Abstract
OBJECTIVES The aim of the study is to summary the clinicopathological characteristics and surgical outcomes of solid pseudopapillary neoplasm (SPN) of the pancreas. METHODS In this retrospective study, the information of 118 patients with SPN from 3 hospitals were analyzed. RESULTS A total of 118 patients. The mean age was 30.8 (standard deviation, 14.7) years and the majority were female (n = 95, 80.5%). Sixty-seven patients (56.8%) had clinical symptoms, of which the most common symptom was abdominal pain (49.6%). The mean tumor size was 5.9 (standard deviation, 2.9) cm. Pseudopapillary architecture was the commonest histologic feature, and β-catenin, CD56, vimentin, neuron-specific enolase, CD10, a1-antitrypsin, cytokeratins showed different degrees of positive expression in immunohistochemical staining. Fourteen patients (11.9%) presented aggressive pathologic behavior, which was correlated to the incomplete tumor capsule. At a median follow-up of 59.2 months, the recurrence rate was 1.8% and the overall 5-year survival rate was 97.7%. CONCLUSIONS Solid pseudopapillary neoplasm of the pancreas is a potentially low-grade malignant tumor that most frequently found in young females. Its clinical manifestations are nonspecific and the diagnosis mostly depends on pathological examination. Surgical resection is the first choice of treatment for SPN with a good prognosis.

Abstract
Solid pseudopapillary neoplasms (SPNs) are frequently seen in young women. Although the behavior pattern varies, these rare lesions generally have a low malignant potential. In this study, the aim was to investigate the effect of clinicopathological features of lesions on the recurrence in and survival of patients. In this study, patients of our clinic who were pathologically diagnosed with SPN after pancreatic surgery between July 2008 and December 2020 were evaluated retrospectively. Patients' age, gender, comorbidities, symptoms at the time of application, preoperative CA 19-9, CEA value, preoperative cross-sectional diagnostic imaging method and lesion characteristics, surgery, postoperative complications, length of hospital stay, and histopathological features were evaluated. Early and late mortality, overall survival, disease-free survival, and recurrence rate were determined. Four of the 23 patients diagnosed with SPN were male and the median age was 29 (23-47) years. Of the study patients, 69.56% experienced pain symptoms and 30.43% were asymptomatic. The median tumor size was 4 cm (1.5-15). The most common surgical procedure was distal pancreatectomy (56.5%). The median length of hospital stays was 5 (3-120) days and morbidity was observed in 9 cases (39.13%). The mortality rate was 4.35%. The mean follow-up period in the series was 53 (8-132) months and none of the patients developed recurrence. In this study, no significant difference was found regarding recurrence in patients with SPN with histopathologically aggressive biological behavior. The overall survival rate was 95.7%. SPNs are rare lesions with low malignant potential. SPNs are associated with longer-term survival after surgical resection.

Abstract
Due to the rarity of the disease, there are no guidelines or consensus for the management of solid pseudopapillary neoplasm of the pancreas with liver metastasis. We describe a patient with solid pseudopapillary neoplasm of the pancreas with multiple liver metastases who was successfully managed with staged resection. A previously healthy 50-year-old female presented to the clinic with dull epigastric pain. The contrast-enhanced computed tomography showed a well-defined cystic lesion at the distal body and tail of the pancreas with multiple liver deposits. A core needle liver biopsy was suspicious of a hepatic epithelioid hemangioendothelioma. A distal pancreatectomy with splenectomy and a left hemi-hepatectomy were performed with a subsequent staged right posterior sectionectomy to address the inadequate future liver remnant. The final histology with immunohistochemistry revealed a pancreatic solid pseudopapillary neoplasm. The patient had satisfactory surgical and oncological outcomes with no recurrence. As these are slow growing tumours, appropriately spaced staged liver resection was feasible to allow hypertrophy of the liver remnant and physiological recovery of the patient. The discrepancy in the histology and cross-sectional imaging led to a pre-operative diagnostic dilemma, and the final diagnosis was reached after surgical resection. Thus, resectable metastatic solid pseudopapillary neoplasm of the pancreas may be offered a primary curative radical surgery before considering other treatment modalities.

Abstract
Simple Summary Predicting the aggressiveness of solid pseudopapillary neoplasms (SPNs) remains a worthwhile goal. The present study aimed to identify perioperative factors that can predict patients who will develop clinically aggressive SPN. A total of 98 patients diagnosed with SPNs were analyzed retrospectively. We found that age (≥40 years; p = 0.039), symptomatic presentation (p = 0.001), tumor size (>10 cm; p < 0.001), positron emission tomography/computed tomography (PET/CT) classification (Type III; p < 0.001), and lymphovascular invasion (p = 0.003) were significantly correlated with aggressive behavior of SPNs. Among these, age ≥40 years, PET/CT Type III configuration, and lymphovascular invasion were independent factors associated with an aggressive SPN. This information can help clinicians develop individualized management and surveillance plans to manage patients more competently. Abstract Predicting the aggressiveness of solid pseudopapillary neoplasms (SPNs) remains an important goal. The present study aimed to identify perioperative factors that can predict patients who will develop clinically aggressive SPN. Records of individuals with pathologically confirmed SPN from 2006 to 2017 were obtained from the patient registry database of Yonsei University, Severance Hospital. For this study, aggressive behavior was defined as SPN that had recurred, metastasized, or involved adjacent organs. A total of 98 patients diagnosed with SPNs were analyzed retrospectively. Of these, 10 were reported to have SPNs with aggressive characteristics. We found that age (≥40 years; p = 0.039), symptomatic presentation (p = 0.001), tumor size (>10 cm; p < 0.001), positron emission tomography/computed tomography (PET/CT) classification (p < 0.001), and lymphovascular invasion (p = 0.003) were significantly correlated with aggressive behavior of SPNs. Multivariate analysis showed that PET/CT configuration (p = 0.002) (exp(β)111.353 (95% confidence interval (CI): 5.960–2081), age ≥40 years (p = 0.015) (exp(β) 23.242 (95% CI: 1.854–291.4)), and lymphovascular invasion (p = 0.021) (exp(β) 22.511 (95% CI: 1.595–317.6)) were the only independent factors associated with aggressive SPN. Our data suggest that age ≥40 years, PET/CT Type III configuration, and lymphovascular invasion are independent factors associated with aggressive SPN. This information can help clinicians develop individualized management and surveillance plans to manage patients more effectively.

Abstract
Extra-pancreatic solid pseudopapillary neoplasms (SPNs) are rare tumours with an overall favourable prognosis and low malignant potential. SPNs with metastatic spread, distant lymph node metastasis and extrapancreatic origin are exceedingly rare. Significant controversy regarding the treatment and the management of metastatic disease exists and, currently, there are no standardised guidelines or treatment recommendations for the use of adjuvant therapy. In this case report, the authors present a patient with widely metastatic SPN of likely ovarian origin with the invasion of the inguinal lymph nodes and multiple abdominal metastatic deposits. Using the currently available literature, the authors discuss treatment options for metastatic SPN of the ovary and highlight the need for continued research in this important field.

Abstract
Solid pseudopapillary tumor (SPT) of the pancreas is an uncommon pathological condition. It is classified as low-grade malignant neoplasm, but aggressive disease can be seen when the tumor size is larger than 5 cm, microscopic malignant features and local invasion are present. Resection of the mass with clear margins is the procedure of choice. However, lymph node dissection may be necessary in large tumors.

Abstract
BACKGROUND Ki-67 has been shown to predict outcome of patients with solid pseudopapillary tumor of the pancreas (SPTP) but has not been incorporated into a formal classification system to predict recurrence-free survival (RFS). METHODS This is a retrospective cohort study of patients with histologically confirmed diagnosis of SPTP who had at least 1 year of follow-up at two tertiary academic centers. Survival data were assessed by Kaplan-Meier method and multivariable Cox regression model. Prognostic performance was compared among various systems. RESULTS A total of 193 consecutive patients were included, ranging in age from 12 to 70 years (median 33 years). Seven patients (3.6%) developed tumor recurrence. The 3-, 5-, and 10-year RFS rates were estimated at 96.9%, 96.1%, and 94.8%, respectively. For the AJCC staging system, patients with stage I had similar prognosis to those with stage II. For the ENETS staging system, patients with stage I to III had similar prognosis. Grade based on Ki-67 was superior to both the AJCC and ENETS systems for predicting survival. Multivariate analysis revealed that large tumor size [> 10 cm; hazard ratio (HR), 6.177 95% confidence interval (CI), 1.289-29.603; P = 0.023] and Ki-67 (HR, 17.199 95% CI, 4.001-73.930; P < 0.001) were independent predictors for RFS. The Fudan Prognostic Index based on the combination of Ki-67 and tumor size showed excellent discrimination for RFS and was more accurate and informative than other grading/staging systems. CONCLUSION The Fudan Prognostic Index better predicts RFS compared with either Ki-67 alone or the current AJCC and ENETS TNM-based staging systems.

Abstract
BACKGROUND Solid pseudopapillary tumors (SPTs) are rare, benign tumors of the pancreas that present as heterogeneous masses. We sought to evaluate the short- and long-term outcomes of surgical resected SPTs. Patients managed via initial surveillance were compared to those who underwent upfront resection. METHODS A prospectively maintained institutional database was used to identify patients who underwent surgical resection for a SPT between 1988 and 2018. Data on clinicopathological features and outcomes were collected and analyzed. RESULTS Seventy-eight patients underwent surgical resection for SPT during the study period. The mean age was 34.0 ± 14.6 years and a majority were female (N = 67, 85.9%) and white (N = 46, 58.9%). Thirty patients (37.9%) were diagnosed incidentally. Imaging-based presumed diagnosis was SPT in 49 patients (62.8%). A majority were located in the body or tail of the pancreas (N = 47, 60.3%), and 48 patients (61.5%) underwent a distal pancreatectomy. The median tumor size was 4.0 cm (IQR, 3.0-6.0), nodal disease was present in three patients (3.9%), and R0 resection was performed in all patients. No difference was observed in clinicopathological features and outcomes between patients who were initially managed via surveillance and those who underwent upfront resection. None of the patients under surveillance had nodal disease or metastasis at the time of resection; however, one of them developed recurrence of disease 95.1 months after resection. At a median follow-up of 36.1 months (IQR, 8.1-62.1), 77 (%) patients were alive and one patient (1.3%) had a recurrence of disease at 95.1 months after resection and subsequently died due to disease. CONCLUSIONS SPTs are rare pancreatic tumors that are diagnosed most frequently in young females. While a majority are benign and have an indolent course, malignant behavior has been observed. Surgical resection can result in exceptional outcomes.

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
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
Since solid pseudopapillary tumor of the pancreas (SPTP) was officially classified by the World Health Organization in 1996, SPTP has recently received special attention in the literature. Studies have shown that SPTP is a heterogeneous tumor, with a small percentage of patients harboring aggressive behaviors. However, criteria for malignancy grade in SPTP have not been well established. The prognosis of SPTP is generally good, with cases having a chance for long-term survival even with recurrence and/or metastasis after surgical resection. The current American Joint Committee on Cancer/Union for International Cancer Control tumor, node, metastasis staging system is not specific to SPTP. The lack of a predictive staging classification that accurately describes the heterogeneity of this disease hinders meaningful research into optimal individualized therapy. Here we summarize and discuss the associated factors proposed for appraisal of the malignant potential and adverse outcome of SPTP.

Abstract
Background: Solid pseudopapillary neoplasm of pancreas is a rare tumor with a low potential for metastasis and recurrence. Long-term outcomes after surgical resection are excellent and recurrences after an R0 resection are extremely rare. Case Presentation: We present an unusual case of a 42-year-old man who had a recurrence of his solid pseudopapillary tumor 4 years after undergoing a distal pancreatectomy and splenectomy and then again a year after his reresection. Conclusions: The lack of histological features deemed to be suggestive of a malignant variant and the aggressive clinical course seen in this case is remarkable. It underscores the fact that despite the low incidence, recurrences of solid pseudopapillary neoplasms of the pancreas do occur and it can be very difficult to predict malignant potential based on radiological or histopathological features.

Abstract
The patient is a girl aged 17 years who originally presented at age 11 years with a solid pseudopapillary tumour (SPT) in the head of the pancreas treated by an R0 pylorus-preserving Whipple procedure. The patient underwent surveillance CT every 3 months for the first year followed by MRI every 6 months. She was noted to have a new liver lesion in Couinaud segment VI highly suspicious for metastasis at 30 months. Liver wedge biopsy confirmed metastatic SPT. Two months later two new lesions were noted in Couinaud segment VII. The family preferred medical management to surgery resulting in a treatment combination of the tyrosine kinase inhibitor sunitinib and hepatic artery embolisation. The patient developed a hepatic abscess following embolisation but recovered with antibiotics. The patient has subsequently been followed with serial MRIs every 3 months, and 20 months following chemoembolisation, she has no evidence of recurrence of the metastases.
