Second-Line Endocrine Treatment
1988
It was a milestone of cancer therapy in general when Huggins et al. [1] in 1941 first reported the beneficial clinical effects of bilateral orchiectomy in patients with prostate cancer, and the use of castration or estrogens as standard therapy remained the first- line treatment for many years. It was furthermore the beginning of a development which, over the following decades, led to the manipulation of testicular androgen synthesis and to attempts to eliminate other possible sources of male hormones.
Long-term effects of oral and transdermal hormone replacement therapy on plasma homocysteine levels.
2003
Objective To compare the long-term effects of oral and transdermal hormone replacement therapy (HRT) on serum homocysteine levels in postmenopausal women. Design An open, prospective, controlled study. Seventy-five healthy postmenopausal women were recruited as eligible for the study. Fifty women seeking HRT were randomized to receive continuous 17beta-estradiol, either by oral (2 mg daily; n = 25) or transdermal (50 microg daily; n = 25) administration, plus 10 mg dydrogesterone daily for 14 days of each 28-day cycle. Twenty-five women unwilling to receive hormone treatment received only calcium supplementation, representing the control group. Fasting blood samples were analyzed at baselin…
Reconstruction of Endometrium from Human Endometrial Side Population Cell Lines
2011
Endometrial regeneration is mediated, at least in part, by the existence of a specialized somatic stem cell (SSC) population recently identified by several groups using the side population (SP) technique. We previously demonstrated that endometrial SP displays genotypic, phenotypic and the functional capability to develop human endometrium after subcutaneous injection in NOD-SCID mice. We have now established seven human endometrial SP (hESP) cell lines (ICE 1-7): four from the epithelial and three from the stromal fraction, respectively. SP cell lines were generated under hypoxic conditions based on their cloning efficiency ability, cultured for 12-15 passages (20 weeks) and cryopreserved.…
Prognostic Influence of Pre-Operative C-Reactive Protein in Node-Negative Breast Cancer Patients
2014
The importance of inflammation is increasingly noticed in cancer. The aim of this study was to analyze the prognostic influence of pre-operative serum C-reactive protein (CRP) in a cohort of 148 lymph node-negative breast cancer patients. The prognostic significance of CRP level for disease-free survival (DFS), metastasis-free survival (MFS) and overall survival (OS) was evaluated using univariate and multivariate Cox regression, also including information on age at diagnosis, tumor size, tumor grade, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) status, proliferation index (Ki67) and molecular subtype, as well as an assessment of the…
CD1a down-regulation in primary invasive ductal breast carcinoma may predict regional lymph node invasion and patient outcome
2007
Aims: CD1a is a molecule belonging to the highlyconserved group of CD1 proteins. Its expression indendritic cells is related to the presentation of tumour-derived glycolipid antigens to T cells and, consequently,the development of a successful antitumour response.The aim was to investigate the presence of CD1a+ cellsin both primary tumours and lymph nodes (LN) ofa series of 35 invasive ductal carcinomas by bothimmunohistochemistry and reverse transcription-poly-merase chain reaction.Methods and results: CD1a antigen was more expressedin N0 than N1 breast cancer (P < 0.0001) in bothprimary lesions and LN metastases and correlatedpositively and significantly with oestrogen (ER) (P =0.0025) and…
Wertigkeit der Abradathistologie von Endometriumkarzinomen
2002
Objective: We compared immunohistological examination of endometrium biopsy specimen with the results of the immunohistological examination of tumor specimen to analyse the valence of this preoperative examination according to the clinico-pathological findings and overall-survival. Material and Method: Between 1985 and 1995 193 women were treated of an endometrial carcinoma at the University hospital Mainz. In this group we evaluated 41 patients with enough preoperative endometrial biopsy material for a retrospective immunohistochemical analysis and complete follow-up data. The materials from diagnostic curettage were stained and analysed for oestrogen and progesterone receptor status and f…
Immunohistochemical Detection of Hormone Receptors in Breast Carcinomas (ER-ICA, PgR-ICA): Prognostic Usefulness and Comparison with the Biochemical …
1994
In a prospective study conducted since 1983, the hormone-receptor status of primary breast carcinomas was investigated using immunohistochemical (ER-ICA, PgR-ICA) and biochemical (DCC) methods. The degree of immunohistochemical staining was evaluated according to the immunoreactive score (IRS) devised by Remmele and Stegner [Frauenarzt 28, 41-43 (1987)]. The findings obtained using the biochemical radioactive-ligand-binding assay (cutoff level, 20 fmol/mg) and those obtained using qualitative immunohistochemical methods were in agreement in 72.5% (ER-ICA) and 72.2% (PgR-ICA) of cases. For the 789 cases of primary breast carcinoma examined, postoperative data were available for a mean follow…
C-myc mRNA Expression in Epithelial Ovarian Carcinomas in Relation to Estrogen Receptor Status, Metastatic Spread, Survival Time, FIGO Stage, and His…
1998
Recently, it has been suggested that c-myc expression might correlate with estrogen receptor (ER) status and metastatic spread in ovarian cancer. In this study, expression of c-myc mRNA in 90 epithelial ovarian carcinomas was determined using the S1 nuclease protection assay. Expression of c-myc mRNA was detectable in 27 of 90 tumors. There was no significant association between c-myc mRNA expression and metastatic spread, survival time, FIGO stage, or histologic grade and type. C-myc mRNA was expressed in 45% of ER-positive tumors but only 24% of ER-negative tumors (p = 0.094; Fisher's exact test). Similarly, 44% of progesterone receptor (PR)-positive and 23% of PR-negative tumors expresse…
Disease expression in women with hereditary angioedema
2008
Udgivelsesdato: 2008-Jun-11 OBJECTIVE: Fluctuations in sex hormones can trigger angioedema attacks in women with hereditary angioedema. Combined oral contraceptive therapies, as well as pregnancy, can induce severe attacks. The course of angioedema may be very variable in different women. STUDY DESIGN: Within the PREHAEAT project launched by the European Union, data on 150 postpubertal women with hereditary angioedema were collected in 8 countries, using a patient-based questionnaire. RESULTS: Puberty worsened the disease for 62%. Combined oral contraceptives worsened the disease for 79%, whereas progestogen-only pills improved it for 64%. During pregnancies, 38% of women had more attacks, …
