ABSTRACT

BACKGROUND@#Decellularized extracellular matrix (dECM) is a non-cellular scaffold with various functions in tissue engineering and regenerative medicine. Elastin is related to tissue elasticity and scarless wound healing, abundantly found in lung and blood vessel tissues. We studied the characteristics of blood vessel-derived dECM (VdECM) and its effect in wound healing. @*METHODS@#VdECM was prepared from porcine blood vessel tissue. Weight percentages of elastin of VdECM and atelocollagen were analyzed. Migratory potential of VdECM was tested by scratch assay. VdECM in hydrogel form was microscopically examined, tested for fibroblast proliferation, and examined for L/D staining. Cytokine array of various growth factors in adipocyte-derived mesenchymal stem cell (ASC) media with VdECM was done. Animal wound model showed the wound healing effect of VdECM hydrogel in comparison to other topical agents. @*RESULTS@#VdECM contained 6.7 times more elastin than atelocollagen per unit weight. Microscopic view of 0.35% VdECM hydrogel showed consistent distribution. Compared to 3% atelocollagen, 0.35% VdECM showed superior results in fibroblast migration. Fluorescent microscopic findings of L/D assay had highest percentage of cell survival in 1% VdECM compared to atelocollagen. Growth factor expression was drastically amplified when VdECM was added to ASC media. In the animal study model, epithelialization rate in the VdECM group was higher than that of control, oxytetracycline, and epidermal growth factor ointments. @*CONCLUSION@#VdECM contains a high ratio of elastin to collagen and amplifies expressions of many growth factors. It promotes fibroblast migration, proliferation, and survival, and epithelialization comparable to other topical agents.

ABSTRACT

Objectives@#The purpose of this study is to analyze the prevalence and factors of depression among the elderly population, a significant issue in Korea’s aging society. We aim to provide basic indicators for improving mental health and quality of life. @*Methods@#From February to December 2021, a study was conducted on a population of 19,158 elderly individuals aged 65 and above residing in Gyeongsangbuk-do province. The severity of depression was evaluated using the Korean version of the Patient Health Questionnaire (PHQ)-9. In addition, demographic information was collected to analyze factors that may influence depression. @*Results@#In the PHQ-9 screening, the average score was 3.65. The results showed that 13,705 individuals (71.5%) were in the normal group with scores ranging from 0 to 4, 3,683 individuals (19.2%) were in the mild group with scores ranging from 5 to 9, 1,575 individuals (8.2%) were in the moderate group with scores ranging from 10 to 19, and 195 individuals (1.0%) were in the severe group with scores of 20 or higher. It was found that place of residence, education level, type of housing, top two difficulties in daily life, subjective economic status, desired services, subjective mental health, past and current history of mental health treatment, and medication for physical illness had statistically significant effects on depression. @*Conclusions@#Various factors were found to have a significant impact on depression among the elderly population in Gyeongsangbuk-do. Proactive prevention and treatment tailored to the population characteristics of the region may be necessary.

ABSTRACT

Hepatocellular carcinoma (HCC) is a highly aggressive disease that is usually diagnosed at an advanced stage. Advanced HCC has limited treatment options and often has a poor prognosis. For the past decade, tyrosine kinase inhibitors have been the only treatments approved for advanced HCC that have shown overall survival (OS) benefits; however, but their clinical efficacy has been limited. Recent trials have demonstrated promising advancements in survival outcomes through immunotherapy-based treatments, such as combinations of immune checkpoint inhibitors (ICIs) with other ICIs, antiangiogenic drugs, and locoregional therapies. The atezolizumab-bevacizumab and durvalumab-tremelimumab (STRIDE) regimen has significantly improved survival rates as a first-line treatment and has become the new standard of care. Therefore, combined treatments for advanced HCC can result in better treatment outcomes owing to their synergistic effects, which requires a multidisciplinary approach. Ongoing studies are examining other therapeutic innovations that can improve disease control and OS rates. Despite improvements in the treatment of advanced HCC, further studies on the optimal treatment selection and sequences, biomarker identification, combination approaches with other therapies, and development of novel immunotherapy agents are required. This review presents the current treatment options and clinical data of the ICI-based combination immunotherapies for advanced HCC from a multidisciplinary perspective.

ABSTRACT

Background/Aims@#The histologic status of the immune-tolerant (IT) phase of chronic hepatitis B relative to long-term outcomes is unclear. This study aimed to discover how the serological criteria currently in use correspond to histologic criteria in determining the IT phase and indication for liver biopsy. @*Methods@#Patients in the serological IT phase determined by positive hepatitis B e antigen, hepatitis B virus (HBV) DNA ≥106 IU/mL, and normal or minimally elevated alanine aminotransferase (ALT) ≤60 IU/L, who underwent liver biopsy at three different hospitals were included. The distribution of the histologic IT phase, defined as fibrosis of stage 1 or less and inflammation of grade 1 or less, was compared with that of the serological IT phase. The risk factors for the incidence of liver-related events, such as hepatocellular carcinoma, liver cirrhosis, liver transplantation, and death, were also analyzed. @*Results@#Eighty-two (31.7%) out of 259 clinically suspected IT phase patients belonged to the histologic IT phase. Age over 35, high AST, and low albumin were useful for ruling out the histologic IT phase. Risk factors predicting liver-related events were age and significant fibrosis stage. There was no significant difference in the proportion of histologic IT phase and clinical prognosis between normal ALT and mildly elevated ALT groups. However, even in patients with normal ALT, age was an important factor in predicting the presence of the histologic IT phase. @*Conclusions@#A significant number of patients who belonged to the serological IT phase were not in the histologic IT phase. Patients over 35 years and those with high AST, low albumin, and low HBV DNA levels were more likely to experience poor long-term clinical outcomes. Therefore, additional histologic assessment should be considered.

ABSTRACT

Purpose@#Patient-derived tumor cells can be a powerful resource for studying pathophysiological mechanisms and developing robust strategies for precision medicine. However, establishing organoids from patient-derived cells is challenging because of limited access to tissue specimens. Therefore, we aimed to establish organoids from malignant ascites and pleural effusions. @*Materials and Methods@#Ascitic or pleural fluid from pancreatic, gastric, and breast cancer patients was collected and concentrated to culture tumor cells ex vivo. Organoids were considered to be successfully cultured when maintained for five or more passages. Immunohistochemical staining was performed to compare the molecular features, and drug sensitivity was assayed to analyze the clinical responses of original patients. @*Results@#We collected 70 fluid samples from 58 patients (pancreatic cancer, n=39; gastric cancer, n=21; and breast cancer, n=10). The overall success rate was 40%; however, it differed with types of malignancy, with pancreatic, gastric, and breast cancers showing 48.7%, 33.3%, and 20%, respectively. Cytopathological results significantly differed between successful and failed cases (p=0.014). Immunohistochemical staining of breast cancer organoids showed molecular features identical to those of tumor tissues. In drug sensitivity assays, pancreatic cancer organoids recapitulated the clinical responses of the original patients. @*Conclusion@#Tumor organoids established from malignant ascites or pleural effusion of pancreatic, gastric, and breast cancers reflect the molecular characteristics and drug sensitivity profiles. Our organoid platform could be used as a testbed for patients with pleural and peritoneal metastases to guide precision oncology and drug discovery.

ABSTRACT

FLASH radiotherapy (FLASH RT) is a technique to deliver ultra-high dose rate in a fraction of a second. Evidence from experimental animal models suggest that FLASH RT spares various normal tissues including the lung, gastrointestinal track, and brain from radiation-induced toxicity (a phenomenon known as FLASH effect), which is otherwise commonly observed with conventional dose rate RT. However, it is not simply the ultra-high dose rate alone that brings the FLASH effect. Multiple parameters such as instantaneous dose rate, pulse size, pulse repetition frequency, and the total duration of exposure all need to be carefully optimized simultaneously. Furthermore it is critical to validate FLASH effects in an in vivo experimental model system. The exact molecular mechanism responsible for this FLASH effect is not yet understood although a number of hypotheses have been proposed including oxygen depletion and less reactive oxygen species (ROS) production by FLASH RT, and enhanced ability of normal tissues to handle ROS and labile iron pool compared to tumors. In this review, we briefly overview the process of ionization event and history of radiotherapy and fractionation of ionizing radiation. We also highlight some of the latest FLASH RT reviews and results with a special interest to neurocognitive protection in rodent model with whole brain irradiation. Lastly we discuss some of the issues remain to be answered with FLASH RT including undefined molecular mechanism, lack of standardized parameters, low penetration depth for electron beam, and tumor hypoxia still being a major hurdle for local control. Nevertheless, researchers are close to having all answers to the issues that we have raised, hence we believe that advancement of FLASH RT will be made more quickly than one can anticipate.

ABSTRACT

Maintaining the patency of the external auditory canal (EAC) during reconstruction is important because of its physiological role in hearing and immunological protective functions. The curved shape of the EAC presents a challenge when performing a skin graft. One of the key points for a successful skin graft is to ensure compression on the wound bed, and many novel methods, including prefabricated ear molds, have been reported for this purpose. In this study, we present a case of a skin graft performed to reconstruct a skin defect following excision of actinic keratosis in the EAC, using the cover of an ear thermometer probe as a mold for the graft to match the curvature of the EAC. This is an economical and practical method for secure compression dressing of a skin graft in the EAC.

ABSTRACT

Background@#Primary adrenal (PA) diffuse large B cell lymphoma (DLBCL) was previously reported as an aggressive subset of DLBCL, but its genetic features were not sufficiently characterized. From our previous study of DLBCL with programmed death-ligand 1 (PD-L1) gene alterations, we focused on PD-L1 gene alterations in PA-DLBCL with clinicopathologic implications. @*Methods@#We performed fluorescence in situ hybridization for PD-L1 gene translocation and amplification in PA-DLBCL (n = 18) and comparatively analyzed clinicopathologic characteristics with systemic non-adrenal (NA)-DLBCL (n = 90). @*Results@#PA-DLBCL harbored distinctive features (vs. NADLBCL), including high international prognostic index score (3–5) (72% [13/18] vs. 38% [34/90], p = .007), poor Eastern Cooperative Oncology Group performance score (≥ 2) (47% [7/15] vs. 11% [10/90], p = .003), elevated serum lactate dehydrogenase (LDH) (78% [14/18] vs. 51% [44/87], p = .035) and MUM1 expression (87% [13/15] vs. 60% [54/90], p = .047). Moreover, PA-DLBCL showed frequent PD-L1 gene alterations (vs. NA-DLBCL) (39% [7/18] vs. 6% [5/86], p = .001), including translocation (22% [4/18] vs. 3% [3/87], p = .016) and amplification (17% [3/18] vs. 2% [2/87], p = .034). Within the PA-DLBCL group, PD-L1 gene–altered cases (vs. non-altered cases) tended to have B symptoms (p = .145) and elevated LDH (p = .119) but less frequent bulky disease (≥ 10 cm) (p = .119). In the survival analysis, PA-DLBCL had a poor prognosis for overall survival (OS) and progression-free survival (PFS) (vs. NA-DLBCL; p = .014 and p = .004). Within the PA-DLBCL group, PD-L1 translocation was associated with shorter OS and PFS (p < .001 and p = .012). @*Conclusions@#PA-DLBCL is a clinically aggressive and distinct subset of DLBCL with frequent PD-L1 gene alterations. PD-L1 gene translocation was associated with poor prognosis in PA-DLBCL.

ABSTRACT

Globally, chronic diseases have a high burden and are a significant factor affecting society, such as through economic productivity and deepening social inequality. Deaths from chronic diseases in Korea accounted for 79.6% of all deaths as of 2021, and medical expenses from chronic diseases in Korea accounted for 85.0% of all national medical expenses as of 2020. Since the 1970s, chronic disease management in Korea has focused on projects such as acute infectious diseases, maternal and child health, and family planning by region, sporadically centered on universities. Since then, the importance of prevention and management of chronic diseases has been highlighted, and a comprehensive plan for national health promotion was established in 2002 to provide policy support. Here, we looked at the progress of the chronic disease management project and its effects and review suggestions for efficient establishment of a primary medical chronic disease management project to be carried out in the future.

ABSTRACT

Background@#Self-leadership, an action strategy that can maximize individual capabilities, can affect the organizational commitment of dental hygienists and ultimately improve the quality of medical services. This study aims to demonstrate the need for self-leadership and organizational commitment for dental hygienists and develop measures to improve the quality of medical services. @*Methods@#An online survey of dental hygienists working at dental hospitals and clinics in Seoul and Gyeonggi province, Republic of Korea was conducted from March 28 to May 1, 2022. A total of 341 questionnaires were returned and analyzed. The measurement tools were modified and supplemented based on the theories and models developed by Manz for self-leadership, Mowday for organizational commitment, and Cronin and Taylor for medical services. Descriptive statistics, independent t-tests, ANOVA, simple regression, and multiple regression analyses were performed using SPSS 25.0. @*Results@#In leadership education, self-leadership is based on participation experience, the number of participants, and when and where it is received. Organizational commitment comes from participation experience, and the quality of medical services has been found to affect participation experience and location. Self-leadership had an effect on the quality of medical services (β=0.497, t=10.551, p<0.001; β =0.599, t=13.783, p<0.001; β=0.353, t=7.601, p<0.001) and organizational commitment was found to have a mediating effect. @*Conclusion@#Dental hygienists’ self-leadership has a positive effect on the quality of medical services through the formation of appropriate interrelationships within the organization. Therefore, self-leadership programs should be developed, participated in, and promoted to improve the self-leadership of dental hygienists. Moreover, hospitals should improve their environment to provide and improve self-leadership education.

ABSTRACT

Objectives@#This study aimed to identify the socioeconomic factors related to tooth brushing behavior among adults in Korea. @*Methods@#This cross-sectional study used data from the Korea Community Health Survey (KCHS) in 2019. Respondents aged 19 years and older (n=299,099) comprised the study sample. The dependent variable was tooth brushing behavior, whereas the independent variables were demographic and socioeconomic factors. The data were processed using chi-squared test, independent t-test, ANOVA, and adjusted multiple logistic regression analysis were performed. Statistical analysis was performed using the STATA 17.0 program, with significance set at the 5% level. @*Results@#About half (55%) of the respondents brushed their teeth at least twice a day. The findings also revealed significant differences according to socioeconomic status (P<.01). Those who brushed their teeth less than twice a day had the following characteristics: men, aged 45 years or older, low income, working outside, less educated, without a spouse, and living in rural areas. Adjusted multiple logistic regression analysis showed that the area of residence contributed to tooth brushing behavior. @*Conclusions@#The area of residence, as well as socioeconomic status, should be considered in oral health education and intervention strategies.

ABSTRACT

Implant placement may be restricted by anatomical and/or financial limitations in restoring a completely edentulous arch, or the patients’ unwillingness to have extensive surgical procedures. Implant assisted removable partial dentures (IARPD) in combination with anterior fixed implant prostheses can be proposed as an alternative treatment option for the restoration of a completely edentulous arch. In this case, a 56-year-old female patient who has a fully edentulous maxilla opposed by partially edentulous mandible was treated. The treatment option for the maxilla consisted of an implant-assisted removable partial denture supported by four anterior fixed implant prostheses. The mandible was restored with 8 anterior fixed partial dentures and posterior fixed implant-supported prostheses.Long-term follow-up and supportive periodontal treatment were performed for 9years, and the patient was satisfied with the overall appearance as well as masticatory function.

ABSTRACT

Acute myeloid leukemia (AML) is a common hematologic malignancy with high mortality and a short survival period in adults. About 10% of these cases, called therapy-related AML, are reported to be the consequence of chemotherapy or radiotherapy of previous malignancy. In a clinical setting, this is usually diagnosed by peripheral blood smear or bone marrow biopsy by assessing the proportion of blasts. However, postmortem blood samples are not suitable for smear analysis because of hemolysis. Therefore, ancillary tests for identifying leukemic infiltration or related molecular change can provide an alternative diagnostic clue for AML. The deceased had been treated for 3 years for a combined type of hepatocellular carcinoma with multiple pulmonary metastases. Treatments included the resections of primary and metastatic tumors, chemotherapy, and radiotherapy, which prevented further progression of his cancer. One year after the last treatment, he suddenly collapsed without any specific symptoms and shortly died. The microscopic examination of the autopsy samples revealed extensive extramedullary infiltration of leukemia, which was confirmed as an AML by a series of ancillary immunohistochemical staining. This case illustrates both the importance of careful hematologic observation in cancer survivors and the necessity of a detailed medical diagnosis in a medicolegal autopsy.

ABSTRACT

Group 3 innate lymphoid cells (ILC3), which express IL-22 and IL-17A, has been introduced as one of pathologic cells in axial spondyloarthritis (axSpA). Dyslipidaemia should be managed in axSpA patients to reduce cardiovascular disease, and dyslipidaemia promotes inflammation. This study aimed to reveal the role of circulating ILC3 in axSpA and the impact of dyslipidaemia on axSpA pathogenesis. AxSpA patients with or without dyslipidaemia and healthy control were recruited. Peripheral blood samples were collected, and flow cytometry analysis of circulating ILC3 and CD4+ T cells was performed. The correlation between Ankylosing Spondylitis Disease Activity Score (ASDAS)-C-reactive protein (CRP) and circulating immune cells was evaluated. The effect of oxidized low-density lipoprotein cholesterol (oxLDL-C) on immune cell differentiation was confirmed. AxSpA human monocytes were cultured with with oxLDL-C, IL-22, or oxLDL-C plus IL-22 to evaluate osteoclastogenesis using tartrate-resistant acid phosphatase (TRAP) staining and realtime quantitative PCR of osteoclast-related gene expression. Total of 34 axSpA patients (13 with dyslipidaemia and 21 without) were included in the analysis. Circulating IL-22+ ILC3 and Th17 were significantly elevated in axSpA patients with dyslipidaemia (p=0.001 and p=0.034, respectively), and circulating IL-22+ ILC3 significantly correlated with ASDAS-CRP (Rho=0.4198 and p=0.0367). Stimulation with oxLDL-C significantly increased IL-22+ ILC3, NKp44 − ILC3, and Th17 cells, and these were reversed by CD36 blocking agent. IL-22 and oxLDL-C increased TRAP + cells and osteoclast-related gene expression. This study suggested potential role of circulating IL-22+ ILC3 as biomarker in axSpA. Furthermore, dyslipidaemia augmented IL-22+ ILC3 differentiation, and oxLDL-C and IL-22 markedly increased osteoclastogenesis of axSpA.

ABSTRACT

Background@#Keloids can occur anywhere in the human body. They are difficult to remove and can cause distress in patients. Although many options are available to treat keloids, no single method is considered the optimal treatment of choice. The authors encountered cases where an umbilical keloid developed at the trocar site after laparoscopic surgery and managed the keloid using a transposition flap. @*Methods@#A total of 10 umbilical keloid patients treated from 2013 to 2020 were included in this study. All patients developed a keloid due to the placement of a laparoscopic trocar incision port, and their major complaints varied from an asymptomatic nodule to pruritus or pain. All excisions were performed under local anesthesia, and transposition flaps were planned afterward. The surrounding tissue was rearranged so that the shape of the umbilicus was deformed to the minimum extent possible. The keloid scars were examined both preoperatively and 6 months postoperatively using the Patient and Observer Scar Assessment Scale (POSAS). @*Results@#All surgical wounds healed well without complications. The average time interval from laparoscopic surgery to keloid scar revision was 4.3 years. The mean postoperative follow-up period was 10.9 months, and no patient underwent reoperation. Four patients were treated with triamcinolone after surgery due to mild hypertrophy or pruritus. The POSAS observer scale showed significantly decreasing scores over time in all patients (P=0.002). @*Conclusions@#Cosmetically unfavorable keloids that form in the umbilicus following laparoscopic surgery can be improved with a simple procedure using excision and transposition flaps.

ABSTRACT

Background/Aims@#Frailty increases the risks of in-hospital adverse events such as delirium, falls, and functional decline in older adults. We assessed the feasibility and clinical relevance of frailty status in Korean older inpatients using the Clinical Frailty Scale (CFS) and Korean version of the Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight scale (K-FRAIL) questionnaires. @*Methods@#Frailty status was measured using the Korean-translated version of the CFS and K-FRAIL questionnaire within 3 days from admission in 144 consecutive patients aged 60 years or older. The correlation between CFS and K-FRAIL score was assessed. The criterion validity of CFS was assessed using receiver operating characteristic analysis. As outcomes, delirium, bedsore, length of stay (LOS), in-hospital mortality, and unplanned 30-day readmission were measured by reviewing medical records. @*Results@#The mean age of the study population was 70.1 years (range, 60 to 91), and 75 (52.1%) were men. By linear regression analysis, CFS and K-FRAIL were positively correlated (B = 0.72, p < 0.001). A CFS cutoff of ≥ 5 maximized sensitivity + specificity to classify frailty using K-FRAIL as a reference (C-index = 0.893). Higher frailty burden by both CFS and K-FRAIL was associated with higher LOS and bedsores. Unplanned readmission and in-hospital mortality were associated with higher CFS score but not with K-FRAIL score, after adjusting for age, gender, polypharmacy, and multimorbidity. @*Conclusions@#Frailty status by CFS was associated with LOS, bedsores, unplanned readmission, and in-hospital mortality. CFS can be used to screen high-risk patients who may benefit from geriatric interventions and discharge planning in acutely hospitalized older adults.

ABSTRACT

Pandemic of coronavirus disease 2019 (COVID-19) has caused many changes in the healthcare system and patients with preexisting advanced liver disease, notably cirrhosis, are associated with a severe course and a high mortality rate of COVID-19. In patients with liver disease, the underlying liver disease severity is closely related to the prognosis, so appropriate management of liver disease will be one of the most important strategies to protect the patient from COVID-19 infection that may occur in the future. The approach to patient care should be individualized and flexible according to the type and severity of patient’s underlying liver disease, the prevalence of COVID-19, and availability of medical resource. If possible, standard of care for patients with liver disease should be resumed In addition, it is necessary to predict and prepare for the wave of liver disease yet to come after the COVID-19 pandemic.

ABSTRACT

Background@#Dietary supplements (DS) use is known to be common among cancer survivors. However, detailed information on the factors influencing DS use seems insufficient, including cancer-related and psychological factors. @*Methods@#Study subjects were 1,852 Korean adult cancer survivors recruited from cancer survivor clinic of two university-affiliated hospitals. Data were collected retrospectively through review of medical records and self-administered questionnaires. Psychological factors were assessed using Hospital Anxiety and Depression Scale (HADS) and Fear of Cancer Recurrence Inventory-Short Form. Factors associated the DS use were evaluated by multiple logistic regression analysis after adjusting for covariates. @*Results@#The prevalence of long-term DS use was 15.7% in overall (17.5% in female and 11.6% in male). Female survivors were 3.14 times (95% confidence interval [CI], 1.89–5.22) more likely to use DS than male. In male cancer survivors, ever-smoking and previous radiotherapy were positively associated with DS use. In females, breast cancer survivors were 0.32 times less likely to use DS compared with stomach cancer survivors, and survivors with family history of cancer were 1.39 times more likely to use DS than those without. After adjusting for sociodemographic, clinical, and lifestyle factors, survivors with anxiety (HADS ≥8) used DS 1.38 times (95% CI, 1.01–1.91) more frequently, compared with those without anxiety. @*Conclusion@#Diverse factors such as female sex, cancer treatment modality, smoking history, family history and anxiety status were associated with DS use in Korean cancer survivors. Targeted strategies with consideration of these factors are needed for counseling DS use for cancer survivors.

ABSTRACT

The study aimed to review the current postpartum care service system and suggest measures of improvement for the public reinforcement of the private-postpartum care center (PCC). We conducted a review of literature, including an internet search, and we analyzed the in-depth interviews using questionnaires answered by workers from the 6 private-PCCs operated in Goyang city. Using these data, we derived possible measures which could improve the publicity of private-PCCs. It was found that the 11 nationwide public-PCCs had serious operating deficits, and its utilization by the vulnerable was insufficient. In areas where private-PCCs are concentrated, we can propose the following policies to strengthen publicity, rather than establishing another public-PCC. First, it is important to provide support for private-PCCs to apply cost reductions for vulnerable groups, similar to the maternal and newborn medical care of public-PCCs. Second, publicity would be strengthened by reorganizing the pregnancy and childbirth education program, while also offering additional services for mothers with stillbirths and abortions. For the integrated management of postpartum care services, this should be shifted towards reinforcing the publicity of private-PCCs, rather than operating a public-PCC in relatively concentrated private-PCC areas. Through these policies, it is expected that financial and administrative waste will be reduced, and an integrated management system for postpartum care services will be established.

ABSTRACT

Background@#Since September 2015, the initiation of antiviral therapy (AVT) for patients with chronic hepatitis B (CHB)-related cirrhosis has been reimbursed according to the revised Korean Association for the Study of Liver (KASL) guideline, if the patient had hepatitis B virus DNA level ≥ 2,000 IU/L, regardless of aminotransferase or alanine aminotransferase levels. This study investigated whether the KASL guideline implementation reduced the risk of CHB-related hepatocellular carcinoma (HCC) in patients with cirrhosis in South Korea. @*Methods@#A total of 429 patients with CHB-related cirrhosis who initiated AVT between 2014 and 2016 were recruited. The risk of HCC development was compared between patients who initiated AVT before and after September 2015 (pre-guideline [n = 196, 45.7%] vs. postguideline implementation [n = 233, 54.3%]). @*Results@#Univariate analysis showed that AVT initiation before guideline implementation, older age, male gender, and diabetes significantly predicted increased risk of HCC development (all P < 0.05). Subsequent multivariate analysis showed that AVT initiation before guideline implementation (HR = 1.941), older age (HR = 5.762), male gender (HR = 2.555), and diabetes (HR = 1.568) independently predicted increased risk of HCC development (all P < 0.05). Additionally, multivariate analysis showed that AVT initiation before guideline implementation (HR = 2.309), male gender (HR = 3.058), and lower platelet count (HR = 0.989) independently predicted mortality (P < 0.05). The cumulative incidences of HCC and mortality were significantly higher in patients who initiated AVT before guideline implementation than in those who initiated AVT after guideline implementation (all P < 0.05, log-rank test). @*Conclusion@#The prognosis of patients with CHB-related cirrhosis who initiated AVT improved after guideline implementation according to the revised KASL guideline.
