Ovarian germ cell tumors (OGCTs) and sex cord stromal tumors (SCSTs) are rare gynecologic tumors that are derived from germ and stromal cells, respectively. Unlike their epithelial counterparts, molecular pathogenesis of these tumor types is still poorly understood. Here, we characterized microRNA (miRNA) expression profiles of 9 OGCTs (2 malignant and 7 benign) and 3 SCSTs using small RNA sequencing. We observed significant miRNA expression variations among the three tumor groups. To further demonstrate the biological relevance of our findings, we selected 12 miRNAs for validation in an extended cohort of 16 OGCTs (9 benign and 7 malignant) and 7 SCSTs by reverse transcription-quantitative polymerase chain reaction...

The incidence of ovarian cancer depends on the ethnicity and geographical area. Menopausal status is a well-known risk factor for ovarian cancer and most cases occur after menopause in Caucasians. However, it is less clear how the status of menopause or age at diagnosis is associated with ovarian cancer including its subtypes in Chinese women. Data on 1,283 women with primary malignant or borderline ovarian cancer including age at diagnosis, age at menopause and histology from the largest women's hospital in China was analysed...

BACKGROUND: Malignant ovarian germ cell tumors are rare, and often treatable with surgery and chemotherapy. Few data are available for treatment of platinum-resistant tumors. CASE: A 31 year old gravida 0 with a 20 cm pelvic mass was found to have a malignant ovarian germ cell tumor after she underwent debulking surgery. She initially responded to chemotherapy; however her AFP began to rise before all cycles were completed. She underwent additional debulking surgery that was again suboptimal...

BACKGROUND: Malignant ovarian germ cell tumors (MOGCTs) are a rare form of ovarian malignancy. Socioeconomic status (SES) has been shown to affect survival in several gynecologic cancers. We examined whether SES impacted survival in adolescent and young adults (AYAs) with MOGCT. MATERIALS AND METHODS: The National Cancer Data Base was used to identify AYAs (aged 15-39 years) with MOGCT from 1998 to 2012. Three SES surrogate variables identified were as follows: insurance type, income quartile, and education quartile...

Germ cell tumors which arise mainly in pediatric and adolescent age group, account for 30% of all ovarian tumors, but constitute only 5% of all malignant ovarian tumors. The presentation is usually insidious with the patient presenting with abdominal swelling and dull aching pain. We report a rare case of a malignant germ cell tumor in a 12-year-old girl who presented with acute abdomen due to spontaneous rupture of tumor resulting in hemoperitoneum. The patient was taken up for emergency laparotomy and left salpingo-opherectomy with omentectomy and drainage of hemoperitoneum was done...

OBJECTIVE: To date, epidemiological evidence has consistently supported a link between ovarian cancer risk and menopause. However, little is known about how menopause status affects the risk of specific histological subtypes of ovarian tumors. We aimed to analyze the differences in various histopathological subtypes of ovarian tumors between pre- and postmenopausal women. METHODS: We reviewed the medical records of women who underwent surgery for ovarian tumors and received histopathological confirmation at the Busan Paik Hospital between January 1997 and October 2016...

Dermoid cysts account for 10-20% of ovarian germ cell tumors. Malignant transformation within ovarian dermoid cyst has been reported in 1-2 per cent of the cases. The treatment remains controversial. In women of childbearing age and in the first stages of the disease unilateral annexectomy without adjuvant therapy is recommended. In menopausal women extensive surgery is sometimes performed, no matter what stage of the disease the person is experiencing. We report the case of a menopausal patient with malignant transformation within ovarian dermoid cyst who underwent surgery...

Human chorionic gonadotropin β (β-hCG) is a well-known and accurate marker for the diagnosis and monitoring of pregnancy, trophoblastic tumors and ovarian germ cell tumors. Recently, β-hCG has been found to be closely related to poor prognosis and metastasis in various other malignant tumors, while its role and mechanism in ovarian cancer is still unclear. In the present study, lentiviral‑mediated transfection and small interfering RNA (siRNA) were used to alter β-hCG expression in the ovarian cancer cell lines ES-2 and SKOV3, respectively...

Ovarian immature teratoma is a germ cell tumor that comprises less than 1% of ovarian cancers and is treated with surgical debulking and chemotherapy depending on stage. Growing teratoma syndrome (GTS) is the phenomenon of the growth of mature teratoma elements with normal tumor markers during or following chemotherapy for treatment of a malignant germ cell tumor. These tumors are associated with significant morbidity and mortality due to invasive and compressive growth as well as potential for malignant transformation...

Mature cystic teratoma is the most common kind of ovarian germ cell tumor. Malignant transformation is uncommon, with thyroid cancer rarely found. Papillary thyroid microcarcinoma has rarely been described as associated with ovarian teratomas. We report a case of a 34-year-old woman who presented with abdominal pain and an ovarian mass. After surgery, the patient was diagnosed with a follicular variant papillary thyroid microcarcinoma that arose within a mature cystic ovarian teratoma. Based on the small size of the primary lesion and patient preferences, no further treatment was performed...

The purpose of this study was to determine the expression and potential clinical role of epithelial-to-mesenchymal transition (EMT)-related factors in malignant ovarian germ cell tumors (MOGCT). Protein expression of E-cadherin, N-cadherin, P-cadherin, Zeb1, HMGA2, and vimentin by immunohistochemistry was analyzed in 42 MOGCT from patients treated in Norway during the period 1981-2001. Expression was analyzed for association with clinicopathologic parameters. E-cadherin (p = 0.016) and HMGA2 (p = 0.002) expression was significantly higher in immature teratomas and yolk sac tumors compared with dysgerminomas...
