Abstract
We evaluated the predictive value of interim positon emission tomography (I-PET) after one course of chemoimmunotherapy in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). One hundred and twelve patients with DLBCL were enrolled. All patients had PET/computed tomography (CT) scans performed after one course of chemotherapy (PET-1). I-PET scans were categorized according to International Harmonization Project criteria (IHP), Deauville 5-point scale (D 5PS) with scores 1-3 considered negative (D 5PS > 3) and D 5PS with scores 1-4 considered negative (D 5PS = 5). Ratios of tumor maximum standardized uptake value (SUVmax) to liver SUVmax were also analyzed. We found no difference in progression-free survival (PFS) between PET-negative and PET-positive patients according to IHP and D 5PS > 3. The 2-year PFS using D 5PS = 5 was 50.9% in the PET-positive group and 84.8% in the PET-negative group (p = 0.002). A tumor/liver SUVmax cut-off of 3.1 to distinguish D 5PS scores of 4 and 5 provided the best prognostic value. PET after one course of chemotherapy was not able to safely discriminate PET-positive and PET-negative patients in different prognostic groups.

Using positron emission tomography (PET) response criteria in solid tumours (PERCIST) 1.0 for evaluation of 2'-deoxy-2'-[18F] fluoro-D-glucose-PET/CT scans to predict survival early during treatment of locally advanced non-small cell lung cancer (NSCLC).

Abstract
The demand for early-response evaluation with 2'-deoxy-2'-[18F] fluoro-D-glucose (F-18-FDG) positron emission tomography combined with whole body CT (PET/CT) is rapidly growing. This study was initiated to evaluate the applicability of the PET response criteria in solid tumours (PERCIST 1.0) for response evaluation.
We performed a retrospective study of 21 patients with locally advanced non-small cell lung cancer (NSCLC), who had undergone both a baseline and a follow-up F-18-FDG-PET/CT scan during their treatments. The scans were performed at our institution in the period September 2009 and March 2011 and were analysed visually and according to PERCIST 1.0 by one board-certified nuclear medicine physician. The response was compared with overall survival (OS) and progression-free survival (PFS). The variation in key parameters affecting the F-18-FDG uptake was assessed.
A kappa of 0.94 corresponding to an almost perfect agreement was found for the comparison of the visual evaluation with PERCIST. Patients with partial metabolic response and stable metabolic disease (as evaluated by PERCIST 1.0) had statistically significant longer median time to progression: 8.4 months (confidence interval (CI) 5.1-11.8 months) as compared with 2.7 months (CI 0-5.6 months) in patients classified with progression. The variation in uptake time between baseline and follow-up scans was more than the recommended 15 min in 48% of patients.
PERCIST 1.0 is readily implementable and highly comparable with visual evaluation of response using early F-18-FDG-PET/CT scanning for locally advanced NSCLC patients. In spite of variations in parameters affecting F-18-FDG uptake, evaluation of F-18-FDG-PET/CT during treatment with PERCIST 1.0 is shown to separate non-responders from responders, each with statistically significant differences in both OS and PFS.
