Patients Methods with any stage diffuse large B-cell lymphoma were treated six R-CHOP-14 followed by rituximab. PET/CT examinations performed at baseline, (and four if patient PET-positive cycles), end treatment. evaluated locally central review. The primary point event-free survival 2 years (2-year EFS). Results Median age 138 evaluable patients 58.5 a WHO performance status 0, 1, or in 56%, 36%, 8% patients, respectively. By local assessment, 83 scans (60%) repo...
