Abstract
BACKGROUND Teratomas are a common type of germ cell tumor. However, only a few reports on their genomic constitution have been published. The study of teratomas may provide a better understanding of their stepwise differentiation processes and molecular bases, which could prove useful for the development of tissue-engineering technologies. METHODS In the present study, we analyzed the copy number aberrations of nine ovarian mature cystic teratomas using array comparative genomic hybridization in an attempt to reveal their genomic aberrations. RESULTS The many chromosomal aberrations observed on array comparative genomic hybridization analysis reveal the complex genetics of this tumor. Amplifications and deletions of large DNA fragments were observed in some samples, while amplifications of EVX2 and HOXD9-HOXD13 on 2q31.1, NDUFV1 on 11q13.2, and RPL10, SNORA70, DNASE1L1, TAZ, ATP6AP1, and GDI1 on Xq28 were found in all nine mature cystic teratomas. CONCLUSIONS Our results indicated that amplifications of these genes may play an important etiological role in teratoma formation. Moreover, amplifications of EVX2 and HOXD9-HOXD13 on 2q31.1, found on array comparative genomic hybridization, may help to explain the characteristics of teratomas in chondrogenesis and osteogenesis.

Abstract
Background Mature cystic teratomas of the ovary are the most common type of germ cell tumor, comprising 33% of ovarian tumors. Studying these tumors may result in a better understanding of their stepwise developmental processes and molecular bases and provide useful information for the development of tissue-engineering technologies. Methods In the present study, 9 mature cystic teratomas of the ovary were analyzed by whole-exome sequencing and the results were compared with the Catalogue of Somatic Mutations in Cancer and dbSNP databases. Results Mutations were validated in 15 genes with alterations in all 9 (100%) samples and changes in protein coding. The top 10 mutated genes were FLG, MUC17, MUC5B, RP1L1, NBPF1, GOLGA6L2, SLC29A3, SGK223, PTGFRN, and FAM186A. Moreover, 7 variants in exons with changes in protein coding are likely of importance in the development of mature cystic teratomas of the ovary, namely PTGFRN, DUSP5, MPP2, PHLDA1, PRR21, GOLGA6L2, and KRTAP4-2. Conclusions These genetic alterations may play an important etiological role in teratoma formation. Moreover, novel mutations in DUSP5 and PHLDA1 genes found on whole-exome sequencing may help to explain the characteristics of teratomas.

Abstract
ZusammenfassungReife Teratome sind die häufigsten benignen Raumforderungen des Ovars. Bei Kindern werden diese häufig durch eine Ovarialtorsion symptomatisch, welche den Verlust des Organs zur Folge haben kann. In seltenen Fällen manifestieren sich diese benignen Tumoren metachron auch nach mehreren Jahren auf der Gegenseite.Berichtet wird von einem bei Erstdiagnose 6‑jährigen Mädchen, bei welchem zweimal im Abstand von 5 Jahren ein jeweils histologisch gesichertes, reifes Teratom des Ovars nachgewiesen wurde. Beide Male wurde der Tumor der betroffenen Seite durch eine Ovarialtorsion symptomatisch. Beim Erstereignis erfolgte eine linksseitige Tumor- und Ovarexstirpation. Der nach 5 Jahren zeitverzögert aufgetretene Tumor der Gegenseite entwickelte sich in einem Zeitraum von nur ca. 8 Monaten zur zuvor eindeutig unauffälligen Sonographie. Durch die rechtzeitige Diagnosestellung beim Zweitereignis konnte das verbliebene rechte Ovar letztendlich erhalten werden.Dieser ungewöhnliche Fallbericht soll die Bedeutung regelmäßiger Follow-up-Untersuchungen insbesondere bei Kindern mit Ovarektomie aufgrund eines reifen Teratoms hervorheben und die Aufmerksamkeit für diese bei Kindern zwar seltene, aber potenziell komplikationsbehaftete Differenzialdiagnose schärfen.

Abstract
Wilms' tumour is a solid tumour that frequently occurs in children. Genetic changes in WT1 and epigenetic aberrations that affect imprinted control region 1 in WT2 loci are implicated in its aetiology. Moreover, tumour suppressor genes are frequently silenced by methylation in this tumour. In the present study, we analysed the methylation statuses of promoter regions of 24 tumour suppressor genes using a methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA)-based approach in 6 Wilms' tumours. Methylation of RASSF1 was specific to all 6 Wilms' tumours and was not observed in normal tissues. Moreover, methylated HIC1 was identified in stromal-type Wilms' tumours and methylated BRCA1 was identified in epithelial-type Wilms' tumours. Unmethylated CASP8, RARB, MLH1_167, APC and CDKN2A were found only in blastemal predominant-type Wilms' tumour. Our results indicated that methylation of RASSF1 may be a vital event in the tumorigenesis of Wilms' tumour, which informs its clinical and therapeutic management. In addition, mixed-type Wilms' tumours may be classified according to epithelial, stromal and blastemal components via MS-MLPA-based approach.

Abstract
BACKGROUND Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10%-20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian-sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed. DESIGN This study reviews the clinical data of patients with OMT, and analyzes risk factors for second events. A national retrospective review of girls under 18 years of age with OMTs was performed. Data on clinical features, imaging, laboratory studies, surgical reports, second events and their management were retrieved. RESULTS Overall, 350 children were included. Eighteen patients (5%) presented with a synchronous bilateral form at diagnosis. Surgery was performed by laparotomy (85%) and laparoscopy (15%). OSS and TO were performed in 59% and 41% of cases, respectively. Perioperative tumor rupture occurred in 23 cases, independently of the surgical approach. Twenty-nine second events occurred (8.3%) in a median time of 30.5 months from diagnosis (ipsilateral: eight cases including one malignant tumor; contralateral: 18 cases; both ovaries: three cases). A large palpable mass, bilateral forms, at diagnosis and perioperative rupture had a statistical impact on the risk of second event, whereas the type of surgery or approach did not. CONCLUSION This study is a plea in favor of OSS as the first-choice treatment of OMT when possible. Close follow-up during the first 5 years is mandatory considering the risk of 8.3% of second events, especially in cases with risk factors.

Abstract
There is increasing recognition that contralateral metachronous tumor may occur following treatment of unilateral mature ovarian teratoma. We aimed to define this risk to guide appropriate surveillance strategies. We undertook a systematic review of three large medical databases (Ovid Medline, Embase, and Cochrane Controlled Trials Register) to April 2020 using a defined search strategy. From 1831 articles retrieved, 23 were included, reporting 1101 girls with unilateral mature ovarian teratomas. The intensity and duration of follow-up varied between studies, with only five reporting close surveillance. Overall prevalence of metachronous contralateral mature teratoma was 2.1%, with a prevalence per study of 0%-23% (median 0%). Prevalence was higher (7%) among studies with more robust surveillance. These data suggest a small but real risk of metachronous contralateral tumors. Surveillance ultrasonography is proportionate and indicated alongside further prospective data collection to record the natural history and impact of surveillance in greater detail.

Abstract
BACKGROUND There are limited studies on Sertoli-Leydig cell tumors (SLCTs) and no data in the population of Chinese patients with SLCTs from the genetic level. In addition, previous studies on SLCTs have focused exclusively on mutations in the DICER1 gene and no data exists on the genetic landscape of SLCTs. METHODS Patients with moderately or poorly differentiated SLCTs who underwent surgical resection between January 2012 and October 2018 in our institution were recruited. Whole exome sequencing was performed on formalin-fixed, paraffin-embedded tumor tissue and peripheral blood or normal tissue samples. RESULTS Seventeen patients were recruited with 19 tumor samples. The rate of tumor-associated germline mutations was 6 of 17 (35.3%), and that of DICER1 germline mutations was 4 of 17 (23.5%). Regarding clinical relapse, patients with germline tumor-associated mutations had significantly poorer prognosis than those without (p = .007), and those with germline DICER1 mutations were relatively more likely to exhibit clinical relapse, although not to a significant degree (p = .069). Regarding somatic mutations, firstly, the subclone evolution analysis demonstrated that the two tumors on the contralateral ovary were primary tumors, respectively. Secondly, somatic mutations were most commonly found in CDC27 (10/19, 52.6%), DICER1 (4/19, 21.1%), and MUC22 (4/19, 21.1%). And the analysis of cancer cell fractions showed that DICER1 mutations were correlated with tumorigenesis of SLCTs. The rates of germline and somatic DICER1 mutations were higher in patients who were younger than 18 years than those in older patients (p = .022 and p = .001, respectively). CONCLUSION Our study indicates that genetic testing may have important clinical significance for patients with SLCTs, particularly for younger patients. IMPLICATIONS FOR PRACTICE Bilateral ovarian Sertoli-Leydig cell tumors were verified to be primary tumors from the genetic perspective. The rates of germline and somatic DICER1 mutations were 4 of 17 (23.5%) and 4 of 19 (21.1%), respectively. The rates of germline and somatic DICER1 mutations were higher in patients who were younger than 18 years than those in older patients (p = .022 and p = .001, respectively).

Imprinting aberrations of SNRPN, ZAC1 and INPP5F genes involved in the pathogenesis of congenital heart disease with extracardiac malformations. J Cell Mol Med 2020; 24:9898-9907. [PMID: 32693431 PMCID: PMC7520315 DOI: 10.1111/jcmm.15584] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 05/28/2020] [Accepted: 06/05/2020] [Indexed: 12/12/2022] Open
Abstract
Congenital heart disease (CHD) with extracardiac malformations (EM) is the most common multiple malformation, resulting from the interaction between genetic abnormalities and environmental factors. Most studies have attributed the causes of CHD with EM to chromosomal abnormalities. However, multi‐system dysplasia is usually caused by both genetic mutations and epigenetic dysregulation. The epigenetic mechanisms underlying the pathogenesis of CHD with EM remain unclear. In this study, we investigated the mechanisms of imprinting alterations, including those of the Small nuclear ribonucleoprotein polypeptide N (SNRPN), PLAG1 like zinc finger 1 (ZAC1) and inositol polyphosphate‐5‐phosphatase F (INPP5F) genes, in the pathogenesis of CHD with EM. The methylation levels of SNRPN, ZAC1, and INPP5F genes were analysed by the MassARRAY platform in 24 children with CHD with EM and 20 healthy controls. The expression levels of these genes were detected by real‐time polymerase chain reaction (PCR). The correlation between methylation regulation and gene expression was confirmed using 5‐azacytidine (5‐Aza) treated cells. The methylation levels of SNRPN and ZAC1 genes were significantly increased in CHD with EM, while that of INPP5F was decreased. The methylation alterations of these genes were negatively correlated with expression. Risk analysis showed that abnormal hypermethylation of SNRPN and ZAC1 resulted in 5.545 and 7.438 times higher risks of CHD with EM, respectively, and the abnormal hypomethylation of INPP5F was 8.38 times higher than that of the control group. We concluded that abnormally high methylation levels of SNRPN and ZAC1 and decreased levels of INPP5F imply an increased risk of CHD with EM by altering their gene functions. This study provides evidence of imprinted regulation in the pathogenesis of multiple malformations.

BMC Cancer 2018; 18:1147. [PMID: 30463533 PMCID: PMC6249857 DOI: 10.1186/s12885-018-4932-2] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Accepted: 10/10/2018] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Fertility sparing surgery has been extensively performed among patients with borderline ovarian tumors due to their age and favorable prognosis. Nevertheless, the prognosis and obstetric outcomes in these patients remain uncertain. Thus, the current study was carried out to evaluate the oncological safety and fertility benefits of different fertility sparing surgery subtypes and various clinicopathological parameters. METHODS Young borderline ovarian tumor patients with an age of ≤40 years, who were admitted and treated in Zhejiang Cancer Hospital from January 1996 to December 2016, were enrolled in this study and reviewed retrospectively. The prognostic and obstetric effects of clinicopathological and surgical variables were evaluated using univariate/multivariate analyses and survival curves. RESULTS A total of 92 eligible patients were enrolled in the analysis. Among these patients, 22 (24%) patients showed recurrence after a median follow-up of 46.5 months. Within the fertility sparing surgery group, patients at advanced stage (≥stage II), of serous type, with micropapillary and bilateral tumors were associated with a higher recurrence rate and a shorter recurrence interval. In terms of different modalities of fertility sparing surgery, adnexectomy was remarkably favored over cystectomy-including (P = 0.012); unilateral salpingo-oophorectomy had better prognosis than cystectomy and bilateral cystectomy was favored over unilateral salpingo-oophorectomy+contralateral cystectomy. Univariate Cox regression analysis indicated that the International Federation of Gynecology and Obstetrics stage (≥Stage II), the presence of bilateral and micropapillary lesions, and the application of cystectomy-including surgery were correlated with poorer disease-free survival, while the mucinous type of borderline ovarian tumors was related to improved disease-free survival. In this study, a total of 22 patients attempted to conceive and 15 (68%) of these patients achieved successful pregnancy. CONCLUSIONS Unilateral salpingo-oophorectomy and bilateral cystectomy should be recommended as the preferred choice of treatment for young patients with unilateral and bilateral borderline ovarian tumor who desire to preserve fertility. In addition, borderline ovarian tumor patients at advanced stage (≥stage II), of serous type, with micropapillary and bilateral tumors should pay more attention to the risk of recurrence. Therefore, these patients should choose fertility sparing surgery carefully and attempt to achieve pregnancy as soon as possible.

Abstract
BACKGROUND Cryopreservation of oocytes is an efficient method of fertility preservation (FP) that can be applied in women suffering from gynecologic conditions that menace their reproductive future. Collection of oocytes becomes challenging in some scenarios, like the possibility of an ovarian cancer, the "ex-vivo" harvest of oocytes for FP, aspirating follicles directly from the ovarian specimen already excised by laparotomy or laparoscopy and it is an option for these cases. CASE PRESENTATION In the present case report, the case of a patient with an adnexal mass suspected to be a recurrent teratoma was described who referred to our Assisted Reproduction Unit in Hospital Quironsalud Malaga for FP counseling. After controlled ovarian hyperstimulation, followed by laparoscopic abdominal examination and oophorectomy, an ex-vivo follicular aspiration for oocyte retrieval was performed on the specimen, using a standard ultrasound-guided procedure to ease and improve the process. All the follicles were aspirated and 5 metaphase II oocytes were obtained. CONCLUSION This is to our knowledge, the first communication describing the ex-vivo ovarian aspiration of mature oocytes for FP using standard ultrasound guidance. Although this ultrasound guidance is not completely necessary, as other authors demonstrated previously, such a procedure permitted an easy and complete harvest of oocytes in a rare tumor with bizarre cystic formations, which made follicle recognition very difficult.
