Abstract
Endometriosis is a benign, common, but controversial disease due to its enigmatic etiopathogenesis and biological behavior. Recent studies suggest multiple genetic, and environmental factors may affect its onset and development. Genomic analysis revealed the presence of cancer-associated gene mutations, which may reflect the neoplastic aspect of endometriosis. The management has changed dramatically with the development of fertility-preserving, minimally invasive therapies. Diagnostic strategies based on these recent basic and clinical findings are reviewed. With a focus on the presentation of clinical cases, we discuss the imaging manifestations of endometriomas, deep endometriosis, less common site and rare site endometriosis, various complications, endometriosis-associated tumor-like lesions, and malignant transformation, with pathophysiologic conditions.

Abstract
Clear cell borderline ovarian tumor (CCBOT) is quite rare, and only a few cases of CCBOT have been reported. Unlike most borderline ovarian tumors, CCBOTs appear solid because they are almost always pathologically adenofibromatous. Herein, we report the MRI findings of a CCBOT discovered in a 22-year-old female.

Abstract
The treatment of high-grade serous ovarian cancer and high-grade endometrioid ovarian cancer has seen significant improvements in recent years, with BRCA1/2 and homologous recombination status guiding a personalized approach which has resulted in improved patient outcomes. However, for other epithelial ovarian cancer subtypes, first-line treatment remains unchanged from the platinum-paclitaxel trials of the early 2000s. In this review, we explore novel therapeutic approaches being adopted in the treatment of clear cell, mucinous, carcinosarcoma and low-grade serous ovarian cancer and the biological rational behind them. We discuss why such disparities exist, the challenges faced in conducting dedicated trials in these rarer histologies and look towards new approaches being adopted to overcome them.

Abstract
Some patients with advanced clear-cell ovarian cancer (CCOC) respond to immunotherapy; however, little is known about the tumor microenvironment (TME) of this relatively rare disease. Here, we describe a comprehensive quantitative and topographical analysis of biopsies from 45 patients, 9 with Federation Internationale des Gynaecologistes et Obstetristes (FIGO) stage I/II (early CCOC) and 36 with FIGO stage III/IV (advanced CCOC). We investigated 14 immune cell phenotype markers, PD-1 and ligands, and collagen structure and texture. We interrogated a microarray data set from a second cohort of 29 patients and compared the TMEs of ARID1A-wildtype (ARID1Awt) versus ARID1A-mutant (ARID1Amut) disease. We found significant variations in immune cell frequency and phenotype, checkpoint expression, and collagen matrix between the malignant cell area (MCA), leading edge (LE), and stroma. The MCA had the largest population of CD138+ plasma cells, the LE had more CD20+ B cells and T cells, whereas the stroma had more mast cells and αSMA+ fibroblasts. PD-L2 was expressed predominantly on malignant cells and was the dominant PD-1 ligand. Compared with early CCOC, advanced-stage disease had significantly more fibroblasts and a more complex collagen matrix, with microarray analysis indicating "TGFβ remodeling of the extracellular matrix" as the most significantly enriched pathway. Data showed significant differences in immune cell populations, collagen matrix, and cytokine expression between ARID1Awt and ARID1Amut CCOC, which may reflect different paths of tumorigenesis and the relationship to endometriosis. Increased infiltration of CD8+ T cells within the MCA and CD4+ T cells at the LE and stroma significantly associated with decreased overall survival.

Abstract
BACKGROUND Clear cell borderline ovarian tumor (CCBOT) is one of the rarest subtypes of borderline ovarian malignancies. The aim of this study was to determine the prognosis of a series of CCBOT. PATIENTS AND METHODS A retrospective review of patients with CCBOT treated or referred to our institutions. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS Nineteen patients were identified. Median age was 62 (range 36-83) years. Four patients underwent a conservative surgery and 14 a bilateral salpingo-oophorectomy +/- hysterectomy (unknown in 1 case). One patient had bilateral tumor, and all cases were stage-I disease. All CCBOTs showed an adenofibromatous pattern. Stromal microinvasion was observed in seven cases and intraepithelial carcinoma in two cases. Endometriosis was histologically associated in one case. The median follow-up was 76 (range 6-231) months. No recurrence occurred. Two patients died of intercurrent disease. CONCLUSIONS Peritoneal staging procedures should always be associated, but restaging surgery could be omitted if there was no suspicious lesion in the peritoneum during initial surgery, since all patients reported had stage-I disease. Fertility-sparing surgery appears to be a safe alternative in young patients. Synchronous endometrial disorders with atypia are infrequent. Prognosis is generally excellent, and long-term risk of recurrence is low. The two recurrences described in literature occurred in stage-IC diseases, highlighting the importance of avoiding perioperative rupture.

Abstract
The aim of the present study was to examine the clinical outcome of ovarian clear cell borderline tumor (CCBT) through pathological review for cases with clear cell carcinoma (CCC) and CCBT between 1984 and 2015 who received surgery at the National Defense Medical College Hospital using 2020 World Health Organization (WHO) criteria. In addition to the definition of CCBT in 2020 WHO criteria, clear cell with atypia of the glandular epithelium without fibromatous component was added to the diagnostic criteria of CCBT. Two cases with CCBT were identified through review in the current study. There were no cases that changed from the initial CCBT diagnosis that were included in the current study. Case 1 was a 43-year-old woman who received total hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy. Pathologically, cysts were lined by cuboidal, hobnail and clear cells with eosinophilic cytoplasm and moderate nuclear atypia without the fibromatous component. These cells were adjacent to atypical endometriosis and non-atypical endometriosis, and the patient was diagnosed with CCBT. She exhibited no evidence of the disease for 37 months following surgery. Case 2 was a 42-year-old woman who received left salpingo-oophorectomy, partial omentectomy and pelvic lymphadenectomy. The tumor exhibited a cyst (80 mm) and nodular component. Pathologically, the tumor cells were lined by hobnail cells with mild atypia and eosinophilic cytoplasm without the fibromatous component. This patient was diagnosed with CCBT and exhibited no evidence of disease for 20 months following surgery. CCBT without fibromatous component is a rare and non-aggressive histological subtype. Additionally, regardless of fibromatous component, CCBT was able to be diagnosed.

Abstract
Ovarian clear cell carcinoma (OCCC) is a special pathological type of epithelial ovarian carcinoma (EOC) and has a high prevalence in Asia without specific molecular subtype classification. Endometriosis is a recognized precancerous lesion that carries 3-fold increased risk of OCCC. Ovarian endometrioid carcinoma, which also originates from endometriosis, shares several features with OCCC, including platinum resistance and younger age at diagnosis. Patients with OCCC have about a 2.5 to 4 times greater risk of having a venous thromboembolism (VTE) compared with other EOC, and OCCC tends to metastasize through lymphatic vesicular and peritoneal spread as opposed to hematogenous metastasis. There is only mild elevation of the conventional biomarker CA125. Staging surgery or optimal cytoreduction combined with chemotherapy is a common therapeutic strategy for OCCC. However, platinum resistance commonly portends a poor prognosis, so novel treatments are urgently needed. Targeted therapy and immunotherapy are currently being studied, including PARP, EZH2, and ATR inhibitors combined with the synthetic lethality of ARID1A-dificiency, and MAPK/PI3K/HER2, VEGF/bFGF/PDGF, HNF1β, and PD-1/PD-L1 inhibitors. Advanced stage, suboptimal cytoreduction, platinum resistance, lymph node metastasis, and VTE are major prognostic predictors for OCCC. We focus on update pathogenesis, diagnostic methods and therapeutic approaches to provide future directions for clinical diagnosis and treatment of OCCC.

Abstract
AIM The scar of cesarean section (CS) is the most common site of abdominal wall endometriosis (AWE), whose tumor degeneration has been reported in an increasing number of cases; the most frequent histological type is clear cell carcinoma (CCC). METHODS We conducted a systematic research of the literature, collecting data regarding the evidence on tumor degeneration from AWE after CS. Moreover, we reported a case of clear cell borderline tumor (CCBT) originating from AWE. RESULTS We included data of 37 patients with diagnosis of CCC. The average time between the last CS and the diagnosis of CCC was around 15 years. Overall, 26.0% and 73.9% patients received exclusive local abdominal resection of the lesion and additional surgery, respectively. Lymph nodes involvement was detected in 26.0 % patients and adjuvant chemotherapy was administered in 52.0 % cases. During follow-up period, 15.2% patients died of disease, 32.6% had no evidence of disease, and 17.4% recurred. We diagnosed a CCBT arose in a patients with AWE and a personal history of several surgical procedures for endometriosis, a CS and a subsequent transverse laparotomy. We performed an open bilateral ovariectomy and a large excision of the endometriotic abdominal lesion. CONCLUSION Tumor degeneration from AWE seems to be a real occurrence with an increasing number of events. Considering the lack of risk factors and diagnostic instruments for tumor degeneration, the removal of AWE localization could be advisable, even though there was long average time between the trigger surgery and the tumor finding.

Abstract
BACKGROUND Endometriosis is complex, but identifying the novel biomarkers, inflammatory molecules, and genetic links holds the key to the enhanced detection, prediction and treatment of both endometriosis and endometriosis related malignant neoplasia. Here we review the literature relating to the specific molecular mechanism(s) mediating tumorigenesis arising within endometriosis. METHODS Guidance (e.g. Cochrane) and published studies were identified. The Published studies were identified through PubMed using the systematic review methods filter, and the authors' topic knowledge. These data were reviewed to identify key and relevant articles to create a comprehensive review article to explore the molecular fingerprint associated with in endometriosis-driven tumorigenesis. RESULTS An important focus is the link between C3aR1, PGR, ER1, SOX-17 and other relevant gene expression profiles and endometriosis-driven tumorigenesis. Further studies should also focus on the combined use of CA-125 with HE-4, and the role for OVA1/MIA as clinically relevant diagnostic biomarkers in the prediction of endometriosis-driven tumorigenesis. CONCLUSIONS Elucidating endometriosis' molecular fingerprint is to understand the molecular mechanisms that drive the endometriosis-associated malignant phenotype. A better understanding of the predictive roles of these genes and the value of the biomarker proteins will allow for the derivation of unique molecular treatment algorithms to better serve our patients.

Abstract
Clear cell carcinoma (CCC) is a well-known aggressive histological type of carcinoma, predominantly seen in ovary and endometrium. However, CCC arising in abdominal wall is a very rare event. We report a case of a 48-year-old woman with an abdominal wall mass at her cesarean section (c-section) scar, which increased in size and became painful in the last months. Radiology revealed a 7 cm mass in the right inferior rectus muscle sheath, suggestive of endometriosis. An irregular, firm mass was resected, densely adherent to the rectus muscle and pubic bone. Frozen section revealed a multicystic lesion with minimal cytologic atypia, and a benign cystic neoplasm was favored. However, permanent sections showed marked nuclear atypia, hobnail morphology, and areas of infiltrative growth within fibrous stroma. No benign endometrial glands were found, although fibrosis and hemorrhage were present. Napsin-A, racemase, and PAX-8 were positive, consistent with CCC, likely arising within a c-section endometriosis focus. Although CCC usually presents with moderate to marked nuclear atypia, it can be mild and, especially in cases with a predominant cystic pattern, create diagnostic difficulties. An endometriosis-associated malignancy should be considered in the differential with any enlarging nodule or increasing pain within an abdominal wall scar.

Abstract
Clear cell Mullerian-type adenocarcinoma of the testis is an exceedingly rare entity, and its histogenesis and clinical behavior are still poorly understood. We discuss three cases of clear cell carcinoma of the testis, compiled from a review of the literature and our personal experience. Microscopically, the tumors closely resembled clear cell carcinoma of the ovary, displaying papillae lined by clear cells with areas of hobnailing. The reported immunophenotypic features were also similar to that of ovarian tumors, as positivity for epithelial markers (CK7, CAM5.2, AE1/AE3, EMA) and Mullerian markers (PAX8, CA125) with negativity for estrogen and progesterone receptors have been observed. The pathogenesis of testicular clear cell carcinoma is still poorly understood, with reported cases displaying evidence of both mesothelial and Mullerian origin. In addition, molecular characterization of testicular clear cell carcinomas has yet to be accomplished; however, studies performed on ovarian clear cell carcinomas may provide insight to the origin, biologic behavior, and potential therapeutic modalities for this obscure, aggressive malignancy.

Abstract
Research has strongly suggested that the features of endometriosis serve as a precursor lesion of ovarian cancer. Cisplatin (CDDP) is the preferred drug against these cancer types. The present study investigated the effects of CDDP on surgically induced endometriosis in a rat model. Endometriosis was surgically induced by the autologous transplantation of endometrial tissue. A total of 36 model rats were randomly divided into three groups. The rats in Group 1 (control group, n=12) received no medication. The rats in Group 2 (n=12) and Group 3 (n=12) were administered 35 mg/m2 CDDP and 70 mg/m2 CDDP, respectively, every four days. All rats were treated for a total of 24 days. The growth and histologic scores of the implants were calculated. The expression of protein markers, including vascular endothelial growth factor (VEGF), aromatase P450 (P450arom), transforming growth factor-β (TGF-β) and matrix metalloproteinase (MMP)-2, were assessed using immunohistochemistry, an enzyme-linked immunosorbent assay and western blot analysis. Following CDDP treatment, the mean implant sizes were significantly reduced in Groups 2 and 3 compared with the control group (P=0.01). The mean histologic scores were also significantly lower in Groups 2 and 3. Furthermore, the protein expression of VEGF, P450arom, TGF-β and MMP-2 was significantly lower in Groups 2 and 3 when compared with the control group. A loss of hair was observed in 4 rats, which only occurred in Group 3. A dose-dependent effect was observed in the two CDDP-treated groups. In conclusion, the expression of proliferation- and angiogenesis-associated proteins was significantly lower following treatment with CDDP. CDDP caused a significant regression in the size of the endometriotic implants and induced atrophy of these lesions in rats.

Abstract
We report a case of vulvar clear cell adenocarcinoma in a woman presenting with a lump and pain in the right side of the labia majora. Three years prior to this visit, she underwent a total abdominal hysterectomy with bilateral salpingooophorectomy and excision of a labial mass. Pathological examination revealed adenomyosis and multiple leiomyomas in the uterus, endometriotic cysts in both ovaries, and foci of atypical endometriosis in the labial mass. The results of an incision biopsy performed before referral indicted only apocrine hidrocystoma. Physical examination revealed a hard mass at the right labia majora extending to the right groin. The mass seemed to be in continuity with the pubic symphysis that would require pubic bone excision and reconstruction with flap surgery to achieve complete resection. However, the patient refused such extensive surgery. Based on previous diagnosis of vulvar endometriosis, she had been treated with GnRH agonists and depot medroxyprogesterone acetate. However, the mass developed into an ulcer and increased in size. A second biopsy of the mass was undertaken, and the pathological diagnosis was clear cell carcinoma with coexisting atypical endometriosis. Computed tomography of the abdominopelvic region showed an ulcerative mass at the right labia majora and nodal metastasis at the external iliac and inguinal regions. Systemic chemotherapy was administered. The growth of the tumors stabilized during the first two cycles of chemotherapy but rapidly progressed thereafter. At 17 months after her initial presentation, the patient passed away due to the progression of the disease.

Abstract
Ovarian cancer is the most lethal of all common gynaecological malignancies in women worldwide. Ovarian cancer comprises of >15 distinct tumor types and subtypes characterized by histopathological features, environmental and genetic risk factors, precursor lesions and molecular events during oncogenesis. Recent studies on gene signature profiling of different subtypes of ovarian cancer have revealed significant genetic heterogeneity between and within each ovarian cancer histological subtype. Thus, an immense interest have shown towards a more personalized medicine for understanding the clinical and molecular complexities of four major types of epithelial ovarian cancer (serous, endometrioid, clear cell, and mucinous). As such, further in depth studies are needed for identification of molecular signalling network complexities associated with effective prognostication and targeted therapies to prevent or treat metastasis. Therefore, understanding the metastatic potential of primary ovarian cancer and therapeutic interventions against lethal ovarian cancer for the development of personalized therapies is very much indispensable. Consequently, in this review we have updated the key dysregulated genes of four major subtypes of epithelial carcinomas. We have also highlighted the recent advances and current challenges in unravelling the complexities of the origin of tumor as well as genetic heterogeneity of ovarian cancer.

Abstract
This retrospective analysis aimed to clarify the clinical and pathologic features of ovarian clear cell carcinoma (OCCC), and to determine the factors predictive of survival.Data waereextracted from OCCC patients who underwent primary surgery followed by adjuvant chemotherapy in Obstetrics & Gynecology Hospital of Fudan University between January2007 and December 2014. Kaplan-Meier survival estimates and Cox proportional hazards model were used for survival analyses.Of 130 patients (mean age = 56.2 years), 66.2% had stage I disease when the 5-year overall survival and 5-year disease-free survival were 89.2% and 88.1%, respectively. Patients frequently presented with large pelvic mass (>10 cm) and mild-to-moderate elevation of serological CA125 (≤200U/ mL). 60.7% of the cases at stage III/IV exhibited resistance to platinum-based chemotherapy; 37.69% of the tumors arose from endometriosis. On multivariate analysis, stage and chemoresistance were independent prognostic factors predictive for poorer survival. Survival at stage IC1 (surgical rupture) was comparable to that at stage IA (capsule intact), whereas survival at stage IC2/IC3 (rupture before surgery) was significantly worse than that at stage IA.OCCC shows distinct features compared to other epithelial ovarian cancers. FIGO stage and response to chemotherapy affect prognosis independently. Arising from endometriosis is not associated with better survival. Preoperative rupture rather than intraoperative rupture confers an adverse prognosis in otherwise stage IA disease.

Abstract
Ovarian clear cell carcinoma (oCCC) is a distinctive subtype of ovarian carcinoma, with peculiar genetic and environmental risk factors, precursor lesions, molecular events during oncogenesis, patterns of spread, and response to treatment. Because of low response to chemotherapy and poor prognosis in advanced stages, there is growing interest in investigating the molecular pathways involved in oCCC development, in order to individualize novel/molecular targeted therapies. Until now, the main molecular genetic changes associated with oCCC remain to be identified, and, although several molecular changes have been reported in clear cell tumors, most studies have analyzed a limited number of cases; therefore, the true prevalence of those changes is not known. The present review will present the clinicopathologic features of oCCC, from morphology to molecular biology, discussing the diagnostic and treatment challenges of this intriguing ovarian carcinoma.

Abstract
Ovarian clear cell adenofibroma is uncommon, and borderline clear cell adenofibroma (low malignant potential) is extremely rare. Borderline clear cell adenofibromas may represent the precursor lesion of clear cell adenocarcinoma of the ovary, but this has not been established. We present a case of a woman in her mid-50s with a clear cell adenofibroma ranging from benign to borderline to frankly invasive. While some clear cell adenocarcinomas are thought to arise from endometriosis, this range of findings supports the theory that some ovarian clear cell adenocarcinomas originate from borderline tumors.

Abstract
OBJECTIVES The present study assessed whether human telomerase reverse transcriptase (TERT) promoter mutations mediate the increased mortality risk observed in patients with ovarian clear cell carcinoma (CCC) and characterized the pathologic features of TERT promoter mutation-associated ovarian CCC. METHODS The TERT promoter region in genomic DNA extracted from paraffin-embedded ovarian CCC specimens (n = 93) was bidirectionally sequenced. RESULTS A total of 24 TERT promoter mutations were identified among the analyzed CCC cases, of which 11 were known "hotspot" mutations whose frequency was increased in CCC cases with compared to without coexistent adenofibroma (P < .05). In contrast, the 14 (including three novel) identified uncommon site mutations were shown to be associated with a poor progression-free survival rate (P < .01). CONCLUSIONS The identified uncommon TERT promoter mutations exacerbate the poor prognosis characteristic of ovarian CCC cases, and the hotspot mutations appear to be a molecular feature of the adenofibroma-associated form of the disease.

Abstract
Borderline clear cell tumors are extremely rare, and few cases have been reported in the literature. Herein, we present a case of borderline clear cell adenofibroma of the ovary in a 58-year-old woman who presented with a pelvic mass and constipation. Physical examination revealed a 10 cm solid midline pelvic mass. Computed tomography showed an 8 cm heterogeneous enhancing mass attached to the left posterolateral wall of the uterus. The patient's serum CA 125 levels were slightly elevated (80.9 U/ml). The patient was given a total abdominal hysterectomy with bilateral salpingooophorectomy. On gross examination, it was found that the left ovarian tumor was an 8.0 × 7.5 × 8.0 cm solid multilobulated mass containing tiny cysts. Histologically, the tumor was composed of small glands in dense fibrous and myxoid stroma. The glands were lined with cuboidal cells with clear cytoplasm and mild to moderate nuclear atypia. No stromal invasion was observed. The pathological diagnosis was borderline clear cell adenofibroma of the left ovary. There was no reoccurrence 36 months post operation.

Abstract
PURPOSE To retrospectively compare the MR findings of histological subtypes of clear cell carcinomas (CCCs) of the ovary. MATERIALS AND METHODS This single-center retrospective study was approved by the institutional review board, and the requirement for informed consent was waived. Between April 2005 and August 2015, we found 51 consecutive patients with histopathologically proven CCCs. Among them, 44 CCCs in 37 patients who underwent preoperative MR imaging were included. CCCs were pathologically divided into three subgroups: (1) four clear cell adenofibroma-associated CCCs, (2) 21 endometriosis-associated CCCs, and (3) 19 indeterminate CCCs. The statistical tests were used to compare the frequency of qualitative assessments and value of quantitative measurements among the histological subtypes. RESULTS On T2-weighted images, hypointense areas within solid components were more frequently observed in clear cell adenofibroma-associated CCCs [3/4 (75%)] than in the remaining CCCs [1/40 (3%)] (p < 0.01), and the signal intensity ratios (SIRs) of solid components were significantly lower in clear cell adenofibroma-associated CCCs (0.27 ± 0.13) than in the remaining CCCs (0.61 ± 0.18) (p < 0.01). On T1-weighted images, hyperintensities of cystic components were more frequently observed in the endometriosis-associated CCCs [17/21 (81%)] than in the remaining CCCs [5/20 (25%)] (p < 0.01), and the SIRs of cystic components were significantly higher in endometriosis-associated CCCs (2.99 ± 1.51) than in the remaining CCCs (1.82 ± 1.10) (p < 0.01). CONCLUSION MR features may help differentiate between adenofibroma-associated and endometriosis-associated CCC.

Abstract
This study was to investigate the effects of cisplatin (CDDP) and letrozole on surgically induced endometriosis and comparison of the two drugs in a rat model. Endometriosis was surgically induced by autologous transplantation of endometrial pieces. Thirty model rats were divided into three groups, randomly. Group 1 (n=10) served as control and received no medication. Group 2 (n=10) received 0.2mg/kg/day of oral letrozole. Group 3 (n=10) received 35mg/m(2) CDDP via peritoneal perfusion every four days. All the rats were treated for 24days. The growth and histologic score of the implants were evaluated. The proliferation- and angiogenesis-associated proteins were assessed using immunohistochemistry and western blotting. The serum sex hormones were assayed using ELISA. After the medication, the growth and histologic score of the implants were significantly lower in the 2 and 3 groups than in the control group. The protein expressions of vascular endothelial growth factor (VEGF), aromatase P450 (P450arom), transforming growth factor-beta (TGF-β), and matrix metalloproteinase (MMP)-2, were significantly lower in groups 2 and 3 than in the control group. Further, the P450arom level was lower in the letrozole group than in the CDDP group. The TGF-β and MMP-2 levels were lower in the CDDP group than in the letrozole group. Serum T level was significantly higher in the letrozole group, and serum E2 level was lower in the letrozole group. In conclusion, cisplatin and letrozole caused similar regression of the implants in the endometriosis model rats. But their effects on the proliferation- and angiogenesis-associated protein expressions and the serum sex hormone levels were different. Cisplatin and letrozole might cause the effects in the endometriotic foci through different mechanism.

Abstract
Ovarian clear cell adenocarcinomas (CCACs) are frequently associated with endometriosis and, less often with clear cell adenofibromas (CCAFs). We encountered a case of ovarian CCAC arising from benign and borderline adenofibromas of the clear cell and endometrioid types with endometriosis in a 53-year-old woman. Regions of the adenofibromas showed transformation to CCAC and regions of the endometriosis showed atypical endometriotic cysts. This case demonstrates that CCAC can arise from CCAF or endometriosis.

Abstract
UNLABELLED Recent molecular and pathological studies suggest that endometriosis may serve as a precursor of ovarian cancer (endometriosis-associated ovarian cancer, EAOC), especially of the endometrioid and clear cell subtypes. Accordingly, this study had two cardinal aims: first, to obtain mutation profiles of EAOC from Taiwanese patients; and second, to determine whether somatic mutations present in EAOC can be detected in preneoplastic lesions. Formalin-fixed paraffin-embedded (FFPE) tissues were obtained from ten endometriosis patients with malignant transformation. Macrodissection was performed to separate four different types of cells from FFPE sections in six patients. The four types of samples included normal endometrium, ectopic endometriotic lesion, atypical endometriosis, and carcinoma. Ultra-deep (>1000×) targeted sequencing was performed on 409 cancer-related genes to identify pathogenic mutations associated with EAOC. The most frequently mutated genes were PIK3CA (6/10) and ARID1A (5/10). Other recurrently mutated genes included ETS1, MLH1, PRKDC (3/10 each), and AMER1, ARID2, BCL11A, CREBBP, ERBB2, EXT1, FANCD2, MSH6, NF1, NOTCH1, NUMA1, PDE4DIP, PPP2R1A, RNF213, and SYNE1 (2/10 each). Importantly, in five of the six patients, identical somatic mutations were detected in atypical endometriosis and tumor lesions. In two patients, genetic alterations were also detected in ectopic endometriotic lesions, indicating the presence of genetic alterations in preneoplastic lesion. Genetic analysis in preneoplastic lesions may help to identify high-risk patients at early stage of malignant transformation and also shed new light on fundamental aspects of the molecular pathogenesis of EAOC. KEY MESSAGES Molecular characterization of endometriosis-associated ovarian cancer genes by targeted NGS. Candidate genes predictive of malignant transformation were identified. Chromatin remodeling, PI3K-AKT-mTOR, Notch signaling, and Wnt/β-catenin pathway may promote cell malignant transformation.

Abstract
Clear cell carcinoma of ovary is uncommon ovarian tumour that arises from surface epithelium of ovary. It has well-known association with ovarian endometriosis. We report here the first case of bilateral clear cell carcinoma of ovaries in a 40-year-old woman with a 17-year history of bilateral ovarian endometriosis. In addition, during the longstanding duration of the endometriosis, the patient was treated with hormonal therapy, including oestrogen. It represents the first report of such bilateral involvement in the background of ovarian endometriosis. This should prompt clinicians to be aware that prolonged hormonal treatment of endometriosis may precipitate bilateral malignancy of the ovary.

Int J Gynecol Cancer 2015; 25:1239-47. [PMID: 26035126 PMCID: PMC4549863 DOI: 10.1097/igc.0000000000000484] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Revised: 03/18/2015] [Accepted: 04/01/2015] [Indexed: 01/22/2023] Open
Abstract
OBJECTIVE The objective of this study was to compare immunohistochemical profile for the apoptosis regulators p53, C-MYC, bax, PUMA, and PTEN and the cell cycle regulatory proteins p21 and p27, as well as clinical factors between types I and II tumors. METHODS In total, 131 patients in FIGO (International Federation of Gynecology and Obstetrics) stages I-II were divided into 2 groups of patients after type I tumors (n = 79) and type II tumors (n = 52). Differences in the immunohistochemical profile for the cell cycle-related proteins, detected by tissue microarrays and immune-histochemistry, were compared. For statistical tests, the Pearson χ test and the logistic regression model were used. All tests were 2-sided, and the level of statistical significance was P ≤ 0.05. RESULTS In multivariate logistic regression analysis with recurrent disease as endpoint, FIGO stage (odds ratio [OR], 4.7), type I/II tumors (OR, 3.8), body mass index (BMI) (OR, 3.5), and p53 status (OR, 4.2) all were found to be independent predictive factors. In 2 different multivariate logistic regression analyses with type I/II tumors as endpoint, both p53p21 (OR, 2.9) and p27 status (OR, 3.0) were associated with type II tumors. Differently, C-MYC status (OR, 0.4) was associated with type I tumors. Furthermore, age (OR, 1.04), BMI (OR, 0.4), and recurrent disease (OR, 4.3) all were associated to type II tumors. In survival analysis, there was a trend (P = 0.054) toward better disease-free survival for patients with type I tumors. CONCLUSIONS Concomitant positivity for p53 and negativity for p21, positivity for p27, and negativity for C-MYC in an epithelial ovarian tumor might strengthen the diagnostic option of type II tumor ovarian carcinoma. Patients with type II tumors were older, had lower BMI, and had more often recurrent disease than patients with type I tumors.

Abstract
AIMS The carcinogenesis of ovarian clear cell carcinoma (CCC) has been hypothesized to comprise two different pathways: an adenofibroma-carcinoma sequence and an endometriosis-carcinoma sequence. However, the difference in the genetic basis of these two pathways remains unclear. Recent studies have suggested that an ARID1A mutation and the loss of the corresponding protein, BAF250a, are frequent events in CCC. Herein, we investigated the difference in the loss of BAF250a expression in adenofibroma-related CCC and endometriosis-related CCC. METHODS AND RESULTS In total, 93 cases of surgically treated CCC were evaluated. The presence of adenofibroma and endometriosis associated with carcinoma was determined by reviewing haematoxylin and eosin-stained slides for each case. BAF250a expression in carcinoma was examined immunohistochemically. The loss of BAF250a expression was detected in carcinomas in 50 of 93 (54%) cases, including five of 18 (28%) with adenofibroma alone, 30 of 45 (67%) with endometriosis alone, eight of 18 (44%) with both conditions and seven of 12 (58%) with neither condition. The loss of BAF250a expression was significantly less frequent in CCC cases with adenofibroma than in cases with endometriosis (P = 0.01, Fisher's exact test). CONCLUSIONS The action of ARID1A in carcinogenesis differs between adenofibroma-related CCC and endometriosis-related CCC.

Abstract
BACKGROUND Clear cell carcinomas are aggressive tumors with a distinct biologic behaviour. In a genome-wide screening for genes involved in chemo-resistance, NAPA was over-expressed in cisplatin-resistant cells. The NAPA (protein) Napsin A was described to promote resistance to cisplatin by degradation of the tumor suppressor p53. METHODS Totally 131 patients were included in this study all in FIGO-stages I-II; 16 were clear cell tumors which were compared with 40 Type I tumors and 75 type II tumors according to the markers Napsin A, p21, p53 and p27 and some clinical features. For detection of the markers tissue microarrays and immunohistochemistry were used. RESULTS Positivity for Napsin A was detected in 12 (80%) out of the 15 clear cell tumors available for analysis compared with 3 (4%) out of the Type I and II tumors in one group (p<0.001). Differences in p21 status, p53 status, and p21+p53- status were striking when clear cell tumors were compared with Type I, Type II, and Type I and II tumors in one group, respectively. The p21+p53-status was associated to positive staining of Napsin A (p=0.0015) and clear cell morphology (p=0.0003). In two separate multivariate logistic regression analyses with Napsin A as endpoint both clear cell carcinoma with OR=153 (95% C.I. 21-1107); (p<001) and p21+p53- status with OR=5.36 (95% C.I. 1.6-17.5); (p=0.005) were independent predictive factors. ROC curves showed that AUC for Napsin A alone was 0.882, for p21+p53- it was 0.720 and for p21+p53-Napsin A+AUC was 0.795. Patients with clear cell tumors had lower (p=0.013) BMI than Type I patients and were younger (p=0.046) at diagnosis than Type II patients. Clear cell tumors had a higher frequency (p=0.039) of capsule rupture at surgery than Type I and II tumors. CONCLUSIONS Positivity of Napsin A in an epithelial ovarian tumor might strengthen the morphological diagnosis of clear cell ovarian carcinoma in the process of differential diagnosis between clear cell ovarian tumors and other histological subtypes.

Abstract
Ovary benign clear cell adenofibroma (CCAF) is extremely rare. Here, we reported a 38-year-old woman with CCAF who was given sequential cyclic hormone replacement therapy for eight years due to premature ovarian failure (POF). At operation, we found adenofibromas in both ovaries and well encapsulated. The cut surface was cystic and solid in appearance, and multilocular cysts embedded in hard stroma. Determination of sex hormone levels in the fluid of cysts of the ovary showed normal level. Clear cell cystadenofibroma proliferation was found in ovarian stroma while atrophy in ovarian cortex. Histological examination revealed that the glands were lined by 1 or 2 layers of hobnail cells with scant to moderate pale or clear cytoplasm. The nuclei were small uniform, and flat to round. Neither primary follicles nor secondary follicles were observed in ovary cortex. Immunohistochemical results showed that EMA and p53 were positive while Calretinin was negative. In this article, we reviewed literatures and analyzed both clinical and pathological features of ovary benign clear cell adenofibromas.

Abstract
BACKGROUND The clear cell borderline ovarian tumor (CCBOT) of the ovary is a rare tumor accounting for less than 1% of BOT. Fewer than 25 cases have been reported in the literature (including details on clinical management and outcomes). The aim of this study was to determine the prognosis of a series of CCBOTs collected in 2 reference centers. PATIENTS AND METHODS This was a retrospective review of patients with CCBOT treated or referred to our institutions. A centralized histological review by a reference pathologist and data on the clinical characteristics, management, and outcomes of patients were required for inclusion. RESULTS Twelve patients were identified between 2000 and 2010. The median age of patients was 68 years (range, 36-83 years). Two had been treated conservatively and 9 radically (data unknown in 1). The tumor was unilateral in 11 cases. All patients had stage I disease. All cases were CCBOT with an adenofibromatous pattern. Stromal microinvasion or intraepithelial carcinoma was histologically associated in 2 and 3 cases, respectively. Four of the 12 patients had synchronous endometrial disorders (but no endometrioid carcinoma). No cases were histologically associated with endometriosis. Four patients were lost to follow-up. Among 8 other patients, after a median period of 28 months (range, 2-129 months), no recurrence had occurred (1 patient had died of another disease). CONCLUSION Clear cell borderline ovarian tumor carries a good prognosis. All tumors are stage I; therefore, surgical staging is not necessary in most of the cases. Conservative treatment could be proposed to young patients, but uterine curettage would then be required in cases of uterine preservation.

Abstract
UNLABELLED Clear cell carcinomas (CCC) of the mullerian system are considered high grade tumors, but morphologically, the cells of CCC show both low and high grade features. The aims of the current study were to categorize CCC into low and high nuclear grade types, correlate their association with endometriosis, and then observe possible variations in pathogenesis based on their expression of p53 and Ki-67. We studied 41 pure mullerian CCCs and designated each as either a high (HNG) or low (LNG) nuclear grade tumor. Morphologically, 17 (41%) CCCs were LNG and 24 (59%) were HNG. Nine (38%) HNG and 2 (12%) LNG tumors showed positive immunostaining with p53. Endometriosis was associated with 8 (47%) LNG tumors and 8 (33%) HNG CCCs. Of the 11 cases with p53 alteration, 4 (1 LNG and 3 HNG) were associated with endometriosis. CONCLUSIONS HNG CCCs, irrespective of their association with endometriosis, have alterations of p53. In general, LNG ovarian and endometrial CCCs, irrespective of their association with endometriosis/adenomyosis, are less likely to show p53 alteration. It appears that mullerian CCCs may have variable pathogenesis depending on their nuclear grade and association with endometriosis. A larger study is needed to validate these findings.

Abstract
Ovarian cancer represents one of the cancers with the worst prognostic in adult women. More than half of the patients who present with clinical signs such as abdominal bloating and a feeling of fullness already show advanced stages. The majority of ovarian cancers grow as cystic masses, and cancer cells easily spread into the pelvic cavity once the cysts rupture or leak. When the ovarian cancer cells disseminate into the peritoneal cavity, metastatic nests may grow in the cul-de-sac, and in more advanced stages, the peritoneal surfaces of the upper abdomen become the next largest soil for cancer progression. Ascites is also produced frequently in ovarian cancers, which facilitates distant metastasis. Clinicopathologic, epidemiologic and molecular studies on ovarian cancers have improved our understanding and therapeutic approaches, but still further efforts are required to reduce the risks in the patients who are predisposed to this lethal disease and the mortality of the patients in advanced stages. Among various molecules involved in ovarian carcinogenesis, special genes such as TP53, BRCA1 and BRCA2 have been well investigated. These genes are widely accepted as the predisposing factors that trigger malignant transformation of the epithelial cells of the ovary. In addition, adnexal inflammatory conditions such as chronic salpingitis and ovarian endometriosis have been great research interests in the context of carcinogenic background of ovarian cancers. In this review, I discuss the roles of stromal cells and inflammatory factors in the carcinogenesis and progression of ovarian cancers.

Abstract
Inflammation plays a role in the pathogenesis of endometriosis. Endometriosis-associated ovarian carcinogenesis might be promoted through oxidative stress-induced increased genomic instability, aberrant methylation, and aberrant chromatin remodeling, as well as mutations of tumor suppressor genes. Aberrant expression of ARID1A, PIK3CA, and NF-kB genes has been recognized as the major target genes involved in oxidative stress-induced carcinogenesis. HNF-1beta appears to play a key role in anti-oxidative defense mechanisms. We discuss the pathophysiologic roles of oxidative stress as somatic mutations as well as highly specific agents that effectively modulate these targets.

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.
