RESUMO

Classic Hodgkin lymphoma (CHL), which accounts for 90-95% of all cases of Hodgkin lymphoma, is the most frequent cancer in adolescents and the most frequent lymphoma in adolescents and young adults. Despite progressive improvements over past decades and the general sensitivity of CHL to frontline chemotherapy, approximately 10-15% of patients have refractory disease that either does not respond to such therapy or progresses after an initial partial response. In patients with refractory or relapsed disease, standard treatment until recently consisted mainly of salvage chemotherapy, in many cases followed by high-dose chemotherapy and autologous stem-cell transplantation. However, improved understanding of the pathobiology of CHL, coupled with the introduction of novel agents, has markedly changed the treatment landscape in the past decade. Although refractory or relapsed CHL continues to be challenging, the therapeutic landscape is undergoing profound changes brought about by novel agents, particularly brentuximab vedotin and immunotherapy. In this review, we discuss the most salient treatment options for adult patients with refractory or relapsed CHL, with a special focus on the Brazilian healthcare setting, which is constrained by inherent characteristics of this system. In the attempt to balance efficacy, safety and tolerability, practicing physicians must rely on clinical trials and on results from real-world studies, and use their own point of view and experience, as well as patient characteristics and previous therapy, to make treatment decisions for refractory or relapsed CHL.

RESUMO

Castleman's disease (CD) is a rare and heterogeneous lymphoproliferative disorder, with limited available clinical information in Brazil. A retrospective study was carried out through information contained in the medical records of 51 patients, between July 1999 and June 2020. Seven patients were excluded, and 44 were analyzed in total. The average age of unicentric CD (UCD) patients was 35 years old and of multicentric CD (MCD) patients was 49 years old (p = 0.013). Regarding gender, there was a predominance of females among patients with UCD (68.4%) and males in patients with MCD (57.9%) (p = 0.103). The most common site of involvement in UCD was the cervical region (36.8%). A total of 73.7% of patients with UCD and 68.4% of patients with MCD presented the histological form hialyne-vascular (HV) (p = 0.499). Most patients with laboratory abnormalities had MCD. A total of 78% of the patients were asymptomatic, with the majority of symptomatic patients with MCD (p = 0.042). Only two of the 27 patients evaluated for the presence of human immunodeficiency virus (HIV) had positive serology. HHV-8 was evaluated in 14 cases, being positive in two. Of the patients with UCD, 94.7% underwent excisional biopsy, against only 41.2% of patients with MCD (p = 0.01). The mean follow-up was 61 months. We observed similarities in the clinical profile between patients in our study and patients described in the literature, such as gender, mean age, B symptoms, visceromegaly, fluid accumulation, and treatment. Unlike the literature, the cervical region was the most affected site, besides the greater association of the HV histological subtype among patients with MCD.

RESUMO

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.

RESUMO

Eosinophilic dermatosis of hematological malignancy is a paraneoplastic skin eruption associated with chronic lymphocytic leukemia and other B-cell malignancies. It clinically resembles an insect bite reaction and it can precede the symptoms of the hematological malignancy or be related to a more aggressive course. Different treatments have been proposed, but partial response and recurrence are frequent. Herein, we describe a case of eosinophilic dermatosis associated with mantle cell lymphoma with remission after lenalidomide therapy.

RESUMO

PURPOSE: It has become crucial to translate scientific findings and to find ways by which to mobilize local resources to improve the quality and accessibility of cancer care in developing countries. This study seeks to provide insight into challenge through examining differences in clinician documentation of patients with cancer treated at a Brazilian Public University Hospital. METHODS: ASCO Quality Oncology Practice Initiative (QOPI) measures were used to examine the care provided in the departments of breast, colorectal, lymphoma, gynecology, and lung cancers. For this study, data from a representative sample of patients receiving chemotherapy in the previous month were extracted and quality of cancer care indicators examined. RESULTS: Certain elements of medical care were consistently and appropriately documented, including cancer diagnosis and stage, chemotherapy planning, administration, and summary. In general, considering the specific cancer management measures, patients received recommended care in accordance with recognized guidelines. Despite this, a number of important gaps in care were identified, including the assessment and treatment of pain, documentation of chemotherapy intention, symptom and toxicity management, patients' psychosocial status, and provision of a treatment summary at care completion. CONCLUSION: These findings are encouraging in terms of adherence to core treatment guidelines in cancer care in Brazil. However, results suggest important opportunities for improving care across a number of domains, many of which represent a challenge throughout both developing and developed countries. This study may also provide preliminary guidance for enhancing educational and training programs for professionals and students alike, to implement high-quality, comprehensive cancer care.
