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...

Ovarian germ cell tumors (GCTs) are rare and affect mainly young girls and women. Two histological groups are distinguished: dysgerminomas and nondysgerminomatous tumors. These tumors have initial good responses to surgery and chemotherapy in 80% cases, but >75% of patients die due to complications of disease progression. There are very few case reports of mixed GCT with extradural spine metastases. We report a rare case of a 17-year-old girl who had undergone left salpingo-oophorectomy with omental and peritoneal biopsy for ovarian GCT with extradural spinal metastasis...

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...

OBJECTIVE: A new treatment principle, which seems to radically change the treatment approach in ovarian cancer (OC), has developed over the past few years. Poly(ADP-ribose) polymerase inhibitors work by interfering with mechanisms important to DNA damage repair. Cancer cells that already have defects in the BRCA genes are particularly sensitive to treatment with poly(ADP-ribose) polymerase inhibitors. The main purpose of this study was to investigate the effect of veliparib in patients with known BRCA1/2 mutations and with a platinum-resistant or intermediate sensitive relapse of OC...

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...

Mature teratomas are the most common ovarian neoplasms, accounting for 40% to 50% of ovarian tumors, and are histologically defined by the presence of multiple lineages of mature differentiated cells derived from one or more of the 3 embryonic germ layers; ectoderm, mesoderm, and endoderm. Neuroectodermal and neural crest differentiation can be observed in mature teratomas, but it is uncommon to find secondary tumors that arise from the neural crest lineage. Herein we report the uncommon finding of a ganglioneuroma arising in a mature cystic teratoma in a 26-yr-old woman...

Although homozygosity is well documented in mature teratomas, the genetic zygosity of ovarian immature teratomas and mixed germ cell tumors is less well studied. Ten cases of mature cystic teratomas, eleven cases of grade 2 or 3 immature teratomas, and seven cases of mixed germ cell tumors with an immature teratoma component were investigated by short tandem repeat genotyping to interrogate their genetic zygosity. DNA genotyping was informative in eight mature teratomas, seven immature teratomas and six cases of mixed germ cell tumors...

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...

Ovarian Sertoli-Leydig cell tumors (SLCTs) are uncommon sex cord-stromal tumors associated with both germ-line and somatic DICER1 mutations, the frequency of which has varied widely in different studies (0% to 62.5%). The current World Health Organization Classification includes 3 histologic types of SLCTs (well-differentiated, moderately differentiated, and poorly differentiated); heterologous elements and/or retiform patterns may be present in moderately and poorly differentiated neoplasms. We investigated the frequency of DICER1 mutations in a series of 38 ovarian tumors initially diagnosed as SLCTs, and explored whether identified mutations were associated with specific morphologic features...

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...
