Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The first outcome parameter will be the diagnostic performance of interim conventional 18F-FDG PET, dual time-point 18F-FDG PET, and DWI in detecting residual tumor after two cycles of R-CHOP in conventional interim 18 F-FDG PET positive patients, using biopsy results as reference standard. The second outcome parameter will be the diagnostic performance of 89Zr-rituximab PET in determining status of CD20 expression, using biopsy results as reference standard. The third outcome parameter will be the diagnostic performance of interim conventional 18F-FDG PET, dual time-point 18F-FDG PET, DWI, and 89Zr-rituximab PET in predicting end-of-treatment 18F-FDG PET result and disease relapse within two years. | — |
