Correlation of HER2 Expression With Uptake of 64Cu-DOTA-trastuzumab by PET Imaging. [ Time Frame: Up to 1 year ]
The reading of the 64CuDOTA-trastuzumab-PET imaging of the study subjects were performed by two radiologists, one who read the first scan and the second nuclear radiologist read the remaining seven scans. To eliminate potential bias, the second nuclear radiologist was blinded to the HER2 status of the tumors as well as the location of the tumor until radiolabeled uptake was measured. XD (version 3.6; Miranda Medical) was used for image analysis.Tumor visualized as "hot" relative to adjacent tissue reported per radiologist as negative, positive, equivocal or unknown.
Original Primary Outcome Measures  ICMJE
 (submitted: September 10, 2013)
  • Tumor uptake of copper Cu 64-DOTA trastuzumab [ Time Frame: Up to 1 year ]
    Parameterized in terms of single-voxel maximum values peak standardized uptake value (SUVmax) and whole-tumor volumes of interest (SUVwhtum). Ratios of tumor to non-tumor activity concentration will be calculated. Receiver-operator curve (ROC) analysis will be performed to estimate optimal cutoff values of SUVmax, SUVwhtum, tumor:background, and tumor:organ ratios for classifying tumors as "HER2 positive" or "HER2 negative".
  • Percent of patients whose tumors image with Cu-PET [ Time Frame: Up to 1 year ]
    Estimated with a 95% confidence interval (CI) half-width of 21%.
  • Percent of samples where the surgeon was confident they could identify areas on the tumor that corresponded to high or low areas of Cu-PET uptake [ Time Frame: Up to 1 year ]
    Estimated with a 95% CI half-width of 21%.
  • Pathologic confirmation of Cu-PET SUV variation over the tumor [ Time Frame: Up to 1 year ]
    Positive and negative areas of the tumor will be sent to pathology for confirmation. This will be exploratory.
  • Pathologic confirmation of Cu-PET SUV positive or negative cases [ Time Frame: Up to 1 year ]
    Correlative of Cu-PET SUV (measured as peak SUV) and pathology will be explored. As correlation requires a continuous measure from pathology, and some pathology will use FISH and/or IHC, this will be exploratory. Comparing Cu-PET in positive cases versus negative by pathology will depend on the percent of patients deemed positive.

Descriptive Information
Brief Title  ICMJE 64Cu DOTA-Trastuzumab PET/CT in Studying Patients With Gastric Cancer
Official Title  ICMJE 64Cu-DOTA-trastuzumab Positron Emission Tomography in Patients With Gastric Cancer
Brief Summary This pilot clinical trial studies copper Cu 64 (64Cu) tetra-azacyclododecanetetra-acetic acid (DOTA)-trastuzumab positron emission tomography (PET)/computed tomography (CT) in studying patients with gastric, or stomach cancer. Diagnostic procedures, such as copper Cu 64-DOTA-trastuzumab PET/CT, may help doctors study the characteristics of tumors and choose the best treatment.
Detailed Description


I. To compare tumor uptake of 64Cu-DOTA-trastuzumab (copper Cu 64-DOTA-trastuzumab) in gastric cancer patients with pathologic evaluation of tumor human epidermal growth factor receptor 2 (HER2)/neu expression.

II. To compare copper Cu 64-DOTA-trastuzumab-PET-CT scan with standard radiographic imaging for staging patients with gastric cancer.


Patients receive copper Cu 64-DOTA-trastuzumab intravenously (IV) on day 1 and then undergo PET/CT scan on days 2 or 3.

After completion of study, patients are followed up for 15 days and periodically for up to 6 months.
