Abstract
This review focuses on the diagnostic, prognostic, and predictive molecular biomarkers in ovarian epithelial neoplasms in the context of their morphologic classifications. Currently, most clinically actionable molecular findings are reported in high-grade serous carcinomas; however, the data on less common tumor types are rapidly accelerating. Overall, the advances in genomic knowledge over the last decade highlight the significance of integrating molecular findings with morphology in ovarian epithelial tumors for a wide-range of clinical applications, from assistance in diagnosis to predicting response to therapy.

Abstract
This report describes 3 cases of ovarian tumors with unusual glandular proliferations co-expressing estrogen receptor and CDX-2 by immunohistochemistry set in cystadenofibromatous background. Targeted next-generation sequencing was performed on the cyst lining epithelium and glandular proliferations for all cases; CTNNB1 mutations were detected in the glandular proliferations of all neoplasms. The cyst lining of case 1 demonstrated a different CTNNB1 mutation from the matched glandular proliferation. No mutations were detected in the cyst lining from case 2. The cyst lining and glandular proliferation for case 3 harbored identical ATM and PIK3CA mutations with an additional CTNNB1 mutation in the glandular proliferation. To our knowledge, this is the first reported series of endometrioid proliferations with co-expression of estrogen receptor and CDX-2 in cystadenofibromatous background.

Abstract
The current study highlighted the ARID1A and SALL4 expression and described histopathologic and immunohistochemical features of ovarian seromucinous tumors (SMTs) including borderline tumors (SMBTs) and seromucinous carcinomas (SMC; namely as endometrioid carcinoma with mucinous differentiation according to WHO 2020 classification). The clinicopathological and immunohistochemical features of 38 SMTs were analyzed, including ARID1A, SALL4, estrogen receptor (ER), progesterone receptor (PR), TP53, keratin 7, keratin 20, CEA, CDX2, WT1, PAX2, and PAX8. SMCs and SMBTs comprised 68.4% (n = 26) and 31.6% (n = 12) of all SMTs, respectively, studied. The mean age of diagnosis was 47.4 years and 41.4 years, and the mean size was 9 cm and 7.45 cm for SMC and SMBT, respectively. There was endometriosis or endometriotic cyst in 61.5% of SMCs and 50% of SMBTs. Immunohistochemically, loss of ARID1A staining was observed in 15 (65.2%) of 26 SMCs, and 3 (33.3%) of the 12 SMBTs. Only one SMC showed focal SALL4 positivity. All SMTs were positive for ER, PR, PAX8, and keratin 7. SMTs were negative for WT1, keratin 20, CDX2, and CEA (negative in 66.7% to 92.3% of the cases). While all SMBTs and 24 (92.3%) of 26 SMCs exhibited “wild-type” TP53 staining, 2 (7.7%) SMCs, both were stage III, showed mutant type TP53 overexpression. We indicate there is a similarity between SMC and SMBT according to the immunohistochemical features. SMBTs are keratin 7, ER, PR positive tumors, and some of them have loss of ARID1A expression and are likely to develop in the background of endometriosis similar to SMC.

Abstract
STUDY OBJECTIVE To study the progression of benign ovarian lesions to mucinous borderline ovarian tumors (mBOTs); analyze the clinicopathologic features, diagnosis, and management of mBOTs in pediatric and adolescent girls; and provide a review of the literature on mBOTs in this population. DESIGN Retrospective chart review of female adolescents younger than 18 years diagnosed with mBOTs between July 2017 and February 2021. SETTING Yale New Haven Hospital, New Haven, Connecticut; and Yale New Haven Health Bridgeport Hospital, Bridgeport, Connecticut. PARTICIPANTS Three female patients diagnosed with mBOTs between ages 12 and 17 years. INTERVENTIONS None. MAIN OUTCOME MEASURES Clinical presentation, preoperative characteristics, surgical technique, histology, tumor stage, treatment, progression, outcome, and rate of recurrence. RESULTS Three adolescent patients were identified to have mBOTs. All three patients presented with a chief complaint of abdominal pain. One of the 3 patients was premenarchal at presentation. Two of the 3 patients were initially diagnosed with a mucinous cystadenoma and had recurrences of an ovarian cyst in the same ovary within 5 and 17 months, respectively. Pathology of the recurrent cyst was consistent with mBOT. Two of the 3 patients initially underwent cystectomy, and all ultimately had a unilateral salpingo-oophorectomy. Subsequent surveillance over 2 to 4 years found no evidence of disease recurrence. CONCLUSION mBOTs are rare in the pediatric and adolescent population and could arise from benign ovarian tumors.

Mutation Profiles of Ovarian Seromucinous Borderline Tumors in Japanese Patients. Curr Oncol 2022; 29:3658-3667. [PMID: 35621684 PMCID: PMC9139622 DOI: 10.3390/curroncol29050294] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 04/22/2022] [Accepted: 04/29/2022] [Indexed: 11/17/2022] Open
Abstract
Ovarian seromucinous tumors (SMBTs) are relatively rare, and their carcinogenesis is largely unknown. In this study, the molecular features of SMBTs in Japan are assessed. DNA was extracted from microdissected paraffin-embedded sections from 23 SMBT cases. Genetic mutations (KRAS, BRAF, PIK3CA, and ERBB2) were evaluated using Sanger sequencing. Immunohistochemistry for p53, ARID1A, and PTEN was also performed as a surrogate for the loss of functional mutations in these tumor suppressor genes. The prevalence of KRAS, BRAF, PIK3CA, and ERBB2 mutations was 4.3% (1/23), 8.6% (2/23), 8.6% (2/23), and 17.3% (4/23), respectively. Overexpression or loss of p53 expression occurred in 26% (6/23), loss of ARID1A expression in 4.3% (1/23), and none of the cases showed expression of PTEN loss. These findings suggest that KRAS/BRAF/PIK3CA and PTEN mutations are rare carcinogenic events in SMBTs. The high frequency of positive p53 staining and a low frequency of loss of ARID1A staining suggests that SMBT carcinogenesis may be related to the alteration of p53 rather than that of ARID1A. ERBB2 oncogenic mutations may play an important role in the tumorigenesis of Japanese SMBTs.

Oncological and reproductive outcomes after fertility-sparing surgery in patients with seromucinous borderline ovarian tumor: Results of a large retrospective study. Gynecol Oncol 2022; 165:446-452.

Abstract
OBJECTIVE To evaluate the oncological and reproductive outcomes in patients with seromucinous borderline ovarian tumors (SMBOT) treated with fertility-sparing surgery (FSS). METHODS We retrospectively reviewed the medical records of patients with SMBOT who underwent surgery between 2000 and 2019. A centralized histological review was performed and recurrence rates were compared between different surgical procedures. RESULTS A total of 105 patients fulfilled the inclusion criteria, of whom 65 underwent FSS and 40 were treated with radical surgery (RS). Fourteen patients had recurrent disease after a median follow-up time of 59.6 months (range: 22.1-256.8 months). All but one relapsed with SMBOT. There was no significant difference in disease-free survival (DFS) between the two groups (P = 0.141). Multivariate analysis showed that only bilateral involvement was associated with increased recurrence (P = 0.008). In the subgroup of patients treated with conservative surgery, there was no significant difference in DFS with regard to surgical procedures (ovarian cystectomy vs salpingo-oophorectomy, P = 0.487). Of the 12 patients in the FSS group who developed recurrence, 11 underwent a second round of FSS and all remained alive with no evidence of disease at the end of follow-up. Of 20 patients desiring pregnancy, 16 patients were successful and resulted in 17 term deliveries. CONCLUSIONS FSS is feasible for young patients who wish to preserve their fertility. Patients initially treated with ovarian cystectomy may be managed by close surveillance if post-operative imaging are negative. Repeat FSS remains a valuable alternative for young patients with recurrent SMBOT after thorough communication.

Abstract
A subset of ovarian mucinous tumors demonstrates müllerian-type epithelium, with such lesions variably designated "endocervical-like" and seromucinous since their popularization based on a report of borderline examples in 1989. While müllerian mucinous borderline tumors and carcinomas have been highlighted in the literature, there has been minimal attention given to benign müllerian mucinous tumors, particularly müllerian mucinous cystadenomas. Given the paucity of literature describing the features of müllerian mucinous cystadenomas/cystadenofibromas, diagnostic difficulties may arise when papillary features are present and in cases that show a subtle transition from endometriosis. We thus reviewed 25 cases of müllerian mucinous cystadenoma/cystadenofibroma to highlight the notable characteristics of this entity, including gross, cytologic, and architectural features that aid in the distinction from müllerian mucinous borderline tumors as well as, rarely, metastatic tumors. The patients ranged in age from 26 to 85 yr old. Bilateral ovarian involvement was frequent (40%). The ovaries ranged from 2.3 to 26 cm in greatest dimension. Most were multicystic (18 cases) and contained tenacious mucoid material (14 cases). All cases demonstrated predominantly columnar mucinous epithelium with abundant pale-pink cytoplasm. A minor component of ciliated and endometrioid epithelium was seen in 15 and 2 cases, respectively. Broad papillary formations were frequently encountered (9 cases) as was epithelial papillary tufting comprising <10% of the tumor (6 cases). Endometriosis was present in 9 cases, with a transition from endometriosis to mucinous epithelium noted in 8 cases. This series highlights the morphologic features of a relatively uncommon, benign, endometriosis-associated ovarian tumor that may be confused with a müllerian mucinous borderline tumor or bland metastatic mucinous tumors. It also provides an argument for the terminology "müllerian mucinous cystadenoma" or "cystadenofibroma" rather than "seromucinous cystadenoma" due to the frequent association with endometriosis as well as the dominant mucinous epithelium.

Abstract
Seromucinous tumors belong to a group of ovarian epithelial tumors. They were originally described as tumors characterized by Müllerian endocervical differentiation. Molecular genetic studies have indicated these tumors as endometriosis-associated tumors due to the presence of ARID1 gene mutations. However, the histogenesis of these neoplasms is still unstudied.

Abstract
The molecular underpinnings of seromucinous borderline tumor (SMBT) - an uncommon ovarian epithelial neoplasm characterized by association with endometriosis, frequent bilateral ovarian involvement, and occasional progression to invasive carcinoma - remain poorly understood. Here, we sought to comprehensively characterize the mutational landscape of SMBT and elucidate the clonal relationship between bilateral ovarian SMBTs. We also compared the mutational profiles between SMBTs and concurrent invasive carcinomas. Formalin-fixed, paraffin-embedded tissue specimens were retrieved from 28 patients diagnosed with SMBT. Massively parallel sequencing of 409 cancer-related genes was conducted to identify somatic mutations in 33 SMBT samples and four concurrent invasive carcinoma specimens. TERT promoter mutations were assessed by Sanger sequencing, whereas immunohistochemistry was used as a surrogate tool for detecting deletions or epigenetic silencing of relevant tumor suppressor genes. Twenty-six (92.9%) of the 28 patients were diagnosed with stage I SMBTs. Seven (25%) cases showed bilateral ovarian involvement and 13 (46%) had concomitant endometriosis. Concurrent ovarian carcinomas were identified in three patients, whereas one case had a synchronous endometrial carcinoma. Somatic mutations in the KRAS, PIK3CA, and ARID1A genes were identified in 100, 60.7, and 14.3% of SMBT samples, respectively. In contrast, TERT promoter mutations and DNA mismatch repair deficiencies were absent. Sequencing of paired specimens from patients with bilateral SMBT revealed the presence of at least two shared somatic mutations, suggestive of a clonal relationship. Similarly, we identified shared somatic mutations between SMBT samples and concurrent ovarian carcinoma specimens. Taken together, these findings demonstrated a distinct mutational landscape of SMBT in which (1) KRAS is invariably mutated, (2) PIK3CA is frequently mutated, and (3) TERT promoter mutations and DNA mismatch repair deficiencies are absent. Our findings represent the first extensive characterization of this rare ovarian neoplasm, with potential implications for disease classification and molecular diagnostics.

Abstract
AIMS To report a series of benign ovarian seromucinous neoplasms, an uncommon and hitherto poorly described category of tumours included in the current 2014 World Health Organisation classification of tumours of the female reproductive organs. METHODS AND RESULTS We report the clinicopathological features of a series of 22 benign ovarian seromucinous neoplasms (cystadenomas and adenofibromas or admixtures). The neoplasms occurred in patients aged 32-83 years (mean = 62, median = 65.5) and involved the left ovary (n = 14), the right ovary (n = 6) or both ovaries (n = 2). There was a common association with endometrioid elements (endometrioid differentiation within the cystadenoma/adenofibroma and/or endometriosis) and other endometriosis-associated neoplasms. CONCLUSIONS We speculate that some of these represent benign ovarian endometrioid neoplasms with foci of mucinous and/or serous differentiation, while others represent true mixed neoplasms.

Abstract
PURPOSE Decidualized endometriomas (DEs) and seromucinous borderline tumors (SMBTs) exhibit similar MR findings including markedly hyperintense mural nodules within endometriotic cysts on T2-weighted images. The present study aimed to assess the efficacy of MR imaging for differentiating between DEs and SMBTs of the ovary. MATERIALS AND METHODS MR images of 8 DEs and 14 SMBTs were retrospectively assessed and compared according to pathologies. RESULTS With regard to quantitative assessments of mural nodules, the number and signal intensity ratios (SIRs) on T1-weighted images were significantly greater in DEs than in SMBTs (11.0 ± 8.4 vs. 4.3 ± 4.1, p < 0.05 and 2.36 ± 0.56 vs. 1.49 ± 0.27, p < 0.01, respectively), whereas the height was significantly lower in DEs than in SMBTs (4.5 ± 1.4 mm vs. 21.9 ± 11.4 mm, p < 0.01). However, there were no significant differences between DEs and SMBTs in the SIRs on T2-weighted images, SIRs on diffusion-weighted images, and apparent diffusion coefficient values. With regard to qualitative assessments of mural nodules, the lobulated margin, pedunculated configuration, and T2 hypointense core were significantly more frequent in SMBTs than in DEs (71% vs. 0%, p < 0.01; 86% vs. 0%, p < 0.01; and 43% vs. 0%, p < 0.05, respectively). CONCLUSION The number, height, SIRs on T1-weighted images, lobulated margin, pedunculated configuration, and T2 hypointense core of mural nodules within endometriotic cysts were useful MR findings for differentiating DEs from SMBTs.

Abstract
Objective Only few studies have focused on tumor markers used in the preoperative diagnosis of endometriosis-related ovarian neoplasms, and previous studies have only assessed serum CA125 levels. This study investigated the significance of preoperative tumor markers and clinical characteristics in distinguishing endometriosis-related ovarian neoplasms from ovarian endometrioma. Methods A case-control study was conducted on 283 women who were diagnosed with confirmed pathology with endometriosis-related ovarian neoplasms (n=21) and ovarian endometrioma (n=262) at a single institution from April 2008 to April 2018. The serum CA125, CA19–9, carcinoembryogenic antigen (CEA), sialyl Lewis-x antigen (SLX), and lactate dehydrogenase (LDH) levels, age, tumor size, and the presence of mural nodule of the patients were analyzed. Results Patients with endometriosis-related ovarian neoplasms were more likely to be older (48 (range, 26–81) vs 39 (range, 22–68) years, P<0.001), have higher levels of CA19–9 (42 vs 19 U/mL, P=0.013), CEA (1.3 vs 0.84 ng/mL, P=0.007), SLX (41 vs 33 U/mL, P=0.050), and LDH (189 vs 166 U/mL, P<0.001) and larger tumor size (79 vs 55 mm, P=0.001), and present with mural nodule (85.7 vs 4.5 %, P<0.001) than those with ovarian endometrioma. The CA125 levels did not significantly differ between the two groups. The area under the curve for each factor was as follows: CA19-9 level, 0.672 (95% CI 0.52 to 0.83; P=0.013); CEA level, 0.725 (95% CI 0.58 to 0.87; P=0.007); SLX level, 0.670 (95% CI 0.53 to 0.84; P=0.050); LDH level, 0.800 (95% CI 0.70 to 0.90; P<0.001); age, 0.775 (95% CI 0.65 to 0.90; P<0.001); and tumor size, 0.709 (95% CI 0.56 to 0.86; P=0.001). Age was a better marker than CA19-9, CEA, and SLX levels according to the receiver operating characteristic curve analysis. The optimal cut-off values for age and tumor size were 47 years and 80 mm, respectively. Conclusions The assessment of serum CA19–9, CEA, SLX, and LDH levels may be a useful tool in the preoperative evaluation to differentiate between endometriosis-related ovarian neoplasms and ovarian endometrioma.

Abstract
Ovarian seromucinous tumors were introduced in the 2014 World Health Organization (WHO) classification as one of the seven types of ovarian epithelial tumors. They are characterized by frequent association with endometriosis and bilaterality, microscopic appearance of papillary architecture, and admixture of a variety of müllerian-type epithelium. They are considered to be endometriosis-related ovarian neoplasms, along with endometrioid and clear cell tumors; recent molecular studies suggest this particular tumor is a variant of endometrioid tumor. Discrepancies in nomenclature, definition, and morphology of seromucinous tumors appear to be a source of confusion, for both clinicians and general surgicalpathologists. This review summarizes the clinicopathological features of benign, borderline, and malignant seromucinous tumors, as well as controversies regarding these tumors.

Abstract
This article reviews the most relevant pathological and molecular features of ovarian tumours that are associated with endometriosis. Endometriosis is a common condition, affecting 5-15% of all women, and it has been estimated that 0.5-1% of cases are complicated by neoplasia. The most common malignant tumours in this setting are endometrioid adenocarcinoma and clear cell adenocarcinoma, each accounting for approximately 10% of ovarian carcinomas in Western countries. A minority of cases are associated with Lynch syndrome. These carcinomas are often confined to the ovaries at presentation in which case they have relatively favourable outcomes. However, high-stage tumours, particularly clear cell carcinomas, generally have a poor prognosis and this partly reflects relative resistance to current treatment. Histological diagnosis is straightforward in the majority of cases but some variants, for example endometrioid carcinomas with sex cord-like appearances or oxyphil cells, may create diagnostic difficulty. Similarly, clear cell carcinomas can show a range of architectural and cytological patterns that overlap with other tumours, both primary and metastatic, involving the ovaries. Endometriosis-associated borderline tumours are less common, and they often show mixed patterns of differentiation (seromucinous tumours). Atypical endometriosis may represent an intermediate step in neoplastic progression and some of these lesions demonstrate immunohistological and molecular alterations similar to those observed in endometriosis-related tumours. ARID1A mutations are relatively common in all of these tumours, but each has additional characteristic molecular alterations which are likely to be of increasing clinical relevance as targeted therapies are developed. Less is known of the pathogenesis of rarer endometriosis-associated ovarian tumours including endometrioid stromal sarcoma, mesodermal (Müllerian) adenosarcoma, and carcinosarcoma. This article also briefly reviews the issue of synchronous endometrioid carcinomas of the endometrium and the ovary, including the most recent developments on pathogenesis.

Abstract
PURPOSE Seromucinous borderline tumor (SMBT) is a newly categorized ovarian tumor in the 2014 revised World Health Organization (WHO) classification. SMBT is similar to serous borderline tumor (SBT) on MRI reflecting their pathological findings. This study was conducted to demonstrate the usefulness of MRI findings and quantitative values for differentiating SMBT from SBT. METHODS This retrospective study examined 23 lesions (20 patients) from SMBT and 26 lesions (22 patients) from SBT. The following quantitative values were evaluated using receiver-operating characteristics analysis: overall and solid portion sizes, intracystic fluid signal intensity (SI) ratio compared with skeletal muscle on T1weighted image (T1WI) and T2weighted image (T2WI), contrast enhancement (CE) ratio, and mean and minimum apparent diffusion coefficient values of the solid portion. Two radiologists evaluated the prevalence of MRI finding characteristics of SMBT and SBT. The SI of the intracystic fluid on T1WI and T2WI and the association with endometriosis were evaluated visually. RESULTS The CE ratio was significantly higher in SBT (P = 0.007). It achieved the highest area under the curve (AUC) (0.739). The fluid SI ratio on T1WI was higher in SMBT (P = 0.036, AUC = 0.676). Exophytic growth of the solid portion was observed only in SBT (P = 0.011). Intracystic fluid SI of SMBT was higher on T1WI and lower on T2WI in visual evaluation (P = 0.008 and 0.007, respectively). Findings suggesting endometriosis were observed more frequently in SMBT patients (P = 0.019). CONCLUSION Higher CE ratio of the solid portion and exophytic growth were findings suggesting SBT. Higher intracystic fluid SI on T1WI and lower SI on T2WI suggested SMBT. MRI findings suggesting endometriosis favored the diagnosis of SMBT.

Abstract
Borderline ovarian tumors (BOT) are uncommon but not rare epithelial ovarian neoplasms, intermediate between benign and malignant categories. Since BOT were first identified >40 years ago, they have inspired controversies disproportionate to their incidence. This review discusses diagnostic criteria for the histologic subtypes of BOT, highlighting areas of diagnostic challenges, ongoing controversies, and changes in terminology implemented by the recent 2014 WHO Classification of Tumours of the Female Genital Organs. Emerging knowledge supports the notion that subtypes of borderline ovarian tumors comprise distinct biologic, pathogenetic, and molecular entities, precluding a single unifying concept for BOT. Serous borderline tumors (SBT) share molecular and genetic alterations with low-grade serous carcinomas and can present at higher stages with peritoneal implants and/or lymph node involvement, which validates their borderline malignant potential. All other (non-serous) subtypes of BOT commonly present at stage I confined to the ovary(ies) and are associated with overall survival approaching that of the general population. An important change in the WHO 2014 classification is the new terminology of non-invasive implants associated with SBT, as any invasive foci (previously called “invasive implants”) are now in line with their biological behavior considered peritoneal low-grade serous carcinoma (LGSC). The controversy regarding the terminology of non-serous borderline tumors, called by some pathologists “atypical proliferative tumor” in view of their largely benign behavior, has not been resolved. The concepts of intraepithelial carcinoma and microinvasion may evolve in further studies, as their presence appears to have no prognostic impact and is subject to considerable inter-observer variability.

Abstract
OBJECTIVES To evaluate the diagnostic performance of quantitative values and MRI findings for differentiating seromucinous borderline tumours (SMBTs) from endometriosis-related malignant ovarian tumours (MT). METHODS This retrospective study examined 19 lesions from SMBT and 84 lesions from MT. The following quantitative values were evaluated using receiver-operating characteristic analysis: overall and solid portion sizes, fluid signal intensity (SI), degree of contrast-enhancement, and mean and minimum apparent diffusion coefficient (ADC) values of the solid portion. Two radiologists independently evaluated four MRI findings characteristic of SMBT, fluid SI on the T1-weighted image and SI of the solid portion on diffusion-weighted image. The diagnostic values of these findings and interobserver agreement were assessed. RESULTS For diagnosing SMBT, the mean ADC value of the solid portion showed the greatest area under the curve (0.860) (cut-off value: 1.31 × 10-3 mm2/s, sensitivity: 1.00, specificity: 0.61). The T2-weighted image (T2WI) high SI solid portion was the most useful finding, with high specificity and interobserver agreement (sensitivity, 0.58; specificity, 0.95-0.96, kappa = 0.96), followed by T2WI low SI core (sensitivity, 0.48-0.63; specificity, 0.98, kappa = 0.68). CONCLUSION Mean ADC values of the solid portion, T2WI high SI solid portion, and T2WI low SI core were useful for differentiating SMBT from MT. KEY POINTS • SMBT is a newly categorised ovarian tumour often associated with endometriosis. • Differentiation of SMBT from endometriosis-related malignant ovarian tumour is clinically important. • Diagnostic performances of quantitative values and MRI findings were evaluated. • Mean ADC value of the solid portion was the most useful value. • "T2WI high SI solid portion" was the most useful MRI finding.

Abstract
Seromucinous borderline tumors are typically confined to the ovaries and rarely relapse after surgery. We report the case of a woman with a seromucinous borderline tumor with peritoneal implant at the Douglas pouch, who was affected by a recurrent tumor at the vaginal stump 2 years and 6 months after the primary surgery. The recurrent lesion was detected by vaginal cytology. Histology of the recurrent lesion showed perineural infiltration, and progression to low-grade adenocarcinoma was suggested. After the second surgery, vaginal cytology showed that the tumor cells remained positive. At postoperative follow-ups of ovarian borderline tumors, an examination of the specific region where recurrence is likely to occur can contribute to the early detection of tumor relapse. Diagn.

Abstract
BACKGROUND Mucinous and serous borderline ovarian tumours (mBOTs and sBOTs) are controversial diseases. OBJECTIVES With this systematic review we aim to evaluate the different high-risk histopathological features and recurrence rates. SEARCH STRATEGY The PubMed database was searched using two terms: {serous AND [(borderline) OR (low malignant potential)] AND ovarian AND tumour} and {mucinous AND [(borderline) OR (low malignant potential)] AND ovarian AND tumour}. SELECTION CRITERIA Cohorts of either sBOT or mBOT, peer-reviewed, retrospective, or prospective. DATA COLLECTION AND ANALYSIS Lethal recurrence data for micropapillary patterns (MPs), microinvasion, non-invasive and invasive implants, and intraepithelial carcinoma (IECA). The primary measure of effect was the odds ratio of lethal recurrence reduction. RESULTS Data from patients in 42 studies including 4414 sBOTs and 12 studies including 894 mBOTs were pooled. Of these, 53.3% presented early-stage typical sBOTs, 24.4% presented with MPs, 22.3% presented with microinvasion, 34.4% presented with non-invasive implants, and 7.3% presented with invasive implants. The pooled lethal recurrence rates were, respectively: 18.3, 16.8, 10.7, 16.2, and 33.8%. Patients with MPs were more likely to suffer lethal recurrence when compared with high-stage sBOTs (odds ratio, OR 0.501; P = 0.003), whereas the trend in microinvasive sBOTs did not reach statistical significance. Regarding mBOTs, 61.6% presented with early-stage typical mBOTs, 19.6% presented with microinvasion, 34.8% presented with IECA, and six patients presented with non-invasive implants; none presented with invasive implants. The lethal recurrence rates were, respectively: 3.6, 0, 3.7, and 0%. CONCLUSION Micropapillary patterns (MPs) showed a higher risk for lethal recurrence when compared with high-stage sBOTs. Regarding mBOTs, IECA and microinvasion do not play a role in the lethal recurrence rate. TWEETABLE ABSTRACT Micropapillary pattern confirmed as high-risk in BOT. IECA and microinvasion don't play a role in mucinous BOT.

Abstract
Endometriosis is a common gynecological disease affecting 6%–10% of women of reproductive age and is characterized by the presence of endometrial-like tissue in localizations outside of the uterine cavity as, e.g., endometriotic ovarian cysts. Mainly, two epithelial ovarian carcinoma subtypes, the ovarian clear cell carcinomas (OCCC) and the endometrioid ovarian carcinomas (EnOC), have been molecularly and epidemiologically linked to endometriosis. Mutations in the gene encoding the AT-rich interacting domain containing protein 1A (ARID1A) have been found to occur in high frequency in OCCC and EnOC. The majority of these mutations lead to a loss of expression of the ARID1A protein, which is a subunit of the SWI/SNF chromatin remodeling complex and considered as a bona fide tumor suppressor. ARID1A mutations frequently co-occur with mutations, leading to an activation of the phosphatidylinositol 3-kinase (PI3K)/AKT pathway, such as mutations in PIK3CA encoding the catalytic subunit, p110α, of PI3K. In combination with recent functional observations, these findings strongly suggest cooperating mechanisms between the two pathways. The occurrence of ARID1A mutations and alterations in the PI3K/AKT pathway in endometriosis and endometriosis-associated ovarian carcinomas, as well as the possible functional and clinical implications are discussed in this review.

Abstract
The ultimate goal of defining cancer specific precursors is to facilitate early detection and intervention before the development of invasive malignancy. Unlike other malignancies involving the female genital tract such as cervical or endometrial carcinomas, precursor lesions of ovarian carcinomas have not been well characterised, resulting in a failure to develop effective screening programs. Recent clinicopathological and molecular studies have provided new insight into the origin and pathogenesis of ovarian carcinomas. It has been shown that ovarian cancer is comprised of different tumour types differing not only in morphology, but also in pathogenesis, molecular alterations and clinical progression. A dualistic model of ovarian carcinogenesis has been proposed. Type I tumours which include low grade serous, low grade endometrioid, clear cell, mucinous carcinomas and Brenner tumours, are generally indolent and tend to be genetically stable, although clear cell carcinoma would probably belong to an intermediate category. They demonstrate a step-wise progression from a benign precursor such as a benign to borderline tumour or endometriosis and are characterised by genetic aberrations targeting specific cell signalling pathways. Type II tumours comprise high grade serous, high grade endometrioid, and undifferentiated carcinomas as well as malignant mixed mesodermal tumours. They are clinically aggressive and exhibit high genetic instability with frequent p53 mutations. Mounting evidence suggests that many high grade serous carcinomas originate from the epithelium of the distal fallopian tube, and that serous tubal intraepithelial carcinoma (STIC) represents the putative precursor of these neoplasms. Low grade serous carcinomas arise via transformation of benign and borderline serous tumours, thought to be derived from inclusion cysts originating from the ovarian surface or tubal epithelium. Recently it has been suggested that papillary tubal hyperplasia may be a putative precursor lesion for serous borderline tumours. Both endometrioid and clear cell carcinomas develop from endometriosis, via alterations affecting different genetic pathways. The origin of mucinous and transitional cell neoplasms is not well characterised, although new data suggest a possible origin from transitional cell nests present at the tubal-mesothelial junction. Likewise, the pathogenesis of carcinosarcomas is also not well established because of their rarity but there is accumulating evidence that the carcinomatous component determines the course of the disease and gives rise to the malignant mesenchymal component. This review discusses recent developments in the pathogenesis of ovarian carcinoma, with particular emphasis on the putative precursor lesions that give rise to the major histological subtypes. Recognition of these lesions is not only important in improving the understanding of ovarian carcinogenesis, but it will also influence our approach to prevent, detect and treat these tumours.

Abstract
In 2006, under the auspices of The Spanish Research Group for Ovarian Cancer (Spanish initials GEICO), the first "Treatment Guidelines in Ovarian Cancer" were developed and then published in Clinical and Translational Oncology by Poveda Velasco et al. (Clin Transl Oncol 9(5):308-316, 2007). Almost 6 years have elapsed and over this time, we have seen some important developments in the treatment of ovarian cancer. Significant changes were also introduced after the GCIG-sponsored 4th Consensus Conference on Ovarian Cancer by Stuart et al. (Int J Gynecol Cancer 21:750-755, 2011). So we decided to update the treatment guidelines in ovarian cancer and, with this objective, a group of investigators of the GEICO group met in February 2012. This study summarizes the presentations, discussions and evidence that were reviewed during the meeting and during further discussions of the manuscript.

Abstract
Endometriosis-related ovarian neoplasms (ERONs) are a unique group of tumors as they are associated with endometriosis, especially endometriosis presenting as an ovarian endometriotic cyst (endometrioma). ERONs include clear cell carcinoma, endometrioid carcinoma, and seromucinous borderline tumor. A growing body of evidence from both clinicopathologic and molecular studies suggests that most, if not all, ERONs develop from endometriotic cyst epithelium through different stages of tumor progression. The endometriotic cyst contains abundant iron-induced reactive oxygen species that are thought to be mutagenic, and chronic exposure of cystic epithelium to this microenvironment facilitates the accumulation of somatic mutations that ultimately result in tumor development. Molecular analyses of ERONs, including genome-wide screens, have identified several molecular genetic alterations that lead to aberrant activation or inactivation of pathways involving ARID1A, PI3K, Wnt, and PP2A. Among all molecular genetic changes identified to date, inactivating mutations of the ARID1A tumor suppressor gene are the most common in ERON. Understanding the molecular changes and pathogenesis involved in the development of ERON is fundamental for future translational studies aimed at designing new diagnostic tests for early detection and identifying critical molecular features for targeted therapeutics.

Abstract
The association between endometriosis and malignant transformation has often been described in the medical literature. A search was conducted between 1966 and 2010 through the English language literature (online Medline PubMed database) using the keywords endometriosis combined with malignant transformation. The search revealed an increase in reports describing endometriosis and malignancy. Approximately 1.0% of women with endometriosis have lesions that undergo malignant transformation. The malignant processes that are associated with endometriosis may be classified into three groups: i) epithelial ovarian cancers (endometrioid adenocarcinoma and clear cell carcinoma), ii) other Müllerian-type tumors, including Müllerian-type mucinous borderline tumor and serous borderline tumor and iii) sarcomas such as adenosarcoma and endometrial stromal sarcoma in the female pelvic cavity. Persistent oxidative stress induced by endometriosis-dependent hemorrhage may be associated with carcinogenesis. In conclusion, the malignant transformation of endometriosis has multiple pathways of development and may share a common pathogenic mechanism; iron-induced oxidative stress derived from repeated hemorrhage.

"Piling up" clear cells in müllerian-type mucinous and mixed cell-type borderline tumor do not represent concomitant clear cell neoplasms. Hum Pathol 2012; 43:1618-26.

Abstract
The nature of "piling up" proliferation of clear cells in müllerian mucinous/mixed borderline tumor has not been well characterized. The purpose of this study was to clarify whether or not such clear cells represent concomitant clear cell neoplasms. First, we carefully reviewed hematoxylin and eosin slides taken from 139 ovarian tumors diagnosed as clear cell carcinoma (112 cases) and müllerian mucinous/mixed borderline tumor (27 cases) to clarify (1) the frequency of piling-up clear cells in müllerian mucinous/mixed borderline tumor and (2) the frequency of the coexistence of typical clear cell carcinoma and müllerian mucinous/mixed borderline tumor. Second, we investigated the immunohistochemical expression of estrogen receptor, hepatocyte nuclear factor-1β, and glypican-3 in proliferating clear cells in both tumors. We identified piling-up clear cells in 56% of müllerian mucinous/mixed borderline tumors. Such clear cells lacked the severe nuclear atypia, complex branching, and dense hyalinized cores of typical clear cell carcinoma. We did not find coexistence of typical clear cell carcinoma and müllerian mucinous/mixed borderline tumor in any tumors. Piling-up clear cells and endocervical-like mucinous cells were positive for estrogen receptor but negative for hepatocyte nuclear factor-1β and glypican-3. Most clear cell carcinomas showed a hepatocyte nuclear factor-1β-positive/estrogen receptor-negative immunophenotype, and about half of them were glypican-3 positive. In conclusion, piling-up clear cells in müllerian mucinous/mixed borderline tumor do not represent concomitant clear cell neoplasms because clear cell carcinoma and müllerian mucinous/mixed borderline tumor hardly ever coexist and because such clear cells in both tumors are immunophenotypically distinct.

KRAS mutations in ovarian low-grade endometrioid adenocarcinoma: association with concurrent endometriosis. Hum Pathol 2012; 43:1177-83.

Abstract
The association between ovarian endometrioid adenocarcinoma and endometriosis is well established. However, not all endometrioid adenocarcinomas are directly related to endometriosis, and it has been suggested that there may be clinicopathologic differences between endometriosis-positive and endometriosis-negative tumors. Molecular alterations in endometrioid adenocarcinoma include KRAS and BRAF mutations, but the incidence of these abnormalities in previous reports has been highly variable (0%-36% and 0%-24%, respectively). This may be explained by relatively small sample sizes in earlier studies but could also reflect difficulties in accurately classifying high-grade ovarian malignancies. In the current study, we investigated KRAS and BRAF mutations in 78 low-grade (FIGO grade 1 and 2) endometrioid adenocarcinomas and compared the results with the presence of endometriosis in the tumor-associated ovary and/or in other pelvic sites. KRAS mutations were identified in 12 (29%) of 42 endometriosis-associated endometrioid adenocarcinomas with satisfactory analysis but in only 1 (3%) of 29 tumors in which endometriosis was not identified. BRAF mutation was identified only in a single endometriosis-associated case. These findings support the hypothesis that endometriosis-associated and independent endometrioid adenocarcinoma may develop via different molecular pathways and that KRAS mutations have an important role only in the former tumors. In contrast, BRAF mutations do not appear to have a significant role in either endometrioid adenocarcinoma subgroup. This may be relevant to future targeted therapies in patients with high-stage or recurrent disease and indicate that histopathologists should carefully examine endometrioid adenocarcinoma specimens, including nonneoplastic tissues, for the presence of endometriosis.

Abstract
Endometriosis is a chronic disease that affects millions of reproductive-age women. Despite the destructive and invasive nature of endometrioses, most cases are perpetually benign or eventually regress; however, atypical endometriosis is a precursor lesion and can lead to certain types of ovarian cancer. Endometriosis induced inflammation and auto- and paracrine production of sex steroid hormones contribute to ovarian tumorigenesis. These changes provide microenvironment necessary to accumulate enough genetic alterations for endometriosis associated malignant transformation. It takes years for endometriosis to undergo the pathophysiological progression that begins with atypical epithelial proliferation (atypical endometriosis and metaplasia), and then is followed by the formation of well-defined borderline tumors, and finally culminates in fully malignant ovarian cancer. This study is a review of the natural history of endometriosis and the role of microenvironments that favor the accumulation of genetic alterations and endometriosis-associated ovarian cancer progression.

Abstract
Exome sequencing of ovarian clear-cell carcinoma has identified somatic mutations in PPP2R1A, a subunit of protein phosphatase 2A. The present study was performed to determine the frequency of PPP2R1A mutations in exon 5, which harbors previously reported mutation hot spots, and adjacent exon 6, in 209 ovarian and 56 uterine tumors of various histologic subtypes. PPP2R1A mutations were demonstrated in 10 of 110 type I ovarian tumors (9.1%) including low-grade serous, low-grade endometrioid, clear-cell, and mucinous carcinomas. In contrast, none of 71 type II ovarian (high-grade serous) carcinomas exhibited PPP2R1A mutations. Moreover, PPP2R1A mutations were observed in 2 of 30 type I uterine (endometrioid) carcinomas (6.7%) and 5 of 26 type II uterine (serous) carcinomas (19.2%). Of the 18 mutations, 13 affected the R182 or 183, and there were 5 novel mutations including 3 involving S256, 1 involving W257, and 1 involving P179. All mutations were located in the α-helix repeats near the interface between the A subunit and the regulatory B subunit of the enzyme complex. These data provide new evidence that PPP2R1A somatic mutations occur in certain types of uterine and ovarian neoplastic lesions, especially uterine serous carcinomas, and suggest that mutation of PPP2R1A may participate in the pathogenesis of ovarian type I and uterine type II carcinomas.
