Tamoxifen and breast cancer risk in women harboring a BRCA1 germline mutation: computed efficacy, effectiveness and impact.

The management of breast cancer prone women remains a tough issue despite the release of institutional guidelines. Currently, only the anti-estrogen agent Tamoxifen and prophylactic surgery are claimed to decrease breast cancer incidence. However, efficacy of Tamoxifen, particularly in BRCA1 gene carriers, remains controversial and acceptability of prophylactic surgery is low. To evaluate the expected impact of Tamoxifen in preventing hereditary breast cancers, a modelling was made according to the efficacy of the treatment with respect to biological predictors of response: estrogen receptor (ER) and pS2 status of a series of 33 BRCA1-related breast cancers (BRCA1-BCs), and using data on BRCA1-BCs penetrance, as well as compliance and acceptability of the strategy. Although, 88% of BRCA1-BCs are ER negative in our series, 30% of cases are pS2 positive, implying a potential hormonal sensitivity of a proportion of these cancers. From our modelling, the expected impact of Tamoxifen in BRCA1 gene carriers is a reduction of breast cancer incidence of about 10% according to acceptability and compliance, close to that of 5% and of 13.5% for prophylactic mastectomy, according to acceptability rates from US and French surveys respectively. Since autonomy of choice is the root of western ethics, cancer prone women should be informed about the low but valuable expected reduction of incidence of breast cancer using Tamoxifen preventive therapy.

Disclosure to the family of breast/ovarian cancer genetic test results: patient's willingness and associated factors.

Informed probands are key actors for disclosing genetic information to their relatives when a mutation has been identified in the family. The objectives were to study women's attitudes towards the family disclosure of positive breast cancer genetic testing results and to determine the predictive factors of the diffusion patterns observed. A national multi-center cross-sectional survey was carried out at five French cancer genetic clinics during a 1-year period. Self-administered questionnaires were completed after the consultation by 84.5% (398/471) of women attending breast cancer genetic clinics for the first time. Among the 383 respondents who had at least one living first-degree relative to inform, 8.6% would inform none, 33.2% would inform at least one of them, and 58.2% would inform all of them. The sibship would be the most frequently informed blood relatives, sisters in 86.9% and brothers in 79% compared with mother in 71.4%, children in 70.4%, and father in 64.9%. Women of the family would be more frequently informed than men (P < 0.05). After multivariate adjustment, age, the fact to be affected by cancer, the number of daughters, and the emotional disturbance due to cancer in a close relationship were the main determinants (P < 0.05) of the diffusion patterns observed. The first step of the relatives' attendance to genetic counseling and the proband's willingness to disclose breast cancer genetic tests results was high in this study and was clearly dependent on the women's personal and emotional characteristics.

Physicians' attitudes towards mammography and prophylactic surgery for hereditary breast/ovarian cancer risk and subsequently published guidelines.

After a BRCA mutation has been identified in the context of hereditary breast/ovarian cancer (HBOC), mammographic screening and prophylactic surgery are two of the main options available to those responsible for the clinical management of healthy women. The aim of this study was to describe the attitudes of specialists towards the clinical management of women with an HBOC risk: this information was collected prior to the publication of the recent French guidelines. A random national sample of 1169 French surgeons, gynaecologists and obstetricians was surveyed using a mailed questionnaire, to which 700 of these physicians (60%) responded. When dealing with a BRCA mutated woman, 88.6% of the respondents said they would recommend mammographic screening, but only 27.1% would recommend that it should be carried out annually from the age of 30 years onwards, as recommended in the French guidelines; 10.9% would find it acceptable to propose prophylactic mastectomy from the age of 30 years, and 22.9% would find it acceptable to propose prophylactic oophorectomy from the age of 35 years. The specialists who agreed with recommending breast/ovarian cancer genetic testing also had more positive attitudes towards prophylactic mastectomy (adj OR = 3.4, 95% CI = 1.4-8.2), as did those who had previously recommended prophylactic mastectomy when gene testing was not yet available (adj OR = 2.06, 95% CI = 1.23-3.44). The respondents' attitudes towards prophylactic oophorectomy and mastectomy were significantly associated (adj OR = 3.9; 95% CI = 2.3-6.5). Previous recommendation of prophylactic mastectomy was associated (P < 0.01) with a higher level of knowledge of breast/ovarian cancer genetics and with medical practice in this field. French physicians' attitudes towards mammographic screening and prophylactic surgery were not in complete agreement with the subsequently published French guidelines, the impact of which has now to be considered. Constantly evolving knowledge about the efficacy of preventive intervention will give practitioners new elements to integrate into their counselling.

[Knowledge and management of psychological side effects of chemotherapies].

This review on psychological consequences of chemotherapies presents the research directions developed during the last two years: the first direction is a descriptive one and identifies the prevalence of psychological syndromes associated with these treatments. Besides psychological distress such as anxiety and depression, often underestimated in medical practice, some secondary cognitive deficiencies ought to be considered. It is also emphasized that the point of view of patients should be taken into account since their own assessment of the side effects is often discrepant with those of their medical providers. The second orientation developed here is the evaluation of actions aimed at controlling and alleviating the psychological consequences of these treatments by different protocols of information and psychotherapy. Good quality research is necessary in psycho-oncology in France and should be co-ordinated with clinical practice in psychology the offer of which is still too limited in our present health care system.

Cancer genetic clinics: why do women who already have cancer attend?

Cancer patients attend oncogenetic clinics so that the existence of a genetic risk can be checked and the relatives informed. The aim of this study was to describe the expectations of cancer patients about genetic counselling and their beliefs about the aetiology of their disease. A survey based on self-administered questionnaires before and after the consultation was carried out on 115 women with breast/ovarian cancer who attended one of the six French participating clinics. In 59 cases (51%), the consultees' expectations focused on the preventive options available and in 86 cases (75%) on their offspring; 87 (76%) found the consultation informative. On average, the women rated heredity and diet as lower risk factors (P < 0.05) after the consultation than before. Heredity, stress and the environment were thought to be more decisive than diet, smoking and alcohol. 34 patients who seemed unlikely to have a genetic risk in the consultant's opinion thought heredity to be less relevant (P < 0.05) after the consultation than before. At the time of the survey, cancer patients accounted for at least half of the consultees attending oncogenetic clinics in France. They need to have the clinical specificities of their disease and its medical management explained. They attend mainly for their offspring's sake, whereas healthy clients attend for their own sake.

Adoption and fostering of babies with Down syndrome: a cohort of 593 cases.

Recently, professionals in France have noticed an increase in newborns with Down syndrome (DS) being placed for adoption. The aim of this study was to investigate DS babies given up at birth for adoption and to consider the possible determinants of this in order to assess social acceptance of DS. A retrospective cohort of all living DS babies was collected from two birth-defect registries (Paris: 1981-1990; Marseilles area: 1984-1990). Follow-up data were collected: characteristics of the baby, biological parents and maternity units, age when given up for adoption, and type of foster care. The results showed that 19.4 per cent of infants with DS (115/593) were rejected by their parents. Multiple regression analysis indicated that foreign origin of the mother, area of residence, no associated major malformation, maternal age (15-24 years), and birth rank (> 2) variables were significantly associated with a lower placement rate. Among the 115 abandoned infants with DS, 88 came from unknown parentage (76.5 per cent). For half of them, adoptive placement (88/115) occurred before the age of 6 months. Socio-cultural attitudes play a great part in these family decisions. Equally important is the manner in which professionals propose adoption as an alternative to these parents of DS babies. They should be encouraged to consider all options before making a decision, so that the best solution can be found for the interest of all.

[Measurement of anxiety state in women: a short-form scale].

BACKGROUND: Clinical epidemiology and psychosocial studies often take into account the measurement of anxiety. Our objective was to develop and validate a short form scale of anxiety state from the Spielberger's State Trait Anxiety Inventory (STAI-Y), one of the most widely used scales. METHODS: This study was carried out on French samples of women with different levels of anxiety. The first step was to select from the original 20-items scale, the items susceptible to compose two short forms scales: an 8-items (18-STAI) and a 5-items (15-STAI) one. It was carried out on patients attending cancer genetic clinics (n1 = 160, n2 = 41). The second step was carried out on 3 other samples of women (n3 = 150, n4 = 167, n5 = 105) and measured the psychometric characteristics of the short-form scales obtained previously. RESULTS: The correlation coefficients between the short-forms and the complete 20-items form were very high (> 0.90) in particular for the 18-STAI (r > 0.95). Both short forms are sensitive to change. The internal consistency measured by Cronbach-alpha was comparable to the original scale. The results obtained with the 18 scale and another 10 items Spielberger's short-form scale are comparable and better than those with the 15 scale. CONCLUSION: The 18 French short-form scale, balanced with positive and negative items, can be recommended for the measurement of state anxiety when the complete form cannot be used.

Cancer genetics clinics: target population and consultees' expectations.

The aim of this study was to determine in healthy consultees attending cancer genetics clinics their risk status, their pathways leading to the clinics, their expectations and perception of cancer risk. In 1994, the consultees at six French centres completed a questionnaire before their first oncogenetic consultation. The oncogeneticists subsequently filled in a standardised form giving their risk assessment. Among the 206 healthy consultees, 91.3% were women, 92.2% had at least one cancer-affected first-degree relative and 73% had a "cancer family risk" as assessed by the oncogeneticist. Sixty-nine per cent of the consultees were referred to the clinics by a physician, 10.4% by their family and 18.8% on their own initiative: 83.5% of the sample perceived their family risk of cancer as being high and this belief was confirmed in 74.3% of the cases studied by the oncogeneticist. The families of self-referred consultees were less often at risk than those of consultees referred by a physician or by their family (P = 0.012). The majority (78%) expected to be informed about cancer prevention and screening, and this expectation depended on the consultee's level of education (P = 0.001). This study shows that medical pathways are more effective than the media as a means of reaching the members of the general population who are genuinely at risk, and shows that fuller information about prevention needs to be provided at cancer genetic consultations.

Attitudes towards cancer predictive testing and transmission of information to the family.

Before the organisation of breast cancer predictive testing in France, consultands' attitudes towards this kind of testing and towards passing on information about the family cancer risk to their relatives were investigated. This survey was carried out from January 1994 to January 1995 at six specialised cancer genetic clinics located in different parts of France Female consultands who were first degree relatives of cancer patients and who had at least one case of breast cancer in their family, affecting either themselves or a first degree relative or both, participated in this study. Among the 248 eligible consultands attending the clinics during the study period, 84.3% answered a post-consultation questionnaire. Among the 209 respondents, 40.7% (n = 85) were cancer patients and 59.3% (n = 124) were healthy consultands. A high consensus in favour of genetic testing was noted, since 87.7% of the sample stated that they would ask for breast cancer gene testing if this test became available. The underlying assumption of 96.6% of the women was that their health surveillance would be improved after a positive test. A high awareness of the anxiety that would be generated in a family after a positive result was observed and found to be associated (p < 0.05) with the anxiety and depressive profiles of the patients. Half of the healthy respondents said they would not change their attitude towards screening if the results of predictive testing turned out to be negative. Only 13.7% of the 161 patients who stated that the oncogeneticists asked them to contact their relatives firmly refused to do so, mainly because of difficult family relationships.

[Attitudes towards screening and prevention of breast and ovarian cancers with hereditary predisposition. Survey by female gynecologists in the north of France].

Search for mutations of BRCA1 in women at hereditary risk for cancer is now possible. We asked the female gynaecologists of our county (north of France) their opinion about the search of a mutation of BRCA1 if they had a familial risk of breast cancer. Our aim was to obtain the opinion of informed women about their willingness to do the test for themselves and about the consequences they should accept. One hundred and eighty-three women received a questionnaire by post. The response rate was 56.3%. Twenty-four percent of the responders had a first degree relative with breast cancer. Most of the responders (87.4%; IC 95%: 81-93.8) would ask for the search of a mutation of BRCA1. The percentage of women who would accept the test is smaller for the women who have a first degree relative with breast cancer (72.0% vs 92.3%; P = 0.02). The reasons given to do the test were a better screening or prevention (69.7%) and the knowledge of a personal risk (49.4%). For breast cancer, 93.2% (95% CI: 88.4-98) would accept a screening protocol, 30.1% (CI: 21.3-38.9) would accept a prophylactic bilateral mastectomy. For ovarian cancer, 93.2% (CI: 88.4-98) would accept the screening, 52.4% (CI: 42.8-62) would accept a prophylactic ovariectomy. In conclusion, most of the informed women would ask for the test and the surgical options for reducing the risk of cancer are not absolutely rejected. Of course, only future studies will state precisely the choice of truly implicated women.

[Screening practices and familial antecedents of colorectal cancer. Survey with a voluntary population].

OBJECTIVES: To analyze the association between colorectal cancer positive family history and screening practices. METHODS: The study concerned 6733 individuals attending a center for periodic health examination. RESULTS: Five hundred fifty four patients (8.2%) declared a positive family history of colorectal cancer; 269 (4%) were first degree relatives of the affected member and among them, 73 (1.1%) have pointed out the occurrence of at least one cancer case below age 50. Out of 554 subjects with a family history (regardless the degree of kinship), 132 (23.8%) have had an endoscopic examination versus 8.9% of subjects without positive family history. The rate of endoscopy increased with the number of cases in a family (P < 0.0001). CONCLUSION: Family members undertake more endoscopic examinations when a family history of colorectal is reported. A correlation with the number of affected relatives has been found.

Attitudes towards Down's syndrome: follow up of a cohort of 280 cases.

A follow up study of a cohort of 280 Down's syndrome (DS) fetuses was initiated in order to estimate the percentage of terminations of pregnancy, the prevalence at birth, the survival of DS children, the attitude of the parents at birth, and the medical and surgical care provided. The present study is a preliminary analysis of the data collected up to the age of 1 year. It shows that 43% of the 280 DS fetuses had died by the end of the first year of life, owing to termination of pregnancy (27%), late spontaneous abortion or stillbirth (4%), or death during the first year of life (12%). Among the 33 children who died, 12 had a common atrioventricular canal, six had another major malformation, three died from infection, one from respiratory distress, two were cot deaths, and one was an infanticide, but eight deaths were unexplained, occurring in children with no known malformation or disease. Among the 185 children still alive after 2 days, 23 (12%) were available for adoption, their mothers having elected to remain anonymous. These results show that in some instances parents or professionals feel justified on one hand in not providing DS children with the necessary care and on the other hand to transfer their responsibilities to the public health system. The influence of prenatal diagnosis of chromosome disorders as a determining factor of the social acceptance of DS is still questionable.

Reasons for women's non-uptake of amniocentesis.

More than 10 years after a chromosomal anomaly screening programme was set up in France for pregnant women of advanced age, amniocentesis is still a controversial issue. The reasons why eligible women did not utilize the test and whether or not the existence of social welfare coverage determined women's access to prenatal diagnosis were studied. A group of 291 women aged > or = 35 years who recently gave birth to normal liveborns was interviewed by telephone. Among those aged 38 years and over, who automatically qualified for social security coverage, 75 per cent had undergone amniocentesis as opposed to 23 per cent in the 35 to 37-year-old non-covered age group who did not qualify for social security coverage. In both groups, access to amniocentesis was found to depend on the physicians', women's and male partners' attitudes towards prenatal diagnosis and abortion. Among the younger group, the uptake depended mainly on socio-economic factors. Institutional policies should ensure greater equality of access while allowing for individual preferences.
