OBJECTIVES: Late abdominal irradiation toxicity during childhood included renal damage, hepatic toxicity and secondary diabetes mellitus. We compared the potential of conformal radiotherapy (CRT), helical tomotherapy (HT) and proton beam therapy (PBT) to spare the abdominal organs at risk (pancreas, kidneys and liver- OAR) in children undergoing abdominal irradiation. METHODS: We selected children with abdominal tumors who received more than 10 Gy to the abdomen...

The inactivation of tumor suppressor genes located within 9p21 locus (CDKN2A, CDKN2B) occurs in up to 30% of children with B-cell precursor acute lymphoblastic leukemia (BCP-ALL), but its independent prognostic significance remains controversial. In order to investigate the prognostic impact of deletions and promoter methylation within 9p21, 641 children with newly diagnosed BCP-ALL using methylation specific multiplex ligation-dependent probe amplification (MS-MLPA) were investigated. A total of 169 (26.4%) microdeletions in 9p21 were detected, of which 71 were homozygous...

BACKGROUND: Data about significance of (18)F-FDG positron emission tomography (PET) at interim assessment and end of treatment in pediatric Hodgkin lymphoma (HL) are limited. METHODS: Patients (≤18 years) with HL were prospectively evaluated with contrast-enhanced computed tomography (CECT) and PET combined with low-dose CT(PET-CT) at baseline, post 2 cycles of chemotherapy and post completion of treatment. Revised international working group criteria (RIW) and Deauville (DA) five point-scale for response assessment by PET-CT were used...

The bone marrow is one of the largest organs in the body and is visible in every magnetic resonance (MR) imaging study. It is composed of a combination of hematopoietic red marrow and fatty yellow marrow, and its composition changes throughout life in response to normal maturation (red to yellow conversion) and stress (yellow to red reconversion). MR imaging is highly sensitive for detection of altered marrow signal intensity, and the T1-weighted spin-echo sequence provides the most robust contrast between yellow marrow and disease...

We described an 11-year-old boy suffering from pediatric anaplastic lymphoma kinase-positive anaplastic large cell lymphoma with heart metastasis at diagnosis and arterial tumor embolisms during chemotherapy. Both the heart metastasis and pericardial effusion showed improvement with prednisolone, but numbness and pallor sequentially developed in his lower extremities during the first course of chemotherapy. Contrast-enhanced imaging revealed occlusion of the right anterior tibial artery and left popliteal artery...

Burkitt lymphoma (BL) is >90% EBV-associated when this pediatric cancer is diagnosed in regions heavily burden by endemic Plasmodium falciparum malaria and thus has been geographically classified as endemic BL. The incidence of endemic BL is 10-fold higher compared to BL diagnosed in non-malarious regions of the world. The other forms of BL have been classified as sporadic BL which contain EBV in ∼30% of cases and immunodeficiency BL which occurs in HIV-infected adults with ∼40% of tumors containing EBV...

(18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well-established imaging modality in adult oncological practice. Its role in childhood malignancies needs to be discussed as paediatric malignancies differ from adults in tumor subtypes and they have different tumor biology and FDG uptake patterns. This is also compounded by smaller body mass, dosimetric restrictions, and physiological factors that can affect the FDG uptake. It calls for careful planning of the PET study, preparing the child, the parents, and expertise of nuclear physicians in reporting pediatric positron emission tomography/computed tomography (PET/CT) studies...

Post-transplant lymphoproliferative disease (PTLD) is a severe complication after solid organ transplantation (SOT). Classical Hodgkin lymphoma-type (HL-) PTLD is a rare subtype, and systematic data on treatment and prognosis are lacking. We report on 17 pediatric patients with classical HL-PTLD. HL-PTLD developed late at a median of 8.1 years after SOT. It was commonly EBV-positive (16/17) and expressed both CD30 (all tumors) and CD20 (8/17 tumors). Patients were treated with chemotherapy +/- involved field radiotherapy (IF-RT) according to the respective GPOH-HD protocol tailored by stage and LDH...

STUDY QUESTION: Are Inhibin B and testosterone levels reduced in boys with newly diagnosed cancer prior to therapy? SUMMARY ANSWER: Pretreatment serum levels of Inhibin B and testosterone are significantly reduced in boys with newly diagnosed cancer, compared to reference values. WHAT IS ALREADY KNOWN: Disease-related gonadal impairment has been demonstrated in girls and young women diagnosed with cancer, prior to therapy. STUDY DESIGN, SIZE, DURATION: We conducted a descriptive study in boys newly diagnosed with cancer between January 2006 and February 2014...

To date, there has been a lack of pediatric experience regarding the efficacy and tolerability of immune checkpoint inhibitors after haploidentical hematopoietic stem cell transplant (HSCT). We present the case of a 22-year-old female with multiple-relapsed Hodgkin lymphoma (HL) who presented with a new relapse after haploidentical (post-haplo) HSCT. Anti-PD-1 therapy with nivolumab resulted in significant objective disease response and clinical improvement without notable side effects, including the absence of a graft-versus-host disease (GVHD)...

Phototherapy can be a safe and effective treatment for various skin diseases in children. Special considerations governing the use of this treatment modality in pediatric populations include patient, family, and facility-based factors that are oriented around heightened concerns with regard to safety and tolerability of treatment. Although phototherapy has been found to be effective in a wide range of dermatologic conditions affecting pediatric populations, including psoriasis, atopic dermatitis, pityriasis lichenoides, cutaneous T-cell lymphoma, and vitiligo, there is need for additional research on other conditions in which phototherapy has shown promise...

BACKGROUND: Methionine transport across plasma membranes occurs via large amino acid transporter ( LAT1), which is overexpressed in malignant cells leading to tracer accumulation within tumors. We investigated the uptake of (11)C-methionine in children and young adults newly diagnosed with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) and compared the biodistribution of (11)C-methionine PET-CTs ((11)C- METPET) to that of (18)F-FDG PET-CT ((18)F-FDGPET). METHODS & MATERIALS: Conducted under an IND, we prospectively enrolled patients with newly diagnosed HL (N = 19) and NHL (N = 2) onto the IRB-approved investigation of (11)C-METPET...

Vitamin D receptor (VDR) polymorphisms are found more commonly in some tumor types than in healthy individuals, suggesting that some polymorphisms (Cdx2, Fok1, Bsm1, Apa1, Taq1) contribute to tumor development. There is no previous report on VDR polymorphism in Hodgkin's lymphoma (HL) patients. VDR polymorphism patterns in 95 pediatric HL cases with 100 healthy controls were compared. No statistically significant difference was found between the patient group and control group in terms of Cdx2, Fok1, Bsm1, Apa1, and Taq1 polymorphisms (P>0...

Lymphomas are one of the commonest malignancies in adolescents and young adults (AYA) accounting respectively for 22% of all cancers in patients aged 15-24 years (16% for Hodgkin lymphoma (HL) and 6% for non-HL (NHL)). The distribution of NHL subtypes in this age group differs strikingly from the distribution in children and in older adults with 4 main subtypes accounting for the majority of the cases: diffuse large B-cell lymphoma (DLBCL) including primary mediastinal B-cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma or anaplastic large cell lymphoma...

BACKGROUND: Fine-needle aspiration (FNA) coupled with flow cytometry (FC) can be helpful in suspicious pediatric lymph nodes or masses to exclude a lymphoproliferative disorder. The aim of this study was to analyze FC findings in a series of pediatric FNAs and to correlate abnormal findings with follow-up information. MATERIALS AND METHODS: All pediatric FNAs performed at a tertiary-care children's hospital over a 46-month period that had FC performed were retrospectively analyzed and correlated with follow-up...

Chemotherapy-induced neutropenia (CIN) is the major dose-limiting toxicity of systemic chemotherapy and it is associated with significant morbidity, mortality and treatment cost. The aim of the present study was to identify the risk factors that may predispose pediatric cancer patients who receive myelosuppressive chemotherapy to CIN and associated sequelae. A total of 113 neutropenia episodes were analyzed and the risk factors for CIN were classified as patient-specific, disease-specific and regimen-specific, while the consequences of CIN were divided into infectious and dose-modifying sequelae...
