Dinutuximab With Chemotherapy, Surgery and Stem Cell Transplantation for the Treatment of Children With Newly Diagnosed High Risk Neuroblastoma

This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the cancer cells, this is a type of immunotherapy. When chemotherapy and immunotherapy are given together, during the same treatment cycle, it is called chemoimmunotherapy. This clinical trial randomly assigns patients to receive either standard chemotherapy and surgery or chemoimmunotherapy (chemotherapy plus dinutuximab) and surgery during Induction therapy. Chemotherapy drugs administered during Induction include, cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, and doxorubicin. These drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Upon completion of 5 cycles of Induction therapy, a disease evaluation is completed to determine how well the treatment worked. If the tumor responds to therapy, patients receive a tandem transplantation with stem cell rescue. If the tumor has little improvement or worsens, patients receive chemoimmunotherapy on Extended Induction. During Extended Induction, dinutuximab is given with irinotecan, temozolomide. Patients with a good response to therapy move on to Consolidation therapy, when very high doses of chemotherapy are given at two separate points to kill any remaining cancer cells. Following, transplant, radiation therapy is given to the site where the cancer originated (primary site) and to any other areas that are still active at the end of Induction. The final stage of therapy is Post-Consolidation. During Post-Consolidation, dinutuximab is given with isotretinoin, with the goal of maintaining the response achieved with the previous therapy. Adding dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy may be better at treating children with newly diagnosed high-risk neuroblastoma.

Prospective Comprehensive Molecular Analysis of Endocrine Neoplasms

Background: * Endocrine neoplasms (tumors) are among the fastest growing tumors in incidence in the United States. Furthermore, it is often difficult to distinguish between benign or malignant tumors in cancers of the thyroid, parathyroid, adrenal gland, and pancreas. More research is needed to improve detection and treatment options for patients who develop these kinds of cancer. * Researchers are interested in studying the molecular changes that are involved in endocrine cancer development and growth. To collect a sample of tumor specimens and healthy tissue for further study, researchers are specifically looking for samples from participants who are scheduled for surgery or biopsy on endocrine tumors. Objectives: \- To collect samples of precancerous, cancerous, and healthy tissue from individuals who are scheduled for surgery or biopsy of endocrine system tumors. Eligibility: \- Individuals who have a tumor in or around their thyroid, parathyroid, adrenal gland, pancreas, or any neuroendocrine tissue, and are scheduled for surgery at the National Institutes of Health Clinical Center. Design: * Participants in this study will provide blood and urine samples prior to surgery. * During the surgery or biopsy, pieces of the tumor or precancerous growth and pieces of normal tissue near to the tumor will be removed for ongoing and future research. The rest of the tumor or growth will be sent for analysis. * After surgery, participants will receive routine care until discharge, and doctors will discuss possible treatment options. If there is an appropriate NIH protocol, participants may choose to be treated at the NIH. * After discharge, participants will return to the clinic for a routine postoperative check about 6 weeks following the operation, and then may be followed yearly at the Clinical Center or by phone.

MCT for the Harvard/UCSF ROBIN Center

The goal of the Molecular Characterization Trial (MCT) is to obtain biological specimens and data resources from patients enrolled on prospective trials, to ensure that the Harvard/UCSF ROBIN Center accomplishes its key objective of advancing our understanding of the biological mechanisms that underlie how radiation treats tumors but also can cause unwanted side effects. The MCT focuses on collection of research biospecimens before, during, and after radiation. Also critical to the MCT is the deep annotation of these research biospecimens with elements that complement each other to provide a holistic, detailed view of each patient. Annotated elements include those used in the past such as clinical and biological features but extend to factors we have so far neglected but must incorporate in the future such as dosimetry (precise anatomical measurement of radiation dose), artificial intelligence, computational biology, and natural language processing.

Biomarkers of Resiliency In Childhood Cancer Surgery

This observational study is to better understand how children and their families recover after the stress of major surgery for cancer so that investigators can create ways to improve resilience during recovery. The main questions it aims to answer are: 1. Can information obtained from patients and their caregivers wearing smartwatches and answering questionnaires be used to measure how patients are recovering from surgery? 2. Are there specific patterns in patients' circulating proteins and metabolites that are associated with stress after surgery? Participants, including pediatric patients undergoing surgery for cancer and their primary caregiver, will be asked to: * wear a smartwatch * complete questionnaires * allow for extra blood to be drawn for this research study when they are having their regular blood draws for clinical purposes These actions will occur at baseline prior to patients' surgery and then afterwards for up to one year. There are no changes to participants' clinical care or surgical care as a result of the study. Investigators will also collect participants' clinical information and cancer-specific outcomes. Participants will be remunerated for their time.
