What did it mean for eighteen- to twenty-year-old men and women in the nineteenth-century Netherlands to be confirmed—that is, to sit in the front row of the church, dressed in Sunday dress, and be accepted into full church membership? Previous scholarship on confirmation in the Netherlands Reformed Church has mostly focused on theological controversies surrounding the wording of the so-called confirmation questions (three questions about Christian doctrine and morals that confirmants had to answer during the service), treating these controversies as markers of growing struggles between ‘wings’ or ‘parties’ in nineteenth-century Dutch Protestantism. Important as these theological controversies were, this article nonetheless approaches confirmation from a different, less frequently explored angle, arguing that confirmation was also, and perhaps especially, a social rite of passage, which symbolically marked transition into a new stage of life, with adult responsibilities in church and society. Drawing on a rich array of published as well as unpublished sources (sermons, booklets, letters, and diaries), the article examines what kind of meanings were associated with this rite of passage, by both clergy and confirmants, and to what extent these meanings changed over the course of the century. It shows that Protestants throughout the nineteenth century tried to hold together, in one way or another, what one may call the ‘inward’ and the ‘outward’ aspects of the ritual (expressions of personal conviction and conformation to societal standards of morality). Although they insisted that professions of faith must be made “from the bottom of the heart,” they simultaneously equated confirmation with a promise to a virtuous life. Also, while accepting sighs and tears as testifying to the sincerity of a confirmant’s profession, many authors explicitly warned against strong emotions that could carry newly confirmed church members away from the narrow path of virtue.

Immunocytochemical detection of prognostic markers in breast cancer; technical considerations The purpose of this study was to establish a good technical procedure for immunocytochemical (IC) staining of prognostic markers in breast cancer specimens. The influence of various preparation, fixation and storage methods on ER, P53 and Ki-67 IC staining was assessed, using cells of two breast cancer cell lines T47D (ER/P53+) and ZR-75-ER (ER+, P53−). In addition we searched for a suitable transport medium. Depending on the technical procedure, great variations in expression of the tested antigens were found. Cytospins fixed and stored according to the Abbott method gave the best results. Histocon appeared to be the medium of choice. A good concordance of IC and immunohistochemical (IH) results was found when the adopted method was tested on material of 10 breast cancers. This study underlines the importance of quality controlled standardization of cell processing, fixation and storage of fine needle aspiration (FNA) aspirates in order to obtain reproducible and consistent IC results.

CD44 is a family of cell surface transmembrane glycoproteins members which differ in the extracellular part by sequences derived by alternative splicing of 10 variant exons (v1– v10). CD44 proteins containing such variant sequences have been implicated in tumor metastasis formation. Here, we have evaluated the expression of CD44 variants by immuno-histochemistry in primary breast cancer samples of 237 node-negative and 230 node-positive patients. For the analysis of samples derived from node-negative patients, the exon-specific antibodies used were DIII, vff7 and vff18 (v6), vff17 (v7/v8), fw11.24 (v9) and vff16 (v10). With the different antibodies which recognize v6 epitopes, the majority of tumors were positively stained (≥65% of the tumors) with varying intensities. Thirty-nine percent of the tumors were positively stained with the antibody vff16, and approximately half of the tumors with the antibodies vff17 and fw11.24. The expression of CD44 v6 epitopes in tumors from node-negative patients was associated with a favorable prognosis, both upon univariate and multivariate analysis. The expression of CD44 v7/8, v9 or v10 epitopes was not significantly related with relapse-free survival. Samples from node-positive patients were only examined with the antibodies vff7, vff17 and vff18. The staining with none of these antibodies was correlated with the length of relapse-free survival of the patients. Our data suggest that, generally, the usefulness of knowledge of CD44 variant expression is of limited value for assessing the risk of relapse in patients with primary breast cancer. However, the expression of exon v6 of CD44 may be a marker to identify patients with a relatively favorable prognosis in node-negative patients. Int. J. Cancer (Pred.

We investigated the feasibility and the anti-tumour activity of weekly cisplatin and the simultaneous application of local hyperthermia in patients with a pelvic recurrence of cervical cancer in previously irradiated area. Dose levels of cisplatin 60 mg m(-2), 70 mg m(-2) and 80 mg m(-2) were studied. Treatment objective of hyperthermia was the achievement of a tumour temperature of > or = 42 degrees for 60 min, during cisplatin administration. The protocol advised six weekly cycles of combined treatment. Nineteen patients, median age 47 years (range 26-71), were treated. A total of 89 cycles of combined treatment were administered. Even at the highest dose level of cisplatin, 80 mg m(-2) weekly, no dose-limiting toxicity was observed. Leucocytopenia at scheduled retreatment resulted in 1 or 2 weeks postponement in five cases. Neurotoxicity and renal toxicity were mild or absent. Maximum tumour temperatures achieved ranged 39.7-43.6 degrees C, mean 41.6+/-0.7 degrees C. All 19 patients were evaluable for response. One patient achieved a complete response that lasted 20 months, and nine patients achieved a partial response for a median duration of 6 months (range 4-50+ months), for an overall response rate of 53%. One patient subsequently underwent salvage surgery and currently remains free of disease at 4 years. We found that this combined hyperthermia-dose-intensive cisplatin regimen was well-tolerated. The true impact of the combination of cisplatin and locoregional hyperthermia can only be answered in a randomized study. Nonetheless, based on existing data on the poor efficacy of cisplatin in pelvic recurrent cervical cancer, we believe that the combined modality approach of weekly hyperthermia plus dose-intensive cisplatin is an attractive regimen, particularly if subsequent salvage surgery is available.

It has been shown that, in breast stroma, urokinase-type plasminogen activator (uPA) mRNA is predominantly expressed by myofibroblasts located at the invasive areas of the tumor. To examine which factors present in a tumor environment are candidates responsible for the induction of these uPA-producing myofibroblasts, we studied in vitro the capacity of a paired panel of normal and tumor-derived human breast fibroblasts to produce uPA protein and the myofibroblast marker alpha-smooth-muscle-actin (alpha-SMA) in response to various cytokines implicated in the process of tissue-remodeling during malignant transformation. We found that fibroblasts produced increased amounts of uPA protein after exposure to a-FGF, b-FGF, EGF, PDGF-BB, and IFN-gamma, were unaffected in this respect by IL-6, M-CSF, GM-CSF and Oncostatin M, and produced decreased amounts of uPA protein after exposure to IL-1alpha, TNF-alpha, IGF-I, and IGF-II. None of these cytokines were able to induce a striking increase in the fraction of alpha-SMA-positive fibroblasts. On the other hand, 25 pM TGFbeta1 increased the fraction of alpha-SMA-positive fibroblasts 5-fold in both normal and tumor-tissue-derived fibroblasts. Nonetheless, the normal-derived fibroblasts were unaffected in their uPA-producing capacity by TGFbeta1, and the tumor-derived fibroblasts produced decreased amounts of uPA protein after exposure to this cytokine, implying that at least in vitro the myofibroblast phenotype is not a prerequisite for the production of uPA by human breast fibroblasts. In addition, we established that the basal-uPA-production of both normal and tumor-derived fibroblasts was increased by autocrinely produced b-FGF-like activity, and that the basal-uPA-production of at least the normal-derived fibroblasts was decreased by autocrinely produced IGF-like activity. Altogether, our data suggest an active role for fibroblasts in the process of uPA-directed breast tumor proteolysis.

Elevated levels of expression of the urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1 have shown to be related to poor prognosis in a variety of cancer types. In the present study, cytosolic levels of uPA and PAI-1 were determined with enzyme-linked immunosorbent assays in cytosols prepared from 244 human ovarian tissues of different histological sub-types. Both uPA and PAI- I were significantly associated with the malignant progression of ovarian tissues; the levels were increased going from normal tissue, via benign and borderline adenomas, to primary and metastatic adenocarcinomas. For the 90 patients (34 early-stage and 56 patients with advanced disease) from whom the primary adenocarcinoma tissues were examined, uPA and PAI- I levels were evaluated for their association with clinicopathological parameters and with progression-free and overall survival. Neither uPA nor PAI-1 were significantly associated with the age of the patient, FIGO stage, tumor grade, tumor rest, the presence of ascites, or with progression-free or overall survival. On the other hand, age, FIGO stage/tumor rest and the presence of ascites, were significantly related to the length of both progression-free and overall survival in univariate analyses. Tumor grade was of prognostic significance in the analysis for progression-free survival, but not for overall survival. After adjustment for FIGO stage/tumor rest, only age retained its prognostic significance, in the analysis for progression-free survival and in that for overall survival.

A stromal fibroblast-mediated paracrine regulation of epithelial tumor cell proliferation and differentiation plays an important role in the development and progression of breast tumors. We have studied the paracrine growth regulation of various phenotypically different breast cancer cell lines using conditioned serum-free media (C-SFM) from primary breast fibroblasts. Fibroblast cultures were established from malignant primary tumors and adjacent normal breast tissue, benign fibroadenomas, cosmetic reduction mammoplasties and breast skin tissues. All fibroblast-conditioned media were shown to stimulate the proliferation of breast cancer cell lines. However, the C-SFM-induced MCF-7 proliferative response was shown to be significantly higher than the proliferative response observed with any of the other cell lines tested. More importantly, the MCF-7 proliferative response obtained with malignant tumor tissue fibroblast C-SFM was shown to be significantly higher than the response to C-SFM from paired (and unpaired) normal adjacent breast tissue fibroblasts. The MCF-7 proliferative response to fibroblast C-SFM from normal tissue (adjacent to the tumor) was further shown to be comparable to the MCF-7 response using benign or reduction mammoplastic tissue fibroblast C-SFM. In addition, we show that IGFs are only partly responsible for the observed proliferative effect of the C-SFMs, while EGF, TGF alpha and basic-FGF are shown not to be involved. We conclude that stromal fibroblasts can differentially regulate breast cancer cell proliferation. Both the fibroblast's tissue source as well as the target tumor cell's phenotype will determine the extent of the proliferative response.

The prognostic value of epidermal growth factor receptor (EGFR) expression and its biological role in estrogen receptor-positive (ER+) and ER-negative (ER−) primary breast cancer is controversial. In this study, distributions of ER, progesterone receptor and EGFR have been established using immunohisto-chemistry in both primary breast tumors and their matched axillary lymph node metastases of 26 patients or their matched distant metastases of 2 patients. In addition, 5 patients with bilateral breast cancer were studied. ER+ tumor cells were detected in 22 (69%) and EGFR+ tumor cells were detected in 11 (34%) primary breast carcinomas. Expression of ER and EGFR was inverse regarding the individual tumor cells in both primary tumors and metastases. Relationship of EGFR expression with poorly differentiated and large breast tumors was observed. Furthermore, primary tumors with a predominant lobular component were ER+ and, with one exception, EGFR−. Invasive ductal carcinomas were more frequently EGFR+. No apparent differences in receptor expression were observed between primary tumors and lymph node metastases or chro-nously or metachronously occurring bilateral breast cancers. Only one ER+ primary tumor showed a switch to EGFR expression in the involved lymph node. Our study shows that a shift in receptor phenotype between primary tumors and lymph node metastases is a rare event and, thus, additional analyses of involved lymph nodes will not likely serve as a better predictor for response to anti-estrogen therapy. We conclude that expression of EGFR is not a prerequisite for development of metastases. © 1995 Wiley-Liss, Inc.

Ki-67 immunoreactivity was studied in relation to immunohistochemically assessed expression of epidermal-growth-factor receptor (EGFR), estrogen receptor (ER) progesterone receptor (PgR) and cytosolic levels of cathepsin D in advanced human ovarian adenocarcinomas, borderline and benign cystadenomas and normal ovaries. A significantly higher number of Ki-67-positive cells were found in metastatic tumors vs. primary adenocarcinomas and in the total group of adenocarcinomas vs. benign/borderline cystadenomas. Cathepsin-D levels were also significantly higher in metastatic tumors than in primary adenocarcinomas, which in turn presented higher levels than were found in normal ovaries. However, no significant difference was observed between cathepsin-D levels in malignant adenocarcinomas and borderline/benign cystadenomas. Immunohistochemically assessed expression of ER and PgR was detected in variable percentages of epithelial tumor cells, and stromal cells were occasionally positive as well. In the group of primary adenocarcinomas, 46% were ER-positive and 34% were PgR-positive, although there was no significant difference between primary and metastatic lesions with respect to ER or PgR expression. Concordance between immunohistochemically assessed ER or PgR data and cytosolic ER and PgR levels measured with enzyme immunoassay was relatively low. EGFR, immunohistochemically assessed with MAb-EGFRI, was positive in 76% of the primary and in 78% of the metastatic adenocarcinomas. A strong positive association was detected between ER and PgR, and EGFR was observed to present a weak positive correlation with Ki-67 and ER. Cathepsin-D levels were not found to be significantly correlated with the expression of ER, PgR, EGFR or Ki-67. © 1994 Wiley-Liss, Inc.

The expression of oestrogen (ER), progesterone (PR) and androgen (AR) receptors in female breast cancer was investigated by immunohistochemistry on snap-frozen tissue specimens of a series of 100 breast cancers. For detection of the AR we used a recently developed mouse monoclonal antibody specific for the N-terminal domain of the human AR. Expression of AR was compared with that of ER and PR as well as with tumour grade and age. Of the breast cancers investigated, 76% were AR-positive. This high percentage corresponds well with previous data on AR expression in breast cancer determined with ligand-binding assays. In 53% of the tumours AR, ER and PR were present, while 9% of the tumours were positive for AR and negative for ER and PR. In 13% of the tumours no ER, PR or AR expression was seen; these were all grade-III tumours. A positive correlation was found between age and ER expression, but no correlation was seen between age and PR or AR. Future studies should establish the prognostic value of the combination ER, PR and AR determinations on female breast cancer with regard to biological behaviour and response rate to hormonal therapy. © 1992 Wiley-Liss, Inc.

Receptor status and gene amplification were studied in advanced human ovarian adenocarcinoma tissues, borderline and benign ovarian tumours and normal ovarian tissues. Sixty-five percent (53/82) of ovarian adenocarcinomas, 57% (8/14) of benign/borderline tumours and only 31% (5/16) of normal ovarian tissues studied showed specific 125I-EGF (epidermal growth factor) binding (median: 17; 10; and 0 fmol EGF-R/mg protein, respectively) and a significant increase in progesterone receptor (PgR) levels was observed in these groups (median: 5; 33; and 152 fmol/mg protein, respectively). No correlations were observed between the levels of EGF-R and the levels of either oestrogen receptors (ER) or PgR. All membrane samples of 25 adenocarcinomas studied by Scatchard analysis were positive for insulin-like growth-factor-1 receptors (IGF-1 -R) and contained higher IGF-I-R levels than membranes of 10 normal ovarian tissues, of which 9 were positive (median: 64 and 26 fmol IGF-I-R/mg membrane protein, respectively). Also, as measured by autoradiography, 37 adenocarcinoma tissues showed a higher expression of IGF-I-R (1.5+ to 4+) than sections derived from 10 normal ovarian tissues (I +). 125I-IGF-I binding was predominantly associated with epithelial tumour cells, the surrounding connective tissue was negative and in several samples high expression of IGF-I-R was found in areas of tumour necrosis. Southern blot analysis of DNAs isolated from 25 ovarian adenocarcinomas revealed no amplification of the IGF-I -R or the EGF-R gene. The HER2/neu gene was amplified only in 2 out of 3 histologically confirmed endometrioid adenocarcinomas studied but not in 22 other tumours. An amplification of the c-myc gene was observed in 28% (7/25) of the tumours. All c-myc-amplified tumours were PgR-negative. No rearrangement was observed for any of the genes studied. In conclusion, ovarian adenocarcinoma tissues show a decrease in PgR levels and an increased expression of IGF-I-R and EGF-R, in the absence of gene amplification, when compared to benign/borderline ovarian tumours and normal ovarian tissues. In addition, amplification of the c-myc and HER2/neu genes, without rearrangement of these genes, occurs in a minority of these tumours. © 1992 Wiley-Liss, Inc.

We reassessed renal biopsy specimens from 116 patients with systemic lupus erythematosus and clinical manifestations of lupus nephritis to determine the contributions of the World Health Organization classification system, the activity and chronicity indexes of the National Institutes of Health scoring system, and various clinical parameters at the time of biopsy to predicting disease outcome. Multivariate analysis showed that only a chronicity index greater than 3 was predictive for decreased renal survival, while age greater than 31 years at biopsy and a chronicity index greater than 3 were associated with decreased patient survival. Clinical tests of renal function were not reliable in discriminating between active lesions and chronic renal damage.

Thirty four cases of invasive breast carcinoma were analysed for heterogeneity of Ki-67 reactivity in a tumour, and proliferative activity in various histological subtypes was compared. The growth factions determined in areas of central and peripheral tumour were the same. Mucinous and lobular carcinoma showed lower Ki-67 activity than ductal carcinomas. When ductal carcinomas were subdivided according to their dominant growth pattern, the carcinomas with a solid or comedo growth pattern showed the highest proliferative activity. These results largely confirm data from previous cell kinetic studies on the incorporation of radioactively labelled thymidine. A correlation between the growth fraction determined by Ki-67 in fine needle aspiration smears and cryostat sections of corresponding tumours was shown, implying that the immunostaining of cytological smears gives a reliable impression of the growth fraction of a tumour and may therefore be used in prospective studies.

The purpose of this study was to establish a good technical procedure for immunocytochemical (IC) staining of prognostic markers in breast cancer specimens. The influence of various preparation, fixation and storage methods on ER, P53 and Ki-67 IC staining was assessed, using cells of two breast cancer cell lines T47D (ER/P53+) and ZR-75-ER (ER+, P53-). In addition we searched for a suitable transport medium. Depending on the technical procedure, great variations in expression of the tested antigens were found. Cytospins fixed and stored according to the Abbott method gave the best results. Histocon appeared to be the medium of choice. A good concordance of IC and immunohistochemical (IH) results was found when the adopted method was tested on material of 10 breast cancers.

Our data suggest that, generally, the usefulness of knowledge of CD44 variant expression is of limited value for assessing the risk of relapse in patients with primary breast cancer. However, the expression of exon v6 of CD44 may be a marker to identify patients with a relatively favorable prognosis in node-negative patients.

Elevated levels of expression of the urokinase-type plasminogen activator (uPA) and its inhibitor PAI-1 have shown to be related to poor prognosis in a variety of cancer types. In the present study, cytosolic levels of uPA and PAI-1 were determined with enzyme-linked immunosorbent assays in cytosols prepared from 244 human ovarian tissues of different histological sub-types. Both uPA and PAI-1 were significantly associated with the malignant progression of ovarian tissues; the levels were increased going from normal tissue, via benign and borderline adenomas, to primary and metastatic adenocarcinomas. For the 90 patients (34 early-stage and 56 patients with advanced disease) from whom the primary adenocarcinoma tissues were examined, uPA and PAI-1 levels were evaluated for their association with clinicopathological parameters and with progression-free and overall survival. Neither uPA nor PAI-1 were significantly associated with the age of the patient, FIGO stage, tumor grade, tumor rest, the presence of ascites, or with progression-free or overall survival. On the other hand, age, FIGO stage/tumor rest and the presence of ascites, were significantly related to the length of both progression-free and overall survival in univariate analyses. Tumor grade was of prognostic significance in the analysis for progression-free survival, but not for overall survival. After adjustment for FIGO stage/tumor rest, only age retained its prognostic significance, in the analysis for progression-free survival and in that for overall survival.

A stromal fibroblast-mediated paracrine regulation of epithelial tumor cell proliferation and differentiation plays an important role in the development and progression of breast tumors. We have studied the paracrine growth regulation of various phenotypically different breast cancer cell lines using conditioned serum-free media (C-SFM) from primary breast fibroblasts. Fibroblast cultures were established from malignant primary tumors and adjacent normal breast tissue, benign fibroadenomas, cosmetic reduction mammoplasties and breast skin tissues. All fibroblast-conditioned media were shown to stimulate the proliferation of breast cancer cell lines. However, the C-SFM-induced MCF-7 proliferative response was shown to be significantly higher than the proliferative response observed with any of the other cell lines tested. More importantly, the MCF-7 proliferative response obtained with malignant tumor tissue fibroblast C-SFM was shown to be significantly higher than the response to C-SFM from paired (and unpaired) normal adjacent breast tissue fibroblasts. The MCF-7 proliferative response to fibroblast C-SFM from normal tissue (adjacent to the tumor) was further shown to be comparable to the MCF-7 response using benign or reduction mammoplastic tissue fibroblast C-SFM. In addition, we show that IGFs are only partly responsible for the observed proliferative effect of the C-SFMs, while EGF, TGF alpha and basic-FGF are shown not to be involved. We conclude that stromal fibroblasts can differentially regulate breast cancer cell proliferation. Both the fibroblast's tissue source as well as the target tumor cell's phenotype will determine the extent of the proliferative response.

Neurologic complications of both the central and peripheral nervous systems occur frequently in patients with primary Sjogren's syndrome (primary SS), but the underlying cause of these complications is unknown. We studied the presence of antineuronal antibodies in relation to neurologic complications in a consecutive series of 45 patients with primary SS. Twenty-five patients had neurologic complications: 12 patients with polyneuropathy, three with psychiatric disorders, four with carpal tunnel syndrome, seven with migraine, seven with myalgia, and four with other complications (transverse myelitis, stroke, Bell's palsy, and pyramidal signs). Ten patients had more than one neurologic complication. Eleven patients had major and 14 had minor complications according to criteria used for rating neurologic complications in patients with systemic lupus erythematosus. Antineuronal antibodies were present in six of 11 (55%) patients with major neurologic complications and in four of 34 (11%) of patients without major neurologic complications (p = 0.001). This difference could be attributed mainly to the group of patients with polyneuropathy. Three of the 10 sera of patients with positive antineuronal antibodies had antibodies reacting with a 38-kd neuronal protein on immunoblotting, identical to the anti-Hu antibody reactivity in paraneoplastic neurologic disease associated with small-cell lung cancer.

To evaluate the sensitivity and specificity of immunohistochemical analysis in relation to the standard cytological examination of the cerebrospinal fluid (CSF) in patients with either a solid tumour or a haematological malignancy and possible leptomeningeal disease, 68 CSF-samples derived from 68 patients were examined. The sensitivity of immunohistochemical analysis was 0.54 and its specificity 0.98. Only one patient had a positive immunohistochemistry and a negative cytology. The gain of adding immunohistochemistry to cytology is nearly 8%. It is concluded that immunohistochemistry should not be used as a screening test for leptomeningeal disease in patients with cancer.

During this century many immigrants from Mediterranean and African countries have moved to western Europe.1 Second and third generations often face a conflict. They may follow the lifestyle of the new country and friends but have to remain mindful of the original traditions and attitudes of their families. Many immigrant groups hold strongly with the tradition that girls must be virgins when they marry. If the bride cannot show her bloody sheet after the wedding night, her family are shamed. Her new husband's family may exact revenge in the form of violent reprisals and banishment of the bride. Because of these far reaching consequences, many gynaecologists in the Netherlands are willing to …
