- BackgroundPancreatic cancer often presents as locally advanced (LAPC) or borderline resectable (BRPC). Neoadjuvant systemic therapy is recommended as initial treatment. It is currently unclear what chemotherapy should be preferred for patients with BRPC or LAPC.MethodsWe performed a systematic review and multi-institutional meta-analysis of patient-level data regarding the use of initial systemic therapy for BRPC and LAPC. Outcomes were reported separately for tumor entity and by chemotherapy regimen including FOLFIRINOX (FIO) or gemcitabine-based.ResultsA total of 23 studies comprising 2930 patients were analyzed for overall survival (OS) calculated from the beginning of systemic treatment. OS for patients with BRPC was 22.0 months with FIO, 16.9 months with gemcitabine/nab-paclitaxel (Gem/nab), 21.6 months with gemcitabine/cisplatin or oxaliplatin or docetaxel or capecitabine (GemX), and 10 months with gemcitabine monotherapy (Gem-mono) (p < 0.0001). In patients with LAPC, OS also was higher with FIO (17.1 months) compared with Gem/nab (12.5 months), GemX (12.3 months), and Gem-mono (9.4 months; p < 0.0001). This difference was driven by the patients who did not undergo surgery, where FIO was superior to other regimens. The resection rates for patients with BRPC were 0.55 for gemcitabine-based chemotherapy and 0.53 with FIO. In patients with LAPC, resection rates were 0.19 with Gemcitabine and 0.28 with FIO. In resected patients, OS for patients with BRPC was 32.9 months with FIO and not different compared to Gem/nab, (28.6 months, p = 0.285), GemX (38.8 months, p = 0.1), or Gem-mono (23.1 months, p = 0.083). A similar trend was observed in resected patients converted from LAPC.ConclusionsIn patients with BRPC or LAPC, primary treatment with FOLFIRINOX compared with Gemcitabine-based chemotherapy appears to provide a survival benefit for patients that are ultimately unresectable. For patients that undergo surgical resection, outcomes are similar between GEM+ and FOLFIRINOX when delivered in the neoadjuvant setting.

- Introduction: Natural history of cystic pancreatic neuroendocrine neoplasms (cPanNENs) is unknown, and their clinical management remains unclear. An observational strategy for asymptomatic cPanNENs ≤2cm has been proposed by recent guidelines, but evidence is scarce and limited to single-institutional series.Aim(s): Analyze a large international cohort of cPanNENs.Materials and methods: All resected cPanNENs (1995-2017) from 16 institutions worldwide were included. Solid lesions (>50% solid component), functional tumors and MEN-1 patients were excluded. Malignancy was defined as G3 grading, lymph node (LN) involvement, metastasis and/or recurrence.Results: Overall, 263 resected cPanNENs were included, among which 177 (63.5%) were preoperatively >2cm. A preoperative diagnosis of cPanNEN was established in 162 cases (61.6%) and was more frequent when patients underwent endoscopic ultrasound (EUS, OR 3.01, 95%CI 1.66-5.44) and nuclear medicine investigations (OR 3.97, 95%CI 1.93-8.18), and for those managed in high-volume institutions (OR 3.48, 95%CI 1.88-6.45). Forty-one cPanNENs (15.6%) were malignant. Suspicion of LN involvement on imaging, age >65 years, preoperative size >2cm and pancreatic duct dilation were independently associated with malignancy in the whole cohort. In asymptomatic patients, older age and a preoperative size >2cm remained independently associated with malignancy. Notably, malignancy occurred in only 1/61 asymptomatic patients with a preoperative size ≤2cm.Conclusion: The diagnostic accuracy of cPanNENs is increased by the use of EUS and nuclear medicine investigations and is higher in high-volume institutions. A preoperative size >2cm is independently associated with malignancy, so that a wait-and-see policy for sporadic asymptomatic cPanNENs≤ 2cm seems justified.
