Abstract Aim: To examine the use of complementary and alternative medicine (CAM) by women with varying levels of familial and perceived risk of breast cancer with the goal of preventing breast cancer. Methods: Cross-sectional data on CAM use were collected on 2,198 women (mean age, 63 years) personally unaffected by breast cancer in the Minnesota Breast Cancer Family Study. CAM use was compared across women at high, moderate, or average risk based on family history, as well as across categories of perceived risk of breast cancer. CAM use was also examined in relation to screening and general health behaviors, worry about breast cancer, and optimism. Results: Half (49.5%) of the women reported using at least one CAM modality with the intent of preventing breast cancer. Univariate analyses indicated that greater overall CAM use was related to greater perceived risk (P = 0.018), more general health behaviors (P < 0.0001), more breast cancer screening behaviors (P = 0.0002), greater optimism (P = 0.0002), and higher educational attainment (P < 0.0001). Multivariate analysis revealed that general health behaviors (P < 0.0001), education (P = 0.0027), and optimism (P = 0.037) were significant predictors of CAM use when in the same model with perceived risk and breast cancer screening behaviors. Conclusions: Many women use CAM with the goal of preventing breast cancer. General health-promoting behaviors, education, and optimism predict CAM use. Evidence-based guidance is needed for the public and health care providers on the potential and limitations of specific CAM approaches to affect cancer risk.

Objective: Mother-daughter communication may be a potential pathway between family history and cancer prevention behavior. We examined the degree to which mothers reported providing advice on breast cancer prevention to their daughters, the content of such advice, and correlates of providing such advice. Methods: Data were collected via a mailed questionnaire to 1773 women from 355 families in the Minnesota Breast Cancer Family Study. Women were asked whether or not they had provided advice to their daughters on what they should do to prevent breast cancer. An additional open-ended question asked them to describe the types of advice they had provided. Results: Nine hundred seventy-six (55%) of the women reported providing breast cancer prevention advice to their daughters. The most frequent types of advice were to have a mammogram (51%), perform breast self-examination (BSE) (39%), have a clinical breast examination (CBE) (30%), and maintain a healthy lifestyle (21%). From multivariate logistic regression, older age ( p < 0.001), having a personal history of breast cancer ( p < 0.001), higher degree of breast cancer worry/concern ( p < 0.001), engaging in a higher number of health-promoting behaviors ( p < 0.001), and ever performing a BSE ( p = 0.04) were factors independently associated with the provision of advice. Analyses accounting for sample nonindependence did not change our results. Conclusions: Breast cancer prevention behaviors were associated with providing advice. By better understanding the pathways through which breast cancer family history is associated with screening mammography and other prevention behaviors, researchers can develop more effective, tailored prevention interventions at the family level.

Purpose Atypical hyperplasia is a well-recognized risk factor for breast cancer, conveying an approximately four-fold increased risk. Data regarding long-term absolute risk and factors for risk stratification are needed. Patients and Methods Women with atypical hyperplasia in the Mayo Benign Breast Disease Cohort were identified through pathology review. Subsequent breast cancers were identified via medical records and a questionnaire. Relative risks (RRs) were estimated using standardized incidence ratios, comparing the observed number of breast cancers with those expected based on Iowa Surveillance, Epidemiology, and End Results (SEER) data. Age, histologic factors, and family history were evaluated as risk modifiers. Plots of cumulative breast cancer incidence provided estimates of risk over time. Results With mean follow-up of 13.7 years, 66 breast cancers (19.9%) occurred among 331 women with atypia. RR of breast cancer with atypia was 3.88 (95% CI, 3.00 to 4.94). Marked elevations in risk were seen with multifocal atypia (eg, three or more foci with calcifications [RR, 10.35; 95% CI, 6.13 to 16.4]). RR was higher for younger women (< 45; RR, 6.76; 95% CI, 3.24 to 12.4). Risk was similar for atypical ductal and atypical lobular hyperplasia, and family history added no significant risk. Breast cancer risk remained elevated over 20 years, and the cumulative incidence approached 35% at 30 years. Conclusion Among women with atypical hyperplasia, multiple foci of atypia and the presence of histologic calcifications may indicate “very high risk” status (> 50% risk at 20 years). A positive family history does not further increase risk in women with atypia.

There has been much research documenting the impact of having a loved one diagnosed with advanced cancer, but little is known about how to reduce care-giver burden. In this randomized controlled trial, the authors examined the potential relationship of an advanced cancer patient’s participation in an 8-session, structured, multidisciplinary intervention on the care-giver’s burden and quality of life (QOL). Although the patients randomly assigned to the intervention (n = 54) demonstrated improved QOL compared to the control condition (n = 49) participants ( P < .05), there was no evidence that improving the patient’s QOL made an impact on the caregiver’s level of burden or the care-giver’s QOL. Further investigation is warranted in this area, including interventions specifically designed and targeted to both reduce caregiver burden and to improve caregiver QOL.

Purpose The primary goal of this study was to evaluate the feasibility and effectiveness of a structured, multidisciplinary intervention targeted to maintain the overall quality of life (QOL), which is more comprehensive than psychosocial distress, of patients undergoing radiation therapy for advanced-stage cancer. Patients and Methods Radiation therapy patients with advanced cancer and an estimated 5-year survival rate of 0% to 50% were randomly assigned to either an eight-session structured multidisciplinary intervention arm or a standard care arm. The eight 90-minute sessions addressed the five domains of QOL including cognitive, physical, emotional, spiritual, and social functioning. The primary end point of maintaining overall QOL was assessed by a single-item linear analog scale (Linear Analog Scale of Assessment or modified Spitzer Uniscale). QOL was assessed at baseline, week 4 (end of multidisciplinary intervention), week 8, and week 27. Results Of the 103 participants, overall QOL at week 4 was maintained by the patients in the intervention (n = 49), whereas QOL at week 4 significantly decreased for patients in the control group (n = 54). This change reflected a 3-point increase from baseline in the intervention group and a 9-point decrease from baseline in the control group (P = .009). Intervention participants maintained their QOL, and controls gradually returned to baseline by the end of the 6-month follow-up period. Conclusion Although intervention participants maintained and actually improved their QOL during radiation therapy, control participants experienced a significant decrease in their QOL. Thus, a structured multidisciplinary intervention can help maintain or even improve QOL in patients with advanced cancer who are undergoing cancer treatment.

Purpose Contralateral prophylactic mastectomy (CPM) is one option for reducing the risk of a second breast cancer in women with a personal and family history of breast cancer. Few data are available regarding satisfaction, psychological, and social function after CPM. The purpose of this research is to evaluate women’s long-term satisfaction with CPM, factors influencing satisfaction, and psychological and social function after CPM. Patients and Methods This was a descriptive study of all women with a family history of breast cancer, known to be alive, who elected CPM at Mayo Clinic (Rochester, MN) between 1960 and 1993 (n = 621). Ninety-four percent of the women (n = 583) completed a study-specific questionnaire. Results A mean of 10.3 years after the procedure, the majority of women (83%) were satisfied with their CPM. A smaller number were neutral (8%) or dissatisfied (9%). Women who had a subcutaneous mastectomy had more problems with reconstruction, and fewer of these women were satisfied than women with simple mastectomy. Decreased satisfaction with CPM was associated with decreased satisfaction with appearance, complications with reconstruction, reconstruction after CPM, and increased level of stress in life. The majority of women experienced no change or favorable effects in self-esteem (83%), level of stress in life (83%), and emotional stability (88%). Satisfaction with body appearance, feelings of femininity, and sexual relationships were the most adversely affected with 33%, 26%, and 23% of the women responding negatively. Conclusion Although most women are satisfied with CPM, each woman should weigh the benefits alongside the potential adverse effects.
