Trial summary

This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy. Read more about this study

About this study

Official title: Data Collection to Assess Acute and Late Normal Tissue Sequelae in Proton Therapy for Adults

This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To prospectively collect data on acute and late toxicities (including second malignant neoplasms) in patients treated with proton therapy.

II. To collect and store the corresponding radiation dose distribution and imaging data in order to correlate normal tissue response with dose distribution.

SECONDARY OBJECTIVES:

  1. To derive and refine dose-response relationships for normal tissue toxicity after proton therapy.

II. To document and compare symptom burden weekly during treatment and twice a month for 3 months after therapy, using the M.D. Anderson Symptom Inventory (MDASI).

OUTLINE:

Patients undergoing standard of care proton therapy are assessed for toxicities weekly during proton treatment, then from 1 to 3 times up to 90 days from the start of treatment and annually thereafter. Patients also complete questionnaires over 15-20 minutes at baseline, weekly during treatment, and every 2 weeks during follow up for up to 3 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acute toxicities data in patients treated with proton therapy

    Data will be collected from all organs receiving non-negligible proton dose during treatment. For each acute normal-tissue endpoint considered, analyses will be performed using the maximum toxicity score per patient within the 90-day follow-up. Upon analysis, the distribution of observed toxicity scores for each acute normal-tissue endpoint will be reported.

    Measured: Up to 90 days after end of treatment

  2. Late toxicities data in patients treated with proton therapy

    Data will be collected from all organs receiving non-negligible proton dose during treatment. For each late normal-tissue endpoint considered, analyses will be performed using censored time-to-event data corresponding to specified levels of injury (e.g. time to a specific grade >= 2 late toxicity). The log-rank test will be used to compare event times in subgroups of patients with different dosimetric characteristics of treatment (e.g. portion of lung receiving > 20 Gy: <= 40% vs > 40%). In addition, normal-tissue complication probability models will be fitted to data corresponding to incidence of a late endpoint within a specified time frame, with analysis limited to patients having the specified follow-up (e.g. incidence of grade >= 2 late rectal bleeding within 2 years among patients followed for 2 years post-treatment).

    Measured: Starting 90 days or more after the end of radiotherapy

  3. Dose-response relationships for normal tissue toxicity after proton therapy

    Relevant dose-volume response models from the literature, such as the Lyman model, the parallel model, or the critical-element model will be fitted to the data when possible, and model parameter estimates reported. Confidence intervals for model parameter estimates will be derived using the profile-likelihood method.

    Measured: Up to 3 months after therapy

Secondary outcomes (1)
  1. Symptom burden

    Will be documented and compared using the M.D. Anderson Symptom Inventory (MDASI). The initial analysis for symptom data will be primarily descriptive in nature, and will include frequencies, proportions, means, medians, standard deviations, ranges, interquartile ranges, confidence intervals for the means, and box and whisker plots. Potential differences in symptom development between patients and between treatment variables will be explored using longitudinal analysis performed with mixed models.

    Measured: Up to 3 months after therapy

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Carcinoma and Esophageal Carcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.

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: looking for participants now, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Contact Steven J. Frank (713-563-2300, sjfrank@mdanderson.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acute toxicities data in patients treated with proton therapy (time frame: Up to 90 days after end of treatment). The study lists 3 primary outcomes in all. 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 NCT00991094, which also lists 1 linked publication.

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 12 Jun 2026.
