Early cancer detection programmes for women at high risk for breast and ovarian cancer: a proposal of practical guidelines

Women from families with multiple breast and/or ovarian cancers may be at increased risk to develop breast/ovarian cancer themselves. Due to personal experience with family members having these diseases they are anxious and ask for specific prophylactic measurements or treatment. The detection of two susceptibility genes, BRCA1 and BRCA2, has given insight into the genetic background of part of the familial breast/ovarian cancer syndromes. This has led to an increased demand in genetic counselling, testing, and early cancer detection programmes. Prospective data from early cancer detection programmes in this high risk population are yet not available. Based on data from epidemiological risk studies, breast and ovarian screening programmes and follow up data from breast cancer trials recommendations for an early cancer detection programme have been summarized. At the present these recommendations are tested in a prospective trial.     

Psychological support needs for women at high genetic risk of breast cancer: some preliminary indicators

OBJECTIVE: To determine the relationship between impairments, disability and handicap in reflex sympathetic dystrophy (RSD) patients. DESIGN: A long-term follow-up study of upper extremity RSD patients. SETTING: A university hospital. SUBJECTS: Sixty-five patients, 3-9 years (mean interval 5.5 years) after RSD of the upper extremity (mean age 50.2 years). MAIN OUTCOME MEASURES: Impairments: range of motion, moving two point discrimination, muscle strength of the hand and pain were measured. Disability was assessed with the Groningen Activity Restriction Scale (GARS) and handicap was assessed with three subscales (social functioning, role limitations due to physical problems and role limitations due to emotional problems) of the RAND-36. RESULTS: After RSD of the upper extremity, 62% of the patients are limited in activities of daily living (ADL) and/or instrumental ADL (IADL). Pain and restrictions in forward flexion of the shoulder, thumb opposition and grip strength are the most important impairments limiting ADL and IADL. Patients with limitations in ADL and IADL are significantly more handicapped than patients without limitations. Pain is the most important factor contributing to handicap. CONCLUSION: The relationship between impairments and disability and between disability and handicap in RSD patients is weak to moderate. Pain is the most important factor leading to disability and handicap.     

Breast cancer risk among women using silicone gel breast implants

Since their introduction in 1962, silicone gel-filled breast implants have been used by an estimated one to two million women. Questions concerning an increased cancer risk to these women have been raised. A review of the medical literature, including case reports, case series, physician surveys, case-control studies, and cohort studies, failed to turn up any evidence which associated the use of silicone breast implants with either an increased risk of breast cancer or an increased risk of a more advanced stage of cancer at the time of cancer diagnosis. The available data do not indicate any significant difference between the characteristics of the breast cancers of women with breast implants and those of women in control populations.     

Decision-making about genetic testing among women at familial risk for breast cancer

PURPOSE: To explore the effects on the lacrimal gland of adenovirus infection of the cornea. METHODS: Rabbit corneas were inoculated with human adenoviruses Ad5, Ad14, or a rabbit adapted form of Ad 5, and in some instances booster inoculations were given. Sections of lacrimal glands removed 21-59 days post-inoculation were immunostained using antibodies against rabbit Class I and Class II MHC molecules, CD4, CD8, CD18, and rabbit thymic lymphocyte antigen (RTLA). Relative numbers of positively stained cells were quantified with a Metamorph image analysis system. RESULTS: RTLA and CD18 antigens were expressed on many interstitial cells in the normal lacrimal gland, but few expressed CD4 or CD8. The number of RTLA+ cells increased by 60-100% after inoculation of Ad5 and after boosting, and CD18+ cells increased from 33-100% after inoculation of Ad5 and after boosting. Booster inoculations also caused focal lymphocytic infiltration. MHC Class I was expressed on interstitial cells and duct epithelium, but not acinar cells, and there was no detectable difference after viral infection. In controls, MHC Class II was localized to a population of interstitial cells and a few acinar cells. A single inoculation of the Ad5 virus did not result in an increase in the total number of MHC Class II-positive cells at 21 days, but inoculation with the rabbit-adapted Ad 5 and booster inoculations caused a 30% increase. CONCLUSIONS: Ad5 and rabbit-adapted Ad5 infection of the cornea induce lymphocytic infiltration in the lacrimal gland, and the effect is enhanced by boosting. There is also an increase in expression of MHC Class II after inoculation with rabbit-adapted Ad5 and with booster inoculations.     

Marital status, marital satisfaction, and support processes among women at high risk for breast cancer.

This study explored marital status, social support processes, and psychological distress among women at high risk for breast and ovarian cancer who were anticipating genetic testing. In addition to substantive findings, it presents a means of using nonsense coding (J. Cohen & P. Cohen, 1983) to include unmarried persons in regression analyses examining the importance of marital support. These women had mobilized high levels of social support. Married and unmarried women did not differ in distress, but women had to have more satisfying marriages than average to be equivalent to unmarried women. For the married women, husbands were more involved and more influential in decision making than female relatives, even in distressed marriages. Negativity from close relationships, particularly the spouse, had more influence on these women's well-being than did positive involvement. The authors' findings suggest that counseling and education programs need to accommodate the key role that husbands have in decision making concerning genetic testing for risk of breast cancer.

Osteoporosis: primary prevention and intervention strategies for women at risk

The growth and development of the skeleton begins in early fetal life and continues for nearly two decades in a series of well-defined events. Minerals--particularly calcium but also carbonate, magnesium, sodium, and fluoride--play vital structural and metabolic roles in bone growth and development. However, bone formation also is encouraged by hormones, such as estrogen, and by weight-bearing activity. Living bone is never metabolically at rest; its matrix and mineral stores are being remodeled constantly along the lines of mechanical stress.     

Specific worry about breast cancer predicts mammography use in women at risk for breast and ovarian cancer.

This longitudinal study examined predictors of mammography use among women with a family history of breast cancer participating in a risk assessment and surveillance program (N?=?213). Assessed were background variables (age, prior mammography utilization), cognitive variables (perceived vulnerability), and affective variables (cancer worry and general distress). Results of logistic regression analyses predicting adherence 1 year after baseline contact, in which variables of prior utilization, feelings of vulnerability, and general distress were controlled for, indicated that and age were significant predictors of mammography adherence. Results suggest that moderate levels of cancer worry facilitate, rather than undermine, adherence. The results have implications for the construction of educational messages that should be designed to acknowledge feelings of cancer-specific worry and to provide guidance in health protective behaviors.

Breast conservation surgery for breast cancer at a regional medical center

Physical exercise is recommended for the prevention and treatment of osteoporosis. However, its exact role and effectiveness in adulthood is unclear. While vigorous exercise of long duration enhances bone density, few adult individuals comply with such training programs. The present study evaluates the influence of nonphysiological mechanical stimulation, in the form of low intensity vibration (frequency: 50 Hz, acceleration: 2 g, 30 min/day for 5 days/week), on the prevention of bone loss in an animal model of postmenopausal osteoporosis. In the ovariectomised groups of rats a statistically significant (p < 0.05) decrease of bone density (femur and tibia) was recorded at 5 weeks postovariectomy. This effect was maintained for the 12 week duration of the study. Vibration prevented early bone loss after ovariectomy. Vibrated ovariectomised rats showed statistically significantly higher (p < 0.05) BMD values compared to those of their ovariectomised controls at 5 weeks. Vibration did not influence the bone density of the SHAM-operated rats. Although vibration increased ultimate strength (fracture load of the rat femur) in the ovariectomised rats, this finding was not statistically significant. Our data indicate that this method of safe and easily applicable vibration, in the form of a vibrating platform, is effective in preventing early postovariectomy bone loss in an animal model.     

Breast cancer detection by daughters of women with breast cancer

The preferred therapy for genuine stress incontinence is surgery. The Burch procedure is considered by many to be the gold standard for surgical treatment of genuine stress incontinence. The Burch procedure requires the elevation of the anterior wall of the vagina to the level of the origin of the paravaginal fascia by suspension from Cooper's ligaments. The laparoscopic performance of the Burch procedure by suturing or by endoscopic stapler mesh technique results in a decrease in the length of hospital stay, faster recovery, much shorter catheterization and less scarring due to the smaller incisions. The laparoscopic procedure provides results similar to the open operation if a meticulous technique is used. Long-term follow-up will be necessary before these procedures can be generally offered as a therapeutic alternative.     

Tumor risk consultation for predisposed women from high risk cancer families

Germline mutations of the cancer susceptibility genes BRCA1 and BRCA2 seem to lead to a very high risk for breast and/or ovarian cancer. Therefore, genetic counselling and identification of high-risk families may be essential to offer the opportunity to participate in a specific early cancer detection program and to provide individualized psychological support. In a two year period (August 1994-August 1997) 304 consultees present for genetic counselling at the interdisciplinary cancer genetic clinic (Department of Obstetrics & Gynecology and Human Genetics, Heinrich-Heine-Universit?t, Düsseldorf). For genetic testing a BRCA1/2 mutation detection strategy including protein truncation test (PTT), single strand conformation polymorphism (SSCP), and direct DNA sequencing is used. 161 families fulfilled the inclusion criteria; at present, 72 families for whom complete analytical material is available are analyzed. Although genetic testing for BRCA1 and BRCA2 is technically challenging, women with a family history of multiple sporadic breast/ovarian cancers and those with a hereditary BRCA1 and BRCA2 gene defect may be distinguished. For the first group of consultees this may ease their concern, for the second group preventive measures including an early cancer detection or prevention program, psychological support or prophylactic surgery may be discussed.     

The North Carolina Breast Cancer Screening Program: foundations and design of a model for reaching older, minority, rural women

Breast cancer screening programs do not reach all women at the same rate. Screening mammography use varies according to sociodemographic characteristics; mammography utilization is highest among women in their fifties but then decreases with age. In North Carolina, breast cancer is a particular burden for Black and lower-income women. Black women are more likely to be diagnosed with late stage disease, and their rate of breast cancer mortality is higher than it is for White women even though the incidence in White women is greater. Older, Black, and low-income women are less likely to obtain screening by mammography and clinical breast examination. The Black-White gap is even more pronounced among rural women, in part because they are more likely to be poor. The North Carolina Breast Cancer Screening Program (NC-BCSP) was established to increase the rate of regular mammography screening by an absolute 20% in 3 years among older Black women ages 50 and older in five rural counties in the eastern part of the state. In this paper, we describe the genesis of this comprehensive community intervention model, highlighting the behavioral science constructs, health education principles, and theories of behavioral and organizational change that form its conceptual foundation. NC-BCSP's theoretical foundations include the social ecological perspective, the PRECEDE model of health promotion, the Health Belief Model of individual change, and the "stages of change" transtheoretical model. We also review the experiences and lessons learned from two previous outreach initiatives in North Carolina that provided valuable "lessons" in the development of the NC-BCSP intervention model. In the second half of the paper, we describe the actual NC-BCSP interventions, activities, and evaluation tools, citing specific examples of how the underlying theories are implemented. NC-BCSP's goal goes beyond individual behavior change to raise low mammography screening rates among Black women in rural North Carolina. Its ultimate objective is to create linkages across agencies, and between agencies and communities, that will endure after the research project ends.     

Diet and breast cancer risk in a cohort of Finnish women

The associations between dietary antioxidant vitamins, dietary fiber, and selected foods and risk of breast cancer were studied in 4697 initially cancer-free women, aged 15 years or older. At baseline (1967-1972) the women were interviewed for total habitual diet over the preceding year. During a 25-year follow-up period 88 breast cancer cases were diagnosed. There was a significant inverse gradient between milk consumption and occurrence of breast cancer, whereas higher consumption of fried meat was associated with increased risk of breast cancer. No significant relationships were found between the intakes of vitamin E, vitamin C, beta-carotene, lycopene, lutein or dietary fiber and the occurrence of breast cancer.     

Genetic counseling for families at high cancer risk

About 5-10% of the most common cancers, such as breast, colon and melanoma, result from mutations in inherited predisposition genes. Recently some of these genes have been mapped or even cloned. These advances in cancer genetics have made more precise genetic counseling possible for cancer patients and their families. In our clinic for specific genetic counseling 180 families with a history of cancer were seen during a 10-month period. In counseling sessions, the family history was confirmed and interpreted, personal risk was estimated and the availability of molecular genetic testing was presented. Blood samples for DNA testing were drawn from those with certain criteria who wished to be tested. Instructions for early detection were also given, depending on the personal risk of cancer as compared to that of the general population.     

The role of hormone replacement therapy in the risk for breast cancer and total mortality in women with a family history of breast cancer

BACKGROUND: The risks and benefits of hormone replacement therapy (HRT) are of considerable interest and importance, especially in terms of whether they differ among subsets of women. OBJECTIVE: To determine whether HRT is associated with increased risks for breast cancer and total mortality in women with a family history of breast cancer. DESIGN: Prospective cohort study. SETTING: Population-based sample of midwestern post-menopausal women enrolled in an observational study of risk factors for cancer. PARTICIPANTS: Random sample of 41,837 female Iowa residents 55 to 69 years of age. MEASUREMENTS: Incidence rates of and relative risks for breast cancer (n = 1085) and total mortality (n = 2035) through 8 years of follow-up were calculated by using data from the State Health Registry of Iowa and the National Death Index. RESULTS: A family history of breast cancer was reported by 12.2% of the cohort at risk. Among women with a family history of breast cancer, those who currently used HRT and had done so for at least 5 years developed breast cancer at an age-adjusted annual rate of 61 cases per 10,000 person-years (95% CI, 28 to 94 cases); this rate was not statistically significantly higher than the rate in women who had never used HRT (46 cases per 10,000 person-years [CI, 36 to 55 cases]). Among women with a family history, those who used HRT had a significantly lower risk for total mortality than did women who had never used HRT (relative risk, 0.67 [CI, 0.51 to 0.89]), including total cancer-related mortality (relative risk, 0.75 [CI, 0.50 to 1.12]). The age-adjusted annual mortality rate for women using HRT for at least 5 years was 46 deaths per 10,000 person-years (CI, 19 to 74 deaths); this is roughly half the rate seen in women who had never used HRT (80 deaths per 10,000 person-years [CI, 69 to 92 deaths]). CONCLUSIONS: These data suggest that HRT use in women with a family history of breast cancer is not associated with a significantly increased incidence of breast cancer but is associated with a significantly reduced total mortality rate.     

The Gothenburg Breast Cancer Screening Trial: preliminary results on breast cancer mortality for women aged 39-49

We carried out a randomized trial of invitation to screening mammography in the city of Gothenburg, Sweden, to estimate the effect of screening on breast cancer mortality in women under age 50 years. A total of 11,724 women aged 39-49 were randomized to the study group, which was invited to mammographic screening every 18 months; 14,217 women in the same age range were randomized to a control group, which was not invited to screening until the fifth screen of the study group. Breast cancers diagnosed in both groups between randomization and immediately after the first screen of the control group were followed up for death from breast cancer to the end of December 1994. There was a significant 44% reduction in mortality from breast cancer in the study group compared to the control group (relative risk [RR] = 0.56, P = 0.042, 95% confidence interval [CI]: 0.32-0.98). A conservative estimate based on removal of the cancers detected at the first screen of the control group gave an RR = 0.59 (P = 0.069, 95% CI: 0.33-1.05). The true answer is likely to lie between the two estimates. These data suggest that mammographic screening can reduce breast cancer mortality in women under age 50, particularly if high-quality mammography is used and a short interscreening interval is adhered to.     

Lymphoedema: a study of Otago women treated for breast cancer

Lymphoedema, the swollen arm that can follow treatment for breast cancer, is the build up of lymph fluid which is unable to flow normally due to the surgical removal of axillary lymph nodes or the scarring of these nodes from radiotherapy. Previous studies indicate a lack of recognition of preventative measures and treatment of lymphoedema amongst health professionals and women treated for breast cancer. There also appears to be a lack of acknowledgement of the effects that lymphoedema can have on those who develop it. Of 181 women surveyed 68 (38%) reported having developed arm swelling at some stage since their treatment, 56 (31%) of whom met the study criteria for lymphoedema. Of those with lymphoedema 21 (37%) women had not consulted anyone regarding their swollen arm; a further 10 (18%) sought advice, but were offered no treatment. Therefore, in total, 31 (55%) of the women with lymphoedema received no treatment. The remaining 25 (45%) were offered a variety of treatments. In the group of women with lymphoedema, most arm swelling occurred within the first year. For a smaller number, swelling occurred up to 25 years later. Twenty-one percent of those affected, recalled advice about its prevention, compared with 36% in the group who had not experienced lymphoedema. Lifestyles were affected in many ways, with 21 (37.5%) of the women reporting pain of varying intensity and frequency. Other effects were on dress/choice of clothing, household duties, sleep, employment and sports.     

C-erbB-2 overexpression in primary breast cancer: independent prognostic factor in patients at high risk

The prognostic value of c-erbB-2 protein overexpression has been evaluated in 463 patients with operable breast cancer after a median follow-up of 66 months. Overexpression was observed in 99/463 (21%) of the breast tumors. It showed significant positive correlation to histological grade (p < 0.0001) and tumor size (p < 0.02). A relationship of borderline significance was observed between c-erbB-2 protein overexpression and negative or low estrogen receptor (ER) content. No significant correlation was found to lymph node involvement or proliferating tumor cell fraction as determined by the proliferating cell nuclear antigen (PCNA). After a median follow-up of 66 months (range 6 to 109 months), the overall survival of all patients amounted to 63%. Multivariate analysis revealed lymph node involvement, tumor size, histological grade, histological type, c-erbB-2 protein overexpression, progesterone receptor (PR) content, and oral contraceptive use as independent prognostic factors. In an univariate analysis, the overall survival amounted to 72% and 38% of tumor patients with negative and positive c-erbB-2 protein overexpression, respectively. The most significant finding is that c-erbB-2 overexpression has been recognized as an independent predictive factor in subsets of tumor patients who would be expected to have a generally poor prognosis, such as those indicating axillary lymph node involvement, large tumor size (> 2 cm), and PR negativity.
