Abstract Background: Pancreatic cancer is one of the most fatal tumors in the world, which incidence and mortality have continued to rise in the past decade. The main challenge in clinical practice for patients with pancreatic cancer is to accurately distinguish malignant lesions from benign ones in early evaluation. This research aims to investigate the value of 18F-FDG PET/CT in diagnosing pancreatic lesions, and compare it with CA19-9, contrast-enhanced CT (CECT), and contrast-enhanced MRI (CEMR).Methods: Cases of patients with suspected pancreatic lesions examined between Jan 1st, 2011 and June 30th, 2017 were retrospectively analyzed. CA19-9, CECT and CEMR within 2 weeks of PET/CT were evaluated. We compared the diagnostic efficacy of PET/CT with CA19-9, CECT and CEMR as well as combined tests.Results: A total of 467 cases were examined in this study, including 293 males and 174 females, with an average age of 57.79 ± 12.68 y (16–95 y). Cases in the malignant group (n=248) had significantly higher SUVmax (7.34 ± 4.17 vs. 1.70 ± 2.68, P < 0.001) and CA19-9 (663.21 ± 531.98 vs. 87.80 ± 218.47, P < 0.001) than those in the benign group (n=219). The sensitivity, specificity and accuracy of PET/CT were 91.9%, 96.3% and 94.0% respectively. Those for CECT were 83.6%, 77.8%, 81.2% respectively; and 91.2%, 75.0%, 81.7% were for CEMR. PET/CT corrected 14.7% (28/191) CECT diagnoses and 12.2% (10/82) CEMR diagnoses. Although the diagnostic efficiency of CA19-9 was acceptable (80.0%, 69.0%, 74.9% respectively), the joint application of PET/CT and CA19-9 could significantly enhance the diagnostic efficiency compared with PET/CT alone (sen 97.4% vs. 90.5%, P =0.0003; spe 100.0% vs. 95.2%, P = 0.0047). Conclusions: PET/CT has sensitivity similar to CECT, CEMR and significantly higher specificity and accuracy, helping reduce false diagnoses of morphological images. Combining PET/CT with CA19-9 could enhance diagnostic efficiency.

464 Background: FDG PET/CT scan (PET) has been approved by Cancer Care Ontario since 2011 for pancreatic cancer patients who have potentially resectable disease. A recent prospective study supported the use of PET in patients with a pancreatic mass and showed improved staging accuracy. Herein, we reviewed the outcomes of PET in the disease staging and management of patients with pancreatic mass at a single academic center. Methods: We collected demographics, CA 19-9 level, CT, MRI and PET results of patients with suspicious pancreas mass followed at Sunnybrook Health Sciences Centre from April to August 2011. We reviewed disease staging after CT/MRI and clinical management decision after PET result. We excluded patients with proven non-primary adenocarcinoma of the pancreas from the analysis. Results: In this cohort, 58 patients had PET scans. 14 patients with non-primary adenocarcinoma of the pancreas were excluded. From 44 patients analyzed, 61% of them were females, median age 70, 19 patients had biliary obstruction with biliary drain, CA 19.9 was elevated preoperatively in 27 patients (level above 1400 was seen in 37% of 44 patients), pancreatic mass median SUV = 4.8 and 7 patients had SUV < 2.5 with no FDG avid at the pancreas mass (both biopsy proven). Ten patients were discovered to have metastatic disease on PET. PET results were discordant with the CT/MRI disease staging in 34% of cases. PET revealed metastatic disease in 7 patients with prior CT or MRI considered to be negative for metastasis. PET showed localized disease in 8 patients with suspicious metastasis on CT or MRI. However, none of the patients underwent pancreatic resection. Clinical management was changed after PET results in 80% of patients with discordant PET and CT/MRI results. Conclusions: In this single-centre retrospective analysis, PET results changed the metastatic disease status depicted by CT or MRI in 34% of patients and clinical management was guided by PET results for the majority of those patients. This supports the use of PET as a tool to guide staging and treatment of pancreas cancer.

PurposeThis study aims to determine the diagnostic performance of whole-body FDG PET/CT plus delayed abdomen PET/MR imaging in the pretherapeutic assessment of pancreatic cancer in comparison with that of contrast-enhanced (CE)-CT/MR imaging.Materials and MethodsForty patients with pancreatic cancer underwent nonenhanced whole-body FDG PET/CT, delayed abdomen PET/MR imaging, and CE-CT/MR imaging. Two nuclear medicine physicians independently reviewed these images and discussed to reach a consensus, determining tumor resectability according to a 5-point scale, N stage (N0 or N positive), and M stage (M0 or M1). With use of clinical-surgical-pathologic findings as the reference standard, diagnostic performances of the two imaging sets were compared by using the McNemar test.ResultsThe diagnostic performance of FDG PET/CT plus delayed PET/MR imaging was not significantly different from that of CE-CT/MR imaging in the assessment of tumor resectability [area under the receiver operating characteristic curve: 0.927 vs. 0.925 (p = 0.975)], N stage (accuracy: 80% (16 of 20 patients) vs. 55% (11 of 20 patients), p = 0.125), and M stage (accuracy: 100% (40 of 40 patients) vs. 93% (37 of 40 patients), p = 0.250). Moreover, 14 of 40 patients had liver metastases. The number of liver metastases detected by CE-CT/MR imaging, PET/CT, and PET/MR imaging were 33, 18, and 61, respectively. Compared with CE-CT/MR imaging, PET/MR imaging resulted in additional findings of more liver metastases in 9/14 patients, of which 3 patients were upstaged. Compared with PET/CT, PET/MR imaging resulted in additional findings of more liver metastases in 12/14 patients, of which 6 patients were upstaged.ConclusionsAlthough FDG PET/CT plus delayed PET/MR imaging showed a diagnostic performance similar to that of CE-CT/MR imaging in the pretherapeutic assessment of the resectability and staging of pancreatic tumors, it still has potential as the more efficient and reasonable work-up approach for the additional value of metastatic information provided by delayed PET/MR imaging.

Aim: To perform a comprehensive analysis of discordances between contrast-enhanced CT (ceCT) and 18F-FDG PET/CT in the evaluation of the extra-cerebral treatment monitoring in patients with stage IV melanoma. Materials and methods: We conducted a retrospective monocentric observational study over a 3-year period in patients referred for 18F-FDG PET/CT and ceCT in the framework of therapy monitoring of immune checkpoint (ICIs) as of January 2017. Imaging reports were analyzed by two physicians in consensus. The anatomical site responsible for discordances, as well as induced changes in treatment were noted. Results: Eighty patients were included and 195 pairs of scans analyzed. Overall, discordances occurred in 65 cases (33%). Eighty percent of the discordances (52/65) were due to 18F-FDG PET/CT scans upstaging the patient. Amongst these discordances, 17/52 (33%) led to change in patient’s management, the most frequent being radiotherapy of a progressing site. ceCT represented 13/65 (20%) of discordances and induced changes in patients’ management in 2/13 cases (15%). The most frequent anatomical site involved was subcutaneous for 18F-FDG PET/CT findings and lung or liver for ceCT. Conclusions: Treatment monitoring with 18F-FDG PET/CT is more efficient than ceCT and has a greater impact in patient’s management.
