PET-based Evaluation of Chemotherapy-induced Brain Damage in Lymphoma Patients -Implication in the Evaluation of Neuro-cognitive Function Alteration (LYMCOTEP)

Positron emission tomography (PET) with 18-fluoro-deoxy-glucose (PET-FDG) is emerging as a promising approach for detecting brain lesions in dementia, among which Alzheimer's disease has been the most widely studied.

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

Detailed Description

Alteration of neuro-cognitive function induced by chemotherapy has been extensively documented in breast carcinoma patients. These modifications consist in the decrease of memory, intellectual capacity, speed analysis, and represent a real limitation for patients, sometimes durable. Aggressive lymphomas (diffuse large B cell lymphomas/DLBCL) represent a common disease, the standard being Rituximab-Cyclophosphamide-Doxorubicine-Vincristine-Prednisone (RCHOP) regiment which contains, as for breast cancer patients, anthracyclines. However, very little is known about the incidence and severity of cognitive function alteration in these patients. The occurrence of such complications should also be facilitated because of frail cognitive states due to age and co-morbidity. Cognitive function alteration is usually measured by neuropsychological tests (NPT) which are easy to handle and sensitive, but could lack specificity, in the context of general degradation which is often observed in hematological patients.

Positron emission tomography with 18-fluoro-deoxy-glucose (PET-FDG) is emerging as a promising approach for detecting brain lesions in dementia, among which Alzheimer's disease has been the most widely studied. In our center, the investigators have already described glucidic hypometabolism in several brain territories associated with Alzheimer's disease and other dementia. Moreover, uptake quantification and topography are useful markers for determining the type of the disease and progression. PET-FDG received very little attention for the detection of chemotherapy-induced brain damages.

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 to 85 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: intervention
  1. PET-FDG brain imaging and NPT should be performed at T0 (within the 15 days before chemotherapy), at Tf (within 1 month after chemotherapy termination), T+12 (Tf+12 months: within the first month after one year of achievement of chemotherapy). Several PET parameters should be calculated: minimal Standard Uptake Value (SUV), maximum SUV, and mean SUV for each of 20 cortical and sub-cortical territories.
  2. NPT scores (3 values) should be correlated with the five better values on PET-FDG.
  3. Each patient will be monitored along a time period of 18 months.
  4. Duration of the study: one year to include the 15 patients with all the exams; 18 months follow-up for each; total of 30 months.
