Organ Motion and Early Tumor Response Measurement

June 26, 2019 updated by: The Netherlands Cancer Institute

Organ Motion and Early Tumor Response Measurement During Chemotherapy for Esophageal Cancer

To quantify motion based variation of the target volume of the primary tumor over the course of chemoradiotherapy in esophageal cancer patients, and to use this information to calculate appropriate PTV (planning target volume) margins according to the margins recipe for patients receiving trimodality (neoadjuvant chemoradiation and surgery) or definitive chemoradiation in order to personalize radiation treatment, resulting in either better target coverage or a reduction in normal tissue radiation exposure.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A single center prospective observational study will be performed in esophageal cancer patients. This study registers motion of the esophageal tumor, using 4D planning CT scans and repeated 4D CBCT scanning. Motion of fiducial markers inserted into the esophageal wall, will be used as a surrogate for tumor motion in the limited image quality of CBCT scans.

Patients planned for trimodality treatment will additionally be imaged by serial 4D Pet CT and MRI in week 0 (before start chemoradiotherapy), week 3 (during chemoradiotherapy) and week 10 (just prior to surgery) to observe (early) signs of tumor response.

Patients planned for definitive chemoradiation will not receive extra MRI imaging during treatment because of the inability to correlate this imaging with pathological response.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

  • Histologic evidence of invasive adenocarcinoma or squamous cell cancer of the esophagus

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To quantify motion of the esophageal tumor over the course of chemoradiation
Time Frame: 6 weeks

The outcome measures will be assessed by tracking the motion of the fiducial markers at the daily 4D CBCT (four dimensional cone beam CT scan). (primary outcome)

By observing the motion of the fiducial, the exact setup error, breathing motion amplitudes, intra- and inter-fraction motion can be assessed.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 18, 2014

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
