Obesity and survival among women with ovarian cancer: results from the Ovarian Cancer Association ConsortiumBACKGROUND: Observational studies have reported a modest association between obesity and risk of ovarian cancer; however, whether it is also associated with survival and whether this association varies for the different histologic subtypes are not clear. We undertook an international collaborative analysis to assess the association between body mass index (BMI), assessed shortly before diagnosis, progression-free survival (PFS), ovarian cancer-specific survival and overall survival (OS) among women with invasive ovarian cancer. METHODS: We used original data from 21 studies, which included 12 390 women with ovarian carcinoma. We combined study-specific adjusted hazard ratios (HRs) using random-effects models to estimate pooled HRs (pHR). We further explored associations by histologic subtype. RESULTS: Overall, 6715 (54%) deaths occurred during follow-up. A significant OS disadvantage was observed for women who were obese (BMI: 30-34.9, pHR: 1.10 (95% confidence intervals (CIs): 0.99-1.23); BMI: ⩾35, pHR: 1.12 (95% CI: 1.01-1.25)). Results were similar for PFS and ovarian cancer-specific survival. In analyses stratified by histologic subtype, associations were strongest for women with low-grade serous (pHR: 1.12 per 5 kg m(-2)) and endometrioid subtypes (pHR: 1.08 per 5 kg m(-2)), and more modest for the high-grade serous (pHR: 1.04 per 5 kg m(-2)) subtype, but only the association with high-grade serous cancers was significant. CONCLUSIONS: Higher BMI is associated with adverse survival among the majority of women with ovarian cancer.
Single deepest vertical pocket or amniotic fluid index as evaluation test for predicting adverse pregnancy outcome (SAFE trial): a multicenter, open‐label, randomized controlled trialSven Kehl, A. Schelkle, A. Thomas et al.|Ultrasound in Obstetrics and Gynecology|2015 OBJECTIVE: To determine whether the amniotic fluid index (AFI) or the single deepest vertical pocket (SDP) technique for estimating amniotic fluid volume is superior for predicting adverse pregnancy outcome. METHODS: This was a multicenter randomized controlled trial including 1052 pregnant women with a term singleton pregnancy across four hospitals in Germany. Women were assigned randomly, according to a computer-generated allocation sequence, to AFI or SDP measurement for estimation of amniotic fluid volume. Oligohydramnios was defined as AFI ≤ 5 cm or the absence of a pocket measuring at least 2 × 1 cm. The diagnosis of oligohydramnios was followed by labor induction. The primary outcome measure was postpartum admission to a neonatal intensive care unit. Further outcome parameters were the rates of diagnosis of oligohydramnios and induction of labor (for oligohydramnios or without specific indication), and mode of delivery. RESULTS: Postpartum admission to a neonatal intensive care unit was similar between groups (4.2% (n = 21) vs 5.0% (n = 25); relative risk (RR), 0.85 (95% CI, 0.48-1.50); P = 0.57). In the AFI group, there were more cases of oligohydramnios (9.8% (n = 49) vs 2.2% (n = 11); RR, 4.51 (95% CI, 2.2-8.57); P < 0.01) and more cases of labor induction for oligohydramnios (12.7% (n = 33) vs 3.6% (n = 10); RR, 3.50 (95% CI, 1.76-6.96); P < 0.01) than in the SDP group. Moreover, an abnormal cardiotocography was seen more often in the AFI group than in the SDP group (32.3% (n = 161) vs 26.2% (n = 132); RR, 1.23 (95% CI, 1.02-1.50); P = 0.03). The other outcome measures were not significantly different between the two groups. CONCLUSIONS: Use of the AFI method increased the rate of diagnosis of oligohydramnios and labor induction for oligohydramnios without improving perinatal outcome. The SDP method is therefore the favorable method to estimate amniotic fluid volume, especially in a population with many low-risk pregnancies. Copyright © 2015 ISUOG.

Insights into the molecular biology of the estrogen receptor define novel therapeutic targets for breast cancerBettina Hanstein, S. Djahansouzi, Peter Dall et al.|European Journal of Endocrinology|2004 Evidence for a role of ovarian factors in the growth of metastatic breast cancer was first recognized over 100 years ago. Today, anti-estrogens are central to the treatment of breast cancer of all stages. We now understand that the action of estrogen is mediated by the estrogen receptors (ER) which are members of the nuclear receptor family of ligand-regulated transcription factors. In this article we review the molecular mechanisms through which ER activates transcription of target genes and through which available anti-estrogens mediate their therapeutic effects. We discuss possible mechanisms of failure of treatment with current anti-estrogens and how newer anti-estrogens under development attempt to address these problems. In addition an expanded view of the molecular mechanisms of estrogen action is leading to the development of novel selective ER modulators or SERMs.
Angiogenic growth factor levels in maternal and fetal blood: correlation with Doppler ultrasound parameters in pregnancies complicated by pre‐eclampsia and intrauterine growth restrictionDietmar Schlembach, W. Wallner, Ruth Sengenberger et al.|Ultrasound in Obstetrics and Gynecology|2007 OBJECTIVES: To correlate levels of angiogenic growth factors with Doppler ultrasound parameters in pregnancies complicated by pre-eclampsia and intrauterine growth restriction (IUGR). METHODS: In 16 women with pre-eclampsia and 15 women with isolated IUGR, pulsatility indices (PI) in the umbilical and uterine arteries were measured by Doppler ultrasonography. At delivery, maternal and fetal blood (umbilical vein and artery separately) was sampled and angiogenic growth factors measured by means of enzyme linked immunosorbent assay (ELISA). RESULTS: Umbilical artery PI was significantly higher in women with IUGR than in those with pre-eclampsia, whereas uterine artery PI was not statistically significantly different. Maternal soluble fms-like tyrosine kinase-1 (sFlt-1) levels were higher in women with pre-eclampsia than in those with IUGR (P < 0.0001). Umbilical vein basic fibroblast growth factor (bFGF) levels were lower in women with pre-eclampsia than in those with IUGR (P < 0.05). Placental growth factor (PlGF) levels in the umbilical vein were below the detection limit in nearly all samples of IUGR fetuses and lower than in those with pre-eclampsia (P < 0.001). Maternal PlGF levels were inversely correlated with PI values of both vessels. In the umbilical vein sFlt-1 was positively and soluble kinase insert domain receptor (sKDR) negatively correlated with umbilical artery PI. No correlation could be found in the serum of the umbilical artery for all growth factors and for vascular endothelial growth factor (VEGF) in all compartments. CONCLUSIONS: The correlations between maternal and fetal angiogenic growth factor serum levels and Doppler ultrasound indices of uterine and umbilical arteries in pre-eclampsia and IUGR reflect the severity of the disorders especially for the fetus. A combination of both measurements may be useful in future screening for early prediction of pregnancy complications. Published by John Wiley & Sons, Ltd.
Use of circulating tumor cells (CTC) in peripheral blood of breast cancer patients before and after adjuvant chemotherapy to predict risk for relapse: The SUCCESS trial.1003 Background: The prognostic significance of CTCs in MBC has been demonstrated. We evaluated whether the presence of CTC before and after adjuvant chemotherapy increases the risk of subsequent relapse and death. Methods: We analyzed 23 mL of peripheral blood from 1,489 N+ and high risk N- breast cancer pts before and after adjuvant taxane based chemotherapy. CTC were assessed with the CellSearchSystem (Veridex, USA). After immunomagnetic enrichment with an anti-Epcam-antibody, cells were labelled with anti-Ck8/18/19 and anti-CD45 antibodies to distinguish between epithelial cells and leukocytes. Pts were followed for a median of 32 months. Results: In 9.4% of pts (n > 140) > 1 CTC was detected before the start of systemic treatment (median 1, range 1-827), while 8.7% (n > 129) presented with > 1 CTC (median 1, range 1-124) after chemotherapy. Pts with CTC before treatment had significantly more lymphnodes involved (p < 0.01), but no correlation to tumor size, grading and HR-Status could be found. 85 recurrences occurred and 33 pts died of their disease. The presence of > 1 CTC before treatment was a significant prognostic factor with respect to poor DFS (p < 0.0001) and OAS (p > 0.023), whereas the persistence of > 1 CTC after chemotherapy only predicted reduced DFS (p > 0.054; p > 0.154 for OAS). A significantly better DFS and OAS was detected between the groups with persistently negative CTC status compared to those with persistently positive CTC status (p > 0.0031 and p > 0.0187). More than 5 CTC were a significant indicator of poor prognosis for DFS and OAS at all time points. In multivariate analysis, > 1CTC before treatment was an independent predictor for OAS, > 1 CTC after treatment for DFS, while tumor size, lymph node involvement, grading and HR-status were relevant for both time points. Conclusions: We demonstrated the prognostic relevance of CTC in peripheral blood of early breast cancer pts before and after chemotherapy. Therefore, CTC detection could serve as clinically useful prognostic marker and treatment monitoring tool and should be tested as indicator for additional secondary adjuvant treatment intervention within clinical trials.
