Aberrant Endometrial DNA Methylome and Associated Gene Expression in Women with Endometriosis.

Endometriosis is an estrogen-dependent, progesterone-resistant disorder largely derived from retrograde transplantation of menstrual tissue/cells into the pelvis, eliciting an inflammatory response, pelvic pain, and infertility. Eutopic endometrium (within the uterus), giving rise to pelvic disease, displays cycle-dependent transcriptomic, proteomic, and signaling abnormalities, and although its DNA methylation profiles dynamically change across the cycle in healthy women, studies in endometriosis are limited. Herein, we investigated the DNA methylome and associated gene expression in three phases of the cycle in eutopic endometrium of women with severe endometriosis versus controls, matched for ethnicity, medications, smoking, and no recent contraceptive steroid use. Genome-wide DNA methylation and gene expression were coassessed in each sample. Cycle phase was determined by histology, serum hormone levels, and unsupervised principal component and hierarchical cluster analyses of microarray data. Altered endometrial DNA methylation in endometriosis was most prominent in the midsecretory phase (peak progesterone), with disruption of the normal pattern of cycle-dependent DNA methylation changes, including a bias toward methylation of CpG islands, suggesting wide-range abnormalities of the chromatin remodeling machinery in endometriosis. DNA methylation changes were associated with altered gene expression relevant to endometrial function/dysfunction, including cell proliferation, inflammation/immune response, angiogenesis, and steroid hormone response. The data provide insight into epigenetic reprogramming and steroid hormone actions in endometrium contributing to the pathogenesis and pathophysiology of endometriosis.

Psychological, social, and spiritual effects of contraceptive steroid hormones.

Governments and society have accepted and enthusiastically promoted contraception, especially contraceptive steroid hormones, as the means of assuring optimal timing and number of births, an undoubted health benefit, but they seldom advert to their limitations and side effects. This article reviews the literature on the psychological, social, and spiritual impact of contraceptive steroid use. While the widespread use of contraceptive steroid hormones has expanded life style and career choices for many women, their impact on the women's well-being, emotions, social relationships, and spirituality is seldom mentioned by advocates, and negative effects are often downplayed. When mentioned at all, depression and hypoactive sexual desire are usually treated symptomatically rather than discontinuing their most frequent pharmacological cause, the contraceptive. The rising incidence of premarital sex and cohabitation and decreased marriage rates parallel the use of contraceptive steroids as does decreased church attendance and/or reduced acceptance of Church teaching among Catholics. Lay summary: While there is wide, societal acceptance of hormonal contraceptives to space births, their physical side effects are often downplayed and their impact on emotions and life styles are largely unexamined. Coincidental to the use of "the pill" there has been an increase in depression, low sexual desire, "hook-ups," cohabitation, delay of marriage and childbearing, and among Catholics, decreased church attendance and reduced religious practice. Fertility is not a disease. Birth spacing can be achieved by natural means, and the many undesirable effects of contraception avoided.

Steroidal contraceptives: effect on bone fractures in women.

Steroidal contraceptive use has been associated with changes in bone mineral density in women. Whether such changes increase the risk of fractures later in life is not clear. Osteoporosis is a major public health concern. Age-related decline in bone mass increases the risk of fracture, especially of the spine, hip, and wrist. Concern about bone health influences the recommendation and use of these effective contraceptives globally. Our aim was to evaluate the effect of using hormonal contraceptives before menopause on the risk of fracture in women. Through April 2014, we searched for studies of fracture or bone health and hormonal contraceptives in MEDLINE, POPLINE, CENTRAL, EMBASE, and LILACS, as well as ClinicalTrials.gov and ICTRP. We examined reference lists of relevant articles for other trials. For the initial review, we wrote to investigators to find additional trials. Randomized controlled trials (RCTs) were considered if they examined fractures, bone mineral density (BMD), or bone turnover markers in women with hormonal contraceptive use prior to menopause. Eligible interventions included comparisons of a hormonal contraceptive with a placebo or with another hormonal contraceptive that differed in terms of drug, dosage, or regimen. They also included providing a supplement to one group. We assessed all titles and abstracts identified through the literature searches. Mean differences were computed using the inverse variance approach. For dichotomous outcomes, the Mantel-Haenszel odds ratio (OR) was calculated. Both included the 95% confidence interval (CI) and used a fixed-effect model. Due to differing interventions, no trials could be combined for meta-analysis. We applied principles from GRADE to assess the evidence quality and address confidence in the effect estimates. In addition, a sensitivity analysis included trials that provided sufficient data for this review and evidence of at least moderate quality. We found 19 RCTs that met our eligibility criteria. Eleven trials compared different combined oral contraceptives (COCs) or regimens of COCs; five examined an injectable versus another injectable, implant, or IUD; two studied implants, and one compared the transdermal patch versus the vaginal ring. No trial had fracture as an outcome. BMD was measured in 17 studies and 12 trials assessed biochemical markers of bone turnover. Depot medroxyprogesterone acetate (DMPA) was associated with decreased bone mineral density (BMD). The placebo-controlled trials showed BMD increases for DMPA plus estrogen supplement and decreases for DMPA plus placebo supplement. COCs did not appear to negatively affect BMD, and some formulations had more positive effects than others. However, no COC trial was placebo-controlled. Where studies showed differences between groups in bone turnover markers, the results were generally consistent with those for BMD. For implants, the single-rod etonogestrel group showed a greater BMD decrease versus the two-rod levonorgestrel group but results were not consistent across all implant comparisons.The sensitivity analysis included 11 trials providing evidence of moderate or high quality. Four trials involving DMPA showed some positive effects of an estrogen supplement on BMD, a negative effect of DMPA-subcutaneous on lumbar spine BMD, and a negative effect of DMPA on a bone formation marker. Of the three COC trials, one had a BMD decrease for the group with gestodene plus EE 15 μg. Another indicated less bone resorption in the group with gestodene plus EE 30 μg versus EE 20 μg. Whether steroidal contraceptives influence fracture risk cannot be determined from existing information. The evidence quality was considered moderate overall, largely due to the trials of DMPA, implants, and the patch versus ring. The COC evidence varied in quality but was low overall. Many trials had small numbers of participants and some had large losses. Health care providers and women should consider the costs and benefits of these effective contraceptives. For example, injectable contraceptives and implants provide effective, long-term birth control yet do not involve a daily regimen. Progestin-only contraceptives are considered appropriate for women who should avoid estrogen due to medical conditions.

Progestin-only contraception prevents bone loss in postpartum breastfeeding women

BackgroundThere are an increase in bone loss during the first 6 months postpartum and a complete recovery postweaning. A few studies of steroid contraceptive use during this period provide some evidence towards protection of bone loss with progestin-only contraceptive methods. ObjectiveThe study was conducted to evaluate forearm bone mineral density (BMD) of breastfeeding postpartum women using nonhormonal and progestin-only contraceptive methods. Study DesignA prospective cohort study of postpartum women had an analysis performed at 6 months postpartum correlating BMD with contraceptive use. Forearm BMD was measured 7–10 days, 3 months and 6 months postpartum. Eighty-two women were analyzed, comparing nonhormonal (54) and progestin-only (28) contraceptive methods. Information about breastfeeding duration, amenorrhea and body mass index was collected. ResultsBaseline characteristics of the study population showed no statistical differences between the groups. The median duration of breastfeeding for both groups was 183 days. A significant BMD decrease was observed for the nonhormonal group (p<.001); however, no statistical difference was detected for the progestin-only group. Body mass index, BMD at 7–10 days postpartum and total duration of breastfeeding were positively correlated with BMD at 6 months. ConclusionsOur findings suggest a preventive effect towards postpartum bone loss with progestin-only contraception in breastfeeding women.

129 Molecular diagnosis of pancreatic cancer using a combination of genetic and epigenetic markers

To determine whether the long-acting injectable progestational contraceptive DMPA, depot-medroxyprogesterone acetate, alters the risk of breast cancer in women, a hospital-based case-control study was conducted in five participating hospitals in Nairobi, Kenya, Mexico City, Mexico, Bangkok, Thailand (two hospitals), and Chiang Mai, Thailand. 869 women with newly diagnosed breast cancer who were young enough to have used DMPA for contraception, and 11 890 women of similar age who had been admitted to hospital for conditions unrelated to steroid contraceptive use, were interviewed to obtain information about previous use of steroid contraceptives and suspected risk factors for breast cancer. DMPA had been used by 12·5% of cases and 12·2% of controls. Relative risk (95% Cl) in women who had ever used DMPA was 1·21 (0·96, 1·52). Risk was increased within the first 4 years of initial exposure, mainly in women under 35 years. This observation did not seem to result from selective surveillance for breast cancer in DMPA users. Risk did not increase with duration of use, and was not increased in women who had started to use DMPA more than 5 years previously. These results provide reassurance that women who have used DMPA for a long time and who initiated use many years previously are not at increased risk of breast cancer.

Extra‐tumoral breast tissue in breast cancer patients: Variations with steroid contraceptive use

The association between oral contraceptive (OC) use and benign breast changes in extra-tumoral breast tissue was studied histologically in 1,503 breast cancer patients from The WHO Collaborative Study of Neoplasia and Steroid Contraceptives. The occurrence of ductal hyperplasia, ductal atypia, sclerosing adenosis, cysts, apocrine metaplasia, apocrine hyperplasia, apocrine atypia, adenosis, lobular atypia, duct ectasia, calcifications, inflammatory reaction, lactational metaplasia and a high epithelial-stromal ratio was graded semi-quantitatively. Prevalence odds ratio (POR) for each histologic variable was calculated by logistic regression analyses. Patients who had ever used OC had lower occurrence of ductal hyperplasia than never users (POR 0.72 (95% CI 0.52-0.99)). Current use and more than 8 years of use was also associated with a lower prevalence of ductal hyperplasia (POR 0.40 (0.20-0.81) and POR 0.33 (0.17-0.64), respectively). Age > 35 years at first use was associated with increased prevalence of ductal carcinoma in situ (POR 2.15 (1.05-4.40)), but not of atypical ductal hyperplasia. Our results show that the effects of OC use on ductal hyperplasia in non-neoplastic breast tissue of breast cancer patients are similar to what others have found in patients with benign breast disease only. The increased prevalence of extra-tumoral ductal carcinoma in situ in breast cancer patients who started OC use at high age may possibly be explained by a longer preinvasive phase in these patients.

The role of steroid contraceptive hormones in the pathogenesis of invasive cervical cancer: a review.

Invasive cervical cancer remains a leading cause of morbidity and mortality, especially among women in the developing world where screening is either deficient or absent. Of all agents linked to the causation of this disease, high-risk human papillomavirus (HPV) appears to be the strongest factor. However, not all women with HPV develop cervical cancer. Steroid contraception has been postulated to be one mechanism whereby HPV exerts its tumorigenic effect on cervical tissue. Steroids are thought to bind to specific DNA sequences within transcriptional regulatory regions on the HPV DNA to either increase or suppress transcription of various genes. Although some earlier studies were reassuring as no increased incidence of cervical cancer was observed, subsequent research has shown a causative association, especially among long-term users. The role of steroids was further enhanced by the discovery of hormone receptors in cervical tissue. Some earlier studies of oral contraceptive steroids found no increased risk, even after controlling for other risk factors, including smoking and number of partners. However, prospective studies have shown a greater progression of dysplasia to carcinoma-in-situ with more than 6 years of oral steroid contraceptive use. Similar findings were also evident from other work, including the Royal College of General Practitioners Oral Contraception Study. The WHO Collaborative Study of Neoplasia and Steroid Contraceptives showed a relative risk of 1.2 for invasive cancer in users of the long-acting progestational contraceptive, depo-medroxyprogesterone acetate. However, in users of more than 5 years duration, an estimate of 2.4 was reported. The upstream regulatory region (URR) of the HPV type 16 viral genome, mediates transcriptional control of the HPV genome and is thought to contain enhancer elements that are activated by steroid hormones. It has been shown that steroid hormones bind to specific glucorticoid-response elements within HPV-DNA. Experimental evidence has revealed that high-risk type HPV 16 are able to stimulate the development of vaginal and cervical squamous cell carcinomas in transgenic mice exposed to slow-release pellets of 17 beta-estradiol in the presence of human keratin-14 promoter. Squamous cell carcinomas developed in a multi-stage pathway only in transgenic mice and not in nontransgenic mice. The E6 oncoprotein of HPV 16 has been shown to bind to the p53 tumor suppressor gene and stimulate its degradation by a ubiquitin-dependent protease system. Steroid hormones are thought to increase the expression of the E6 and E7 HPV 16 oncogenes, which in turn bind to and degrade the p53 gene product, leading to apoptotic failure and carcinogenesis. However, the molecular basis of this remains to be proven.

Effects of Inhaled Glucocorticoids on Bone Density in Premenopausal Women

Many asthmatics today are treated with inhaled glucocorticoids. Oral steroids are known to accelerate bone loss and promote fracture, but it is not clear that the inhalational route has similar consequences; past studies have given inconsistent results. For this reason a 3-year prospective cohort study was performed in 109 premenopausal women 18 to 45 years of age who had asthma but no condition that causes bone loss. The participants had inhaled four or more puffs daily of glucocorticoid in the same dose for at least 6 weeks. All those not receiving triamcinolone acetonide were switched to this corticoid in a dose of 100 μg per puff. Bone density was measured by dual-photon absorptiometry at intervals for up to 3 years. Patients used a maximum of 28 puffs per day of inhaled glucocortoid. The average number of daily puffs correlated negatively with the yearly change in bone density, as measured both in the total hip and the trochanter. Each additional daily puff correlated with a yearly decline in bone density of 0.00044 g/cm 2 at these sites. There was, however, no significant association with declining bone density at the femoral neck and spine. The relation between bone density at the total hip and trochanter and the average daily puffs of inhaled steroid persisted after adjusting for the use of oral or parenteral glucocorticoids, concurrent use of nasal steroid, age, and oral contraceptive use. Neither the dose of inhaled glucocorticoid nor the decline in bone density correlated with urinary levels of N-telopeptide, calcium, or cortisol, or with serum levels of osteocalcin, calcium, cortisol, or parathyroid hormone. Higher inhaled doses of glucocorticoid correlated directly with small annual declines in bone density in the total hip and trochanter in these premenopausal women treated for asthma. This finding suggests using the lowest dose needed to control asthmatic symptoms. Periodic bone density measurements could indicate when prophylactic measures to protect skeletal integrity are appropriate.

Benign and Solid Tumors of the Liver: Relationship to Sex, Age, Size of Tumors, and Outcome

From 1983 through 1997, our center diagnosed 130 cases of benign neoplasms: 27 with focal nodular hyperplasia (FNH), 25 with hepatic adenoma, 71 with cavernous hemangioma, and seven with mixed tumors of different diagnoses. Most often these lesions were seen in females [female-to-male ratio (f/m): 5.5/1]. Hepatic adenomas and mixed tumors were seen exclusively in females and FNH predominantly in females (f/m: 26/1). Hemangiomas, however, were not uncommon in men (f/m: 52/19) relative to the other tumors (P < 0.001). Furthermore patients with hemangioma were older (mean age: 49 years) whereas patients with hepatic adenoma, FNH, and mixed tumors were often younger (mean age: 33, 35, and 44 years respectively; P < 0.004). Oral contraceptive steroid use was related by 21 of 25 patients (84%) with hepatic adenoma, 22 of 26 (85%) females with FNH, five of seven (71%) females with mixed tumors, and 10 of 52 (19%) patients with hemangioma. Ninety-five of the 130 patients (73%) had one or more symptoms. There was no statistically significant correlation between symptoms and the size of the lesion, the final diagnosis, and whether there were solitary or multiple masses. Three of 25 (12%) with hepatic adenoma presented with rupture, and one of 27 (4%) with FNH had such a consequence. None of the hemangiomas presented with rupture or progressed to such a state. One patient with hepatic adenoma (4%) had a focus of malignancy. Surgical removal of benign tumors was performed in 82 of 130 patients (63%), and there was one operative mortality (1.2%) in a patient who had a caudate lobe FNH. The types of surgical procedures included segmentectomy (62%), lobectomy (34%), and trisegmentectomy (4%). In two of 84 patients who had undergone laparotomy resection was not technically possible. Resection is recommended in all cases of hepatic adenoma because of fear of rupture or associated focus of malignancy. FNH was not observed to undergo a malignant transformation and will rarely rupture. Surgery is only recommended for symptomatic hemangioma, and size of the lesion is not a criterion for excision.

Ovarian steroid and cytokine modulation of human endometrial angiogenesis.

A key mechanism underlying the cyclical growth of the endometrium is its ability to regenerate a vascular capillary network. In normal cycling human endometrium, angiogenesis is influenced by both endocrine and paracrine factors. Hormonal manipulation of the endometrium, such as that occurring during the use of steroidal contraception, appears to result in capillary proliferation and fragility. As a consequence of these vascular changes, contraceptive users may be predisposed to unpredictable uterine bleeding, which is responsible for the high frequency of contraceptive discontinuation. In this paper we address mechanisms responsible for vascular endothelial cell proliferation in normal and contraceptive steroid-exposed endometria. We propose that regulation of endometrial angiogenesis is mediated indirectly, via steroid and cytokine actions on vascular endothelial growth factor (VEGF), and we present data indicating that VEGF expression in normal endometrial stromal cells is increased by oestrogens and progestins. Three proinflammatory cytokines with angiogenic effects in other systems (i.e. interleukin-1beta, tumour necrosis factor-alpha and interferon-gamma) do not appear to up-regulate VEGF expression in normal endometrial stromal cells. Well-characterized in-vitro models in conjunction with immunohistochemistry provide useful experimental systems to study endometrial neovascularization under physiological conditions and in those potentially perturbed via the use of contraceptive steroids.

Safety of hormonal steroid contraceptive use for hepatitis B virus carrier women

To investigate the relationship between hormonal steroid contraception and liver function in HBsAg positive women, 159 HBsAg positive women with normal liver function and negative anti-HBc-IgM are collected for a non-randomized comparative trial, 78 in low dose combined OC group and 81 in control group. Follow up observations will be at three and six months after admission. During the observation, no significant differences between two groups are found including serum GPT, albumin, serum bilirubin and prothrombin time. However in the OC group, there is one case who has had a transient moderate abnormal SGPT. No any hepatitis manifestations are found in both groups. The current primary study supports the safety of low dose OCs in HBsAg positive women. However, additional investigations in larger sample are needed. Copyright (c) 2000 John Wiley & Sons, Ltd.

The pharmacokinetics of oxybutynin is unaffected by gender and contraceptive steroids.

The effect of gender and concomitant use of contraceptive steroids on the absorption and metabolism of oxybutynin was investigated in 49 healthy volunteers, 24 females and 25 males. Serum concentrations of oxybutynin and its active metabolite, N-desethyloxybutynin, were measured for up to 48 h after ingestion of a single dose of 10 mg oxybutynin. Intake of oral contraceptive steroids had no significant effect on the pharmacokinetic parameters of oxybutynin or its metabolite. Both in males and females, the mean area under the curve (AUC0-t) of N-desethyloxybutynin was about 13 times higher and the peak concentration (Cmax) 15 to 19 times higher than the AUC0-t and Cmax of the parent oxybutynin, with no significant differences between males and females. The pharmacokinetics of orally administered oxybutynin shows a considerable interindividual variability, but is unaffected by gender and use of contraceptive steroids.

Carbohydrate-deficient transferrin in healthy women: relation to estrogens and iron status.

The determination of carbohydrate-deficient transferrin (CDT) in serum has been found useful as a marker of increased alcohol consumption of > 60 g/day. It is not clear why the reference range is different for women (0 to 26 units/liter) and men (0 to 20 units/liter). We evaluated serum CDT in 286 healthy subjects (209 women, 77 men) using a commercially available radioimmunoassay. Premenopausal women had higher CDT levels than postmenopausal women, whereas no age-related difference of CDT levels was found in men. In postmenopausal women, higher CDT levels were associated with estrogen replacement therapy. In premenopausal women, however, neither the phase of the menstrual cycle nor contraceptive steroid use showed a significant association with the increase in CDT levels. No significant correlations were found between CDT and either serum estradiol or serum iron. In conclusion, both premenopausal state and postmenopausal estrogen replacement therapy seem to increase serum levels of CDT. Therefore, menopausal status and exogenous estrogens should be considered when interpreting CDT values in women.

Steroidal contraceptive use update, United States, 1989-1994.

To update United States steroidal contraceptive use data for the period 1989 to 1994. Pharmaceutical marketing data were used to examine trends in the utilization and distribution of oral contraceptives, Norplant, and Depo-Provera. There were 56.8 million prescriptions for oral contraceptives dispensed through retail pharmacies in 1994. Estrogen and progestin doses remained fairly stable over time. The average ethinyl estradiol dose of formulations was approximately 34 microg per pill. Mentions for oral contraceptives among 35- to 44-year-old women increased. Approximately 169,000 Norplant systems were distributed from 1991 through 1994. More than 1.5 million milliliters of Depo-Provera were distributed from 1993 to 1994. Oral contraceptives remain a popular form of contraception. Parenteral formulations have been rapidly accepted.

Primary infertility and oral contraceptive steroid use

To determine the association between combined monophasic oral contraceptive (OC) use and primary infertility. Case-control. Women serving as controls of the Cancer and Steroid Hormone Study. Women were 19 to 40 years of age at first conception or infertility diagnosis. Based on 24 consecutive months of unprotected intercourse without a recognized conception, 419 nulligravid women had primary infertility; controls were 2,120 fertile women. A calendar of each woman’s reproductive history was used to determine fertility status and contraceptive use before infertility diagnosis or first conception. Primary infertility. Combined monophasic OC use was associated with a lower frequency of primary infertility, particularly among younger (age 20 years) compared with older women (age 30 years) after adjusting for barrier method use and education. A similar association was found for duration of OC use. When adjusted for age at first conception or infertility and barrier method, both higher (> 50 μ g) and lower (≤ 550 μ g) estrogen dose use were associated with decreased risk of primary infertility. Combined monophasic OC use was associated with a lower frequency of primary infertility.

Benign hepatic tumors: focal nodular hyperplasia and hepatocellular adenoma.

Focal nodular hyperplasia (FNH) and hepatocellular adenoma (HA) are uncommon benign hepatic tumors that continue to pose diagnostic and therapeutic challenges. An update of a recent Mayo Clinic experience is presented to highlight the management of patients harboring these neoplasms. A marked female predominance was seen. Incidental diagnosis was more prevalent with FNH, whereas symptomatic presentation was typical of HA. The frequency of oral contraceptive steroid use was similar regardless of tumor histology. Preoperative diagnosis remains difficult. Scintigraphy proved most specific, and ultrasonography and computed tomography were equally sensitive. Resection was employed in most patients. There was no mortality and minimal morbidity. Selective observation of FNH was uneventful, but resolution of HA after abstinence of oral contraceptive steroids was uncommon. These findings and data from the literature support selective management of benign liver tumors.

Breast cancer and depot-medroxyprogesterone acetate: a multinational study: WHO COLLABORATIVE STUDY OF NEOPLASIA AND STEROID CONTRACEPTIVES

To determine whether the long-acting injectable progestational contraceptive DMPA, depot-medroxyprogesterone acetate, alters the risk of breast cancer in women, a hospital-based case-control study was conducted in five participating hospitals in Nairobi, Kenya, Mexico City, Mexico, Bangkok, Thailand (two hospitals), and Chiang Mai, Thailand. 869 women with newly diagnosed breast cancer who were young enough to have used DMPA for contraception, and 11 890 women of similar age who had been admitted to hospital for conditions unrelated to steroid contraceptive use, were interviewed to obtain information about previous use of steroid contraceptives and suspected risk factors for breast cancer. DMPA had been used by 12·5% of cases and 12·2% of controls. Relative risk (95% Cl) in women who had ever used DMPA was 1·21 (0·96, 1·52). Risk was increased within the first 4 years of initial exposure, mainly in women under 35 years. This observation did not seem to result from selective surveillance for breast cancer in DMPA users. Risk did not increase with duration of use, and was not increased in women who had started to use DMPA more than 5 years previously. These results provide reassurance that women who have used DMPA for a long time and who initiated use many years previously are not at increased risk of breast cancer.

Contraceptive steroids as a risk factor for hepatocellular carcinoma: A case/control study in south african black women

The role of contraceptive steroids in the etiology or pathogenesis of hepatocellular carcinoma in urban South African black women was investigated in a hospital-based case and control study. Participating were 46 women, 19 to 54 yr old, with carcinoma, and 92 matched controls. South African blacks have a high incidence of hepatocellular carcinoma, and urban black women have used contraceptive steroids fairly widely for a number of years. Use of contraceptive steroids for longer than 6 mo (mean duration 46.7 mo) was not found to pose a risk for development of hepatocellular carcinoma in this population--relative risk 0.8 (95% confidence interval [C.I.] 0.4 to 1.7). This was also true of use for longer than 8 yr--relative risk 0.6 (95% C.I. 0.2 to 2.5), and if a combination of an estrogen and a progestogen or a progestogen alone was used (relative risk 1.7 [95% C.I. 0.7 to 4.2] and 0.4 [95% C.I. 0.1 to 1.2], respectively). Chronic hepatitis B virus infection was confirmed to have an etiological association with hepatocellular carcinoma, but there was no evidence that contraceptive steroids acted as a co-carcinogen with the virus or, conversely, that they played a causal role in patients negative for hepatitis B surface antigenemia. We cannot, however, exclude the possibility that contraceptive steroids may play a causal role in hepatocellular carcinoma in black women who have never been infected with the hepatitis B virus. Nor was there evidence that contraceptive steroids acted in concert with either cigarette smoking or chronic alcohol abuse in hepatocarcinogenesis.(ABSTRACT TRUNCATED AT 250 WORDS)
