ABSTRACT

Purpose@#Physicians' awareness of their cancer patients' unmet needs is an essential element for providing effective treatment. This study investigated the accuracy of physicians' awareness of breast cancer survivors' unmet needs in Korea. @*Methods@#A cross-sectional interview survey was performed among 106 physicians and 320 Korean breast cancer survivors. The Comprehensive Needs Assessment Tool was administered to physicians and cancer survivors after obtaining their written informed consent to participate. Data were analyzed using t-test, analysis of variance, and multiple regression analysis. @*Results@#The level of unmet needs was highest in the hospital service domain (mean ± standard deviation: 2.19 ± 0.82), and the top-ranked unmet need item was “wished my doctor to be easy, specific, and honest in his/her explanation” (2.44 ± 0.93). Higher unmet needs were correlated with the presence of a genetic counseling clinic. They were not associated with age, sex, marital status, religion, department, working period, type of institution, number of staff, and number of operations. In multiple regression analysis, the presence of a genetic counseling clinic was associated with a higher level of recognition for psychological problems, social support, hospital service, and information and education needs. Physicians overestimated breast cancer survivors' unmet needs in all domains, compared to their selfreported unmet needs. The discordance in the perceived unmet needs was highest in the ‘family/personal relationship problems’ domain. @*Conclusions@#Physicians who treat Korean breast cancer survivors rated the level of unmet needs of breast cancer survivors as highest in the hospital service domain. The presence of a genetic counseling clinic in physicians' institutions was associated with a higher perception of survivors' unmet needs. Physicians overestimated the level of unmet needs in Korean breast cancer survivors. Efforts to reduce these discordances are needed to implement optimal survivorship care.

ABSTRACT

Purpose@#As the survival rates of cancer patients have been increasing due to early diagnosis and technological advances in treatment, their caregiver burden has also emerged as an important issue. In view of this situation, this study aims to investigate the unmet needs and quality of life of caregivers of Korean breast cancer survivors. @*Methods@#A multicenter cross-sectional interview survey was performed among 160 caregivers of Korean breast cancer survivors. Caregivers who gave written informed consent to participate completed the Comprehensive Needs Assessment Tool for Cancer Caregivers and EuroQol-5 Dimensions. @*Results@#The mean age of the caregivers was 46.4 years, 44.4% (71 of 160) were spouses of patients, and 52.5% (84 of 160) were personally taking care of cancer survivors. Unmet needs were highest in the ‘healthcare staff’ domain and the item with the highest level of unmet needs was ‘needed information about the current status of the patient’s illness and its future courses.’ Poorer quality of life was closely related to higher levels of unmet needs. In multiple regression analysis, older age, employment, the presence of religion, and higher levels of stress and despair in daily life were associated with higher levels of unmet needs. @*Conclusion@#The most prevalent unmet need in Korean breast cancer caregivers was found in the ‘healthcare staff’ domain, and their quality of life was closely related to unmet needs. Therefore, healthcare staff is required to make efforts to accurately identify breast cancer caregivers vulnerable in terms of unmet needs and address their unmet needs.

ABSTRACT

Purpose@#This study aimed to investigate and analyze the current fertility-related practices for breast cancer patients; the results are intended to help improve the quality of life of young patients and survivors. @*Methods@#This study collected voluntary responses to a questionnaire that was used to survey Korean breast cancer specialists. The questionnaire consisted of five categories: knowledge, practice behaviors regarding fertility preservation, barriers to discussing fertility preservation, attitude toward fertility issues, and demographics and medical background. @*Results@#A total of 120 copies of the questionnaire were distributed; the response rate was 89%. The section of the questionnaire regarding knowledge indicated that most respondents had adequate fertility preservation knowledge for cancer patients. However, 13.1% of the respondents indicated that they thought pregnancy increased the cancer recurrence risk. Respondents’ knowledge and attitudes about fertility preservation were not correlated with actual practice. The absence of patient’s expressions (24.30%), high recurrence risk (27.10%), insufficient time in the clinic (21.50%), and hospital conditions such as no reproductive specialists or infertility clinic (16.82%), were considered major barriers to discussing fertility issues. @*Conclusion@#Although more than 50% of the respondents thought that cancer treatment is more important than fertility preservation and it is complex and difficult, the Korean breast surgical oncologists were generally encouraging when discussing fertility issues with young breast cancer patients. Hence, breast clinicians should share with young patients the updated evidence regarding the feasibility and safety of pregnancy after cancer treatment and the available options so that the best decisions can be made.

ABSTRACT

PURPOSE: Cardiotoxicity is a serious late complication of breast cancer treatment. Individual treatment risk of specific drugs has been investigated. However, studies on the evaluation of the composite risk of chemotherapeutic agents are limited.METHODS: We retrospectively analyzed the medical records of breast cancer patients who received adjuvant treatment and had available serial echocardiography results. Patients were assigned to subgroups based on chemotherapy containing anthracyclines (A), anthracyclines and taxanes (A+T), and radiotherapy (RT). The development of cardiac disease and serial ejection fraction (EF) were reviewed. EF decline up to 10% from baseline was considered grade 1 cardiotoxicity and EF decline >20% or absolute value < 50% was considered grade 2 cardiotoxicity. The most recent medical records and echocardiography results over 1 year of chemotherapy completion were also reviewed. Late cardiotoxicity was defined as a lack of recovery of EF decline or aggravated EF decline from baseline.RESULTS: In total, 123 patients were evaluated. A small reduction in EF was observed after chemotherapy in both chemotherapy groups. There were no significant differences between groups A and A+T in EF decline following chemotherapy. We could not find any differences in composite risk between the chemotherapy groups and the RT group during follow-up. Late cardiotoxicity was seen in 15.45% of patients. During follow-up, three patients were diagnosed with dilated cardiomyopathy.CONCLUSION: There was no significant composite risk elevation following adjuvant treatment of breast cancer. However, late cardiotoxicity was considerable and further research in this direction is necessary.

ABSTRACT

PURPOSE: Primary prophylaxis with granulocyte colony-stimulating factor can effectively prevent febrile neutropenia (FN) during breast cancer treatment. The aims of this study were to evaluate the incidence of FN and the ANC profile in patients undergoing chemotherapy and pegfilgrastim primary prophylaxis. METHODS: Patients receiving 6 cycles of adjuvant docetaxel, doxorubicin, and cyclophosphamide (TAC) chemotherapy were included in this study. Pegfilgrastim was administered with analgesics 24 hours after treatment. Laboratory tests were performed on day 0 (before chemotherapy) and ANC was measured daily starting day 5 until it were restored to 1,000/mm3. Bone pain was checked via the numeral rating scale (NRS). RESULTS: A total of 61 patients and 366 cycles were evaluated. Mean age was 49.2 ± 7.1 years. FN was seen in 5 patients (16.4%) and 12 cycles (3.3%) with pegfilgrastim. Grades 3 and 4 neutropenia was seen in 91.5% of cycles with FN. The ANC nadir was most commonly seen at day 7 and the mean ANC nadir depth was 265.7/m3. Age was negatively correlated with nadir depth (r = −0.137, P = 0.009). Severe pain higher than NRS 7 occurred in less than 20% of patients after the administration of pegfilgrastim. CONCLUSION: Incidence of FN was low during the chemotherapy by primary prophylaxis with pegfilgrastim. The ANC nadir was seen on day 7 after chemotherapy. Bone pain with pegfilgrastim was well tolerated during TAC chemotherapy.

ABSTRACT

OBJECTIVES: The purpose of this study was to examine the associations of childbirth, breastfeeding, and their interaction with breast cancer (BC) risk reduction, and to evaluate the heterogeneity in the BC risk reduction effects of these factors by menopause, hormone receptor (HR) status, and pathological subtype. METHODS: BC patients aged 40+ from the Korean Breast Cancer Registry in 2004-2012 and controls from the Health Examinee cohort participants were included in this study after 1:1 matching (12 889 pairs) by age and enrollment year. BC risk according to childbirth, breastfeeding, and their interaction was calculated in logistic regression models using odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: BC risk decreased with childbirth (3+ childbirths relative to 1 childbirth: OR, 0.66; 95% CI, 0.56 to 0.78 and OR, 0.80; 95% CI, 0.68 to 0.95 in postmenopausal and premenopausal women, respectively); and the degree of risk reduction by the number of children was heterogeneous according to menopausal status (p-heterogeneity=0.04), HR status (p-heterogeneity < 0.001), and pathological subtype (p-heterogeneity < 0.001); whereas breastfeeding for 1-12 months showed a heterogeneous association with BC risk according to menopausal status, with risk reduction only in premenopausal women (p-heterogeneity < 0.05). The combination of 2 more childbirths and breastfeeding for ≥13 months had a much stronger BC risk reduction of 49% (OR, 0.51; 95% CI, 0.45 to 0.58). CONCLUSIONS: This study suggests that the combination of longer breastfeeding and more childbirths reduces BC risk more strongly, and that women who experience both 2 or more childbirths and breastfeed for ≥13 months can reduce their BC risk by about 50%.

ABSTRACT

Lack of awareness, the stigma of carrying a genetic mutation, and economic factors are barriers to acceptance of BRCA genetic testing or appropriate risk management. We aimed to investigate the influence of Angelina Jolie's announcement of her medical experience and also health insurance reimbursement for BRCA gene testing on practice patterns for hereditary breast and ovarian cancer (HBOC). A survey regarding changes in practice patterns for HBOC before and after the announcement was conducted online. The rate of BRCA gene testing was obtained from the National Health Insurance Review and Assessment Service database. From May to August 2016, 70 physicians responded to the survey. Genetic testing recommendations and prophylactic management were increased after the announcement. Risk-reducing salpingo-oophorectomy and contralateral prophylactic mastectomy was significantly increased in BRCA carriers with breast cancer. The BRCA testing rate increased annually. Health insurance and a celebrity announcement were associated with increased genetic testing.

ABSTRACT

PURPOSE: Breast cancer survivors have slightly increased the risk of second primary cancers. Breast, colon, uterine, and ovarian cancers are common secondary cancers in breast cancer survivors. In this study, we assessed the development of second primary cancers of breast cancer survivors in Korea. METHODS: Medical records of patients with breast cancer in 3 tertiary medical institutions were reviewed retrospectively. We evaluated secondary malignancy diagnosed at least 2 months after the breast cancer diagnosis. Based on the International Classification of Disease-9 codes of malignancies, secondary primary breast cancer records were evaluated with person-year adjustment. The standardized incidence ratio (SIR) was assessed using national cancer incidence. RESULTS: A total of 3,444 treatment records were included from 3 medical centers. The cumulative incidence of overall second primary cancers was 2.8% (n = 93). The SIR was significantly higher in all sites (1.56; 95% confidence interval [CI], 1.26–1.91), endometrial cancer (5.65; 95% CI, 2.06–12.31), biliary tract cancer (3.96; 95% CI, 1.19–8.60), and thyroid cancer (2.29; 95% CI, 1.67–3.08). CONCLUSION: The incidence of cancer was higher in breast cancer survivors compared to general population. Surveillance of secondary cancer in this group should be recommended individually considering the benefit related to the prognosis of primary breast cancer.

ABSTRACT

PURPOSE: Germline mutations in the BRCA1 and BRCA2 genes confer increased risks for breast cancers. However, the clinical presentation of breast cancer among women who are carriers of the BRCA1 or BRCA2 (BRCA1/2 carriers) mutations is heterogenous. We aimed to identify the effects of the reproductive histories of women with the BRCA1/2 mutations on the clinical presentation of breast cancer. METHODS: We retrospectively analyzed clinical data on women with proven BRCA1 and BRCA2 mutations who were recruited to the Korean Hereditary Breast Cancer study, from 2007 to 2014. RESULTS: Among the 736 women who were BRCA1/2 mutation carriers, a total of 483 women had breast cancers. Breast cancer diagnosis occurred at significantly younger ages in women who experienced menarche at ≤14 years of age, compared to those who experienced menarche at >14 years of age (37.38±7.60 and 43.30±10.11, respectively, p<0.001). Additionally, the number of full-term pregnancies was significantly associated with the age of diagnosis, especially in women with the BRCA2 mutation. The prevalence of advanced stages (stage II or III vs. stage I) of disease in parous women was higher than in nulliparous women (68.5% vs. 55.2%, p=0.043). This association was more pronounced in women with the BRCA2 mutation (hazard ratio, 2.67; p=0.014). CONCLUSION: Our results suggest that reproductive factors, such as the age of onset of menarche and the presence of parity, are associated with the clinical presentation patterns of breast cancer in BRCA1/2 mutation carriers.

ABSTRACT

PURPOSE: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. METHODS: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. RESULTS: The mean duration of the follow-up period was 91.6 months (range, 33.3-171.0 months), and mean age of the patients was 51 years old (range, 33-72 years). The mean tumor size was 2.1 cm (range, 0.9-5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain-satisfaction with breasts (R2 = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R2 = 0.085, P = 0.023), sexual well-being (R2 = 0.082, P = 0.029), and satisfaction with information (R2 = 0.064, P = 0.049). CONCLUSION: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.

ABSTRACT

PURPOSE: Follow-up after primary treatment for breast cancer is an important component of survivor care and various international guidelines exist for the surveillance. However, little is known about current actual practice patterns of physicians whether they adhere to or deviate from recommended guidelines. The aim of this study was to determine how physicians follow-up their patients after primary treatment for breast cancer in Korea. METHODS: A questionnaire survey with 34 questions in 4 categories was e-mailed to the members of Korean Breast Cancer Society from November to December 2013. Respondents were asked how they use follow-up modalities after primary treatment of breast cancer and we compared the survey results with present guidelines. RESULTS: Of the 129 respondents, 123 (95.3%) were breast surgeons. The most important consideration in follow-up was tumor stage. History taking, physical examinations, and mammography were conducted in similar frequency recommended by other guidelines while breast ultrasonography was performed more often. The advanced imaging studies such as CT, MRI, and bone scan, which had been recommended to be conducted only if necessary, were also examined more frequently. Regular screenings for secondary malignancy were performed in 38 respondents (29.5%). Five years later after primary treatment, almost the whole respondents (94.6%) themselves monitored their patients. CONCLUSION: A majority of respondents have been performed more intensive follow-up modalities in comparison with present guidelines and less frequently screenings for secondary malignancy. For optimal follow-up of breast cancer survivors, tailored delivery system should be considered.

ABSTRACT

PURPOSE: Mutations in BRCA genes are the main cause of hereditary breast cancer in Korea. The aim of this study was to investigate the characteristics of breast cancers involving BRCA1 (BRCA1 group) and BRCA2 (BRCA2 group) mutations. METHODS: We retrospectively reviewed the medical records of patients with BRCA1 (BRCA1 group) or BRCA2 (BRCA2 group) mutation positive breast cancer from multiple centers and compared the data to that of the Korean Breast Cancer Society registry (registry group). RESULTS: The patients of the BRCA1 group were diagnosed at a younger age (median age, 37 years) and had tumors of higher histological (61.3% with histological grade 3) and nuclear (37.5% with nuclear grade 3) grade than those of the registry group. In addition, the frequency of ductal carcinoma in situ in the BRCA1 group was lower (3.7%) than in the registry group, and the BRCA1 group were more likely to be triple-negative breast cancer (61.3%). Patients in the BRCA2 group were also younger at diagnosis (mean age, 41 years) and were more likely to have involvement of the axillary node than the registry group (45.5% vs. 33.5%, p=0.002). The BRCA1 and BRCA2 groups did not show a correlation between tumor size and axillary node involvement. CONCLUSION: We report the characteristics of BRCA mutation positive breast cancer patients in the Korean population through multicenter data and nation-wide breast cancer registry study. However, BRCA-mutated breast cancers appear highly complex, and further research on their molecular basis is needed in Korea.

ABSTRACT

Despite the fact that more breast cancer survivors are currently enjoying longer lifespans, there remains limited knowledge about the factors and issues that are of greatest significance for these survivors, particularly from their perspectives. This review was based on the concept that the topics addressed should focus on the perspectives of current survivors and should be extended to future modalities, which physicians will be able to use to gain a better understanding of the hidden needs of these patients. We intended to choose and review dimensions other than the pathology and the disease process that could have been overlooked during treatment. The eight topics upon which we focused included: delay of treatment and survival outcome; sexual well-being; concerns about childbearing; tailored follow-up; presence of a family history of breast cancer; diet and physical activity for survivors and their families; qualitative approach toward understanding of breast cancer survivorship, and; mobile health care for breast cancer survivors. Through this review, we aimed to examine the present clinical basis of the central issues noted from the survivors' perspectives and suggest a direction for future survivorship-related research.

ABSTRACT

PURPOSE: Systematic educational programs and genetic counseling certification courses for hereditary breast/ovarian cancer (HBOC) have not yet been introduced in Korea. We provided and evaluated the effects of genetic counseling education on Korean healthcare providers' knowledge, awareness, and counseling skills for patients at high risk of HBOC. METHODS: A 3-day educational program was conducted for healthcare providers who were interested in genetic counseling for patients at high risk of HBOC. Participants who completed a knowledge test and satisfaction questionnaire were included in the present sample. Pre-post comparisons were conducted to determine the effects of the intervention. RESULTS: Significant differences between preprogram and postprogram knowledge scores were observed (p=0.002). Awareness (p<0.001) and confidence (p<0.001) regarding genetic counseling significantly increased after the training. Doctors and participants with fewer years of work experience performed well on the knowledge test. Previous educational experience was correlated with increased confidence in knowledge and counseling skills. CONCLUSION: Genetic counseling education regarding HBOC improved knowledge and awareness of HBOC and enhanced confidence in the counseling process. The effects varied according to occupation and participants' previous education. The implementation of systematic educational programs that consider participant characteristics may improve the effects of such interventions.

ABSTRACT

PURPOSE: Few studies have reported ovarian cancer risks in Korean patients with the BRCA1/2 mutation. We investigated the prevalence of ovarian cancer in Korean women at high risk for hereditary breast-ovarian cancer (HBOC) syndrome and reviewed the clinicopathological factors of ovarian cancer. METHODS: Female subjects who were enrolled in the Korean Hereditary Breast Cancer study were included. The questionnaire included a personal and family history of cancer. The BRCA1/2 mutation and CA-125 level were tested at the time of enrollment. A transvaginal ultrasonogram (TVUS) was recommended for subjects with an elevated CA-125 level. RESULTS: A total of 1,689 patients were included. No ovarian cancer was newly diagnosed by CA-125 level or TVUS during the enrollment. The prevalence of ovarian cancer was 1.71% in BRCA1/2 mutation carriers and 0.39% in non-carriers. Among 11 patients with ovarian cancer, five had the BRCA1 mutation and one had the BRCA2 mutation. The most common histopathological type was serous cystadenocarcinoma. No difference in clinicopathological findings between BRCA1/2 mutation carriers and non-carriers was observed. CONCLUSION: The prevalence of ovarian cancer was 58-fold elevated in women at high-risk for HBOC syndrome and 146-fold elevated in the BRCA1 subgroup, compared with the Korean general population. Further investigation with a long-term follow-up is required to evaluate BRCA1/2 gene penetrance.

ABSTRACT

PURPOSE: Recent randomized phase III trial by the Breast Cancer International Research Group (BCIRG 001) showed that docetaxel plus doxorubicin and cyclophosphamide (TAC) is superior to fluorouracil plus doxorubicin and cyclophosphamide (FAC) as adjuvant chemotherapy for node-positive operable breast cancer. Unfortunately, TAC was clearly more toxic than FAC not only with respect to neutropenic fever events, but also with respect to many extrahematological side effects. The aim of this study was to evaluate the toxicity and tolerability of Korean patients with breast cancer treated with TAC. METHODS: This study was conducted on 80 patients with breast cancer who underwent primary surgery at the Department of Surgery in Soonchunhyang University (4 affiliated hospitals) from October 2005 to October 2008. The patients received 480 courses consisting of TAC (75/50/500 mg/m2, every 3 weeks for 6 cycles) without prophylactic granulocyte colony-stimulating factor (G-CSF). Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria version 3.0. RESULTS: The main toxicities were hematologic (neutropenia grade 3/4 in 98.8% of patients and 92.3% of cycles; febrile neutropenia in 42.5% of patients and 16.0% of cycles). No cases of septic death occurred. The peak time of occurrence for febrile neutropenia was 7-10 days after receiving chemotherapy (mean duration, 2.05 days). Severe nonhematologic adverse events were as follows: myalgia (30.0%), neurotoxicity (17.5%), fatigue (16.3%), stomatitis (12.5%), and nausea (11.3%). CONCLUSION: An adjuvant TAC regimen without prophylactic G-CSF was tolerable in Korean patients with breast cancer. Although most of the patients developed neutropenia, the nonhematologic toxicities (cardiac toxicity) were tolerable. Further studies on prophylactic G-CSF use to assess the contribution to reduced hematologic toxicities are required in Korean patients with breast cancer.
