Abstract
OBJECTIVE Two-dimensional (2D) transvaginal ultrasound (TVS) is an accessible and cost-effective diagnostic tool for the detection of adenomyosis. Different ultrasound features related to adenomyosis have been described, but the predictive value of each ultrasound sign and their combinations requires further investigation. We aimed to analyze the accuracy of 2D-TVS and describe possible combinations of ultrasound signs with a high predictive value in the diagnosis of adenomyosis. METHODS This was a prospective multicenter study of patients scheduled for laparoscopic hysterectomy who had been examined using standardized 2D-TVS at nine expert centers specializing in the diagnosis and treatment of endometriosis. 2D-TVS examination included nine typical adenomyosis ultrasound features, comprising heterogeneous myometrium, myometrial linear striations, myometrial cysts, subendometrial microcysts, asymmetrical myometrial thickening, uterine enlargement, the 'question mark sign', thickening of the junctional zone and hyperechoic myometrial spots, in order to predict or exclude the presence of adenomyosis. Ultrasound examination results were compared with histology after hysterectomy. The diagnostic reliability of the nine ultrasound signs and their combinations, and the influence of concurrent fibroids on the accuracy of the results, were analyzed. RESULTS A total of 202 patients were enrolled into the study. Histopathological examination revealed adenomyosis in 130 patients (64.4%). The accuracy of prediction of adenomyosis by 2D-TVS examination using all signs was 63.4% (positive predictive value, 71.5%; negative predictive value, 48.6%; sensitivity, 71.5%; specificity, 48.6%). Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy (55.7-62.1%) as individual ultrasound signs for the prediction of adenomyosis. The combination of the most accurate ultrasound signs (subendometrial microcysts, myometrial cysts and heterogeneous myometrium) improved the specificity of prediction (86.1%) when compared with that of these three single markers (35.2-81.7%). Uterine enlargement and asymmetry showed both low sensitivity (60.8% and 52.3%, respectively) and specificity (41.7% and 49.3%, respectively) as individual sonographic signs. CONCLUSIONS Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy for the detection of adenomyosis in this study, while uterine enlargement and asymmetry led to high false-positive and false-negative results. A combination of ultrasound features including the most accurate signs increases specificity. © 2023 The Authors.

Abstract
Introduction Endometriosis significantly reduces patients' quality of life and is additionally a burden on healthcare and social security systems. There are currently no quality indicators for the treatment of endometriosis. The care of patients with endometriosis must be considered inadequate. QS ENDO aims to record the quality of care available in the DACH region and to introduce quality indicators for the diagnosis and treatment of endometriosis as part of providing quality assurance in endometriosis care. The first phase, QS ENDO Real, recorded the reality of current care using a questionnaire. The second phase, QS ENDO Pilot, investigated the treatment of 435 patients who underwent surgical treatment within a defined one month period in certified endometriosis centers. Material and Methods An online tool was used to gather information about 9 points which covered both prior patient history and the process of clinical diagnosis. Surgery reports were reviewed to obtain information about the surgical approach, the investigated sites, findings of any histological examinations, the use of classification systems, and information about resection status. Results 85.3% of patients were asked all 4 questions about their prior medical history. All 5 diagnostic steps were carried out in 34.5% of patients. The 3 areas needed to describe potential sites of disease were recorded in 67.1% of patients. Samples for histological examination were taken in 84.1% of patients. The endometriosis stage was classified in 94.7% of surgeries. A combination of the rASRM and the ENZIAN classifications, which is needed for complex cases, was used in 46.1% of patients. Complete resection was achieved in 81.6% of surgical procedures. Conclusion For the first time, the quality of care in certified endometriosis centers has been recorded using QS ENDO Pilot. Despite the high certification standards, a substantial number of required indicators were omitted.

Abstract
OBJECTIVE To assess the diagnostic performance of preoperative application of the Enzian classification (cEnzian) using surgical findings as reference standard. DESIGN A prospective international non-interventional study. SETTING Twelve endometriosis centres in four European countries (Austria, Germany, Switzerland and Czech Republic). POPULATION 1062 women with endometriosis surgery. METHODS Extent of endometriosis was preoperatively classified using the cEnzian classification based on gynaecological examination and/or transvaginal ultrasound (TVS) and/or magnetic resonance imaging (MRI). After subsequent surgery, the surgeon classified the intraoperative findings using the Enzian classification. MAIN OUTCOME MEASURES Sensitivity, specificity, PPV, NPV, LR+ , LR- and accuracy were calculated. Conditional frequencies of intraoperative Enzian codings and the corresponding 95% confidence intervals were computed for each preoperative coding and visualised in plots. RESULTS Although overall consistency of cEnzian and Enzian was poor (35.14%, 95% confidence interval 32.26-38.03), high specificities and negative predictive values (NPVs) of the cEnzian compartments could be demonstrated. Looking at the individual parts of the Enzian classification, the poorest diagnostic performance was detected for compartment B and the highest PPVs were found for category 3 lesions (>3 cm), independent of the compartment. CONCLUSIONS Using the Enzian classification in a non-invasive setting is a useful tool providing us with an 'at a glance' summary of the diagnostic workup regarding deep endometriosis with high specificities and NPVs. An attempt to merge the two new endometriosis classification systems (#Enzian and AAGL 2021) seems reasonable taking into consideration the respective advantages of each other.

Abstract
Endometriosis affects a significant number of young premenopausal women. Quite apart from the medical challenges, endometriosis is a relevant burden for healthcare and social security systems. Standardized quality indicators for the treatment of endometriosis have not previously been systematically verified. The three-stage study QS ENDO was initiated to record and improve the reality and quality of care. One of its aims is to create quality indicators for the diagnosis and treatment of endometriosis. For the first stage of QS ENDO Real, letters were sent to all 1014 gynecological departments in the German-speaking area of Europe (the DACH region) which included a questionnaire as a means of surveying the current state of care. A total of 296 (29.2%) of the centers which received the questionnaire participated in the survey. The subsequent evaluation of the completed questionnaires showed that the majority of patients with endometriosis (around 60%, based on estimates from the data) are not treated in hospitals which have been certified by the SEF. The guidelines recommend the use of specific classification systems (rASRM, ENZIAN) but, depending on the level of care offered by the hospital, only around 44.4 to 66.4% of departments used the rASRM score and only 27% of hospitals used the ENZIAN classification system to describe deep-infiltrating endometriosis. When taking patientsʼ medical history, some centers (6.6 – 17.9%) considered questions about leading symptoms such as dyschezia, dysuria and dyspareunia to be unimportant. QS ENDO Real has made it possible, for the first time, to get an overview of the reality of care provided to patients with endometriosis in the German-speaking areas of Europe. The findings indicate that several of the measures recommended in international guidelines as the gold standard of care are only used to treat some of the patients. In this respect, more efforts will be needed to provide more advanced training. The approach used for treatment must be guideline-based, also in not-certified centers, to improve the quality of care in the treatment of patients with endometriosis.

Abstract
BACKGROUND The anticarcinogenic potential of vitamin D 25(OH)D has been attributed to the inhibition of proliferation of cells from different carcinomas. Reduced serum levels of 25(OH)D are associated with an increased incidence of various types of cancer. The influence of serum 25(OH)D on the incidence and outcome of patients with vulvar cancer is unknown. PATIENTS AND METHODS The serum 25(OH)D levels in 24 patients with vulvar cancer and 24 age-matched cancer-free patients was investigated. The blood samples were collected between October 2009 and September 2010 and time of blood collection of each patient and control was matched to avoid seasonal variations between the pairs. RESULTS The median 25(OH)D serum levels in the under 50 year old group of patients were significantly lower in the vulvar cancer group than the controls. The younger cancer group also had an age-related trend of lower median serum level than the older population. In the control population the trend was vice versa, yet this finding was not statistically significant. CONCLUSION Serum 25(OH)D has a possible role in the pathogenesis and progression of vulvar cancer, but further investigations of the association of vitamin D and vulvar cancer as well as regarding its influence on patient survival and quality of life are warranted in the future.

Abstract
BACKGROUND Cyclooxygenase-2 (COX-2) plays a crucial role in prognosis of malignancy and has been associated with carcinogenesis, particularly neoangiogenesis and tumor progression. 15-Hydroxyprostaglandin dehydrogenase (15-PGDH) is described as a tumour suppressor in cancer. The antiproliferative effects of calcitriol [1,25(OH)(2)D(3)] mediated via the vitamin D receptor (VDR) render vitamin D a promising target in breast cancer therapy. MATERIALS AND METHODS The expression of prostaglandin (PG)-metabolizing enzymes, vitamin D-metabolising enzymes and VDR were determined in benign and malignant breast cell lines using western blot analysis. RESULTS We detected an inverse correlation between the two types of metabolism, a reduced VDR expression in the malignant breast cell lines, and therefore an insufficient induction of 24-hydroxylase in the malignant cells. CONCLUSION We suggest the possibility of dysregulation of vitamin D-metabolizing enzymes in malignant breast cell lines.

Abstract
BACKGROUND Vitamin D and its active form calcitriol have multiple effects in cancer cells, such as anti-proliferative effects, induction of apoptosis and cell cycle arrest. There is a link between vitamin D metabolism and inflammatory processes, which should be considered in cancer therapy. An association between these two types of metabolism is also observed in breast and ovarian cancer. These inflammatory processes are based on an increase of cyclooxygenase-2 (COX-2) activity. The current study aimed to evaluate the expression of prostaglandin-metabolising enzymes COX-2 and 15-hydroxyprostaglandin-dehydrogenase (15-PGDH) along with the vitamin D receptor (VDR) in benign and malignant breast and ovarian tissues. PATIENTS AND METHODS VDR, COX-2, 15-PGDH and prostanoid receptor E2/E4 expression were measured in tissues by western blot analysis. Additionally, plasma 25(OH)(2)D(3) and PGE(2) levels were measured in healthy patients and cancer patients. RESULTS We detected an elevated COX-2 and inversely a lowered VDR expression in cancer patients compared to healthy women. Breast cancer patients diagnosed during wintertime had a significantly lower serum level of 25(OH)(2)D(3); PGE(2) serum levels were higher in both types of cancer. CONCLUSION These results support the idea of a link between prostaglandin and vitamin D metabolism in regards to their influences on breast and ovarian cancer.

Abstract
The anticarcinogenic potential of vitamin D is attributed to antiproliferative and prodifferentiative effects on cells for a wide variety of carcinomas. The biological effects of 1,25(OH)(2)D (calcitriol) are mediated through a soluble receptor protein termed vitamin D receptor (VDR). However, thus far there have been no studies evaluating the association between VDR expression and vulvar cancer. Using immunohistochemical analysis, VDR expression was evaluated separately in the nucleus, cytoplasm and membrane, in vulvar cancer samples and adjacent non-pathological vulvar tissue from 48 squamous cell carcinoma patients with no prior therapy, and the association between VDR and overall survival was investigated. Overall, among the 48 vulvar cancer cases, nuclear and cytoplasmic VDR expression was present in 47 (97.9%) and 23 (47.9%) cases respectively. The median nuclear VDR expression was significantly higher as compared to the cytoplasmic VDR in the vulvar cancer tissue. No significant correlation between VDR values and the age of the patients was detected. Nuclear and cytoplasmatic VDR in the vulvar cancer tissue were also compared according to the tumor size, and no significant association between mean tumor VDR and tumor size was detected. There was no association between cytoplasmatic VDR expression and OS, but better OS was observed in patients with reduced nuclear VDR expression as compared to those with high VDR expression. VDR may be considered as a useful pathological marker.

Abstract
BACKGROUND Cyclooxygenase-2 (COX-2) is a potential molecular prognostic factor for breast cancer, and calcitriol [1,25(OH)(2)D(3)], the biologically active form of vitamin D, is a promising target in breast cancer therapy. MATERIALS AND METHODS The influence of calcitriol on the proliferation and the effects of calcitriol on the expression of prostaglandin- and vitamin D-metabolising enzymes were examined in benign and malignant breast cells. RESULTS Calcitriol inhibited the proliferation of MCF-10F and MCF-7 cells but not of invasive MDA-MB-231 cells and reduced the expression of COX-2 and 15-hydroxyprostaglandin dehydrogenase (15-PGDH) in the benign breast cell line MCF-10F. Furthermore, dysregulation in vitamin D-metabolising proteins was detected, especially in MDA-MB-231 cells. CONCLUSION These results suggest dysregulation of vitamin D metabolism and a lack of a possible influence of calcitriol on the metabolism of prostaglandins in the malignant breast cell lines.

Abstract
Malignant tumors of the vulva soft tissue are uncommon. About 1-3% are sarcomas. They can be mistaken as benign lesions, leading to misdiagnosis and mistreatment. A case of a 71-year-old woman with a leiomyosarcoma of the vulva is presented. The surgical excision of the lesion is described and there were no additional malignancies or lesions found. There was no need for adjuvant therapy.

Abstract
UNLABELLED In gynecologic oncology lymphadenectomy is of prognostic and therapeutic importance because recurrence-free time and survival depend on the metastatic involvement of lymph nodes. Lymphadenectomies are not performed to such an extent as they are indicated. This might be due to a laborious or problematic preparation. The authors therefore report their experience in a seldom taught preparation of the left para-aortic compartment in the form of a learning curve. MATERIALS AND METHODS To access the left para-aortic area, the descending colon is lifted to open the retroperitoneum along the line of Toldt. The mesentery of the descending colon was separated from the kidney along the fascia of Gerota by blunt preparation. Time was measured from the incision of the peritoneum until the renal vein was clearly visible. RESULTS The authors collected the data from the first 25 preparations. Mean duration for the left para-aortic preparation was 7.8 minutes compared to 5.9 minutes for the right side. Duration of preparation of the left area dropped from 11.0 minutes within the first patients (#1 to #5) to 3.8 minutes in the last patients (#20 to #25). No complications were observed in the study group linked to the retromesenteric approach described. CONCLUSION Retromesenteric para-aortic lymphadenectomy is quick to learn. The authors needed 20 preparations to observe a significant drop in the time needed for preparation. Retromesenteric para-aortic lymphadenectomy offers an excellent overview that lightens lymphadenectomy and therefore reduces the risks for patients.

Abstract
PURPOSE Enterobiasis is the most common parasitic disease of the temperate zones and infects the human intestinal tract. In rare cases extraintestinal infections with Enterobius vermicularis may occur and can affect the female genital tract and peritoneal cavity. In most cases the infection is asymptomatic, but there are also cases described in which peritoneal enterobiasis can cause abdominal pain. METHODS A case report and review of the pertinent literature. RESULTS A 32-year-old patient was admitted with cyclical lower abdominal pain. With suspected endometriosis a diagnostic autofluorescence laparoscopy (DAFE) was performed. At surgery extensive peritoneal deposits were seen. Macroscopically these deposits were not typical for endometriosis. The histological examination showed granuloma caused by E. vermicularis eggs. The patient was treated with mebendazole. After completion of treatment the patient was asymptomatic. At the second-look laparoscopy no more peritoneal changes were detected. CONCLUSION Enterobius vermicularis may cause symptoms similar to endometriosis. In cases with reasonable suspicion it should therefore be considered in the differential diagnosis.

Abstract
PURPOSE Malignant tumors of the parotid gland are very rare. Until now there have only been a few reported cases of patients with distant metastasis of breast cancer in the parotid gland. This case shows the rarity of the disease. METHODS This case is about a 74-year-old woman with an invasive lobular carcinoma of the left breast. The initial diagnosis was made four years ago. The operation which was done was a quadrantectomy and axillary lymph node dissection. It was followed by radiotherapy of the breast. The recommended chemotherapy was declined by the patient. RESULTS Three years after the initial diagnosis of lobular invasive breast cancer a nodular change in the cicatrice of the mastectomy occurred. The patient also had a contralateral peripheral facial paralysis, caused by a distant metastasis in the right parotid gland. CONCLUSIONS When there is a tumor in the parotid gland and a histological classified adenocarcinoma is found, the differential diagnosis of breast cancer metastasis should be considered.

Abstract
During recent years a continuous reduction of mortality from breast cancer has taken place in the Western countries. We wanted to verify whether the actual therapy for our own cases deviates from our recommendations, although the surgeon, radiotherapist and gynaecological oncologist are on the same premises. We sent out questionnaires to all newly diagnosed breast cancer patients in the last seven years regarding their adjuvant therapy. Comparing these answers to our own recommendation showed a very good compliance regarding chemotherapy and radiation therapy. Adjuvant endocrine therapy showed a very poor compliance with an adherence of 77%. Overall we can conclude that endocrine therapy causes many side-effects that seem to burden the patients. In combination with the duration of the therapy this causes a severe reduction in compliance and length of the therapy.

Abstract
Calpains, also called calcium activated neutral proteases (CANP), are expressed ubiquitously. They are intracellular, non-lysosomal cytoplasmic cysteine endopeptidases. Calcium is required for their activation. Their endogenous specific inhibitor is calpastatin, which is expressed ubiquitously and coexists within cells besides calpain. When calcium is present, calpastatin and calpain attach to each other inhibiting the protease. The calpain system plays an important role in many processes including apoptosis, necrosis, ischemia formation and exocytosis. So far, many reports exist on studies about the influence of calpains in different tumors (skin, breast, renal cell and prostate cancers). The role of calpains in pathogenesis or further tumor progression has always been proved in related studies, but their exact function could not be demonstrated. So far, no studies on calpains being involved in the pathogenesis of ovarian cancer have been published. In our study we focused on the expression of the enzymes calpain 1, calpain 2 and their inhibitor calpastatin in normal and malign ovarian tissue. Therefore, we performed immunohistochemical stainings of paraffin slices and evaluated staining intensity (SI), percentage of positive cells (PP) and immunoreactive score (IRS). We evaluated the correlation between enzyme expression in malign and benign ovarian tissues. In malignant ovarian tissue, we found decreased expression, staining intensity and immunoreactive score of calpastatin. With higher grading of the ovarian carcinoma, staining intensity and immunoreactive score of calpain 1 decreased. Staining intensity of calpain 2 in ovarian carcinoma decreased with increasing lymph node status. We clearly demonstrated differences between enzyme expressions in malign and benign tissue. This study could not find any specific function of calpains. Only few studies in the literature have been found that deal with calpain evaluation of ovarian cancer. Additional studies including more patients are required to elucidate the functional role and impact of calpain in tumors in detail.

Abstract
BACKGROUND The vitamin D metabolizing enzymes 25-, 1α- and 24-hydroxylase are expressed in malignant cells of the cervix and the ovaries. The aim of this study was to obtain further information about the regulation of the aforementioned enzymes by vitamin D, calcidiol and calcitriol in cervical and ovarian cancer. MATERIALS AND METHODS The human cervical adenocarcinoma cell line HeLa and the human ovarian adenocarcinoma cell line OVCAR-3 were incubated with vitamin D, calcidiol and calcitriol. The influence of vitamin D and its metabolites on the expression of 25-, 1α- and 24-hydroxylase was assessed by real-time RT-PCR. RESULTS Calcitriol significantly increased the 24-hydroxylase mRNA levels in HeLa and OVCAR-3 cells. The expression of 25- and 1α-hydroxylase was not regulated in a statistically significant manner. CONCLUSION These results suggest that in HeLa as well as OVCAR-3 cell lines, the metabolism of vitamin D is regulated via the expression of the catabolizing 24-hydroxylase.

Abstract
Ovarian carcinomas are associated with increased inflammation which is based upon an up-regulation of inducible cyclooxygenase-2 (COX-2). Moreover, based on our previous published data, the extra-renal vitamin D metabolism seems to be dysregulated in comparison to healthy tissue. In order to gain further insight into the prostaglandin (PG)- and vitamin D-metabolism in ovarian carcinomas, the study aimed to evaluate the expression of the PG metabolising enzymes COX-2 and 15-hydroxyprostaglandin dehydrogenase (15-PGDH) compared to the vitamin D receptor (VDR) in benign and malignant ovarian tissues. Additionally, we determined the 25-hydroxycholecalciferol (25(OH2)D3) serum levels. Expression of VDR, COX-2 and 15-PGDH was determined by Western blot analysis. Serum levels of 25(OH2)D3 and PGE2 were measured by chemiluminescence-based and colorimetric immunoassay. We detected significantly higher expressions of the PG metabolising enzymes 15-PGDH and COX-2 in malignant tissue and PGE2 serum levels were 2-fold higher in tumour patients. Furthermore, we found an inverse correlation to the VDR-expression which was 62.1% lower in malignant tissues compared to that in benign tissues. Surprisingly, we could not detect any differences between the 25(OH2)D3 serum levels in either group (n=20). These data suggest a correlation between PG- and vitamin D-metabolism in ovarian carcinomas.

Abstract
BACKGROUND Breast cancer is associated with inflammatory processes based on an up-regulation of cyclooxygenase-2 (COX-2) expression. The antiproliferative effects of calcitriol (1,25(OH)(2)D(3)) mediated via the vitamin D receptor (VDR) render vitamin D a promising target in breast cancer therapy. First data suggest a correlation between vitamin D and prostaglandin metabolism. MATERIALS AND METHODS We determined the expression of VDR, COX-2, 15-PGDH and the prostaglandin receptors EP(2)/EP(4) in normal and malignant breast tissue by real-time PCR and Western blot analysis, as well as 25(OH)(2)D(3) and PGE(2) plasma levels from healthy and breast cancer patients. RESULTS Significantly higher COX-2, lower VDR and lower EP(2) and EP(4) receptor protein levels in the malignant tissue and a significantly lower 15-PGDH protein level in normal breast tissue were detected. Breast cancer patients older than 45 years, diagnosed and sampled in the winter time had significantly lower 25(OH)(2)D(3) and higher PGE(2) serum levels. CONCLUSION The inverse correlation between VDR and both COX-2 and 15-PGDH, as well as between PGE(2) and 25(OH)(2)D(3) levels, suggests a possible link between VDR-associated target genes and prostaglandin metabolism.

Abstract
BACKGROUND It is known that 1,25(OH)2D3 can be metabolized to 1,24(OH)2D3 in breast tissue. This tissue-specific expression of 24-OHase may act as a pivotal link between vitamin D status (25(OH)D3 level) and the anticancer effects of 1,25(OH)2D3. Different expressions of the enzymes of vitamin D metabolism are found in breast cancer cells and tissues, and alternative splicing may play a role in biological functions and may cause tissue-specific variations. We describe the expression of vitamin D-1alpha-hydroxylase and vitamin D-24-hydroxylase in benign and malign breast tissues. We estimated that alternative splicing of the enzymes would lead to a catalytically dysfunctional product and may lead to a lower reduction of the target protein. MATERIAL AND METHODS Expression of 1alpha-OHase and 24-OHase RNA and protein was assessed using a real-time polymerase chain reaction (RT-PCR) and on protein level by Western blot in benign and malign breast tissue samples. RESULTS In breast cancer tissue the expression of 1alpha-OHase and 24-OHase were reduced significantly compared to benign breast tissue. CONCLUSION The results described above do not support results of previous studies. Alternative splicing of 1alpha-OHase and 24-OHase may regulate the levels of active enzyme but is more likely due to different cell types in samples with the result of testing a variety of tissue samples not purified benign and malign breast cancer cells. The significance of smaller variants in cells has not been clarified either, but it is known that they are not able to use 25(OH)D3 as a substrate to generate 1,25(OH),D3.

Abstract
Xanthogranulomas from the retroperitoneal space are rare. To our knowledge only a few cases have been reported in the literature in the retroperitoneal space. In this report, the authors present the case of a 24-year-old woman with a recurrence of this rare tumor. Two years after resection, the mass showed rapid local recurrence. Attention should be paid to the possibility of the transformation into a fibroxanthosarcoma, which could have an aggressive clinical course.

Abstract
BACKGROUND The human Mut-S-homolog-2 (MSH2) is part of the DNA mismatch repair system (MMR). Mutations in genes of the MMR are a predisposition to hereditary non-polyposis colorectal cancer (HNPCC). In women, MMR gene mutations may lead to primary endometrial cancer (EC). The important function of the MMR for the integrity of the DNA during replication makes it probable that the MMR might also be involved in the development and the course of sporadic carcinomas. Insufficient MMR activity or expression levels could be prognostic markers of the disease. PATIENTS AND METHODS Immunohistochemical analysis of MSH2 was performed in 86 tumor samples from patients with EC. RESULTS Compared to known tumor markers, namely estrogen and progesterone receptors, histopathological grading, TNM stage and FIGO classification, no significant correlation between MSH2 immunoreactivity and EC was found. CONCLUSION MSH2 immunohistochemical analysis is not of prognostic value for endometrial carcinoma.

Abstract
BACKGROUND Prostaglandins (PGs) within the periovulatory follicle are essential for various female reproductive functions such as follicular development and maturation. In animal models, granulosa cells express the PG synthesizing enzyme cyclooxygenase-2 (COX-2) and the PG inactivating enzyme 15-hydroxyprostaglandin dehydrogenase (15-PGDH). First references suggest a correlation between vitamin D and prostaglandin metabolism through the impact of 1,25(OH)2D3 (calcitriol) on the expression of COX-2 and 15-PGDH. MATERIALS AND METHODS The expression of COX-2, 15-PGDH and the vitamin D receptor (VDR) in human granulosa cells (COV434, hGC and HGL5), which were originally isolated from different stages of follicular maturation, was determined by real-time PCR (RT-PCR) and Western blot analysis. RESULTS A positive correlation of COX-2 and VDR protein was found in the COV434 and HGL5 cells and an inverse correlation of 15-PGDH and VDR protein levels in all the investigated cell types. CONCLUSION There may be a link between VDR, associated target genes and prostaglandin metabolism in human follicular maturation and luteolysis.

Abstract
Tissue-specific expression of 25-hydroxyvitamin D-1alpha-hydroxylase (1alpha-OHase) and vitamin D-hydroxylase (24-OHase) may act as the pivotal link between 25-hydroxyvitamin D3 (25(OH)D3) serum levels and the anticancer effects of 1,25-dihydoxyvitamin D3 (1,25(OH)2D3) and alternative splicing of the enzymes may regulate their biological function. The expression of 24-OHase in cells and breast tissue was investigated and its splice variants were detected. The expression of 24-OHase RNA and protein was assessed by RT-PCR followed by Western blot. The expression of 24-OHase was reduced by about 57% in MCF-7 breast cancer cells, compared to MCF-10F benign breast cells. In the Western blot, a signal at 56 kDa was found and further bands were detected at 42 and 44 kDa. In the breast cancer tissue, the expression of 24-OHase was reduced by about 58% compared to benign tissue. However, in the Western blot, only one signal was found in the benign tissue at 56 kDa, while in malignant tissue, a further band was detected at 40 kDa. Alternative splicing of 24-OHase may lead to a catalytically dysfunctional enzyme and may lead to less reduction of the target protein.

Abstract
BACKGROUND The antiproliferative effects of calcitriol (1,25(OH)2D3) mediated via the vitamin D receptor (VDR), render the biologically active form of vitamin D a promising target in breast cancer therapy. Furthermore, breast cancer is associated with inflammatory processes based on an up-regulation of cyclooxygenase-2 (COX-2) expression, the prostaglandin E2 (PGE2) synthesizing enzyme. The PGE2 metabolizing enzyme, 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is described as a tumor suppressor in cancer. First references suggest a correlation between vitamin D and prostaglandin metabolism through the impact of 1,25(OH)2D3 on the expression of COX-2 and 15-PGDH. MATERIALS AND METHODS The expression of VDR, COX-2 and 15-PGDH in benign MCF-10F and malignant MCF-7 breast cells was determined by real-time PCR (RT-PCR) and Western blot analysis. RESULTS Although the RT-PCR data were divergent from those obtained from the Western blot analysis, the COX-2 protein expression was MCF-7 2-fold higher in the MCF-7 compared to the MCF-10F cells. Moreover, a correlation of 15-PGDH to VDR by RT-PCR was found in both cell lines. The VDR protein levels were inversely correlated to the 15-PGDH protein levels and revealed that the MCF-10F cells had the highest VDR expression. CONCLUSION A possible link between VDR-associated target genes and prostaglandin metabolism is suggested.

Abstract
e16540 Background: Pseudomyxoma peritonei occurs mostly in conjunction with the type of intestinal mucinous borderline tumour and is characterized by building up a lot of mucus pour of cells. The most common tumor is the pseudomyxoma peritoneii with mucinous borderline tumours of the ovaries or with mucinous tumours of the appendix, normally without showing a rupture of the ovarian tumour pre- or intraoperatively. The diagnosis of pseudomyxoma peritonei is mainly difficult and guidelines for the treatment are unknown. Methods: In the period from 1991 to 2008, 52 patients with pseudomyxoma peritonei were treated by tumour debulking and intraoperative and intraperitoneal chemotherapy with Mitoxantron (40 mg in 300 ml of NaCl over 72 hours). During the tumour debulking a CUSA system was used. Results: The median follow-up was 8.2 years. There were the following histologies: mucinous cystadenoma of the ovary n = 29, mucinous cystadenoma of the appendix n = 10, mucinous cystadenocarcinoma n = 13. Reccurrences were seen in 4 patients. These patients were treated for reccurrences by the same way as mention above. All these patients were now without any recurrences. The other 48 patients are still alive with recurrences. Conclusions: The instillation of mitoxantron intraperitoneally and intraoperatively is an effective and safe therapy without any side effects after maximal tumour debulking of pseudomyxoma peritoneii. No significant financial relationships to disclose.

Abstract
BACKGROUND A novel immunoassay specific for the osteoclast-produced tartrate-resistant acid phosphatase TRAP isoform 5b was developed some years ago. By means of this assay, the usefulness of serum TRAP in monitoring the response to palliative treatment with clodronate in breast cancer patients with bone metastases was studied. Serum TRAP was examined for correlation with the activity of bone osteoclasts in these patients. MATERIALS AND METHODS Seventeen patients took part in this study taking 1600 mg clodronate daily as a tablet for five months. Eleven of these patients were evaluated. RESULTS TRAP activity correlated well with the grade of bone metastases and with the number of locations in the body. During the therapy with clodronate, TRAP activity in serum decreased. CONCLUSIONS We conclude that the measurement of TRAP is useful in monitoring treatment with bisphosphonate clodronate in patients with bone metastatic breast cancer.
