ABSTRACT: BACKGROUND: The oncological impact of surgical complications has been studied in visceral and pancreatic cancer. AIM: To investigate the impact of complications on tumour recurrence after resections for pancreatic neuroendocrine tumours. METHODS: We have retrospectively analysed 105 consecutive resections performed at the Royal Free London Hospital from 1998 to 2014, and studied the long-term outcome of nil-minor (<3) versus major (≥3) Clavien-Dindo complications (CD) on disease-free (DFS) and overall survival (OS). RESULTS: The series accounted for 41 (39%) pancreaticoduodenectomies, two (1.9%) central, 48 (45.7%) distal pancreatectomies, eight (7.6%) enucleations, four (3.8%) total pancreatectomies. Sixteen (15.2%) were extended to adjacent organs, 13 (12.3%) to minor liver resections. Postoperative complications presented in 43 (40.1%) patients; CD grade 1 or 2 in 23 (21.9%), grades ≥3 in 20 (19%). Among 25 (23.8%) pancreatic fistulas, 14 (13.3%) were grades B or C. Thirty-four (32.4%) patients developed exocrine, and 31 (29.5%) endocrine insufficiency. Seven patients died during a median 27 (0-175) months follow up. Thirty-day mortality was 0.9%. OS was 94.1% at 5 years. Thirty tumours recurred within 11.7 (0.8-141.5) months. DFS was 44% at 5 years. At univariate analysis, high-grade complications were not associated with shorter DFS (p = 0.744). At multivariate analysis, no parameter was independent predictor for DFS or OS. The comparison of nil-minor versus major complications showed no DFS difference (p = 0.253). CONCLUSION: From our series, major complications after P-NETs resection are not associated to different disease recurrence; hence do not require different follow up or adjuvant regimens.

2 Article Long-Term Outcomes of Surgical Management of Pancreatic Neuroendocrine Tumors with Synchronous Liver Metastases. 2015

Partelli, Stefano / Inama, Marco / Rinke, Anja / Begum, Nehara / Valente, Roberto / Fendrich, Volker / Tamburrino, Domenico / Keck, Tobias / Caplin, Martyn E / Bartsch, Detlef / Thirlwell, Christina / Fusai, Giuseppe / Falconi, Massimo. ·Pancreatic Surgery Unit, University Hospital of Ancona, Ancona, Italy. ·Neuroendocrinology · Pubmed #26043944.

ABSTRACT: BACKGROUND: The value of surgical resection in the management of pancreatic neuroendocrine tumors (PNET) with liver metastases (LM) is still debated. The aim of this study was to evaluate the outcomes of surgery of PNET with LM. METHODS: Patients with PNET with synchronous LM between 2000 and 2011 from 4 high-volume institutions were included. The patients were divided into 3 groups: curative resection, palliative resection, and no resection. RESULTS: Overall, 166 patients were included. Eighteen patients (11%) underwent curative resection, 73 patients (43%) underwent palliative resection, and 75 patients (46%) underwent conservative treatment. The median overall survival (OS) from the time of diagnosis was 73 months. Patients who underwent curative resection had a significantly better median OS from the initial diagnosis compared with those who underwent palliative resection and those who were conservatively treated (97 vs. 89 vs. 36 months, p = 0.0001). The median OS from the time of diagnosis in those patients who underwent radical or palliative resection was 97 months, with a 5-year survival rate of 76%. On multivariate analysis, factors associated with OS from the time of diagnosis were the presence of bilobar metastases, tumor grading, and curative resection in a first model. On a second model, curative or palliative surgery was an independent predictor of OS. Among 91 patients who underwent surgery, the presence of pancreatic neuroendocrine carcinoma G3 was the only factor independently associated with a poorer survival after surgery (median OS: 35 vs. 97 months, p < 0.0001). CONCLUSIONS: Patients with LM from PNET benefit from surgical resection, although surgery should be reserved to well- or moderately differentiated forms.

3 Article Poorly differentiated resectable pancreatic cancer: is upfront resection worthwhile? 2012

Crippa, Stefano / Partelli, Stefano / Zamboni, Giuseppe / Barugola, Giuliano / Capelli, Paola / Inama, Marco / Bassi, Claudio / Pederzoli, Paolo / Falconi, Massimo. ·Department of Surgery, University of Verona, Verona, Italy. ste.crippa@libero.it ·Surgery · Pubmed #22766365.

ABSTRACT: BACKGROUND: Poorly differentiated, resectable pancreatic ductal adenocarcinoma is associated with early recurrence and may benefit from neoadjuvant treatment. The aim of this study was to evaluate clinicopathologic characteristics and survival of patients with resectable pancreatic ductal adenocarcinoma according to histologic grading. METHODS: A total of 502 patients who underwent resection for pancreatic ductal adenocarcinoma between 1990 and 2008 were analyzed via the use of different histologic grading. RESULTS: Well-differentiated (G1), moderately differentiated (G2), and poorly differentiated (G3) pancreatic ductal adenocarcinomas were found in 23 (4.5%), 310 (62%), and 169 (33.5%) patients. Adjuvant therapy, N status, grading, and R status were independent predictors of disease-specific survival for the entire cohort, with 1- and 5-year disease-specific survival rates of 81% and 21%, respectively. Only the presence of symptoms was a significant clinical predictor of G3 status (P = .035). G3 neoplasms were characterized by a greater rate of lymph node metastases, microvascular/perineural invasion, and R2 resections. Median disease-specific survival was 77, 26, and 20 months for G1, G2, and G3 neoplasms (P < .0001). Median disease-free survival was 63, 14, and 9 months for G1, G2, and G3 pancreatic ductal adenocarcinoma (P < .0001). Adjuvant therapy improved disease-specific survival in G2 (P < .04) and G3 (P < .0001) pancreatic ductal adenocarcinoma, with a greater survival benefit for G3 neoplasms (hazard ratio: 1.334 vs 2.116). CONCLUSION: G3 pancreatic ductal adenocarcinoma is associated with a lesser rate of disease-free survival after resection and with the presence of other poor prognostic factors. The benefit of adjuvant therapy is greater in G3 than in G1 and G2 neoplasms. On the basis of these findings, patients with resectable G3 PDAC can be considered as possible targets for neoadjuvant treatment.

4 Article Perioperative and long-term results of laparoscopic spleen-preserving distal pancreatectomy with or without splenic vessels conservation: a retrospective analysis. 2012

Butturini, Giovanni / Inama, Marco / Malleo, Giuseppe / Manfredi, Riccardo / Melotti, Gian Luigi / Piccoli, Micaela / Perandini, Simone / Pederzoli, Paolo / Bassi, Claudio. ·Department of Surgery, University of Verona, Verona, Italy. giovanni.butturini@ospedaleuniverona.it ·J Surg Oncol · Pubmed #22025322.

ABSTRACT: BACKGROUND AND OBJECTIVES: Laparoscopic spleen-preserving distal pancreatectomy can be performed with or without splenic vessels conservation. The formation of perigastric varices is the main long-term complication and represents the area of major concern among surgeons. Aim of this paper was to evaluate the outcomes of patients who underwent spleen-preserving distal pancreatectomy (with or without splenic vessels conservation) at our institution. METHODS: Retrospective search of an electronic database from 1999 through 2007. Standard statistical methods were used. RESULTS: 43 individuals were analyzed. Postoperative morbidity was 56%. Patients managed by splenic vessels conservation were 36; in the remaining seven splenic vessels resection was performed. Pathologic details and the rate postoperative complications were not different between the two groups. Two splenectomies were necessary for postoperative splenic infarction (one in each group). 28 patients accepted the follow-up protocol. At 12 months, the rate of perigastric varices was 60.0% after splenic vessels resection and 21.7% after splenic vessels conservation (P = 0.123). No gastrointestinal bleeding occurred at a median follow-up of 69 months (37-139). CONCLUSION: Laparoscopic spleen-preserving distal pancreatectomy is feasible. A moderate risk of postoperative splenic infarction has to be taken into account, and the formation of perigastric varices may be interpreted as a paraphysiologic phenomenon, especially after splenic vessels resection.
