PURPOSE: Many patients with cytology proven node-positive breast cancer receive a neoadjuvant chemotherapy (NAC) treatment. We developed a nomogram to predict the breast and axillary pathologic complete responses (pCR) in patients with a cytologically proven axillary node positive breast cancer with NAC. METHODS: We selected 995 patients who were diagnosed with an invasive breast cancer and axillary lymph nodes metastasis, and who were treated with NAC followed by a curative surgery at the Samsung Medical Center between January 2007 and December 2014. The baseline patient and tumor characteristics, chemotherapy regimen, and tumor and nodal responses were thoroughly analyzed and reviewed. A nomogram was developed using a binary logistic regression model with a cross validation. RESULTS: Axillary pCR was achieved in 47.3% and breast pCR was achieved in 24.3% of the patients after NAC. In this case, the both pCR was associated with an initial clinical tumor stage, negative progesterone receptor status, positive human epidermal growth factor receptor 2 status, and clinical radiologic nodal responses. A nomogram was developed based on the clinical and statistically significant predictors. It had good discrimination performance (area under the curve [AUC], 0.868; 95% confidence interval, 0.84–0.89) and calibration fit as noted in that case. The cross validation had an average AUC 0.853 (0.837–0.869). CONCLUSION: Our nomogram might help to predict breast and axillary pCRs after NAC in patients with an initially node-positive breast cancer. Minimal surgery might be acceptable in patients for whom the nomogram indicates a high probability of achieving pCRs.

PURPOSE: This study aimed to develop and test a structural model for chemotherapy-related cognitive impairment of breast cancer patients based on a literature review and Hess and Insel's chemotherapy-related cognitive change model. METHODS: The Participants consisted of 250 patients who were ≥19 years of age. The assessment tools included the Menopause Rating Scale, Symptom Experience Scale, Hospital Anxiety and Depression Scale, Everyday Cognition, and Functional Assessment of Cancer Therapy-Breast Cancer. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs. RESULTS: The modified model was a good fit for the data. The model fit indices were χ2=423.18 (p<.001), χ2/df=3.38, CFI=.91, NFI=.91, TLI=.89, SRMR=.05, RMSEA=.09, and AIC=515.18. Chemotherapy-related cognitive impairment was directly influenced by menopausal symptoms (β=.38, p=.002), depression and anxiety (β=.25, p=.002), and symptom experiences (β=.19, p=.012). These predictors explained 47.7% of the variance in chemotherapy-related cognitive impairment. Depression and anxiety mediated the relations among menopausal symptoms, symptom experiences, and with chemotherapy related cognitive impairment. Depression and anxiety (β=−.51, p=.001), symptom experiences (β=−.27, p=.001), menopausal symptoms (β=−.22, p=.008), and chemotherapy-related cognitive impairment (β=−.15, p=.024) had direct effects on the quality of life and these variables explained 91.3%. CONCLUSION: These results suggest that chemotherapy-related toxicity is highly associated with cognitive decline and quality of life in women with breast cancer. Depression and anxiety increased vulnerability to cognitive impairment after chemotherapy. Nursing intervention is needed to relieve chemotherapy-related toxicity and psychological factor as well as cognitive decline for quality of life in patients undergoing chemotherapy.

To investigate the effect of the aroma therapy and music intervention on anxious and pain for the breast cancer patients in the perioperative period and the potential mechanisms.
 Methods: A total of 100 breast cancer patients who received surgical treatment in the comprehensive hospitals of Hunan province were recruited for this study. Patients were assigned randomly into a control group, an aroma therapy group, a music intervention group, and a joint-therapy group (n=25 per group). The patients in the control group received regular post-surgical nursery, while the patients from other groups received aroma therapy, music intervention, or both in addition to the regular nursery. The scale of anxiety and pain were measured. The measurements were carried at three time points, namely 30 min before the surgery (T1), 30 min after the recovery period of anesthesia (T2), and 4 hours after the removal of anesthesia tubing (T3). Repeated ANOVA was used to perform statistic analysis.
 Results: The scale of pain was significantly increased at the post-operation (T2, T3) compared to pre-surgery (T1). The therapeutic group showed significant decrease in pain at post-operation (T3) comparing with the control group (P<0.05). The scale of anxiety was the highest at pre-surgery (T1). During anaesthesia recovery, the anxiety of patients at post-operation T2 and T3 in the therapeutic groups significantly decreased compared with the control group (P<0.05).
 Conclusion: Both the aroma therapy and the music therapy can decrease the stress-responsive anxiety and pain for the breast cancer patients in the perioperative period.

OBJECTIVES: Cognitive complaints are reported frequently after breast cancer treatments. The causes of cognitive decline are multifactorial, a result of the effect of cancer itself, chemotherapy, and psychological factors such as depression and anxiety. However, cognitive decline does not always correlate with neuropsychological test performance. The purpose of this study was to examine the relationship of subjective cognitive decline with objective measurement and to explore associated factors of cognitive function in breast cancer survivors. METHODS: We included 29 breast cancer survivors who complain cognitive decline at least 6 months after treatment and 20 age-matched healthy controls. Neuropsychological tests were performed in all participants. Multivariable regression analysis evaluated associations between neuropsychological test scores and psychological distress including depression and anxiety, also considering age, education, and comorbidity. RESULTS: There were no statistically significant differences in neuropsychological test performances. However, the breast cancer survivors showed a significantly higher depression(p=0.002) and anxiety(p < 0.001) than the healthy controls did. Among the cancer survivors, poorer executive function was strongly associated with higher depression(β=−0.336, p=0.001) and anxiety(β=−0.273, p=0.009), after controlling for age, education, and comorbidity. In addition, poorer attention was also significantly related with depression(β=−0.375, p=0.023) and anxiety (β=−0.404, p=0.013). CONCLUSIONS: The results of this study showed the discrepancies between subjective complaints and objective measures of cognitive function in breast cancer survivors. It suggests that subjective cognitive decline could be indicators of psychological distress such as depression and anxiety.

PURPOSE: The purpose of this study was to identify the degree of menopause symptoms and associated factors in patients with breast cancer who were receiving hormone therapy. METHODS: Data were collected with questionnaires from 150 patients with breast cancer who had been on hormone therapy at a hospital in Seoul. Data were analyzed with the t-test, ANOVA, and Pearson correlation coefficient to compare the degree of menopause symptoms by demographic, clinical and psychological factors. RESULTS: The mean menopause symptoms score was 13.39±7.97. Most participants reported having hot flushes and sweating (75.3%), physical and mental exhaustion (82.7%) and sexual problems (64.7%). Menopause symptoms and depression were correlated with each other (p < .01). Somato-vegetative symptoms were different significantly by age, menopausal status at time of operation, occupation and tumor. Psychological symptoms were different significantly by marital status, operation type and chemotherapy. Urogenital symptoms were different significantly by prior history of cancer, occupation, operation type and radiation therapy. CONCLUSION: These findings can be used to provide tailored nursing interventions by identifying high risk groups for menopausal symptom among breast cancer patients receiving hormone therapy.

PURPOSE: The purpose of this study was to develop and preliminarily evaluate the reliability and validity of the Symptom-Management Self-Efficacy ScaleeBreast Cancer (SMSES-BC) related to chemotherapy. METHODS: The study included three stages. This paper presents the results of stage 2 and stage 3. In total, 34 items in the SMSES-BC were found during stage 1 from qualitative findings, a literature review, and expert suggestions; the 34 items were used for the psychometric properties test. Test-retest reliability and Cronbach alpha were assessed in the first sample, which included 45 participants for the pilot test (stage 2). The second sample, which included 152 patients, was used to assess the construct validity and concurrent validity (stage 3). RESULTS: The pilot test results revealed a test-retest reliability of .73 (p < .001) and Cronbach alpha coefficient of .96 for the total scale. Three factors (managing chemotherapy-related symptoms, acquiring problem solving, and managing emotional and interpersonal disturbances) were identified from exploratory factor analysis. Correlation coefficient r was .40 (p < .001), which supported the association between SMSES-BC and the General Self-Efficacy Scale for concurrent validity. CONCLUSIONS: The study results demonstrate acceptable reliability and validity for the SMSES-BC that was developed for measuring symptom-management self-efficacy related to chemotherapy for patients with breast cancer. This study suggests further research to validate the construct of the SMSES-BC.

PURPOSE: The purpose of this study was to develop a scale to evaluate empowerment in woman with breast cancer and to examine the validity and reliability of the scale. METHODS: The development process for the initial items included a literature review, interviews, and construction of a conceptual framework. The identified items were evaluated for content validity by experts, resulting in 3 factors and 48 preliminary items. Participants were 319 women with breast cancer recruited to test reliability and validity of the preliminary scale. Data were analyzed using item analysis, confirmatory factor analysis, criterion related validity, internal consistency and test-retest reliability. RESULTS: The final scale consisted of 30 items and 3 factors. Factors, including 'intrapersonal factor' (14 items), 'interactional factor' (8 items), and 'behavioral factor' (8 items), were drawn up after confirmatory factor analysis. Goodness of fit of the final research model was very appropriate as shown by chi2/df=1.86, TLI=.90, CFI=.92, SRMR=.06, and RMSEA=.05. Criterion validity was evaluated by total correlation with the Cancer Empowerment Questionnaire .78. Cronbach's alpha for total items was .93 and test-retest reliability was .69. CONCLUSION: Findings from this study indicate that the scale can be used in the development of nursing interventions to promote the empowerment of women having breast cancer.

PURPOSE: The purpose of the study was to identify degrees of pain, menopause symptoms, and quality of life, and to identify factors influencing quality of life of patients with breast cancer who were on hormone therapy. METHODS: A cross-sectional survey design was utilized. Data were collected using questionnaires from 110 patients with breast cancer who had been on hormone therapy for 3 months or more and were being treated at a university hospital in Seoul. Data were analyzed using chi2-test, t-test, ANOVA, Pearson correlation coefficient and multiple linear regression. RESULTS: Mean age of the participants was 53.56 (SD=6.67) and 54 (51.4%) had stage 0 or I at the time of diagnosis. Most of the participants reported having pain and menopause symptoms (88.2% and 95.5% respectively). The mean score for quality of life was 87.84+/-21.17. Pain, menopause symptoms and quality of life had strong correlations with each other (p<.005). Quality of life was explained by menopause symptoms (beta= -.71), economic status (beta=.20) and occupation (beta=.16). CONCLUSION: The results of the study suggest that menopause symptoms should be incorporated into oncologic nursing care to improve quality of life of patients with breast cancer on hormone therapy.

PURPOSE: This study was done to propose a structural model to explain and predict psychosocial adjustment in patients with early breast cancer and to test the model. The model was based on the Stress-Coping Model of Lazarus and Folkman (1984). METHODS: Data were collected from February 18 to March 18, 2009. For data analysis, 198 data sets were analyzed using SPSS/WIN12 and AMOS 7.0 version. RESULTS: Social support, uncertainty, symptom experience, and coping had statistically significant direct, indirect and total effects on psychosocial adjustment, and optimism had significant indirect and total effects on psychosocial adjustment. These variables explained 57% of total variance of the psychosocial adjustment in patients with early breast cancer. CONCLUSION: The results of the study indicate a need to enhance psychosocial adjustment of patients with early breast cancer by providing detailed structured information and various symptom alleviation programs to reduce perceived stresses such as uncertainty and symptom experience. They also suggest the need to establish support systems through participation of medical personnel and families in such programs, and to apply interventions strengthening coping methods to give the patients positive and optimistic beliefs.

OBJECTIVE: To explore the relationship between the demand in breast cancer patients during hospitalization and the affective factors. METHODS: A self-developed " breast cancer patients demand questionnaire" was used in 115 breast cancer patients in hospital, and multiple linear regression was used to analysis of the impacts of each domains and total scores. RESULTS: The average score in domain of disease knowledge is highest, about 3.77. The total score,physiological score, social psychological need score in patients during operation are higher than those in patients during chemotherapy,the scores were 140.07, 31.82, 59.57 and 126.38, 28.87, 51.64,respectively. The total scores were effected by the type of pathology and education levels. In addition, the demands also were related with the type of surgery, treatment stage, family structure and family economic income. CONCLUSION The demand in breast cancer patients during hospitalization includes the disease knowledge, physiological, social psychological need. Different individualized intervention should be taken in the difference patients.
