HIV infection and ART exposure affect tumor TCR repertoire of diffuse large B cell lymphoma.

Department of Pathology and Laboratory Medicine, School of Medicine, University of North Carolina, Chapel Hill, North Carolina, USA.

The most common subtype of lymphoma globally, diffuse large B cell lymphoma (DLBCL), is a leading cause of cancer death in people with HIV. The restructuring of the T cell compartment because of HIV infection and antiretroviral therapy (ART) may have implications for modern treatment selection, but current understanding of these dynamic interactions is limited. Here, we investigated the T cell response to DLBCL by sequencing the T cell receptor (TCR) repertoire in a cohort of HIV-negative (HIV-), HIV+/ART-experienced, and HIV+/ART-naive patients with DLBCL.

Article Synopsis
  • Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma, making up 40% of new non-Hodgkin lymphoma cases and significantly affecting people living with HIV, who have a much higher risk of developing it.
  • The study explores the differences between HIV-positive and HIV-negative DLBCL at a molecular level, revealing that these groups react differently to therapy and have varying clinical outcomes, particularly among those on or off antiretroviral treatment (ART).
  • Findings indicate that HIV+ and ART-naïve patients show more favorable outcomes, while established biomarkers are limited; however, differences in immune responses are linked to tumor interactions, suggesting new therapeutic avenues based on patient status.

Introduction: Research is a critical pillar in national cancer control planning. However, there is a dearth of evidence for countries to implement affordable strategies. The WHO and various Commissions have recommended developing stakeholder-based needs assessments based on objective data to generate evidence to inform national and regional prioritisation of cancer research needs and goals.

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: Burkitt lymphoma (BL) accounts for 90% of pediatric lymphomas in sub-Saharan Africa. Plasmodium falciparum malaria is considered an etiological factor of BL. We describe the geographic distribution of pediatric BL in Malawi and association with P.

Successful Outcomes of Newly Diagnosed T Lymphoblastic Lymphoma: Results From Children's Oncology Group AALL0434.

J Clin Oncol

September 2020

Division of Blood and Marrow Transplantation, Children's National Health System, Washington, DC.

Purpose: The Children's Oncology Group (COG) protocol AALL0434 evaluated the safety and efficacy of multi-agent chemotherapy with Capizzi-based methotrexate/pegaspargase (C-MTX) in patients with newly diagnosed pediatric T-cell lymphoblastic lymphoma (T-LL) and gained preliminary data using nelarabine in high-risk patients.

Patients And Methods: The trial enrolled 299 patients, age 1-31 years. High-risk (HR) patients had ≥ 1% minimal detectable disease (MDD) in the bone marrow at diagnosis or received prior steroid treatment.

Purpose: The National Cancer Institute (NCI)-Designated Cancer Centers (NDCCs) are active in global oncology research and training, leading collaborations to support global cancer control. To better understand global oncology activities led by NDCCs, the NCI Center for Global Health collaborated with ASCO to conduct the 2018/2019 NCI/ASCO Global Oncology Survey of NDCCs.

Methods: Seventy NDCCs received a two-part survey that focused on global oncology programs at NDCCs and non-National Institutes of Health (NIH)-funded global oncology projects with an international collaborator led by the NDCCs.

Challenges and opportunities in the creation and implementation of cancer-control plans in Africa.

National Cancer Institute Center for Global Health, National Cancer Institute, 9609 Medical Center Drive, Rockville, MD 20850, USA.

Article Synopsis
  • Cancer is becoming a major public health crisis in Africa due to an aging population and lifestyle changes, with only 11 countries having a national cancer-control plan (NCCP) in place.
  • The World Health Organization emphasizes that effective NCCPs should focus on reducing cancer incidence and improving the quality of life for patients, but many countries lack the necessary resources to implement these plans.
  • Key strategies for improving NCCPs include mobilizing resources, utilizing accurate data for planning, and forming partnerships to enhance implementation, which can help address the existing capacity challenges faced by many African nations.

Introduction: Lung cancer is the leading cause of years of life lost because of cancer and is associated with the highest economic burden relative to other tumor types. Research remains at the cornerstone of achieving improved outcomes of lung cancer. We present the results of a comprehensive analysis of global lung cancer research between 2004 and 2013 (10 years).

Rare cancers account for 27% of neoplasms diagnosed each year, and 25% of cancer-related deaths in the United States. However, rare cancers show some of the highest response rates to targeted therapies, probably due to identification of oncogenic drivers with little interpatient variability. Although the low incidence of rare cancers makes large-scale randomized trials involving single histologies difficult to perform, drugs have been successfully developed in rare cancers using clinical trial designs that combine microscopic histologies.

Advances in the treatment of childhood cancers have resulted in part from the development of national and international collaborative initiatives that have defined biologic determinants and generated risk-adapted therapies that maximize cure while minimizing acute and long-term effects. Currently, more than 80% of children with cancer who are treated with modern multidisciplinary treatments in developed countries are cured; however, of the approximately 160,000 children and adolescents who are diagnosed with cancer every year worldwide, 80% live in low- and middle-income countries (LMICs), where access to quality care is limited and chances of cure are low. In addition, the disease burden is not fully known because of the lack of population-based cancer registries in low-resource countries.
