaches to such an extent that R-Chemo is now the standard induction first-line treatment. This review provides a general overview of the state of the art in the management of follicular lymphoma and also, a brief description regarding the current prognostic tools available for treatment decisions.

Changing patterns of AIDS: impact on the indications and diagnostic yield of bone marrow biopsies

After the advent of HAART, the clinical course of HIV infection has dramatically improved. Therefore, it seems appropriate to reevaluate the performance of bone marrow biopsy (BMB) as a diagnostic tool. The aim of the present study was to compare the reasons for performing a BMB and its diagnostic yield in HIV-patients before and after HAART. A total of 165 BMB specimens obtained from HIV-infected patients receiving care at the Hospital of Universidade Federal do Rio de Janeiro in two different periods (1986-1994 and 1999-2004) were analysed. The main reason for BMB examination in the first period was fever (88 percent), which decreased in the second period (57 percent, p < 0.0001), when cytopenia (51 percent) was the leading reason for BMB, whereas in the first period it accounted for only 30 percent (p = 0.008). A definitive diagnosis (infection, granulomas or lymphomas) was obtained in 28 percent of patients in the first period and in 19 percent during the second period (p = 0.20). The diagnosis turned out as infections decreased from 16 percent in period 1 to 2 percent in period 2 (p = 0.003). Despite the the limitations in the evaluation of fever, the use of BMB must be considered on an individual basis, whenever less invasive alternatives have been exhausted, and should be complemented by a bone marrow aspiration for microbiological studies.

Advanced Hodgkin's lymphoma: results in 216 patients treated with ABVD in Brazil / Linfoma de Hodgkin em estádio avançado: resultados do tratamento em 216 pacientes tratados com ABVD no Brasil

The outcome of Hodgkin's lymphoma (HL) has markedly improved over the last few decades, placing HL among the human cancers with highest cure rates. However, data about treatment outcomes in developing countries are scarce. From 1996 to 2005, 370 consecutive patients with HL treated in three public institutions in Rio de Janeiro were identified. A total of 216 patients who presented with advanced stage (IIB-IV) HL were selected for the present analysis. Patients with advanced disease were treated with ABVD, complemented or not by radiation therapy. The median follow-up time of survivors was 6.3 years (1-11.8). Fifteen patients died during first-line treatment. The complete remission rate was 80 percent. The 5-year progression-free survival (PFS) and the 5-year overall survival (OS) probabilities were 69 percent and 83 percent, respectively. The 5-year PFS in low-risk and high-risk patients were 81 percent and 62 percent (p=0.003), respectively. The 5-year OS in low-risk and high-risk International Prognostic Score patients were 89 percent and 78 percent (p=0.02), respectively. The present study provides a representative estimate of current treatment results for advanced HL in public institutions in an urban area in Brazil. It is clear that full treatment can be given to most patients, although those with very low socio-economic status might require special attention and support. Since Brazil is a large country, with substantial interregional heterogeneity, a nationwide registry of HL patients is currently being implemented.

Os resultados do tratamento do linfoma de Hodgkin (LH) melhoraram substancialmente ao longo das últimas décadas e tornaram o LH uma das neoplasias humanas com maior chance de cura. Entretanto, os dados sobre tratamento em países em desenvolvimento são escassos. Entre 1996 e 2005, 370 pacientes consecutivos com LH tratados em três instituições públicas no Rio de Janeiro foram identificados. Destes, 216 em estádio avançado (IIB-IV) foram selecionados para esta análise. Os pacientes foram tratados com o protocolo ABVD (doxorrubicina, bleomicina, vinblastina e dacarbazina). A mediana do tempo de seguimento dos sobreviventes foi de 6,3 anos (1-11,8). Quinze pacientes morreram durante o tratamento de primeira linha. A probabilidade de sobrevida livre de progressão (SLP) em cinco anos e a probabilidade de sobrevida global (SG) em cinco anos foram de 69 por cento e 83 por cento, respectivamente. A SLP nos grupos de baixo risco e de alto risco, de acordo com o "International Prognostic Score", foi de 81 por cento e 62 por cento (p=0,003), respectivamente. A SG em cinco anos nos grupos de baixo risco e de alto risco foi de 89 por cento e 78 por cento (p=0,02), respectivamente. O presente estudo apresenta uma estimativa representativa dos resultados atuais do tratamento do LH avançado em instituições públicas no Brasil. Fica claro que o tratamento completo pode ser oferecido à grande maioria dos pacientes, embora aqueles com baixo status socioeconômico possam exigir atenção especial. Em vista das dimensões continentais do Brasil, com substancial heterogeneidade interregional, um registro nacional de pacientes com LH está sendo implementado.
