- Introduction: VWD-affected females often experience menorrhagia. Periodical fluctuations of the sex steroids during the menstrual cycle cause changes both in the coagulation and immune system. The aim of the current study was to assess the changes in selected inflammatory and endothelial markers in women with VWD during two phases of the menstrual cycle (follicular and luteal) and to compare it with corresponding data from healthy controls.Materials and methods: The study group included 12 VWD-affected females with regular menstrual cycle, with none of them being prescribed hormone treatment. They were not pregnant or breastfeeding. The control group consisted of 102 healthy females, matched for age and BMI.Results: Within the VWD group, endostatin was higher during the follicular phase, compared to the luteal phase, although the difference was not significant (p = 0.062). sICAM-1 and IL-6 were higher in VWD-affected females, compared to the controls, sVCAM-1, cathepsin S and sP-selectin were lower (p<0.003 for all cases). The pattern was constant throughout the menstrual cycle.Conclusions: Higher levels of endostatin during early follicular phase could potentially predispose women with VWD to the development of heavy menstrual bleeding, due to antiangiogenic properties and ability to suppress several coagulation factors. Lower p-selectin levels in VWD group, compared to controls, may also contribute to the bleeding tendency. Changes in other proteins, involved in angiogenesis are hypothetically related to the formation of angiodysplasia—common complication of VWF deficiency. The latter statement requires confirmation in larger studies.

- Introduction/Background Endometrial cancer (EC) is the most common gynaecological malignancy in Sweden. The disease has several prognostic factors. Still, the high amount of EC develops into more aggressive forms of cancer, even though being first considered to be non-aggressive. The LRIG proteins are a family of three integral surface proteins that have a similar domain organisation. The current study evaluated the role of LRIG proteins as prognostic biomarkers in EC.Methodology The cohort included 75 women who underwent a hysterectomy and bilateral salpingo-oophorectomydue to EC at the Department of Women's and Children's Health, Karolinska University Hospital Solna between 2007 and 2012. The expression of LRIG1, LRIG2, and LRIG3 in paraffin biopsies was analysed by immunohistochemistry (IHC) with applying specific polyclonal antibodies. Evaluation of immunostainings was performed by two senior pathologists without knowledge of the disease outcome. The percentage of positive cells was divided in two groups with median percentage as cut off to have two groups of equal size included in the statistical analysis. Then the groups were assessedin connection with different tumour characteristics and clinical outcomes of EC.Results The majority of women in the cohort had >50% LRIG1-, LRIG2-, and LRIG3-positive cells. Among 6047 person-months of follow-up a total, of 14 incident cases of relapsed EC were identified. A statistically significant association between high LRIG3 expression and superior overall survival was observed in the cohort (IRR=2.559, 95 CI=1.054–6.210, p=0.038). LRIG1 and LRIG2 expression did not significantly correlate with survival.Conclusion Our results support the hypothesis that LRIG3 expression may have a prognostic role in women with EC. The significance of LRIG1 and LRIG2 expression remains to be clarified.
