ABSTRACT

The prognosis of patients with advanced hepatocellular carcinoma (HCC) with tumor thrombus extending to the inferior vena cava (IVC) is extremely poor. Herein, we present a rare case of advanced HCC that was treated with sorafenib and radiotherapy, leading to complete remission. This patient had a 9 cm infiltrative HCC occupying almost the entire left lobe with a tumor thrombus extending through the hepatic vein, IVC, and left portal vein. The patient received 400 mg sorafenib twice daily. One year after the start of sorafenib, intensity-modulated radiation therapy for viable HCC and tumor thrombus was performed with a dose of 5,500 cGy. Twenty-seven months after the starting date of sorafenib, there was no intratumoral arterial enhancement, which suggested a complete response according to the modified RECIST criteria. This case suggests that the combination of sorafenib and radiotherapy might provide clinical benefits in patients with advanced HCC with IVC tumor thrombus.

ABSTRACT

Background@#For OSCE (Objective Structured Clinical Examination) scoring, medical schools must bring together many clinical experts at the same place, which is very risky in the context of the coronavirus pandemic. However, if the FLEX model with the properties of self-directed learning and offline feedback is applied to OSCE, it is possible to provide a safe and effective evaluation environment for both universities and students through experts’ evaluation of selfvideo clips of medical students. The present study investigated validity of the FLEX model to evaluate OSCE in a small group of medical students. @*Methods@#Sixteen 3 rd grade medical students who failed on OSCE were required to take a make-up examination by videotaping the failed items and submitting them online. The scores between original examination and make-up examination were compared using Paired Wilcoxon Signed Rank Test, and a post-hoc questionnaire was conducted. @*Results@#The score for make-up examination was significantly higher than those for original examination. The significance was maintained even when the score was compared by individual domains of skills and proficiency. In terms of preference, students were largely in favor of self-videotaped examination primarily due to the availability of self-practice. @*Conclusion@#The FLEX model can be effectively applied to medical education, especially for evaluation of OSCE.

ABSTRACT

Background@#In patients with early-stage breast cancer, the treatment results of hypofractionated radiation therapy (RT) and conventional RT are evaluated in efficacy and cost. @*Methods@#We retrospectively evaluated 280 patients with early-stage (Tis-2N0M0) breast cancer (including 100 hypofractionated RT patients) with regards to treatment outcomes according to the RT schedule. The median whole-breast RT dose was 42.56 Gy/16 fractions for hypofractionated RT and 50.4 Gy/28 fractions for conventional RT. Most patients (n = 260, 92.9%) additionally received a tumor bed boost RT. We used propensity score matching (PSM) analysis to balance the baseline risk factors for recurrence. The co-primary endpoints of this study were disease-free survival (DFS) and ipsilateral breast tumor recurrence (IBTR).DFS or IBTR was analyzed using the Kaplan-Meier survival curve and log-rank test. @*Results@#Total 89 pairs of matched patients (1:1 matching, n = 178) were finally evaluated.The median follow-up was 23.6 months. After matching, the 3-year DFS was 100% in the hypofractionated RT group and 98.4% in the conventional RT group; there was no significant difference in DFS between the groups (P = 0.374). Furthermore, the IBTR did not differ between the hypofractionated RT and conventional RT groups (P = 0.374) after matching. The 3-year overall survival was not different between two groups (both 100%). Hypofractionated RT saved 26.6% of the total cost of RT compared to conventional RT. Additionally, the acute skin toxicity rate (≥ grade 2) was also not significantly different between the groups (hypofractionated RT: 10.1% vs. conventional RT: 2.2%). @*Conclusion@#Hypofractionated RT showed good IBTR and DFS, which were compatible to those in conventional RT in breast cancer. Hypofractionated RT is expected to be used more widely because of its low cost and convenience.

ABSTRACT

Purpose@#In this trial, we investigated the efficacy and safety of adjuvant letrozole for hormone receptor (HR)-positive breast cancer. Here, we report the clinical outcome in postmenopausal women with HR-positive breast cancer treated with adjuvant letrozole according to estrogen receptor (ER) expression levels. @*Methods@#In this multi-institutional, open-label, observational study, postmenopausal patients with HR-positive breast cancer received adjuvant letrozole (2.5 mg/daily) for 5 years unless they experienced disease progression or unacceptable toxicity or withdrew their consent. The patients were stratified into the following 3 groups according to ER expression levels using a modified Allred score (AS): low, intermediate, and high (AS 3–4, 5–6, and 7–8, respectively). ER expression was centrally reviewed. The primary objective was the 5-year disease-free survival (DFS) rate. @*Results@#Between April 25, 2010, and February 5, 2014, 440 patients were enrolled. With a median follow-up of 62.0 months, the 5-year DFS rate in all patients was 94.2% (95% confidence interval [CI], 91.8–96.6). The 5-year DFS and recurrence-free survival (RFS) rates did not differ according to ER expression; the 5-year DFS rates were 94.3% and 94.1%in the low-to-intermediate and high expression groups, respectively (p = 0.6), and the corresponding 5-year RFS rates were 95.7% and 95.4%, respectively (p = 0.7). Furthermore, 25 patients discontinued letrozole because of drug toxicity. @*Conclusion@#Treatment with adjuvant letrozole showed very favorable treatment outcomes and good tolerability among Korean postmenopausal women with ER-positive breast cancer, independent of ER expression.

ABSTRACT

Purpose@#Although drug-coated balloon (DCB) treatment is known to be effective for de novo lesions, the influence of sex on angiographic and clinical outcomes remains unknown. This study aimed to investigate the angiographic and clinical impact of DCB treatment in patients with de novo coronary lesions according to sex. @*Materials and Methods@#A total of 227 patients successfully treated with DCB were retrospectively enrolled and divided into two groups according to sex. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF), which included cardiac death, target vessel myocardial infarction, target lesion revascularization, and target vessel thrombosis. @*Results@#The study enrolled 60 women (26.4%) and 167 men (73.6%). Compared to men, women had a smaller vessel size, larger DCB to reference vessel ratio, and more dissections after DCB treatment (55.0% vs. 37.1%, p=0.016). Women also had a significantly higher LLL compared to men (0.12±0.26 mm vs. 0.02±0.22 mm, p=0.012) at the 6-month follow-up angiography. During a median follow-up of 3.4 years (range 12.7–28.9 months), TVF was similar (women 6.7% vs. men 7.8%, p=0.944). In multivariable analysis, women were independently associated with a higher LLL. @*Conclusion@#LLL was higher in women, but there was no difference in TVF between women and men. Based on multivariable analysis, the women sex was an independent predictor of higher LLL (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

ABSTRACT

Purpose@#This study was conducted to evaluate prognosis of patients with level I/II axillary lymph node metastases from occult breast cancer (OBC). @*Materials and Methods@#Data of 53 patients with OBC who received axillary lymph node dissection (ALND) positiveegative (+/–) breast-conserving surgery between 2001 and 2013 were retrospectively collected at seven hospitals in Korea. The median number of positive lymph nodes (+LNs) was 2. Seventeen patients (32.1%) had >3 +LNs. A total of 48 patients (90.6%) received radiotherapy. Extents of radiotherapy were as follows: whole-breast (WB; n = 11), regional lymph node (RLN; n = 2), and WB plus RLN (n = 35). @*Results@#The median follow-up time was 85 months. Recurrence was found in four patients: two in the breast, one in RLN, and one in the breast and RLN. The 5-year and 7-year disease-free survival (DFS) rates were 96.1% and 93.5%, respectively. Molecular subtype and receipt of breast radiotherapy were significantly associated with DFS. Patients with estrogen receptor negative, progesterone receptor negative, and human epidermal growth factor receptor 2 negative (ER-/PR-/HER2-) subtype had significantly lower 7-year DFS than those with non-ER-/PR-/HER2- tumor (76.9% vs. 100.0%; p = 0.03). Whole breast irradiation (WBI) was significantly associated with a higher 7-year DFS rate (94.7% for WBI group vs. 83.3% for non-WBI group; p = 0.01). Other factors including patient’s age, number of +LNs, taxane chemotherapy, and RLN irradiation were not associated with DFS. @*Conclusion@#Patients with OBC achieved favorable outcome after ALND and breast-targeting treatment. Molecular subtype and receipt of WBI was significant factors for DFS.

ABSTRACT

Background and Objectives@#To evaluate the cost-effectiveness of routine hypertension (HTN) screening as a part of the national health-screening program. @*Methods@#Two aspects of cost-effectiveness were examined using the national general healthscreening program. First, the cost of case-finding was computed for 5-year interval age groups. Second, the cost per quality adjusted life years (QALYs) gained were estimated for 12 different scenarios varying examination starting age, pattern and interval compared with no screening. @*Results@#The cost of finding one new HTN case was low as 26,284 Korean won (KRW) (approximately [approx.] United States Dollar 21) for 70–79 years old to as high as 70,552 KRW for 40–44 years old. Compared with no screening, the costs per QALYs of the following screening strategies were below the incremental cost-effectiveness ratio threshold (approx.KRW 30.5 million): first screening examination with the second confirmatory examination in adults aged ≥40 years every 3 years (KRW 10.2 million), every 2 years (KRW 13.2 million), or annually (KRW 19.9 million). One-way sensitivity analyses suggest that the results were mostly influenced by the sensitivity of the first screening examination, followed by the examination rate of the second confirmatory examination. @*Conclusions@#HTN screening as a part of routine national health screening program was cost-effective for adults aged 40 years or older. The most cost-effective HTN screening strategy was the first screening examination with the second confirmatory examination in aged 40 years or older every 3 years.

ABSTRACT

Background and Objectives@#The alar-columellar relationship plays an important role in the esthetic balance of the nose. We analyzed alar rim deformities and aesthetic concerns and expectations among patients by deformity type in Korean primary rhinoplasty patients. @*Materials and Methods@#Retrospective photographic analysis was done on 336 patients planning to undergo primary rhinoplasty at Kyung Hee University Hospital at Gangdong. We categorized their alar rim deformities as normal, hanging columella, retracted columella, hanging ala, retracted ala, convex ala, concave ala, thick ala, and a combination of the above. Patients’ aesthetic concerns and expectations about their nose were analyzed by preoperative questionnaire. @*Results@#Of the enrolled patients, 38 (11.3%) had no alar rim deformities, and the other 298 patients (88.7%) had one or more deformities. The most prevalent alar rim deformity was hanging ala (59.2%), followed by convex ala (53.3%) and thick ala (32.1%). Male patients were more likely to have convex ala and retracted columella than female patients. More than one-half of the patients (64.1%) had two or more deformities and tended to be young (p=0.028). Patients with thick ala had several reasons for being dissatisfied with their nose and various demands for correction. @*Conclusion@#Distinctive characteristics of alar rim deformities should be considered in surgical planning in order to obtain satisfactory results in Korean primary rhinoplasty patients.

ABSTRACT

Purpose@#Acute kidney injury (AKI) is an uncommon but serious complication after trauma. The objective of this study was to evaluate the clinical characteristics, risk factors, and outcomes of AKI after trauma. @*Methods@#A retrospective cohort study of 386 trauma patients who visited the emergency department at the Asan Medical Center between January 2012 and December 2013 was performed. There were 322 patients included in this study. Patients were assigned into the AKI group and no AKI group. Regression analysis was performed to identify the factors associated with development of AKI following trauma. @*Results@#The overall incidence of AKI following trauma was 6%. There was no difference in patients`age, sex, and body weight between groups. Whereas there was a significant difference in Injury Severity Score, Glasgow Coma Scale, presence of shock, need for a transfusion, lactic acid levels, and severe rhabdomyolysis. In multivariate analysis, the independent risk factors associated with AKI after trauma included the Injury Severity Score [odds ratio (OR) = 1.065, p < 0.01], presence of shock (OR = 3.949, p = 0.012), and severe rhabdomyolysis (OR = 4.475, p < 0.01). Patients in the AKI group were classified (according to the RIFLE criteria) as at Risk in 9 cases (43%), Injury present in 3 (14%), Failure in 7 (33%), Loss in 0 (0%) and End-stage in 2 (10%). Renal replacement therapy was required for 10 patients (47%) in the AKI group and 4 of them (40%) underwent successful weaning. Hospital mortality rate was higher in the AKI group (5/21, 23%) than the no AKI group (3/301, 1% ; p < 0.01). @*Conclusion@#The development of AKI was associated with the severity of trauma, and trauma increased mortality rates.

ABSTRACT

OBJECTIVES@#Secondhand smoke is an issue that cannot be ignored due to its various negative effects. Especially, secondhand smoke inside the household is an area where health policy must pay attention as it can affect all age groups. This study aims to identify the factors associated with smoking inside the household focusing on socioeconomic status in Korea. @*METHODS@#We used data from the Community Health Survey of 2017 and a total of 33,462 participated in the study. Data were analyzed through IBM SPSS version 25.0 to conduct binary logistic regression analysis. @*RESULTS@#Results indicated that indoor smoking had a significant association with socioeconomic status. This association was more marked in those participants who had low household income or those with elementary school education level or less. Furthermore, the study indicates that when the smoker is a woman, older, has higher stress, and is a heavier smoker, the probability of her smoking inside the house is higher. @*CONCLUSIONS@#Based on the results, it is meaningful that this study has found the factors of smoking inside household. The result identify the factors associated with indoor smoking at home, and it can be used as baseline data for developing new smoking cessation policies.

ABSTRACT

Hereditary breast cancer is known for its strong tendency of inheritance. Most hereditary breast cancers are related to BRCA1/BRCA2 pathogenic variants. The lifelong risk of breast cancer in pathogenic BRCA1 and BRCA2 variant carriers is approximately 65% and 45%, respectively, whereas that of ovarian cancer is estimated to be 39% and 11%, respectively. Therefore, understanding these variants and clinical knowledge on their occurrence in breast cancers and carriers are important. BRCA1 pathogenic variant breast cancer shows more aggressive clinicopathological features than the BRCA2 pathogenic variant breast cancer. Compared with sporadic breast cancer, their prognosis is still debated. Treatments of BRCA1/BRCA2 pathogenic variant breast cancer are similar to those for BRCA-negative breast cancer, mainly including surgery, radiotherapy, and chemotherapy. Recently, various clinical trials have investigated poly (adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitor treatment for advanced-stage BRCA1/BRCA2 pathogenic variant breast cancer. Among the various PARP inhibitors, olaparib and talazoparib, which reached phase III clinical trials, showed improvement of median progression-free survival around three months. Preventive and surveillance strategies for BRCA pathogenic variant breast cancer to reduce cancer recurrence and improve treatment outcomes have recently received increasing attention. In this review, we provide an information on the clinical features of BRCA1/BRCA2 pathogenic variant breast cancer and clinical recommendations for BRCA pathogenic variant carriers, with a focus on treatment and prevention strategies. With this knowledge, clinicians could manage the BRCA1/BRCA2 pathogenic variant breast cancer patients more effectively.

ABSTRACT

Purpose@#We aimed to analyze the treatment outcomes of ipsilateral cervical lymph node (CLN)-positive breast cancer without other distant metastasis and compare the outcomes with those of supraclavicular lymph node (SCL)-positive breast cancer. @*Methods@#Seventy-eight patients with breast cancer and ipsilateral CLN metastasis above the supraclavicular fossa (CLN[+] group) were treated at 7 institutions (2000–2014). Seventy-four patients received systemic chemotherapy and breast surgery followed by locoregional radiotherapy. Outcomes of the CLN(+) group were compared with those of the SCL(+) group, which included 183 patients with SCL involvement. @*Results@#The median follow-up duration was 55.9 months. Twenty-two regional failures were found in 15 patients—axillary lymph node (LN) in 8, SCL in 6, internal mammary LN in 3, previously involved CLN in 4, and previously uninvolved ipsilateral CLN in one patient. The 5-year overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS), and distant metastasis-free survival (DMFS) rates were 68.6%, 46.7%, 68.4%, and 57.0%, respectively. Neck dissection did not improve LRRFS and DFS (p = 0.86 and p = 0.26, respectively). Multivariate analysis showed that hormone receptor negativity and the presence of extracapsular extension were prognostic factors for poor DFS. On comparison with stage IIIC using propensity score matching, survival outcomes of the CLN(+) and SCL(+) groups were not different (5-year OS, p = 0.75; DFS, p = 0.88; LRRFS, p = 0.86; and DMFS, p = 0.45). @*Conclusion@#The comparable clinical outcomes indicate that patients with breast cancer who have ipsilateral CLN metastasis without other distant metastasis may benefit from locoregional treatment of the ipsilateral breast and systemic therapies, as do those with N3c disease.

ABSTRACT

Background@#As the population is aging, chronic diseases and depression are becoming the main problems in a country’s healthcare system. In this study, we aimed to explore the associations between chronic diseases and depression among the elderly in South Korea. @*Methods@#We analyzed 9,975 (men, 4,147; women, 5,828) respondents obtained from the 2014 National Survey of Living Conditions and Welfare Needs of Korean Older Persons. Our dependent variable was either 1 or 0 according to whether a respondent had depression or not, where depression was defined when the Short Form of Geriatric Depression Scale score was 8 or more points. Variables of interest were 24 types of chronic diseases and covariates included various socio-demographic and health behavior characteristics. We performed Rao-Scott chi-square tests and hierarchal logistic regression analyses by gender, reflecting the characteristics of the survey. @*Results@#A significant difference was found in the proportion of having depression between genders (men 18.9% vs. women 23.4%). According to fully adjusted, multivariable analyses, for elderly men, relative to those without any chronic disease, the odds ratio of depression was 1.56 (95% confidence interval [CI], 1.10–2.22) in the stroke patients group and 1.82 (95% CI, 1.01–3.25) in the osteoporosis patients group. For elderly women, the odds ratio was 1.96 (95% CI, 1.28–3.00) in the fracture/dislocation and aftereffects patients group and 1.30 (95% CI, 1.03–1.64) in the group of patients with other diseases. @*Conclusion@#Even after being adjusted for diverse characteristics, some chronic diseases were significantly associated with depression in the elderly and the association differed between genders. Therefore, public health and medical interventions are needed to manage such chronic diseases together with curing depression symptoms.

ABSTRACT

Purpose@#Dissection after plain balloon angioplasty is required to achieve adequate luminal area; however, it is associated with a high risk of vascular events. This study aimed to examine the relationship between non-flow limiting coronary dissections and subsequent lumen loss and long-term clinical outcomes following successful drug-coated balloon (DCB) treatment of de novo coronary lesions. @*Materials and Methods@#A total of 227 patients with good distal flow (Thrombolysis in Myocardial Infarction flow grade 3) following DCB treatment were retrospectively enrolled and stratified according to the presence or absence of a non-flow limiting dissection. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF, a composite of cardiac death, target vessel myocardial infarction, target vessel revascularization, and target vessel thrombosis). @*Results@#The cohort consisted of 95 patients with and 132 patients without a dissection. There were no between-group differences in LLL (90.8%) returning for angiography at 6 months (0.05±0.19 mm in non-dissection and 0.05±0.30 mm in dissection group, p= 0.886) or in TVF (6.8% in non-dissection and 8.4% in dissection group, p=0.799) at a median follow-up of 3.4 years. In a multivariate analysis, the presence of dissection and its severity were not associated with LLL or TVF. Almost dissections (93.9%) were completely healed, and there was no newly developed dissection at 6-month angiography. @*Conclusion@#The presence of a dissection following successful DCB treatment of a de novo coronary lesion may not be associated with an increased risk of LLL or TVF (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).

ABSTRACT

Objective@#Cardiovascular diseases are representative risk factors for the onset of cognitive decline. The purpose of this study was to confirm the relationship between diastolic blood pressure and cognitive function in elderly people in Korea. @*Methods@#Data from subjects who were enrolled in the prospective Korean Longitudinal Study on Cognitive Aging and Dementia were used in this study. Data from 701 subjects whose diastolic blood pressure range did not change (≤79 mm Hg or ≥80 mm Hg) over 2 years were analyzed. To analyze the differences in cognitive function between the groups at the 2-year follow-up, an analysis of covariance was performed with covariates, which were significantly different between the two groups, and the baseline cognitive function. @*Results@#Significant differences were observed between the two groups, and the mean scores on the constructional praxis (η2=0.010) and word list recall tests (η2=0.018) in the diastolic blood pressure ≥80 mm Hg group were higher than those in the diastolic blood pressure ≤79 mm Hg group at the 2-year follow-up. @*Conclusion@#These results indicate that maintaining a DBP below 79 mm Hg presents a greater risk of cognitive decline in Korean elderly people.
