View original scientific description
The Johns Hopkins Proton Therapy center is establishing a registry to capture the full 3D radiation dosimetry delivered to the patient, baseline clinical data, and disease, toxicity and quality of life outcomes. The goal is to have all patients treated at the proton center to be included in the registry to enable future comparisons of treatment outcomes to assist in understanding which patients can benefit from the use of protons.

Registry
Registry of cancer patients who receive proton radiation therapy
Primary outcome measures
Research registry of cancer patients receiving proton radiation therapy
Time frame: 15 years
This is a clinic based registry of cancer patients' data from participants to be collected over 15 years. The registry will be populated with 3D anatomy and radiation dosimetry from the RayStation treatment planning system used to plan all proton therapy patients. Clinical data will be extracted electronically from the MOSAIQ oncology information system used to manage the radiation therapy treatments. Structured clinical assessments will be routinely captured in the clinical workflow during patient encounters. Patient reported outcomes will be captured with iPad's using the OncoBrowser tools developed in radiotherapy that also interface with MOSAIQ.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
