ABSTRACT
Purpose@#The tablet form of tacrolimus is more convenient for drug ingestion than the capsule form. We examined the efficacy and safety of tacrolimus tablets and a satisfaction survey after formula conversion in liver transplant (LT) recipients. @*Methods@#This study was an open-label, prospective clinical trial for tacrolimus formula 1:1 conversion from capsule to tablet in 41 adult LT recipients with tacrolimus maintenance therapy of more than 1 month. The primary endpoint was incidence of biopsy-proven acute rejection (BPAR) within 24 weeks. Surveys 1 week before and 4 weeks after formula conversion were conducted for total daily dose of medication, number, scale of discomfort and satisfaction. @*Results@#The overall incidence of BPAR was 0% and there was no graft loss or patient death. The incidence of adverse effects was 34.1% (n = 14) after formula conversion. The most common severe adverse effect was abnormal liver function test (n = 5): biliary complications (n = 4) and alcoholic recidivism (n = 1). Total daily dose and number of tacrolimus doses were significantly lower after formula conversion (P < 0.05) without changes in trough level. According to survey analysis, there was no significant difference in discomfort and satisfaction scales from capsule to tablet conversion (P < 0.05). @*Conclusion@#The present study suggests that the new tablet formula can be a useful treatment option to maintain a consistent level of tacrolimus with a lower total daily dose and number in adult LT recipients.
ABSTRACT
Purpose@#An increasing number of older patients now undergo liver transplantation (LT). Although the overall outcomes in older patients are not different from those of younger patients, there is no tool to predict LT prognosis in older patients.We hypothesized that a modified Charlson comorbidity index (mCCI) and 5-factor modified frailty index (mFI-5) can predict outcomes in older patients after LT. @*Methods@#This retrospective study included 155 patients (aged >65 years) who underwent LT at Seoul National University Hospital. The recipients were subcategorized into 2 groups based on the mCCI score and mFI-5: the low (0–1) and high (2–5) mCCI groups, and low (≤0.4) and high (>0.4) mFI-5 groups. The independent effect of each variable on post-LT survival was determined using the mCCI subgroup, age at transplantation, sex, Child-Turcotte-Pugh score, model for end-stage liver disease (MELD) score, and mFI-5 subgroup. @*Results@#The high-mCCI group (41 patients) showed significantly lower 1- and 3-month and 1-, 3-, and 5-year survival than the low-mCCI group. Using the Cox regression model, the mCCI, sex, and MELD score remained significant. The mFI-5 was not a significant factor to predict patients’ survival. @*Conclusion@#The mCCI and MELD scores could be used to predict post-LT survival in older patients.
ABSTRACT
Purpose@#Total necrosis of hepatocellular carcinoma (HCC) achieved via locoregional treatment (LRT) is considered to indicate a lack of tumor viability. Nonetheless, there is insufficient evidence of recurrence after liver transplantation (LT) in patients with such a status. The aim of this study was to investigate the prognosis of patients diagnosed with totally necrotic nodules upon explant hepatectomy after LT. @*Methods@#We conducted a retrospective study of patients diagnosed with totally necrotic nodules after LT for HCC. A total of 165 patients with HCC who underwent living- or deceased-donor LT from 2000 to 2020 in our hospital were included. @*Results@#A total of 5 patients (3.0%) exhibited HCC recurrence during a median follow-up of 84 months (range, 4–243 months) after LT. The 5-year overall and recurrence-free survival rates of these patients were 92.8% and 92.2%, respectively. Four patients in the HCC-recurrence group (80.0%) died even after further treatment, including transarterial chemoembolization, surgery, and systemic treatment. Both univariate and multivariate analyses of clinicopathological factors identified a maximum diameter of the totally necrotic nodules of >5 cm as the only factor associated with tumor recurrence following LT (P = 0.005 and P = 0.009, respectively). @*Conclusion@#Total necrosis of HCC via LRT yielded excellent survival outcomes for patients undergoing LT. Nevertheless, patients with large tumors should be considered at high risk of recurrence after LT, suggesting the need for their active surveillance during the follow-up period.
ABSTRACT
Purpose@#Liver grafts from donors with HBV infection contributed to expanding the donor pool under the hepatitis B immunoglobulin and antiviral agents (nucleos(t)ide analogues) in the HBV-endemic area. We report long-term outcomes of liver transplantations (LTs) using grafts from donors with active or chronic HBV infection. @*Methods@#Overall, 2,260 LTs performed in 3 major hospitals in Seoul from January 2000 to April 2019 were assessed for inclusion. Twenty-six grafts (1.2%) were obtained from HBsAg (+), HBeAb (+), or HBcAb (+) donors, and recipient outcomes were retrospectively reviewed. Donor and recipient demographics and transplantation outcomes were analyzed. @*Results@#Sixteen deceased donor LTs were performed using active HBsAg (+) grafts. Ten other LTs were sourced from 10 living donors. There was no significant difference in survival in patients who received deceased donor LTs compared with that in those who underwent LT with non–hepatitis virus-infected grafts. Fourteen patients who were followed up for >5 years were stable, and no difference in hepatocellular carcinoma recurrence rate was observed 5 years after transplantation between transplants from donors with and those without HBV. @*Conclusion@#Considering long-term outcomes, liver grafts from donors with active HBV replication can be safely used for LT.
ABSTRACT
Background@#Due to impaired cell-mediated immunity, solid organ transplantation (SOT) recipients are at increased risk of developing nontuberculous mycobacterial pulmonary disease (NTM-PD). However, the clinical course of NTM-PD in SOT patients and the impact of SOT on the prognosis of NTM-PD remain unclear. @*Methods@#We analyzed patients who developed NTM-PD after receiving SOT between January 2001 and December 2020, at a tertiary referral hospital in South Korea. Baseline characteristics, clinical course, and prognosis were evaluated. Propensity score-matched analysis was performed to assess the impact of SOT on long-term survival in patients with NTM-PD. @*Results@#Among 4,685 SOT recipients over 20 years, 12 patients (median age, 64 years;interquartile range [IQR], 59–67 years; men, 66.7%) developed NTM-PD. Seven (58.3%) and five (41.7%) patients underwent kidney and liver transplantation, respectively, before the diagnosis of NTM-PD. The incidence of NTM-PD was 35.6 cases per 100,000 person-years among kidney transplant recipients and 28.7 cases per 100,000 person-years among liver transplant recipients. The median time between transplantation and the diagnosis of NTMPD was 3.3 (IQR, 1.5–10.8) years. The most common mycobacterial species was Mycobacterium avium (50.0%). Antibiotic treatment was initiated in five (41.7%) patients, and two patients (40.0%) achieved microbiological cure. Two patients died during a median follow-up of 4.2 (IQR, 2.3–8.8) years and NTM-PD was assumed to be the cause of death in one patient. When matched to patients without a history of SOT, patients with a history of SOT did not show worse survival (P value for log-rank test = 0.62). @*Conclusion@#The clinical course of NTM-PD in SOT recipients was comparable to that of patients without SOT, and SOT did not increase the risk of all-cause mortality in patients with NTM-PD.
ABSTRACT
Purpose@#Analyses on pure laparoscopy in donor hepatectomies, including the middle hepatic vein (MHV), are still scarce. This study aimed to compare the outcomes of donor right hepatectomy, including the MHV, when performed laparoscopically with conventional open surgery. @*Methods@#Data from living donors who underwent donor right hepatectomy between January 2012 and December 2020 were retrospectively analyzed. The intraoperative and postoperative complication rates of the pure laparoscopic donor right hepatectomy (PLDRH) with MHV inclusion (PLDRHM) group were compared with the conventional open donor right hepatectomy with MHV inclusion (CDRHM) group and the PLDRH without MHV inclusion [PLDRHM(–)] group. @*Results@#Compared to the CDRHM group, the PLDRHM group had a longer bench time (P < 0.001) and higher Δ%,calculated as [(preoperative value – postoperative value)/preoperative value] × 100, of AST (P < 0.001), ALT (P < 0.001), and total bilirubin (P = 0.023), but shorter hospital stay (P = 0.004) and a lower rate of complications (P = 0.005). Compared to the PLDRHM(–) group, the PLDRHM group had fewer male donors (P < 0.001) and a lower body mass index (P < 0.001), estimated total liver volume (P < 0.001), and real graft weight (P < 0.001). Results of laboratory changes, hospital stays, and complication rates were similar between the 2 groups. @*Conclusion@#PLDRH with the inclusion of the MHV in selected donors and recipients is feasible and safe when performed by surgeons experienced in laparoscopic surgery, with favorable complication rates compared to CDRHM and PLDRHM(–).
ABSTRACT
Purpose@#Intrahepatic cholangiocarcinoma (ICC) has various characteristics according to anatomical, histologic classifications, and its prognoses are different. This study aimed to compare oncologic outcomes according to tumor location (second bile duct confluence) and evaluate the effect of adjuvant chemotherapy. @*Methods@#Clinical data of 318 patients who underwent curative resection for ICC was reviewed. Central type ICC (C-ICC) and peripheral type ICC (P-ICC) were defined when the tumor invades the intrahepatic secondary biliary confluence and when located more peripherally, respectively. @*Results@#A larger tumor size, higher rate of elevated CA 19-9 level, vascular invasion, R1 resection, advanced T stage, and lymph node metastasis were found in C-ICC. C-ICC had poorer overall survival (median, 33 months vs. 58 months; P = 0.001), and the difference was more prominent in the early stage. C-ICC had a higher recurrence rate (68.7% vs. 55.1%, P = 0.014); otherwise, there was no difference in the recurrence patterns. There were no survival benefits of adjuvant chemotherapy in the entire cohort, but there were benefits in advanced stages (T3–4, N1 stage), especially in C-ICC. @*Conclusion@#C-ICC has more aggressive tumor characteristics and poor survival compared to P-ICC. Adjuvant chemotherapy seems to have survival benefits in the advanced stages, especially in the central type.
ABSTRACT
Purpose@#The aim of this study was to compare surgical outcomes after liver resection for hepatocellular carcinoma (HCC) according to tumor size using a large, nationwide cancer registry-based cohort and propensity score matching. @*Methods@#From 2008 to 2015, a total of 12,139 patients were diagnosed with liver cancer and registered in the Korean Primary Liver Cancer Registry. Patients without distant metastasis who underwent hepatectomy as a primary treatment were selected. We performed 1:1 propensity score matching between the small (<5 cm), large (≥5 cm and <10 cm), and huge (≥10 cm) groups. @*Results@#Overall, 265 patients in the small and large groups were compared, and 64 patients each in the large and huge groups were compared. The overall and progression-free survival rates were significantly lower in the large group than in the small group (P < 0.001 and P < 0.001, respectively). Overall survival tended to be poorer in the huge group than in the large group (P = 0.051). The progression-free survival rate was significantly lower in the huge group than in the large group (P = 0.002). @*Conclusion@#Although primary liver resection can be considered even in patients with huge HCC, greater caution with careful screening for recurrence is needed.
ABSTRACT
Background/Aims@#Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer-related death in Korea. This study evaluated the characteristics of Korean patients newly diagnosed with HCC in 2015. @*Methods@#Data from the Korean Primary Liver Cancer Registry (KPLCR), a representative sample of patients newly diagnosed with HCC in Korea, were analyzed. A total of 1,558 patients with HCC registered in the KPLCR in 2015 were investigated. @*Results@#The median age was 61.0 years (interquartile range, 54.0-70.0 years), and men accounted for 79.7% of the subjects. Hepatitis B virus infection was the most common underlying liver disease (58.1%). According to the Barcelona Clinic Liver Cancer (BCLC) staging system, stage 0, A, B, C, and D HCCs accounted for 14.2%, 26.3%, 12.7%, 39.0%, and 7.8% of patients, respectively. Transarterial therapy (29.5%) was the most commonly performed initial treatment, followed by surgical resection (25.1%), best supportive care (20.2%), and local ablation therapy (10.5%). Overall, 42.4% of patients were treated in accordance with the BCLC guidelines: 61.7% in stage 0/A, 39.0% in stage B, 18.1% in stage C, and 71.6% in stage D. The 1-, 3-, and 5-year OS rates were 66.5%, 49.0%, and 17.0%, respectively. @*Conclusions@#In 2015, approximately 40% of Korean HCC cases were diagnosed at a very early or early stage, and 35% of patients underwent potentially curative initial treatment. BCLC guidance was followed in 42.4% of patients; in patients with stage B or C disease, there was relatively low adherence.

ABSTRACT
Background/Aims@#Considering the high prevalence and mortality of hepatocellular carcinoma (HCC) in Korea, accurate statistics for HCC are important. We evaluated the characteristics of Korean patients with newly diagnosed HCC. @*Methods@#We retrospectively evaluated data from the Korean Primary Liver Cancer Registry (KPLCR). The baseline characteristics, treatment modalities, and overall survival (OS) of 4,572 patients with HCC registered in the KPLCR between 2012 and 2014 were investigated. @*Results@#At the time of HCC diagnosis, the median age was 60.0 years, with male predominance (79.6%). Hepatitis B virus infection was the most common etiology (59.1%). The rates of Barcelona Clinic Liver Cancer (BCLC) stages 0, A, B, C, and D at diagnosis were 3.9%, 36.9%, 12.5%, 39.4%, and 7.3%, respectively. The proportion of very early or early stage HCC at diagnosis (BCLC stage 0 or A) in the 2012-2014 cohort was significantly lower than that in the 2008-2011 cohort (40.8% vs. 48.3%, P<0.001). Transarterial therapy (37.5%) was the most commonly performed initial treatment, followed by surgical resection (19.8%), best supportive care (19.1%), and local ablation (10.6%). The median OS was 2.9 years, and the 1-, 3-, and 5-year OS rates were 67.7%, 49.3% and 41.9%, respectively. The OS rate of the 2012-2014 cohort was significantly higher than that of the 2008-2011 cohort (log-rank, P<0.001). @*Conclusions@#The OS of HCC patients registered in the KPLCR between 2012 and 2014 significantly improved. Nevertheless, as about half of the HCC patients were diagnosed at an advanced stage, vigorous and optimized HCC screening strategies should be implemented.
ABSTRACT
Background@#s/Aims: Backgrounds/Aims: In Korea, hepatocellular carcinoma (HCC) is the sixth most common cancer and results in the second-highest cancer death rate among all cancers. We aimed to describe the characteristics of patients who were newly diagnosed with HCC in Korea between 2008 and 2011. @*Methods@#The Korean Primary Liver Cancer Registry (KPLCR) is a random sample consisting of approximately 15% of patients with newly diagnosed primary liver cancer registered in the Korean Central Cancer Registry. We investigated the baseline characteristics, treatment modalities, and overall survival (OS) of patients with HCC registered in the KPLCR between 2008 and 2011. @*Results@#A total of 6,083 patients were histologically or radiologically diagnosed with HCC. The hepatitis B virus was the predominant HCC etiology (72.0%). According to the Barcelona Clinic Liver Cancer (BCLC) staging system, stages 0, A, B, C, and D accounted for 8.6%, 39.7%, 11.5%, 33.8%, and 6.9%, respectively. Transarterial therapy (41.7%) was the most commonly performed initial treatment, followed by best supportive care (21.7%), surgical resection (16.7%), and local ablation therapies (10.6%). The overall rate of adherence to the BCLC treatment guideline was only 37.7%. The 1-, 3-, and 5-year OS rates were 65.6%, 46.2%, and 36.8%, respectively. @*Conclusions@#Between 2008 and 2011, approximately half of patients with HCC (48.3%) were candidates for curative treatment (BCLC stage 0 or A), but one-third of patients (33.8%) had advanced HCC (BCLC stage C). Transarterial therapy was the most commonly conducted initial treatment and the 5-year OS rate was 36.8% in this period.
ABSTRACT
The diagnosis of hepatocellular carcinoma (HCC) is based on imaging studies particularly in high-risk patients without histologic confirmation. This study evaluated the prevalence and characteristics of false-positively diagnosed HCC in a liver resection cohort for HCC. A retrospective review was performed of 837 liver resection cases for clinically diagnosed HCC between 2005 and 2010 at our institute. High-risk patients with tumors > 1 cm with one or two image findings consistent with HCC and tumors 0.05) compared to non-HCC patients except for higher rate of history of alcoholism (P < 0.05) observed in non-HCC patients. Four of 18 non-HCC patients (22.2%) showed diagnostic discordance on the dynamic imaging study. Despite the recent progression in diagnostic imaging techniques, 2.2% of cases were false-positively diagnosed as HCC in a liver resection patient cohort; and the final diagnosis was benign disease in 0.8% of liver resection patients clinically diagnosed with HCC.

We estimated the effect of various immunosuppressants (ISs) and metformin (M) to provide theoretical background of optimal therapeutic strategy for de novo colon cancer after liver transplantation (LT). Three colon cancer cell lines (HT29, SW620, and HCT116) were used in in vitro studies. HT29 was also used in BALB/c-nude mice animal models. Following groups were used in both in vitro and in vivo studies: sirolimus (S), tacrolimus (T), cyclosporin A (CsA), M, metformin/sirolimus (Met/S), metformin/tacrolimus (Met/T), and metformin/cyclosporin A (Met/CsA). 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed and western blot analyses were performed for mTOR pathway proteins, apoptosis proteins, and epithelial-mesenchymal-transition (EMT) proteins. Tumor volume was measured for 4 weeks after inoculation. MTT-assay revealed significant cell viability inhibition in all 3 colon cancer cell lines in groups of S, M, and Met/S. Of note, group Met/S showed synergistic effect compare to M or S group. Western blot analysis showed significant low levels of all investigated proteins in groups of S and Met/S in both in vitro and in vivo experiment. Tumor growth was significantly inhibited only in the Met/S group. Combination of Met and S showed the most potent inhibition in all colon cancer cell lines. This finding might have application for de novo colon cancer.

Few studies have compared outcomes in patients undergoing liver transplantation (LT) for hepatitis B virus (HBV) and alcoholic liver disease (ALD) in Asian countries in which living donor LT (LDLT) is dominant, where HBV is endemic and where there are no strict regulations on pre-transplant abstinence for ALD. This study compared post-LT outcomes of deceased donor LT (DDLT) in patients with ALD and HBV. Data from 220 patients who underwent primary DDLT at Seoul National University Hospital from January 2010 to December 2014, including 107 with HBV and 38 with ALD, were retrospectively analyzed. Seventy-four patients (69.2%) in the HBV group and 30 (78.9%) in the ALD group had United Network for Organ Sharing (UNOS) status 2A (P = 0.250). There were no significant differences in their 1-year (90.7% vs. 92.1%) and 3-year (82.1% vs. 82.3%) overall survival rates (P = 1.000). Multivariate analysis showed that high serum gamma glutamyltransferase concentration (≥ 70 IU/L) was independently prognostic of 1-year post-LT overall survival. Survival outcomes following DDLT were similar in Korean patients with ALD and HBV, even in the absence of strict pre-transplant abstinence from alcohol as a selection criterion.

PURPOSE: Liver volumetry is a vital component in living donor liver transplantation to determine an adequate graft volume that meets the metabolic demands of the recipient and at the same time ensures donor safety. Most institutions use preoperative contrast-enhanced CT image-based software programs to estimate graft volume. The objective of this study was to evaluate the accuracy of 2 liver volumetry programs (Rapidia vs. Dr. Liver) in preoperative right liver graft estimation compared with real graft weight. METHODS: Data from 215 consecutive right lobe living donors between October 2013 and August 2015 were retrospectively reviewed. One hundred seven patients were enrolled in Rapidia group and 108 patients were included in the Dr. Liver group. Estimated graft volumes generated by both software programs were compared with real graft weight measured during surgery, and further classified into minimal difference (≤15%) and big difference (>15%). Correlation coefficients and degree of difference were determined. Linear regressions were calculated and results depicted as scatterplots. RESULTS: Minimal difference was observed in 69.4% of cases from Dr. Liver group and big difference was seen in 44.9% of cases from Rapidia group (P = 0.035). Linear regression analysis showed positive correlation in both groups (P < 0.01). However, the correlation coefficient was better for the Dr. Liver group (R² = 0.719), than for the Rapidia group (R² = 0.688). CONCLUSION: Dr. Liver can accurately predict right liver graft size better and faster than Rapidia, and can facilitate preoperative planning in living donor liver transplantation.

BACKGROUNDS/AIMS: Fatigue is common in chronic hepatitis and end-stage liver disease. However, little is known about fatigue after liver transplantation (LT). We therefore evaluated the prevalence, severity, and related factors of fatigue after LT. METHODS: We retrospectively reviewed adult recipients who responded to our survey at outpatient clinics between April and May 2013. Fatigue and its severity were assessed using a questionnaire with the Fatigue Severity Scale (FSS). We defined fatigue as FSS of 4.0 or more and severe fatigue as FSS of 5.1 or more. The related factors including hepatocellular carcinoma and complications were analyzed. RESULTS: A total of 93 patients were included in this study. The mean age was 54.9 (19-76) years and two-thirds were men (67.7%). Living donor LT was 77.4%. Hepatitis B related liver disease was the main underlying disease (77.4%), with hepatocellular carcinoma accompanied in 33.3%. The mean follow-up period was 66.8+/-43.2 (2-171) months. The mean FFS was 2.83+/-1.48 (1.0-6.7) overall and 5.10+/-0.82 (4.0-6.7) in the fatigue group. Of the 93 adult patients, fatigue was presented in 20 patients (21.5%). Among these, 9 patients (45.0%) showed severe fatigue. Even though post-LT complications tended to be greater in the fatigue group (50.0% vs. 30.1% in the non-fatigue group, p=0.098), there were no significant related factors of fatigue after LT, including hepatocellular carcinoma and major complication. CONCLUSIONS: Fatigue is present in a considerable portion of recipients after LT, and almost half of them have severe fatigue. Further efforts are needed to decrease fatigue in LT recipients.

The aim of this study was to compare the clinical outcome and cost-effectiveness of preoperative biliary drainage (BD) methods in periampullary cancer, and to suggest guidelines for selecting the appropriate preoperative BD method. Between October 2004 and August 2010, 211 patients underwent pancreatoduodenectomy after preoperative BD. Clinical outcome and cost-effectiveness of the preoperative BD methods were compared based on the final drainage method used and on intention-to-treat analysis. There was no significant difference in drainage duration between percutaneous transhepatic biliary drainage (PTBD) and endoscopic BD groups (14.2 vs 16.6 days, respectively; P = 0.121) but daily diminution of serum bilirubin level was higher in the PTBD group (0.7 vs 0.6 mg/dL/day, respectively; P = 0.041). Based on intention-to-treat analysis, drainage duration was shorter (13.2 vs 16.5 days, respectively; P = 0.049), daily diminution of serum bilirubin level was higher (0.7 vs 0.6 mg/dL/day, respectively; P = 0.041). Medical care cost was lower (14.2 vs 15.7 x 10(3) USD, respectively; P = 0.040) in the PTBD group than in the endoscopic BD group. When selecting the preoperative BD method, practitioners should consider that PTBD is more cost-effective and safer than endoscopic BD.

PURPOSE: Laparoscopic continuous ambulatory peritoneal dialysis (CAPD) catheter insertion is used instead of open CAPD insertion because additional measures to prevent complications can be made without a conventional laparotomy. This study compared the early experience of laparoscopic CAPD catheter insertion with open CAPD insertion in children. METHODS: Between January 2006 and May 2011, 52, 16 and 36 patients who underwent CAPD insertion, laparoscopic CAPD insertion and open CAPD insertion, respectively, for end stage renal disease at Seoul National University Children's Hospital were enrolled in this study. The clinicopathological factors, operative factors and outcomes were analyzed by a retrospective medical record review. RESULTS: The mean operative time of the laparoscopic group was longer than that of the open groups (78 minutes vs 60 minutesm, p value=0.079). In the laparoscopic group, 3 patients underwent closure of the processus vaginalis and the occurrence of an inguinal hernia was prevented, whereas 3 patients in the open group underwent herniorrhaphy for an inguinal hernia. The mean period of catheter use in the laparoscopic and open group was 201 and 984 days, respectively. Complications occurred more frequently in the open group than in the laparoscopic group (14 patients (38.9%) vs. 2 patients (12.5%), p value=0.059). Peritonitis (19.4%) was the most common complication, which occurred only in the open group, followed by catheter obstruction due to omental wrapping. Catheter migration occurred more frequently in the open group (20%) than the laparoscopic group (12.5%). CONCLUSION: These results suggest that laparoscopic CAPD catheter insertion can be a suitable method for CAPD catheter insertion in children.
