Abstract

Background/Aim: Insulin-like growth factors (IGFs) and IGF binding proteins (IGFBPs) play a role in the normal development of breast tissue, and possibly in breast cancer aetiology. IGFBP2, one of six members of the IGFBP superfamily, acts as regulator of the IGFs and has pleiotropic effects in normal and neoplastic tissues. Because IGFs have mitogenic effects on mammary epithelia, this study investigated IGFBP2 expression in mammary tissues of different benign and malignant entities. Methods: Immunohistochemistry was used to study correlations between the presence and intensity of IGFBP2 staining and tumour type and grade, in addition to steroid hormone receptor status, in 120 breast specimens. Expression was measured by quantitative colour video image analysis and semiquantitative evaluation, and the measurements correlated well ( r = 0.92; p Results: Both methods found no significant expression of IGFBP2 in normal glandular cells and hyperplasia (group I). Atypical hyperplasia showed a slightly increased cytoplasmic expression of IGFBP2, and carcinoma in situ showed a distinctive, membrane associated and cytoplasmic expression (group II). Infiltrating carcinomas strongly expressed cytoplasmic IGFBP2 (group III). There were significant differences between group I and II, and between group II and III. There were no significant differences between invasive lobular and invasive ductal carcinoma, or between grades I, II, and III within these entities. There was no significant correlation between IGFBP2 immunostaining and oestrogen or progesterone receptor positivity within the malignant group. Conclusions: IGFBP2 mitogenic signals of autocrine/paracrine regulatory mechanisms may be responsible for the growth of breast carcinomas and IGFBP2 may be an independent indicator of malignancy.

Analyses included 58,515 women with invasive breast cancer and 95,067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19-1.45, P/=45 g per day alcohol.

Abstract

Background Menarche and menopause mark the onset and cessation, respectively, of ovarian activity associated with reproduction, and affect breast cancer risk. Our aim was to assess the strengths of their effects and determine whether they depend on characteristics of the tumours or the affected women.Methods Individual data from 117 epidemiological studies, including 118 964 women with invasive breast cancer and 306 091 without the disease, none of whom had used menopausal hormone therapy, were included in the analyses. We calculated adjusted relative risks (RRs) associated with menarche and menopause for breast cancer overall, and by tumour histology and by oestrogen receptor expression.Findings Breast cancer risk increased by a factor of 1.050 (95% CI 1.044-1.057; p < 0.0001) for every year younger at menarche, and independently by a smaller amount (1.029, 1.025-1.032; p < 0.0001), for every year older at menopause. Premenopausal women had a greater risk of breast cancer than postmenopausal women of an identical age (RR at age 45-54 years 1.43, 1.33-1.52, p < 0.001). All three of these associations were attenuated by increasing adiposity among postmenopausal women, but did not vary materially by women's year of birth, ethnic origin, childbearing history, smoking, alcohol consumption, or hormonal contraceptive use. All three associations were stronger for lobular than for ductal tumours (p < 0.006 for each comparison). The effect of menopause in women of an identical age and trends by age at menopause were stronger for oestrogen receptor-positive disease than for oestrogen receptor-negative disease (p < 0.01 for both comparisons).Interpretation The effects of menarche and menopause on breast cancer risk might not be acting merely by lengthening women's total number of reproductive years. Endogenous ovarian hormones are more relevant for oestrogen receptor-positive disease than for oestrogen receptor-negative disease and for lobular than for ductal tumours.Funding Cancer Research UK.

Abstract

Background Menarche and menopause mark the onset and cessation, respectively, of ovarian activity associated with reproduction, and affect breast cancer risk. Our aim was to assess the strengths of their effects and determine whether they depend on characteristics of the tumours or the affected women. Methods Individual data from 117 epidemiological studies, including 118 964 women with invasive breast cancer and 306 091 without the disease, none of whom had used menopausal hormone therapy, were included in the analyses. We calculated adjusted relative risks (RRs) associated with menarche and menopause for breast cancer overall, and by tumour histology and by oestrogen receptor expression. Findings Breast cancer risk increased by a factor of 1.050 (95% CI 1.044-1.057; p < 0.0001) for every year younger at menarche, and independently by a smaller amount (1.029, 1.025-1.032; p < 0.0001), for every year older at menopause. Premenopausal women had a greater risk of breast cancer than postmenopausal women of an identical age (RR at age 45-54 years 1.43, 1.33-1.52, p < 0.001). All three of these associations were attenuated by increasing adiposity among postmenopausal women, but did not vary materially by women’s year of birth, ethnic origin, childbearing history, smoking, alcohol consumption, or hormonal contraceptive use. All three associations were stronger for lobular than for ductal tumours (p < 0.006 for each comparison). The effect of menopause in women of an identical age and trends by age at menopause were stronger for oestrogen receptor-positive disease than for oestrogen receptor-negative disease (p < 0.01 for both comparisons). Interpretation The effects of menarche and menopause on breast cancer risk might not be acting merely by lengthening women’s total number of reproductive years. Endogenous ovarian hormones are more relevant for oestrogen receptor-positive disease than for oestrogen receptor-negative disease and for lobular than for ductal tumours.

Abstract

The main subject of this hospital-based case-control study was the possible relationship between use of combined oral contraceptives (OCs) containing chlormadinone acetate and breast cancer. Analyses were based on data from 490 cases with newly diagnosed breast cancer and 1,223 controls and were separately performed for combined OCs with and without chlormadinone. For either of the combined OCs, risk was not elevated in ever users, did not increase with duration of use and did not change with time since initial exposure or with time since most recent use. However, the relative risk was increased in current users: RR = 1.72 (0.88, 3.36) for combined OCs with chlormadinone and RR = 1.42 (1.01, 2.00) for combined OCs without chlormadinone, which is, however, explained as a screening effect. These results show that chlormadinone as a constituent of combined OCs does not influence breast cancer risk.The main subject of this hospital-based case-control study was the potential relationship between use of combined oral contraceptives (OCs) containing chlormadinone acetate (CA) and breast cancer. Analyses were performed for combined OCs with and without CA. For either of the combined OCs, risk was not elevated in ever users, it did not increase with the duration of use, and it did not change with time since the initial exposure or with time since most recent use. However, the relative risk was increased in current users---RR=1.72 (0.88, 3.36) for combined OCs with CA and RR=1.42 (1.01, 2.00) for combined OCs without CA which is explained as a screening effect. These results demonstrate that CA as a constituent of combined OCs does not influence breast cancer risk.

Abstract

Background The Collaborative Group on Hormonal Factors in Breast Cancer has brought together and reanalysed the worldwide epidemiological evidence on the relation between breast cancer risk and use of hormonal contraceptives. Methods Individual data on 53297 women with breast cancer and 100 239 women without breast cancer from 54 studies conducted in 25 countries were collected, checked, and analysed centrally. Estimates of the relative risk for breast cancer were obtained by a modification of the Mantel-Haenszel method. All analyses were stratified by study, age at diagnosis, parity, and, where appropriate, the age a woman was when her first child was born, and the age she was when her risk of conception ceased. Findings The results provide strong evidence for two main conclusions. First, while women are taking combined oral contraceptives and in the 10 years after stopping there is a small increase in the relative risk of having breast cancer diagnosed (relative risk [95% CI] in current users 1.24 [1.15-1.33], 2p

Abstract

The Collaborative Group on Hormonal Factors in Breast Cancer has brought together and reanalysed the worldwide epidemiological evidence on breast cancer risk and use oi hormonal contraceptives. Original data from 54 studies, representing about 90% of the information available on the topic, were collected, checked and analysed centrally. The 54 studies were performed in 26 countries and include a total of 53,297 women with breast cancer and 100,239 women without breast cancer. The studies were varied in their design, setting and timing. Most information came from case-control studies with controls chosen from the general population; most women resided in Europe or North America and most cancers were diagnosed during the 1980s. Overall 41% of the women with breast cancer and 40% of the women without breast cancer had used oral contraceptives at some time: the median age at first use was 26 years, the median duration of use was 3 years, the median year of first use was 1968, the median time since first use was 16 years, and the median time since last use was 9 years. The main findings, summarised elsewhere,I are that there is a small increase in the risk of having breast cancer diagnosed in current users of combined oral contraceptives and in women who had stopped use in the past 10 years but that there is no evidence of an increase in the risk more than 10 years after stopping use. In addition, the cancers diagnosed in women who had used oral contraceptives tended to be less advanced clinically than the cancers diagnosed in women who had not used them. Despite the large number of possibilities investigated, few factors appeared to modify the main findings either in recent or in past users. For recent users who began use before age 20 the relative risks are higher than for recent users who began at older ages. For women whose use of oral contraceptives ceased more than 10 years before there was some suggestion of a reduction in breast cancer risk in certain subgroups, with a deficit of tumors that had spread beyond the breast, especially among women who had used preparations containing the highest doses of oestrogen and progestogen. These findings are unexpected and need to be confirmed. Although these data represent most of the epidemiologi cal evidence on the topic to date, there is still insufficient information to comment reliably about the effects of specific types of oestrogen or of progestogen. What evidence there is suggests, however, no major differences in the effects for specific types of oestrogen or of progestogen and that the pattern of risk associated with use of hormonal contraceptives containing progestogens alone may be similar to that observed for preparations containing both oestrogens and progestogens. On the basis of these results, there is little difference between women who have and have not used combined oral contraceptives in terms of the estimated cumulative number of breast cancers diagnosed during the period from starting use up to 20 rears after stopping. The cancers diagnosed in women who have used oral contraceptives are, however, less advanced clinically than the cancers diag nosed in never users. Further research is needed to establish whether the associations described here are due to earlier diagnosis of breast cancer in women who have used oral contraceptives, to the biological effects of the hormonal contraceptives or to a combination of both. Little information is as yet available about the effects on breast cancer risk of oral contraceptive use that ceased more than 20 years before and as such data accumulate it will be necessary to reexamine the worldwide evidence.

Abstract

Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58515 women with invasive breast cancer and 95067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women’s age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19 - 1.45, P < 0.00001) for an intake of 35 - 44 g per day alcohol, and 1.46 (1.33 - 1.61, P < 0.00001) for greater than or equal to 45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P

Abstract

This study was conducted to identify reproductive and dietary factors associated with benign proliferative mammary epithelial cell changes. Subjects were women enrolled in a randomized trial of breast self-examination in Shanghai, China. Women who developed fibrocystic breast conditions classified as nonproliferative (175 women), proliferative (181 women), or proliferative with atypia (33 women) between 1995 and 2000 and 1,070 unaffected trial participants were administered general risk factor and food frequency questionnaires. Conditional logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals. High parity and consumption of fresh fruits and vegetables were more strongly associated with a reduced risk of proliferative and atypical lesions than with nonproliferative conditions. For the fourth quartile of consumption versus the first, odds ratios for lesions diagnosed as nonproliferative, proliferative, and proliferative with atypia were 0.4 (95% confidence interval (CI): 0.2, 0.7), 0.2 (95% CI: 0.1, 0.4), and 0.1 (95% CI: 0.03, 0.5), respectively, for fruit intake and 0.6 (95% CI: 0.3, 1.1), 0.4 (95% CI: 0.2, 0.7), and 0.1 (95% CI: 0.1, 0.9), respectively, for vegetable intake. Reduced but nonsignificant risks in relation to soy products were observed for proliferative and atypical lesions. No single nutrient or botanical family was appreciably more strongly associated with proliferative conditions than with nonproliferative conditions, after results were controlled for total fruit and vegetable consumption. A diet rich in fruits and vegetables may reduce cellular proliferation in the mammary epithelium; this is one mechanism by which such a diet could reduce risk of breast cancer.

Abstract

Background: The aim of this study was to examine, in a population not submitted to mass screening, the risk of cancer and cervical intra-epithelial neoplasia (CIN) in Pap smears from women without previously reported positive smears.Methods: In a logistic regression model consisting of 58,271 smears from 40,536 Norwegian women the risk of cytologically indicated CIN was studied according to age and time elapsed since last smear.Results: The risk of CIN was highest in smears from women with no previously registered smears and in smears taken after an interval of > or = 5 years. Odds ratio for CIN I-II adjusted for age was highest in first time smears and in smears taken after an interval of 5 years. Odds ratio for CIN III was highest in first registered smears. No difference in risk of CIN III was found in smears taken within one year or 2-3 years after the last smear. The increased risk of CIN III in first smears was most pronounced in postmenopausal women ( > 50 years). Nine of 16 cases with cytological indication of cancer were found in women having a smear taken for the first time. All cases with malignancy in smears were > 50 years.Conclusions: The risk of cytologically diagnosed premalignant cervical conditions increases with time since the previous smear, but more than 5 years have to elapse before the risk is comparable with that in first smears taken. Postmenopausal women without previous smears run the highest risk of serious cervical premalignancies and cancer. [ABSTRACT FROM AUTHOR]

Abstract

A 49 year old man presented with severe cyanosis and dyspnoea on exercise. Clinical examination together with echocardiography, cardiac catheterisation, and angiography showed a balloting tumour in the right atrium, intermittently occluding the tricuspid ostium, and an atrial right to left shunt. At operation a pedunculated vascular tumour was found with a broad base which was embedded in the atrial wall and continued into the interventricular septum. Histological examination showed angiosarcomatous features and signs of a less than radical excision. The patient, who made an uneventful recovery, was given postoperative radiotherapy. After 36 months there are no signs of recurrence or metastasis. [ABSTRACT FROM PUBLISHER]

30. Diverticular disease of the large intestine in Northern Norway.

Eide, T J and Stalsberg, H

Abstract

In 280 unselected necropsies on patients over 20 years of age in Northern Norway, diverticular disease was present in 25% of the males and 43% of the females. The frequency of diverticular disease increased in both sexes by age. Both the frequency of diverticular disease and the average number of diverticula per case with diverticular disease were higher in females than in males in all age groups. The sigmoid was the most frequent site of diverticula in both sexes and for all ages, and the average number of diverticula per diverticulum-bearing segment was also highest in the sigmoid for all ages and in both sexes. The average number of diverticula in the sigmoid of affected individuals increased with age and with the number of segments involved. Diverticular disease was not associated with adenomas of the large intestine or with malignant or benign neoplasms elsewhere in the body or with any of the common diseases thought to be related to a Western type of diet, except with cerebrovascular disease.

Abstract

Data from a population-based case-control study of breast cancer in men were used to examine the hypothesis that occupational exposure to electromagnetic fields increases the risk of breast cancer. Incident cases (n = 227) diagnosed between 1983 and 1987 were obtained from 10 population-based cancer registries of the Surveillance, Epidemiology, and End Results program of the National Cancer Institute. Controls (n = 300) were selected by random digit dialing and from Medicare eligibility lists. Exposure status, defined as ever having been employed in a job which has been classified as involving potential exposure to electromagnetic fields, was assigned without knowledge of case/control status. An elevated risk was found for any job with exposure (odds ratio (OR) = 1.8, 95 percent confidence interval (CI) 1.0-3.7), and risk was highest among electricians, telephone linemen, and electric power workers (OR = 6.0, 95 percent CI 1.7-21) and radio and communications workers (OR = 2.9, 95 percent CI 0.8-10). Risk did not vary with duration of exposed employment. The risk was highest among subjects who were first employed in jobs with exposure before the age of 30 years and who were initially exposed at least 30 years prior to diagnosis. These results lend support to the theory that electromagnetic fields may be related to breast cancer in men. The hypothesis warrants evaluation in women.

36. Cigarette smoking and the incidence of cervical intraepithelial neoplasia, grade III, and cancer of the cervix uteri.

Author

Gram, I T, Austin, H, and Stalsberg, H

Abstract

The relation between cigarette smoking and cervical intraepithelial neoplasia, grade III (CIN III), and cervical cancer was examined among a cohort of 6,812 women in Tromsö, Norway, between 1980 and 1989. During the 52,844 person-years of observation, 185 incident cases (177 women with CIN III and eight with cervical cancer) were recorded in the regional pathology registry. The age-adjusted incidence rates of CIN III and cervical cancer were 267/100,000 person-years among women who had never smoked, 183/100,000 person-years among exsmokers, and 476/100,000 person-years among current smokers. A multivariate model containing terms for age, marital status, and frequency of intoxication yielded a relative rate for current smokers compared with nonsmokers of 1.5 (95% confidence interval 1.0-2.2). Statistical trend tests for the number of cigarettes smoked per day (never, 1-14, and greater than or equal to 15 cigarettes), years of smoking (never, 1-9, and greater than or equal to 10 years), and age started smoking (less than 16, 16-18, 19-21, and greater than or equal to 22 years) all yielded significant results. These findings support the opinion that CIN III and cervical cancer are a smoking-related disease.

37. Breast cancer in men: risk factors with hormonal implications.

Author

Thomas, D B, Jimenez, L M, McTiernan, A, Rosenblatt, K, Stalsberg, H, Stemhagen, A, Thompson, W D, Curnen, M G, Satariano, W, and Austin, D F

Abstract

Cases included in a population-based case-control study of breast cancer in men were recruited from 10 geographic areas of the United States from 1983 to 1986. Controls, matched to cases on age and geographic area, were selected by random digit dialing for men under age 65 years and from Health Care Financing Administration files for older men. Results are based on responses from 227 cases and 300 controls to questions asked in a standardized personal interview. An increased risk of breast cancer was most strongly associated with undescended testes and was also related to orchiectomy, orchitis, testicular injury, late puberty, and infertility; and a decreasing trend in risk was observed with an increasing number of children. Relative risk estimates were also elevated in relation to a history of high blood cholesterol, rapid weight gain, benign breast conditions, and possibly obesity. These findings suggest that breast cancer in men develops in response to androgen deficiency associated with testicular dysfunction and under conditions associated with excess estrogen. Risk was also found to be elevated in men with a history of amphetamine use, diabetes, and cigar smoking and reduced in men with prior head trauma.

Abstract

Context: - Pathology services are poorly developed in Sub-Saharan Africa. Komfo Anokye Teaching Hospital in Kumasi, Ghana, asked for help from the pathology department of the University Hospital of North Norway, Tromsø., Objective: - To reestablish surgical pathology and cytology in an African pathology department in which these functions had ceased completely, and to develop the department into a self-supporting unit of good international standard and with the capacity to train new pathologists., Design: - Medical technologists from Kumasi were trained in histotechnology in Norway, they were returned to Kumasi, and they produced histologic slides that were temporarily sent to Norway for diagnosis. Two Ghanaian doctors received pathology training for 4 years in Norway. Mutual visits by pathologists and technologists from the 2 hospitals were arranged for the introduction of immunohistochemistry and cytology. Pathologists from Norway visited Kumasi for 1 month each year during 2007-2010. Microscopes and immunohistochemistry equipment were provided from Norway. Other laboratory equipment and a new building were provided by the Ghanaian hospital., Results: - The Ghanaian hospital had a surgical pathology service from the first project year. At 11 years after the start of the project, the services included autopsy, surgical pathology, cytopathology, frozen sections, and limited use of immunohistochemistry, and the department had 10 residents at different levels of training., Conclusions: - A Ghanaian pathology department that performed autopsies only was developed into a self-supported department with surgical pathology, cytology, immunohistochemistry, and frozen section service, with an active residency program and the capacity for further development that is independent from assistance abroad.

Abstract

Equol (a bacterial metabolite of the soy isoflavone daidzein) is produced by 30% to 50% of humans and may be associated with health outcomes. We hypothesized that plasma equol would be inversely associated with risks of fibrocystic breast conditions (FBC) and breast cancer (BC). Plasma from women in a breast self-examination trial in Shanghai with BC (n=269) or FBC (n=443), and age-matched controls (n=1027) was analyzed for isoflavones. Equol was grouped into categories (<20, 20-<45, and ≥45nmol/L) and, among women with daidzein ≥20nmol/L, the log10 equol:daidzein ratio was grouped into tertiles. Where available, non-cancerous tissue (NCT) adjacent to the carcinomas from women with BC were classified as non-proliferative or proliferative (n=130 and 172, respectively). The lesions from women with FBC were similarly classified (n=99 and 92, respectively). Odds ratios (OR) and 95% confidence intervals (CI) were calculated across equol categories and tertiles of log10 equol:daidzein ratio. Equol categories were not associated with FBC or BC (P>.05). For log10 equol:daidzein, compared to controls there were positive associations in the mid tertile for proliferative FBC (OR 2.06, 95% CI 1.08-3.93), BC with proliferative NCT (OR 2.95, 95% CI 1.37-6.35), and all BC regardless of histology (OR 2.37, 95% CI 1.43-3.95). However, trends in ORs with increasing plasma equol values or equol:daidzein ratios were not observed (P>.05). The results of this study do not provide evidence that equol plays a role in the etiology of these breast conditions. However, further work is needed to confirm or refute this conclusion., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Abstract

Breast carcinoma develops gradually through multiple steps, some of which are recognizable as benign or premalignant histological changes. The age-standardized breast-cancer incidence rate is three times higher in Norway than in Ghana. A similar difference in the prevalence of benign and premalignant breast changes in the general populations would be expected if the difference in incidence rates were mainly due to cancer initiation factors, but not if it were caused by later stage promotion and progression factors. Breast tissue was taken by a standardized protocol from the autopsies of 44 Ghanaian and 26 Norwegian women between 15 and 60 years of age. Blind-labelled hematoxylin and eosin stained sections were examined independently by each of the three authors and the occurrence of histological changes in each section was recorded. The study revealed no significant difference between Norwegian and Ghanaian women in the prevalence of either proliferative or non-proliferative breast changes. The recorded incidence of breast cancer in Ghana may be under-estimated because of lower access to health services, lower patient awareness, and absence of population screening for breast cancer. Otherwise, the results support the conclusion that the lower incidence of breast cancer in Ghana than in Norway is mainly due to late-stage promotion and progression rather than initiation factors.

Abstract

Hormonal treatment of breast cancer is effective only in patients whose tumors express estrogen and/or progesterone receptors (ER, PR). Receptor assessment is often not available in low-resource areas, and the choice may be to apply endocrine therapy to all or none of breast cancer patients, depending on the proportion of patients that can be expected to respond. Fifty-one invasive breast cancers from Ghana and 100 from Norway diagnosed in the same laboratory during the same time period were reexamined in a blinded slide review. Of Ghanaian tumors, 76% were ER+ (≥1% ER+ tumor cells). Of Norwegian tumors, 85% were ER+. Triple-negative tumors were seen in 22% of Ghanaian patients and in 7% of Norwegian patients. A review of previous similar studies in sub-Saharan patients shows very discrepant results. Standardization and quality control of receptor assessment and well-designed clinical trials in sub-Saharan African breast cancer patients are needed to give a sound basis for endocrine treatment in this area., (© 2014 Wiley Periodicals, Inc.)

Abstract

Background: Fever of unknown origin and high sedimentation rate are common clinical problems., Material and Methods: A middle-aged man with fever of unknown origin, night sweats and high sedimentation rate was referred to our hospital for investigation., Results and Interpretation: The patient was suspected to have mononucleosis or reactivation of infectious mononucleosis because of mild anaemia and thrombocytopenia, a weakly positive IgM antibody test for Epstein-Barr virus and monocytosis (in peripheral blood). Because monocytosis, elevated sedimentation rate and fever persisted, bone marrow smears were prepared and biopsies taken.The third biopsy showed that morphology was consistent with chronic myelomonocytic leukemia (CMML), which was confirmed by two later biopsies. However, a malignant cell population (consisting of blasts in peripheral blood) was only found in one of several flow cytometry assessments of peripheral blood and bone marrow aspirate and cytogenetic analyses of bone marrow cells were normal. The patient's clinical situation has been stable for some years and treatment has not been necessary.

Abstract

Background: Polymorphisms in sex hormone receptor-encoding genes may alter the activity of sex hormone receptors and thereby affect susceptibility to breast cancer and related outcomes., Methods: In a case-control study of women from Shanghai, China, we examined the risk of breast cancer and fibrocystic breast conditions associated with the ESR1 PvuII (rs2234693) and XbaI (rs9340799) and AR CAG repeat ((CAG)(n)) and GGC repeat ((GGC)(n)) polymorphisms among 614 women with breast cancer, 467 women with fibrocystic conditions, and 879 women without breast disease. We also evaluated whether risk differed by the presence/absence of proliferative changes (in the extratumoral epithelium or fibrocystic lesion), menopausal status, or body mass index (BMI). Age-adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) were calculated using logistic regression., Results: Only associations with AR (CAG)(n) and (GGC)(n) genotypes were detected. Allocating AR (CAG)(n) genotypes into six categories, with the (CAG)(22-24)/(CAG)(22-24) genotype category designated as the reference group, the (CAG)(>24)/(CAG)(>24) genotype category was associated with an increased risk of fibrocystic breast conditions (OR, 1.8; 95% CI, 1.1-3.0). Relative to the AR (GGC)(17)/(GGC)(17) genotype, the (GGC)(17)/(GGC)(14) genotype was associated with elevated risks of incident breast cancer (OR, 2.6; 95% CI, 1.3-5.4) and fibrocystic conditions (OR, 2.3; 95% CI, 1.1-4.5). Results did not differ according to proliferation status, menopausal status, or BMI., Conclusion: Although these data lend support for a link between AR variation and breast disease development, given the low frequency of the putative risk-conferring genotypes and other constraints, further confirmation of our results is needed., (Copyright © 2010 Elsevier Ltd.

Abstract

Fibroadenomas are common benign breast conditions among women and account for approximately 50% of breast biopsies performed. Dietary factors are known to influence benign breast conditions in the aggregate, but little is known of their association specifically with fibroadenoma. Our objective in this study was to evaluate the association between dietary and other factors and fibroadenoma risk. A case-control study, nested in a randomized trial of breast self-examination (BSE) in Chinese textile workers in Shanghai, China, was conducted between 1989 and 2000. The study sample included 327 affected women and 1070 controls. Women were administered a FFQ and a questionnaire that elicited reproductive and gynecological history and other information. Odds ratios, as estimates of relative risks, were calculated using multivariate conditional logistic regression. Significant decreasing trends in risk of fibroadenoma were observed with intake of fruits and vegetables and with number of live births, and a reduced risk was also associated with natural menopause, oral contraceptive use, and moderate exercise (walking and gardening). Increased risk of fibroadenoma was associated with heavy physical activity in one's 20s, breast cancer in a first-degree relative, and a history of prior benign breast lumps; and significant increasing trends in risk were observed with numbers of BSE per year and years of education. In conclusion, a diet rich in fruits and vegetables and the use of oral contraceptives may reduce risk of fibroadenoma.
