Pediatric Hodgkin Lymphoma in Low- and Middle-Income Countries (LMICs). A Narrative Review.

Pediatric Hodgkin lymphoma (HL) is a curable disease for more than 90% of children and adolescents in high-income countries. However, similar results cannot be achieved, particularly for advanced disease, in low- and middle-income countries (LMICs), where challenging socio-economic realities and the consequent scarcity of local resources heavily impact the treatment and patients' outcome. Information regarding the management and outcome of pediatric HL in LMICs is still limited.

Hodgkin Lymphoma in Children: A 16-year Experience at the Children's Welfare Teaching Hospital of Baghdad, Iraq.

Background: Childhood Hodgkin lymphoma (HL) is an eminently curable disease. Good outcomes can be achieved even in resource-limited settings, and the focus is increasingly on limiting long-term toxicity. Contemporary treatment incorporates a risk-stratified, response-adapted approach using multiagent chemotherapy with/without low-dose radiotherapy.

Refractory Burkitt Lymphoma: Diagnosis and Interventional Strategies.

Despite excellent results in frontline therapy, particularly in pediatric age, refractory Burkitt lymphoma still remains a therapeutic challenge, with dismal outcome. The prognosis is very poor, ranging from less than 10% to 30-40%, with longer survival only in transplanted patients. On account of the paucity of data, mostly reporting on small series of patients, with heterogeneous characteristics and salvage treatments, at present it is impossible to draw definitive conclusions on the treatment of choice for this difficult to treat subset of patients.

Management of collagenous gastritis in children: Case series and literature review.

Collagenous gastritis (CG) is a rare histopathological finding on gastric biopsies in children. It is associated with abdominal pain and iron deficiency anemia, usually not respondent to oral iron supplements. The aim of this study was to describe our experience in the management of pediatric patients with CG.

Peripherally inserted central venous catheter for pediatric acute leukemia: A retrospective 11-year single-center experience.

Background: Peripherally inserted central catheters (PICCs) are successfully increasingly used in children in onco-hematologic setting. PICC insertion, especially in oncologic patients, can be associated with adverse events (thrombosis, mechanical complications, and infections). Data regarding the use of PICC, as long-term access in pediatric patients with severe hematologic diseases, are still limited.

Pediatric Autologous Hematopoietic Stem Cell Transplantation: Safety, Efficacy, and Patient Outcomes. Literature Review.

Autologous stem cell transplantation (auto-HSCT) is a part of the therapeutic strategy for various oncohematological diseases. The auto-HSCT procedure enables hematological recovery after high-dose chemotherapy, otherwise not tolerable, by the infusion of autologous hematopoietic stem cells. Unlike allogeneic transplant (allo-HSCT), auto-HSCT has the advantage of lacking acute-graft-versus-host disease (GVHD) and prolonged immunosuppression, however, these advantages are counterbalanced by the absence of graft-versus-leukemia.

Childhood acute promyelocytic leukemia in a pediatric cancer referral center in Baghdad, Iraq. Improved results with ATRA extended consolidation.

Modern treatments have dramatically improved the prognosis of childhood acute promyelocytic leukemia (APL). This progress has not yielded equivalent benefit in developing countries, where biological studies and supportive cares are insufficient and often unavailable. Since 2003, an all-trans retinoic (ATRA)-based, risk-adapted protocol was initiated in Baghdad.

Comprehensive global collaboration in the care of 1182 pediatric oncology patients over 12 years: The Iraqi-Italian experience.

Background: Iraq's health care system has gradually declined after several decades of wars, terrorism, and UN economic sanctions. The Oncology Unit at Children's Welfare Teaching Hospital (CWTH) in Baghdad was lacking basic facilities and support. To address this shortcoming, a humanitarian and educational partnership was established between CWTH and Sapienza University of Rome (SUR).

FLT3-ITD in Children with Early T-cell Precursor (ETP) Acute Lymphoblastic Leukemia: Incidence and Potential Target for Monitoring Minimal Residual Disease (MRD).

Early T-cell precursor (ETP) is an aggressive form of acute lymphoblastic leukemia (ALL), associated with high risk of relapse. This leukemia subtype shows a higher prevalence of mutations, typically associated with acute myeloid leukemia (AML), including RAS and FLT3 mutations. FLT3-ITD was identified in 35% cases of adult ETP-ALL, but data in the pediatric counterpart are lacking.

Has Hematopoietic Stem Cell Transplantation a Role in the Treatment of Children and Adolescents with Acute Promyelocytic Leukemia?

The past three decades have brought major therapeutic advances in treating acute promyelocytic leukemia (APL) both in adults and children. The current state-of-the-art treatment with all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) in combination or not with chemotherapy results in long-lasting remission and cure in more than 90% of newly diagnosed patients. These treatments have made relapse a rare event.

Blinatumomab in Children and Adolescents with Relapsed/Refractory B Cell Precursor Acute Lymphoblastic Leukemia: A Real-Life Multicenter Retrospective Study in Seven AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica) Centers.

Five-year event-free survival in pediatric B-cell precursor acute lymphoblastic leukemia (BCP-ALL) currently exceeds 80-85%. However, 15-20% of patients still experience a relapsed/refractory disease. From 1 January 2015 to 31 December 2020, thirty-nine patients, 0-21 years old with r/r BCP-ALL were treated with blinatumomab with the aim of inducing remission ( = 13) or reducing MRD levels ( = 26) in the frame of different multiagent chemotherapy schedules, in seven AIEOP centers.

Childhood aggressive B-cell non-Hodgkin lymphoma in low-middle-income countries.

In high-income countries (HICs) paediatric aggressive B-cell lymphomas are curable in about 90% of cases. Much worse results, with cure rates ranging from less than 30% to about 70%, are achieved in low- and middle-income countries (LMICs), where 90% of paediatric non-Hodgkin lymphomas occur. Low socio-economic and cultural conditions, the lack of optimal diagnostic procedures, laboratory facilities and adequate supportive care exert a strong negative impact on compliance, treatment delivery, toxicity and, consequently, on the clinical outcome.

Reduced mortality from KPC-K.pneumoniae bloodstream infection in high-risk patients with hematological malignancies colonized by KPC-K.pneumoniae.

Background: KPC-K.pneumoniae bloodstream infection (KPC-KpBSI) mortality rate in patients with hematological malignancies is reported about 60%. The initial treatment active against KPC-K.

Treatment of childhood acute lymphoblastic leukemia in Iraq: a 17-year experience from a single center.

We performed a retrospective analysis of 1415 acute lymphoblastic leukemia children diagnosed between January 2000 and December 2016 at Children Welfare Teaching Hospital, Baghdad, Iraq. Patients were divided into three cohorts according to treatment period (2000-2005; 2006-2011; 2012-2016). Treatments were based on modified-UKALL protocols; a steroid-pre-phase was introduced from September 2008.

Myeloid Sarcoma: Diagnostic and Treatment Tools from a Monocentric Retrospective Experience.

Myeloid sarcoma (MS) is a very rare disease in both adults and children. Prognosis is poor in adults; in the pediatric age, the prognostic impact of extramedullary disease is controversial. Systemic therapy represents the mainstay of treatment even in isolated MS, but a comparison between different induction regimens is very limited in the literature.
