Abstract
OBJECTIVE To test the ability of a group of serum cytokines, either individually or in combination, to serve as biomarkers for the nonsurgical diagnosis of endometriosis. STUDY DESIGN Subjects were allocated to two groups according to their laparoscopic diagnosis. The first group consisted of patients with endometriosis and the second group was made up of infertile women with no pelvic pathology (controls). Blood samples were collected preoperatively and stored. Cytokines were measured in the serum of all participants using the Bio-Plex Protein Array System. Nonparametric statistics and the Mann-Whitney test were used to compare groups. Subjects were seen at the Gynecologic endoscopy unit. RESULTS Three cytokines were significantly higher in the serum of subjects with endometriosis than in the control group: interleukin-6 (IL-6) [4.41 pg/ml (range: 1.47-15.01) versus 0.97 pg/ml (range: 0.29-2.98), respectively; p<0.001], monocyte chemotactic protein-1 (MCP-1) [37.91 pg/ml (range: 24.54-94.74) versus 22.13 pg/ml (range: 13.85-39.45), respectively; p<0.001], and interferon-gamma (INF-gamma) [19.01 pg/ml (range: 1.19-73.52) versus 0.30 pg/ml (range: 0.00-13.05), respectively; p<0.001]. There was no statistically significant difference between subjects with endometriosis and controls in the serum concentration of vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-alpha), or granulocyte macrophage colony stimulating factor (GM-CSF). Interleukin-2 (IL-2), interleukin-8 (IL-8), and interleukin-15 (IL-15) were undetectable in the serum of both groups. None of the measured cytokines showed significant correlation with the cycle phase or stage of endometriosis. In a multivariate analysis, serum interleukin-6 provided a sensitivity of 71% and a specificity of 66% to discriminate between endometriosis patients and controls at a cutoff point of 1.9 pg/ml. Adding monocyte chemotactic protein-1 and interferon-gamma to interleukin-6 did not increase the discriminative ability over that achieved by measuring serum interleukin-6 alone. CONCLUSIONS Serum of subjects with endometriosis contains significantly higher levels of interleukin-6, monocyte chemotactic protein-1, and interferon-gamma than control women. Serum interleukin-6 measurements discriminate between women with endometriosis and controls. Interleukin-6 provides a promising serum marker for the nonsurgical prediction of endometriosis.

Abstract
PURPOSE The objective of the study was to determine the feasibility of a new method of labeling sentinel lymph nodes in patients with endometrial cancer using blue dye. PATIENTS AND METHODS 4 ml of blue dye was subserously administered in 25 patients with endometrial cancer at eight sites. After 8 min, sentinel lymph nodes were harvested. RESULTS Detection rate was 92.0%, sensitivity was 62.5%, and negative predictive value was 92.5%. In two patients there was no detection of sentinel nodes and in addition in two patients only sentinel nodes were harvested due to minimal disease. No side effects occurred. CONCLUSIONS This new and simple approach yielded a high pelvic detection rate. This new approach reveals a way to label sentinel nodes in endometrial cancer. Combining a different labeling agent with the proposed new method might overcome the lack of para-aortic sentinel detection.

Abstract
We investigated the expression of the cognate chemokine receptor 1 (CCR1) messenger ribonucleic acid, a G-protein-coupled cognate chemokine receptor with high affinity for RANTES (Regulated upon Activation, Normal T cells Expressed and Secreted), in peripheral blood leukocytes of women with and without endometriosis, and its potential use as a diagnostic test for endometriosis. Because patients with an earlier diagnosis of this disease have a better treatment outcome and a reduced recurrence rate, CCR1 mRNA measurement in the peripheral blood of patients with suspected endometriosis might give us a new perspective in diagnosing and treating this disease earlier and better.

Abstract
Monocyte chemotactic protein-1 (MCP-1) is an important determinant of macrophage infiltration in tumours. This study investigated the effect of tamoxifen and the gonadotrophin-releasing hormone agonist buserelin on MCP-1 in the human endometrial cancer cell line EFE-184. Reverse transcription polymerase chain reaction and Western blot analysis were used to determine MCP-1 mRNA and protein expression, respectively. Immunoreactive MCP-1 in the cell culture media was quantified by enzyme-linked immunosorbent assay. Tamoxifen inhibited MCP-1 mRNA and protein expression in endometrial cancer cells and inhibited MCP-1 secretion in a time- and dose-dependent manner at concentrations of 10(-7) to 10(-5) M. Buserelin had no significant effect on MCP-1 mRNA and protein expression. These results suggest that tamoxifen directly inhibits the expression of MCP-1 in this cell line by blocking the MCP-1 signalling pathways. These findings may contribute to the understanding of the mechanisms underlying the different effects of tamoxifen and gonadotrophin-releasing hormone agonists in the treatment of endometrial cancer.

Abstract
OBJECTIVE To compare the amount of regulated upon activation, normal T cell expressed and secreted (RANTES) and monocyte chemotactic protein 1 (MCP-1) in follicular fluid (FF) of patients with and without endometriosis and to determine their oocyte fertilization and pregnancy rates. DESIGN Case-control study. SETTING Department of Obstetrics and Gynecology, University Hospital Schleswig-Holstein, Campus Luebeck, Germany. PATIENT(S) Thirty-two women with endometriosis stages I-IV and 28 women without endometriosis, both groups surgically and histologically confirmed. INTERVENTION(S) Diagnostic laparoscopy, IVF-ET. MAIN OUTCOME MEASURE(S) RANTES and MCP-1 levels in follicular fluid, measured by ELISA, and oocyte fertilization and pregnancy rates. RESULT(S) Follicular response and days of gonadotropin stimulation were similar between the two groups. The levels of RANTES in FF from patients with endometriosis were significantly higher (460.4 +/- 90.3 pg/mL) compared with concentrations in patients with tubal infertility (243.8 +/- 70.9 pg/mL; P<.05). In contrast, MCP-1 concentrations in FF from women with endometriosis (330.0 +/- 29.2 pg/mL) were lower than in women with tubal infertility (420.5 +/- 46.6 pg/mL; P<.05). Oocyte fertilization rates in the endometriosis group (54%) were significantly lower than those of the tubal infertility group (73%; P<.05), as were the pregnancy rates (19% vs. 35%, respectively; P<.01). CONCLUSION(S) Women with endometriosis-associated infertility have a poor IVF outcome. Immune cell recruitment into the ovary might affect follicular function and lead to impaired oocyte quality.

Abstract
The use of cetrorelix within ovarian-stimulation protocols demonstrates several advantages compared with gonadotropin-releasing hormone (GnRH) agonist-containing protocols, which include, for example, significantly less time for analogue treatment and a reduction in the amount of gonadotropins needed. Furthermore, fewer side effects can be expected. There is no difference regarding endometrium quality and hormone profiles, and the results of assisted reproduction cycles are comparable. Cetrorelix also seems to be useful in the treatment of endometriosis which, in most cases, is an estrogen-dependent disease. Furthermore, fewer side effects occur with this agent (e.g., postmenopausal symptoms) and no estradiol add-back is needed. In the future, new nonpeptic GnRH antagonists are expected to be available for oral administration. Although they are still under investigation, these agents have the potential to improve patients' comfort and compliance.

Abstract
Endometriosis is a pelvic inflammatory process with altered function of immune-related cells and increased number of activated macrophages in the peritoneal environment that secrete various local products, such as growth factors and cytokines. The elevation of cytokines and other factors in the peritoneal fluid is accompanied by the elevation of similar factors, such as CRP, SAA, TNF-alpha, MCP-1, IL-6, IL-8 and CCR1, in the peripheral blood of patients with endometriosis. CD44+ and CD14+ monocytes are significantly increased, while CD3+ T lymphocytes and CD20+ B lymphocytes show modest, but significant decrease in peripheral blood of women with endometriosis. This indicates that endometriosis could be viewed as a local disease with systemic subclinical manifestations. This review provides an overview of data on the changes of various factors in peripheral blood and their potential use as diagnostic tools in patients with endometriosis.

Abstract
Xanthogranulomatous inflammation is rare, mainly involving the kidneys, while primary xanthogranulomatous endometritis (XE) is a very unusual finding, histologically characterized by partial or complete replacement of the mucosa by granulation tissue with an abundance of foamy histiocytes, siderophages and multinucleated giant cells. We present the case of a 69-year-old woman with a short history of abdominal pain and a palpable mass in the pouch of Douglas. Dilatation of the cervix drained a pyometra. Histological examination of the curettage rendered the diagnosis of XE. Microbiological studies revealed enterococcus spp. and Peptostreptococcus magnus. Despite antibiotic treatment the patient died of heart failure due to systemic inflammation. Autopsy confirmed the diagnosis of XE with transmural extension into the peritoneal cavity. Such a lethal course of XE is extraordinary. Proposed causes of XE include obstruction, infection and hemorrhage. Demonstration of enterococcus spp. and P. magnus supports the probable significance of bacteria in the development of XE. Because this condition may mimic malignant disease macroscopically and histologically, knowledge of XE is of major importance for both pathologists and gynecologists.

Abstract
Endogenous retroviruses (ERVs) probably originate from ancient germ cell infections by exogenous retroviruses. A high expression of retroviruses in reproductive tissue increases the risk of viral transmission to germ line cells. We therefore investigated the expression of human ERVs (HERVs) in normal endometrium, endometriosis, normal ovaries, and ovarian cancer. Four real-time PCRs (QPCRs) for HERV-E, HERV-I/T, HERV-H, and HERV-W, respectively, and an expression control gene were used. HERV-E RNA expression was significantly higher in endometriotic tissue (average, SD) than in normal endometrium (average, SD), both measured as ratios versus control gene expression and as. HERV-E and HERV-W RNA were higher in normal ovarian tissue than in ovarian cancer. This illustrates that HERV expression is not automatically higher in malignant tissues. The other HERV PCRs did not show expression patterns as distinctive as HERVE and HERV-W in the two kinds of reproductive tissue. A small number of candidate HERV-E loci from which the transcription took place were identified by sequencing of amplimers. The role of HERV-E and HERV-W in endometriosis merits further investigation.

Abstract
CONTEXT The nuclear factor-kappaB (NF-kappaB) pathway is a critical mediator of RANTES (regulated on activation, normal T cell expressed and secreted) gene regulation and therefore represents a potential target for therapy of endometriosis-associated symptoms. OBJECTIVE The objective of this study was to investigate the effects of the antiinflammatory drug sulindac on NF-kappaB activation, NF-kappaB-mediated gene expression, RANTES gene and protein expression in endometrial stromal cells isolated from women with endometriosis, and unaffected controls. DESIGN This was a clinical experimental study. SETTING The study was conducted at a university hospital. RESULTS The inflammatory response in endometriosis is augmented by a 5-fold increased TNFalpha-induced RANTES secretion from ectopic endometriotic stromal cells, compared with normal endometrial stromal cells (P < 0.05). Western blot analysis revealed basal activation of NF-kappaB in endometriotic cells, which could be suppressed by sulindac. EMSAs showed that sulindac dramatically decreased NF-kappaB activation and diminished TNFalpha and IL-1beta-induced NF-kappaB DNA binding activity. Sulindac pretreatment resulted in a significant decrease in TNFalpha-induced luciferase activity of NF-kappaB response element and -477 bp RANTES promoter constructs in normal and endometriotic stromal cells. The addition of sulindac to IL-1beta- and TNFalpha-treated endometriotic stromal cells also resulted in a 4-fold inhibition of RANTES protein secretion (P < 0.05). CONCLUSIONS We have demonstrated that sulindac exerts strong antiinflammatory effects by suppression of NF-kappaB translocation, inhibition of NF-kappaB-mediated gene transcription, RANTES gene expression, and protein secretion in normal and endometriotic stromal cells. These results suggest that drugs targeting the NF-kappaB pathway may be beneficial in the treatment of endometriosis-associated symptoms.

Abstract
Gonadotropin-releasing hormone (GnRH) stimulates the pituitary secretion of both luteinising hormone (LH) and follicle-stimulating hormone (FSH), and thus controls the hormonal and reproductive functions of the gonads. The blockade of the effects of GnRH may be sought for a variety of reasons; for example, to control premature LH surges and to reduce the cancellation rate with the aim of improving the pregnancy rate per treatment cycle or in the treatment of sex hormone-dependent disorders. Selective blockade of LH/FSH secretion and subsequent chemical castration have previously been achieved by desensitising the pituitary to continuously administered GnRH or by giving long-acting GnRH agonists. GnRH analogues are indicated for clinical situations in which the suppression of endogenous gonadotropins (precocious puberty, contraception and controlled ovarian hyperstimulation) or sexual steroids (endometriosis, prostate hyperplasia, cancer and uterine fibroids) is desired. The immediate suppression of the pituitary that is achieved by GnRH antagonists without an initial stimulatory effect is the main advantage of these compounds over the agonists. GnRH antagonists have been developed for clinical use with acceptable pharmacokinetic, safety and commercial profiles. In assisted reproduction, these compounds seem to be as effective as established therapy, but with shorter treatment times, less use of gonadotropic hormones, improved patient acceptance, and fewer follicles and oocytes. All of the current indications for GnRH agonist desensitisation may prove to be indications for a GnRH antagonist, including endometriosis, leiomyoma and breast cancer in women, benign prostatic hypertrophy and prostatic carcinoma in men, and central precocious puberty in children. However, the best clinical evidence has been in assisted reproduction and prostate cancer.

Abstract
Usually, the therapy of metastatic breast cancer consists of chemotherapy or endocrine therapy, because even in the case of isolated metastases in one organ, diffuse tumor cell dissemination exists, so that local surgical treatment does not seem sensible. Particurlarly in patients with hepatic or pulmonary metastases the indication for hepatic or pulmonary metastasectomy should be individualized, as hepatic or pulmonary metastases usually develop during a phase of disease, when extrahepatic or -pulmonary metastases also can be detected. Only in patients with long disease-free interval, with isolated hepatic or pulmonary metastases, and the possibility of R0-resection is hepatic or pulmonary metastasectomy a therapeutic option in selected cases.

Abstract
BACKGROUND Suppression of endogenous LH production by mid-follicular phase GnRH-antagonist administration in controlled ovarian hyperstimulation protocol using recombinant (rec) FSH preparations void of LH activity may potentially affect ovarian response and the outcome of IVF treatment. The present study prospectively assessed the effect of using a combination of recFSH and recLH on ovarian stimulation parameters and treatment outcome in a fixed GnRH-antagonist multiple dose protocol. METHODS 127 infertile patients with an indication for IVF or ICSI were recruited and randomized (using sealed envelopes) to receive a starting dose of either 150 IU recFSH (follitropin alpha) or 150 IU recFSH plus 75 IU recLH (lutropin alpha) for ovarian hyperstimulation. GnRH-antagonist (Cetrorelix) 0.25 mg was administered daily from stimulation day 6 onwards up to and including the day of the administration of recombinant HCG (chorion gonadotropin alpha). Gonadotropin dose adjustments were allowed from stimulation day 6 onwards, HCG was administered as soon as three follicles > or =18 mm were present. The primary outcome parameter was treatment duration until administration of HCG. RESULTS Exogenous LH did not shorten the time necessary to reach ovulation induction criteria. Serum estradiol (E(2)) and LH levels were significantly higher on the day of HCG administration in the recLH-supplemented group (1924.7 +/- 1256.4 vs 1488.3 +/- 824.0 pg/ml, P < 0.03), and 2.1 +/- 1.4 vs 1.4 +/- 1.5 IU/l, P < 0.01, respectively). CONCLUSIONS Except for higher E(2) and LH levels on the day of HCG administration, no positive trend in favour of additional LH was found as defined by treatment outcome parameters.
