Clinical Trials

The purpose of this study is to determine whether conventional or new (2D- speckle tracking echocardiography) parameters of left and right ventricular function are impaired during and at the end of proton beam or photon radiotherapy.

The purpose of this research is to gather information on the safety and effectiveness of proton radiation therapy in reducing the number of VT episodes in people like you who continue to experience VT despite treatment with an ICD and undergoing a previous catheter ablation.

Stereotactic ablative body radiotherapy (SABR), or stereotactic body radiotherapy (SBRT), is a specialized form of radiotherapy used to treat prostate cancer with five treatments over two weeks, compared with a conventional eight-week or longer treatment course. The purpose of this trial is to investigate the effect that proton-based SABR has on quality-of-life in patients with localized prostate cancer. The evaluation and treatment will otherwise follow standard of care, and is not considered investigational.

Patients undergo evaluation and medical care in the same way that they would if they were not part of this trial. This may include standard of ...

Currently, only a few international institutions use CIRT to treat pelvic bone sarcomas. Accordingly, data evaluating the potential differences in oncological outcomes, toxicities, and functional outcomes between CIRT and the more readily accessible local therapies of surgery and PT is scarce. For this reason, we propose conducting a prospective comparative effectiveness study evaluating functional outcomes, toxicities, and local control in patients with pelvic bone sarcomas treated with surgery, PT, and CIRT.

The purpose of this study is to determine freedom from ipsilateral breast recurrence occurrences in patients receiving partial breast proton radiation therapy limited to the region of the tumor at 3 years.

The purpose of this study is to compare proton craniospinal irradiation (pCSI) to involved-field radiation therapy (IFRT) for the treatment of breast or non-small cell lung cancer that has spread from where it first started to the cerebrospinal fluid filled space that surrounds the brain and spinal cord (leptomeningeal metastasis).

This study utilizes a shorter course of radiotherapy for patients who need radiation after surgery or without surgery for head and neck cancers. Radiation is typically given in 6-7 weeks for head and neck cancer using X-ray therapy, but this study will administer treatment in approximately 3 weeks. To achieve this shorter course, proton therapy is used. This study aims to determine cancer control at 2 years after study registration. It also aims to determine the rate and duration of grade 3 or higher acute (defined from treatment start to 30 days from radiation completion date) adverse events ...

The overall goal of this project is to survey parents of children who have undergone proton radiation for brain tumors and collect key information that will improve the feasibility of our proposed intervention.  The survey will include questions on experience with proton treatment and opinion regarding a proposed early intervention.

This randomized phase II clinical trial studies the side effects and how well proton beam or intensity-modulated radiation therapy works in preserving brain function in patients with IDH mutant grade II or III glioma. Proton beam radiation therapy uses tiny charged particles to deliver radiation directly to the tumor and may cause less damage to normal tissue. Intensity-modulated or photon beam radiation therapy uses high-energy x-ray beams shaped to treat the tumor and may also cause less damage to normal tissue. Patients will be more likely to be randomized to proton beam radiation therapy. It is not yet known if ...

The purpose of this study is to evaluate the clinical outcomes of lower intensity (mucosal tissue sparing) proton beam therapy after the surgical removal of oropharyngeal tumors in cancer patients who have a favorable level of risk.

The purpose of this study is to determine if the 2-year rate of grade ≥3 treatment-related skin and soft tissue toxicities with comprehensive nodal irradiation for breast cancer using hypofractionated pencil beam scanning proton therapy (PBS-PT) is non-inferior to conventionally-fractionated PBS-PT.

The purpose of this study is to determine if prostate cancer patients treated with proton therapy as compared to IMRT experience improved QOL (validated EPIC instrument measuring bowel, urinary, and sexual QOL).

The purpose of this study is to evaluate how well proton beam radiation therapy compared with intensity modulated photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside the body to the tumor without damaging much of the healthy tissue around it. Intensity modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the tumor without damaging much of the healthy tissue around it. It is not yet known whether proton beam therapy or intensity modulated photon radiotherapy will work better in ...

The purpose of this study is to evaluate whether proton radiation therapy (proton RT) reduces acute gastrointestinal toxicities at the end of treatment compared to intensity modulated radiation therapy (IMRT).

This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention. Phase I studies also try to define the appropriate dose of the investigational therapy to use for further studies. "Investigational" means that the intervention is still being studied and that research doctors are trying to find out more about it.

Retroperitoneal sarcomas are soft tissue tumors located at the far back of the abdomen. Typically, patients with retroperitoneal sarcomas either have surgery for the removal of their tumors alone, or have their tumors removed, followed by standard radiation therapy, ...

The purpose of the Pediatric Proton Consortium Registry (PPCR) is to enroll children who have been treated with proton radiation in the United States in order to describe the population that currently receives protons and better evaluate its benefits over other therapies. The data collected from this study will help facilitate research on proton beam radiation therapy and allow for collaborative research. The PPCR will collect demographic and clinical data which many centers that deliver proton radiation therapy already collect in routine operations.

The purpose of this study is to develop algorithms that will enable earlier identification and testing triggers for COVID-19 in otherwise asymptomatic patients, and to identify baseline characteristics from patients who ultimately test positive for COVID-19 that may predict clinical trajectory during the evolution of disease.
