To examine psychological distress in women at risk of familial breast-ovarian cancer (FBOC) or hereditary non-polyposis colorectal cancer (HNPCC) with absence of demonstrated mutations in the family ...(unknown mutation).
Two-hundred and fifty three consecutive women at risk of FBOC and 77 at risk of HNPCC and with no present or past history of cancer. They were aware of their risk and had received genetic counseling. Comparisons were made between these two groups, normal controls, and women who were identified to be BRCA1 mutation carriers. The questionnaires Beck Hopelessness Scale (BHS), General Health Questionnaire (GHQ-28), Hospital Anxiety and Depression Scale (HADS) and Impact of Event Scale (IES) were employed to assess psychological distress.
No significant differences concerning psychological distress were observed between women with FBOC and women with HNPCC. Compared to mutation carriers for BRCA1, the level of anxiety and depression was significantly higher in the FBOC group with absence of demonstrated mutation. Compared to normal controls, the level of anxiety was higher, while the level of depression was lower in the groups with unknown mutation.
Women in the absence of demonstrated mutations have higher anxiety and depression levels than women with known mutation-carrier status. Access to genetic testing may be of psychologically benefit to women at risk for FBOC or HNPCC.
Several studies of survival in women with BRCA1 mutations have shown either reduced survival or no difference compared to controls. Programmes for early detection and treatment of inherited breast ...cancer, have failed to demonstrate a significant improvement in survival in BRCA1 mutation carriers.One hundred and sixty-seven women with disease-associated germline BRCA1 mutations and breast cancer from 1980 to 2001 were identified. Tumour characteristics, treatment given and survival were recorded. A control group comprising three hundred and four women matched for age, time of diagnosis and stage were used to compare survival.BRCA1 mutation carriers were found to have a poorer prognosis, which could be explained by neither the mode of surgical treatment nor the use of adjuvant chemotherapy. BRCA1 mutation carriers with node negative breast cancer had worse overall survival than controls.Our findings confirm the serious prognosis of BRCA1-associated breast cancer even when diagnosed at an early stage, and that type of treatment does not influence prognosis.
Penetrances of BRCA1 and BRCA2 mutations have been derived from retrospective studies, implying the possibility of ascertainment biases to influence the results.We have followed women at risk for ...breast and/or ovarian cancer for two decades, and report the prospectively observed age-related annual incidence rates to contract breast or ovarian cancer for women with deleterious BRCA1 or BRCA2 mutations based on 4830 observation years. Patients were grouped according to mutation, age and having/not having had previous cancer.In women not having had previous cancer and aged 40-59 years, the annual incidence rate to contract breast or ovarian cancer in those having the most frequent BRCA1 founder mutations was 4.0%, for women in this age group and with less frequent BRCA1 mutations annual incidence rate was 5.9%, and for women with BRCA2 mutations 3.5%.The observed figures may be used for genetic counseling of healthy mutation carriers in the respective age groups. The results may indicate that less frequent BRCA1 mutations have higher penetrances than BRCA1 founder mutations.
Background: Although quality of life (QoL) and mental distress in women belonging to familial cancer families have been studied, little is known on these matters in women with absence of demonstrated ...mutations. The aim of this study was to examine QoL and concer-related distress in such women. Methods: About 330 women at risk for familial cancers in the absence of demonstrated mutations were invited to the study. About 239 women (72%) (risk group) completed the Short Form 12 (SF-12) and the Impact of Event Scale (IES). The SF-12-findings were compared to the age-adjusted findings from the general female population (controls). Results: The risk group had significantly better physical QoL than controls, while no significant difference was found for mental QoL. Within the risk group the type of familial cancer did not make a significant difference in QoL, but to have a father with cancer or a deceased parent, was associated with increased risk of being a case with low QoL. Mental QoL showed moderate correlation with cancerrelated distress. Conclusions: Women belonging to familial cancer families in the absence of demonstrated mutations had at least as good QoL as controls in spite of living with a permanent cancer-related threat.
