The purpose of this study was to identify the relationship between self reported climacteric symptoms, knowledge of menopause, menopausal management, in middle-aged women. The subjects of this study were 209 women from 40 to 64 years of age. The data was analyzed using SPSS program for t-test, ANOVA and Pearson's correlation coefficients. The results of the study were as follows : 1. The characteristic variables significantly related to self reported climacteric symptoms were education(F=6.371, p<0.001), income (F=4.481, p<0.05), mensturation state(t= -2.004, p<0.05), mensturation cycle(t=-2.039, p<0.05), hormone therapy(t=2.107, p<0.05), health condition(F=21.111, p<0.001).2. The characteristic variables significantly related to knowledge of menopause were education(F=6.580, p<0.001), health condition (F=3.487, p<0.05).3. The characteristic variable significantly related to menopausal management was income(F=3.080, p<0.05). 4. The relationship between self reported climacteric symptoms and menopausal management was statistically significant with a negative correlation(r=-0.323, p<0.05).In conclusion, climacteric symptoms - based complaints by middle-aged women was negatively correlated to menopausal management. Therefore, health promotions designed to increase climacteric women's health should be a planned program based on results of the study.

PURPOSE: This study was conducted to investigate the current role of medical oncologists in cancer care with a focus on increasing the recognition of medical oncology as an independent specialty. MATERIALS AND METHODS: Questionnaires modified from the Medical Oncology Status in Europe Survey dealing with oncology structure, resources, research, and patterns of care given by medical oncologists were selected. Several modifications were made to the questionnaire after feedback from the insurance and policy committee of the Korean Association for Clinical Oncology (KACO). The online survey was then sent to KACO members. RESULTS: A total of 214 medical oncologists (45.8% of the total inquiries), including 71 directors of medical oncology institutions, took the survey. Most institutions had various resources, including a medical oncology department (94.1%) and a department of radiation oncology (82.4%). There was an average of four medical oncologists at each institution. Medical oncologists were involved in various treatments from diagnosis to end-of-life care. They were also chemotherapy providers from a wide range of institutions that treated many types of solid cancers. In addition, 86.2% of the institutions conducted research. CONCLUSION: This is the first national survey in Korea to show that medical oncologists are involved in a wide range of cancer treatments and care. This survey emphasizes the contributions and proper roles of medical oncologists in the evolving health care environment in Korea.

BACKGROUND/AIMS: To evaluate and select microRNAs relevant to acute myeloid leukemia (AML) pathogenesis, we analyzed differential microRNA expression by quantitative small RNA next-generation sequencing using duplicate marrow samples from individual AML patients. METHODS: For this study, we obtained paired marrow samples at two different time points (initial diagnosis and first complete remission status) in patients with AML. Bone marrow microRNAs were profiled by next-generation small RNA sequencing. Quantification of microRNA expression was performed by counting aligned reads to microRNA genes. RESULTS: Among 38 samples (32 paired samples from 16 AML patients and 6 normal marrow controls), 27 were eligible for sequencing. Small RNA sequencing showed that 12 microRNAs were selectively expressed at higher levels in AML patients than in normal controls. Among these 12 microRNAs, mir-181, mir-221, and mir-3154 were more highly expressed at initial AML diagnosis as compared to first complete remission. Significant correlations were found between higher expression levels of mir-221, mir-146, and mir-155 and higher marrow blast counts. CONCLUSIONS: Our results demonstrate that mir-221 and mir-181 are selectively enriched in AML marrow and reflect disease activity. mir-3154 is a novel microRNA that is relevant to AML but needs further validation.

BACKGROUND/AIMS: Managing breakthrough pain (BTP) is important for many cancer patients because of the rapid onset and unpredictable nature of the pain episodes. Fentanyl buccal tablets (FBTs) are a rapid-onset opioid indicated for BTP management. However, FBT titration is needed to optimize BTP management. In this study, we aimed to evaluate the safety and efficacy of initiating 200 μg FBTs in Korean cancer patients. METHODS: A retrospective analysis of medical records was performed on all advanced cancer patients treated with FBTs for BTP between October 2014 and July 2015. Patients who received initial doses of 200 μg FBTs for at least 3 days and cases in which FBT was available at doses of 200, 400, and 800 μg were included. RESULTS: A total of 56 patients with a median age of 62 years (range, 32 to 80) were analyzed, 61% of whom were male. The median and mean values of morphine equivalent daily doses were 60 mg/day (range, 15 to 540) and 114.8 ± 124.8 mg/day, respectively. The most frequent effective doses of FBT were 200 μg (41 patients, 74%) and 400 μg (12 patients, 21%). Three patients (5%) could not tolerate 200 μg of FBT and discontinued treatment. Nausea, vomiting, somnolence, and dizziness were the most frequent treatment-related adverse events (AEs), and all AEs were grade 1 (mild) or 2 (moderate). CONCLUSIONS: FBT at the initial 200 μg dosage was well-tolerated and effective as a BTP management strategy in Korean cancer patients. Further prospective studies are needed to determine appropriate initiating doses of FBT in Korean patients with opioid tolerance.

Cancer Research and Treatment 2020;52(4):1002-1009
Purpose:
This study aimed to investigate the prevalence and risk factors of burnout and occupational stress among medical oncologists in Korea.
Methods:
A survey was conducted of medical oncologists who were members of Korean Society for Medical Oncology (KSMO) using the Korean Occupational Stress Scale, the validated Maslach Burnout Inventory (MBI) and supplemental questions about work and lifestyle factors.
Results:
Among 220 active KSMO members, 111 responses were collected. The median age was 42 years (range, 32 to 63 years). Two-thirds of responders worked 6 days per week and half of them worked a total of 60-80 hours per week. Each medical oncologist treated a median of 90-120 patients per week in outpatient clinics and 20-30 patients per week in patient practices. MBI subscales indicated a high level of emotional exhaustion in 74%, a high level of depersonalization in 86%, and a low level of personal accomplishment in 65%: 68% had professional burnout according to high emotional exhaustion and high depersonalization scores. The risk of burnout was higher for medical oncologists aged from 30-39 than 40-49 years, and unmarried than married. Considering personal accomplishment, females had a higher risk of burnout. The median score of occupational stress was 63 (range, 43 to 88). Having night-duty call was the strongest risk factor on more stress. A higher stress score was associated with a higher prevalence of burnout.
Conclusion
Burnout and occupational stress are quite common amongst Korean medical oncologists. Achieving a healthy work-life balance, ensuring balanced workload distribution, and engaging in proper stress relief solutions are necessary.

Erdheim-Chester disease is a rare non-Langerhans-cell histiocytosis involving bones and multiple organs. Its clinical course can vary, from an asymptomatic state to a fatal disease, with renal involvement being a common cause of death. A 41-year-old man presented with a 10-month history of bilateral lower limb pain. Left perirenal soft-tissue infiltration had been found incidentally two years earlier. No progression of the lesion or deterioration of renal function was observed for a period of two years. At admission, plain radiography and magnetic resonance imaging of the patient's lower limbs showed patchy osteosclerosis. Biopsy of the tibia revealed histiocytic infiltration, which was found to be positive for CD68 and negative for CD1a. This report describes an unusual case of Erdheim-Chester disease involving a stationary course of disease with no specific treatment for a long period of time.

PURPOSE: This study was conducted to explore the process and operation of a cancer multidisciplinary team (MDT) after the reimbursement decision in Korea, and to identify ways to overcome the major barriers to effective and sustainable MDTs. MATERIALS AND METHODS: Approximately 1,000 cancer specialists, including medical oncologists, surgical oncologists, radiation oncologists, pathologists, and radiologists in general hospitals in Koreawere invited to complete the survey. The questionnaire covered the following topics: organizational structure of MDTs, candidates for consulting, the clinical decision-making initiative, and responsibility for dealing with legal disputes. RESULTS: We collected a total of 179 responses (18%) from physicians at institutions where an MDT approach was active. A surgical oncologist (91%), internist (90%),radiologist (89%),radiation oncologist (86%), pathologist (71%), and trainees (20%) regularly participated in MDT operations. Approximately 55% of respondents stated that MDTs met regularly. In cases of a split opinion, the physician in charge (69%) or chairperson (17%) made the final decision, and most (86%) stated they followed the final decision. About 15% and 32% of respondents were “very satisfied” and “satisfied,” respectively, with the current MDT's operations. Among 38 institutional representatives, 34% responded that the MDT operation became more active and 18% stated an MDT was newly implemented after the reimbursement decision. CONCLUSION: The reimbursement decision invigorated MDT operations in almost half of eligible hospitals. Dissatisfaction regarding current MDTs was over 50%, and the high discordance rates regarding risk sharing suggest that it is necessary to revise the current system of MDTs.
