Abstract
Background Hepatoid carcinoma (HC) is an extra-hepatic neoplasm that shares the morphological and immunohistochemical features of hepatocellular carcinoma. Pancreatic HC exists as either pure or combined type. Pure pancreatic HC is extremely rare, with only a few cases reported in the literature to date. Because of the rarity of pure pancreatic HC, its clinical features including incidence, behavior, and prognosis remain unclear. We herein report the case of a 56-year-old man who developed pure pancreatic HC treated with surgical resection. We also include a review of the existing literature. Case presentation A 56-year-old male patient was admitted to our hospital after a pancreatic cyst was identified by abdominal ultrasonography on a comprehensive medical examination. Endoscopic ultrasound revealed a cystic mass measuring 13 mm in size in the pancreatic head and a low-density mass measuring 16 mm in size in the pancreatic tail, which was partially enhanced on contrast-enhanced ultrasound. Contrast-enhanced computed tomography (CT) revealed a branch duct type intraductal papillary mucinous neoplasm in the pancreatic head and an early enhanced nodule measuring approximately 10 mm in size in the pancreatic tail. Endoscopic ultrasound-guided fine-needle aspiration of the hypervascular tumor was performed. The hypervascular tumor was suspected to be a solid pseudopapillary neoplasm. Laparoscopic spleen-preserving distal pancreatectomy was performed. Histology was identical to hepatocellular carcinoma of the liver. Immunohistochemically, the tumor cells were positive for hepatocyte paraffin 1, and a canalicular pattern was confirmed on the polyclonal carcinoembryonic antigen staining. The patient was diagnosed with a moderately differentiated pancreatic HC. The patient was followed up without adjuvant chemotherapy, and there was no evidence of recurrence at 6 months post-operatively. Conclusions We present a case of moderately differentiated pure pancreatic HC. For the accurate preoperative diagnosis of pure pancreatic HC, biopsy is preferred to cytology or preoperative imaging studies such as CT. The prognosis of pure pancreatic HC depends on its differentiation.

Abstract
Background Solid-pseudo papillary neoplasms of pancreas (SPNP) are rare in men and are often misdiagnosed. This study aimed to analyze the clinical and multi-slice computer tomography (MSCT) features of patients with SPNP, and examine the differences between males and females. Methods In this retrospective cohort study, the clinical and imaging data of 29 patients with histolopathologically confirmed SPNP (seven males and 22 females) that underwent radical resection, and underwent preoperative MSCT at the First People’s Hospital of Lianyungang between August 2010 and December 2018 were collected. All MSCT images were reviewed by two radiologists; disagreements were ruled by a third one. Results The median age of the 29 patients with SPNP was 30 (range, 12–70) years. The male patients were older than the female patients [median, 56 (28–66) vs. 29 (12–70), P = 0.012]. The median tumor size was 3.9 (range, 2.0–6.4) cm in the male SPNP patients, which was significantly lower than the 7.0 (range, 4.6–14.6) cm in the female patients (P < 0.001). The calcification rate of the SPNP was significantly higher in male than in female patients (P = 0.013). The percentage of solid tumor was higher in males than in females (P = 0.036). Capsule, bleeding, and enhancement in the arterial and venous phases were not significantly different between the male and female patients (all P > 0.05). Conclusion The imaging features of male SPNP are distinct from those of female patients. In males with pancreatic lesions, MSCT generally shows relatively small lesions with higher percentages of solid components and calcification, with typical enhancement suggesting SPNP.

Abstract
INTRODUCTION Solid pseudopapillary tumors (SPT) account for 1% to 3% of all pancreatic tumors. They have low malignant potential with a favorable prognosis, and predominantly occur in young women. The pathogenesis and clinical behavior of SPT are still uncertain. In addition, most ruptures of SPT were associated with blunt abdominal trauma, while spontaneous ruptures seemed to be quite rare. Up to now, there have been only 3 spontaneous ruptured SPT cases reported worldwide. PATIENT CONCERNS Here, we reported a 22-year-old female patient with left lower abdominal pain. Computed tomography (CT) showed that a hemorrhagic complex solid cystic mass located in the lesser omentum sac. DIAGNOSIS According to pathological findings of tumor specimen, the diagnosis of solid pseudopapillary tumor (SPT) of the pancreas was made. INTERVENTIONS Distal pancreatectomy and splenectomy was carried out. OUTCOMES The patient recovered to normal status within 10 days after surgery. CONCLUSION Besides, we reviewed about 50 cases in literatures to find out the clinical characteristics and differential diagnostic strategies of SPT.

Abstract
Pancreatic cystic neoplasms (PCN) are a heterogeneous group of pancreatic cysts that include intraductal papillary mucinous neoplasms, mucinous cystic neoplasms, serous cystic neoplasms and other rare cystic lesions, all with different biological behaviours and variable risk of progression to malignancy. As more pancreatic cysts are incidentally discovered on routine cross-sectional imaging, optimal surveillance for patients with PCN is becoming an increasingly common clinical problem, highlighting the need to balance cancer prevention with the risk of (surgical) overtreatment. This Review summarizes the latest developments in the diagnosis and management of PCN, including the quality of available evidence. Also discussed are the most important differences between the PCN guidelines from the American Gastroenterological Association, the International Association of Pancreatology and the European Study Group on Cystic Tumours of the Pancreas, including diagnostic and follow-up strategies and indications for surgery. Finally, new developments in the management of patients with PCN are addressed.

Abstract
CONTEXT.— Pancreatic cystic lesions (PCLs) are very common, and their detection is increasing with the advances in imaging techniques. Because of the major implications for management, distinguishing between neoplastic and nonneoplastic PCLs is critical. Neoplastic cysts with potential to progress into cancer include mucinous PCLs (intraductal papillary mucinous neoplasms and mucinous cystic neoplasms) and nonmucinous cysts (solid pseudopapillary tumors, serous cystic neoplasms, and neuroendocrine tumors with cystic degeneration). Nonneoplastic cysts with no risk of malignant transformation include pseudocysts, retention cysts, lymphoepithelial cysts, cystic pancreatic lymphangioma, and duplication cyst/ciliated foregut cysts. The role of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) cytology with cyst fluid analysis in the diagnosis of PCLs has evolved during the last decade; however, a definitive diagnosis on cytologic specimens is hampered by the sparse cellularity and can be challenging. EUS-FNA can play an important role to differentiate low-risk from high-risk pancreatic cysts and to distinguish between patients with cysts who need clinical follow-up versus those who require surgery. OBJECTIVE.— To provide an integrative approach to diagnose pancreatic cystic lesions using EUS-FNA cytology and cyst fluid analysis, along with clinical, radiologic, histologic, genetic, and molecular characteristics. DATA SOURCES.— The review and analysis of the latest literature describing pancreatic cystic lesions. CONCLUSIONS.— Accurate diagnosis of PCLs requires a multidisciplinary and multimodal team approach, including the integration of clinical findings, imaging, cytology, cyst fluid analysis, and molecular testing.

Abstract
Background Solid pseudopapillary neoplasms (SPN) of the pancreas are rare pancreatic neoplasms where complete resection is the cornerstone in management. It has been demonstrated in previous studies that minimally invasive surgical approaches are effective management options in treating SPNs of the distal pancreas. The purpose of this study is to evaluate the feasibility of minimally invasive surgery in treating SPNs of the uncinate, head, and neck of the pancreas. Methods Data from 2005 to 2017 at Severance Hospital of the Yonsei University Health systems in Seoul, South Korea, were retrospectively collected for 25 patients who were diagnosed with SPN of the uncinate, head, and neck of the pancreas and who underwent curative resection. Three groups of patients were considered, depending on the year of surgery, in order to determine trends in the surgical management of SPN. The patients were also divided into two groups corresponding to the type of operation done (minimally invasive surgery vs. open surgery). Perioperative patient data, including age, gender, body mass index (BMI), tumor size, and operation done, were compared and analyzed statistically. Long-term nutritional effects were measured using the Controlling Nutritional Status (CONUT) scoring system. Results There were no statistically significant differences in age, gender, BMI, symptomatic presentation, operation type, tumor size, and tumor stage between the three time periods. In comparing between minimally invasive and open surgery, there were no statistically significant differences in age, gender, symptomatic presentation, BMI, tumor size, preoperative stage, type of operation, operation time, pancreatic duct size, post-operative pancreatic fistula (POPF) grade, death associated with disease, recurrence, pathological parameters, and change in CONUT score. There was a significant difference in tumor size (4.5 ± 1.8 vs. 2.6 ± 1.0 cm, p = 0.004), blood loss (664.2 ± 512.4 vs. 277.7 ± 250.8 mL, p = 0.024), need to transfuse (33% vs. 0%, p = 0.023), hospital length of stay (27.4 ± 15.3 vs. 11.5 ± 5.3 days, p = 0.002), and complication rate (75% vs. 30.8%, p = 0.027) between the two groups. Conclusions In appropriately selected patients with SPNs of the uncinate, head, and neck of the pancreas, a minimally invasive surgical approach offers at least equal oncologic and nutritional outcomes, while demonstrating decreased complications and decreased hospital length of stay compared with that of an open surgical approach.

Abstract
BACKGROUND Solid pseudopapillary neoplasms (SPN) of the pancreas are a rare and low-grade malignant entity with a female predominance. However, it also occurs in males, but the rarity and lack of concern makes its clinicopathological features unclarified. METHODS The morphological, immunohistochemical, prognostic features and CTNNB1 exon 3 mutation status of SPN were compared semi-quantitively between 9 male and 21 female patients. RESULTS SPN in males grew in a distinctive solid pattern, with abundant fibrotic stroma and clear cells. Collagen tended to be the main component of tumor stroma in males, while hyaluronan composed a considerable proportion in females. A much stronger expression of androgen receptor (AR) was found in males, and CD56 and/or synaptophysin (Syn) was expressed frequently in both genders. All patients survived. One male patient had post-operational liver nodules and accepted interventional therapy without biopsy. Mutations of CTNNB1 exon 3 were observed in all cases, distributed at codon 32, 33 and 37 in both genders, as well as 34, 41 and 62 in females. CONCLUSION SPN in males presented with significantly different morphological features from that in females, which might be helpful in differential diagnosis, especially when with extensive positivity for CD56 and/or Syn. The stronger expression of AR in males might be a clue to explore the underlying mechanism of the gender difference.

Backgrounds/Aims Solid pseudopapillary neoplasm (SPPN) is typically seen in young healthy females who would likely benefit from minimally-invasive pancreatectomy (MIP). A few comparative studies have suggested that MIP is associated with favorable outcomes when compared to the open approach for SPPN. This study aims to mitigate potential selection bias by performing a matched case-control study comparing MIP vs open pancreatectomy (OP) for SPPN. Methods We performed a single-institution retrospective electronic chart review of all patients who underwent surgery for pathologically confirmed SPPN between 2000 and 2017. A 2:1 matched comparison using age, gender, tumor size and the type of pancreatectomy was performed between OP and MIP. Results A total of 40 patients with a median age of 40.3 years (range 16.5-64.4) and female sex predominance (n=34, 85.0%) underwent surgery during the study period. Nine patients underwent MIP. Matched comparison between 18 OP and 9 MIP demonstrated that MIP was associated with a longer median operating time (305 vs 180 min, p=0.046) and shorter median postoperative stay (6 vs 9 days, p=0.015). There were no significant differences in intraoperative blood loss, blood transfusion requirements, postoperative morbidity (including postoperative pancreatic fistula) and mortality, resection margins, lymph node yield and long-term survival. Conclusions MIP is a safe and viable option in the management of SPPN with the benefit of a shorter postoperative length of stay at the expense of a longer operation time. There was no significant difference in oncologic outcomes between both groups of patients.

Laparoscopic Distal Pancreatectomy of a Solid Pseudopapillary Tumor (SPT) Achieves Long-Term Oncologic Safety and Multiorgan Preservation. European J Pediatr Surg Rep 2019; 7:e58-e62. [PMID: 31440438 PMCID: PMC6703992 DOI: 10.1055/s-0039-1693999] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Accepted: 06/18/2019] [Indexed: 02/06/2023] Open
Abstract
The oncological safety of a laparoscopic approach for solid pseudopapillary tumors (SPTs) of the pancreas remains a matter of debate. We present the long-term follow-up of an adolescent girl with an SPT in the pancreatic tail. A multimodality workup including magnetic resonance imaging (MRI) revealed a complex, spherical mass of 4.4 cm × 3.6 cm × 4 cm most likely located in the pancreatic tail. All routine laboratory investigations and tumor markers were within normal limits (alpha fetoprotein [AFP], cancer antigen 125 [CA125], CA 19-9, carcinoembryonic antigen [CEA], adrenocorticotropic hormone [ACTH]). Diagnostic laparoscopy was performed to verify the origin of the tumor in the pancreatic tail. In a three-port technique the tumor was mobilized of the splenic vessels until a distal pancreatectomy could be completed. Histopathological examination confirmed the complete resection of a low-grade malignant SPT. The postoperative course was unremarkable. Regular pediatric oncological follow-up examinations for 3 years, including MRI every 6 months, ruled out recurrence and confirmed preservation of splenic and pancreatic functions. While data about the technical feasibility of a laparoscopic approach to pancreatic SPT are already available, this pediatric case report adds a long-term oncological and functional success to the available literature.

Abstract
PURPOSES Microscopic aggressive behaviors may be related with the prognosis of solid pseudopapillary neoplasms (SPNs). In this study, we investigate computed tomography (CT) features and differential diagnosis of aggressive and non-aggressive SPNs in pancreas. MATERIALS AND METHODS 122 patients with pathologically proven SPNs in pancreas were included. Patients' age, tumor site, texture, shape, margins, exophytic growth, capsule, calcification, hemorrhage, pancreatic duct dilatation or pancreatic parenchyma atrophy, peripancreatic infiltration or metastases, vascular encasement, and enhancement pattern were assessed. The diagnostic accuracy was analyzed by using the receiver operating characteristic curve (ROC). RESULTS There were 30 aggressive SPNs and 92 non-aggressive SPNs. Aggressive SPNs showed significantly higher frequencies of an ill-defined margin, patient age > 40.5 years, and tumor size < 42.1 mm, but lower frequencies of complete capsule, hemorrhage compared with non-aggressive SPNs (p < 0.05). Lack of complete capsule and age > 40.5 years were independent risk factors of aggressive SPNs (odd ratio 7.08 and 3.1, respectively). When we applied the two predictors in the logistic regression model, the area under the curve (AUC) was 0.77 with sensitivity of 86.7% and specificity of 55.4%. CONCLUSION Size less than 42.1 mm, lack of complete capsule, ill-defined, and absent bleeding are useful CT imaging features for predicating aggressive SPNs. Patient age > 40.5 years and lack of complete capsule showed acceptable diagnostic performance for discriminating aggressive from non-aggressive SPNs.

Abstract
BACKGROUND Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare neoplasm, which mainly affects young women. The aim of this study was to investigate the clinicopathological features and surgical management of SPNs in our institution. METHODS Patients who underwent surgery for a pathologically confirmed SPN in our institution between January 2008 and October 2018 were collected. Their clinical characteristics and survival associations were analyzed. RESULTS In total, 243 pathologically confirmed patients were analyzed in this study, including 181(74.5%)females and 62(25.5%) males. The mean age was 35.3 years old (range: 12-64 years old) with average tumor size of 4.83 cm (range: 0.8-16 cm). 239 patients underwent complete surgical resection. After median follow-up of 46 months (range: 10-118 months), four patients died due to tumor progression. All the other people were absent of local recurrence or distant metastasis. CONCLUSIONS SPN is a latent malignant tumor with excellent prognosis. Surgical resection is recommended even in the presence of liver metastasis. If possible, function-preserving surgery is advocated. High Ki67 index may predict the malignant potential and poor prognosis of SPNs.

Abstract
RATIONALE About 8384 cases of solid pseudopapillary neoplasms (SPN) of pancreas have been published in English literature, from 1933 to 2018. This is a low-grade tumor that usually occurs in children but is rare in adults and, in exceptional cases, can show extrapancreatic localization. In this paper we present 2 unusual cases of SPNs, 1 with retroperitoneal location (case 1) and 1 that was firstly diagnosed as a G1 neuroendocrine tumor (NET) and showed hepatic metastases after 13 years (case 2). PATIENT CONCERNS No symptoms in first case. The tumor was incidentally diagnosed, during ultrasound examination. In the second case, the metastasis was observed during regular follow-up. DIAGNOSES The diagnosis was established based on the histological features and immunohistochemical profile that showed positivity for vimentin, nuclear β-catenin, cyclin D1, CD10, and SRY-related high-mobility group box 11 and negativity for maspin. INTERVENTIONS Surgical excision, in both cases. OUTCOMES No recurrences in first case, at 5 months after diagnosis. Hepatic metastases in the second case, at 13 years after diagnosis, with portal invasion after another 15 months. LESSONS Without a complex immunoprofile, SPN can be misdiagnosed as NET. SPN can be a low-grade tumor but long-time follow-up is mandatory to detect delayed metastases. A correct diagnosis is necessary for a proper therapeutic management.

Abstract
Solid pseudopapillary neoplasm of the pancreas is a rare tumor of uncertain histogenesis, described separately by Gruber and Frantz, that accounts for between approximately 1% and 3% of pancreatic neoplasms. It is characterized by a cystic and solid pattern of growth patterns with formation of pseudopapillae. It occurs primarily in young women, although cases in children and older patients and men have been reported. The tumor is of low-grade malignant potential, as the majority of the cases are cured by simple but complete surgical resection. Knowledge of the unique morphologic characteristics of this neoplasm is essential for the correct diagnosis. We review herein the pathologic and immunohistochemical features of this neoplasm and its differential diagnosis with other pancreatic tumors.

Abstract
Background and Objectives: Although solid pseudopapillary tumor (SPT) of the pancreas is rare, its diagnosis has increased severalfold in the past decades. We present our experience in the management of SPT, including a patient who experienced tumor rupture during laparoscopy pancreatic resection. Methods: Data on all patients with SPT who were subjected to surgical treatment were retrospectively obtained. Results: Of 20 patients evaluated, 17 (85%) were females. The mean age was 31 years. Tumor size varied from 2.7 × 1.5 to 13.5 × 10.0 cm, with a mean of 6.4 × 7.6 cm. The most common location was the tail and/or body of the pancreas (14 patients [70%]). Pancreatic tumor resection was performed in 19 patients (50%). The type of resection depended on tumor location and size: distal pancreatectomy (n = 13), pancreatoduodenectomy (n = 5), and central pancreatectomy (n = 1) Pancreatic resection was performed via laparoscopy in 7 patients who underwent distal pancreatectomy. Tumor resection was not performed in only 1 patient (5%), due to invasion of mesenteric vessels and presence of liver metastases. One patient had tumor rupture during laparoscopic resection, with no apparent macroscopic dissemination of the tumor. All 19 patients who underwent SPT resection had no tumor recurrence, including a patient with capsule invasion and another patient with tumor rupture during surgical dissection. The mean follow-up time was 38 months (range, 6–72 months). Conclusion: Complete SPT resection is possible in most patients, with a low recurrence rate. Because of its large size, laparoscopic resection of SPT's should be performed only by experienced surgeons to avoid tumor rupture.

Abstract
Purpose Laparoscopic distal pancreatectomy (LDP) has been widely performed for solid pseudopapillary neoplasm (SPN) involving the body or tail of the pancreas. However, it has not been established whether spleen preservation in LDP is oncologically safe for the treatment of SPN with malignant potential. In this study, we compared the short- and long-term outcomes between patients with SPN who underwent laparoscopic spleen-preserving distal pancreatectomy (LSPDP) vs laparoscopic distal pancreatectomy with splenectomy (LDPS). Methods We retrospectively reviewed the medical records of 46 patients with SPN who underwent LDP between January 2005 and November 2016. Patients were divided into 2 groups according to spleen preservation: the LSPDP group (n=32) and the LDPS group (n=14). Clinicopathologic characteristics and perioperative outcomes were compared between groups. Results There were no significant differences in pathologic variables, including tumor size, tumor location, node status, angiolymphatic invasion, or perineural invasion between groups. Median operating time was significantly longer in the LSPDP group vs the LDPS group (243 vs 172 minutes; p=0.006). Estimated intraoperative blood loss was also significantly greater in the LSPDP group (310 vs 167 ml; p=0.063). There were no significant differences in incidence of postoperative complications (≥ Clavien-Dindo class IIIa) or pancreatic fistula between groups. After a median follow-up of 35 months (range, 3~153 months), there was no recurrence or disease-specific mortality in either group. Conclusion The results show that LSPDP is an oncologically safe procedure for SPN involving the body or tail of the pancreas.

Abstract
BACKGROUND To delineate the features of multi-detector computed tomography (MDCT) images and clinical characteristics of pancreatic solid pseudopapillary tumors (SPTs) of the pancreas in asymptomatic patients and compare these features and characteristics between asymptomatic and symptomatic patients. METHODS This work is a retrospective study approved by our institutional review board. MDCT images and clinical data of 109 patients with pathologically proven SPTs obtained from October 2008 to October 2016 were reviewed. Patients were categorized into two groups: asymptomatic patients and patients with symptomatic disease. Cases were reviewed to determine the reason for detection, intervention, shape, diameter, location, calcification, encapsulation, internal composition, CT attenuation, enhancement pattern, and tumor pathology. Clinical factors and imaging features were also compared between groups. Statistical analysis was performed using χ2 and t-tests. RESULTS Data from 49 asymptomatic and 60 symptomatic patients were collected. Asymptomatic SPTs were identified most frequently during routine health examination (18 patients, 36.7%), various screening purposes (12 patients, 24.5%), and traumatic injury (9 patients, 18.4%). Except for a smaller tumor size (5.8 cm in asymptomatic SPTs vs. 7.4 cm in symptomatic SPTs, P = 0.023), the clinical factors or imaging features of asymptomatic patients were very similar to those of symptomatic patients. CONCLUSIONS The current research is the first single-center study to characterize SPTs in asymptomatic patients. Asymptomatic SPTs are gradually being identified with greater frequency. Although generally smaller in size than that in symptomatic patients, an asymptomatic pancreatic mass with the typical imaging features of SPT may be found, the treatment for which is similar to that for symptomatic patients. Evaluating asymptomatic SPTs requires further systematic and multi-center trials.

Abstract
Background Annual pancreatic cancer incidence rates have been increasing. We examine pancreatic cancer incidence trends by demographics and histologic type. Methods Data from the Surveillance, Epidemiology and End Results (SEER) registries were available to assess temporal trends and pancreatic cancer rates from 1974 to 2013. Results Pancreatic cancer incidence rates declined between the 1970s and 1990s but increased from 1994 to 2013 among White males. Among non-Hispanic White and Hispanic males, the annual percent change (APC) in incidence between 1992 and 2013 was 0.84% and 0.73%, respectively. Rates also rose among White non-Hispanic, Hispanic and Asian females (APC = 0.81%, 0.56% and 1.23%, respectively) and even more rapidly among females aged 25-34 years (APC > 2.5%). Rates among Black males and females remained unchanged, but higher compared with the other racial/ethnic groups. By histologic type, the increases were greatest for non-secretory endocrine cancers ( > 6%), followed by ductal adenocarcinomas (∼5%) and adenocarcinoma, NOS (∼1.4%)-the largest histologic subgroup of pancreatic cancer. Rates for mucinous adenocarcinomas and poorly specified pancreatic cancer decreased. Overall, incidence rates during 2000-13 were higher among males than females [MF incidence rate ratio (IRR) = 1.28]. The IRR was >1.00 at all ages ≥ 35, but rates among females were higher at younger ages (IRRs 15-24: 0.66, 25-34: 0.81). The MF IRRs for most of the histologic types were elevated among males apart from solid pseudopapillary adenocarcinoma and cystic carcinomas (IRR = 0.22, confidence interval: 0.14-0.34 and 0.52, 0.41-0.65, respectively). Conclusion Pancreatic cancer has been increasing overall, but patterns differ by demographic group and histologic type. Many of the trends parallel changing prevalence of lifestyle risk factors such as smoking, overweight and obesity, and diabetes in the USA, particularly for pancreatic adenocarcinoma, and improved diagnosis methods during the past 40 years.

Abstract
BACKGROUND Solid pseudopapillary pancreatic tumors (SPPT) are an extremely rare entity in pediatric patients. Even if the role of radical surgical resection as primary treatment is well established, data about follow-up after pancreatic resection in children are scant. METHODS A retrospective review of data from the Italian Pediatric Rare Tumor Registry (TREP) was performed. Short-term (<30 days) and long-term complications of different surgical resections, as well as long-term follow-up were evaluated. RESULTS From January 2000 to present, 43 patients (male:female = 8:35) were enrolled. The median age at diagnosis was 13.2 years (range, 7-18). Nine children had an incidental diagnosis, whereas 26 complained of abdominal pain and 4 of palpable mass. Tumors arose either from the head of pancreas (n = 14) or from body/tail (n = 29): only one patient presented with metastatic disease. Resection was complete in all patients (cephalic duodenopancreatectomy vs distal resection). At follow-up (median, 8.4 years; range, 0-17 years), one recurrence occurred in a patient with intraoperative rupture. All patients are alive. Three pancreatic fistulas occurred in the body/tail group, whereas four complications occurred in the head group (one ileal ischemia, two stenosis of the pancreatic duct, and one chylous fistula). CONCLUSION Surgery is the best therapeutic option for these tumors; hence, complete resection is mandatory. Extensive resections, including cephalic duodenopancreatectomy, are safe when performed in specialized centers. Long-term follow-up should be aimed to detect tumor recurrence and to evaluate residual pancreatic function.

Abstract
Solid pseudopapillary neoplasms of the pancreas are rare neoplasms that have been shown to harbor recurrent somatic pathogenic variants in the beta-catenin gene, CTNNB1. Here, we used targeted next generation sequencing to analyze these tumors for other associated mutations. Six cases of solid pseudopapillary neoplasms were studied. DNA extracted from formalin-fixed paraffin embedded tissue blocks was analyzed using the Ion Torrent platform, with the 50-gene Ampliseq Cancer Hotspot Panel v2 (CHPv2), with further variant validation performed by Sanger sequencing. Four tumors (67%) were confirmed to harbor mutations within CTNNB1, two with c.109T > G p.(Ser37Ala) and two with c.94G > A p.(Asp32Asn). One case showed a frameshift deletion in the Adenomatous Polyposis Coli gene, APC c.3964delG p.(Glu1322Lysfs*93) with a variant allele frequency of 42.6%. Sanger sequencing on non-tumoral tissue confirmed the variant was somatic. The patient with the APC mutation developed metastasis and died. In addition to the four cases harboring CTNNB1 variants, we found a case characterized by poor outcome, showing a rare frameshift deletion in the APC gene. Since the APC product interacts with beta-catenin, APC variants may, in addition to CTNNB1, contribute to the pathogenesis of solid pseudopapillary neoplasms via the Wnt signaling pathway.

Abstract
Background: Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare pancreatic tumors. This study summarizes the clinicopathological characteristics and treatment outcomes of SPN patients through a 10-year single-center case series. Materials and Methods: Medical records of patients diagnosed with SPNs and who underwent surgery between August 2007 and July 2017 at Qilu Hospital, Shandong University, were retrospectively analyzed. Results: This study included 91 patients: 13 males/78 females, mean age 28.8 ± 11.5 years. Among the cases, 38.5% were incidentally confirmed without specific symptoms, while the others displayed various abdominal symptoms. All patients had single pancreatic lesions, and 1 patient presented with liver metastasis. Abdominal enhanced computed tomography, magnetic resonance imaging, and endoscopic ultrasound were the diagnostic imaging techniques used to identify SPNs. All patients had successful surgical removal of their tumors; 28 patients underwent laparoscopy. During the 2-121-month follow-up period, 1 patient died of lung metastasis and multiple organ failure at 35 months postoperatively, but no other tumor recurrence or metastasis was found. Conclusions: SPN usually occurs in the young female population and presents with various clinical characteristics. Mixed solid-cystic masses with calcification or hemorrhage are typical morphological tumor features. Minimally invasive organ-/function-preserving operations are advocated for benign cases, while aggressive radical resection should be performed in patients with local invasion or distant metastasis.

Abstract
Solid pseudopapillary neoplasm with marked parenchymal atrophy of the distal pancreas. No acinar cells were observed, indicating exocrine dysfunction of atrophic parenchyma. The vestige of main pancreatic duct was observed in the distal atrophic pancreas. Central pancreatectomy without anastomosis of distal side of pancreas was performed.
Introduction Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare neoplasm, affecting primarily young females. Because SPNs are of low-malignancy, they rarely obstruct the main pancreatic duct (MPD) and cause atrophy of the distal pancreas even if their tumor sizes are large. Presentation of case A 35-year-old female was referred to our hospital due to pancreatic tumor. Imaging findings showed the presence of well-defined round tumor in the body of the pancreas with 25-mm in diameter. The pancreas parenchyma distal to the tumor was markedly atrophic, and MPD dilatation was not observed. The lesion was diagnosed as SPN by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), and central pancreatectomy was performed. Intraoperative frozen section of the distal atrophic pancreas showed no evidence of acinar cells, indicating exocrine dysfunction. Therefore, we closed distal pancreas stump instead of reconstruction. In the distal atrophic parenchyma, scattered foci of islets of Langerhans and the vestige of dilated MPD were observed. She has shown neither endocrine nor exocrine insufficiency after surgery. Discussion SPNs are usually found without atrophic change of distal pancreas. To the best of our knowledge, this is the first report of SPN in which exocrine dysfunction of atrophic pancreas was demonstrated pathologically and central pancreatectomy without anastomosis of distal pancreas was chosen for the surgical treatment. Conclusion We reported a very rare case of SPN with marked distal parenchymal atrophy. We successfully performed central pancreatectomy without reconstruction.

Abstract
Solid pseudopapillary neoplasm of the pancreas is a rare tumor of low malignancy that occurs most often in females. The study describes the clinicopathologic characteristics of the tumor and common differential diagnoses. Data were collected from a prospectively maintained database. Of 1661 patients operated for pancreatic tumors between January 2001 and September 2018, 15 patients were recorded. Patients included 12 females and 3 males, median age 40 (range 10 -87) years. Computed tomography or magnetic resonance imaging was diagnostic in eight patients and a preoperative biopsy in eight out of 10 patients. Median tumor size was 5 cm (range 2 -16 cm), 12 tumors were in the head, six in the body, and three in the tail of the gland. All patients except one had radical resection including one with hepatic and lymph node metastases, no patient underwent oncologic treatment. All patients are alive from 17.5 to 209.4 months postoperatively and without recurrence. Radical operation is usually curative and should also be offered to patients with metastases or recurrence as oncologic treatment has limited effect.

Abstract
BACKGROUND To overcome the limitations of using cytological specimen alone for the diagnosis of challenging pancreatic lesions, biopsy needles have been developed to procure histological specimens during EUS, especially for the discrimination of several specific pancreatic tumors requiring adequate histological samples. The aim of this study was to compare the diagnostic yield of EUS-guided 22-gauge (G) fine needle aspiration (FNA) needles and 22G fine needle biopsy (FNB) needles for sampling pancreatic masses. METHODS We conducted a retrospective study of all EUS-guided sampling performed between November 2012 and April 2016. 422 cases sampled with a 22G FNA needle (N = 254) or a 22G FNB needle (N = 168) were recruited for this study. The specimen quality analyses, technical characteristics, accuracy, sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs) for the pancreatic masses were reviewed and compared. RESULTS There was no significant difference in the procurement of adequate histological specimens (75.0% vs. 79.5%; p = .277) or the presence of diagnostic histological specimens (71.3% vs. 77.4%; p = .155) between FNA and FNB groups, respectively. There were also no significant differences in the accuracy, sensitivity, specificity, PPVs, or NPVs of the cytological, histological, and overall analyses for FNA and FNB groups in the diagnosis of pancreatic malignancy. However, 22G biopsy needles demonstrated a better histological diagnostic yield in the discrimination of pancreatic adenocarcinoma and non-adenocarcinoma pancreatic neoplasms than 22G FNA needles (69.8% vs. 57.9%, p = .033). CONCLUSIONS 22G FNB needle demonstrated a better histological diagnostic yield in the differentiation between pancreatic adenocarcinoma and non-adenocarcinoma pancreatic neoplasms.

Abstract
An increase in the diagnosis of pancreatic cystic neoplasm has been described lately. Surgical treatment or surveillance is advised depending on the type of lesion diagnosed. The most accurate diagnostic approach is needed to make the best therapeutic decision. Endoscopic ultrasound is a very valuable tool in the evaluation of pancreatic cystic neoplasm. It generates high-quality images and allows the possibility of sampling the cystic fluid for cytology, microbiological and molecular evaluation. Even with this evaluation, the sensitivity of this approach is not always adequate. New technological resources have been developed to try to improve the diagnostic accuracy of pancreatic cystic neoplasms. The two most promising techniques are needle-based confocal laser endomicroscopy and contrast-enhanced harmonic endoscopic ultrasound. Needle-based confocal laser endomicroscopy allows a microscopic evaluation of mucosal glands and vascular pattern, to differentiate mucinous from non-mucinous lesions. Contrast-enhanced harmonic endoscopic ultrasound is used for the vascular evaluation of the microcirculation of the cyst wall and mural nodule, mainly to make the difference between malignant nodules and mucus plugs. A combination of these different diagnostic techniques can improve the diagnostic accuracy of pancreatic cystic neoplasms to offer the adequate therapeutic decision.

Abstract
Central pancreatectomy (CP) is a well-described procedure done for neck and proximal body tumors of the pancreas. It can be done for benign lesions where an adequate length of normal distal pancreas will be left leading to organ preservation. The currently described benefit of the procedure is decreased long-term morbidity due to retention of both the spleen and the preservation of functioning pancreas. This is usually dependent on the preservation of distal pancreatic vascularity by splenic artery preservation. Many studies have described splenic preservation by Warshaw technique by safeguarding the short gastric (SGA) and left gastroepiploic (LGEA) vessels in case of distal pancreatectomy. However, distal pancreatic preservation during CP with splenic vessels ligation is not given a significant mention in the current literature in relation to Warshaw technique. Here, we present a 19-year-old girl diagnosed with an exophytic solid pseudopapillary tumor of the pancreatic body that was selected for central pancreatectomy. In view of splenic vessels involvement, she underwent ligation of the splenic vessels and splenic preservation was based on the LGEA and SGA. Distal pancreas was anastomosed with a roux en loop of jejunum and intra-operatively, we were able to demonstrate the back flow in the splenic vessels. Postoperative computed tomography showed adequate enhancement of the spleen along with retrograde blood flow into the distal splenic artery with enhancement of the distal pancreas. Her postoperative period went uneventful. Thus CP with extended Warshaw technique is a safe and feasible procedure where indicated.

Abstract
Background The role of progesterone receptor (PR) has been reported in a series of pancreatic cysts. However, the relationship between PR and prognosis of solid pseudopapillary neoplasm of the pancreas (SPNP) has not been elucidated so far. The aim of our study was to evaluate the prognostic value of PR in SPNP. Methods A total of 76 patients with SPNP treated in our institution from January 2012 to December 2017 were included. Demographic parameters, laboratory data, pathologic information and clinical outcomes were analyzed by the use of survival analysis. In addition, a pooled case series was performed to evaluate the results. Results The institutional data included 76 patients (17 male and 59 female) ranging from 8 to 90 years (median, 30 years) in age. Kaplan-Meier survival analysis confirmed negative PR result was significantly associated with poorer disease-free survival (DFS) and disease-specific survival (DSS) (both P < 0.001). In the pooled analysis, a total of 62 studies comprising 214 patients with SPNP were included. After multivariable cox analysis, negative PR result remained an independent prognostic factor for SPNP (DFS HR: 14.50, 95% CI: 1.98–106.05, P = 0.008; DSS HR: 9.15, 95% CI: 1.89–44.17, P = 0.006). Conclusion Our results indicated the role of PR in predicting adverse outcome of patients with SPNP and negative PR result may serve as a potential prognostic factor.

Abstract
Solid pseudopapillary neoplasm is a rare tumor of the pancreas. These tumors are considered to have low malignant potential with good prognosis. Due to its rarity, details about clinical presentation and management of the disease are not very clear. This study aims to share our experience and to describe management of the disease. We retrospectively evaluated patients 13 patients diagnosed with SPT on histopathological examination of resected specimen. Data on their clinicopathological, management-related factors, and follow-up was collected. All the patients were females, with a median age of 20 years. Abdominal pain was the most common presentation. The mean tumor size was 6.5 cm and majority of tumors were located in the head region. R0 resection was obtained in all the patients. All patients were disease-free with a median follow-up of 68 months. Excellent prognosis can be achieved with a margin-negative resection in these tumors. Adjacent organ or vascular involvement is not a contraindication for surgical resection.

Abstract
BACKGROUND Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare tumors considered to be benign although 10% to 15% of SPNs have been reported to be aggressive. Due to its rarity, there have only been a few cases reported regarding the clinical course of patients with aggressive SPNs. The goal of this study is to describe the clinical course of patients diagnosed with aggressive SPNs. METHODS A PubMed search was done looking for articles describing the clinical course of patients diagnosed with SPN that locally invaded, recurred, or metastasized. Institutional experience was also added to the pooled data. Patient information was extracted from the articles. Survival and recurrence curves were plotted and factors associated with survival and recurrences were analyzed. RESULTS A total of 59 patients were identified to have aggressive SPN. Seven patients were males and 52 were females and the mean age was 37.44 ± 2.21 years. Systemic metastasis constituted 81.4% while recurrence and deep tissue invasion were found in 11.9% and 6.8% of the patients, respectively. Disease-free survival was 45 ± 6.28 months and disease-specific survival was 152.67 ± 12.8 months. In survival analysis, age, gender, tumor size, tumor location, combined resection, type of recurrence, and stage IV on diagnosis were not significant factors in predicting survival. However, an unresectable tumor (hazards ratio [HR] = 4.871, 95% confidence interval [CI] 1.480-16.03, P = .009), and metastasis within 36 months (HR = 6.399, 95% CI: 1.390-29.452, P = .017) were identified as independent variables in predicting survival. CONCLUSION SPNs of the pancreas carry a favorable course. Despite having aggressive properties, patients can still survive for more than 10 years as long as the tumor can be resected completely.

Abstract
Solid pseudopapillary neoplasms (SPNs) are the most common pediatric pancreatic tumor; however, most data in children are extrapolated from adults. This study describes a young presentation of SPN in a 5-year-old girl and presents a comprehensive systematic review of the literature regarding SPNs in children. A systematic review was performed using PubMed and Embase for all articles in English using predetermined search terms, including "solid pseudopapillary neoplasm" and "pediatric" and historical terms for SPN. A total of 523 pediatric patients were identified in 135 articles. Eighty-three percent of patients were female, and median age was 13.6 years. Abdominal pain was the most frequent presenting symptom (78%), and median tumor size was 8.2 cm. The pancreatic head was involved in 46% of cases. Computed tomographic scan was the most common imaging modality (87%), and 61% were diagnosed by fine needle aspiration. Surgical resection was reported in 507 patients, with a complication rate of 21.1% reported in 393 patients. Only 3.8% received adjuvant therapy, and 6.7% had recurrent disease. Solid pseudopapillary neoplasms of the pancreas are rare tumors in childhood. Male sex and pancreatic head involvement are seen more often in children than in adults. Surgery remains the mainstay of treatment with excellent results.

Abstract
Frantz' tumours or solid pseudopapillary tumours of the pancreas are rare neoplasms with low malignant potential. Young women in the second to third decades of life are more frequently affected. The treatment of choice is resection of the lesion, which is often curative. The recurrence is uncommon when radical surgical resection is used. Radiological characteristics are important for the correct diagnosis, since the preoperative planning is fundamental to obtain the cure. The objective of this study is to report a rare case of locoregional recurrence and to review the radiological findings of solid pseudopapillary tumours of the pancreas in the literature, as well to know the incidence and risk factors of tumor recurrence. This case report is from a 37-year-old female patient evaluated at an Oncologic Hospital, in the city of São Paulo, Brazil, who presented an uncommon evolution of the disease, characterized by local recurrence despite the complete resection of the primary lesion with free margins.

Abstract
Ductal adenocarcinoma is the most common pancreatic neoplasm. A variety of pancreatic lesions mimic pancreas ductal adenocarcinoma (PDAC), such as high-grade neuroendocrine tumors, small solid pseudopapillary tumors, metastases, focal autoimmune pancreatitis, and groove pancreatitis. These occasionally look similar in images, but they have differential diagnosis points. Familiarity with the imaging features of PDAC and its mimics is paramount for correct diagnosis and management of patients. In this essay, we describe imaging findings of PDAC and its mimics for differential diagnosis.

Abstract
Solid pseudopapillary neoplasm (SPN) is a rare tumor with malignant potential which is generally located in the tail of pancreas. The prevalence of SPN has increased with widespread use of cross sectional imaging. SPN is often misdiagnosed due to nonspecific clinical presentation and accurate diagnosis is essential for optimal management. Endoscopic ultrasound-FNA with immunohistochemistry can help in preoperative diagnosis. Surgery is the treatment of choice and a successful R0 resection is curative. Overall, SPN has a good prognosis. This review article focuses on pathogenesis, diagnosis and management of SPN.

Abstract
INTRODUCTION This study reports the clinicopathological characteristics and the perioperative and long-term treatment outcomes after aggressive surgical resection in solid pseudopapillary tumor (SPT) of the pancreas performed at a high volume center for pancreatic surgery in India. MATERIALS AND METHODS We analyzed a prospectively maintained database of the patients operated for SPT at Tata Memorial Hospital, India over a period of 11 years from February 2007 to February 2018. RESULTS Fifty consecutive patients operated for SPT, during the study period were included. The median age at presentation was 24 years. Majority of the patients (43/50) were female (86%). Disease was predominantly localized in the head and uncinate process of pancreas (66%). Median tumor size was 7.7 cm (Range 1.6-15 cm). Tumor extent was radiologically defined as borderline resectable or locally advanced in 48% (n = 24) patients. Forty-six major pancreatic resections were performed, which included 10 (21%) vascular resections, 2 synchronous liver metastasectomies, 1 multi visceral resection and 5 total pancreaticosplenectomies. Five of these resections were reoperations in patients deemed inoperable on exploration at other centers. R0 resection was achieved in 47 patients (98%). Postoperative major morbidity was 19% and there was no mortality. At a median follow-up of 29 months (Range, 1-121 months), all patients were alive without any recurrence. CONCLUSION Aggressive complete surgical resection of SPT achieves excellent long-term survival. Surgery, especially for large and borderline resectable tumors, can be potentially complex and should be performed at high-volume centers to provide the best chance of cure.

Abstract
There have been no reports of ruptured solid pseudopapillary neoplasm (SPN) into adjacent organs. A 22-year-old female was referred to our hospital for treatment of a pancreatic head tumor. Computed tomography (CT) examination at our hospital showed a 5-cm tumor containing air, although CT at a previous hospital revealed an 8-cm tumor without air. Thus, a spontaneous rupture of the tumor into the duodenum was suspected. Subtotal stomach preserving pancreaticoduodenectomy with combined resection of the portal vein was performed. Contrast radiography of resected specimen showed the medium injected into the tumor leaking out from the 2nd portion of the duodenum. Histologically, the patient was diagnosed as SPN. Microscopic invasion to the portal vein and duodenum were also confirmed. She did not experience any postoperative complications and has remained well without any signs of recurrence during 2 years of follow-up. Although there have been 14 studies reporting ruptured SPN, this is the first report of SPN that spontaneously ruptured into the duodenum. An extremely rare case of SPN of the pancreatic head that spontaneously ruptured into the duodenum was reported.

Abstract
OBJECTIVES Prognostic factors for solid pseudopapillary neoplasms (SPN) of the pancreas have been incompletely defined in the literature. We aimed to use the National Cancer Database to describe survival and characterize prognostic factors in patients with pancreatic pseudopapillary neoplasms. METHODS We identified 304 patients with pancreatic SPN diagnosed between 2004 and 2012 using the National Cancer Database. All patients were included in the survival analysis. Kaplan-Meier method, χ, and log-rank tests were used for statistical analysis. Cox proportional hazard regression model was used for multivariate analysis. RESULTS The median age at diagnosis was 36.5 years. Eighty-five percent of patients were female, 69% were white, and 25% were black. Metastases were observed in 5% of patients. Median tumor size was 5.1 cm. Ninety-two percent of patients underwent primary tumor resection. At 60 months, 98% of patients who underwent resection were alive, and 40% who did not undergo resection were alive. On multivariate analysis, female sex, resection of primary tumor, and absence of metastasis were correlated with improved survival. CONCLUSIONS Patients with SPN who undergo resection have an excellent survival at 5 years. Surgery should be considered in all patients with this diagnosis.

Abstract
PURPOSE Solid pseudopapillary neoplasm (SPN) is a rare, low-grade neoplasm with excellent prognosis. In this study, we evaluated clinicopathological characteristics of patients diagnosed with SPN retrospectively. METHODS This is a retrospective study intended to characterize patients with the diagnosis of SPN between 2005 and 2015. Clinicopathological features, recurrence rate, and overall survival of 28 patients were recorded. Malignant SPN criteria were defined as the presence of distant metastasis (developed at diagnosis or during follow up) or lymph node involvement. RESULTS The mean age at diagnosis was 42 (range: 17-41). Among patients, 82% (n = 23) were female and 17.9% (n = 5) were male. The mean size of tumor was 5.81 cm (range: 2-15). The mean follow up period was 55.6 months, 1-year survival was 96.5% and 5-year survival rate was 88%. A total of 25 patients were alive at the end of follow-up period and 3 of the patients became exitus due to disease. Two patients had a metastatic presentation in livers at the diagnosis and metastasis developed in 3 patients during follow-up (liver of 1 patient, peritoneum in 1 patient and liver and peritoneum in 1 patient). The reason of admission was headache in 68% patients. The type of operation was frequently subtotal pancreatectomy (n = 11, 39.3%) and distal pancreatectomy (n = 10, 35.7%). Tumors were located frequently in body and tail regions (n = 18, 64.3%) and the number of patients with malignant criteria was 6 (21.4%). Although the mean age of malignant patients was significantly higher than benign patients (P = 0.046), there was no significant difference between 2 groups in terms of gender, tumor size, capsule invasion, perineural invasion, vascular invasion, and margin status. CONCLUSION SPN is a rarely seen tumor with low malignity potential. Surgical resection provides long-term survival rate even in local invasion or metastasis conditions.

Abstract
Background Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare neoplasms with low malignant behavior. These neoplasms can be aggressive and cause bad ending of SPN patients. The purpose of this article is to identify certain prognostic factors. Method We retrospectively evaluated 196 patients from our hospital and SEER database. We identified that tumor location was an independent prognostic indicator of SPN patients. Results DSS and OS of pancreatic head SPNs (HOP) were significantly shorter than those of other locations (OOP). Operation methods and age were different between HOP and OOP groups. Compared to OOP group, patients in HOP group were younger. Operation time was longer, and hospital stays were longer. Conclusion This work suggests that pancreatic head SPNs have distinct clinicopathological features and clinical outcome. It is urgent to optimize the treatment of SPN patients and identify effective prognostic indicators of SPN.
