Four of 28 patients with borderline tumors of the ovary died of intercurrent disease. Twenty-four are alive without clinical evidence of disease, despite the fact that six of them were stage III; joined with the invasive carcinomas they would distort the survival rates. The development of monoclonal antibodies specific to borderline tumors could improve the value of immunohistochemistry in the diagnosis of borderline tumors. Our results show that the rates of expression of CA 125, CA 19-9, and CEA indicate that borderline tumors are an independent group between benign and malignant ovarian tumors.

After the intravenous injection of a betamimeticum hexoprenaline a significant improvement of the motility of the ureter was noted by intravenous pyelogram in the majority of radically operated patients. In 60.1% of subjects an increase in the frequency as well as a qualitative improvement of contractions was noted. A decrease of motility (22.6%) was never qualitative but ever only quantitative. The incidence of these changes (-28.4%) was significantly less than the improvement (+51.4%). This prospective study was carried out in 136 patients and showed that hexoprenaline (Ipradol) increases the motility of the ureter. This leads to preventive consequences.

CA 125, CA 19-9 and CEA were demonstrated in tissue samples of 30 ovarian borderline tumors by immunohistochemistry. Of the 21 serous and 9 mucinous borderline tumors, 23 were in stage I and 7 stage III. None of the patients died of disease. All mucinous borderline tumors were CA 125 negative, 89% CA 19-9 positive and 44% CEA positive. 62% of the serous borderline tumors were CA 125 positive, 52% CA 19-9 and 19% CEA positive. Tumors of low malignant potential responded to CA 19-9 like invasive carcinomas. The incidence of positive responses to CA 125 ands CEA fell between that of benign and malignant tumors. The marker pattern did not correlate with tumor stage and cytological grading. The biological behavior of ovarian borderline tumors ranges between that of benign tumors and invasive carcinomas and cannot be classified as definitely belonging to either group. It is plausible that they are primarily of the borderline type, and not benign tumors that undergo malignant degeneration.

The incidence of clavicula fractures at the First Department of Obstetrics and Gynecology of the University of Vienna was 217/8383 (2,6%) deliveries in 1980 through 1984, whereas 248/5531 (4,44%) deliveries were noted at LKH Mödling. Higher birth weight and larger children result in a greater incidence of clavicula fractures. The greater percentage of children weighing more than 4000 gm and being larger than 52 cm at the LKH Mödling compared to that at the First Department of Obstetrics and Gynecology of the University of Vienna, i.e. 18,55% and 40,32% vs. 15,67% and 28,57%, resp. explains the higher incidence of clavicula fractures there.

In a prospective study covering 175 gravidae it was investigated whether the risk of a "small" placenta could be detected by determining HPL or serum estriol once during the first 18 weeks of pregnancy. The results show that neither the HPL value nor the serum estriol value correlate with the weight of the placenta or the child. Therefore, the problem of early detection of a "small" placenta cannot be resolved with these hormone parameters.

- Abstract
Less than 10 deliveries via cervicovaginal fistula (CVF) with closed cervical os were reported so far. In the majority of cases, the patients had a history of induced abortions. The CVF was usually recognized due to postpartum hemorrhage. The facilitating role of prostaglandins used for labor induction was supposed. In all cases, the babies remained unaffected by the delivery route. We report a new case of a 37-year-old gravida 2, para 0, with a history of a paracervical tear following a first trimester abortion 11 years ago. The abortion and the laceration were not reported in the current obstetrical documentation. After labor induction using oral misoprostol in the 41 + 5 weeks of pregnancy, the patient delivered a healthy baby through a left-sided CVF, which imposed as bleeding paracervical laceration, 6 cm in diameter, extending to the vaginal fornix in the 3 o'clock position. The cervical os was only 1-1.5 cm dilated and imposed as an inelastic band ("squid ring") in the 9 o'clock position. The laceration was sutured under spinal anesthesia. The patient recovered quickly, and the postpartum hemoglobin drop was 2.8 g/dl. In conclusion, the possibility of CVF should be considered in women with a history of induced abortion.

- Abstract
Objective: Sexual activity (SA) and functioning (SF) are important factors influencing quality of life (QoL). Anticancer treatment can cause or promote sexual dysfunctions. In this study we analyzed the SA, SF and QoL in patients after completion of treatment for breast cancer (BC) and ovarian cancer (OC)., Methods: In this retrospective multicenter study 396 BC patients and 93 OC patients aged between 18 and 70 years were surveyed at least 24 months after cancer diagnosis and compared to 60 healthy women. Data were collected through validated questionnaires (Sexual Activity Questionnaire, Female Sexual Function Index-d, EORTC Quality of Life Questionnaire-C30)., Results: 45.9% of BC patients and 56.5% of OC patients reported SA. SF and well-being of sexually active BC patients were not influenced by the type and radicality of surgery or the administration of chemotherapy. Patients who received antihormonal therapy at the time of evaluation showed a lower frequency of SA (p = 0.007), less satisfaction (p = 0.003) and more discomfort during SA (p = < 0.001) compared to healthy controls but no differences in experiencing orgasms, health status, QoL and global health status. In contrast, BC patients without antihormonal therapy showed only a higher discomfort score (p = 0.028) than healthy controls and estimated their health status and QoL significantly better than patients who received antihormonal therapy (p = 0006). In general, SA was associated with a better health status (p = 0.007), a better QoL (p = 0.004) and a better global health status (p = 0.004) in BC patients. Sexually active OC patients showed no significant differences in SF, QoL and health status compared to healthy controls., Conclusions: Compared to healthy controls BC patients showed limitations in SF with a lower SA rate and more discomfort. Antihormonal therapy was an important factor influencing SF and well-being. Breast and OC survivors reported good physical and psychical health without differences in QoL and health status compared to controls. This might be explained by a change of perspective on life difficulties and altered priorities through a life threatening disease.

- Abstract
Objective: To compare operating time and blood loss in patients undergoing total laparoscopic hysterectomies (TLH) for benign conditions with either the Marseal™ IQ 5 mm (MS) or the Ligasure™ 5 mm (LS) vessel-sealing device., Design and Setting: A randomized controlled clinical trial (RCT) in two German gynecology departments., Patients: 74 patients scheduled to undergo TLH for a symptomatic fibroid uterus, adenomyosis or severe meno-metrorrhagia., Interventions: Patients were randomized to receive a TLH with either the MS or the LS device. 27 variables were prospectively collected to address potential confounding issues., Measurement and Main Results: Operating time, defined as the time period between the first (round ligament dissection) and the last (uterine vessels sealing) use of the device, estimated and calculated intraoperative blood loss. The mean operating time (95% confidence interval, CI) was 22.7 min (95% CI 17.6-27.7) for LS and 26.4 min (95% CI 20-32.8) for the MS device (p = .89). The estimated intraoperative blood loss was 164 ml (95% CI 110-217) for LS and 160 ml (95% CI 116-203) for the MS device (p = .36). The multivariate analyses accounting for BMI, endometriosis, uterine weight and appearance of fibroids did not reveal any significant effect of the type of device used on operating time and estimated blood loss., Conclusion: In this RCT, both devices provided reliable and effective sealing and dissection. The reusable MS showed non-inferiority against the disposable LS device with regard to operating time and estimated intraoperative blood loss.

- Abstract
Background: The effective utilization of staff resources is of decisive importance for the adequate, appropriate, and economical delivery of hospital services. The goal of this study was to determine the distribution of working time among doctors in a German university hospital-in particular, in terms of type of activities and time of day., Methods: The distribution of working time was determined from 14-day samples taken in seven clinical departments of the Medical Center-University of Freiburg. In each 14-day sample, the activities being carried out at multiple, randomly chosen times were recorded., Results: A total of 250 doctors (participation rate: 83%) took part in the study. A total of 20 715 hours of working time was analyzed, representing twelve years of full-time employment. Overall, 46% of working time in the inpatient sector was spent in direct contact with patients, with relevant differences among the participating clinical departments: for instance, the percentage of time taken up by patient contact was 35% in pediatrics and 60% in oral and maxillofacial surgery. Patient contact was highest (over 50% overall) in the period 8 a.m. to 12 noon., Conclusion: The amount of working time taken up by activities other than direct patient contact was found to be lower than in previous studies. It remains unclear what distribution of working time is best for patient care and whether it would be possible or desirable to increase the time that doctors spend in direct contact with patients.

- Abstract
Objective: The aim of this study was to calculate the validity parameters of the Digene Hybrid Capture 2 (HC2) high-risk human papillomavirus DNA test with and without cytology in the follow-up examinations after laser treatment of the transformation zone or large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia (CIN)., Methods: We performed a standardized follow-up examination in 113 postlaser and 153 post-LLETZ patients in our colposcopy clinic. Routine cytology, HC2 tests, and colposcopically-guided cervical biopsies were performed and sensitivity, specificity, and positive and negative predictive values were calculated using the histological cervical biopsy result as the criterion standard., Results: After a median follow-up time of 25.5 months, the overall posttreatment recurrence/persistence rate of CIN 2 or higher (CIN 2+) was 24% after laser and 12.4% after Post-LLETZ treatment. Hybrid Capture 2 alone had a sensitivity/NPV of 70/88% in post-laser and 70/93% in post-LLETZ patients. Cytology alone had a sensitivity/NPV for CIN 2+ of 48/84% in post-laser and 58/91% in post-LLETZ patients. Combined testing of HC2 with cytology had a sensitivity/NPV of 81/92% in postlaser and 88/95% in post-LLETZ patients., Discussion: In this test of cure study, combined testing of cytology with HC2 resulted in a high sensitivity and NPV. Hybrid Capture 2 and cytology-negative women may safely return to routine recall. Cytology alone is not an adequate follow-up strategy in postlaser patients.

- Abstract
Due to their post-transcriptional regulatory impact on gene expression, microRNAs (miRNA, miRs) influence decisively cellular processes of differentiation, proliferation and apoptosis. In oncogenic pathways various miRNAs exert either oncogenic or tumor suppressor activities in a stage-specific manner. Dysregulation of miRNA expression pattern has been associated with several human cancers including endometrial cancer (EC). In the present study, expression profile alterations of EC associated secreted miRNAs were determined under the microenvironmental stress situations hypoxia and acidosis occurring in tumor progression and metastasis. The potential influence of hypoxia and acidosis vs. control conditions on the expression levels of 24 EC-relevant miRNA types was quantitatively accessed via real-time PCR in three established EC in vitro models. Expression data were analyzed statistically. In vitro application of hypoxia resulted in downregulation of miR-15a, miR-20a, miR-20b and miR-128-1 in Ishikawa cells (type I EC) and upregulation of miR-21 in EFE-184 cells (type I EC). Acidosis triggered upregulation of tumor promoting miR-125b in AN3-CA cell (type II EC), whereas in Ishikawa cells (type I EC) miRNAs with tumor suppressive function were found altered in divergent directions, both up- (let-7a) and down- (miR-22) regulated. Our current findings emphasize the functional importance of secreted miRNAs in the immediate response of EC cells to exogenic stress situations such as the typical tumor epiphenomena hypoxia and acidosis. Focusing on the specific potential of secreted, thus circulating miRNA molecules, alterations in expression levels not only influence intracellular gene expression and signaling cascades, but also transfer the induction of (tumor)biological cellular changes to adjacent cells.

- Abstract
Tumor resistance to endocrine therapy triggers estrogen-independent cancer progression, which is a major obstacle to the successful treatment of hormone receptor positive breast cancer (BC). The underlying molecular mechanisms of endocrine resistance are not fully understood yet. The matricellular protein cysteine-rich angiogenic inducer 61 (Cyr61) is associated with tumor invasiveness and the induction of tumorigenesis in various malignancies in vivo and the induction of estrogen-independence and endocrine therapy resistance in BC. The present study evaluated the potential effects and clinical relevance of Cyr61 expression levels in 67 patients with primary non-metastatic BC. Immunohistochemical analysis of formalin-fixed paraffin-embedded tissue sections was performed, and the association between Cyr61 protein expression and clinicopathological factors and survival was analyzed. Cyr61 overexpression was revealed to be significantly associated with a positive estrogen receptor (ER)/progesterone receptor (PR) status (P=0.016) and to the molecular subtype of BC (P=0.039). Compared with patients without Cyr61 overexpression, patients with Cyr61 overexpression exhibited an increased recurrence rate (30.6 vs. 22.6%) and decreased long-term survival (10-year overall survival, 62.9 vs. 69.7%); however, these associations did not reach statistically significant levels in Cox regression model analysis. Similar results were identified in the subgroup analysis of patients with ER/PR positive BC. These results indicate that Cyr61 serves a role in the development of endocrine therapy resistance in BC and is thus a potential therapeutic target to overcome endocrine therapy resistance. However, additional long-term survival analyses with large patient populations are required.

- Abstract
Background/aim: The pro-angiogenic Cyr61 protein has been associated with tumorigenesis and cancer progression in different gynecological carcinomas. In this study, we evaluated the potential impact and clinical relevance of Cyr61 expression in patients with primary non-metastatic cervical cancer (CC)., Patients and Methods: Cyr61 expression was assessed in tissue specimen of 48 patients with primary CC by immunohistochemical analysis. Expression levels were scored and correlated to clinico-pathological factors and outcome data., Results: High Cyr61 expression levels were present in 54.2% of CC tissues. Associations with histological grade (p=0.030), depth of tumor invasion (p=0.007) and GOG score (p=0.027) were observed. Patients who overexpressed Cyr61 displayed an increased death rate (30.8% vs. 18.2%) and a decreased 5-year-survival (76.9% vs. 86.4%)., Conclusion: Our data indicate a potential functional impact of Cyr61 in development and the progression of CC. The definite tumor-relevant function (suppressive/promoting) of Cyr61 in CC and the prognostic relevance of Cyr61 overexpression has to be evaluated in larger cohorts., (Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

- Abstract
Objective: In recurrent ovarian cancer (ROC), there is a high demand on effective therapies with a mild toxicity profile. Treosulfan is an alkylating agent approved as oral (p.o.) and intravenous (i.v.) formulation for the treatment of recurrent ovarian cancer. Data on safety and efficacy for either formulation are rare. For the first time we conducted a randomized phase III study comparing both formulations in women with ROC., Methods: Patients having received at least two previous lines of chemotherapy were randomly assigned to one of two treatment arms: treosulfan i.v. 7000 mg/m
2 d1 q4w or treosulfan p.o. 600 mg/m2 d1-28 q8w. Primary endpoint was safety regarding hematological and gastrointestinal toxicity grade III/IV, secondary endpoints were other toxicities, clinical benefit rate (CBR), time to progression (TTP), overall survival (OS) and quality of life., Results: 250 patients were treated with treosulfan i.v. (128) or treosulfan p.o. (122). In general treosulfan therapy was well tolerated in both treatment arms. Leukopenia grade III/IV occurred significantly more frequently in the p.o. arm (3.9% i.v. arm, 14.8% p.o. arm, p = 0.002). Other toxicities were similar in both arms. CBR was comparable between arms (41.4% i.v. arm, 36.9% p.o. arm). No difference in TTP (3.7 months i.v. arm, 3.5 months p.o. arm) or OS (13.6 months i.v. arm, 10.4 months p.o. arm, p = 0.087) occurred., Conclusions: Given the safety and efficacy results treosulfan is an acceptable option for heavily pretreated OC patients. Regarding the toxicity profile the i.v. application was better tolerated with less grade III and IV toxicities., Competing Interests: Compliance with ethical standardsConflict of interestJalid Sehouli declares that he received an educational grant from medac.

- Abstract
Introduction: Lesions of uncertain malignant potential (B3) represent a heterogeneous group with an overall risk for malignancy of 9.85-35.1% after total resection. Positive predictive values (PPV) for malignancy vary depending on B3 subtype. The aim of this study was to evaluate the PPV for malignancy in B3 lesions and to determine the clinical significance of atypia-dependent sub-classification (a = without epithelial atypia; b = with epithelial atypia) of B3 into B3a and B3b and papillary lesions (PL) in PLa and PLb., Methods: 219 patients with histopathologically proven B3 lesions on core needle/vacuum-assisted biopsy who subsequently underwent diagnostic excision biopsy were included in this study. PPVs for malignancy were reported for B3 in general and all B3 sub-categories. Logistic regression analysis identified associations between B3-subgroups and outcome after excision biopsy as well as the impact of clinical and diagnostic findings on excision diagnosis., Results: The overall PPV rate was 10.0% (22/219). Excision histology exhibited a higher malignancy rate in PLb (2/7; PPV: 28.6%) than in PLa (6/127; PPV: 4.7%) (p = 0.057) and in B3b (12/50; PPV: 24.0%) compared to B3a category (8/165; PPV: 4.8%) (p < 0.001)., Discussion: These findings support the necessity of B3 lesion sub-classification into B3a and B3b and of PL into PLa and PLb when considering epithelial atypia. The determination of atypia status represents a relevant factor in risk-stratification for clinical management of B3 lesions. Should future studies using the sub-classification of PL confirm these results, observation may be a safe option for the clinical management of patients with asymptomatic PLa lesions., (Copyright © 2016 Elsevier Ltd.

Purpose: Expression profile alterations of nine breast cancer (BC)-associated secreted microRNAs (miRs) were determined under microenvironmental alterations occurring in tumour progression, metastasis or specific oncological treatment modalities. Thereto, the potential influence of the exogenic stimuli hypoxia, acidosis and hyperthermia was investigated in vitro., Material and Methods: Four established BC cell lines were applied as in vitro BC model systems. Quantitative analyses of secreted microRNA specimens were performed by RNA isolation from cell culture supernatant and subsequent real-time PCR in cells under physiological versus hypoxic, acidic or hyperthermia conditions., Results: The in vitro application of exogenic stimuli hypoxia, extracellular acidosis and hyperthermia caused heterogeneous expression alterations for the investigated secreted miRNA phenotypes. The majority of relevant exogenic stimuli-dependent microRNA expression alterations were restricted to single events displaying distinct cell type and stimulus dependent correlations only. Most remarkably, hyperthermia triggered a uniform significant down-regulatory effect on the expression levels of the three secreted microRNAs miR-10b, miR-15b and miR-139, respectively. The marked decrease in miR-10b and miR-15b levels was detectable in all four, while miR-139 was found significantly reduced in three out of four BC cell lines., Conclusion: Hyperthermia-dependent down-regulatory influence on three distinct BC-related microRNAs in vitro generates translational aspects for clinical BC treatment, since the identified microRNAs miR-10b, miR-15b and miR-139 are known to have oncogenic as well as tumour suppressor functions in BC. However, an evaluation regarding the potential impact of microRNA-related hyperthermia-dependent alterations for innovative BC treatment approaches demands further analysis including in vivo data.

- Abstract
Introduction: There is only limited data from clinical practice on the relevance of body mass index (BMI) on pathologic complete response (pCR) following neoadjuvant chemotherapy (NAC) in patients with breast cancer (BC)., Patients and Methods: The impact of BMI on pCR and survival outcome was examined in 324 patients with primary non-metastatic BC. An additional meta-analysis was performed on the current data and relevant previously published studies in clinical practice., Results: Multivariable regression analysis identified lymph vascular invasion (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.01-0.18; P = .0000), grading 3 (OR, 3.12; 95% CI, 1.59-6.12; P = .0009), and HER2/neu status (OR, 4.76; 95% CI, 1.86-12.18; P = .011) as independent factors for pCR after NAC. There was no association between pCR and continuous or categorical BMI. Various additional subgroup analyses of molecular BC subtypes (triple-negative, luminal-like, HER2-luminal, HER2-like) and BMI also showed no association. These findings were confirmed by the meta-analysis. Except for one subgroup analysis in which overweight and obese patients were combined as one group, no association between BMI and pCR as well as survival outcome was found., Conclusions: BMI was not established as a relevant clinical factor. Only lymph vascular invasion, grading 3, luminal-like, and HER2/like BC subtype showed predictive and prognostic impact in patients with BC receiving NAC., (Copyright © 2016 Elsevier Inc.

- Abstract
Introduction: The gastrin-releasing peptide receptor (GRPR) is overexpressed in breast cancer. The present study evaluates GRPR imaging as a novel imaging modality in breast cancer by employing positron emission tomography (PET) and the GRPR antagonist (68)Ga-RM2., Methods: Fifteen female patients with biopsy confirmed primary breast carcinoma (3 bilateral tumors; median clinical stage IIB) underwent (68)Ga-RM2-PET/CT for pretreatment staging. In vivo tumor uptake of (68)Ga-RM2 was correlated with estrogen (ER) and progesterone (PR) receptor expression, HER2/neu status and MIB-1 proliferation index in breast core biopsy specimens., Results: 13/18 tumors demonstrated strongly increased (68)Ga-RM2 uptake compared to normal breast tissue (defined as PET-positive). All PET-positive primary tumors were ER- and PR-positive (13/13) in contrast to only 1/5 PET-negative tumors. Mean SUVMAX of ER-positive tumors was 10.6±6.0 compared to 2.3±1.0 in ER-negative tumors (p=0.016). In a multivariate analysis including ER, PR, HER2/neu and MIB-1, only ER expression predicted (68)Ga-RM2 uptake (model: r(2) =0.55, p=0.025). Normal breast tissue showed inter- and intraindividually variable, moderate GRPR binding (SUVMAX 2.3±1.0), while physiological uptake of other organs was considerably less except pancreas. Of note, (68)Ga-RM2-PET/CT detected internal mammary lymph nodes with high (68)Ga-RM2 uptake (n=8), a contralateral axillary lymph node metastasis (verified by biopsy) and bone metastases (n=1; not detected by bone scan and CT)., Conclusion: Our study demonstrates that (68)Ga-RM2-PET/CT is a promising imaging method in ER-positive breast cancer. In vivo GRPR binding assessed by (68)Ga-RM2-PET/CT correlated with ER expression in primary tumors of untreated patients.

- Abstract
There is increasing evidence that not only the way of data acquisition but also the design of data visualization (i.e., the format) has impact on the quality of pathology reports. Therefore, we investigated the correlation between the format of pathology reports and the amount as well as the detection time of transmitted data. All reports of oncological breast resection specimens referred to the Institute for Surgical Pathology, University Medical Center Freiburg, between 2003 and 2011 (n = 4181) were classified into descriptive reports (DR, n = 856), structured reports (SR, n = 2455), or template-based synoptic reports (TBSR, n = 870). The reports were screened regarding the content of nine organ-specific essential data. The amount of recorded essential data per report was summarized in an essential data score (EDS) and the format types were statistically compared regarding their EDS. Additionally, we measured the time a gynecologist needed to detect all nine essential data within a subset of reports and compared the format types regarding the detection times statistically. A full-score EDS of 9 was seen in 28.4 % of all reports, in 4 % of DRs, in 21.4 % of SRs, and in 72.3 % of TBSRs (p < 0.0001). Median EDS of DRs was 7, of SRs 8, and of TBSRs 9 (p < 0.0001). Data regarding tumor localization, tumor size, specific grading, angioinvasion, hormone receptor status, and additional findings were mentioned more frequently in TBSRs compared to other format type reports with a statistically highly significant difference (p < 0.0001). Mean data detection time decreased significantly from 26 to 20 and 14 s in DRs, SRs, and TBSRs, respectively. Our results clearly show that due to the use of TBSRs reporting of oncological breast resection specimens are improved regarding the content of essential data and the clarity of the data layout resulting in a rapid detection of essential data by clinicians.

- Abstract
Objective: The objective of this retrospective study was to analyze the experience with intraoperative radiation therapy (IORT) at the present institution and to evaluate its contribution to the management of patients with recurrent gynecological cancer. Materials and, Methods: Retrospectively this study reviewed data of patients with a gynecological malignancy considered for treatment with IORT at Freiburg University Medical Center between 2005 and 2012. For this purpose, an analysis of medical records, radiation oncology records, operation reports, and follow-up data was conducted., Results: During the period of this study, 31 women with gynecological cancer underwent tumor resection in combination with IORT. The median age of the patients at the time of IORT was 62 years (range 38-85). Most patients had undergone surgery at the time of initial diagnosis (87%). More than one-third of the patients received prior radiation therapy. In addition to that, 52% of the patients had already received chemotherapy. The majority of patients suffered from the first relapse of their disease. The local recurrence was predominantly located at the pelvic side wall (32%) or in intra-abdominal lymph nodes (32%). In 12 patients the authors did not apply the planned IORT. Intraoperative complications were rare and IORT was tolerated without severe side-effects. Follow-up was 14 months (range 1-65), progression free survival (PFS) was five months (range 3-31)., Conclusions: In carefully selected patients, IORT and cytoreductive surgery contributed to local control and disease palliation. The authors therefore consider IORT an important aspect of modern cancer treatment.

- Abstract
Background: Since recent studies revealed the feasibility to detect blood-based microRNAs (miRNAs, miRs) in breast cancer (BC) patients a new field has been opened for circulating miRNAs as potential biomarkers in BC. In this pilot study, we evaluated to our knowledge for the first time whether distinct pattern of urinary miRNAs might be also applicable as innovative biomarkers for BC detection., Methods: Urinary miRNA expression levels of nine BC-related miRNAs (miR-21, miR-34a, miR-125b, miR-155, miR-195, miR-200b, miR-200c, miR-375, miR-451) from 24 untreated, primary BC patients and 24 healthy controls were quantified by realtime-PCR. The receiver operating characteristic analyses (ROC) and logistic regression were calculated to assess discriminatory accuracy., Results: Significant differences were found in the expression of four BC-associated miRNAs quantified as median miRNA expression levels. Urinary miR-155 levels were significantly higher in BC patients compared to healthy controls (1.49vs.0.25; p < 0.001). In contrast, compared to healthy controls, BC patients exhibited significantly lower urinary expression levels of miR-21 (2.27vs.5.07; p < 0.001), miR-125b (0.71vs.1.62; p < 0.001), and miR-451 (0.02vs.0.59 p = 0.004), respectively. The ROC including all miRNAs as well as the group of the four significant deregulated miRNAs separated BC patients from healthy controls with a very high (area under the receiver operating characteristic curve [AUC] = 0.932) and high accuracy (AUC = 0.887), respectively., Conclusions: We were able to demonstrate for the first time the feasibility to detect distinct BC-dependent urinary miRNA profiles. The expression levels of four urinary miRNAs were specifically altered in our cohort of BC patients compared to healthy controls. This distinct pattern offers the possibility for a specific discrimination between healthy women and primary BC patients. This sustains the potential role of urinary miRNAs as non-invasive innovative urine-based biomarkers for BC detection.

- Abstract
Purpose: When counseling patients about surgical alternatives for pelvic organ prolapse (POP) repair, numerous things have to be considered. Uterine preservation vs. hysterectomy is one relevant issue. Hysterectomy has been traditionally performed for POP, but its benefit regarding outcome has never been proven. Furthermore, a growing number of women ask for uterine preservation., Methods: In this retrospective cohort study, 384 patients who had undergone surgery for POP between 2000 and 2012 at Freiburg University Medical Center were included. Using a standardized questionnaire, further surgeries, urinary incontinence, recurrent POP, pessary use, and satisfaction with the surgical outcome were evaluated. The functional results after uterine preservation vs. concomitant hysterectomy were compared using t test., Results: 196 (51.04%) women were available for follow-up and agreed to participate (n = 122 with hysterectomy, n = 72 with uterine-preserving surgery, respectively). After a mean follow-up time of 67 months, vaginal bulge symptoms and urinary incontinence did not differ between treatment groups. We observed higher success rates and satisfaction scores in the uterine-preserving group. Regarding satisfaction with surgery and whether the patients thought it had been successful, we observed a trend toward better results in the uterine-preserving group (mean satisfaction score: 8.45 ± 2.15 vs. 7.76 ± 2.91, range 0-10, p = 0.061; success: 91.4 vs. 81.7 %, p = 0.087)., Conclusions: There was no difference with regard to functional outcome between patients with or without concomitant hysterectomy. Satisfaction with the operation was slightly higher after uterus preserving surgery. Therefore, uterine-preserving surgery is a valuable option unless there are contraindications.

- Abstract
Background: Neoadjuvant chemotherapy (NC) is an established therapy in breast cancer, able to downstage positive axillary lymph nodes, but might hamper their detectibility. Even if clinical observations suggest lower lymph node yield (LNY) after NC, data are inconclusive and it is unclear whether NC dependent parameters influence detection rates by axillary lymph node dissection (ALND)., Methods: We analyzed retrospectively the LNY in 182 patients with ALND after NC and 351 patients with primary ALND. Impact of surgery or pathological examination and specific histomorphological alterations were evaluated. Outcome analyses regarding recurrence rates, disease free (DFS) and overall survival (OS) were performed., Results: Axillary LNY was significantly lower in the NC in comparison to the primary surgery group (median 13 vs. 16; p < 0.0001). The likelihood of incomplete axillary staging was four times higher in the NC group (14.8% vs. 3.4%, p < 0.0001). Multivariate analyses excluded any influence by surgeon or pathologist. However, the chemotherapy dependent histological feature lymphoid depletion was an independent predictive factor for a lower LNY. Outcome analyses revealed no significant impact of the LNY on local and regional recurrence rates as well as DFS and OS, respectively., Conclusion: NC significantly reduces the LNY by ALND and has profound effects on the histomorphological appearance of lymph nodes. The current recommendations for a minimum removal of 10 lymph nodes by ALND are clearly compromised by the clinically already established concept of NC. The LNY of less than 10 by ALND after NC might not be indicative for an insufficient axillary staging.

- Abstract
Objective: Alternative splicing represents an important nuclear mechanism in the posttranscriptional regulation of gene expression, which is frequently altered during tumorigenesis. Previously, we described marked changes in alternative splicing of the CD44 gene in ovarian and breast cancer as well as specific induction of distinct splicing factors during tumor development. The present study was focused on the expression profiles of different splicing factors, including classical serine-arginine (SR) proteins including ASF/SF2, hTra2β1, hTra2α, and Y-box-binding protein (YB-1) in physiological and malignant epithelial ovarian tissue to evaluate their expression pattern with regard to tumor development and disease progression., Materials and Methods: Expression levels of the different splicing factors were analyzed in physiological epithelial ovarian tissue samples, primary tumors, and metastatic samples of patients with a diagnosis of epithelial ovarian cancer using quantified reverse transcription polymerase chain reaction analysis. We examined more closely the splicing factor hTra2β1 using Western blot analysis and immunohistochemistry., Results: The analysis revealed a marked and specific induction of ASF/SF2, SRp20, hTra2β1, and YB-1 in primary tumors as well as in their metastatic sites. However, in our patient cohort, no induction was seen for the other investigated splicing factors SRp55, SRp40, and hTra2α., Conclusions: Our results suggest a specific induction of distinct splicing factors in ovarian cancer tumorigenesis. The involvement of hTra2β1, YB-1, SRp20, and ASF/SF2 in exon recognition and alternative splicing may be important for gene regulation of alternatively spliced genes like CD44 with potential functional consequences in this tumor type leading to progression and metastasis.

- Abstract
Background: Cancer-testis antigens (CTA) comprise a family of proteins, which are physiologically expressed in adult human tissues solely in testicular germ cells and occasionally placenta. However, CTA expression has been reported in various malignancies. CTAs have been identified by their ability to elicit autologous cellular and or serological immune responses, and are considered potential targets for cancer immunotherapy. The breast differentiation antigen NY-BR-1, expressed specifically in normal and malignant breast tissue, has also immunogenic properties. Here we evaluated the expression patterns of CTAs and NY-BR-1 in breast cancer in correlation to clinico-pathological parameters in order to determine their possible impact as prognostic factors., Methods: The reactivity pattern of various mAbs (6C1, MA454, M3H67, 57B, E978, GAGE #26 and NY-BR-1 #5) were assessed by immunohistochemistry in a tissue micro array series of 210 randomly selected primary invasive breast cancers in order to study the diversity of different CTAs (e.g. MAGE-A, NY-ESO-1, GAGE) and NY-BR-1. These expression data were correlated to clinico-pathological parameters and outcome data including disease-free and overall survival., Results: Expression of at least one CTA was detectable in the cytoplasm of tumor cells in 37.2% of the cases. NY-BR-1 expression was found in 46.6% of tumors, respectively. Overall, CTA expression seemed to be linked to adverse prognosis and M3H67 immunoreactivity specifically was significantly correlated to shorter overall and disease-free survival (p=0.000 and 0.024, respectively)., Conclusions: Our findings suggest that M3H67 immunoreactivity could serve as potential prognostic marker in primary breast cancer patients. The exclusive expression of CTAs in tumor tissues as well as the frequent expression of NY-BR-1 could define new targets for specific breast cancer therapies.

- Abstract
Objectives: The aim of this study was to assess the influence of video-assisted thoracic surgery (VATS) on our treatment decisions in FIGO III and IV ovarian cancer patients., Methods: Patients with ovarian cancer and suspected supra-diaphragmatic involvement (pleural effusions, pleural carcinomatosis, lung metastasis, or enlarged supra-diaphragmatic lymph nodes) at chest computer tomography (CT) scan underwent VATS with or without laparoscopy (LSC) to decide for primary cytoreduction or neoadjuvant chemotherapy. Operation time, VATS complications (intrapleural hematoma, secondary hemorrhage with intervention, pneumonia and empyema) and shift in the therapeutic strategy due to VATS were evaluated., Results: 17 patients were included into this study (1 patient with FIGO stage IIIb, 1 with IIIc and 15 with stage IV). The median operation time for VATS only was 46.5 min (range: 20-50 min, n=3). Perioperatively, no complications occurred. After surgical staging, the tumor was confined to the abdomen in four patients in whom primary cytoreduction was attempted. All other 13 patients underwent neoadjuvant chemotherapy. VATS altered the therapeutic management in 6/17 ovarian cancer patients (3 times upstaging, 3 times downstaging). Negative predictive values (NPV) for local and diffuse pleural carcinomatosis ranged between 0.5 and 0.71., Conclusion: In this case series, VATS in addition to LSC showed negligible morbidity related to surgery and a short operation time. We were able to improve the accuracy of the FIGO staging and assessed operability more reliably in these patients than through imaging techniques alone., (Copyright © 2012.

- Abstract
Alteration of gene expression profiles during chemotherapy may predict response to neoadjuvant chemotherapy (NAC) in breast cancer patients. In a prospective cohort study of 32 women with primary invasive breast cancer, we obtained tumor specimens before and after 4 cycles of NAC with epirubicine 90 mg/m2 and cyclophosphamide 600 mg/m2, followed by 4 cycles of docetaxel 100 mg/m2. Total-RNA was extracted from tumor specimens and the whole transcriptome was analyzed with Agilent's 44K single color microarray. Data analysis was performed by GeneSpring v.11 and IBM SPSS v.18. Ten tumors were classified as basal-like and 22 tumors were classified as non-basal-like. Gene expression-based molecular subtype (basal-like vs. non-basal-like) (P=0.003), but not tumor grade (P=0.07), estrogen receptor (P=0.1), progesterone receptor (P=0.6) and HER2 status (P=0.4) predicted pathological complete response to NAC. Specifically, 7/10 basal-like tumors responded to NAC, whereas 19/22 non-basal-like tumors did not respond. Comparing gene expression signatures before and after 4 cycles of NAC, we found that all patients with an initial non-basal-like tumor retained this tumor type, whereas 5/7 basal-like tumors, including all responders, lost this molecular subtype. Complete prediction of response to NAC was achieved with a 21 gene list (P=0.000008). Of note, both the expression and up-regulation of a single gene, i.e. HER4, predicted the response to NAC in 26/32 (81%; P=0.002) and in 23/25 (92%; P<0.001) patients, respectively. These preliminary data indicate that therapy-induced HER4 gene up-regulation may be associated with response to NAC with epirubicine, cyclophosphamide and docetaxel.

The matricellular protein Cysteine rich 61 (Cyr61) displays a remarkable diversity of multiple cellular functions involved in significant physiologic and pathologic processes. Cyr61 is known as an important player in tumor progression, promoting neovascularization and metastasis. Our prior investigations elucidated an oxygen-dependent Cyr61 alternative splicing process characterized by retention of its intron 3, regulating its biological function in a hypoxia-driven on/off switch mechanism. In this work, we identified extracellular acidosis as a potent inducer for altered Cyr61 alternative splicing pattern regulating Cyr61 expression. Intriguingly, splicing factor hTRA2-beta1 displayed an opposite effect on Cyr61 expression. Nuclear hTRA2-beta1 protein expression was found markedly reduced under acidic conditions. In keeping with these conclusions, we show that hTRA2-beta1 can specifically bind a 'GAAG' motif in Cyr61 exon 3 RNA, that the splicing factor displays acidosis-dependent protein localization in cellular compartments, and shRNA-mediated hTRA2-beta1 knock-down triggers the same effects on Cyr61 alternative splicing like acidosis or hypoxia. Our findings strongly support the hypothesis of a specific regulation of Cyr61 expression by hTRA2-beta1.

- Abstract
Objective: Recent evidence suggests equivalent efficacy in terms of local control for adjuvant vaginal brachytherapy (VBT) compared to external beam radiotherapy after surgery in patients with intermediate-high endometrial cancer. The objective of this study is to compare the quality of life (QoL) and sexual function of women with endometrial cancer that were treated with either surgery alone or surgery in combination with postoperative VBT., Methods: Women were interviewed at least 5 years after initial treatment for endometrial cancer. QoL was evaluated by using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 and the cervical cancer module, CX-24. Sexual function was evaluated by using the Female Sexual Function Index (FSFI). Eligible women had early stage disease, were currently disease-free, and had undergone surgery and adjuvant VBT, but neither external beam radiotherapy nor systemic treatment. This study group were then compared using univariate and multivariate analyses with an age-matched control group comprising of endometrial cancer patients without adjuvant VBT., Results: Fifty-five patients (29 surgery plus VBT and 26 surgical controls without VBT) were included for analysis. With respect to QoL including, e.g., physical, role, emotional and social functioning and likewise in terms of sexual function univariate and multivariate analyses did not show significant differences between patients with VBT and the controls without VBT of any of the outcome measures., Conclusion: Adjuvant VBT after surgery does not seem to have a significant impact on quality of life and sexual function in endometrial cancer survivors., (Copyright © 2010 Elsevier Inc.

- Abstract
Background: An increasing proportion of patients are exposed to anthracyclines and/or taxanes in the adjuvant or neoadjuvant setting. Re-exposure in the metastatic stage is limited by drug resistance, thus evaluation of non-cross-resistant regimens is mandatory., Methods: Anthracycline-pretreated patients were randomly assigned to three gemcitabine-based regimens. Chemotherapy consisted of gemcitabine 1.000 mg m(-2) plus vinorelbin 25 mg m(-2) on days 1+8 (GemVin), or plus cisplatin 30 mg m(-2) on days 1+8 (GemCis), or plus capecitabine 650 mg m(-2) b.i.d. orally days 1-14 (GemCap), q3w. The primary end point was response rate., Results: A total of 141 patients were recruited on the trial. The overall response rates were 39.0% (GemVin), 47.7% (GemCis) and 34.7% (GemCap). Median progression-free survival was estimated with 5.7, 6.9 and 8.3 months, respectively. Corresponding median survival times were 17.5 (GemVin), 13.0 (GemCis) and 19.4 months (GemCap). Neutropenia ≥grade 3 occurred in 16.7% (Gem/Vin), 4.4% (GemCis) and 0% (Gem/Cap), whereas non-haematological toxicities were rarely severe except grade 3 hand-foot syndrome in 2.0% of the GemCap patients (per patient analysis)., Conclusions: This randomised phase II trial has revealed comparable results for three gemcitabine-based regimens regarding treatment efficacy and toxicity. Gemcitabine-based chemotherapy appears to be a worthwhile treatment option for pretreated patients with metastatic breast cancer.

- Abstract
Objective: To compare the efficacy of the new reusable vessel-sealing device MarSeal (KLS Martin, Tuttlingen, Germany) with the conventional standard disposable LigaSure device (Covidien-Valleylab, Boulder, CO) in an in vivo animal model., Design: Prospective animal study., Setting: Center of Experimental Surgery at a university hospital., Animals: Thirteen sheep., Intervention(s): The carotid and femoral arteries were dissected bilaterally and sealed randomly with MarSeal unilaterally and consecutively with LigaSure contralaterally in vivo. Afterward the burst pressure was determined for each artery., Main Outcome Measure(s): Sealing time, failure rate, and burst pressure., Result(s): The mean diameter of all arteries sealed did not differ significantly between the two groups (MarSeal 5.40 mm vs. LigaSure 5.35 mm). The mean sealing time was significantly shorter with use of the reusable device (MarSeal 5.2 seconds vs. LigaSure 9.1 seconds). We did not find a significant difference in sealing failure rates between the groups (MarSeal 7.0% vs. LigaSure 9.1%). In addition, analysis of mean burst pressure did not reveal a significant difference between the different devices (MarSeal 429 mm Hg vs. LigaSure 484 mm Hg). There was no significant difference with respect to lateral thermal damage (MarSeal 0.91 cm vs. LigaSure 0.93 cm)., Conclusion(s): In our in vivo animal study, the new reusable MarSeal device appears to be equivalently effective for vessel sealing when compared with the conventional disposable LigaSure device., (Copyright © 2011 American Society for Reproductive Medicine.

- Abstract
Background: In order to decrease surgery-related morbidity, we evaluated the reliability of the evaluation of lymph node metastasis in patients with uterine corpus cancer by positron-emission tomography (PET) with 2-[(18)F]fluoro-2-deoxy-D-glucose (FDG) before surgical staging., Materials and Methods: Patients with newly diagnosed uterine corpus cancer scheduled for surgical staging, including lymphadenectomy, underwent PET imaging within 30 days before surgery. PET results and postoperative histopathology were compared for each patient and each nodal site. Sensitivity, specificity, positive and negative predictive value (PPV/NPV) as well as accuracy of FDG-PET in predicting nodal disease was determined by joined meta-analysis of the present data and the data available in the literature., Results: Of 21 patients examined, 13 patients were eligible to enter this pilot study. Only one patient had lymph node metastasis, which was preoperatively detected by FDG-PET scan. Additionally, another patient was considered to have lymph node metastasis according to increased focal FDG uptake; however, all lymph nodes were free of malignant disease upon final pathology. In contrast, all other patients without lymph node metastasis upon final pathology showed negative preoperative FDG-PET scans. The meta-analysis yielded a sensitivity, specificity, PPV, NPV and accuracy of 0.53, 0.91, 0.57, 0.90 and 0.84, respectively., Conclusion: In patients with uterine corpus cancer, FDG-PET had an insufficient positive predictive value in detecting lymph node metastases, indicating that this method cannot replace surgical staging. However, due to its high NPV, FDG-PET might be beneficial in selected patients who are poor candidates for surgical staging.

- Abstract
Objective: To determine whether the prescribing practice of physicians with regard to estrogen replacement therapy (ERT) in symptomatic women with previous endometrial cancer is consistent with the available evidence., Methods: A descriptive survey was conducted among physicians in Germany, using a questionnaire containing two hypothetical cases of endometrial cancer patients ('low-risk' and 'high-risk' disease) and menopausal symptoms. Physicians were asked about their prescribing practice concerning moderate to severe menopausal symptoms., Results: Four hundred and twenty questionnaires were sent out, with an overall response rate of 39.8%; 45.6% in the 'low-risk' case and 75.4% in the 'high-risk' case (p < 0.0001) stated that ERT is contraindicated. Only 12.9% were willing to prescribe ERT; 81.9% preferred to prescribe non-estrogenic alternatives (44.8% phytoestrogens, 29.0% selective serotonin reuptake inhibitors)., Conclusion: Despite the evidence that ERT does not increase the risk of recurrence of endometrial cancer, many physicians are reluctant to prescribe ERT in women suffering from moderate to severe menopausal symptoms.

- Abstract
Background: YT521 is a splicing factor involved in alternative splicing regulation of several tumor biological important genes. Two messenger RNA (mRNA) isoforms due to YT521 exon6 alternative splicing exist, with so far unknown functional consequences. Further evidence exists for a direct influence of YT521 expression in tumorigenesis because its mRNA level is changed in tumors compared with physiological tissue. We investigated the potential impact of YT521 expression on tumor biological parameters in endometrial cancer (EC)., Methods: Real-time reverse transcription-polymerase chain reaction specifically detecting YT521 exon6-retention and exon6-skipping mRNA isoforms and immunohistochemistry were performed in a cohort of 130 EC tissue samples., Results: Whereas YT521 exon6-retention mRNA was detectable in 86 (66.2%), the exon6-skipping isoform mRNA was expressed in only 8 (6.2%) of all EC samples. On the protein level, 104 (80%) of EC samples showed nuclear expression. The mRNA levels of exon6-skipping isoform were not correlated to any of the clinicopathological parameters of EC. In contrast, YT521 exon6-retention mRNA expression was positively correlated to metastasis (R = 0.196, P = 0.026) and inversely correlated to the protein expression levels (R = -0.205, P = 0.019). In univariate analyses, higher levels of YT521 exon6-retention mRNA were correlated to a poorer progression-free survival (P = 0.003), and this is confirmed by multivariate analyses (P = 0.019). The negative YT521 protein expression was correlated to poorer overall and disease-specific survival (P = 0.036 and P = 0.034), respectively, in univariate analyses. They are also confirmed by multivariate analyses (P = 0.021 and P = 0.010, respectively)., Conclusions: We characterized for the first time in a clinical setting a new but rare exon6-skipping mRNA splicing isoform of YT521. Furthermore, we identified YT521 as a potential new independent prognostic factor for patients with EC: the lack of YT521 protein in tumor cells was highly predictive for a poor overall and disease-specific survival and independent from the histological subtypes.

- Abstract
Background: The aim of this study was to investigate the prognostic effect of tumour-infiltrating lymphocytes (TILs) in serous stage III ovarian carcinoma to determine TIL clonality and to correlate this to Her2/neu expression., Methods: Formalin-fixed and paraffin-embedded ovarian carcinomas were examined for CD20-, CD3-, CD4- and CD8-positive lymphocytes (n=100), and for Her2/neu-positive tumour cells (n=55/100) by immunohistochemistry. Clonality analysis was carried out by T-cell receptor gamma (TCRgamma) gene rearrangements (n=93/100). Statistical analyses included experimental and clinico-pathological variables, as well as disease-free (DFS) and overall (OS) survival., Results: CD20-positive B lymphocytes were present in 57.7% (stromal)/33.0% (intraepithelial) and CD3-positive T lymphocytes in 99.0% (stromal)/90.2% (intraepithelial) of ovarian carcinomas. Intraepithelial CD3-positive T lymphocytes were correlated with improved DFS in optimally debulked patients (P=0.0402). Intraepithelial CD8-positive T lymphocytes were correlated with improved OS in all optimally debulked patients (P=0.0201) and in those undergoing paclitaxel/carboplatin therapy (P=0.0092). Finally, rarified and clonal TCRgamma gene rearrangements were detected in 37 out of 93 (39.8%) and 15 out of 93 (16.1%) cases, respectively. This was marginally associated with improved DFS (P=0.0873). Despite a significant correlation of HER2/neu status and intraepithelial CD8-positive lymphocytes (P=0.0264), this was non-directional (R=-0.257; P=0.0626)., Conclusion: Improved survival of ovarian cancer patients is related to the infiltration, clonal selection and intraepithelial persistence of T lymphocytes.

- Abstract
The combination therapy of doxorubicin and trastuzumab has been proven to be highly effective for metastatic breast cancer (MBC) patients with Her2/neu over-expressing tumors. However, this regimen is characterized by frequent cardiac toxicity, occurring in 27% of all treated patients and aggravating when the two substances are given concurrently. Pegylated liposomal doxorubicin (PLD) as a single agent reduces significantly cardiac toxicity and maintains efficacy compared to conventional doxorubicin. This prospective open labeled, multicenter phase II study assessed the potential cardiotoxicity and efficacy of PLD and trastuzumab as first and second line combination therapy in Her2/neu over-expressing MBC patients. Patients with Her2 over-expressing, measurable MBC with a baseline left ventricular ejection fraction (LVEF) > or =50% were treated with PLD 40 mg/m(2) every 4 weeks for 6 up to 9 cycles and weekly trastuzumab (4 mg/kg loading dose, then 2 mg/kg). Cardiotoxicity was defined as the appearance of clinical signs or symptoms of congestive heart failure in combination with a decrease in LVEF < or =44% or > or =10 units below the normal value of 50% in the obligatory, subsequently performed transthoracic echocardiography. Due to conflicting interests, the planned accrual goal of 30 patients was not reached. Finally 16 patients were enrolled. Ten patients presented with more than one metastatic site and six of them were in second-line therapy. The median LVEF in the study cohort was 66.1 +/- 8.68% at baseline, 62.7 +/- 5.11% after 6 cycles of therapy, 64.4 +/- 7.61% at the first follow up and did not change significantly (61.0 +/- 5.56% even at the 5th follow-up). Six out of 12 assessable patients (50.0%) demonstrated a clinical benefit and after a median follow-up of 15.4 months a median progression free survival of 9.67 and a median overall survival of 16.23 months. Non-cardiac side effects were mild with only 3 CTC grade 3 events of 247 treatment cycles (1.2%) and no grade 4 toxicities. The combination of PLD and trastuzumab in patients with Her2/neu over-expressing metastatic breast cancer is a safe, feasible and effective therapy. However, cardiac function should be monitored at close intervals. Due to the promising clinical response rates and mild toxicity profile in this prognostically unfavorable group, this combination therapy should be evaluated in larger studies.

- Abstract
Background: The sentinel lymph node (SLN) procedure could be omitted in cases of accurate prediction of very high or very low probability of SLN metastasis in early breast cancer patients. We evaluated a breast cancer nomogram, an online tool provided by the Memorial Sloan-Kettering Cancer Center (MSKCC), that predicts the likelihood of a positive lymph node., Methods: Data from 545 patients with successful SLN biopsy were collected, including 118 patients with a positive sentinel lymph node. Histopathological assessment of the SLN included hematoxylin and eosin staining and/or immunohistochemistry. Predictive accuracy was assessed by calculating the area under the receiver-operator characteristic (ROC) curve., Results: In our collective tumor size, histology, lymphovascular infiltration, multifocality, Her-2-neu positivity, and nuclear grade correlated with the probability of SLN metastasis. The ROC of the validated nomogram in our breast cancer population revealed a value of 0.78 compared with 0.75 in the original publication., Conclusion: The MSKCC nomogram is a useful tool in our population of breast cancer patients. However, variations in the pathological assessment of the SLN between breast cancer centers worldwide might be an impediment to widespread application of the nomogram.

- Abstract
Background: Societies worldwide invest considerably in research on oncological diseases of women. However, current literature lacks estimating this research production. We therefore evaluated quality and quantity of publications in gynecologic oncology., Methods: Revisit of 6119 peer-reviewed articles published in Gynecologic Oncology and the International Journal of Gynecological Cancer from January 1996 to December 2006. Descriptive data on disease origin, main topic, and country of origin were collected and analyzed separately. Research productivity was adjusted to the national population and nominal gross domestic product per capita., Results: Research production and international cooperative teamwork in the 2 main journals of gynecologic oncology increased within the 10 last years; 65.3% of all published articles dealt either with epithelial ovarian cancer, cervical cancer, or endometrial cancer. Endometrial cancer had the worst ratio number of publications to estimated national incidence (United States, 2007). The United States (41.15%) and Europe (29.72%) make up a striking 70.87% of the world's research production in the field of gynecologic oncology. However, the highest rate of increase shows in Turkey (22.5), the People's Republic of China (6.87), and South Korea (5.83). Adjusted to the national GDP per capita and population for the year 2006, research productivity seems best in Israel, Austria, and Turkey., Conclusion: Quantitatively, most publications come from the presumed countries. Within the limits of the methodology used in this study, adjustment to population and GDP per capita provides information on research output. The scientific output on endometrial cancer is comparably low.
