Purpose: The aim of this study was to investigate the current state of antidepressant prescriptions in breast cancer patients and factors affecting the prescription of antidepressants. Methods: This study targeted female breast cancer patients who were prescribed antidepressants by a psychiatrist at least once between August 2010 and July 2011 at the Asan Medical Center in Seoul. The prescription history of each study subject was investigated to analyze the current state of antidepressant prescriptions in breast cancer patients. Results: The analysis of the prescription histories of 136 subjects in the antidepressant group determined that escitalopram, mirtazapine, and trazodone were the three most commonly prescribed medications with an average of 1.54 antidepressants prescribed per patient. A logistic regression analysis showed a statistically significant increase in antidepressant prescriptions in patients who were divorced or widowed, had sleep disturbances, or had undergone oncologic surgery for the breast cancer (p<0.050). In contrast, the prescription rate was lower for patients with tumour sizes greater than 50 mm (p<0.050). Conclusion: The sociodemographic factor of marital status, clinical factors of sleep disorders and tumour size, and a treatment-specific factor of the use of surgical therapy were identified as affecting the prescription of antidepressants in female breast cancer patients.

Among the treatment options for BRCA mutation carriers, risk reducing surgery is the most effective. However, this procedure has been rarely performed in Korea. Interestingly, our case showed double heterozygosity for BRCA1 and BRCA2 mutations. The patient was diagnosed with left renal cancer and left breast cancer at 45-years-of-age, 4 years before risk reducing surgery. The patient received left radical nephrectomy and left partial mastectomy with axillary lymph node dissection. After pretest counseling, the patient underwent genetic testing that identified BRCA1 and BRCA2 mutations. After post-test counseling, the patient decided on intensive surveillance. At 49-years-of-age, the patient was newly diagnosed with contralateral breast cancer. Treatment options were discussed once again. We performed bilateral total mastectomy with immediate reconstruction and prophylactic bilateral salpingo-oophorectomy after multidisciplinary discussion. The patient has been satisfied with the results of surgery. We think this procedure is a recommendable treatment option for BRCA mutation carriers.

Background: Breast cancer is the most common malignancy in women worldwide and its incidence is generally increasing. In 2012, it was the second most common cancer in the world. It is necessary to obtain information on incidence and mortality for health planning. This study aimed to investigate the relationship between the human development index (HDI), and the incidence and mortality rates of breast cancer in the world in 2012. Materials and Methods: This ecologic study concerns incidence rate and standardized mortality rates of the cancer from GLOBOCAN in 2012, and HDI and its components extracted from the global bank site. Data were analyzed using correlation tests and regression with SPSS software (version 15). Results: Among the six regions of WHO, the highest breast cancer incidence rate (67.6) was observed in the PAHO, and the lowest incidence rate was 27.8 for SEARO. There was a direct, strong, and meaningful correlation between the standardized incidence rate and HDI (r=0.725, $p{\leq}0.001$). Pearson correlation test showed that there was a significant correlation between age-specific incidence rate (ASIR) and components of the HDI (life expectancy at birth, mean years of schooling, and GNP). On the other, a non-significant relationship was observed between ASIR and HDI overall (r=0.091, p=0.241). In total, a significant relationship was not found between age-specific mortality rate (ASMR) and components of HDI. Conclusions: Significant positive correlations exist between ASIR and components of the HDI. Socioeconomic status is directly related to the stage of the cancer and patient's survival. With increasing the incidence rate of the cancer, mortality rate from the cancer does not necessariloy increase. This may be due to more early detection and treatment in developed that developing countries. It is necessary to increase awareness of risk factors and early detection in the latter.

Objectives: This study was conducted to identify the relationship among knowledge, self-efficacy and compliance behavior on breast self examination(BSE) of female college students'. Methods: This descriptive study was conducted with a convenient sample of 499 female college student. Surveyed data collected from May to August 2008 were analyzed using descriptive statistics, t-test, pearson correlation coefficients and stepwise multiple regression. Results: The mean score of knowledge and self-efficacy concerning BSE was low, and compliance was high. The levels of knowledge, self-efficacy and compliance were differed significantly by experience of thinking about breast cancer, perceived susceptibility of breast cancer, experience of meeting with breast cancer patient, and educational experience of BSE. Significant correlations were found between knowledge and compliance, knowledge and compliance, knowledge and self-efficacy. Knowledge and self-efficacy were a powerful predictor of compliance. Conclusion: Focus on perceived knowledge, self-efficacy about breast self examination(BSE) of female college students may be beneficial to improve compliance, and should be reflected in the development of effective BSE education program.

Currently, state-of-the-art devices such as SPECT, PET/CT, and PET/MRI are rapidly spreading nationwide, and the penetration rate of nuclear medical devices is also ranked fifth in the world. However, PET/MRI's system is slower and less common because it is more complex than PET/CT. The purpose of this study is to provide optimal information on PET/MRI according to the patient's disease. The subjects obtained information on head and neck cancer, pediatric patients, breast cancer patients, heart disease patients, lung cancer patients, and rectal cancer patients. We tried to accumulate protocols by obtaining a lot of information about each disease. In diagnosing head and neck cancer, it is believed that it is highly likely to be used in evaluating preoperative stage determination, recurrence and remote metastasis after treatment, and unclear primary cervical lymph node metastasis. Diagnosis and continuous follow-up of pediatric patients can increase patient benefits by minimizing radiation exposure. Breast cancer provides a comprehensive evaluation of the clinical need to determine the extent of disease in breast and local lymph nodes and the systematic stages of early diagnosis or recurrence. In diagnosing heart disease patients, MR-based PET motion correction helps to realize the full potential of PET images. For lung cancer patients, the clinical value and usefulness of the resolution and detection ability of integrated PET/MRI for soft tissues such as lung cancer will be sufficient. In diagnosing rectal cancer patients, the detection of missing residual diseases can change the clinical response evaluation for rectal cancer patients treated with TNT, and both the initial stage and treatment response evaluation are possible. Therefore, this literature study provided basic clinical data for PET/MRI tests.

Background Nipple-areolar complex (NAC) reconstruction following curative mastectomy is traditionally performed as a second-stage procedure several months after initial breast reconstruction. The recent literature has documented the increasing popularity of immediate nipple reconstruction carried out simultaneously during autologous reconstruction. The aim of this study was to evaluate the surgical outcomes and patient satisfaction with immediate breast and nipple reconstruction performed in a single stage after skin-sparing mastectomy. Methods All patients who underwent a skin-sparing mastectomy with immediate latissimus dorsi flap breast and NAC reconstruction as a single-stage procedure from 2007 to 2015 were included. Patient demographics, oncologic details, and surgical outcomes were recorded. The BREAST-Q questionnaire was administered to patients to assess the impact and effectiveness of this reconstructive strategy. Results During the study period, 34 breast and NAC reconstructions in 29 patients were performed at Cork University Hospital. The majority of our patient cohort were non-smokers (93.1%) and did not receive adjuvant radiotherapy. Postoperative complications were infrequent, with no cases of partial necrosis or complete loss of the nipple. The response rate to the BREAST-Q was 62% (n=18). Patients reported high levels of satisfaction with the reconstructed breast ($62{\pm}4$), nipple reconstruction ($61{\pm}4.8$), overall outcome ($74.3{\pm}5$), and psychosocial well-being ($77.7{\pm}3.2$). Conclusions Skin-sparing mastectomy with immediate nipple reconstruction during autologous latissimus dorsi reconstruction was demonstrated to be a safe and aesthetically reliable procedure in our cohort, yielding high levels of psychological and physical well-being. A single-stage procedure promotes psychosocial well-being involving issues that are intrinsically linked with breast cancer surgery.

Purpose: We aimed to study the inflammatory parameters of complete blood count in breast cancer cases. Materials and Methods: This retrospective study covered 178 breast cancer patients and 107 age and body mass index matched healthy women. Complete blood count parameters, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and MPV/platelet were analyzed. Results: The leukocyte, neutrophil and neutrophil/lymphocyte ratio were higher in the patient group (p values 0.001, 0.0001 and 0.0001, respectively) while haemoglobin and hematocrit were higher in the control group (p=0.0001 for both). Logistic regression analysis showed that elevated neutrophils and platelet distribution width (PDW) (OR: 0.627, 95%CI: 0.508-0.774, p=0.001 and OR: 1.191 95%CI: 1.057-1.342 p=0.003) were independent variables for predicting breast cancer. The cut-off value for the neutrophil/lymphocyte ratio was 2.56. Conclusions: According to our study results, neutrophil levels as part of complete blood count may be used as an independent predictor of breast cancer risk.

Introduction: Trastuzumab, an HER2-targeting agents, has shown efficacy in metastatic HER2-positive breast cancer patients. Single-agent clinical trials have evaluated therapeutic regimens using trastuzumab for metastatic breast cancer patients. The aim of our study is to evaluate the efficacy and safety of trastuzumab in combination with chemotherapy or hormone therapy in HER2-positive metastatic breast cancer patients. Methods: A literature research was conducted in PubMed and to identify appropriate studies from relevant reviews. Randomized controlled trials comparing chemotherapy or hormone therapy regimens in combination with trastuzumab were eligible. Dadta on clinical outcomes, including safety, efficacy, and patient characteristics were collected. Results: Seven articles describing five trials were included in our systematic review and meta-analysis. Partners of trastuzumab included in trials were anthracycline, paclitaxel, docetaxel, anastrozole and letrozole. The addition of trastuzumab to chemotherapy improved the overall survival (HR=0.79, 95%CI 0.65-0.96), while to hormone therapy did not (HR=0.85 95%CI 0.56-1.30). All trastuzumab-containing regimens increased cardiac toxicity (RR=3.37, 95%CI 1.26-9.02) and grade III-IV adverse events. Conclusions: Our study supports the addition of trastuzumab to chemotherapy which is effective and tolerated for metastatic breast cancer with HER2+ patients. Of note, more adverse events will occur followed the use of trastuzumab, especially cardiac toxicity, with two treatment regimens.

The aims of this study were to assess whether Indonesian women with breast cancer havea higher external health locus of control (HLC) than healthy women, and to explore the association between HLC and symptoms of anxiety and depression. In this study, 120 consecutive women with breast cancer were recruited at the outpatient surgical oncology clinic at the Hasan Sadikin Hospital in Bandung. One hundred and twenty two healthy women were recruited from the Bandung area as controls. A standard demographic form, Form C of the Multidimensional Health Locus of Control, as well as the Hospital Anxiety and Depression Scale and patients' medical records were used. Data were analyzed using descriptive statistics, t-test, Pearson's correlation, MANOVA and multiple linear regressions. Women with breast cancer had higher scores on all external HLC subscales, i.e. chance, doctor, powerful others and God, and lower internal HLC compared to healthy women. High God LHC scores were associated with a high level of anxiety (${\beta}=0.21$, p<0.05), whereas none of the HLC subscales were associated with depression. Our results suggest that women with breast cancer tend to have high external HLC, while healthy women tend to have high internal HLC. A strong belief in an external source of control, i.e. God, might be negatively associated with patient emotional adjustment. Further research is needed to give an insight into the direction of this association.

We used to LASSO-Cox method for determining prognostic factors of male breast cancer survival and showed the superiority of this method compared to Cox proportional hazard model in low sample size setting. In order to identify and estimate exactly the relative hazard of the most important factors effective for the survival duration of male breast cancer, the LASSO-Cox method has been used. Our data includes the information of male breast cancer patients in Fars province, south of Iran, from 1989 to 2008. Cox proportional hazard and LASSO-Cox models were fitted for 20 classified variables. To reduce the impact of missing data, the multiple imputation method was used 20 times through the Markov chain Mont Carlo method and the results were combined with Rubin's rules. In 50 patients, the age at diagnosis was 59.6 (SD=12.8) years with a minimum of 34 and maximum of 84 years and the mean of survival time was 62 months. Three, 5 and 10 year survival were 92%, 77% and 26%, respectively. Using the LASSO-Cox method led to eliminating 8 low effect variables and also decreased the standard error by 2.5 to 7 times. The relative efficiency of LASSO-Cox method compared with the Cox proportional hazard method was calculated as 22.39. The19 years follow of male breast cancer patients show that the age, having a history of alcohol use, nipple discharge, laterality, histological grade and duration of symptoms were the most important variables that have played an effective role in the patient's survival. In such situations, estimating the coefficients by LASSO-Cox method will be more efficient than the Cox's proportional hazard method.
