RESUMEN
Purpose@#Neoadjuvant chemotherapy (NAC) can effectively downstage locally advanced breast cancer; however, in some cases the cancer remains clinically stable and in others, there is disease progression. Although factors predictive of the response to NAC have been established, those for a non-response remain unknown. This study investigated factors predicting a stable or progressive disease course, and the extent of the response, after NAC based on anthracycline and cyclophosphamide (AC), with or without taxane. @*Methods@#Data were collected retrospectively by reviewing medical records of patients who received NAC for breast cancer using AC, with or without taxane between January 2013 and December 2017. Patients with clinically stable or progressive disease after NAC were compared statistically with those who achieved a partial or complete response. @*Results@#In total, 297 patients received NAC with AC and 196 patients received AC followed by taxane. Of these, 45 (15.2%) and 64 (32.6%) patients respectively, showed no response (i.e., stable or progressive disease). Factors related to non-response after AC included large pretreatment tumor size, clinical T3 status, and high histologic grade. Factors related to non-response after taxane included clinical T3 status and estrogen receptor or progesterone receptor positivity. @*Conclusion@#Clinical T3 stage, grade III histological grade, and estrogen or progesterone receptor positivity were predictors of no response to NAC for breast cancer.
RESUMEN
PURPOSE: The aim of this study was to evaluate the severity of menopausal symptoms and their impact on the quality of life (QOL) in breast cancer patients with chemotherapy-induced amenorrhea. METHODS: A cross-sectional survey design was used. Participants were 112 breast cancer patients with chemotherapy-induced amenorrhea. They completed the Menopause Rating Scale (MRS) and the Functional Assessment of Cancer Therapy-General (FACT-G). Data were analyzed using descriptive statistics, independent t-tests, one-way ANOVA, Pearson's correlation coefficients, and multiple regression with SPSS/WIN 23.0. RESULTS: The prevalence of symptoms among the participants were as follows: sleep problems, 88.4%; physical and mental exhaustion, 80.4%; joint and muscular discomfort, 76.8%; and depression, 70.5%. Menopausal symptoms had a significant negative association with QOL. The results of the regression analysis showed that psychological and urogenital symptoms were statistically significant in explaining patients' QOL and accounted for 70% of the total variance. CONCLUSION: Menopausal symptoms appear to be a significant problem for premenopausal breast cancer patients. Assessment and control of menopausal symptoms played a large role in maintaining the quality of life in breast cancer patients.
RESUMEN
PURPOSE: The purpose of this study was to examine the effects of integrated psychoeducational program for distress management of newly diagnosed patients with breast cancer. METHODS: A quasi-experimental trial was conducted. The participants consisted of 47 female patients with breast cancer assigned to an intervention group (n=25) and control group (n=22). The intervention group participated in integrated psychoeducational program, consisting of individual face-to-face education and telephone-delivered health-coaching sessions. Data were collected at three time points: pre-intervention (T1), post-intervention (T2), and 6-month follow-up (T3). Study instruments were Distress thermometer, Supportive Care Needs Survey Short Form 34 and Functional Assessment of Cancer Therapy-Breast. RESULTS: Compared with the control group, breast cancer patients in the intervention group reported lower distress and supportive care needs than the control group. The intervention group reported higher quality of life (QOL) overall and higher emotional well-being than the control group. CONCLUSION: These findings indicate that the integrated psychoeducational program is an effective intervention for reducing distress and supportive care needs and increasing QOL of newly diagnosed patients with breast cancer. Oncology nurses need to provide psychoeducational intervention to support patients with breast cancer in managing their distress and helping them adjust to their life.

PURPOSE: Psychological distress is a significant and ongoing problem for breast cancer. These mental health problems are often neglected as they are not always properly understood. This study was performed to explore the trajectory of psychological distress over 1 year since breast cancer surgery and to identify the associated factors for the trajectory. METHODS: One hundred seventeen women who underwent surgery for breast cancer completed the psychological distress thermometer and problem lists from after surgery to 12 months after surgery. Information on their sociodemographic and clinical characteristics was also obtained. Group-based trajectory modeling was performed to identify the distinct trajectories of psychological distress. Chisquare test and logistic regression analysis were performed to determine predictors of psychological distress trajectories. RESULTS: two-group linear trajectory model was optimal for modeling psychological distress (Bayesian information criterion = −777.41). Group-based trajectory modeling identified consistently high-distress (19.4%) and low-decreasing distress (80.6%) trajectories. Old age, depression, nervousness, and pain were significant predictors of consistently high-distress trajectory. CONCLUSION: Our results indicate that distinct trajectory groups can be used as a screening tool to identify patients who may be at an increased risk of psychological distress over time. Screening for psychological distress during disease diagnosis is important and necessary to identify patients who are at an increased risk of elevated distress or at risk of experiencing psychological distress over time.

PURPOSE: The effects of biological subtypes within breast cancer on prognosis are influenced by age at diagnosis. We investigated the association of young age with locoregional recurrence (LRR) between patients with luminal subtypes versus those with nonluminal subtypes. MATERIALS AND METHODS: Medical records of 524 breast cancer patients with positive lymph nodes between 1999 and 2010 were reviewed retrospectively. All patients received curative surgery and adjuvant chemotherapy based on contemporary guidelines. Radiation was delivered for patients who underwent breast conserving surgery or those who had four or more positive lymph nodes after mastectomy. Adjuvant hormone therapy was administered to 413 patients with positive hormone receptors according to their menstrual status. RESULTS: During median follow-up of 84 months, the 10-year locoregional recurrence-free survival rate (LRRFS) was 84.3% for all patients. Patients < 40 years showed significantly worse 10-year LRRFS than those ≥ 40 years (73.2% vs. 89.0%, respectively; p=0.01). The negative effect of young age on LRRFS was only observed in luminal subtypes (69.7% for < 40 years vs. 90.8% for ≥ 40 years; p < 0.01). Multivariate analysis using luminal subtypes ≥ 40 years as a reference revealed luminal subtypes < 40 years were significantly associated with increased risk of LRR (hazard ratio, 2.33; p < 0.01). CONCLUSION: Young breast cancer patients with positive lymph nodes had a higher risk of LRR than those aged ≥ 40 years. This detrimental effect of young age on LRR was confined in luminal subtypes.

Lymphedema is a condition characterized by tissue swelling caused by localized fluid retention. Advanced lymphedema is characterized by irreversible skin fibrosis (stage IIIb) and nonpitting edema, with leather-like skin, skin crypts, and ulcers with or without involvement of the toes (stage IVa and IVb, respectively). Recently, surgical treatment of advanced lymphedema has been a challenging reconstructive modality. Microvascular techniques such as lymphaticovenous anastomosis and vascularized lymph node flap transfer are effective for early stage lymphedema. In this study, we performed a two-stage operation in an advanced lymphedema patient. First, a debulking procedure was performed using liposuction. A vascularized free lymph node flap transfer was then conducted 10 weeks after the first operation. In this case, good results were obtained, with reduced circumferences in various parts of the upper extremity noted immediately postoperation.

PURPOSE: The purpose of this study was to identify changes of supportive care needs and relationship to quality of life (QOL) in patients with breast cancer. METHODS: 117 patients with breast cancer were administered the Supportive Care Needs Survey-Short form 34 and the Functional Assessment of Cancer Therapy-Breast before adjuvant therapy after mastectomy (T1), at the end of completing adjuvant therapy (T2), as well as 6 months after the completion of adjuvant therapy (T3). Data were analyzed using SPSS/Win 21.0. RESULTS: The highest unmet supportive care needs were observed in the health system and information domain and the psychological domain at each time point. The health system and information (F=22.49, p<.001) and physical and daily living needs (F=5.72, p=.004) were higher at T1 and T2 than T3. The psychological (F=7.43, p=.001) and patient care and support needs were higher at T1 than T2 and T3. Multiple regression analysis showed that breast cancer patients with greater physical and daily living and psychological needs were significantly associated with poorer QOL at all times. CONCLUSION: Supportive care should be timely provided to breast cancer patients to improve their ability to cope with physical and psychological problem and QOL. Breast cancer patients who had more unmet needs in psychological and physical domains were more likely to have a poor QOL.

PURPOSE: Posttraumatic growth (PTG) is defined as 'positive psychological change experienced as a result of a struggle with highly challenging life circumstances'. The purpose of this study was to identify the level of PTG and its correlates in Korean patients with breast cancer. METHODS: A sample of 120 participants was recruited from outpatients, who had successfully completed primary treatment of breast cancer at a university hospital., Data were collected from June to December, 2014 using Posttraumatic Growth Inventory, lllness Intrusiveness Rating Scale, Cancer Coping Questionnaire, Revised Life Orientation Test and The Multidimensional Scale of Perceived Social Support. RESULTS: Total score for the PTG was 79.18±17.54 in patients surviving breast cancer. Bivariate analyses indicated that PTG was positively associated with having a religion, perceived social support, greater optimism, cancer coping, and illness intrusiveness. Results of the regression analysis showed that cancer coping (β=.29, p=.001), optimism (β=0.28, p=.001) and illness intrusiveness (β=0.17, p=.037) were statistically significant in patients' PTG. CONCLUSION: The research findings show that the variables of cancer coping, optimism and illness intrusiveness significantly explain PTG and these psychological variables can be used to provide improvement in PTG for patients with breast cancer

PURPOSE: Evidence suggests that some patients with breast cancer experience cognitive difficulties following chemotherapy. This longitudinal study was done to examine the prevalence of cognitive impairment and trajectory of cognitive function over time in women with breast cancer, who received adjuvant chemotherapy. METHODS: Participants were 137 patients with breast cancer. They completed neuropsychological tests and the Functional Assessment of Cancer Therapy-Cognitive Function before adjuvant therapy (pretest), toward the end of adjuvant therapy (posttest), and 6 months after the completion of adjuvant therapy (follow-up test). Of the patients, 91 were treated with adjuvant chemotherapy and 46 patients who did not receive chemotherapy made up the comparison group. A reliable-change index and repeated-measure ANOVA were used for statistical analyses. RESULTS: At the posttest point, over 30% of patients showed complex cognitive impairment and reported greater difficulty in subjective cognitive function. At the follow-up test point, 22.0% of patients exhibited complex cognitive impairment and 30.8% of patients complained of subjective cognitive impairment. Repeated-measure ANOVA showed significant decreases after receiving chemotherapy followed by small improvements 6 months after the completion of chemotherapy in cognitive domains of change for attention and concentration, memory, executive function, and subjective cognitive function. CONCLUSION: These results suggest that chemotherapy in patients with breast cancer may be associated with objective and subjective cognitive impairments. Further studies are needed to explore the potential risk factors and predictor of chemotherapy-related cognitive changes. Also nursing interventions for prevention and intervention of cognitive impairments should be developed and tested.

PURPOSE: The purpose of this study was to determine the prevalence of distress and to investigate the related problems in breast cancer patients at the end of primary treatment. METHODS: A sample of 118 participants was recruited among outpatients who had successfully completed primary treatment of breast cancer. Data were collected between July, 2013 and October, 2014 using the Distress Thermometer (DT) scale and problem lists. Descriptive statistics and logistic regression analysis were used to analyze data. RESULTS: Among the 118 patients that participated in this study, 34 patients (28.8%) suffered from elevated distress using the previously validated cut point > or =4 for the DT. Problems most frequently encountered were fatigue (68.8%), worry (59.3%), appearance (51.7%) and memory/concentration (48.3%). Multivariate logistic regression analysis revealed that depression (OR=9.55), worry (OR=8.34), fatigue (OR=8.19) and age (OR=1.14) were independent predictors for elevated distress scores. CONCLUSION: Utilizing the DT, onethird of breast cancer patients screened met criteria for distress at the end of the primary treatment. Breast cancer patients with depression, worry, fatigue and older age should be targeted for distress screening and management.

PURPOSE: Neoadjuvant chemotherapy is the standard treatment for patients with locally advanced breast cancer and is increasingly considered for patients with operable disease. Recently, as many clinical trials have demonstrated favorable outcomes of anthracycline-taxane based regimen, this approach has been widely used in the neoadjuvant setting. METHODS: We compared women who received adriamycine and docetaxel (AD) with adriamycin, cyclophosphamide followed by paclitaxel (AC-T) as neoadjuvant chemotherapy. The AD group was scheduled for six cycles of AD (50 mg/m2 and 75 mg/m2, respectively) at a 3-week interval. The AC-T group was scheduled for four cycles of adriamycin and cyclophosphamide (50 mg/m2 and 500 mg/m2, respectively) followed by four cycles of paclitaxel (175 mg/m2) at a 3-week interval. RESULTS: The responses of chemotherapy were equivalent (overall response rate [AD, 75.7% vs. AC-T, 80.9%; P = 0.566], pathologic complete response [pCR] rate [breast and axilla: AD, 10.8% vs. AC-T, 12.8%; P = 1.000; breast only: AD, 18.9% vs. AC-T, 14.9%, P = 0.623], breast conserving surgery rate [P = 0.487], and breast conserving surgery conversion rate [P = 0.562]). The pCR rate in the breast was higher in the human epidermal growth factor receptor 2 (HER2) positive cases (HER2 positive 33.3% vs. negative 10%, P = 0.002). Although nonhematologic toxicities were comparable, hematologic toxicities were more severe in the AD group. Most women in the AD group suffered from grade 3/4 neutropenia (P < 0.001) and neutropenic fever (P < 0.001). CONCLUSION: Tumor responses were not different in various variables between the two groups. However, AC-T was a more tolerable regimen than AD in patients with breast cancer receiving neoadjuvant chemotherapy.

Granulocytic sarcoma is a localized extramedullary solid tumor composed of immature myeloid cell and is usually associated with acute myeloid leukemia or myelodysplastic syndrome. Although it can involve any site, commonly in lymph nodes, skin, bone and soft tissue, the involvement of breast is unusual. Especially, the involvement of the breast as a pattern of relapse after bone marrow transplantation is extremely rare. We have experienced 2 cases of granulocytic sarcoma after bone marrow transplantation. One case was a 39-year-old woman with right breast mass diagnosed with granulocytic sarcoma. She had received an unrelated bone marrow transplantation due to biphenotype acute leukemia 3 years before our presentation. Another case was a 48-year-old woman with acute myeloid leukemia, who was diagnosed with granulocytic sarcoma on both breasts 8 months after allogenic bone marrow transplantation. We also discuss the clinicopathologic features of granulocytic sarcoma in breast after bone marrow transplantation.

RESUMEN
PURPOSE: Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory disease of unknown etiology. The diagnosis of IGM requires that other granulomatous lesions in the breast be excluded. Tuberculous mastitis (TM) is also an uncommon disease that is often difficult to differentiate from IGM. The purpose of this study is to develop a new algorithm for the differential diagnosis and treatment of IGM and TM. METHODS: Medical records of 68 patients (58 with IGM and 10 with TM) between July 1999 and February 2009 were retrospectively reviewed. RESULTS: The mean age of the patients was 33.5 (IGM) and 40 (TM) years (p=0.018). The median follow-up was 84 months. Of the total 10 patients with TM, 5 patients had a history of pulmonary tuberculosis. The most common symptoms of the diseases were breast lump and pain. However, axillary lymphadenopathy was more seen in TM (50%) compared to IGM (20.6%) (p=0.048). TM showed more cancer-mimicking findings on radiologic study (p=0.028). In IGM, 48 patients (82.7%) underwent surgical wide excision and 21 patients (36.2%) were managed with corticosteroid therapy and antibiotics. All of the TM patients received anti-tuberculosis medications and 9 patients (90%) underwent wide excision. The mean treatment duration was 2.8 months in IGM and 8.4 months in TM. Recurrence developed in 5 patients (8.6%) in IGM and 1 patient (10%) in TM. CONCLUSION: This study shows different characteristics between IGM and TM. The IGM patients were younger and had more mastalgia symptoms than the TM patients. Axillary lymphadenopathy was seen more often in TM patients. Half of the TM patients had pulmonary tuberculosis or tuberculosis lymphadenitis. Surgical wide excision might be both therapeutic and useful for providing an exact diagnosis.

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.

PURPOSE: The prediction of breast cancer recurrence is a crucial factor for successful treatment and follow-up planning. The principal objective of this study was to construct a novel prognostic model based on support vector machine (SVM) for the prediction of breast cancer recurrence within 5 years after breast cancer surgery in the Korean population, and to compare the predictive performance of the model with the previously established models. METHODS: Data on 679 patients, who underwent breast cancer surgery between 1994 and 2002, were collected retrospectively from a Korean tertiary teaching hospital. The following variables were selected as independent variables for the prognostic model, by using the established medical knowledge and univariate analysis: histological grade, tumor size, number of metastatic lymph node, estrogen receptor, lymphovascular invasion, local invasion of tumor, and number of tumors. Three prediction algorithms, with each using SVM, artificial neural network and Cox-proportional hazard regression model, were constructed and compared with one another. The resultant and most effective model based on SVM was compared with previously established prognostic models, which included Adjuvant! Online, Nottingham prognostic index (NPI), and St. Gallen guidelines. RESULTS: The SVM-based prediction model, named 'breast cancer recurrence prediction based on SVM (BCRSVM),' proposed herein outperformed other prognostic models (area under the curve=0.85, 0.71, 0.70, respectively for the BCRSVM, Adjuvant! Online, and NPI). The BCRSVM evidenced substantially high sensitivity (0.89), specificity (0.73), positive predictive values (0.75), and negative predictive values (0.89). CONCLUSION: As the selected prognostic factors can be easily obtained in clinical practice, the proposed model might prove useful in the prediction of breast cancer recurrence. The prediction model is freely available in the website (http://ami.ajou.ac.kr/bcr/).

PURPOSE: A 70-gene prognostic signature has prognostic value in patients with node-negative breast cancer in Europe. This diagnostic test known as "MammaPrint(TM) (70-gene prognostic signature)" was recently validated and implementation was feasible. Therefore, we assessed the 70-gene prognostic signature in Korean patients with breast cancer. We compared the risk predicted by the 70-gene prognostic signature with commonly used clinicopathological guidelines among Korean patients with breast cancer. We also analyzed the 70-gene prognostic signature and clinicopathological feature of the patients in comparison with a previous validation study. METHODS: Forty-eight eligible patients with breast cancer (clinical T1-2N0M0) were selected from four hospitals in Korea. Fresh tumor samples were analyzed with a customized microarray for the 70-gene prognostic signature. Concordance between the risk predicted by the 70-gene prognostic signature and risk predicted by commonly used clinicopathological guidelines (St. Gallen guidelines, National Institutes of Health [NIH] guideline, and Adjuvant! Online) was evaluated. RESULTS: Prognosis signatures were assessed in 36 patients. No significant differences were observed in the clinicopathological features of patients compared with previous studies. The 70-gene prognosis signature identified five (13.9%) patients with a low-risk prognosis signature and 31 (86.1%) patients with a high-risk prognosis signature. Clinical risk was concordant with the prognosis signature for 29 patients (80.6%) according to the St. Gallen guidelines; 30 patients (83.4%) according to the NIH guidelines; and 23 patients (63.8%) according to the Adjuvant! Online. Our results were different from previous validation studies in Europe with about a 40% low-risk prognosis and about a 60% high-risk prognosis. The high incidence in the high-risk group was consistent with data in Japan. CONCLUSION: The results of 70-gene prognostic signature of Korean patients with breast cancer were somewhat different from those identified in Europe. This difference should be studied as whether there is a gene disparity between Asians and Europeans. Further large-scale studies with a follow-up evaluation are required to assess whether the use of the 70-gene prognostic signature can predict the prognosis of Korean patients with breast cancer.

PURPOSE: Since 1996, the Korean Breast Cancer Society has collected nation-wide breast cancer data and analyzed the data using their online registration program biannually. The purpose of this study was to evaluate the characteristics of Korean breast cancer from 2008 and examine chronological based patterns. METHODS: Data were collected from 38 medical schools (67 hospitals), 20 general hospitals, and 10 private clinics. The data on the total number, gender, and age distribution were collected through a questionnaire as well as other detailed data analyzed via the online registration program. RESULTS: In 2008, there were 13,908 patients who were newly diagnosed with breast cancer. The crude incidence rate of female breast cancer was 57.3 among 100,000 and the median age was 49 years. The age distribution had not changed since the initial survey; however the proportion of postmenopausal patients had increased and median age was older than the past. In staging distribution, the proportion of early breast cancer (stage 0, I) was 47.2% with, breast-conserving surgery performed in 58% and mastectomy in 39.5%. CONCLUSION: Compared to past data, the incidence of breast cancer in Korea continues to rise. Furthermore, the proportion of those detected by screening and breast conservation surgery has increased remarkably. To understand the patterns of Korean breast cancer, the nation-wide data should continuously investigated.

PURPOSE: Trauma is one of the leading causes of death, especially among young people. Life-threatening conditions are very common in multiple-traumatized patients due to concurrent multi-organ injuries. Treating such severely injured patients is time critical. However, in Korea, the transfer of severely injured patients is not uncommon due to the lack of a mature trauma care system. In developed countries, the preventable trauma death rate is very low, but the rate is still very high in Korea. This study's objective was to demonstrate the current serious state in which severely injured patients have to be transferred from a Regional Emergency Medical Center even though it actually serves as a trauma center. METHODS: Ajou University Medical Center is a tertiary hospital that serves as a trauma center in Gyeonggi-do. The medical records at Ajou University Medical Center for a 1-year period from January 1, 2008, to December 31, 2008, were retrospectively reviewed. A severely injured patient was defined as a patient who showed more than 15 point on the ISS (injury severity score) scale. We investigated the clinical characteristics of such patients and the causes of transfer. RESULTS: Out of 81,718 patients who visited the Regional Emergency Medical Center, 19,731 (24.1%) were injured patients. Among them, 108 severely-injured patients were transferred from one Regional Emergency Medical Center to other hospitals. The male-to-female ratio was about 3.5:1, and the mean ISS was 23.08. The most common mechanism of injury was traffic accidents (41.7%). A major cause of transfer was the shortage of intensive care units (44.4%); another was for emergent operation (27.8%). Most of the hospitals that received the severely-injured patients were secondary hospitals (86.1%). CONCLUSION: Although the Regional Emergency Medical Center played a role as a trauma center, actually, severely-injured patients had to be transferred to other hospitals for several reasons. Most reasons were related with the deficiencies in the trauma care system. If a mature trauma care system is well-organized, the numbers of transfer of severely injured patients will be reduced significantly.

The aim of this study is to investigate the use of absorbable mesh in breast surgery in Korea. We conducted a survey from members of Korea Breast Cancer Society by phone, E-mail, and notice on the website from 6th to 20th April 2009. A total of 54 breast surgeons had responded to the survey. Of these, 40 surgeons (74.1%) had used absorbable mesh during breast surgery, with Vicryl mesh(R) being the choice of every surgeon and Interceed(R) having been used by 36 (90%) of the surgeons. In responding to the indications for mesh use, 26 surgeons (65%) indicated that mesh use was effective when a deformity was expected regardless of T stage. Contraindications for mesh use principally included existing patients' comorbidity such as a wound healing problem, diabetes mellitus and immunocompromised condition. Thirty one surgeons (77.5%) had experienced an infection in the mesh insertion site. However, on a case basis, only 39 of 843 cases (4.6%) had resulted in an infection. In the follow up after mesh use, 33 of the 37 responding surgeons (89.2%) used breast ultrasonography. Nineteen of the 38 respondents (50%) replied that the mesh was absorbed in 6 months and it did not confuse diagnostic imaging. The cited merits of mesh included maintenance of breast shape following surgery (n=38/49, 77.6%) and ease of surgical use (n=35/49, 71.4%). However, the high price of mesh was cited as a disadvantage by 33 of the 48 respondents (68.8%). In summary, survey results mentioned above show that surgical mesh use in breast surgery is increasing by times and the procedures greatly varies by surgeons. Thereby, we suggest that a guideline for mesh use should be made in the near future.
