18FDG PET Textural Indices in Adrenal Lesion (ImpactTexture)

July 27, 2018 updated by: University Hospital, Brest

Diagnostic Value of 18FDG PET/CT Textural Indices in Patients With an Adrenal Lesion

Tumors are characterized by a great heterogeneity. Characterizing this intra-tumor heterogeneity is a major challenge in oncology to improve the therapeutic management and move towards personalized medicine adapted to each patient. However, intra-tumor heterogeneity remains rarely used for diagnostic purposes The discovery of an adrenal mass can occur in different circumstances. Detection of an adrenal mass can be done in a context of secreting syndrome, in the assessment of an extra-adrenal neoplasia or fortuitously when performing an imaging for another reason. The etiologies are numerous (cortical tumors, medullary tumors, metastatic lesion of a extra-adrenal neoplasia, others). The adrenal masses can be divided into two categories, depending on whether they are hyperfunctional or not. In patients without an oncological history, an adrenal mass discovered is most often a benign adenoma, but requires an endocrine assessment. In patients with known primary cancer, approximately 30% of the adrenal masses are malignant.

In all cases, the diagnostic procedure includes an imaging assessment to characterize the lesion and an endocrine assessment. CT scan performed without and after intravenous iodinated contrast agent injection is the first-line examination to assess an adrenal mass.

18F-FDG-PET may be indicated as second-line for characterizing an adrenal mass. Adrenal tumor SUVmax (Standard Uptake Value) and adrenal tumor SUVmax / liver SUVmax ratio are routinely used to determine the malignancy of a lesion. Although very useful for assessing the glucose metabolism of a given lesion, these parameters do not allow assessing the heterogeneity of tumor uptake. The texture analysis corresponds to an analysis of the spatial distribution of FDG uptake, and allows, by the calculation of many indices, an evaluation of the heterogeneity of the tumors.

The hypothesis of our study is that the texture parameters could have an additional diagnostic value to improve the performance of conventional quantitative parameters to determine the malignancy of a lesion.

The objective of this study is to investigate the diagnostic value of texture indices in a large cohort of patients presenting an adrenal lesion

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.

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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

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.
March 1, 2018

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.
