About this study

Official title: Loma Linda University Medical Center Department of Radiation Medicine Patient Registry

For most cancers, long-term follow-up is the best measure of treatment effectiveness. The Department of Radiation Medicine at Loma Linda University Medical Center operates the James M. Slater, M.D., Proton Treatment and Research Center, the world's first hospital-based proton treatment facility. Patients have been treated at the Center since 1990. Radiation treatment has been expanded and refined since the Center's opening, and these changes have been based primarily on outcomes seen and evaluated in long-term follow-up.

The Radiation Medicine Patient Registry (a multi-year database), which began as an IRB-approved study in 2003, including detailed follow-up of study data collected from 1990 and onward, is designed to track all medical information from patients treated with proton therapy and/or conventional X-ray therapy at Loma Linda University Medical Center. Information gathered from patients treated years or even decades ago helps to determine the most effective use of proton and conventional radiation in caring for patients with cancers and other diseases.

Read the detailed description

The patient registry will be posted to accomplish three objectives:

  1. Perform retrospective research studies on diseases treated with proton therapy and conventional photon radiation.
  2. Maintain regular and life-long contact with patients in order to obtain current identification, contact information, and self/parent-reported health status. This information is used to generate better understanding of treatment strategies and, in turn, increase benefits to patients.
  3. Enable physicians to review of medical record information and so to identify subjects who may be eligible to participate in future research studies. This requires obtaining permission from registered participants that they may be contacted and asked if they are interested in participating in studies for which they may be eligible, as determined by their medical information contained in the registry.

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer, run by Loma Linda University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 8 May 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Disease-free survival (time frame: One year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02436941, which also lists 22 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2026.
