RESUMO
BACKGROUND: Despite the questionable effectiveness of oral complementary and alternative medicine (OCAM) in relieving cancer-related symptoms, including fatigue (CRF), many patients use it aiming to improve their quality of life. We assessed factors associated with OCAM use, focusing on CRF. METHODS: Women with stage I-III breast cancer (BC) were included from CANTO (NCT01993498). OCAM use was defined as taking homeopathy, vitamins/minerals, or herbal/dietary supplements. Multivariable multinomial logistic regressions evaluated associations of CRF (EORTC QLQ-C30), patient, and treatment characteristics with OCAM use. RESULTS: Among 5237 women, 23.0% reported OCAM use overall (49.3% at diagnosis, 50.7% starting post-diagnosis), mostly homeopathy (65.4%). Mean (SD) CRF score was 27.6 (24.0) at diagnosis and 35.1 (25.3) at post-diagnosis. More intense CRF was consistently associated with OCAM use at diagnosis and post-diagnosis [adjusted odds ratio (aOR) for 10-point increase 1.05 (95% Confidence interval 1.01-1.09) and 1.04 (1.01-1.09) vs. never use, respectively]. Odds of using OCAM at diagnosis were higher among older [for 5-year increase, 1.09 (1.04-1.14)] and more educated patients [college vs. primary 1.80 (1.27-2.55)]. Women with income > 3000 [vs. < 1500 euros/month, 1.44 (1.02-2.03)], anxiety [vs. not, 1.25 (1.01-1.54)], and those receiving chemotherapy [vs. not, 1.32 (1.04-1.68)] had higher odds of using OCAM post-diagnosis. CONCLUSION: One-in-four patients reported use of OCAM. More severe CRF was consistently associated with its use. Moreover, older, better educated, wealthier, more anxious women, and those receiving chemotherapy seemed more prone to use OCAM. Characterizing profiles of BC patients more frequently resorting to OCAM may help deliver targeted information about its benefits and potential risks.

INTRODUCTION: Complementary and alternative medicine (CAM) is increasingly popular among cancer patients but can interfere with conventional therapies; timely data are needed to adapt current patients' care. MATERIALS AND METHODS: This transversal, prospective study evaluated the use of CAM among patients receiving adjuvant chemotherapy or endocrine therapy for early stage breast cancer. We assessed the prevalence of use, the motivations and predictive factors for use, as well as patients' information needs over a three months period. RESULTS: 69/184 responders (37.5%) reported using at least one CAM. CAM use was associated with younger age (p = 0.03) and higher education level (p < 0.001). Pharmacological substances (e.g., homeopathy, phytotherapy) were the most commonly used (79.7%) before physical means (42%) and dietary methods (31.9%). A total of 65.8% of users felt that these treatments have demonstrated evidence of efficacy and 74.8% that they were not associated with side effects. The main goal for use was improvement of treatment-related symptoms (28.3%); secondary goal was increasing the general health status (20.5%). Patients reported high needs for information on CAMs. CAM use was associated with mild differences in secondary adverse events reported by patients. CONCLUSION: Breast cancer patients are common users of CAM concomitantly to their conventional cancer treatments and should be investigated regarding their current consumption of CAM. Furthermore, they need advice evidence-based data on these treatments and potential interactions with on-going treatments.

PURPOSE/OBJECTIVES: To examine breast and ovarian cancer screening and risk-reducing behaviors of women seeking genetic cancer risk assessment (GCRA). DESIGN: Descriptive, cross-sectional. SETTING: An insurance-based clinic that serves high-risk patients in a southern California cancer center. SAMPLE: 134 women with breast or ovarian cancer (affected group) and 80 women with a family history of breast or ovarian cancer (unaffected group). The mean age of the sample was 48 years (range = 21-86), 79% were Caucasian, 66% were married, 60% were college educated, and 78% had children. Most affected women had early-stage disease. Unaffected women had a family history of breast (86%) or ovarian (14%) cancer. METHODS: Mailed surveys assessed pre-GCRA health behaviors and health and family histories. MAIN RESEARCH VARIABLES: Breast cancer screening (mammograms, clinical breast examination [CBE], breast self-examination), ovarian cancer screening (CA-125, pelvic ultrasound), and breast and ovarian cancer risk-reducing strategies (tamoxifen, bilateral mastectomy, oral contraceptive pills, bilateral salpingo-oophorectomy). FINDINGS: Twenty-one percent of the women who should have been having a mammogram had not had an annual examination as recommended, and 30% of affected women had not had annual CBEs. Few women took tamoxifen or oral contraceptive pills or had a bilateral salpingo-oophorectomy or bilateral mastectomy for cancer risk reduction. Twelve percent likely had unnecessary ovarian cancer screening. About 35% used other means, including herbs and homeopathy, for cancer prevention. CONCLUSIONS: Nearly a third of the affected women had not had appropriate breast cancer screening. About 12% used unsubstantiated, potentially harmful cancer "prevention" measures (e.g., herbs). IMPLICATIONS FOR NURSING: Nurses should assess clients' personal and family breast and ovarian cancer histories and promote cancer screening and risk-reducing behaviors that are appropriate for age and risk level.
