Disseminating cells of a primary solid tumor may represent the origin of metastases and relapses. We aimed at comparing the diagnostic efficacy of multicolor flow cytometry (MFC) and morphology/immunohistochemistry (IHC) in the detection of disseminated tumor cells in the bone marrow (BM) and body fluids of patients with solid tumors, and in pediatric neuroblastoma cases. We investigated 72 samples retrospecively from 50 patients by MFC. Morphology/IHC data were available in 48 cases. In the first cohort, 36 samples derived from 34 patients with various forms of suspected and proven solid tumors and in the second cohort, 36 samples of 16 children with suspected and proven neuroblastoma were analyzed at diagnosis or during follow-up in a 4-color setting by MFC, and the results were compared with those obtained by IHC...

Chronic recurrent multifocal osteomyelitis (CRMO) primarily affects children and adolescents, and is characterized by episodic sterile osteomyelitis over several years. No definitive treatment is available. Non-steroidal anti-inflammatory drugs (NSAID) are common first-line agents, but provide limited improvement in bone pain and do not affect disease duration. Several agents are utilized in the case of non-response to NSAID, including corticosteroids, methotrexate, and tumor necrosis factor-blocking agents...

Importance: Although oral metronomic chemotherapy is often used in progressive pediatric solid malignant tumors, a literature review reveals that only small single-arm retrospective or phase 1 and 2 studies have been performed. Skepticism abounds because of the lack of level 1 evidence. Objectives: To compare the effect of metronomic chemotherapy on progression-free survival (PFS) with that of placebo in pediatric patients with primary extracranial, nonhematopoietic solid malignant tumors that progress after at least 2 lines of chemotherapy...

Desmoplastic fibroma (DF) of bone is considered a benign but locally aggressive tumor of fibroblastic origin. DF is rare, representing less than 1% of all bone tumors. Approximately 84% of patients are younger than 30 years. DF has a slow but aggressive growth potential and can recur locally when it has not been completely excised. Complete resection is the treatment of choice to decrease recurrence and morbidity. Mandibular reconstruction is mandatory in pediatric patients to ensure correct craniofacial development...

Hitherto poor outcomes, paucity of data and heterogeneity in International approach to Pediatric NHL (Non-Hodgkin Lymphoma) prompted the need for guidelines for Indian population with vast variability in access, affordability and infrastructure across the country. These guidelines are based on consensus among the experts and best available evidence applicable to Indian setting. Evaluation of NHL should consist of easily doable and rapid tissue diagnosis (biopsy or flow cytometry of peripheral blood/malignant effusions), St Jude/IPNHLSS (International Pediatric Non-Hodgkin Lymphoma Staging System) and risk grouping with CSF (Cerebro-spinal fluid), bone marrow, whole body imaging [CECT (Contrast enhanced computerized tomography) ± MRI (Magnetic resonance imaging)] and blood investigations for LDH (Lactate dehydrogenase), TLS (Tumor lysis syndrome) and organ functions...

Neuroblastoma (NBL) is the most common extra-cranial solid tumor in childhood. High-risk NBL is considered challenging and has one of the least favourable outcomes amongst pediatric cancers. Primary tumor can arise anywhere along the sympathetic chain. Advanced disease at presentation is common. Diagnosis is established by tumor biopsy and elevated urinary catecholamines. Staging is performed using bone marrow and mIBG scan (FDG-PET/bone scan if mIBG unavailable or non-avid). Age, stage, histopathological grading, MYCN amplification and 11q aberration are important prognostic factors utilized in risk stratification...

Peripheral primitive neuroectodermal tumors (pPNETs) are a group of aggressive neoplasms that are most commonly encountered in pediatric patients and may be located in the abdomen, pelvis, thoracopulmonary region and, rarely, in the head and neck region. pPNETs in adults are extremely rare. The present study reports a case of pPNET located in the hip muscles with bone metastasis. The patient was a 44-year-old woman who complained of progressive pain and swelling with a mass near the left hip. Computed tomography (CT) and enhanced CT revealed a soft tissue mass lesion in the hip muscle group measuring 4...

Ewing Sarcoma is the second most common solid pediatric malignant neoplasm of bone and soft tissue. Driven by EWS/Ets, or rarely variant, oncogenic fusions, Ewing Sarcoma is a biologically and clinically aggressive disease with a high propensity for metastasis. However, the mechanisms underpinning Ewing Sarcoma metastasis are currently not well understood. In the present study, we identify and characterize a novel metastasis-promotional pathway in Ewing Sarcoma, involving the histone demethylase KDM3A, previously identified by our laboratory as a new cancer-promoting gene in this disease...

Tumors of the pediatric facial skeleton represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation, and long-term disfigurement. Their treatment often requires a multidisciplinary approach, and radiologists play a pivotal role in the diagnosis and management of these lesions. Although rare, pediatric tumors arising in the facial bones comprise a wide spectrum of benign and malignant lesions of osteogenic, fibrogenic, hematopoietic, neurogenic, or epithelial origin...

Numerous studies of mitochondrial DNA (mtDNA) in cancer have shown differences between mtDNA sequences in tumor and normal tissue and at various stages of cancer treatment in the same patient. However, there is little data on acute lymphoblastic leukemia (ALL), the most common type of leukemia in children. In this study we compared mitochondrial sequence variation in the D-loop region and in 5 genes of mtDNA in bone marrow samples of 6 pediatric patients with ALL at various stages of therapy. We found several common polymorphisms and one variant at position 3688 whose level varied during leukemia treatment...

BACKGROUND: Osteosarcoma (OS) is a common bone malignant tumor, which is the eighth leading form of pediatric cancer. Despite the modern chemotherapeutic development of OS, a number of patients with OS have a high risk of lung metastasis and local relapse after chemotherapy. OBJECTIVE: This review study focused on the role of long non coding RNAs (lncRNAs) in OS progression, and presented update reports on OS treatment by targeting specific lncRNAs. METHOD: We have acquired information on OS and lncRNAs from scientific databases like google scholar, pubmed and scopus, and reviewed for this study...

The use of high-linear energy transfer charged particles is gaining attention as a medical tool because of the emission of radiations with an efficient cell-killing ability. Considerable interest has developed in the use of targeted alpha-particle therapy for the treatment of micrometastases. Moreover, the use of helium beams is gaining momentum, especially for treating pediatric tumors. We analyzed the effects of alpha particles on bone marrow mesenchymal stromal cells (MSCs), which have a subpopulation of stem cells capable of generating adipocytes, chondrocytes, and osteocytes...

The Ewing sarcoma family of tumors typically appears in the second decade of life with regional pain and swelling of a long bone. The following case presents a pediatric patient, aged 4 years, given a diagnosis of Ewing sarcoma of the rib with the initial presentation of respiratory distress, hypoxia, and pleural effusion. Respiratory distress accounts for a large majority of emergency department visits annually, so it is the distinct responsibility of the emergency department physician to avoid premature closure in attributing the most common diagnoses to account for the presenting symptoms...
