AbstractAbstract
[en] The radiosensitivity of 4 human ovarian cancer cell lines was investigated in vitro by a clonogenic assay and analyzed using the linear-quadratric model. 2 Cell lines were found to be highly radiosensitive (mean inactivation dose (D-bar) 0.82-0.92 Gy; surviving fraction 2 Gy (SF2)<=0.13). 2 Other cell lines were less sensitive to radiation (D-bar 1.31-1.94 Gy; SF2 0.22-0.38). Although the use of external radiotherapy in ovarian cancer has been limited due to the pattern of metastatic spread of this cancer, the present data support the view that ovarian carcinomas are radiosensitive tumors. Investigations on the effects of new approaches, such as delivering radiation more specifically to intraperitoneal ovarian cancer cells, are warranted. (author). 24 refs.; 4 figs.; 2 tabs

AbstractAbstract
[en] To increase diagnostic efficiency and cost-effectiveness, we performed an exploratory genetic test using a newly designed panel containing 28 actionable and druggable genes, alterations in which are frequently reported in gynecological cancers (TANRE-G, Targeted variants ANalysis RElated to Gynecological cancers). Samples consisted of the formalin-fixed, paraffin-embedded tissue of endometrial (4 cases), cervical (3 cases), and ovarian (4 cases) carcinomas. The sequencing procedure was performed using Ion PGM in our institute with related sequencing kits, and data were analyzed using ClinVar. The present system achieved more than 2500 reads in all tumor samples, and enabled a copy number variation analysis. Results showed that actionable and druggable mutations were detected in 82% (9/11) and 64% (7/11) of cases, respectively, which was similar to other commercially available genetic tests. The amplification of MYC and KRAS was also detected. The analysis cost for each sample was JPY 94,000 (USD 850). These results demonstrate the potential of the TANRE-G panel as an effective tool for examining genetic alterations in gynecological cancers.

AbstractAbstract
[en] Irradiation of advanced ovarian cancer has been performed during the years 1976-1984 with six-field technique. Results of this treatment in a long follow-up have never before been evaluated. Seventy-five patients with stage IIb-IV of invasive ovarian cancer have been treated with a combination of surgery, radiotherapy and chemotherapy. The results of the treatment were compared with 98 patients treated during the year 1991-1992 with surgery and chemotherapy only. After controlling for the differences in background factors between the groups considered, there was still a significantly better survival rate for the patients treated with radiotherapy. The results suggest that the role of radiotherapy in advanced ovarian cancer should be investigated in a prospective randomized trial. (author.)

AbstractAbstract
[en] The role of radiology is of utmost importance not only in diagnosing s-OHSS but also in ruling out other cystic ovarian diseases and to determine the underlying etiology and course of the disease. We presented a radiological algorithm for diagnosing the various causes of s-OHSS. A 26-year-old female, gravida one was referred to radiology department with history of lower abdominal pain, nausea and vomiting since 2 days which was gradual in onset and progression. The patient had no significant medical and surgical history. This article illustrates and emphasizes that diagnosis of s-OHSS and its etiology can be completely evaluated radiologically. Biochemical markers will confirm the radiological diagnosis

AbstractAbstract
[en] Ovarian stromal hyperthecosis is characterized by diffuse distribution of luteinized stromal cells accompanied by varying degrees of stromal hyperplasia. We report a case of ovarian stromal hyperthecosis with particular regard to magnetic resonance (MR)-pathologic correlation. At initial MR imaging, the central areas of the bilateral ovarian masses showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images, while the peripheries of the bilateral masses showed isointensity to myometrium on T1-weighted images and heterogeneous signal intensities on T2-weighted images. At 15 days after the initial MR imaging examination, a second MR imaging demonstrated shrinkage of the bilateral ovarian masses. Change in the peripheries to predominantly isointensity to myometrium on the T2-weighted images was also observed. The patient underwent bilateral oophorectomy. Microscopic examination revealed scattered nests of lutein cells on a background of densely proliferated ovarian stroma with minimal collagen production in both ovaries. Edema was occasionally seen in the outer portion but was marked in the central zone of the ovaries, particularly on the left. The final pathologic diagnosis was stromal hyperthecosis. With regard to MR-pathologic correlation, the MR findings in the peripheries of the bilateral masses (isointensity relative to myometrium on both T1- and T2-weighted imaging) showed the characteristics of stromal hyperthecosis

AbstractAbstract
[en] Introduction: MRI evaluation of parameters of the ovaries for the diagnosis of polycystic ovaries in patients with polycystic ovary syndrome (PCOS). Materials and methods: an MRI of the pelvis was performed in 51 patients with PCOS and 50 healthy volunteers. The volume and maximum diameter of the bigger ovary, the number of follicles, and the maximum diameter and volume of the biggest follicle of the bigger ovary were determined in relation to patient age and were statistically compared. ROC analysis was performed to evaluate the prognostic quality of the parameters of the ovaries regarding the diagnosis of PCOS. Results: in a cohort aged 21 - 30 a significant difference between patients with PCOS and healthy volunteers was able to be determined for all 5 parameters (p < 0.001). In the cohort aged 31 - 40 neither one of the parameters showed a significant difference. In the group of 21 - 30 year-olds the AUC was significantly different from 0.5 in all parameters. The maximum diameter, the volume and the number of follicles of the bigger ovary presented the highest AUC. The parameters needed to diagnose PCOS in MRI in a group of women aged 21 - 30 are a maximum diameter of an ovary of 30 mm, an ovarian volume of 5.6 cm3 and at least 12 follicles. In regard to these parameters a diagnostic sensitivity of 90.32%, 90.32% und 80.65% and a specificity of 68.42%, 63.16% und 86.42% can be reached. (orig.)
