Pediatric spinal ependymomas (SEPN) are important albeit uncommon malignant central nervous system tumors with limited treatment options. Our current knowledge about the underlying biology of these tumors is limited due to their rarity. To begin to elucidate molecular mechanisms that give rise to pediatric SEPN, we compared the transcriptomic landscape of SEPNs to that of intracranial ependymom...

Pediatric high-grade gliomas (World Health Organization grades III and IV astrocytomas) remain tumors with a very poor prognosis for which novel therapeutic strategies are needed. Poly(ADP-ribose) polymerase (PARP) is known to have multiple functions in tumors, including single-strand DNA repair and induction of caspase-independent apoptosis. PARP has been suggested as a therapeutic target in a...

Sarcomas are malignant tumors of mesenchymal origin. They comprise < 1% adult malignancies and about 15-20% pediatric malignancies. These subdivided into bone cartilage sarcomas soft tissue type. the maxillofacial region 5-10% all this part body. Usually do not originate from benign tumors. Among factors known to induce sarcoma growth are: genetic defects, exposure pesticides herbicides, ionizi...

The environmental determinants of pediatric embryonal tumors remain unclear. Because of the growing concern over the impact of exposures to traffic-related air pollution on pediatric cancer, we conducted a population-based study evaluating the impact of maternal residential proximity to major roadways on the risk of pediatric embryonal tumors in offspring. We identified children diagnosed with ...

BACKGROUND Chordomas are slow-growing tumors and most commonly involve the sacrum and clivus. Multiple recurrences are frequent. Childhood chordomas are rare and often show exceptionally aggressive behavior, resulting in short survival and a high incidence of metastatic spread. OBJECTIVE This study examined the histologic features and immunohistochemical profile of pediatric chordomas and com...

Background: Pediatric malignancies are extremely heterogeneous yet account for only approximately 1% of all tumor diagnosis. These entities important to recognize because their clinical features non-specific and may mimic common disorders childhood .Pediatric solid malignant tumors clinico-biologically distinct. They more aggressive but usually respond satisfactorily chemotherapy. The advanced ...

A total of forty two clinically diagnosed pediatric brain tumors were studied over a period of two years. The study was aimed to evaluate the efficacy of computed tomography (CT) in pre-operative diagnosis of pediatric brain tumors by correlating the imaging findings with postoperative histopathological findings. Site, density, mass effect and contrast enhancement of the lesion were studied as ...

Brain tumors are the most common solid pediatric malignancy. For high-grade, recurrent, or refractory pediatric brain tumors, radiation therapy (XRT) is an integral treatment modality. In the era of personalized cancer therapy, molecularly targeted agents have been designed to inhibit pathways critical to tumorigenesis. Our evolving knowledge of genetic aberrations in pediatric gliomas is being...

Fibrous or desmoid tumors are grouped under the term fibromatosis; there are several groups; the pediatric aggressive form is rare, especially the pelvis and/or hip presentation. This causes a variable degree of destruction of the surrounding tissues. It is a diagnosis by exclusion and histopathologic testing; treatment is always surgical and conservative treatment is indicated only for special...

The prognosis of malignant solid tumors in children has been improved by multidisciplinary therapy involving surgery, radiotherapy and chemotherapy. High-dose chemotherapy (HDC) followed by autologous (Auto) or allogeneic (Allo) hematopoietic stem cell transplantation (HSCT) has contributed significantly to improvements in the prognosis of high-risk chemosensitive tumors. It has been utilized i...
