    Bilateral adnexal torsion due to postmenopausal hydatidiform mole
    (WILEY-BLACKWELL, 2011) Ozdemir, Suna; Balci, Osman; Gorkemli, Huseyin; Koyuncu, Tuba; Turan, Gulay
    Occurrence of gestational trophoblastic neoplasia (GTN) and adnexal torsion is rare in postmenopause. We report a 58-year-old postmenopausal woman with adnexal torsion caused by hydatidiform mole. The patient was admitted to our clinic complaining of acute abdominal pain, nausea and vomiting lasting one day. Ultrasonography showed an enlarged uterus including hypo/hyperechogenous cystic areas in the endometrial cavity and bilateral adnexal masses. beta-HCG level was investigated and determined as 157.000 IU/l, because of the suspicion of GTN in ultrasonography. Doppler sonography revealed enlarged left adnexa with absence of vascular flow. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. beta-HCG decreased to normal ranges in the fourth postoperative week. The resected uterus contained an endometrial, cystic, grapelike tumor. The ovaries were enlarged bilaterally with necrotic appearance. Histopathology revealed complete hydatidiform mole and theca lutein cysts. To our knowledge, the present case is the first hydatidiform mole associated with bilateral adnexal torsion caused by theca lutein cysts in postmenopausal period.

    The expression of HER-2/neu (c-erbB2), survivin and cycline D1 in serous ovarian neoplasms: their correlation with clinicopathological variables
    (SPRINGER, 2014) Turan, Gulay; Usta, Ceyda Sancakli; Usta, Akin; Kanter, Mehmet; Tavli, Lema; Karacan, Meric; Celik, Cetin
    Ovarian cancer is the most common cause of death among all gynecologic malignancies and a result of complex interaction of multiple oncogenes and tumor suppressor genes. The aim of this study was to evaluate expression of HER-2/neu (c-erbB2), survivin and cycline D1 biomarkers in serous ovarian neoplasms and their correlations with clinicopathological variables in serous ovarian cancers. We analyzed pathological specimens of 62 patients with benign (n = 25), borderline (n = 14) and malignant (n = 23) serous ovarian neoplasms. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded specimens. Significantly more immunoreactivity with HER-2/neu was detected in malignant tumors (100 %) compared to borderline (78.6 %) and benign tumors (48 %) (P < 0.01). Survivin expression was significantly higher in malignant tumors (91.3 %) than those found in borderline (71.4 %) and benign tumors (24 %) (P < 0.001). Similarly, higher cyclin D1 expression was observed in malignant tumors (95.6 %) compared to borderline (85.7 %) and benign tumors (48 %) (P < 0.001). Expression of all biomarkers analyzed significantly and gradually increased from benign to borderline and borderline to malignant serous tumors. In terms of clinicopathological variables, only tumor grade was associated with the expression of all biomarkers others exhibited different correlations in serous ovarian cancers. The expressions of HER-2/neu (c-erbB2), survivin and cycline D1 are positively correlated with the malignant potential of serous ovarian neoplasms.

    Survivin and cycline D1 expressions are associated with malignant potential in mucinous ovarian neoplasms
    (SPRINGER, 2016) Kanter, Mehmet; Turan, Gulay; Usta, Ceyda; Usta, Akin; Esen, H. Hasan; Tavli, Lema; Celik, Cetin
    The most prevalent malignant ovarian neoplasms are epithelial ovarian cancers which is the most common cause of death among all gynecologic malignancies and a result of complex interaction of multiple oncogenes and tumor suppressor genes. The aim of this study was to evaluate expression of survivin and cycline D1 biomarkers in mucinous ovarian neoplasms and their correlations with clinicopathological variables in mucinous ovarian cancers. We analyzed pathological specimens of 98 patients with benign (n = 34), borderline (n = 22) and malignant (n = 42) mucinous ovarian neoplasms. Immunohistochemical analysis was performed on formalin-fixed paraffin-embedded specimens. Immunohistochemical analysis revealed that survivin and cyclin D1 expressions were located primarily in the nucleus of ovarian tumor cells and relatively weaker cytoplasmic staining. Survivin expression was significantly higher in malignant tumors (88.1 %) than those found in borderline (18.2 %) and benign tumors (8.8 %) (p < 0.001). Similarly, higher cyclin D1 expression was observed in malignant tumors (100 %) compared to borderline (36.4 %) and benign tumors (5.9 %) (p < 0.001). Expression of all biomarkers analyzed significantly and gradually increased from benign to borderline and borderline to malignant mucinous tumors. In terms of clinicopathological variables, tumor grade, FIGO stage and lymph node methastasis were associated with the expression of both biomarkers. Whereas age exhibited no different correlations in mucinous ovarian cancers. The expressions of survivin and cycline D1 are positively correlated with the malignant potential of mucinous ovarian neoplasms.
