OBJECTIVE: To analyze the factors associated with survival in the largest cohort of individuals with HIV and lymphoma so far described in Brazil. DESIGN: A retrospective, observational, multicenter study involving five institutions in São Paulo, Brazil. METHODS: The medical records of consecutive patients with HIV diagnosed with lymphoma between January 2000 and December 2019 were screened. Inclusion criteria consisted of age over 17 years and a biopsy-confirmed diagnosis of lymphoma...

OBJECTIVES: People living with HIV (PLWH) have elevated risk of non-Hodgkin lymphoma (NHL) and other diseases. Studying clonal hematopoiesis (CH), the clonal expansion of mutated hematopoietic stem cells, could provide insights regarding elevated NHL risk. DESIGN: Cohort analysis of participants in the Multicenter AIDS Cohort Study (N = 5,979). METHODS: Mosaic chromosomal alterations (mCAs), a type of CH, were detected from genotyping array data using MoChA...

BACKGROUND: Primary gastric Burkitt lymphoma (PG BL) and malignant pleural mesothelioma (MPM) are rare and aggressive tumors with poor prognosis. HIV and EBV infection have a link in the aetiology of PG BL, while MPM is usually associated with asbestos exposure. Endoluminal bleeding from massive solid tumor, and dyspnea usually due to pleural effusion, are the typical clinical manifestations respectively of PG BL and MPM. In most patients just palliative treatment is indicated. CASE REPORT: A caucasian elderly male, negative for the proven risk factors, presenting respiratory failure due to massive left pleural effusion with severe mediastinal shift...

Antiretroviral therapy (ART) has improved outcomes for human immunodeficiency virus-associated non-Hodgkin lymphoma (HIV-NHL). This is an analysis of 44 patients with HIV with Burkitt lymphoma (HIV-BL) and diffuse large B-cell lymphoma (HIV-DLBCL) treated in Australia over a 10-year period (2009-2019) during the ART and rituximab era. At HIV-NHL diagnosis, the majority of presenting patients had adequate CD4 counts and undetectable HIV viral load <50 copies/mL. More than 80% of patients received chemotherapy with curative intent, rituximab, and concurrent ART with chemotherapy (immunotherapy)...

We performed a retrospective study to analyze the clinical characteristics and outcomes of human immunodeficiency virus-associated Burkitt's lymphoma in Chongqing University Cancer Hospital, southwest China, from March 2012 to February 2022. In the entire cohort, the median age was 36 years (range, 28-60 years), and more patients were male (82.4%). The median CD4+ T cell count was 214/μl (range, 54-601), of whom 47.1% had a CD4+ T cell count below 200/μl. Most patients had elevated lactate dehydrogenase (LDH), elevated β2 -MG, extranodal involvement and advanced Ann Arbor stage at diagnosis...

HIV is still a major public health problem. At present, HIV-associated lymphoma remains the leading cause of deaths among people living with HIV, which should be paid more attention to. 18 F-fluorodeoxglucose (FDG) PET/CT has been recommended in the initial staging, restaging, response assessment and prognostic prediction of lymphomas in general population. HIV-associated lymphoma is, however, a different entity from lymphoma in HIV-negative with a poorer prognosis. The ability to accurately risk-stratify HIV-infected patients with lymphoma will help guide treatment strategy and improve the prognosis...

UNLABELLED: Primary CNS lymphoma (PCNSL) is a rare subtype of non-Hodgkin lymphoma with the worst outcomes amongst all extranodal lymphomas. There is a scarcity of data on real-world outcomes of primary CNS lymphoma (PCNSL) owing to the rarity of the disease. This study analyzed the demographic patterns, risk stratification, treatment regimens used, & outcomes of patients treated at Tata Memorial Center Mumbai, India. This is a retrospective analysis of newly diagnosed primary CNS lymphoma patients treated at our centre over seven years from January 2013 to December 2019...

OBJECTIVES: The purpose of this study was to investigate the clinicopathological characteristics of primary central nervous system lymphoma (PCNSL). METHODS: We collected 41 PCNSL formalin-fixed, paraffin-embedded (FFPE) samples from human immunodeficiency virus (HIV)-positive patients and performed HE (haematoxylin-eosin) staining, immunohistochemistry (IHC) staining, in situ hybridization, fluorescence in situ hybridization (FISH). Real-time quantitative polymerase chain reaction (RT-qPCR) was performed in 9 cases of FFPE samples...

Non-Hodgkin lymphoma is made from the B-cell lineage and includes extra-nodal marginal lymphomas, follicular lymphomas, mantle cell lymphoma, diffuse large B-cell lymphoma, and Burkitt lymphoma. Burkitt lymphoma is associated with Epstein Barr Virus and Human Immunodeficiency Virus. Although it is common for other B-cell lymphomas to develop in the stomach, it is less common for Burkitt lymphoma tumors to manifest there. Additionally, primary and/or secondary involvement of the duodenum, pancreas, and intestines is very rare in Burkitt lymphoma...

CONTEXT: DA-EPOCH-R (dose-adjusted etoposide, doxorubicin, cyclophosphamide, vincristine, prednisolone, and rituximab) is one of the standard chemotherapeutic regimens for Burkitt lymphoma. OBJECTIVE: This study aimed to evaluate the safety and efficacy of DA-EPOCH-R in adult Burkitt lymphoma in an Indian context. DESIGN, SETTING, AND PARTICIPANTS: This retrospective study included 16 patients with adult Burkitt lymphoma who received uniform DA-EPOCH-R protocol, intrathecal methotrexate with each cycle, and GCSF prophylaxis in the Department of Medical Oncology at All India Institute of Medical Sciences, New Delhi, India, from May 1, 2013, to December 2021...

Burkitt lymphoma (BL) is an aggressive type of non-Hodgkin lymphoma (NHL). With high-dose combination chemotherapy, cure rates are excellent. Treatment for HIV-positive BL is similar to that for HIV-negative BL. Offering long-term intensive chemotherapy is difficult in resource-limited settings. Oral metronomic chemotherapy, though in vogue as a treatment modality, has limited evidence of its efficacy in HIV-positive BL. Here, we present the case of a child who was diagnosed with BL and HIV and administered metronomic chemotherapy, and also review the literature on the role of metronomic chemotherapy in non-Hodgkin lymphoma with and without HIV...

AIMS: The frequency of aggressive subtypes of B-cell non-Hodgkin lymphoma (B-NHL), such as high-grade B-cell lymphomas (HGBL) with MYC and BCL2 and/or BCL6 rearrangement (HGBL-DH/TH) or Burkitt-like lymphoma (BL) with 11q aberration is not well known in the HIV-setting. We aimed to characterize HIV-associated aggressive B-NHL according to the 2017 WHO criteria and to identify genotypic and phenotypic features with prognostic impact. Methods and results Seventy-five HIV-associated aggressive B-NHL were studied by immunohistochemistry (CD10, BCL2, BCL6, MUM1, MYC and CD30), EBERs, and FISH to evaluate the status of the MYC, BCL2 and BCL6 genes and chromosome 11q...

Cancer constitutes a major health care burden in the world today with the situation worsening in resource poor settings as seen in most Sub-Saharan African (SSA) countries. Infections constitute by far the most common risk factors for cancer in SSA and being a typical country in this region, Kenya has experienced an upsurge in the incidence of various types of cancers in the last few decades. Although there is limited population-based data in Kenya of infections-associated cancers, this review provides an up-to-date literature-based discussion on infections-associated cancers, their pathogenesis, and preventive approaches in the country...

Access to antiretroviral therapy (ART) led to epidemiological changes in human immunodeficiency virus (HIV) associated lymphoma in high-income countries such as reductions in diffuse large B-cell lymphoma (DLBCL) and stable or increased Hodgkin lymphoma (HL) and Burkitt lymphoma (BL). In 2016, Malawi implemented a universal ART (UART) policy, expanding ART eligibility to all persons living with HIV (PLWH). We compare the distribution of lymphoma subtypes and baseline HIV and prognostic characteristics for lymphoma patients in Malawi before and after implementation of UART...

BACKGROUND: HIV-1 matrix protein p17 was found to be associated with lymphoma development in vitro. This study aimed to elucidate the pathogenetic roles of HIV-1 p17 in AIDS-related lymphoma. METHODS: Expression of HIV-1 proteins p17, p24, nef and tat were evaluated in tumor tissue samples from 60 lymphoma patients and lymph node samples from 23 non-lymphoma patients with HIV-1 infection by immunohistochemistry. Microvascular density (MVD) determined by CD34 were also assessed in tumor tissues...

BACKGROUND: The incidence of Burkitt lymphoma among acquired immunodeficiency syndrome (AIDS) patients is significantly higher than that in general populations. It often features high malignancy and a poor prognosis. For patients with AIDS-related Burkitt lymphoma, the guidelines recommend the dose-adjusted EPOCH-R (DA-EPOCH-R) regimen (rituximab + etoposide vincristine + doxorubicin + cyclophosphamide + dexamethasone) as one of the first-line treatment options. If complete or partial responses are not achieved after first-line treatment, then a second-line regimen such as rituximab + gemcitabine + dexamethasone + cisplatin (R-GDP) or rituximab + ifosfamide + carboplatin + etoposide (R-ICE) can be employed instead...

Radiotherapy is not usually a part of standard Burkitt lymphoma treatment. We aim to assess patient and treatment characteristics of Burkitt lymphoma, particularly RT use, and how they relate to survival. Retrospective cohort of adult patients treated from 2008 to 2019 in an academic hospital. All patients had biopsy-proven Burkitt's lymphoma staged I to IV according to St. Jude's/Murphy staging system. Patients were followed for at least six-months or until death. Forty-eight consecutive patients were selected...

Burkitt lymphoma in HIV-infected patients is seldom seen in the oral cavity, and they are rarely reported in the literature. The clinical manifestations may suggest other tumors or gingival infections, which delays diagnosis and management. Spinal cord involvement is exceptional and only a few cases are reported. We report a case of Burkitt lymphoma in the oral cavity and spinal cord, revealing HIV infection in a 44-year-old patient, who responded well to chemotherapy and antiretroviral treatment and is on remission...

Patients with aggressive B-cell lymphoma and MYC rearrangement at FISH exhibit poor outcome after R-CHOP. In the last decade, 68 patients with Burkitt lymphoma (BL; n=46) or high-grade B-cell lymphoma (single, double or triple hit; HGBCL; n=22) were treated with a dose-dense, short-term therapy termed "CARMEN regimen", at five Italian Centers. Forty-six (68%) patients were HIV-positive. CARMEN included a 36-day induction with sequsingle weekly doses of cyclophosphamide, vincristine, rituximab, methotrexate, etoposide, and doxorubicin plus intrathecal chemotherapy, followed by high-dose-cytarabine-based consolidation...
