Critical appraisal of the adequacy of surgical indications for non-functioning pancreatic neuroendocrine tumours. BJS Open 2024; 8:zrae083. [PMID: 39107074 PMCID: PMC11303005 DOI: 10.1093/bjsopen/zrae083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 04/22/2024] [Accepted: 06/20/2024] [Indexed: 08/09/2024] Open
Abstract
BACKGROUND The lack of preoperative prognostic factors to accurately predict tumour aggressiveness in non-functioning pancreatic neuroendocrine tumours may result in inappropriate management decisions. This study aimed to critically evaluate the adequacy of surgical treatment in patients with resectable non-functioning pancreatic neuroendocrine tumours and investigate preoperative features of surgical appropriateness. METHODS A retrospective study was conducted on patients who underwent curative surgery for non-functioning pancreatic neuroendocrine tumours at San Raffaele Hospital (2002-2022). The appropriateness of surgical treatment was categorized as appropriate, potential overtreatment and potential undertreatment based on histologic features of aggressiveness and disease relapse within 1 year from surgery (early relapse). RESULTS A total of 384 patients were included. Among them, 230 (60%) received appropriate surgical treatment, whereas the remaining 154 (40%) underwent potentially inadequate treatment: 129 (34%) experienced potential overtreatment and 25 (6%) received potential undertreatment. The appropriateness of surgical treatment was significantly associated with radiological tumour size (P < 0.001), tumour site (P = 0.012), surgical technique (P < 0.001) and year of surgical resection (P < 0.001). Surgery performed before 2015 (OR 2.580, 95% c.i. 1.570 to 4.242; P < 0.001), radiological tumour diameter < 25.5 mm (OR 6.566, 95% c.i. 4.010 to 10.751; P < 0.001) and pancreatic body/tail localization (OR 1.908, 95% c.i. 1.119 to 3.253; P = 0.018) were identified as independent predictors of potential overtreatment. Radiological tumour size was the only independent determinant of potential undertreatment (OR 0.291, 95% c.i. 0.107 to 0.791; P = 0.016). Patients subjected to potential undertreatment exhibited significantly poorer disease-free survival (P < 0.001), overall survival (P < 0.001) and disease-specific survival (P < 0.001). CONCLUSIONS Potential overtreatment occurs in nearly one-third of patients undergoing surgery for non-functioning pancreatic neuroendocrine tumours. Tumour diameter emerges as the sole variable capable of predicting the risk of both potential surgical overtreatment and undertreatment.

J Gastrointest Surg 2023; 27:2611-2627. [PMID: 37670106 PMCID: PMC10661729 DOI: 10.1007/s11605-023-05789-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Accepted: 07/08/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Pancreatic benign, cystic, and neuroendocrine neoplasms are increasingly detected and recommended for surgical treatment. In multiorgan resection pancreatoduodenectomy or parenchyma-sparing, local extirpation is a challenge for decision-making regarding surgery-related early and late postoperative morbidity. METHODS PubMed, Embase, and Cochrane Libraries were searched for studies reporting early surgery-related complications following pancreatoduodenectomy (PD) and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. Thirty-four cohort studies comprising data from 1099 patients were analyzed. In total, 654 patients underwent DPPHR and 445 patients PD for benign tumors. This review and meta-analysis does not need ethical approval. RESULTS Comparing DPPHRt and PD, the need for blood transfusion (OR 0.20, 95% CI 0.10-0.41, p<0.01), re-intervention for serious surgery-related complications (OR 0.48, 95% CI 0.31-0.73, p<0.001), and re-operation for severe complications (OR 0.50, 95% CI 0.26-0.95, p=0.04) were significantly less frequent following DPPHRt. Pancreatic fistula B+C (19.0 to 15.3%, p=0.99) and biliary fistula (6.3 to 4.3%; p=0.33) were in the same range following PD and DPPHRt. In-hospital mortality after DPPHRt was one of 350 patients (0.28%) and after PD eight of 445 patients (1.79%) (OR 0.32, 95% CI 0.10-1.09, p=0.07). Following DPPHRp, there was no mortality among the 192 patients. CONCLUSION DPPHR for benign pancreatic tumors is associated with significantly fewer surgery-related, serious, and severe postoperative complications and lower in-hospital mortality compared to PD. Tailored use of DPPHRt or DPPHRp contributes to a reduction of surgery-related complications. DPPHR has the potential to replace PD for benign tumors and premalignant cystic and neuroendocrine neoplasms of the pancreatic head.

Pancreatic resections for benign intraductal papillary mucinous neoplasms: Collateral damages from friendly fire. Surgery 2022; 172:1202-1209. [PMID: 35667898 DOI: 10.1016/j.surg.2022.04.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 04/05/2022] [Accepted: 04/28/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Surgical resection of intraductal papillary mucinous neoplasms is based on preoperative high-risk stigmata/worrisome features, but the risk of overtreatment remains high. The aim of this study was to evaluate surgical indications and perioperative and long-term complications in patients with low-grade intraductal papillary mucinous neoplasms. METHODS Patients who underwent surgical resection between 2009 and 2018 with a final histology of low-grade intraductal papillary mucinous neoplasms were included. Surgical indications, type of surgery, and short- and long-term outcomes were evaluated. RESULTS A significant decrease in the rate of patients resected for low-grade intraductal papillary mucinous neoplasms was observed (43.6% in 2009-2012 vs 27.8% in 2013-2018; P = .003), and 133 patients were finally included (62 women, median age: 68 years). Of these, 24.1% had 1 worrisome feature, 39.8% had ≥2 worrisome features, 18.8% had ≥1 high-risk stigmata, and 15.8% had ≥1 worrisome features + 1 high-risk stigmata. Overall surgical morbidity was 55.6%, 15.8% had Clavien-Dindo ≥3 complications, reoperation rate was 3.8%, and 90-day postoperative mortality was 1.5%. After a median follow-up of 60 months, 13 patients (11.5%) had a recurrence of benign intraductal papillary mucinous neoplasm in the pancreatic remnant, and 2 patients (1.8%) developed pancreatic ductal adenocarcinoma. After partial pancreatectomy, 51.3% of patients were taking pancreatic enzyme replacement therapy. Among nondiabetics, 26% developed diabetes after partial pancreatectomy, of which 38% were insulin-dependent. Eighteen patients (13.7%) developed incisional hernia. CONCLUSION Given the rates of morbidity and long-term complications after pancreatic resections, surgeons should attentively balance the true risks of intraductal papillary mucinous neoplasm degeneration with the risks of surgical resection in each patient.

Abstract
Changes in the exocrine function of the pancreas often develops after proximal and distal resections. Exocrine pancreatic insufficiency (EPI) is characterized by a reduced secretion of pancreatic enzymes, because of which the digestion and absorption of nutrients is impaired. Clinical manifestations of EPI and, as a consequence, changes in nutritional status significantly affect the quality of life of patients.

Abstract
Parenchymal sparing duodenal and pancreatic resection are safe procedures in selected patients with the aim to reduce endocrine and exocrine long-term dysfunction. When the tumor is benign or borderline malignant, this appears to be a good option for the surgeon, associated with low rates of severe surgery-related early postoperative complications and low in-hospital mortality. This mini review offers comments, tips and tricks, and a review of literature concerning those different options with specific illustrations in order to clarify their indication.

Abstract
The incidence gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) has dramatically risen over the last three decades, probably due to the increased detection of asymptomatic lesions. The diagnostic work-up for patients with suspected GEP-NENs is based on conventional imaging, endoscopy, pathology, and functional imaging, including 68Gallium-DOTATATE PET and 18F-FDG PET. The choice of the best treatment strategy should be based on the evaluation of tumor-related features and patient's characteristics. A conservative management, consisting of active surveillance or endoscopic resection, has been advocated for patients with small, incidentally discovered, nonfunctioning tumors without features of aggressiveness. On the other hand, surgery with lymphadenectomy, also with a minimally invasive approach, represents the gold standard for the curative treatment of localized disease. Moreover, surgical resection plays an important role also in the context of a multimodal treatment strategy for patients with advanced GEP-NENs. Finally, a wide range of medical therapies, comprising somatostatin analogues, peptide receptor radionuclide therapy, target therapies and several chemotherapy regimens, can be offered to patients with advanced GEP-NENs not amenable of surgical resection, according to the biological and molecular features of their disease.

Abstract
Background Small nonfunctional pancreatic neuroendocrine tumors (NF-PNETs) ≤2 cm have variable biological features, and there is no gold standard treatment for their management. The present study aimed to evaluate the risk of malignancy of small NF-PNETs and their outcomes following curative resection. Methods Patients with NF-PNETs undergoing surgical resection at the First Affiliated Hospital, College of Medicine, Zhejiang University, between 2012 and 2017 were included. Clinicopathological characteristics, perioperative results, and prognosis were retrospectively analyzed. Results A total of 73 patients were identified, including 28 with small NF-PNETs and 45 large PNETs; 32.1% of NF-PNETs ≤2 cm underwent a parenchyma-sparing pancreas surgery, which was >6.7% in large NF-PNETs. No statistically significant differences in perioperative results, postoperative complications, and long-term outcomes were found between small tumors undergoing standard and parenchyma-sparing pancreatectomy. Eighteen small tumors (64.3%) developed a perioperative complication, with a clinically significant pancreatic fistula rate of 25%; however, only 2 patient needed reintervention. Small NF-PNETs in 3 patients were malignant. Multivariate logistic regression showed that grade ≥3 and lymphovascular invasion were independently related to malignancy in NF-PNETs. Conclusions Small NF-PNETs (≤2 cm) are not immune from potential malignancy. Surgical resection may be considered for small tumors and can provide favorable postoperative and long-term outcomes. Parenchyma-sparing pancreatectomy may be an alternative surgery for selected small local NF-PNETs.

Abstract
Diarrhea is a recurrent symptom in patients with neuroendocrine tumors (NETs) and can represent different etiologies; thus, differential diagnosis is challenging. This paper distinguishes the different causes of chronic diarrhea in patients with gastroenteropancreatic NETs, with the aim to identify the most appropriate therapeutic approach. Underlying causes of diarrhea can be multifactorial, including not only diarrhea that is related to specific hormonal hypersecretory syndromes, but also diarrhea that is secondary to the following: extensive surgery which can cause pancreatic exocrine insufficiency or short bowel syndrome, treatment with somatostatin analogs or other antineoplastic agents, and bile acid malabsorption. After initial management of diarrhea with general treatments (dietary modification, use of antidiarrheals), a proper differential diagnosis is necessary to treat patients with specific etiology-driven therapeutic approaches, such as somatostatin analogs, pancreatic enzyme replacement therapy, and tryptophan hydroxylase inhibitors. In conclusion, NETs should be considered in the differential diagnosis of patients suffering from chronic diarrhea, after the exclusion of more common etiologies. Furthermore, physicians should keep in mind that several different etiologies might be responsible for diarrhea occurrence in NET patients. A prompt diagnosis of the actual cause of diarrhea is necessary to guide the treatment and a multidisciplinary approach is mandatory.

Abstract
OPINION STATEMENT Pancreatic neuroendocrine neoplasms (PanNENs) are increasingly recognized entities, whose incidence has dramatically grown during the last two decades. Surgery plays a pivotal role in their management as it represents the only chance of cure. Since PanNENs display a wide range of aggressiveness, their surgical management needs to be tailored on tumor's and patient's characteristics. Currently, there are several open questions and burning issues in the field of PanNEN, such as the management of asymptomatic nonfunctioning pancreatic neuroendocrine tumors (NF-PanNET) ≤ 2 cm. An active surveillance of these small lesions has been demonstrated to be safe although the available evidences are only based on retrospective studies. On the other hand, formal pancreatic resection associated with lymphadenectomy represents the gold standard for patients with localized NF-PanNEN > 2 cm or NF-PanNEN ≤ 2 cm in the presence of symptoms, dilation of the main pancreatic duct or suspicion of nodal metastases. Surgery plays also an important role in the setting of metastatic disease. In particular, surgery is generally recommended in the presence of low-grade, resectable, metastatic disease, but several series have reported also a survival benefit of palliative primary tumor resection in patients with unresectable liver metastases. The role of surgery in PanNEN G3 is still controversial. Indeed, surgery is associated with an improved survival in patients with well-differentiated PanNET G3, whereas there is almost no survival benefit in case of poorly differentiated lesions.
