Clinicopathological factors associated with recurrence in patients undergoing resection of pancreatic solid pseudopapillary neoplasm. Discov Oncol 2021; 12:53. [PMID: 35201506 PMCID: PMC8777513 DOI: 10.1007/s12672-021-00451-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 11/17/2021] [Indexed: 11/06/2022] Open
Abstract
PURPOSE Solid pseudopapillary neoplasm (SPN) is an uncommon pathology with a low-grade malignancy. Surgery is the milestone treatment. Nevertheless, despite appropriate management, some patients present recurrence. Risk factors associated with recurrence are unclear. The objective was to identify the clinicopathological factors associated with recurrence in patients with SPN treated with pancreatic resection. METHODS Medical records of patients treated with pancreatic resection during 2006-2020 were evaluated. Patients with histological diagnosis of SPN were included. Survival analysis was performed to identify the clinicopathological factors related to recurrence. RESULTS Seventy-four patients were diagnosed with SPN; 70 (94.6%) patients were female, and the median age was 20 years old. The median tumor diameter was 7.9 cm. Multivisceral resection was performed in 9 (12.2%) patients. Four (5.4%) patients presented lymph node metastasis.R0 resection was achieved in all cases. Six (8%) patients presented recurrence and the liver was the most frequent recurrence site (n = 5).After a median follow-up of 40.2 months, 9 (12%) patients died. Five (6.8%) patients died of disease progression. The 1-3- and 5-year overall survival (OS) was 97.1%, 90.2% and 79.9%, respectively. The 1-3-and-5-year recurrence-free survival (RFS) was 98.4%, 89.9% and 87%, respectively. In the univariate Cox-regression analysis, age ≥ 28 years(HR = 8.61, 95% CI 1.1-73.8),tumor diameter ≥ 10 cm(HR = 9.3, 95% CI 1.12-79.6),invasion of adjacent organs (HR = 7.45, 95% CI 1.5-36.9), lymph node metastasis (pN +) (HR = 16.8, 95% CI 2.96-94.9) and, AJCC Stage III (HR = 10.1, 95% CI 1.2-90.9) were identified as predictors for recurrence. CONCLUSIONS SPN is more frequently diagnosed in young women with a good overall prognosis after an R0 surgical resection even with disease recurrence. Age ≥ 28 years, larger tumors ≥ 10 cm, invasion of adjacent organs, lymph node metastasis(pN +) and, AJCC Stage III were predictors factors of recurrence in resected SPN.

Abstract
PURPOSE Pancreas tumors are extremely rare in pediatric and adolescent patients. Surgical resection is the mainstay of treatment; however, the data are limited with respect to morbidity and mortality. We aimed to evaluate short- and long-term outcomes of pediatric and adolescent patients who underwent surgical resection of pancreatic tumors. METHODS Patients [Formula: see text] 18-year-olds who underwent resection of pancreas tumor at the National Institute of Neoplastic Diseases INEN during 2000-2020 were included. RESULTS Thirty-four patients were diagnosed; 28 patients were female and 6 were male. The median age was 13.4-years-old. Histological diagnosis was solid pseudopapillary neoplasm (SPN) (n = 29, 85.3%), pancreatoblastoma (n = 3), neuroendocrine carcinoma (n = 1), and insulinoma (n = 1). No patient experienced postoperative mortality and 15 (44.1%) patients developed postoperative complications including pancreatic fistula as the most frequent. Under a median follow-up period of 33.8 (0.5-138) months, four (11.8%) patients died. Of the 29 patients with SPN, the 3- and-5-year OS rates were 100% and 83.1%, respectively. CONCLUSIONS SPN was the most frequent cause of surgical treatment for pediatric and adolescent patients in the high-volume cancer center in Peru and was associated with favorable survival. Pancreaticoduodenectomy was safely performed in this patient group with acceptable morbidity and zero mortality.

Abstract
Background The treatment of high-grade (III/IV/V) blunt pancreatic injuries remains controversial. The study aims to summarize and evaluate nonresection management of the pancreas for grade III and IV blunt pancreatic injuries in children. Methods Twenty children [6.9 (3–12) years] treated at our center between January 2010 and June 2018 were included in this study. Their medical records and the outpatient follow-up data within 12 weeks after discharge were retrospectively reviewed. Long-term follow-up was conducted by telephone in February 2020. Results Nine children developed complications, including 8 pancreatic pseudocysts and 1 abdominal infection, after treatment at external hospitals and were transferred to our center with an average length of stay of 33.8 (8–63) days. Eleven children were admitted to our hospital directly after injury, with an average length of stay of 47.5 (23–69) days. One child underwent emergency laparotomy for hemorrhagic shock and Roux-en-Y drainage of the distal pancreas. The remaining 10 children received conservative treatment: 7 developed pancreatic pseudocysts, 2 developed abdominal infections, and 1 recovered uneventfully. For children with pancreatic pseudocysts (15/20, 75.0%), 4 recovered after conservative treatment, 4 recovered after percutaneous puncture, 5 recovered after external drainage of the cyst, and 2 recovered after alimentary tract anastomosis. Three children (3/20, 15.0%) who developed abdominal infection recovered after abdominal irrigation and drainage. No child was admitted to the ICU or died. Four children (4/20, 20.0%) developed local pancreatic atrophy within 12 weeks after discharge, but no other long-term complications were observed. Conclusions Nonresection management of the pancreas could be a feasible option for children with grade III and IV blunt pancreatic injuries. Regular long-term follow-up is essential in terms of pancreatic function, especially in patients with pancreatic atrophy.

Abstract
PURPOSE Pancreatic tumors are rare in children and limited data are available regarding incidence, treatment, and outcomes. We aim to describe patient and tumor characteristics and to report on survival of these diseases. METHODS Children with pancreatic tumors were queried from the National Cancer Database (2004-2014). The association between treatment and hazard of death was assessed using Kaplan-Meier method and Cox regression model. RESULTS We identified 109 children with pancreatic tumors; 52% were male and median age at diagnosis was 14 years. Tumors were distributed as follows: pseudopapillary neoplasm (30%), endocrine tumors (27%), pancreatoblastoma (16%), pancreatic adenocarcinoma (16%), sarcoma (6%) and neuroblastoma (5%). Seventy-nine patients underwent surgery, of which 76% achieved R0 resection. Most patients (85%) had lymph nodes examined, of which 22% had positive nodes. Five-year overall survival by tumor histology was 95% (pseudopapillary neoplasm), 75% (neuroblastoma), 70% (pancreatoblastoma), 51% (endocrine tumors), 43% (sarcoma), and 34% (adenocarcinoma). On multivariable analysis, surgical resection was the strongest predictor of survival (HR 0.26, 95% CI 0.10-0.68, p < 0.01). CONCLUSION Overall survival of children with pancreatic tumors is grim, with varying survival rates among different tumors. Surgical resection is associated with improved long-term survival.

Abstract
Neuroendocrine cells are dispersed diffusely throughout many organ systems in the body and hence neuroendocrine tumors (NETs) can arise from almost anywhere in the body. NETs are considered rare tumors, and the current incidence is reported to be about 6 cases in 100 000 in adults and about 2.8 cases per million in the pediatric age group. Despite the indolent nature of these tumors, they have the potential for metastasis and significant morbidity. NETs can be asymptomatic at the time of diagnosis or can present with flushing, diarrhea, wheezing, weight loss, and fatigue among other symptoms. Due to the ambiguity of presenting symptoms, it is not uncommon for NETs to be diagnosed late in the disease course. Despite low incidence, the prevalence of the disease is high since patients live for many years and sometimes decades. Early detection of well-differentiated NETs has excellent outcomes with the majority of early-stage diseases being cured with surgical resection alone. There have been recent advancements in the management of metastatic progressive NETs with approval of peptide receptor radionuclide therapy, telotristat, and everolimus. Awareness of these rare tumors and its management is crucial for optimal management. This article will focus on pediatric NETs and current advances in its management.

Abstract
AIM OF STUDY Duodenum-preserving resection of the pancreatic head (DPRPH) with Roux-en-Y pancreatojejunostomy is a procedure used to remove focal pathological lesions of the pancreatic head. Although predominantly used in adult patients, it is both safe and effective in children. The aim of this study was to review our experience with this procedure, with focus on its indications, complications and long-term outcomes. METHODS A retrospective analysis of pediatric patients who underwent DPRPH between 1994 and 2015 was performed. Patient files were reviewed for demographic, diagnostic, operative and histological details, postoperative complications. Patients were contacted telephonically and sent questionnaires to determine long-term outcomes. RESULTS The study cohort consists of 21 patients, 14 girls and 7 boys, with an average age of 11.72 years (range 3 months to 18.6 years), who underwent DPRPH with end-to-end anastomosis of the jejunum to the pancreatic body (Roux-en-Y anastomosis). In four cases the head and also part of the body of the pancreas was resected. In the remaining 17 cases, only the head of the pancreas was resected. Indications for DPRPH were solid pseudopapillary tumor of the pancreas (n = 10), trauma (n = 8), pancreas divisum (n = 1), focal congenital hyperinsulinism (n = 1) and pancreatic cyst (n = 1). The length of follow-up ranged from 1 to 22 years (average 9.66). One patient developed a biliary fistula, which closed spontaneously within 2 weeks after stent insertion. A recurrence of abdominal pain was reported in two patients, occurring at 7 months after the operation in one patient and at 1 year in the other. Pancreatic endocrine insufficiency did not occur in any of the 21 patients. Seven patients currently require a low fat diet, five of which need pancreatic enzyme supplementation. An additional two patients need enzyme supplementation without dietary restriction. CONCLUSION DPRPH is a safe and effective procedure for the treatment of large focal pathological lesions of the pancreatic head in children. As a less invasive procedure than pancreatoduodenectomy, it is more appropriate for the developing child.

Abstract
A systematic review of 32 studies reporting on 489 children with pancreatic tumors was performed. The most prevalent histologic subtype was solid pseudopapillary tumor (SPT) (61.3%). Pancreaticoduodenectomy was the most commonly performed operation (48%). Neoadjuvant chemo/radiotherapy was utilized in 3.9, 36.2, 25, and 27.8% of patients with SPTs, pancreatoblastomas (PBLs), neuroendocrine tumors, and exocrine carcinomas, respectively. Adjuvant chemotherapy (75.6%) and radiation (34%) were most commonly utilized in PBLs. All-cause mortality was highest in exocrine carcinomas (50%). Overall, 98.8% of patients with SPTs survived. PBL exhibited the highest recurrence rate (14.7%) within a mean of 23.5 months.

Abstract
PURPOSE To examine the clinicopathological characteristics and prognosis of pediatric patients with malignant pancreatic tumors in a population-based cohort. METHODS The Surveillance, Epidemiology, and End Results (SEER) database was utilized to identify all pediatric patients with malignant pancreatic tumors, diagnosed between 1973 and 2013. Kaplan-Meier analysis was performed to determine median and five-year overall survival (OS) rates. Univariate survival analysis was executed using the log-rank test. Cox proportional hazards model was used to identify variables independently associated with mortality. RESULTS A total of 114 patients with pancreatic malignancies were identified. Median patient age was 16years and the majority of patients were white (64%) females (61.4%). The most prevalent histologic subtype was neuroendocrine tumors (35.1%), whereas pancreatoblastoma was more common during the first decade of life (P<0.001). Distant metastases were noted in 41.7% of the patients, while 33.3% and 25% had localized and regional disease respectively. Five-year OS rates were 77%, 66.4% and 64.8% for patients with pancreatoblastoma, neuroendocrine and epithelial tumors respectively. No death was observed in the solid pseudopapillary tumor group. Only history of having cancer-directed surgery (CDS) was significantly associated with lower overall mortality (HR: 5.1, 95% CI: 2.1, 12.4). CONCLUSION Pancreatic malignancies are rare in children. Their prognosis is variable and only CDS was independently associated with superior survival. EVIDENCE RATING/CLASSIFICATION Prognosis study, Level II.

Prognostic significance of cytokeratin 19 expression in pancreatic neuroendocrine tumor: A meta-analysis. PLoS One 2017; 12:e0187588. [PMID: 29136022 PMCID: PMC5685577 DOI: 10.1371/journal.pone.0187588] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Accepted: 10/23/2017] [Indexed: 01/11/2023] Open
Abstract
Background Pancreatic neuroendocrine tumor (PNET) comprises 1–2% of all pancreatic tumors, but its incidence is increasing. Although many studies have investigated the correlation between cytokeratin 19 (CK-19) and PNET, the prognostic significance of CK-19 expression in PNET is inconclusive. Methods Eligible studies were retrieved from Pubmed, Elsevier, Embase, Cochrane Library and Web of Science databases. All relevant data were extracted to analyze the relationship between CK-19 and PNET. We utilized a fixed or random effects model to calculate the pooled odds ratio (OR) with 95% confidence intervals (CI). Results Pooled data indicated CK-19 expression was significantly associated with poor 3- and 5-year overall survival (OS) for PNET, but not for 1-year overall survival. Additionally, positive CK-19 expression was correlated with large tumor size, advanced differentiation grade in World Health Organization-2010 (WHO-2010) and WHO-2004, vascular invasion, lymph node metastasis and liver metastasis. Conclusions Positive CK-19 expression can be used as a predictor of poor prognosis of PNET.

Abstract
The aim of this study was to compare operative versus nonoperative management of blunt pancreatic trauma in children. A systematic literature search was performed. Studies including children with blunt pancreatic injuries classified according to the American Association for the Surgery of Trauma classification were included. The primary outcome was pseudocyst formation. After screening 526 studies, 23 studies with 928 patients were included. Sufficient data were available for 674 patients (73%). Of 309 patients with grade I or II injuries, 258 (83%) were initially managed nonoperatively with a 96% success rate. Of 365 patients with grade III, IV, or V injuries, nonoperative management was initially chosen for 167 patients (46%) with an 89% success rate. Pseudocysts occurred in 18% of patients managed nonoperatively versus 4% of patients managed operatively (P < 0.01), of whom 65% were treated nonoperatively. Hospitalization was 20.5 days after nonoperative versus 15.1 days after operative management (nonparametric t test, P = 0.41). Blunt pancreatic trauma in children can be managed nonoperatively in the majority of patients with grade I or II injuries and in about half of the patients with grade III to V injuries. Although pseudocysts are more common after nonoperative management, two thirds can be managed nonoperatively.

Abstract
Pancreatic tumors rarely occur in adolescents, and the appropriateness of radical resection for these patients remains controversial.Medical records were retrospectively reviewed for patients younger than 19 years who underwent radical resection or limited resection (enucleation) between 2000 and 2015. Patient demographics, clinical characteristics, operative details, growth, and survival were analyzed.During the study period, 11 adolescents (mean age, 16.18 years; standard deviation, 1.99; interquartile range, 15.0-18.0) underwent radical resection (n = 7) or enucleation (n = 4) to treat solid pseudopapillary tumors (n = 5), pancreatic neuroendocrine tumors (n = 5), or pancreatic ductal adenocarcinoma (n = 1). None of the 7 patients who underwent radical resection experienced recurrence or serious complications, while 3 of 4 patients who underwent enucleation experienced recurrence (P = 0.02). Recurrence-free survival was slightly longer in patients who underwent radical resection, and this procedure did not appear to affect adolescent growth and development.Radical resection might be safe and effective for adolescents with pancreatic tumors.

Abstract
Pancreatic neuroendocrine tumors are a rare group of neoplasms that arise from multipotent stem cells in the pancreatic ductal epithelium. Although they comprise only 1% to 2% of pancreatic neoplasms, their incidence is increasing. Most pancreatic neuroendocrine tumors are nonfunctioning, but they can secrete various hormones resulting in unique clinical syndromes. Clinicians must be aware of the diverse manifestations of this disease, as the key step to management of these rare tumors is to first suspect the diagnosis.

Abstract
INTRODUCTION Metastasized pancreatic neuroendocrine tumors are extremely rare malignancies, especially in children. Therefore, therapeutic options are limited, and few standardized therapy regimens exist. CASE PRESENTATION We report a case of a 14-year-old white girl. In 2011 she was diagnosed with a metastasized, well-differentiated pancreatic neuroendocrine tumor with expression of synaptophysin and chromogranin A. We describe her clinical course with special attention to her individual therapeutic regimens while bringing together several disciplines of medicine. CONCLUSIONS In patients such as ours, surgical intervention may be the only therapy that will lead to long-term survival.

Solid pseudopapillary neoplasm of the pancreas in children: a 15-year experience and the identification of a unique immunohistochemical marker. J Pediatr Surg 2013; 48:2054-60.

Abstract
PURPOSE To review our 15-year experience in the management of children with solid pseudopapillary neoplasm (SPPN) of the pancreas at a single pediatric institution, to delineate a unique immunohistochemical marker for SPPN, and to analyze cumulative data on this rare entity in the literature. METHODS We did a retrospective analysis of the demographic data, clinical presentation, immunohistochemical characteristics, surgical approach, and long-term outcomes of all patients diagnosed with SPPN between 1997 and 2012. RESULTS There were 6 patients in the series, 5 females and 1 male. Median age at presentation and at surgery was 15 years (11-18 years). Abdominal pain was the presenting symptom in 5 cases and jaundice in 1 case. Two patients had a pancreatic head tumor and underwent a pylorus-preserving pancreaticoduodenectomy. Two patients had the tumor in the pancreatic tail and underwent a distal pancreatectomy with splenectomy. Two patients had the tumor in the pancreatic body and underwent a distal pancreatectomy with splenectomy in one case and with preservation of the spleen in the other. All tumors were completely resected with pathologic margins free of disease. The median maximum diameter was 6.8 cm (3 to 15 cm). On immunohistochemistry the tumors exhibited different combinations of non-specific markers like chromogranin, vimentin and neuron-specific enolase, but all tumors showed the highly SPPN-specific paranuclear dot-like immunoreactivity pattern for CD99 in the solid as well as in the pseudopapillary areas. No patient had metastasis at presentation. Median follow-up was 6.5 years (6 months to 15 years). There were no recurrences, no long-term metastasis, and all patients are disease-free. CONCLUSION Our series supports the concept that complete resection is necessary to achieve the best possible long-term results. Additionally, we demonstrate that SPPN exhibits a very unique immunostaining pattern for CD99 that is present in all cases.

Abstract
Lymphoepithelial cyst (LEC) of the pancreas is almost always reported as a case report or in small series mostly in male adult patients with vague clinical manifestations and difficult pre-operative diagnosis. Between the years 2007 and 2012, two female children with LEC of the pancreas were operated on at the Children's Surgical Unit of Murtala Mohammad Specialist Hospital, Kano in northern Nigeria. Satisfactory outcomes were achieved after distal pancreatectomy and splenectomy in one and a Whipple procedure in the other. This benign lesion of the pancreas should be considered in the differential diagnosis of cystic lesions of the pancreas in children.
