简要总结
This study aims to develop methods for quantitative imaging of solid tumors in patients who are receiving immunotherapies that have a delayed mechanism of action.
PET imaging with [18F] 2-deoxy-2-(18F)fluoro-D-glucose (FDG) is a potent diagnostic tool and is able to detect melanomas and other tumors, some of which are undetectable by CT. FDG PET is now used commonly in detecting melanoma in humans as melanomas quite consistently have high glucose metabolism. PET with FDG can image the response of tumors to therapy, but has not been extensively evaluated in melanoma nor in immunotherapy for melanoma. PET has been shown to be highly predictive of outcomes of patients following radioimmunotherapy of lymphoma, and has shown changes in tumor glycolysis as early as 7 days after immunotherapy initiation.
In order to develop PET/CT as a tool to detect early evidence of response in patients with solid tumors receiving immune checkpoint blockade, investigators propose to perform PET/CT imaging prior to therapy, again between days 21 and 28, and finally at 4 months post-treatment initiation. Each scan will be assessed qualitatively and quantitatively. Investigators will use the PERCIST criteria to determine peak and maximum standardized uptake values corrected for lean body mass (SUL) in tumor, tumor volumes, and tumor total glycolytic volumes, and will use CT from PET/CT to measure tumor size by immune RECIST criteria. (See section on Outcome Evaluation below.) Investigators will assess whether early changes in tumor metabolism seen on FDG PET are predictive of progression free and overall survival outcomes. Through these systematic pilot studies, investigators hope to better link FDG PET measurements to individual patient responses to immune checkpoint blockade therapy and better understand and refine this emerging and often effective therapeutic approach.

研究组 & 干预措施
Therapeutic response for solid tumors
Adult patients, with documented metastatic melanoma, RCC or NSCLC, about to initiate any line of immune checkpoint blockade therapy will receive a FDG PET scan during mid treatment to check for change in disease.
干预措施: PET/CT imaging with [18F] 2-deoxy-2-(18F)fluoro-D-glucose (FDG) (Radiation)
结局指标
主要结局
Compare FDG PET-based qualitative and quantitative tumor response assessment with standard CT immune RECIST criteria
时间窗: 6 months after completion of standard of care treatment
To compare FDG PET-based qualitative and quantitative tumor response assessment with standard CT immune RECIST criteria in patients receiving immune checkpoint blockade therapy for melanoma, renal cell carcinoma (RCC), and non-small cell lung cancer (NSCLC). Patients will receive 2 standard of care treatment FDG scans, the first scan at the beginning of treatment and the second scan at the end of treatment. The research scan will be done between the first and second scan.
次要结局
- Assess the use of FDG PET as a non-invasive imaging method to detect early evidence of organ inflammation in patients receiving immune checkpoint blockade therapy(6 months after completion of standard of care treatment)
