    Abstract Purpose: Data regarding the clinical management and follow-up of pancreatic neuroendocrine tumors (PanNETs) associated with Von Hippel-Lindau (VHL) syndrome are limited. This study aimed to assess clinical presentation, genotype-phenotype correlations, treatment and prognosis of PanNETs in a series of VHL syndrome patients.
    Methods: Retrospective analysis of data of patients observed between 2005 and 2020.
    Results: Seventeen patients, including 12 probands and 5 relatives (mean age 30.8 ± 18.4; 7 males), were recruited. PanNETs were found in 13/17 patients (77.5%) at a median age of 37 years: 4/13 (30.7%) at the time of VHL diagnosis and 9 (69.3%) during follow up. Six (46.1%) PanNET patients underwent surgery, whereas seven were conservatively treated (mean tumor diameter: 40 ± 10.9 vs. 15 ± 5.3 mm respectively). Four patients (30.7%) had lymph node metastases and a mean tumor diameter significantly larger than the nonmetastatic PanNETs (44.2 ± 9.3 vs. 17.4 ± 7 mm, p = 0.00049, respectively). Five (83.3%) operated patients had stable disease after a median follow up of 3 years whereas one patient showed liver metastases. Six (85.7%) non-resected PanNETs were stable after a median follow-up of 2 years, whereas one patient developed a new small PanNET and a slight increase in diameter of a pre-existing PanNET. No correlation was found between the type of germline mutation and malignant behavior of PanNETs.
    Conclusions: PanNETs are a common disease of the VHL syndrome and can be the presenting feature. Tumor size rather than genetic mutation is a prognostic factor of malignancy.

    Abstract Background: The minimally invasive approach in spleen-preserving distal pancreatectomy has currently been emphasized in benign and pre-malignant pancreatic diseases. The study aims to demonstrate the safety and feasibility of our technique of robotic spleen-preserving distal pancreatectomy (RSPDP) by a stepwise approach.
    Methods: The data of consecutive patients presented for RSPDP from 2014 to 2019 at Verona University were retrieved from a prospectively maintained database. The patients were divided into two groups based on the surgical procedure performed, such as Kimura's (KG) or Warshaw's (WG) technique, and then compared.
    Results: In the study period, 32 patients underwent RSPDP. Twenty-three patients presented for the Kimura procedure (72%), while nine patients underwent the Warshaw procedure (28%). A higher body mass index was found in the KG (26 ± 4 vs. 22 ± 3, p = 0.037). Regarding the pathological data, the WG group differed in the tumor dimension, and the lymph nodes harvested (30 ± 2 vs. 17 ± 10, 9 ± 5 vs. 3 ± 4, p = 0.0028, and p = 0.005, respectively). Notably, no conversions and mortality were recorded. The overall morbidity was 25% ( eight patients) with no difference between the groups (p = 0.820). The mean length of stay was 8 days, and was similar between the groups (p = 0.350).
    Conclusions: The present study suggests that RSPDP is a valid option for the treatment of benign or pre-malignant pancreatic diseases of the distal pancreas, with comparable morbidity with the standard treatment and no mortality. Further research is needed to standardize the technique and to assess the immunological, surgical, and financial benefits of the procedure.

    Abstract Background: The study aims to assess the safety and feasibility of the robotic dual-console during a robotic distal pancreatectomy METHODS: The data of the consecutive patients submitted to RDP from 2012 to 2019 at the Verona University were retrieved from a prospectively maintained database. The patients submitted to RDP were divided into the dual-console platform group (DG) and compared to the standard robotic procedure group (SG).
    Results: In the study period, 102 robotic distal pancreatectomies were performed, of whom 42 patients (41%) belonged to the DG and 60 patients (59%) to the SG. Higher operation time was recorded in the DG compared to the SG (410 vs. 265 min, p < 0.001). The overall conversion rate of the series was 7% (n 7 patients). All the conversions were observed in the SG (p = 0.021). No differences in morbidity or pancreatic fistula rate were recorded (p > 0.05). No mortality events in the 90th postoperative days were reported in this series.
    Conclusions: The robotic dual-console approach for distal pancreatectomy is safe, feasible, and reproducible. The postoperative surgical outcomes are comparable to the standard RDP with the single-console da Vinci Surgical System®. This surgical technique can widely and safely improve the robotic surgical training program.

    Abstract Background: Postoperative fluid collections at the resection margin of the pancreatic stump are frequent after distal pancreatectomy, yet their clinical impact is unclear. The aim of this study was to assess the 30-day prevalence of postoperative fluid collections after distal pancreatectomy and the factors associated with a clinically relevant condition.
    Methods: Patients enrolled in a randomized controlled trial of parenchymal transection with either reinforced, triple-row staple, or ultrasonic dissector underwent routine magnetic resonance 30 days postoperatively. Postoperative fluid collection was defined as a cyst-like lesion of at least 1 cm at the pancreatic resection margin. Postoperative fluid collections requiring any therapy were defined as clinically relevant.
    Results: A total of 133 patients were analyzed; 69 were in the triple-row staple transection arm, and 64 were in the ultrasonic dissector transection arm. The overall 30-day prevalence of postoperative fluid collections was 68% (n = 90), without any significant difference between the two trial arms. Postoperative serum hyperamylasemia was more frequent in patients with postoperative fluid collections than those without (31% vs 7%, P = .001). Among the postoperative fluid collection population, an early postoperative pancreatic fistula (odds ratio 14.9, P = .002), post pancreatectomy acute pancreatitis (odds ratio 12.7, P = .036), and postoperative fluid collection size larger than 50 mm (odds ratio 6.6, P = .046) were independently associated with a clinically relevant postoperative fluid collection.
    Conclusion: Postoperative fluid collections at the resection margin are common after distal pancreatectomy and can be predicted by early assessment of postoperative serum hyperamylasemia. A preceding pancreatectomy acute pancreatitis and/or postoperative pancreatic fistula and large collections (>50 mm) were associated with a clinically relevant postoperative fluid collection, representing targets for closer follow-up or earlier therapeutic interventions.

    Abstract Objective: The incidence for clinically relevant postoperative pancreatic fistulas (CR-POPF) in distal pancreatectomy (DP) ranges up to 25%. None of the available sealants significantly reduce CR-POPF. A new biodegradable sealant patch was able to reduce POPF and to achieve bleeding control in a preclinical porcine DP model. The aim of this first-in-human study was to assess the safety and performance of the sealant patch.
    Methods: In this multicenter, single-arm study, 40 patients undergoing distal pancreatectomy were prospectively enrolled from 8 centers. Following surgical resection, the transection plane was closed according to the standard of care and manually covered with the sealant patch. As primary endpoint the incidence of CR-POPF up to 30-days postoperatively was evaluated. The secondary endpoints included the assessment of complications and device usability.
    Results: Among 40 patients after distal pancreatectomy, CR-POPF occurred in 7 (17.5%) up to postoperative day 30. No type C POPF was observed. There was no intraoperative bleeding observed after patch application.
    Conclusion: The results of this international phase II study demonstrate promising results of a new sealant patch regarding the rate of CR-POPF. Randomized studies are now needed to confirm the superiority of the current patch as compared to the best current practice.

    Abstract Background: High-grade neuroendocrine neoplasms (NENs) comprise both well-differentiated grade 3 neuroendocrine tumors (G3 NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) nearly always include poorly differentiated NEC as the neuroendocrine component. The efficacy and safety of frontline mFOLFIRINOX chemotherapy has never been investigated in patients with high-grade NENs.
    Patients and methods: We conducted a multi-institutional retrospective analysis of patients with advanced high-grade NEN of the gastroenteropancreatic tract or of unknown origin seen between February 2016 and April 2023 who received treatment with frontline mFOLFIRINOX.
    Results: A total of 35 patients were included (G3 NETs: n=2; NECs: n=25; MiNENs: n=8; stage III: n=5; stage IV: n=30). The objective response rate was 77% (complete response: 3%; partial response: 74%). Median progression-free survival was 12 months (95% CI, 9.2-16.2 months) and median overall survival was 20.6 months (95% CI, 17.2-30.6 months). No significant differences in efficacy were seen according to primary site, histopathology, and Ki-67 proliferative index. All 5 patients with stage III disease who received mFOLFIRINOX obtained an objective response and underwent radical surgery or definitive radiotherapy with curative intent, with a recurrence rate of 40%. Grade 3 or 4 adverse events were observed in 43% of patients (mainly neutropenia and diarrhea). Females were at significantly increased risk of developing severe toxicities.
    Conclusions: mFOLFIRINOX shows antitumor activity against high-grade NENs. Well-designed, prospective clinical trials are needed to assess the efficacy of mFOLFIRINOX in both the neoadjuvant and metastatic settings.

    Abstract Background: Intestinal neuroendocrine tumours (I-NETs) represent a non-negligible entity among intestinal neoplasms, with metastatic spreading usually present at the time of diagnosis. In this context, effective molecular actionable targets are still lacking. Through transcriptome analysis, we aim at refining the molecular taxonomy of I-NETs, also providing insights towards the identification of new therapeutic vulnerabilities.
    Materials and methods: A retrospective series of 38 primary sporadic, surgically-resected I-NETs were assessed for transcriptome profiling of 20,815 genes.
    Results: Transcriptome analysis detected 643 highly expressed genes. Unsupervised hierarchical clustering, differential expression analysis and gene set enriched analysis identified three different tumour clusters (CL): CL-A, CL-B, CL-C. CL-A showed the overexpression of ARGFX, BIRC8, NANOS2, and SSTR4 genes. Its most characterizing signatures were those related to cell-junctions, and activation of mTOR and WNT pathway. CL-A was also enriched in T CD8 + lymphocytes. CL-B showed the overexpression of PCSK1, QPCT, ST18, and TPH1 genes. Its most characterizing signatures were those related to adipogenesis, neuroendocrine metabolism, and splice site machinery-related processes. CL-B was also enriched in T CD4 + lymphocytes. CL-C showed the overexpression of ALB, ANG, ARG1, and HP genes. Its most characterizing signatures were complement/coagulation and xenobiotic metabolism. CL-C was also enriched in M1/2 macrophages. These CL-based differences may have therapeutic implications in refining the management of I-NET patients. At last, we described a specific gene-set for differentiating I-NET from pancreatic NET.
    Discussion: Our data represent an additional step for refining the molecular taxonomy of I-NET, identifying novel transcriptome subgroups with different biology and therapeutic opportunities.
