Integration of Adaptive Proton Therapy in Pediatric Solid Tumors and Hodgkin's Lymphoma
Pediatric patients receiving proton therapy for solid tumors or Hodgkin's lymphoma may experience anatomical changes during treatment that can affect proton therapy accuracy. This prospective single-arm study uses regular low-dose imaging to monitor these changes and adjust treatment plans as needed. Participants will receive weekly or every-other-week CT scans, with MRI when appropriate, to assess whether the original plan remains accurate. Treatment plans will be updated if tumor coverage decreases by more than 5% or if radiation dose to normal tissues increases by more than 10%; otherwise, the original plan will continue. The study aims to determine how often plan adjustments are needed and to identify which disease sites are most likely to experience significant anatomical changes during treatment. Primary Objective: * Define the frequency of replanning necessary to ensure tumor coverage never falls below 95% (or 5% drop) of the prescribed daily dose in participants with intact (gross) tumors to keep the tumor control optimal throughout the multi-week treatment regimen. * Define the frequency of replanning necessary to ensure organs-at-risk (critical organs) do not deviate by more than 10% of the initially approved dose constraints to keep the normal tissue complication minimal throughout the multi-week treatment regimen. Secondary Objectives * Establish a cone beam CT (CBCT)-based framework for quantifying body surface changes throughout the treatment course. This goal will be achieved by developing a novel algorithm that detects and tracks external anatomical variations longitudinally, without requiring CBCT image enhancement, enabling precise assessment of daily participant setup consistency and anatomical stability. * Overcome daily CBCT quality limitations by generating synthetic CT images that accurately represent daily anatomy and support proton dose recalculation or verification planning. This goal will be achieved by developing a hybrid pipeline that integrates deep learning models with the deformable image registration algorithm, trained and validated on disease site-specific data. This will enable precise dose mapping and tissue density estimation, directly supporting adaptive planning decisions without the need of diagnostic- quality CT images.

Alpha/Beta T and B Cell Depletion With Zoledronic Acid for Solid Tumors
Hematopoietic stem cell transplantation can cure patients with blood cancer and other underlying diseases. αβ-T cell and B cell depletion has been introduced to decrease GVHD and PTLD and has demonstrated effectiveness for hematologic malignancies and non-malignant diseases additionally increasing the donor pool as to allow for haploidentical transplant to safely occur. While solid tumors can be highly chemotherapy sensitive, many remain resistant and require multimodalities of treatment. Immunotherapy has been developed to harness the immune system in fighting solid tumors, though not all have targeted effects. Some solid tumors are treated with autologous transplants; however, they do not always demonstrate an improved event free survival or overall survival. There has been evidence of the use of allogeneic stem cell transplants to provide a graft versus tumor effect, though studies remain limited. By utilizing αβ-T cell and B cell depletion for stem cell transplants and combining with zoledronic acid, the immune system may potentially be harnessed and enhanced to provide an improved graft versus tumor effect in relapsed/refractory solid tumors and promote an improved event-free survival and overall survival. This study will investigate the safety of treatment with a stem cell graft depleted of αβ-T cell and CD19+ B cells in combination with zoledronic acid in pediatric and young adult patients with select solid tumors, as well as whether this treatment improves survival rates in these patients.

Biologically-Adapted, Dose-Escalated Radiotherapy for the Treatment of Ewing Sarcoma, BEAR Trial
This clinical trial evaluates the effect of radiotherapy doses based on tumor size and tumor-specific characteristics (biologically-adapted) in treating patients with Ewing sarcoma. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Conventional radiotherapy uses minimal imaging support to determine the positioning of radiotherapy. Hypofractionated radiotherapy delivers higher doses of radiotherapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Dose-escalated radiotherapy uses doses that are higher than those used in conventional radiotherapy. Larger tumor sizes and other tumor-specific characteristics have been shown to be related to poorer outcomes. In addition, after dose-escalated radiotherapy, patients with larger tumors have demonstrated improved control of the disease at the primary tumor site. Giving biologically-adapted, dose-escalated radiotherapy may reduce the return of the cancer at the primary tumor site in patients with Ewing sarcoma with large tumors and other unfavorable characteristics. This clinical trial also evaluates the role of biomarkers in patients with Ewing sarcoma. Studying samples of blood and tumor tissue from patients with Ewing sarcoma in the laboratory may help doctors learn more about predicting the amount of disease and the likelihood of the cancer coming back.

HER2 Chimeric Antigen Receptor (CAR) T Cells in Combination With Checkpoint Blockade in Patients With Advanced Sarcoma
The purpose of this study is to learn whether it is safe to give HER2-CAR T cells in combination with an immune checkpoint inhibitor drug (pembrolizumab or nivolumab), to learn what the side effects are, and to see whether this therapy might help patients with sarcoma. Another goal of this study is to study the bacteria found in the stool of patients with sarcoma who are being treated with HER2 CAR T cells and immune checkpoint inhibitor drugs to see if the types of bacteria influence how well the treatment works. The investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. They now want to see if they can put a new gene in these cells that will let the T cells recognize and kill sarcoma cells. The new gene that the investigators will put in makes an antibody specific for HER2 (Human Epidermal Growth Factor Receptor 2) that binds to sarcoma cells. In addition, it contains CD28, which stimulated T cells and make them last longer. After this new gene is put into the T cell, the T cell becomes known as a chimeric antigen receptor T cell or CAR T cell. In another clinical study using these CAR T cells targeting HER2 as well as other studies using CAR T cells, investigators found that giving chemotherapy before the T cell infusion can improve the effect the T cells can have. Giving chemotherapy before a T cell infusion is called lymphodepletion since the chemotherapy is specifically chosen to decrease the number of lymphocytes in the body. Decreasing the number of the patient's lymphocytes first should allow the infused T cells to expand in the body, and potentially kill cancer cells more effectively. The chemotherapy used for lymphodepletion is a combination of cyclophosphamide and fludarabine. After the patient receives the lymphodepletion chemotherapy and CAR T cells during treatment on the study, they will receive an antibody drug called an immune checkpoint inhibitor, pembrolizumab or nivolumab. Immune checkpoint inhibitors are drugs that remove the brakes on the immune system to allow it to act against cancer.

Methionine PET/CT Studies In Patients With Cancer
The purpose of this study is to test the usefulness of imaging with radiolabeled methionine in the evaluation of children and young adults with tumor(s). Methionine is a naturally occurring essential amino acid. It is crucial for the formation of proteins. When labeled with carbon-11 (C-11), a radioactive isotope of the naturally occurring carbon-12, the distribution of methionine can be determined noninvasively using a PET (positron emission tomography) camera. C-11 methionine (MET) has been shown valuable in the monitoring of a large number of neoplasms. Since C-11 has a short half life (20 minutes), MET must be produced in a facility very close to its intended use. Thus, it is not widely available and is produced only at select institutions with access to a cyclotron and PET chemistry facility. With the new availability of short lived tracers produced by its PET chemistry unit, St. Jude Children's Research Hospital (St. Jude) is one of only a few facilities with the capabilities and interests to evaluate the utility of PET scanning in the detection of tumors, evaluation of response to therapy, and distinction of residual tumor from scar tissue in patients who have completed therapy. The investigators propose to examine the biodistribution of MET in patients with malignant solid neoplasms, with emphasis on central nervous system (CNS) tumors and sarcomas. This project introduces a new diagnostic test for the noninvasive evaluation of neoplasms in pediatric oncology. Although not the primary purpose of this proposal, the investigators anticipate that MET studies will provide useful clinical information for the management of patients with malignant neoplasms.

Phase Ib / Regorafenib With Conventional Chemotherapy/Newly Diagnosed Patients/ Multimetastatic Ewing Sarcoma
New drug efficacy in ES has been disappointing in the last decades and no new drugs have been successfully introduced up to now in front line treatment. Among the tested drugs, early clinical data suggest that strategies using multi-targeted tyrosine kinase inhibitors (TKI) with anti-angiogenic activities are among the most efficient and may be beneficial in the treatment of patients with ES. Several TKI have been and are currently being tested as single-agent in patients with relapsed/refractory ES with encouraging results in phase II trials. Regorafenib has shown promising activity in Ewing sarcoma relapse setting, Nevertheless, regorafenib has never been combined with the intensive chemotherapy VDC/IE schedule and therefore this combination needs to be evaluated in order to avoid dose reduction of the current standard treatment and hence its efficacy. The current clinical trial has been therefore designed to test the feasibility of regorafenib with ES conventional chemotherapy. It consists of a phase Ib that will only recruit patients with multi-metastatic (other than lungs/pleura only) ES, that present the highest unmet medical need (2 year EFS: 33%, similar to patients with relapse/refractory ES).
