Surgical menopause increases salt sensitivity of blood pressure.

Salt sensitivity of blood pressure is associated with an elevated risk of developing hypertension (HTN) and is an independent risk factor for cardiovascular disease. The prevalence of HTN increases after menopause. The aim of this study was to investigate prospectively whether the loss of ovarian hormones increases the occurrence of salt sensitivity among healthy premenopausal women. We enrolled 40 normotensive, nondiabetic women (age 47.2+/-3.5), undergoing hysterectomy-oophorectomy for nonneoplastic processes and not on hormone replacement, to determine the effect of changes in sodium intake on blood pressure the day before and subsequently 4 months after surgical menopause. Salt loading was achieved using a 2-L normal saline infusion and salt depletion produced by 40 mg of intravenous furosemide. A decrease >10 mm Hg in systolic blood pressure between salt loading and salt depletion was used to define salt sensitivity. Before and after menopause, salt-sensitive women exhibited higher waist/hip and waist/thigh ratios (P<0.01). Although all of the women remained normotensive, the prevalence of salt sensitivity was significantly higher after surgical menopause (21 women; 52.5%) than before (9 women; 22.5%; P=0.01), because 12 (38.7%) salt-resistant women developed salt sensitivity after menopause. In summary, we demonstrated that the prevalence of salt sensitivity doubled as early as 4 months after surgical menopause, without an associated increase in blood pressure. Epidemiological studies indicate that development of HTN may not occur until 5 to 10 years after menopause. The loss of ovarian hormones may unmask a population of women prone to salt sensitivity who, with aging, would be at higher risk for the subsequent development of HTN and cardiovascular disease.

Predictors of incident diabetes, metabolic syndrome in middle-aged adults: a 10-year follow-up study from Kinmen, Taiwan.

AIMS/HYPOTHESIS: The aim of this prospective study was to assess a population-based cohort for the predictors of incident diabetes and metabolic syndrome, which is most likely to lead to cardiovascular disease. METHODS: We compared the baseline individual components of metabolic syndrome, adopted from the NCEP ATP III for Asians, in 3629 subjects who developed diabetes, metabolic syndrome, or diabetes and metabolic syndrome to those who remained free of diabetes and metabolic syndrome for 10 years. RESULTS: The incidence rate of diabetes was 7.8% (9.8% in men and 6.3% in women, respectively), and metabolic syndrome was 24.2% (23.4% in men and 24.7% women, respectively). Eighty-five men and 99 women developed diabetes and metabolic syndrome, which yielded incidence rates of 5.7% in men and 4.7% in women. After adjustment for related covariable factors, each component of metabolic syndrome in women, higher triglyceride and greater waist circumference in men, independently predicted future incident diabetes and metabolic syndrome as compared with those who remained free of diabetes and metabolic syndrome. CONCLUSIONS/INTERPRETATION: These findings suggest that several components of metabolic syndrome independently precede the development of diabetes and metabolic syndrome. Further intervention studies are required to demonstrate the benefits of intervention with all aspects in decreasing the incidence of diabetes and metabolic syndrome in the general population.

EGF-R and erbB-2 in murine tooth development after ethanol exposure.

BACKGROUND: Alcohol consumption during pregnancy can frequently lead to a congenital disorder known as fetal alcohol syndrome (FAS); however, not all children born to alcoholic women develop FAS. Alcohol consumption may affect diverse organs and systems during embryonic development, including craniofacial structures. Small teeth, enamel alterations, and delayed eruption have been observed after ethanol exposure. Epidermal growth factor receptors (EGF-Rs) participate in dental proliferation and differentiation, and changes in these receptors were considered here to be a likely mechanism associated to the dental anomalies observed in this syndrome. Epidermal growth factor receptor type 1 (EGF-R) and epidermal growth factor receptor type 2 (erbB-2) immunoexpression during the lower first molar morphogenesis was investigated in mouse fetuses exposed to ethanol during gestation. METHODS: Pregnant female mice were divided into groups, consuming either 5, 10, 15, 20, or 25% ethanol solutions, or water (control group). Heads were obtained from 16.5- and 18.5-day fetuses. Immunohistochemistry was applied to EGF-R and erbB-2. RESULTS: At days 16.5 and 18.5, fetuses from 15%, 20%, and 25% ethanol groups showed delayed differentiation, degenerative changes in dental epithelial tissues and reduced dental size; additionally, they displayed an enhanced immunoreactivity to EGF-R and erbB-2. CONCLUSIONS: Our results suggest that ethanol consumption during pregnancy affects the expression of EGF receptors and induces a delay in murine fetal dental morphogenesis. Dental development is a process that involves a number of growth factors; hence we consider that further research is required to show whether the changes in glycosylation and growth-factor signaling pathways observed in other cells are also involved in the alterations observed in this study.

Becoming bicultural: Chinese American women and their development.

Ethnic and racial diversity in the United States has led to increasing interest in research on biculturalism, yet the meaning and underlying processes of biculturalism in the context of development in young adults are not well understood. Fifteen interviews were conducted with second-generation Chinese American women to explore how being bicultural fit into their lives. Data analysis yielded a developmental map that reflected their experiences throughout life as minority women. Findings suggest that biculturalism is more than being functionally competent in two cultures, it is both a behavioral and psychological orientation in life. From the findings of this study, we have increased our knowledge of Asian American women's development and provided a foundation for nursing research with minority women.

Hormone replacement therapy in the menopause.

The failure of follicular development that characterizes the menopause leads to a marked reduction in serum levels of estradiol and progesterone. As a result, the majority of women develop symptoms, including hot flushes, sleep disturbance, and vaginal dryness. Long-term consequences of ovarian insufficiency include genital atrophy, osteoporosis, and increased rates of myocardial infarction. Estradiol replacement (ERT) has proved effective in treating and preventing these problems. ERT has, however, led to increased risk of endometrial carcinoma. Consequently, treatment regimens now include progestins (HRT) to protect women who have a uterus. Progestins act by down-regulation of estradiol receptor activity, which is an advantage for preventing endometrial hyperstimulation, but a potential disadvantage when beneficial effects of estradiol are opposed. Current menopause health care includes assessment, treatment, and follow-up. Signs and symptoms of estradiol deficiency are evaluated during initial history-taking and physical examination. The MENSI (Menopause Symptom Index) has proved an efficient questionnaire for both initial assessment and monitoring of treatment effects. Vaginal cell maturation index (M.I.) can be helpful in determining need for hormonal treatment and for assessing response to treatment. A "therapeutic range" for ERT can be achieved with the availability of a variety of hormone preparations administered in different ways (oral, transdermal, skin gel, implants, etc.), thus avoiding the problems of both inadequate and excessive hormonal doses. This paper will describe a structured approach to the delivery of health care in the menopause.

Fifteen percent of myocardial infarctions and coronary revascularizations explained by family history unrelated to conventional risk factors. The Reykjavik Cohort Study.

Aims To examine the relationship between history of myocardial infarction in first-degree relatives and the risk of developing coronary heart disease (myocardial infarction or coronary revascularization). Methods and Results A total of 9328 males and 10062 females, randomly selected residents of the Reykjavik area, aged 33-81 years, were examined in the period from 1967 to 1996 in a prospective cohort study. Cardiovascular risk assessment was based on characteristics at baseline. Information on history of myocardial infarction in first-degree relatives was obtained from a health questionnaire. Mean follow-up was 18 and 19 years for men and women, respectively. During follow-up 2700 men and 1070 women developed coronary heart disease. Compared with subjects without a family history, the hazard ratio of coronary heart disease was 1.75 (95% confidence interval, CI, 1.59-1.92) for men and 1.83 (95% CI, 1.60-2.11) for women, with one or more first-degree relatives with myocardial infarction. The risk factor profile was significantly worse in individuals with a positive family history. After allowance for these risk factors, the hazard ratio was still highly significant, 1.66 (CI, 1.51-1.82) and 1.64 (CI, 1.43-1.89) for men and women, respectively. Family history of myocardial infarction was attributed to 15.1% of all cases of coronary heart disease in men and 16.6% in women, independent of other known risk factors. Conclusion Family history of myocardial infarction increases the risk of developing coronary heart disease in both men and women and is largely independent of other classic risk factors. Approximately 15% of all myocardial infarctions can be attributed to familial factors that have not been measured in the study or remain to be elucidated.

Titrated oral misoprostol solution--a new method of labour induction.

BACKGROUND: Misoprostol, a cheap, stable, orally active prostaglandin analogue, is effective for labour induction when administered either vaginally or orally, but uterine hyperstimulation and rupture have been reported. Previous studies of oral misoprostol for labour induction have used fixed dosages 3-6-hourly. OBJECTIVES: To develop a new method of misoprostol use for labour induction using very small, frequent, titrated oral dosages, and to pilot effectiveness. STUDY DESIGN: Open clinical pilot study. SETTING: Coronation Hospital, an academic hospital in Johannesburg, South Africa. METHODS: We developed a method using 2-hourly titrated misoprostol doses commencing with 20 micrograms, increased after three doses to 40 micrograms. To administer such small doses we dissolved one misoprostol tablet in 200 ml water. A pilot study of this method was undertaken in 25 women with various indications for induction of labour. RESULTS: Eighteen women (72%) delivered vaginally within 32 hours of induction and two women developed uterine hyperstimulation. The caesarean section rate was 20%. CONCLUSIONS: Women may respond to much smaller dosages of misoprostol than are currently in use. A multicentre randomised trial of this method is underway. We emphasise the dangers inherent in the current unregistered use of misoprostol in clinical practice.

Participatory health communication and action through women groups in rural areas.

Twelve women groups in 10 villages of block Beri were identified and activized through participatory health communication actions for mother and child development. Women could undertaken responsibilities on key health problems concerning mothers and children. In these villages over 58% of antenatal mothers now used home made clean packets for delivery and chose right place for delivery. Most of them (60%) now initiate breast feeding immediately after delivery as against 23% in the year 1988. Over 54% of women now drink chlorinated water and almost same proportion used sugar salt solution in diarrheal diseases. Thus women have become self reliant in chlorination of wells and pots as also in diarrheal diseases management. Practice of hand washing has been almost universalized.

Incidence of diabetes mellitus in women following impaired glucose tolerance in pregnancy is lower than following impaired glucose tolerance in the non-pregnant state.

Impaired glucose tolerance (IGT), which is asymptomatic and requires a glucose tolerance test for detection, is a well-known risk factor for diabetes mellitus. Outside the research setting it is rarely identified in people who lack specific risk factors for diabetes except during pregnancy, at which time screening with an oral glucose challenge is a routine procedure. A 75-g oral glucose tolerance test was performed during the latter part of pregnancy or during a routine epidemiology survey in 15-39-year-old Pima Indian women with no history of abnormal glucose tolerance. Those with IGT by World Health Organization criteria were included in this study. Diabetes incidence in women was compared between those whose IGT was first detected during pregnancy and those who were not pregnant when IGT was first recognized. Seventeen of 73 pregnant women and 114 of 244 non-pregnant women developed diabetes within 10 years. When controlled for plasma glucose concentration, age, body mass index, parity and duration of follow-up, those who were not pregnant were at higher risk of developing diabetes than those who were pregnant (hazard rate ratio = 1.71, 95% confidence interval = 1.01-2.91). Previous studies had reported that women with IGT during pregnancy are at higher risk of diabetes than women with normal glucose tolerance. This study suggests that women with IGT during pregnancy are at lower risk than non-pregnant women with a similar plasma glucose concentration who, in the clinical setting, are likely to remain unrecognized.

Effect of second vaginal delivery on anorectal physiology and faecal continence: a prospective study.

BACKGROUND: Because obstetric injury to the anal sphincters may be occult, and because the mechanism of injury differs between first and subsequent deliveries, we prospectively assessed the effects of first and second vaginal deliveries on anal physiology and continence. METHODS: We undertook a prospective observational study of 59 previously nulliparous women through two successive vaginal deliveries by means of a bowel-function questionnaire, and an anorectal-physiology assessment, both antepartum and 6-12 weeks post partum. FINDINGS: 13 (22%) women reported altered faecal continence after their first vaginal delivery: eight had persistent symptoms during their second pregnancy, of whom seven deteriorated after the second delivery; five regained continence before their second pregnancy, but two became incontinent again after the second delivery. Five women developed incontinence for the first time after their second vaginal delivery, of whom three had occult primiparous sphincter injury. 20 (34%) women, seven of whom had no symptoms, had anal-sphincter injury as a result of their first delivery, but only two new injuries occurred after the second vaginal delivery (p=0.013). Although pudendal neuropathy was no more common after the second than after the first vaginal delivery (15 vs 19%, p=0.8), pudendal-nerve latency was longer after the second delivery (p=0.02). INTERPRETATION: Primiparous women with persistent symptoms of altered faecal continence experience deterioration after a second vaginal delivery. Women with transient faecal incontinence or occult anal-sphincter injury after their first vaginal delivery are at high risk of faecal incontinence after a second vaginal delivery. The risk of mechanical anal sphincter injury is greatest after the first delivery.

Patterns of breast recurrence in a pilot study of brachytherapy confined to the lumpectomy site for early breast cancer with six years' minimum follow-up.

PURPOSE: In this pilot study of high-dose-rate brachytherapy to the lumpectomy site as the sole radiation, ipsilateral and contralateral breast recurrences are documented with specific attention to the location of recurrence relative to the lumpectomy site. METHODS: Between March 1992 and January 1996, 39 patients with T1 (32 patients) and T2 breast cancers received 37.2 Gy in 10 fractions (b.i.d.) over 1 week prescribed to a volume encompassing the surgical clips. Thirteen received adjuvant tamoxifen, and 4 received chemotherapy. Follow-up included annual bilateral mammograms and clinical breast examination every 3 to 6 months. Whereas 13 patients had intraoperative implantation of the lumpectomy site, 26 had postoperative implantation. The latter group and 7 of the former group had surgical clips marking the lumpectomy site, which allowed estimates of the distance of any ipsilateral breast recurrence from the lumpectomy site, using the mediolateral and cranio-caudad mammographic views. RESULTS: At a median follow-up of 91 months, 33 women are alive, 4 have died of disease, and 2 have died of other causes. The 5-year actuarial rate of ipsilateral breast recurrence was 16.2%. Of 6 ipsilateral recurrences, 2 occurred within the lumpectomy site (in-field recurrences). One of the 2 patients had a 1-mm microscopic margin at initial diagnosis; the recurrence was a 3.5-mm microscopic focus of duct carcinoma in situ. The other patient had a 1.5-cm, high-grade infiltrating mammary carcinoma with no residual at wider resection at first diagnosis; the 5-mm invasive recurrence was also of high grade. Four women developed invasive recurrences at least 1.6 cm or more from the lumpectomy site (out-of-field recurrences). Two of these women had gross multifocal recurrences with two cancers in each patient; 1 of the 2 patients had an extensive intraductal component at initial diagnosis. The estimated nearest distances between the out-of-field recurrences and the surgical clips were 1.6, 5.5, 7.7, and 12.0 cm. All ipsilateral breast recurrences were salvaged by mastectomy (4 patients) or by repeat lumpectomy (2 patients) and whole-breast radiation. The interval postdiagnosis to ipsilateral recurrence ranged from 20 months to 58 months. There were two contralateral breast recurrences at intervals of 34 and 36 months; 1 of these patients also had a multifocal, ipsilateral recurrence at 58 months, as previously described. Among patients with any breast recurrence, 1 patient had a family history of prostate cancer; there was no family history of breast or ovarian cancer. Of 17 patients who received adjuvant systemic therapy, only 1 had a breast recurrence. CONCLUSIONS: In this pilot study, breast recurrences outside of the lumpectomy site were the predominant pattern of recurrence.

Serum sex hormone levels after menopause and subsequent breast cancer.

BACKGROUND: High levels of androgens and estrogens have been reported to be associated with breast cancer. However, the multiplicity of factors that influence hormone levels and methodologic issues complicate the study of the relationship between steroid sex hormones and breast cancer. PURPOSE: Using an improved study design, we assessed prospectively the relationship between the principal steroid sex hormones in serum and the subsequent occurrence of invasive breast cancer in postmenopausal women. METHODS: Four thousand fifty-three healthy postmenopausal women aged 40-69 years, were enrolled from June 1987 through June 1992 in a prospective investigation of hormones and diet in the etiology of breast tumors (ORDET study) as part of a larger volunteer cohort of 10 788 premenopausal and postmenopausal women from Varese Province, northern Italy. At recruitment, blood samples were taken between 8:00 AM and 9:30 AM (after overnight fasting), and sera were preserved in -80 degree Celsius freezers. Women who had received hormone treatment in the 3 months prior to enrollment, who had bilateral ovariectomy, or who had a history of cancer or liver disease were not recruited. Twenty-five women in the final eligible cohort of postmenopausal women developed histologically confirmed, invasive breast cancer during the first 3.5 years of follow-up for the cohort (13 537 women-years). For each case subject, four control subjects were randomly chosen after matching for factors possibly affecting hormone preservation in serum. One case subject and eight control subjects were excluded because premenopausal hormonal patterns were found; thus, after also excluding the four control subjects matched to the ineligible case subject, we included 24 case and 88 control subjects. In the spring of 1994, stored sera of case and control subjects were assayed in a blinded manner for dehydroepiandrosterone sulfate and estradiol (E2) by in-house radioimmunoassay and for total and free testosterone and sex hormone-binding globulin by commercially available nonextraction iodination kits. Mean differences in risk factors were tested by analysis of variance for paired data. Relative risks (RRs) were estimated by conditional logistic regression analysis. All P values resulted from two-sided tests. RESULTS: Age-adjusted mean values of total testosterone, free testosterone, and E2 were significantly higher in case subjects than in control subjects: total testosterone, 0.34 ng/mL versus 0.25 ng/mL (P<.001); free testosterone, 1.07 pg/ml versus 0.77 pg/mL (P= .006); and E2, 25 pg/mL versus 22 pg/mL (P= .027). Age-adjusted RRs for breast cancer in increasing tertiles were as follows: for total testosterone, 1.0, 4.8, and 7.0 (P for trend =.026); for free testosterone, 1.0, 1.8, and 5.7 (P for trend=.005); and for total E2, 1.0, 7.1, and 5.5 (P for trend= .128). CONCLUSIONS AND IMPLICATIONS: This prospective study provides further evidence in support of the already established association between elevated estrogen levels and breast cancer. Even more importantly, it provides new evidence that high serum testosterone levels precede breast cancer occurrence.

Dopamine supersensitivity and hormonal status in puerperal psychosis.

BACKGROUND: We examine the dopamine receptor supersensitivity hypothesis of puerperal psychosis, and explore puerperal changes in the functional sensitivity of this receptor system. METHOD: Dopamine receptor sensitivity was estimated using growth hormone (GH) response to apomorphine challenge following delivery in 37 control women, and 11 deliveries in 10 women at 'high risk' of puerperal psychosis (previous history of puerperal affective or non-puerperal manic psychosis). Tests were on days 4 or 5, 11 or 12 and at six weeks postpartum. RESULTS: Three women developing puerperal psychosis had subsensitive GH responsiveness on day 4. GH response to 67 challenge tests (in control and 'high risk' women) increased between days 4 or 5 and six weeks postpartum (P < 0.05). GH response at six weeks correlated with free thyroxine levels (P < 0.01). CONCLUSIONS: These three cases do not support the stated hypothesis. Hypothalamic dopamine receptor sensitivity increases during the puerperium; thyroxine might influence this.

Breastfeeding, work and women's health among Thai women in Chiang Mai.

Reconciling the conflicting rights and demands of women's productive and reproductive roles poses an increasing challenge to health policy formulation. This article derives from a combined qualitative and quantitative study conducted in Chiang Mai, Thailand. It discusses situations and difficulties relevant to the health of employed women who breastfed their infants. Three hundred and thirteen employed women were interviewed to explore their experiences as mothers, particularly their attempts to balance the demands of work and breastfeeding. The findings demonstrate the stresses and conflicts in combining breastfeeding with work that can affect both physical and emotional health. Some women developed negative feelings. Exhaustion or fatigue, lack of self care and not eating properly were the common physical problems reported by women in this study.

Asthma and rhinitis induced by exposure to raw green beans and chards.

BACKGROUND: Although the vast majority of IgE-mediated allergic reactions to foods occurs through ingestion, a few cases of unexpected allergic reactions to foods may occur through the exposure to airborne food allergen particles. METHODS: Case reports. Skin prick tests and serum-specific IgE (CAP-FEIA) were used to identify specific IgE antibodies. Bronchial provocation tests were performed to determine the clinical relevance of inhaled exposure to raw and cooked green beans and raw chards. After demonstrating specific reactivity to them, SDS-PAGE and immunoblotting of raw and cooked green beans were carried out to identify relevant antigens. RESULTS: Three women developed bronchial asthma and rhinitis after exposure to raw green beans, and one of them also when exposed to raw chards. All women tolerated ingestion of green beans. Patients reported multiple episodes while handling these vegetables for cooking activities. Allergy to green beans and chards was demonstrated by skin testing and serum-specific IgE. Bronchial challenge test with these allergens showed positive responses to raw, but not cooked, green beans and chards. Oral food challenges with green beans (raw and cooked) and chards were negative in all patients. In order to further characterize the allergenic components of these extracts, SDS-PAGE and electroblotting studies were also performed. Immunoblots of raw and cooked green beans extract showed two IgE-binding bands with apparent molecular weights of 41.1 and 70.6 kD. Interestingly, a 47-kD IgE-binding protein was detected only in raw green bean extracts. CONCLUSIONS: We report three patients who developed asthma and rhinitis caused by exposure to raw, but not to cooked, green beans and chards in a non-occupational environment. Only minor differences of IgE reactivity between nitrocellulose-blotted raw and boiled green bean extract were found.

Measuring battering: development of the Women's Experience with Battering (WEB) Scale.

Measuring only the physical markers of violence (e.g., slapping, beating) fails to capture the chronic vulnerability and gendered nature of battered women's experiences. Instruments that measure only observable discrete events may mask the continuous nature of battering and the relation between events and experience. Our approach to measuring battering operationalizes the experiences of battered women rather than the abusive behaviors they encounter. This alternative approach emphasizes the meanings battered women attach to the violence and to battering as an enduring presence in their lives. Focus groups with 22 battered women generated qualitative data for developing scale items (Smith, Tessaro, & Earp, 1995) and a known-groups survey with 185 battered and 204 nonbattered women determined the final scale items. Factor analysis of 40 initial items revealed a strong single-factor solution. The resulting 10-item Women's Experiences with Battering (WEB) Scale demonstrated high internal consistency reliability, was significantly correlated with known-group status, exhibited good construct validity, and was not significantly correlated with a measure of social desirability. The WEB Scale provides researchers with a valid and concise measure for studying relations between battering and health or health behavior, as well as evaluating the impact of interventions on battered women or prevalence.

The effects of gender on clinical and neurological outcomes after acute cervical spinal cord injury.

The potential clinical relevance of gender on clinical and neurological outcome after spinal cord injury (SCI) has received little attention. In order to address this issue, we examined all consecutive cases of acute traumatic cervical SCI admitted to our institution from 1998 to 2000. There were 38 males (ages 17-89 years, mean of 51.6) and 17 females (ages 18-84 years, mean of 63.2). Both groups were comparable regarding level (C1 to C7) and severity of SCI (ASIA A to D) at admission. Age differences between the groups approached significance (p = 0.057), and thus this factor was treated as a covariate in the analysis. Co-morbidities were as frequent in men (86.8%) as in women (76.5%). The therapeutic approaches, length-of-stay in the acute care unit, mortality, and discharge disposition were similar in men and women. During hospitalization, 44.7% of men and 52.9% of women developed post-SCI secondary complications without any significant gender-related differences. Both groups showed a similar incidence of infections, cardiovascular complications, thromboembolism, and pressure sores. Univariate analysis revealed a trend for higher incidence of psychiatric complications (p = 0.054) and deep venous thrombosis (p = 0.092) in women, which was confirmed by multivariate analysis. Neurological outcome was not correlated with gender. A similar number of males and females (42.1%, 47.1%) showed evidence of neurological recovery as revealed by an improvement in ASIA scores. Moreover, 18.4% of males and 29.4% of females recovered to ASIA E status. Our data suggest a shift in the demographics of acute SCI with an increasing incidence in elderly women. Although neurological outcomes were not significantly related to gender, we observed a trend for higher rates of reactive depression and deep venous thrombosis in women. These issues may be of key clinical importance in developing improved management protocols for SCI so as to maximize functional recovery and quality-of-life.

Metaplastic carcinomas of the breast: V. Metaplastic carcinoma with osteoclastic giant cells.

The clinical and pathologic features of 29 examples of mammary metaplastic carcinoma with osteoclastic giant cells (OGC) in the stroma are reported. A bland spindle cell or sarcomatous component dominated these neoplasms, although infiltrating duct carcinoma was present in 23 cases, and intraductal carcinoma was present in six cases. In all 29 neoplasms, the carcinoma was admixed or contiguous with the stroma. Osteoclastic giant cells were admixed within the cellular stroma, and were intimately associated with prominent thin-walled vessels. Hemorrhage and hemosiderin deposition were common. Osteoclastic giant cells were immunoreactive for vimentin and, to a lesser extent, actin, and uniformly not immunoreactive for keratins, confirming their mesenchymal nature. The stromal component of 63% of neoplasms tested was immunoreactive for keratin, 33% was immunoreactive for epithelial membrane antigen, 54% reacted for S-100 protein, 84% reacted for actin, and 100% was immunoreactive for vimentin. Nineteen neoplasms had osteoid, bone, or cartilage, but these were a prominent component in only five neoplasms and OGC were not limited to these areas. The disease-specific cumulative 5-year survival rate for patients with metaplastic carcinoma with OGC was 68%, similar to rates for patients with matrix-producing carcinoma (68%), spindle cell carcinoma (64%), and squamous carcinoma of ductal origin (63%), but notably different from that of patients with carcinosarcoma (49%). Of 17 women with axillary node dissection, only two had metastases. Eleven women developed distant metastases, most commonly to the lungs. Metastasis present at or following initial surgery was an ominous sign, as all 11 women with metastases died from tumor. Size and microscopic circumscription were significant factors in predicting disease progression.
