Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Imaging will be exploratory and be used intraoperatively. There have been no discovered risks associated with the device to be used in this study, and none are anticipated given the diagnostic and non-invasive, 'ex vivo' nature of device use. Of note, the surgical resection will proceed as per standard of care and will not be affected by the research protocol.

Potential Benefit: Imaging intra-operatively will ensure surgeons to identify at risk resection margins.

Time Commitment: There are no additional visits that will be asked of you to partake in this study.

Drug is FDA approved and Exposure to Radiation is minimal.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This pilot study explores the use of high-resolution PET imaging to identify surgical margins in solid tumors after removal. It evaluates the feasibility and potential of using PET-CT to assess tumor specimens and ensures radiation safety with a low-dose 18-FDG injection (20% of the standard dose). Previous studies have shown good tumor visualization in breast, pancreatic, prostate, and head and neck tumors, supporting the method's proof-of-concept. This research aims to gather insights into its clinical usefulness across different cases

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

18F-FDG

After confirming inclusion/exclusion criteria, all participants will receive a one-time IV infusion of 18 F-FDG dose prior to surgical extirpation of tumor. Administration of 18 F-FDG will be injected as a bolus during surgery. Appropriate medical resources for the treatment of severe infusion reactions should be available during infusions, although these are not expected.

Once the tumor or cancer is resected, it will then be imaged with the XEOS Aura 10 PET/CT Imaging Device.

Group Type EXPERIMENTAL

Intra-op PET/CT Specimen Scanner

Intervention Type DEVICE

Once the tumor or cancer is resected, it will then be imaged with the XEOS Aura 10 PET/CT Imaging Device. Imaging will be obtained utilizing a XEOS AURA 10 scanner in real time while in the operating room with the surgery team still present.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Biopsy confirmed diagnosis of any solid malignancy
* Diagnosis of any T stage, any subsite that are scheduled to undergo definitive en bloc surgical resection. Patients with recurrent disease or a new primary will be allowed.
* Planned standard of care oncologic surgery with curative intent
* Male or female patients age ≥ 18 years
* Have life expectancy of more than 12 weeks
* Karnofsky performance status of at least 70% or ECOG/Zubrod level 1
* Have acceptable glucose status (\<200 mg/dL) at Day of Surgery prior to 18F-FDG injection

Exclusion Criteria

* General or local contraindications for resective surgery
* Women who are pregnant or breast-feeding
* Blood glucose level over 200 mg/dL prior to 18F-FDG infusion
* Any participation in other clinical trials or research study that involved a radiation exposure of more than 1 mSv in the past year. If the participant had radiation exposure greater than 1 mSv as SOC, they would not be excluded unless the Principal Investigator determines that patient could be at risk.
