Background: The neutropenic diet (ND) is prescribed to avoid introduction of bacteria into a host's gastrointestinal tract and reduce infection. Due to a lack of evidence to support the ND, there continues to be debate among pediatric oncologists regarding its usefulness. This prospective randomized controlled trial evaluated the difference in neutropenic infection rates in pediatric oncology patients randomized to Food and Drug Administration approved food safety guidelines (FSGs) versus the ND plus FSGs during one cycle of chemotherapy.

Background: The prognostic significance of having extraskeletal (EES) versus skeletal Ewing sarcoma (ES) in the setting of modern chemotherapy protocols is unknown. The purpose of this study was to compare the clinical characteristics, biologic features, and outcomes for patients with EES and skeletal ES.

Methods: Patients had localized ES and were treated on two consecutive protocols using five-drug chemotherapy (INT-0154 and AEWS0031).

Osteosarcoma (OS) and the Ewing sarcoma family of tumors (ESFT) are the most common malignant bone tumors in children and adolescents. While significant improvements in survival have been seen in other pediatric malignancies the treatment and prognosis for pediatric bone tumors has remained unchanged for the past 3 decades. This review and update of pediatric malignant bone tumors will provide a general overview of osteosarcoma and the Ewing sarcoma family of tumors, discuss bone tumor genomics, current challenges, and emerging drug targets.

Article Synopsis
  • The study investigated how different local control (LC) methods for treating Ewing sarcoma (EWS) in the femur affect patient outcomes, analyzing data from 115 patients.
  • It found that most patients underwent surgery (73%), while the rest had varying combinations of surgery and radiation, and the 5-year event-free survival (EFS) was 65% and overall survival (OS) was 70%.
  • The results indicated that the type of LC modality used did not significantly influence the EFS, OS, or the rates of local and distant failures, suggesting that more research on treatment complications is needed.

Article Synopsis
  • Researchers analyzed data from over 2,000 Ewing sarcoma patients to create prognostic groups for better risk classification.
  • A multivariable model identified five distinct groups based on age, primary tumor location, and race/ethnicity that showed significant differences in overall and event-free survival.
  • The findings can help doctors customize treatment plans for Ewing sarcoma, potentially enhancing outcomes in future clinical trials.

Abdominal tumors involving both roots of the celiac and superior mesenteric artery are deemed unresectable by conventional surgical methods. We performed three cases of multivisceral ex vivo surgery involving temporary removal of the entire abdominal viscera followed by vascular reconstruction, ex vivo tumor resection and autotransplantation of excised organs. We achieved a complete tumor resection with negative margins in all cases.

Sialoblastoma is a rare salivary neoplasm which presents either congenitally or during early infancy. It was originally considered a benign neoplasm, however a number of reported cases have documented locoregional recurrence and distant metastases. Currently, there is no consensus on the appropriate treatment for this neoplasm.

Phenomenologic analysis of initial consults provided during the first year of a new Pediatric Advanced Care Team (PACT) program provides essential understanding of the experience and inform program direction and future clinical research. Parents bring to the consult a desire to remain experts in their children's lives yet experience vulnerability as they seek assistance in making critical decisions often under conditions of disquieting uncertainty. Dynamic communication efforts involving the referring providers, PACT team members, and family are a key influence in facilitating consults' stated goals and in establishing the integrated palliative paradigm in a tertiary care environment.

Purpose: The Ewing sarcoma family of tumors (ESFT) is a group of malignant tumors of soft tissue and bone sharing a chromosomal translocation affecting the EWS locus. The Intergroup INT-0091 demonstrated the superiority of a regimen of vincristine, cyclophosphamide, doxorubicin (VDC), and dactinomycin alternating with ifosfamide and etoposide (IE) over VDC for patients with nonmetastatic ESFT of bone. The goal of this study was to determine whether a dose-intensified regimen of VDC alternating with IE would further improve the outcome for patients with nonmetastatic ESFT of bone or soft tissue.

Objectives: Veno-occlusive disease (VOD) following standard chemotherapy has been reported in patients receiving vincristine actinomycin D, and cyclophosphamide for the treatment of Wilms tumor and more rarely rhabdomyosarcoma. The dose and schedule of administration of actinomycin D in patients with Wilms tumor and the increased dose of cyclophosphamide administered to patients with rhabdomyosarcoma have been considered the likely etiology for VOD.

Methods: The authors report four cases of VOD in patients with rhabdomyosarcoma treated with vincristine and actinomycin D only.

Sialoblastoma is an extremely rare salivary tumor diagnosed at birth or shortly thereafter with significant variability in histologic range and clinical course, so that for an individual case it may be difficult to predict the most appropriate therapy. We detail the case of a toddler noted to have a firm 1-2-cm mass in the left cheek at 21 months. Parotidectomy was performed at 26 months, revealing a sialoblastoma; the resection margins were positive.
