FDG PET-CT for Lymphoma Radiotherapy Planning Version 1.3

May 18, 2015 updated by: The Leeds Teaching Hospitals NHS Trust

A Pilot Study to Optimise the Use of FDG PET-CT and Deformable Image Co-registration for Lymphoma Radiotherapy Planning

Chemotherapy followed by radiotherapy is used to treat early stage lymphomas with excellent cure rates. However, a significant proportion of these patients develop cancers and heart diseases years later as a result of the radiotherapy. Therefore, there is a move to reduce radiation exposure without compromising cure rates. Radiotherapy is planned using a CT scan taken following chemotherapy when many of the original sites of the lymphoma are no longer visible using a CT scan taken following chemotherapy when many of the original sites of the lymphoma are no longer visible.

In order to safely minimise the volume treated with radiotherapy it is necessary to accurately reconstruct the extent of the lymphoma prior to chemotherapy on this 'planning' CT scan. A PETCT prior to chemotherapy is the best way of demonstrating the original extent of the lymphoma, but is taken in a different position to the radiotherapy treatment position. This aim of this study is to explore whether a PETCT scan taken prior to chemotherapy in the radiotherapy treatment position, in conjunction with advanced software to combine this scan with the subsequent radiotherapy planning CT, can be used to more accurately identify the lymphoma target. The study aims to recruit up to 20 patients with early stage Hodgkin lymphoma or high grade nonHodgkin lymphoma. A routine staging PETCT will be followed at the same session by a PETCT in the radiotherapy treatment position appropriate radiotherapy immobilisation devices. Participation in the study will not affect treatment decisions or the radiotherapy planning process. The PETCT in the radiotherapy planning position will be made available to the treating clinicians. The process of planning radiotherapy will not be systematically altered by the study. The study is aimed at determining how to improve the radiotherapy planning process in the future, in the hope of a reducing in the long term side effects of treatment whilst retaining high cure rates.

Study Overview

Status

Status

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

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
20

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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.
