Abstract
OBJECTIVE The purpose of the study was to develop and validate a radiomics model by using contrast-enhanced ultrasound (CEUS) data for pre-operative differential diagnosis of pancreatic cystic neoplasms (PCNs), especially pancreatic serous cystadenoma (SCA). METHODS Patients with pathologically confirmed PCNs who underwent CEUS examination at Chinese PLA hospital from May 2015 to August 2022 were retrospectively collected. Radiomic features were extracted from the regions of interest, which were obtained based on CEUS images. A support vector machine algorithm was used to construct a radiomics model. Moreover, based on the CEUS image features, the CEUS and the combined models were constructed using logistic regression. The performance and clinical utility of the optimal model were evaluated by area under the receiver operating characteristic curve (AUC), sensitivity, specificity and decision curve analysis. RESULTS A total of 113 patients were randomly split into the training (n = 79) and test cohorts (n = 34). These patients were pathologically diagnosed with SCA, mucinous cystadenoma, intraductal papillary mucinous neoplasm and solid-pseudopapillary tumor. The radiomics model achieved an AUC of 0.875 and 0.862 in the training and test cohorts, respectively. The sensitivity and specificity of the radiomics model were 81.5% and 86.5% in the training cohort and 81.8% and 91.3% in the test cohort, respectively, which were higher than or comparable with that of the CEUS model and the combined model. CONCLUSION The radiomics model based on CEUS images had a favorable differential diagnostic performance in distinguishing SCA from other PCNs, which may be beneficial for the exploration of personalized management strategies.

Abstract
Isolated unilateral ovarian tumour without obvious concomitant tubal pathology is unlikely to cause intrabdominal abscess or septicaemia. Benign serous cystadenoma is a fairly common ovarian tumour but rarely causes fatality. We present a patient in mid-30s with massive ovarian serous cystadenoma presenting with abscess and septicaemia, leading to mortality. To our knowledge, no previous serous cystadenoma causing abscess formation has been reported before.

Abstract
ABSTRACT A 2.6-cm solid cystic lesion in the pancreatic head was found in a 51-year-old woman on CT. A pancreatic neuroendocrine tumor was suspected, and a 68 Ga-DOTATATE PET/MRI was performed, which showed increased tracer uptake in the lesion. However, postsurgical pathologic examination indicated a pancreatic serous cystadenoma. Here, we reported a case of microcystic pancreatic serous cystadenoma that could be misdiagnosed as a pancreatic neuroendocrine tumor on a 68 Ga-DOTATATE PET/MRI.

Abstract
BACKGROUND Over the years, the detection rate of pancreatic cystic neoplasms (PCNs) has significantly increased; however, the differential diagnosis and identification of high-risk PCNs remain challenging. We sought to investigate whether chromosomal instability (CIN) features in cell-free DNA in the cystic fluid of PCNs could help to identify high-risk PCNs. METHODS Pancreatic cystic fluid samples from 102 patients with PCNs were intraoperatively collected for detection of CIN using an ultrasensitive chromosomal aneuploidy detector. Clinical and imaging data were retrospectively collected, and statistical analysis was performed to assess the potential role of CIN in clinical practice. RESULTS CIN was investigated in a total of 100 patients. Sixteen of 26 serous cystic cystadenomas (SCAs) harbored deletions of chr3p and/or chr6p, whereas low rates of CIN were detected in mucinous cystic neoplasms. Most malignant PCNs presented with more than one type of CIN; amplification of chr1q and chr8q found in nine and seven of 11 malignant PCNs (81.8% and 63.6%), respectively, could aid in distinguishing high-risk IPMNs from low-risk ones, with a higher sensitivity than imaging. A combination of the mural nodule imaging feature and amplification of chr1q and chr8q achieved a sensitivity of 70.0% and a specificity of 82.4% in identifying high-risk IPMNs. CONCLUSIONS Our work revealed the distinct CIN signature of different types of PCNs. Deletions of chr3p and chr6p defined a subtype of SCAs. Gains of chr1q and chr8q were associated with insidious malignant PCNs and helped identify high-risk IPMNs.

Abstract
Increased use of cross-sectional imaging has resulted in frequent detection of incidental cystic pancreatic lesions. Serous cystadenomas (SCAs) are benign cysts that do not require surgical intervention unless symptomatic. Unfortunately, up to half of SCAs do not have typical imaging findings ("atypical SCAs"), overlap with potentially malignant precursor lesions, and thus pose a diagnostic challenge. We tested whether the analysis of circulating extracellular vesicle (EV) biomarkers using a digital EV screening technology (DEST) could enhance the discrimination of cystic pancreatic lesions and avoid unnecessary surgical intervention in these atypical SCAs. Analysis of 25 different protein biomarkers in plasma EV from 68 patients identified a putative biomarker signature of Das-1, Vimentin, Chromogranin A, and CAIX with high discriminatory power (AUC of 0.99). Analysis of plasma EV for multiplexed markers may thus be helpful in clinical decision-making.

Abstract
Serous cystadenoma (SCA) is the most common cystic neoplasm of the pancreas. Serous cystadenoma is best diagnosed by imaging with computed tomography scan. Fine-needle aspiration cytology is required for definitive preoperative diagnosis. Serous cystadenoma may be sometime difficult to differentiate from pancreatic neuroendocrine tumor (PNET) in the preoperative stage. Differentiating the two entities are important for proper treatment strategy. Serous cystadenoma may be managed in expectant observation. However, all PNETs will need surgical treatment including pancreaticoduodenectomy (PD). Here, we present a rare presentation of serous cystadenoma head of pancreas masquerading as PNET with local compressive symptoms for which Whipple's PD was done successfully.

Abstract
BACKGROUND Although emerging data evidences that EUS-guided needle-based confocal laser endomicroscopy (nCLE) accurately diagnoses pancreatic cystic lesions (PCLs), there are a lack of interobserver agreement (IOA) studies utilizing reference histopathological diagnosis and for specific PCL subtypes. Hence, we sought to assess the IOA, intra-observer reliability (IOR), and diagnostic performance of EUS-nCLE using a large cohort of patients with histopathological diagnosis amongst a broad panel of international observers. METHODS EUS-nCLE videos (n = 76) of subjects with PCLs [intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), serous cystadenoma (SCA), pseudocyst, and cystic-neuroendocrine tumors/solid pseudopapillary neoplasm (cystic-NET/SPN)], simulating clinical prevalence rates were obtained from 3 prospective studies. An international panel of 13 endosonographers with nCLE experience, blinded to all PCL data, evaluated the video library twice with a two-week washout for PCL differentiation (mucinous vs. non-mucinous) and subtype diagnosis. RESULTS The IOA (κ = 0.82, 95% CI 0.77-0.87) and IOR (κ = 0.82, 95% CI 0.78-0.85) were "almost perfect" to differentiate mucinous vs. non-mucinous PCLs. For PCL subtype, IOA was highest for SCA (almost perfect; κ = 0.85), followed by IPMN (substantial, κ = 0.72), and cystic-NET/SPN (substantial, κ = 0.73). The IOA was moderate for MCN (κ = 0.47), and pseudocyst (κ = 0.57). Compared to histopathology, observers differentiated mucinous vs. non-mucinous PCLs with high accuracy (94.8%, 95% CI 93.3-96.1). For detecting specific PCLs subtypes, EUS-nCLE was highly accurate in diagnosing non-mucinous cysts (SCA: 98%; cystic-NET/SPN: 96%; pseudocyst: 96%) and slightly less accurate for mucinous lesions (IPMN: 86%; MCN: 84%). CONCLUSION Diagnosis of PCLs by EUS-nCLE guided virtual biopsy is very accurate and reliable for the most prevalent pancreatic cysts in clinical practice.

Abstract
RATIONALE Gastric-type endocervical adenocarcinoma (GAS) is a rare type of cervical adenocarcinoma that is a mucinous adenocarcinoma with a variety of gastral patterns. To date, there are no systematic clinical diagnosis and treatment guidelines. PATIENT CONCERNS In our case, a 49-year-old woman underwent pelvic magnetic resonance imaging (MRI) due to a pelvic mass, and cervical lesions were unexpectedly found. After receiving relevant surgical treatment, the pathological results showed the particularity of the tumor type-cervical gastric adenocarcinoma with a borderline serous tumor of both appendages and the right ovary. DIAGNOSES Postoperative routine pathological examination showed mucoepithelial metaplasia accompanied by a borderline serous tumor. INTERVENTIONS After gynecological/urinary ultrasound, blood tests, MRI, cervical biopsy, and uterine curettage, "robot-assisted laparoscopic radical hysterectomy + bilateral salpingectomy-ovariectomy + pelvic lymph node dissection + pelvic adhesiolysis" were performed. After the surgery, the patient was treated with radiotherapy and concurrent chemotherapy. OUTCOMES After the operation, radiotherapy, and chemotherapy, the patient had no tumor recurrence and is still in good condition. LESSONS The diagnosis of GAS is relatively difficult, its clinical manifestations lack specificity, and the pathogenesis has nothing to do with human papillomavirus infection. The patient was misdiagnosed with vaginitis at a local hospital. However, we found that MRI and pathological examination were helpful for the diagnosis of the disease. Although there are no relevant guidelines to explain the treatment principles of GAS, we believe that early surgery is conducive to the prognosis of the disease because GAS has a certain tolerance to radiotherapy and chemotherapy.

Abstract
High-grade serous ovarian cancer (HGSOC) is characterized by TP53 mutation and somatic copy number alterations (SCNAs). Here we show that the oncogenic transcription factor EVI1 (ecotropic viral integration site-1) is amplified and overexpressed up to 30% of 1640 HGSOC cases in The Cancer Genome Atlas (TCGA). Functionally, EVI1 promotes proliferation/invasion in vitro and tumor growth of xenograft model in vivo. Importantly, we discover that EVI1 regulates estrogen signaling by directly activating ESR1 (estrogen receptor 1) transcription determined by the ChIP and luciferase assay. Interestingly, EVI1 and ESR1 share common regulatory targets as indicated by the analysis of ChIP-Seq data. EVI1 and ESR1 collaborate in the regulation of some estrogen receptor-regulated genes. Furthermore, EVI1 drives tumor aggressiveness partially by regulating estrogen signaling. Estrogen enhances the proliferation, invasion and xenograft growth of ovarian cancer cells. Importantly, estrogen can rescue the inhibition of proliferation, invasion and xenograft growth induced by silencing EVI1. These findings suggest that EVI1 functions as a novel regulator of the estrogen signaling network in ovarian cancer.

Abstract
AIMS Because serous cystadenoma (SCA) does not usually require excision, it is critical to distinguish it from differential diagnoses which do, especially neuroendocrine tumour (NET). The gold standard for diagnosing SCA is assessment of endoscopic ultrasound-guided fine needle aspiration/biopsy (EUS-FNAB) material. Inhibin immunohistochemistry aids this assessment, but such positivity is not absolutely sensitive or specific to SCA. The following is the largest known study of SCA EUS-FNAB specimens and the first to compare four potential SCA immunomarkers between themselves and inhibin, compared against NET. METHODS AND RESULTS Immunohistochemistry for calponin, mucin 6 (MUC6), glucose transporter 1 (GLUT1) and vascular endothelial growth factor A (VEGFA) was performed on 30 EUS-FNAB and three resection specimens of SCA and 32 EUS-FNAB specimens of NET. GLUT1 and VEGFA were suboptimal as diagnostic immunomarkers of SCA, being expressed by 10 and 44% of NETs, respectively. Further, their expression by cellular constituents of blood which often contaminate EUS-FNAB specimens hampered identification of neoplastic cells, especially in hypocellular samples. While 19% of NETs showed nuclear MUC6 positivity, cytoplasmic expression of the protein showed 100% specificity and sensitivity as an SCA marker. However, assessing MUC6 in EUS-FNAB specimens must also consider the protein's focal expression in physiological pancreatic, gastric or duodenal tissues, which can contaminate these specimens. Calponin was less sensitive (71% versus 100%) but more specific (100% versus 91%) than inhibin, although easier to assess in EUS-FNAB specimens than MUC6. CONCLUSIONS Of the four potential immunomarkers of SCA suggested by the existing literature, calponin and MUC6 are useful complementary studies to inhibin for application to EUS-FNAB specimens.

Abstract
INTRODUCTION Determining the risk of malignancy in a pancreatic cyst (PC) is a clinical and diagnostic challenge. Monoclonal antibody (mAb) Das-1 test was shown to have high sensitivity, specificity, and accuracy in detecting high-risk (HR) cysts. Das-1 mAb test detects HR mucinous cysts with high-grade dysplasia (HGD), invasive carcinoma, and/or intestinal-type epithelium. Correlation of mAb Das-1 testing of PC fluids with cytomorphologic findings has not been evaluated. MATERIALS AND METHODS We correlated cytology with mAb Das-1 test results and resection histology in 26 PCs. There were 18 intraductal papillary mucinous neoplasms (IPMN), 1 intraductal oncocytic papillary neoplasm (IOPN), 4 mucinous cystic neoplasms (MCN), 2 serous cystadenomas, and 1 cystic pancreatic neuroendocrine tumor (PanNET). HR cysts included cysts with high-grade atypia on cytology or HGD on histology, invasive carcinoma, IOPNs, and cystic PanNETs. Intestinal type IPMNs were also HR cysts on histology. RESULTS In 17 cases (65.38%), cytology and mAb Das-1 test correlated with histology. There were 2 (7.69%) mAb Das-1 test negative HR PCs diagnosed by cytology. Five (19.23%) mAb Das-1 test positive HR PCs had mucin only or cells with low-grade dysplasia on cytology. Two mAb Das-1 test positive HR PCs had nondiagnostic cytology. HR IOPN and cystic PanNET were not detected by mAb Das-1 test. CONCLUSION The mAb Das-1 is a sensitive and specific biomarker for detecting HR mucinous PCs. Adding cytology to mAb Das-1 testing improves the sensitivity for the detection of nonmucinous HR PC. Together, cytology with mAb Das-1 testing is more accurate than either one alone.

Abstract
The subtypes of serous ovarian tumors (SOTs), including benign serous cystadenoma, serous borderline tumor (SBT), low-grade serous ovarian carcinoma (LGSC), and high-grade serous ovarian carcinoma (HGSC), remain poorly understood. Herein, we aimed to characterize the cell adhesion molecule 1 (CADM1)/signal transducer and activator of transcription 3 (STAT3)/human epidermal growth factor receptor 2 (HER2) axis and identify its clinical significance in patients with serous cystadenoma, SBT, LGSC, and HGSC.The immunohistochemical expression of CADM1, HER2, and STAT3 was assessed in 180 SOT specimens, and its association with clinical data was determined.High levels of CADM1 expression were detected in 100% of serous cystadenomas and 83.33% of SBTs, while a loss of CADM1 expression was observed in 44% of LGSCs and 72.5% of HGSCs. Relative to the levels in benign cystadenomas and SBTs, higher levels of HER2 and STAT3 expression were observed in LGSCs and aggressive HGSCs. Furthermore, the expression profile of the CADM1/HER2/STAT3 axis was significantly associated with histologic type, International Federation of Gynecology and Obstetrics stage, and lymph node metastasis in patients with SOT.Our study identified the changes in the CADM1/HER2/STAT3 axis that were closely associated with the clinical behavior of SOTs. These molecular data may provide new insights into SOT carcinogenesis and aid in the diagnosis and treatment of patients with SOT.

Abstract
Recent studies have shown that the expression of ENPP1 is related to differentiation, death, dissemination and chemosensitivity of tumor cells. So far, there is no research in ovarian carcinoma. This study aimed at exploring the role of ENPP1 gene in ovarian carcinoma, the relationship with prognostic indicators and chemotherapy resistance, and investigates the possibility of molecular targeted therapy. The expression of ENPP1 in 41 normal ovarian epithelial tissues, 97 ovarian serous cystadenoma and 103 HGSOC tissues was detected by IHC. In ovarian cancer tissues and ovarian cancer cell lines, mRNA and protein expression of ENPP1 was determined by qRT-PCR and Western blot. The ENPP1 expression was knockdowned by siRNA. Cell proliferation was measured with the BrdU Cell Proliferation ELISA. Cell migration and invasion were detected by Wound-Healing, Transwell migration and Matrigel invasion assay. Caspase 3 activity was determined by the CaspACE. The expression of EMT markers such as E-cadherin, N-cadherin, and Vimentin was measured, and the expression of PCNA and MMP9 was also be detected. The results showed that the expression of ENPP1 was significantly increased in high-grade ovarian serous carcinoma, the number of strong expression was 85.4% (22.3%+63.1%) and only 1.03% (1.03%+0.0%) in serous cystadenoma, but no in normal ovarian epithelium (P< 0.05). And the stronger the expression of ENPP1, the later the FIGO stage and the poorer differentiation of cells (P = 0.001 or <0.001, respectively). However, no correlation was found between the expression of ENPP1 and chemosensitivity. ENPP1 was also highly expressed in ovarian cancer tissues and in epithelial ovarian cancer cell lines (A2780, CaoV3, OVCAR3, SKOV3 and 3ao). After down-regulation of ENPP1 expression by RNA interference, the cell proliferation, migration and invasion of ovarian cancer cell decreased significantly, the expression of apoptosis related gene caspase 3 increased significantly, while the expression of PCNA and MMP9 was significantly down regulated. In addition, EMT biological characteristics of A2780 and SKOV3 cells were also inhibited. In summary, the increased expression of ENPP1 may be related to the occurrence of HGSOC, and indicate that the disease progresses rapidly and the prognosis is poor. ENPP1 may be considered as a potential molecular therapeutic target.

Abstract
PURPOSE Gene expression-based molecular subtypes of high-grade serous tubo-ovarian cancer (HGSOC), demonstrated across multiple studies, may provide improved stratification for molecularly targeted trials. However, evaluation of clinical utility has been hindered by nonstandardized methods, which are not applicable in a clinical setting. We sought to generate a clinical grade minimal gene set assay for classification of individual tumor specimens into HGSOC subtypes and confirm previously reported subtype-associated features. EXPERIMENTAL DESIGN Adopting two independent approaches, we derived and internally validated algorithms for subtype prediction using published gene expression data from 1,650 tumors. We applied resulting models to NanoString data on 3,829 HGSOCs from the Ovarian Tumor Tissue Analysis consortium. We further developed, confirmed, and validated a reduced, minimal gene set predictor, with methods suitable for a single-patient setting. RESULTS Gene expression data were used to derive the predictor of high-grade serous ovarian carcinoma molecular subtype (PrOTYPE) assay. We established a de facto standard as a consensus of two parallel approaches. PrOTYPE subtypes are significantly associated with age, stage, residual disease, tumor-infiltrating lymphocytes, and outcome. The locked-down clinical grade PrOTYPE test includes a model with 55 genes that predicted gene expression subtype with >95% accuracy that was maintained in all analytic and biological validations. CONCLUSIONS We validated the PrOTYPE assay following the Institute of Medicine guidelines for the development of omics-based tests. This fully defined and locked-down clinical grade assay will enable trial design with molecular subtype stratification and allow for objective assessment of the predictive value of HGSOC molecular subtypes in precision medicine applications.See related commentary by McMullen et al., p. 5271.

Abstract
Malignant abdominal fluid (ascites) frequently develops in women with advanced high-grade serous ovarian cancer (HGSOC) and is associated with drug resistance and a poor prognosis1. To comprehensively characterize the HGSOC ascites ecosystem, we used single-cell RNA sequencing to profile ~11,000 cells from 22 ascites specimens from 11 patients with HGSOC. We found significant inter-patient variability in the composition and functional programs of ascites cells, including immunomodulatory fibroblast sub-populations and dichotomous macrophage populations. We found that the previously described immunoreactive and mesenchymal subtypes of HGSOC, which have prognostic implications, reflect the abundance of immune infiltrates and fibroblasts rather than distinct subsets of malignant cells2. Malignant cell variability was partly explained by heterogeneous copy number alteration patterns or expression of a stemness program. Malignant cells shared expression of inflammatory programs that were largely recapitulated in single-cell RNA sequencing of ~35,000 cells from additionally collected samples, including three ascites, two primary HGSOC tumors and three patient ascites-derived xenograft models. Inhibition of the JAK/STAT pathway, which was expressed in both malignant cells and cancer-associated fibroblasts, had potent anti-tumor activity in primary short-term cultures and patient-derived xenograft models. Our work contributes to resolving the HSGOC landscape3-5 and provides a resource for the development of novel therapeutic approaches.

Abstract
OBJECTIVE Cancer patient-derived organoids (PDOs) grow as three dimensional (3D) structures in the presence of extracellular matrix and have been found to represent the original tumor's genetic complexity. In addition, PDOs can be grown and subjected to drug sensitivity testing in a shorter time course and with lesser expense than patient-derived xenograft models. Many patients with recurrent ovarian cancer develop malignant effusions that become refractory to chemotherapy. Since these same patients often present for palliative aspiration of ascites or pleural effusions, there is a potential opportunity to obtain tumor specimens in the form of multicellular spheroids (MCS) present in malignant effusion fluids. Our objective was to develop a short duration culture of MCS from ovarian cancer malignant effusions in conditions selected to support organoid growth and use them as a platform for empirical drug sensitivity testing. METHODS In this study, malignant effusion specimens were collected from patients with high-grade serous ovarian carcinoma (HGSOC). MCS were recovered and subjected to culture conditions designed to support organoid growth. In a subset of specimens, RNA-sequencing was performed at two time points during the short-term culture to determine changes in transcriptome in response to culture conditions. Organoid induction was also characterized in these specimens using Ki67 staining and histologic analysis. Drug sensitivity testing was performed on all specimens. RESULTS Our model describes organoids formed within days of primary culture, which can recapitulate the histological features of malignant ascites fluid and can be expanded for at least 6 days. RNA-seq analysis of four patient specimens showed that within 6 days of culture, there was significant up-regulation of genes related to cellular proliferation, epithelial-mesenchymal transition, and KRAS signaling pathways. Drug sensitivity testing identified several agents with therapeutic potential. CONCLUSIONS Short duration organoid culture of MCS from HGSOC malignant effusions can be used as a platform for empiric drug sensitivity testing. These ex vivo models may be helpful in screening new or existing therapeutic agents prior to individualized treatment options.

Abstract
Pancreatic serous cystic neoplasms (SCNs), such as serous cystadenoma (SCA), are generally recognized as benign because malignant counterparts of SCNs have been extremely rare. In clinical practice, pancreatic cystic neoplasms diagnosed as SCNs have been managed by conservative observation, as long as the patients remained asymptomatic. We herein report a case of metachronous ductal adenocarcinoma that was discovered during long-term follow-up of SCN and review the related literature. To our knowledge, this was the first reported case of the local presence of ductal adenocarcinoma adjacent to SCA that was preoperatively diagnosed by endoscopic ultrasound-guided fine-needle aspiration.

Abstract
PURPOSE Cystic tumors of the pancreas are increasingly common lesions. Unlike mucinous cystic tumors, serous cystadenomas are benign lesions and do not pose a risk of cancer. Often seen in women in the 6th and 8th decades, they are rarely seen in younger women or in male patients. Serous cystadenomas do not require surgical treatment unless they produce symptoms due to compression. Sometimes they may be misdiagnosed as cystic neuroendocrine tumors and resected because of the contrast enhancement on contrast enhanced cross-sectional studies. The purpose of this article is a translational analysis of why a cystic tumor enhances. MATERIAL AND METHODS The preoperative T2 HASTE, fat-suppressed T2 Turbo Spin Echo sequences, magnetic resonance cholangiopancreatography, diffusion weighted images, ex-vivo high-resolution T2 HASTE images of the post-operative pathologic specimen and immunohistochemical analysis with vascular marker CD31 were compared in a 58-yearold male patient with a pancreatic corpus microcystic serous cystadenoma. RESULTS The nodular lesion is observed as fluid signal in T2 weighted sequences and enhancing in postcontrast series. Exvivo high-resolution MRI has also revealed cysts with millimetric different sizes and septations within the lesion. Evaluation with the CD31 vascular marker showed that fibrous septa between the cysts were dense vascular and stained. CONCLUSION We show here that microcystic serous cystadenomas have intense vascularity of their septations that enhance in cross-sectional studies, especially when the cyst diameter is smaller. KEY WORDS CD31, Microcystic, MRI, Serous cystadenoma.

Abstract
Pancreatic serous cystadenoma (SCA) is a benign neoplastic lesion with a distinctive gross and microscopic appearance consisting of numerous thin-walled cysts lined by uniform epithelial cells with clear cytoplasm and small nuclei. The vast majority of serous cystadenomas are benign. Pancreatic SCA has rarely been reported in association with other pancreatic lesions. We present a challenging case in which a cystic and solid pancreatic mass was identified on imaging studies. FNA was performed and showed clusters of atypical cells with significant nuclear pleomorphism (>4:1), disorganized, overlapping nuclei, and prominent nucleoli. The FNA diagnosis was positive for malignancy, consistent with adenocarcinoma. The patient underwent neoadjuvant therapy and pancreaticoduodenectomy. Final pathology showed a serous cystadenoma associated with small foci of high-grade PanIN. The lack of invasive adenocarcinoma in the resection specimen was most likely due to complete response of the tumor to neoadjuvant chemoradiation therapy, but it is also possible that only high-grade PanIN was present initially. To our knowledge, this is the first reported case of SCA and high grade PanIN/PDAC that was assessed by FNA. We discuss the cytologic differential diagnosis and how to avoid potential pitfalls highlighted by this case.

Abstract
Large-scale genomic studies have detailed the molecular landscape of tumors from patients with high-grade serous ovarian cancers (HGSC) who underwent primary debulking surgery and correlated the identified subgroups to survival. In recent years, there is increased use of neoadjuvant chemotherapy (NACT) for patients with HGSC and while abundant data exist for patients who underwent primary debulking, little data are available on the cancer cells remaining after NACT that could lead to recurrences. We aimed to analyze gene expression profiles of NACT-treated HGSC tumor samples, and correlate them to treatment response and outcome. Tumor samples were collected from patients with stage III or IV HGSC (NACT cohort, N = 57) at the time of surgery and diagnosis (biopsy samples N = 8). Tumor content was validated by histologic examination and bioinformatics. Gene expression analysis was performed using a tailored NanoString-based assay, while sequencing was performed using MiSeq. A cross-validated survival classifier revealed patient clusters with either a "Better" or "Worse" prognostic outcome. The association with overall survival remained significant after controlling for clinical variables, and differential gene expression, gene set enrichment analyses, and the appropriate survival models were used to assess the associations between alterations in gene expression in cancer cells remaining after NACT and outcome. Pathway-based analysis of the differentially expressed genes revealed comparatively high levels of cell cycle and DNA repair gene expression in the poor outcome group. IMPLICATIONS: Our work suggests mRNA expression patterns in key genes following NACT may reflect response to treatment and outcome in patient with HGSC.

Abstract
Macrocystic serous cystadenoma (MSC) of the pancreas is a rare benign neoplasm with varied imaging appearances. We describe an intriguing case of a surgically resected and histologically proven giant MSC, developed in the pararenal space. Ultrasonography (US) revealed a large, oligocystic mass around the lower pole of right kidney. Like US, computed tomography, and magnetic resonance imaging were unable to detect the origin of the lesion, which was only verified at surgical exploration. A bizarre finding was the unusual location of the pancreatic tumor growing seemingly apart from the pancreas itself, with no obvious connection to it.

Abstract
Low-grade serous neoplasia of the gynecologic tract includes benign (serous cystadenomas), borderline, and malignant lesions (low-grade serous carcinoma). Classification of these lesions relies on rigorous attention to several pathologic features that determine the prognosis and the need for adjuvant therapy. Risk stratification of serous borderline tumor behavior based on histologic findings and criteria for low-grade serous carcinoma are the primary focus of this article, including the redesignation of invasive implants of serous borderline tumor as low-grade serous carcinoma based on the similar survival rates. The molecular underpinnings of these tumors are also discussed, including their potential for prognostication.

Abstract
Borderline ovarian tumors (BOTs) represent particular challenge for diagnosis and clinical management as they are characterized with the features of both benign cystadenomas and malignant carcinomas. The aim of our study was to investigate histomorphological and immunohistochemical characteristics of ovarian serous-papillary borderline tumors, compared to serous cystadenomas and low- and high-grade serous carcinomas. Altogether, 80 formalin fixed and paraffin embedded tissue specimens, distributed in four groups, including serous cystadenoma (group I), serous BOTs (group II), Low (group III) and high (group IV) grade serous carcinomas, were investigated by standard immunohistochemistry, using antibodies against CK7 CK20, WT1, Vimentin, CDX2, CEA, ER, cyclin D1, BCL2, E-cadherin, calretinin, СA125, Ki67, P53. Study results showed, that ovarian serous BOTs are characterized with slightly increase proliferative potential compared to benign cystadenomas, whilst apoptotic potential is retained with the difference from malignant serous carcinomas. p53 mutation is not present, as well as the expression of Vimentin. Overall, ovarian serous BOTs are characterized with highly variable immunohistochemical phenotype and the use of multiple immunohistochemical markers are recommended for the differential diagnosis from low grade serous carcinomas and benign cystadenomas.

Abstract
OBJECTIVE The rate of pancreatic lesions has increased in recent decades due to the widespread use of advanced imaging techniques. Nowadays, a significant proportion of cases are incidentally discovered in asymptomatic patients and cytology is an important tool for the diagnosis and multidisciplinary management of these cases. STUDY DESIGN In this study we retrospectively review the experience with pancreatic fine-needle aspiration cytology in the last 17 years at a single large tertiary hospital in Madrid, Spain. RESULTS Our results indicate that more than 60% of pancreatic malignant lesions are cytologically confirmed before surgery and 30% of the patients are asymptomatic. Despite this, we have noted that the total number of malignant lesions surgically resected in our hospital has basically remained unchanged over the years, because incidental diagnosis is not always synonymous with resectability and a substantial number of patients are already metastatic at the time of diagnosis. Our series also shows an increase in the number of neuroendocrine tumors, which now represent almost 20% of all cytological diagnoses at our hospital. The sensitivity in our series is 70% and the false negative rate remains 30%, despite sample quality control by experienced cytologists and standardized technical conditions. Fibrosis and necrosis are the 2 features of the primary tumor that significantly and negatively influence the accuracy of cytologic diagnosis. CONCLUSION We herein report our experience with cytologic diagnosis of pancreatic lesions in a single tertiary hospital. Our results confirm that cytology is a safe, reliable, and important tool for pancreatic lesion diagnosis and management.

Abstract
BACKGROUND The family of polypeptide N-acetylgalactosanimyltransferases (GalNAc-Ts) are important factors in glycosylation in carcinomas. The purpose of this study was to investigate the clinical significance of GalNAc-T6 and its correlation with the prognosis of epithelial ovarian carcinoma. MATERIALS AND METHODS A total of 150 patients with epithelial ovarian carcinoma were enrolled and the relationship between GalNAc-T6 expression by immunohistochemistry and long-term survival was evaluated. RESULTS The expression of GalNAc-T6 was positive in 57.6% (34/59) of those with serous carcinoma, 85.3% (29/34) in mucinous carcinoma, 15.6% (5/27) in clear cell carcinoma, and 44% (14/25) in endometrioid carcinoma. In a Kaplan-Meier analysis of patients with grade 1 or 2 serous carcinoma, the 10-year overall survival rates were 47.4% in the GalNAc-T6-positive and 9.1% in the GalNAc-T6-negative groups (p=0.047). CONCLUSION GalNAc-T6 expression in epithelial ovarian carcinoma was different according to pathological type. In low-grade serous carcinoma, GalNAc-T6 expression may contribute to improved long-term survival.

Abstract
AIM To investigate the reproducibility of the in vivo endoscopic ultrasound (EUS) - guided needle based confocal endomicroscopy (nCLE) image patterns in an ex vivo setting and compare these to surgical histopathology for characterizing pancreatic cystic lesions (PCLs).
METHODS In a prospective study evaluating EUS-nCLE for evaluation of PCLs, 10 subjects underwent an in vivo nCLE (AQ-Flex nCLE miniprobe; Cellvizio, MaunaKea, Paris, France) during EUS and ex vivo probe based CLE (pCLE) of the PCL (Gastroflex ultrahigh definition probe, Cellvizio) after surgical resection. Biopsies were obtained from ex vivo CLE-imaged areas for comparative histopathology. All subjects received intravenous fluorescein prior to EUS and pancreatic surgery for in vivo and ex vivo CLE imaging respectively.
RESULTS A total of 10 subjects (mean age 53 ± 12 years; 5 female) with a mean PCL size of 34.8 ± 14.3 mm were enrolled. Surgical histopathology confirmed 2 intraductal papillary mucinous neoplasms (IPMNs), 3 mucinous cystic neoplasms (MCNs), 2 cystic neuroendocrine tumors (cystic-NETs), 1 serous cystadenoma (SCA), and 2 squamous lined PCLs. Characteristic in vivo nCLE image patterns included papillary projections for IPMNs, horizon-type epithelial bands for MCNs, nests and trabeculae of cells for cystic-NETs, and a “fern pattern” of vascularity for SCA. Identical image patterns were observed during ex vivo pCLE imaging of the surgically resected PCLs. Both in vivo and ex vivo CLE imaging findings correlated with surgical histopathology.
CONCLUSION In vivo nCLE patterns are reproducible in ex vivo pCLE for all major neoplastic PCLs. These findings add further support the application of EUS-nCLE as an imaging biomarker in the diagnosis of PCLs.

Abstract
BACKGROUND Circulating epithelioid cells (CECs), also known as circulating tumor, circulating cancer, circulating epithelial, or circulating nonhematologic cells, are a prognostic factor in various malignancies that can be isolated via various protocols. In the current study, the authors analyzed the cytomorphologic characteristics of CECs isolated by size in a cohort of patients with benign and malignant pancreatic diseases to determine whether cytomorphological features could predict CEC origin. METHODS Blood samples were collected from 9 healthy controls and 171 patients with pancreatic disease who were presenting for surgical evaluation before treatment. Blood was processed with the ScreenCell size-based filtration device. Evaluable CECs were analyzed in a blinded fashion for cytomorphologic characteristics, including cellularity; nucleoli; nuclear size, irregularity, variability, and hyperchromasia; and nuclear-to-cytoplasmic ratio. Statistical differences between variables were analyzed via the Fisher exact test. RESULTS No CECs were identified among the 9 normal healthy controls. Of the 115 patients with CECs (positive or suspicious for), 25 had nonmalignant disease and 90 had malignancy. There were no significant differences in any of the cytologic criteria noted between groups divided by benign versus malignant, neoplastic versus nonneoplastic, or pancreatic ductal adenocarcinoma versus neuroendocrine tumor. CONCLUSIONS CECs were observed in patients with malignant and nonmalignant pancreatic disease, but not in healthy controls. There were no morphologic differences observed between cells from different pancreatic diseases, suggesting that numerous conditions may be associated with CECs in the circulation and that care must be taken not to overinterpret cells identified by cytomorphology as indicative of circulating tumor cells of pancreatic cancer. Additional studies are required to determine the origin and clinical significance of these cells. Cancer Cytopathol 2017;125:332-340. © 2017 American Cancer Society.

Abstract
BACKGROUND Pancreatic cystic lesions found in the literature are estimated between 2.6-19.6%. These neoplasms are almost exclusively benign tumors, and rarely become malignant. The aim of this paper was to report a feasible total pancreatectomy with portal resection in a giant pancreatic serous cystadenoma mimicking a malignant tumor. CASE PRESENTATION A healthy 52-year-old female patient presented to us with a giant pancreatic cyst with unknown preoperative diagnosis and a secondary dilatation of the Wirsung duct, and unclear vascular invasion. The imaging assessment was not conclusive for malignancy. Furthermore, it was decided to perform a total pancreatectomy with portal vein resection and splenectomy. The pathological findings revealed a microcystic serous cystadenoma of 10 cm with abundant myxoid stromal degeneration and focal papillary proliferation without atypia. CONCLUSION Unless the diagnosis of serous cystadenoma is certain, cystic tumors with inconclusive clinical and imaging features should be radically treated.

Abstract
OBJECTIVES Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. STUDY DESIGN A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA). RESULTS Fifty-one FNAs were identified. The average patient age was 59.9 years and 34 (67%) were female. Thirty-five (69%) of the SCAs were located in the body or tail of the pancreas. SCAs ranged in size from 1.3 to 8.0 cm (mean 4.9). On imaging, features suggestive of SCA were seen in 7 (14%) cases. The cytologic diagnoses were as follows: SCA in 5 (10%) cases, suspicious for mucin-producing neoplastic cyst in 4 (8%), pseudocyst in 4 (8%), and benign ductal and/or acinar epithelium, not otherwise specified in 24 (47%). Additionally, 14 (27%) cases were deemed nondiagnostic. CONCLUSIONS A cytopathologic diagnosis of SCA on FNA is extremely difficult. The salient cytomorphologic features for identifying SCAs included scant cellularity, a mostly clear background, absence of extracellular mucin, hemosiderin-laden macrophages, and loose fragments of cuboidal cells with a notable absence of necrosis, atypia, and mitoses.

Abstract
Hydatid disease (HD) is a commonly occurring zoonotic disease caused by tapeworms of the genus Echinococcus. It is endemic in many parts of the world and can involve almost any organ of the body. Although HD of the liver and lungs is quite common, ovarian involvement is rare. We present a case of a 24-year-old female patient who was diagnosed with multifocal hydatidosis involving the liver and bilateral ovaries on imaging. Postoperative histopathology confirmed the hydatid disease in the liver and one ovary. However, the cystic lesion in the other ovary turned out to be a borderline serous cystadenoma. This case highlights the limitation of imaging in differentiating between simple hydatid cysts and serous cystadenomas of the ovaries. Another point we learnt is that even in the presence of multifocal hydatidosis in endemic regions, serous cystadenoma needs to be considered in imaging differential diagnosis.

Abstract
Mixed serous neuroendocrine neoplasms are extremely rare tumors that are usually seen in female patients and are often associated with von Hippel Lindau (VHL) disease. We describe the case of a 38-year-old male who presented with complaints of anorexia, weight loss, and abdominal pain. CT abdomen showed a mass in the head of the pancreas, multiple small nodules in the body of pancreas, and bilateral adrenal masses. Fine needle aspiration cytology (FNAC) from the mass showed features of a neuroendocrine tumor, with many of the cells demonstrating abundant clear cytoplasm. Histopathological examination of the pancreaticoduodenectomy specimen showed a mixed serous neuroendocrine neoplasm with two components viz. serous cystadenoma and neuroendocrine tumor (NET) World Health Organization (WHO) grade 2. In addition, he was diagnosed to have bilateral pheochromocytomas and a paraganglioma. The synchronicity of these tumors suggested the possibility of VHL disease. Thus, identification of a NET with clear cells or of a mixed serous neuroendocrine neoplasm should raise suspicion of VHL disease. In a mixed tumor, FNAC may identify only one of the two components. Thorough processing of all pancreatic serous tumors for pathological examination is recommended, as NET may occur as a small nodule within the serous cystadenoma.

Abstract
Macrocystic serous cystadenoma is an unusual and essentially benign pancreatic tumor. Herein, we report on a 40-year-old woman diagnosed with macrocystic serous cystadenoma who presented with obstructive jaundice. A cystic lesion in the head and body of the pancreas was revealed by abdominal computed tomography. Intraoperative pancreatic cyst aspiration ruled out mucinous cystic neoplasm which has a malignant potential. The pancreatic cyst fluid cytology was basophilic amorph materials concluded as benign cystic lesion. Internal drainage was performed instead of pancreatic resection which showed good outcome. Biliary obstruction is a rare complication of serous cystadenoma. This case describes an unusual clinical presentation of macrocystic serous cystadenoma.

Abstract
OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCN's related mortality was 0.1% (n=1). CONCLUSIONS After a 3-year follow-up, clinical relevant symptoms occurred in a very small proportion of patients and size slowly increased in less than half. Surgical treatment should be proposed only for diagnosis remaining uncertain after complete workup, significant and related symptoms or exceptionally when exists concern with malignancy. This study supports an initial conservative management in the majority of patients with SCN. TRIAL REGISTRATION NUMBER IRB 00006477.

Abstract
BACKGROUND Different types of cancer exhibit abnormalities in cell cycle regulators. The murine double minute2(MDM2) cell cycle regulator is a protooncogene that negatively regulates the P53 tumour suppressor gene. Surface epithelial tumours constitute approximately two thirds of ovarian neoplasms. Each histologic type can be classified as benign, borderline and malignant. This study aimed to examine immunohistochemical expression of the MDM2 protein in ovarian serous and mucinous epithelial tumours (benign, borderline and malignant). MATERIALS AND METHODS This study included forty five ovarian tumours, subdivided into fifteen cystadenomas (5 serous and 10 mucinous), fifteen borderline tumours (11 serous and 4 mucinous) and fifteen cystadenocarcinomas (9 serous and 6 mucinous). Paraffin sections were stained with haematoxylin and eosin for histopathologic study, and with mouse monoclonal antiMDM2 antibody for immunohistochemistry. RESULTS MDM2 positivity was detected in 28.9% of the studied ovarian tumours. All benign tumours were negative and positivity was significantly higher in malignant than borderline tumours (P value of chisquare test =0.000). Significantly, all MDM2 positive mucinous tumours were malignant with no positive mucinous borderline tumours. Malignant tumours showed positive MDM2 expression in 83.3% of mucinous type and in 55.6% of serous type. Borderline serous tumours showed negative MDM2 in 72.7% of cases (P value of Z test =0.04). CONCLUSIONS Alterations in the expression of the cell cycle regulator (MDM2) occur early in the process of tumourigenesis in serous and mucinous ovarian tumours. We suggest that MDM2 may be used in those tumours as a marker for risk stratification and identification of cases with cancer development and progression. We recommend further studies on MDM2 immunohistochemistry, in conjunction with adjuvant methods as DNA ploidy and FISH gene amplification, focusing on the mucinous tumours and differentiating between the three tumour categories, benign, borderline and malignant.

Abstract
Serous cystadenoma (SC) is a benign pancreatic cystic tumor. Surgical resection is recommended for symptomatic forms, but laparoscopic fenestration of large symptomatic macrocystic SC was not yet described in the literature. In this study, 3 female patients underwent laparoscopic fenestration for macrocystic SC (12-14 cm). Diagnosis was established via magnetic resonance imaging and endoscopic ultrasound, with intra-cystic dosage of tumors markers (ACE and CA19-9) in 2 patients. All patients were symptomatic and operated on 15-60 mo after diagnosis. Radiological evaluation showed constant cyst growth. Patients were informed about this new surgical modality that can avoid pancreatic resection. The mean operative time was 103 min (70-150 min) with one conversion. The post-operative course was marked by a grade A pancreatic fistula in one patient and was uneventful in the other two. The hospital stay was 3, 10, and 18 d, respectively. The diagnosis of macrocystic SC was histologically-confirmed in all cases. At the last follow-up (13-26 mo), all patients were symptom-free, and radiological evaluation showed complete disappearance of the cyst. Laparoscopic fenestration, as opposed to resection, should be considered for large symptomatic macrocystic SC, thereby avoiding pancreatic resection morbidity and mortality.

Abstract
Incidental cystic lesions of the pancreas are often detected due to the increased use of cross-sectional imaging. Since mucinous cysts have a malignant potential, whereas pseudocysts and serous cystadenomas are benign, the distinction is of key clinical importance. Current recommendations advocate the use of multiple imaging modalities (CT/MRI/endoscopic US/endoscopic US & fine-needle aspiration) during evaluation and follow-up. This review describes the most frequent cystic lesions of the pancreas and suggests a simple investigation and treatment algorithm.

Abstract
OBJECTIVE To evaluate the value of intraoperative fine needle aspiration cytology (IFNAC) examination in the diagnosis of pancreatic lesions. METHODS The clinicopathological data of 491 patients with pancreatic lesions treated in our hospital from May 1998 to June 2013 were retrospectively analyzed. Their clinical features, IFNAC findings, pathological results after IFNAC examination and related complications were summarized. The factors affecting the aspiration biopsy accuracy were analyzed using logistic regression and multi factor analysis. RESULTS 491 patients with pancreatic lesions were examined by IFNAC. Among them, cancer cells were found in 434 cases (positive), and were not found in 57 cases (negative). Among the 310 cases who underwent surgical operation, postoperative pathology confirmed 209 cases of pancreatic ductal adenocarcinoma, 8 cases of pancreatic cystadenocarcinoma, 23 cases of solid pseudopapillary tumor of the pancreas, 15 cases of pancreatic neuroendocrine tumor, 14 cases of intraductal papillary mucinous tumor, 2 cases of primary pancreatic gastrointestinal stromal tumor, 17 cases of pancreatic serous cystadenoma, and 22 cases of chronic mass-forming type pancreatitis. The IFNAC test showed a sensitivity of 97.9% (425/434), and specificity of 89.5% (51/57). The IFNAC examination-related complications were pancreatic leakage in a total of 12 patients which were cured after treatment. No bleeding complication was observed. Logistic multivariate analysis showed that tumor size, cystic degeneration, lymph node metastasis and associated chronic pancreatitis are independent factors affecting the IFNAC examination of pancreatic carcinoma. CONCLUSIONS IFNAC examination has a high sensitivity and specificity, and with a good safety in clinical use. IFNAC can be used as a powerful tool for the diagnosis of pancreatic cancer, with a high clinical value in use. In the cytology-negative cases, cytology alone can not rule out the diagnosis of pancreatic cancer. Through repeated sampling and combined with intraoperative frozen section pathology can improve the diagnostic accuracy.

Abstract
Solid serous cystadenoma (SCA) of the pancreas is a rare type of pancreatic solid tumors. Postoperative pathological evaluation is of particular importance for distinguishing solid SCA of the pancreas from other pancreatic solid tumors. Here we present 2 cases of solid SCA of the pancreas, both preoperatively diagnosed with pancreatic neuroendocrine tumors. One case had positive OctreoScan test. Surgical resections were done for both cases. Postoperative immunohistochemistry assays were conducted with marker panels for SCA and 2 types of pancreatic solid tumors, which were neuroendocrine tumor (pNET) and solid pseudopapillary tumor (SPT). Two cases showed typical staining patterns for SCA markers. Notably, both cases showed positivity for 4 SPT markers (vimentin, β-catenin, α-1 antitrypsin, and α-1 antichymotrypsin). Emphasis should be paid to those 4 new markers for future pathological diagnosis of solid SCA of the pancreas.

Abstract
In 2009, Montgomery and Epstein coined the term "anastomosing hemangioma" for a newly described variant of capillary hemangioma with an unusual sinusoidal pattern, histologically mimicking angiosarcoma. The lesion was considered unique for genitourinary system with predilection to kidney but we found in the literature only 4 cases of this entity in ovaries. A 70-year-old woman presented with ultrasound visualized myometrial nodules and cystic formation of the right ovary, intraoperatively diagnosed as serous cystadenoma. Hysterectomy with bilateral adnexectomy was performed. The section of the ovary revealed a fortuitous finding in the cortex: circumscribed lesion, 7 mm in diameter, with mahogany brown, spongy appearance. Microscopic examination of H&E-stained slides manifested well-demarcated but un-encapsulated vascular proliferation, composed of tightly packed capillary-sized blood vessels with an anastomosing sinusoidal-like architecture and tortuous "feeding" and "draining" vessels of medium caliber. Endothelial lining featured only mild cytologic atypia and lack of mitotic figures. The lesion was surrounded by luteinized ovarian stroma. Immunohistochemical examination with CD34 highlighted endothelial cells; SMA--supporting stromal cells. The anastomosing hemangioma of the ovary with stromal luteinisation was diagnosed as accidental finding. The authors discuss morphological characteristics of anastomosing hemangioma and the unusual for menopausal women but quite often combination between this lesion in the ovary and stromal luteinisation.

Abstract
Incidental cystic lesions of the pancreas are often detected due to the increased use of cross-sectional imaging. Since mucinous cysts have a malignant potential, whereas pseudocysts and serous cystadenomas are benign, the distinction is of key clinical importance. Current recommendations advocate the use of multiple imaging modalities (CT/MRI/endoscopic US/endoscopic US & fine-needle aspiration) during evaluation and follow-up. This review describes the most frequent cystic lesions of the pancreas and suggests a simple investigation and treatment algorithm.

Abstract
OBJECTIVES To characterize the exact individual roles of gonadotropins on ovarian epithelial carcinogenesis, an earlier study showed that prohibitin was significantly up-regulated by luteinizing hormone (LH). To further clarify the role of prohibitin in ovarian carcinogenesis and its association with LH, herein we studied the expression of prohibitin in various ovarian tissues including different developmental stages of ovarian epithelial tumors. METHODS A total of 135 samples were studied by immunohistochemistry. These included benign ovarian cases with follicles, ovarian surface epithelia and ovarian epithelial inclusions (OEI) (n=30), serous cystadenoma (n=14), serous borderline tumor (n=12), serous carcinoma (n=20), mucinous cystadenoma (n=10), mucinous borderline tumor (n=10), mucinous carcinomas (n=10), endometrioid carcinomas (n=12), poorly/undifferentiated carcinomas (n=5), and fallopian tube (n=12). RESULTS Strong and diffuse staining of prohibitin was detected in luteinized ovarian stromal cells, follicular cells, fallopian tube, and OEI with serous differentiation. A significantly higher prohibitin expression in luteinized stromal cells than in non-luteinized stromal cells was observed (P<.01). Within the ovarian epithelium, the level of prohibitin expression was basically negative in ovarian surface epithelia, but highly expressed in OEI. However, compared to the level of prohibitin expression in OEI, it showed a trend of gradual loss from benign ovarian tumors, to borderline tumors and to carcinomas (P<.0001). Compared to the serous tumors, epithelial tumors with mucinous differentiation showed a significant lower level of prohibitin (P<.0001). An inverse correlation was noted between prohibitin expression and cancer grade. It is interesting to note that a high prohibitin expression level was seen in the fallopian tube, which is similar to OEI. CONCLUSIONS These data further suggest that prohibitin plays a tumor suppressing role, which is probably associated with LH mediated protection role against ovarian epithelial carcinoma. In addition to the tumor suppressive role of prohibitin, it also plays a role in cellular differentiation, which may be helpful to differentiate ovarian mucinous tumors from the tumors with serous differentiation in clinical settings. More importantly, our findings are supportive that the ovarian epithelial cancers, particularly the serous cancers including those precursors with serous differentiation are likely to be derived from fallopian tube instead of ovarian surface epithelia.

Abstract
Objective To examine single nucleotide polymorphism (SNPs) in MUC16 (CA125) and MUC1 (CA15.3) in relation to ovarian cancer risk and survival. Methods We genotyped germline variants of MUC16 (rs2547065, rs1559168, rs12984471, rs2121133) and MUC1 (rs2070803, rs4072037, rs1045253) using samples collected from 758 ovarian cancer cases and 788 controls enrolled in the New England Case-Control Study between 2003 and 2008. We calculated age-adjusted odds ratios (OR) and 95% confidence intervals (CIs) for disease risk using unconditional and polytomous logistic regression and hazard ratios (HR) for survival using Cox proportional hazard ratios. In a subset of cases, we compared log-normalized CA125 values by genotype using generalized linear models. Results Cases homozygous for the variant allele of MUC16 SNP, rs12984471, had poorer overall survival (log-rank p = 0.03) and higher CA125 levels, especially cases over age 65 (p = 0.01). For MUC1 SNP, rs4072037, women homozygous for the G variant had a non-significantly decreased risk for serous invasive types but elevated risk for serous borderline tumors, mucinous borderline and invasive tumors, and endometrioid tumors. Women with the variant allele of MUC16 SNP, rs2547065, especially those who were homozygous had an elevated risk for ovarian cancer; but this association was not confirmed in an independent dataset. Conclusion This targeted screen of seven polymorphisms of MUC16 and MUC1 genes failed to identify and confirm effects on ovarian cancer risk overall. However, there may be effects of MUC16 rs12984471 on survival and MUC1 rs4072037 on risk for histologic types of ovarian cancer other than invasive serous. Further study is warranted.

Abstract
Epithelial ovarian cancer is one of the most lethal gynecological malignant tumors despite improvement of the treatment. Recent molecular studies show that ovarian cancer is a heterogeneous disease which is reflected by different histologic types. These subtypes differ from their origin, pathogenesis and molecular alterations and can be divided in two major groups. The type I cancer (low grade) evolves from precursor lesions in a step-wise process. In contrast, the type II cancer (high grade) grows rapidly without any identifiable precursors. Among all subtypes is heterogeneity in the biological behavior which has implications in patient prognosis and treatment especially for individualized therapies in the future.

Abstract
Brenner tumor accounts for 1.5 to 2.5% of ovarian tumors. Nearly all are benign and 1% malignant. Less than twenty-five cases of borderline Brenner tumor have been reported worldwide. Our case is the first one related to a bilateral ovarian serous cystadenofibroma and endometrioid adenocarcinoma. This unusual case increases the limited data for borderline Brenner tumors.
