The Prognostic Value of 18F-PFPN PET Imaging in Patients With Malignant Melanoma

February 18, 2023 updated by: Wuhan Union Hospital, China
This is a monocentric prospective study. This study aims to investigate the prognostic value of the novel melanin-targeted imaging modality 18F-PFPN PET in patients with melanoma and seek independent prognostic factors for progression-free survival (PFS) and overall survival (OS). The patients with clinically highly suspected or confirmed melanoma who underwent 18F-PFPN and 18F-FDG PET scans will be enrolled consecutively. Patients' PET images, clinical characteristics, and follow-up information will be collected for prognostic analyses. This study plans to set the sample size as 100 cases.

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

Melanoma is an aggressive malignancy with a high mortality rate. Accurate diagnosis and prognostic risk assessment are essential to the clinical management of melanoma. Melanin is present in most melanoma and has become a potential target for melanoma. This team has successfully synthesized a positron nuclide targeting melanin probe named 18F-PFPN (18F-N-(2-diethylaminoethyl)-4-(2-[2-ethoxy]-ethoxy) pyridine), which has been proven to be safe and well-tolerated. It has shown excellent diagnostic value in both primary and metastatic melanoma. This prospective study was designed to further investigate the prognostic value of 18F-PFPN for melanoma and compare it with the general metabolic imaging agent 18F-FDG. In this study, patients with clinically highly suspected or confirmed melanoma who underwent 18F-PFPN and 18F-FDG PET scans will be enrolled consecutively. Patients' PET images, clinical characteristics, and follow-up information will be collected for prognostic analyses.

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 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
18F-PFPN PET imaging
For clinically suspected or confirmed melanoma patients, targeted melanin-specific imaging 18F-PFPN PET/MR was performed. CT was instead when MRI was contraindicated. PET images, clinical characteristics, and follow-up information will be collected for prognostic analyses.
Drug: 18F-PFPN
18F-PFPN (dose: 3.0-5.4 MBq/kg) will be injected intravenously prior to imaging.
Other Names:
  • 18F-PEG3-FPN
18F-FDG PET imaging
For clinically suspected or confirmed melanoma patients, general metabolic imaging 18F-FDG PET PET/CT was performed. PET images, clinical characteristics, and follow-up information will be collected for prognostic analyses.
Drug: 18F-FDG
18F-FDG (dose: 3.7-5.4 MBq/kg) will be injected intravenously prior to imaging.
Other Names:
  • 18F-fluorodeoxyglucose

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
Progression-free Survival (PFS)
Time Frame: 1-2 years
PFS time is calculated from the date of PET imaging to the first recurrence/progression or death or the endpoint of follow-up. The disease recurrence/progression is confirmed after a thorough review of following-up imaging or pathologic findings.
1-2 years
Overall Survival (OS)
Time Frame: 1-2 years
OS time is defined as the time from PET imaging to death or the endpoint of follow-up.
1-2 years

Primary Completion (Anticipated)

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.
