ABSTRACT

DNP (2,4-dinitrophenol) has been commonly used as a weight loss aid; in particular, it has been used by body builders to achieve significant fat loss while maintaining muscle mass. The sale of DNP was banned due to some cases of fatal poisoning. We describe an autopsy case of a 39-year-old man who died from taking DNP to treat obesity. He was 183 cm tall and weighed 101 kg (body mass index of 31). External examination did not reveal any specific findings implicating the cause of death. Gross examination revealed that the heart weight was 450 g, and there were no significant findings in the coronary arteries and myocardium, except for a few petechiae of the epicardium. The DNP concentration in the subject’s blood was 38.28 mg/L. According to references, a DNP blood concentration of 28 mg/L or higher would result in death. Therefore, the cause of death in this autopsy case was DNP toxicity.

ABSTRACT

Purpose@#This study aimed to identify the effect of self-esteem and spouse support on prenatal depression. @*Methods@#The subjects were 131 pregnant women who visited two women clinics located in Changwon City. Data were collected from September 25 to November 20, 2019, and the self-report questionnaire included spouse support, self-esteem, and prenatal depression. The collected data were analyzed by IBM SPSS Statistics ver. 23.0 using descriptive statistics, independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis. @*Results@#Prenatal depression had a significant negative correlation with self-esteem (r=-0.39, p=0.001) and spouse support (r=-0.36, p<0.001). The factors affecting prenatal depression were religion (β=-0.16, p=0.035), monthly family income (β=-0.15, p=0.040), self-esteem (β=-0.25, p=0.002), and spouse support (β=-0.19, p=0.017); these variables explained 28.4% of the variance in prenatal depression. @*Conclusion@#To prevent depression in pregnant women, professional counseling and support systems such as spouses, religious and social environments should be applied to pregnant women, especially those with low self-esteem. Additionally, more financial support should be provided for low-income pregnant women. Further, there is a need to screen and manage the risk of depression in pregnancy.

ABSTRACT

PURPOSE: Treatment targeting immune checkpoint with programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors has demonstrated efficacy and tolerability in the treatment of metastatic urothelial carcinoma (mUC). We investigated the efficacy and safety of atezolizumab in mUC patients who failed platinum-based chemotherapy. MATERIALS AND METHODS: A retrospective study using the Samsung Medical Center cancer chemotherapy registry was performed on 50 consecutive patients with mUC treated with atezolizumab, regardless of their PD-L1(SP142) status, as salvage therapy after chemotherapy failure between May 2017 and June 2018. Endpoints included overall response rate (RR), progression-free survival (PFS), and safety. RESULTS: Among 50 patients, men constituted 76% and the median age was 68 years (range, 46 to 82 years). Twenty-three patients (46%) received atezolizumab as second-line therapy. PD-L1 (SP142) status IC0/1 and IC2/3 were found in 21 (42%) and 21 (42%) of patients, respectively; in eight patients (16%), PD-L1 (SP142) expression was not available. Atezolizumab was generally well tolerated, with pruritus and fatigue being the most commonly observed toxicities. As a result, partial response was noted in 20 patients (40%), with 12 (24%) stable diseases. RRwas higherin IC2/3 (62%) than in IC0/1 patients (24%, p=0.013). The median PFS was 7.4 months (95% confidence interval, 3.4 to 11.4 months). As expected, PFS also was significantly longer in IC2/3 patients than in IC0/1 (median, 12.7 vs. 2.1 months; p=0.005). PFS was not significantly influenced by age, sex, performance status, number of previous chemotherapy, site of metastases, or any of the baseline laboratory parameters. CONCLUSION: In this retrospective study, atezolizumab demonstrated clinically efficacy and tolerability in unselected mUC patients who failed platinum-based chemotherapy.

ABSTRACT

PURPOSE: The purpose of this study was to compare prognostic differentiation performances of the 7th and the 8th edition of American Joint Committee on Cancer (AJCC) staging system for gastric cancer (GC) patients. MATERIALS AND METHODS: A total of 1,633 GC patients who underwent curative D2 resection followed by adjuvant chemotherapy alone (CA) or concurrent chemo-radiotherapy (CCRT) from 2004 to 2013 were included. Concordance index (c-index) was applied to compare the discriminatory ability. RESULTS: In the 8th edition, migration of stage was detected in 248 patients (15.2%). Among them, 121 patients were up-staged while 127 patients were down-staged. Overall, there was no statistically significant difference in the discriminatory ability between the 7th and 8th editions. The new edition of staging system, however, showed a trend of better prognostic performance not only in recurrence-free survival (c-index=0.734; 95% confidence interval [CI], 0.706 to 0.762 in the 7th edition vs. c-index=0.740; 95% CI, 0.712 to 0.768 in the 8th edition; p=0.14), but also in overall survival (c-index=0.717; 95% CI, 0.688 to 0.745 in the 7th edition vs. c-index=0.722; 95% CI, 0.694 to 0.751 in the 8th edition; p=0.19), especially in stage III. This finding was repeated in the subgroup analysis regardless of adjuvant CA or CCRT. CONCLUSION: Generally, the 8th edition of AJCC staging system had failed to show a superior discriminatory ability for curatively D2 resected GC patients than the 7th edition, although there was a trend of better prognostic performance of the new edition, regardless of adjuvant treatment method.

ABSTRACT

PURPOSE: The optimal cytotoxic regimens have not been established for patients with non-small cell lung cancer (NSCLC) who develop disease progression on first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI). MATERIALS AND METHODS: We conducted a multi-center randomized phase II trial to compare the clinical outcomes between pemetrexed plus cisplatin combination therapy followed by maintenance pemetrexed (PC) and pemetrexed monotherapy (P) after failure of first-line EGFR-TKI. The primary objective was progression-free survival (PFS), and secondary objectives included overall response rate (ORR), overall survival (OS), health-related quality of life (HRQOL), and safety and toxicity profiles. RESULTS: A total of 96 patientswere randomized, and 91 patientswere treated at 14 centers in Korea. The ORR was 34.8% (16/46) for the PC arm and 17.8% (8/45) for the P arm (p=0.066). With 23.4 months of follow-up, the median PFS was 5.4 months in the PC arm and 6.4 months in the P arm (p=0.114). The median OS was 17.9 months and 15.7 months in PC and P arms, respectively (p=0.787). Adverse events ≥ grade 3 were reported in 12 patients (26.1%) in the PC arm and nine patients (20.0%) in the P arm (p=0.491). The overall time trends of HRQOL were not significantly different between the two arms. CONCLUSION: The outcomes of pemetrexed therapy in NSCLC patients with disease progression after firstline EGFR-TKI might not be improved by adding cisplatin.

ABSTRACT

PURPOSE: Allergic diseases have been increasing worldwide over the past few decades. Allergic sensitization is a pivotal risk factor for the development of allergic diseases. The purpose of this study was to examine changes in allergic sensitization patterns of aeroallergens over the last 10 years in children with respiratory allergic diseases. METHODS: We retrospectively reviewed the medical records of 12,848 children under the age of 18 years who received skin prick tests (n=3,852) or serum specific IgE tests (n=8,996) to evaluate sensitization from 2007 to 2016 in a single center, Seoul, Korea. RESULTS: Sensitization rate to house dust mite (Dermatophagoides farinae and Dermatophagoides pteronyssinus) reached a plateau in preschool (28.3%–32.8%) and schoolchildren (45.8%–47.2%). Sensitization rate to animal dander (cat and dog) was increasing from 8.4% to 12.5% in preschool children and from 10.3% to 18.6% in schoolchildren (trend P<0.001 each). In preschool children, tree (birch, oak, and alder; from 3.5% to 6.4%), grass (timothy; from 0.8% to 6.5%), weed (ragweed and mugwort; from 2.8% to 6.9%) pollens and mold (Alternaria; from 2.5% to 6.0%) were also in similar increasing pattern (trend P=0.001, P<0.001, P=0.003, and P<0.001, respectively). Additionally, tree (from 9.0% to 15.2%), grass (from 2.6% to 5.2%) pollens were also in increasing pattern in schoolchildren (trend P<0.001 and P=0.024, respectively). CONCLUSION: Over the past 10 years, sensitization patterns of aeroallergen have been changing in Korean children with allergic diseases. We should pay attention to the changing patterns of allergic sensitization to educate and prevent the allergic disease.

ABSTRACT

PURPOSE: The purpose of this study was to determine the mediating effects of self-efficacy and the belief about medication on the association between depression and medication adherence in patients with systemic lupus erythematosus. METHODS: 128 patients aged ≥19 years, who were regular outpatients or admitted patients diagnosed with systemic lupus erythematosus at a tertiary hospital in B city, participated in this study. Data were collected by using a self-administered questionnaire. Testing of mediating effects was analyzed by a parallel redundant mediated model using the PROCESS macro for SPSS version 3.3. RESULTS: They scored an average of 16.71±11.13 for depression, 694.14±170.68 for self-efficacy, 3.05±4.60 for the belief about medication, and 90.14±15.37 for medication adherence. The direct effect of depression on medication adherence was not statistically significant, but the indirect effects of depression mediated with self-efficacy and belief about medication were statistically significant. CONCLUSION: It is necessary to develop and apply a nursing intervention program that can not only relieve depression but also promote self-efficacy and the belief about medication with the objective of improving medication adherence among patients with systemic lupus erythematosus.

ABSTRACT

PURPOSE: The purpose of this study was to examine the correlation between a flexible parental visiting environment and parental stress in neonatal intensive care units (NICUs).METHODS: The study participants included 60 parents of premature infants in NICUs. Structured questionnaires and interviews, as well as observations by researchers using a caregiving behavior checklist, were used to measure the flexibility of the parental visiting environment and parents' stress levels. Quantitative and qualitative data were collected concurrently and were initially analyzed as separate data sets. Data collection extended from March 11, 2018 to June 30. 2018 and the data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, and Pearson correlation coefficients.RESULTS: There was a negative correlation (r=−.30, p=.021) between parental stress and the total number of visits in 7 days. We also found that the average duration of each visit and the number of caregiving behaviors performed by parents were positively correlated (r=.73, p<.001).CONCLUSION: When designing a flexible visiting environment for parents, parents should be encouraged to visit their babies. By doing so, stress can be reduced both for babies and for parents. Therefore, it is suggested that the related polices and regulations in South Korea should be changed to provide more a flexible visiting environment to promote better parent-child attachment and family adjustment.

ABSTRACT

BACKGROUND/AIMS: Infections following liver transplant (LT) remain a major cause of mortality. This study was conducted to evaluate risk factors for infection and to review clinical characteristics. METHODS: Medical records of patients who underwent LT from 2010 to 2014 were retrospectively analyzed. Binary logistic regression analysis was used to investigate risk factors of infection. Kaplan-Meier analysis was used to predict prognosis of infected and non-infected groups. RESULTS: Of 185 recipients, 89 patients experienced infectious complications. The median follow-up period was 911 days (range, 9 to 2,031). The infected group had higher 1-year mortality (n = 22 [24.7%] vs. n = 8, [8.3%], p = 0.002), and longer postoperative admission days (mean: 53.7 ± 35.8 days vs. 28.3 ± 13.0 days, p < 0.001), compared to the non-infected group. High preoperative Model for End-Stage Liver Disease (MELD) score (odds ratio [OR], 1.057; 95% confidence interval [CI], 1.010 to 1.105; p = 0.016), deceased-donor type (OR, 5.475; 95% CI, 2.442 to 12.279; p < 0.001), and acute rejection (OR, 3.042; 95% CI, 1.241 to 7.454; p = 0.015) were independent risk factors associated with infection. Intra-abdominal infection (n = 35, 20.8%) was the major infectious complication. Among identified bacteria, Enterococcus species (28.4%) were major pathogens, followed by Escherichia coli and Klebsiella species. CONCLUSIONS: High preoperative MELD score, deceased-donor type, and acute rejection were risk factors associated with infection. To prevent infections following surgery, it is important to determine the appropriate time of operation before the recipient has a high MELD score.

ABSTRACT

PURPOSE: Little is known about the clinical value of peripheral blood immune profiling. Here, we aimed to identify colorectal cancer (CRC)-related peripheral blood immune cells and develop liquid biopsy-based immune profiling models for CRC diagnosis. METHODS: Peripheral blood from 131 preoperative patients with CRC and 174 healthy controls was analyzed by flow cytometry and automated hematology. CRC-related immune factors were identified by comparing the mean values of immune cell percentages and counts. Subsequently, CRC diagnostic algorithms were constructed using binary logistic regression. RESULTS: Significant differences were observed in percentages and counts of white blood cells, lymphocytes, neutrophils, regulatory T cells, and myeloid-derived suppressor cells (MDSCs) of patients and controls. The neutrophil/lymphocyte and Th1/Th2 ratios were also significantly different. Likewise, the percentages and counts of peripheral blood programed death 1, cytotoxic T lymphocyte antigen 4, B-and T-lymphocyte attenuator, and lymphocyte activation gene-3 were higher in patients with CRC. The binary logistic regression model included 12 variables, age, CD3+%, NK%, CD4+CD279+%, CD4+CD25+%, CD4+CD152+%, CD3+CD366+%, CD3+CD272+%, CD3+CD223+%, CD158b−CD314+CD3−CD56+%, Th2%, and MDSCs cells/µL, for the prediction of cancer. Results of retrospective and prospective evaluation of the area under the curve, sensitivity, and specificity were 0.980 and 0.940, 91.53% and 85.80%, and 93.50% and 86.20%, respectively. CONCLUSION: Peripheral blood immune profiling may be valuable in evaluating the immunity of CRC patients. Our liquid biopsy-based immune diagnostic method and its algorithms may serve as a novel tool for CRC diagnosis. Future largescale studies are needed for better characterization of its diagnostic value and potential for clinical application.

ABSTRACT

PURPOSE: The optimal treatment strategy for patients with metastatic non-clear cell type renal cell carcinoma (nccRCC) remains unclear. Although several inhibitors of vascular endothelial growth factor have recently shown efficacy against nccRCC, the clinical benefit of pazopanib in nccRCC has not been analyzed. We therefore designed a single-arm, open-label, phase II study to determine the efficacy and safety of pazopanib in patients with nccRCC. MATERIALS AND METHODS: Patients with locally advanced or metastatic nccRCC, exceptfor collecting duct or sarcomatoid type, received 800 mg/day of pazopanib daily until progression of disease or intolerable toxicity. One cyclewas defined as 4 weeks and tumor response was evaluated every two cycles. The primary objective was overall response rate (ORR). RESULTS: A total of 29 eligible patients were enrolled at nine centers in Korea from December 2012 and September 2014. The median age of the patients was 58 years (range, 27 to 76 years) and 21 patients (72%) were male. Regarding histology type, 19 patients had papillary, three had chromophobe, two had unclassified and five had unknown non-clear cell type. Of 28 evaluable patients, eight achieved a confirmed partial response with ORR of 28%. The median progression-free survival was 16.5 months (95% confidence interval, 10.9 to 22.1) and median overall survival was not reached. Sixteen patients (55%) experienced treatment-related toxicity of grade 3 or more, but most adverse events were overcome through dose reduction and delay. CONCLUSION: In this prospective phase II study, pazopanib demonstrated promising activity and tolerable safety profile in patients with metastatic nccRCC.

ABSTRACT

PURPOSE: We aimed to discuss the roles of radiation and chemotherapy as adjuvant treatment in patients with staged IB GC who were enrolled in the adjuvant chemoradiotherapy in stomach tumors (ARTIST) trial. MATERIALS AND METHODS: Among the 458 patients who were enrolled in the ARTIST trial, 99 had stage IB disease. The patients were randomly assigned to receive either adjuvant chemoradiotherapy with capecitabine plus cisplatin (XP, n=50) or chemoradiotherapy (XPRT, n=49). Survival analyses were performed in accordance with the AJCC 2010 staging system. RESULTS: According to the AJCC 2010 system, stage migration from IB to II occurred in 71% of the patients; 98% of the T2 N0 cases were reclassified as T3 N0, and 42% of the T1 N1 cases were reclassified as T1 N2. When comparing survival outcomes between the XPRT and XP arms for stage IB cancer (AJCC 2002), no significant difference in 5-year disease-free survival (DFS) between the 2 arms was found. (median 5-year DFS, not reached, P=0.256). The patients classified as having stage IB cancer (AJCC 2002) and reclassified as having stage II cancer (AJCC 2010) exhibited worse prognoses than those who remained in stage IB, although the difference was not statistically significant (5-year DFS rate, 83% vs. 93%). When we compared 5-year DFS in 70 patients with stage II (AJCC 2010), the addition of radiotherapy to XP chemotherapy did not show better outcome than XP alone (P=0.137). CONCLUSIONS: The role of adjuvant chemoradiotherapy in the treatment of stage IB GC (AJCC 2002) warrants further investigation.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the severity of disease in children with acute bronchiolitis according to the type of infected virus. METHODS: From November 2007 to May 2015, 768 patients under 2 years of age who underwent real time-polymerase chain reaction of nasopharyngeal aspirates admitted to the Department of Pediatrics of Dongguk University Ilsan Hospital for acute bronchiolitis were enrolled. Severe bronchiolitis was defined as presence of one or more kinds among tachypnea, chest retraction, needs of O2 inhalation or ventilator care. RESULTS: The severity of bronchiolitis was increased with shorter fever duration (P < 0.001) and previous wheezing episodes (P = 0.005). In the case of single infection, respiratory syncytial virus (RSV) A only increased the severity of acute bronchiolitis (P = 0.012). However, the severity of illness decreased when RSV A coinfected with adenovirus (P = 0.034), human rhinovirus (P = 0.038), or human coronavirus NL63 (P = 0.042). On the other hand, when human rhinovirus was coinfected with enterovirus (P = 0.013) or parainfluenza 3 (P = 0.019), the severity was increased. When human metapneumovirus coinfected with human bocavirus, the severity was increased (P = 0.038). CONCLUSION: Acute bronchiolitis was associated with increased severity only when RSV A infected solely, but several viruses increased or decreased the severity when coinfection occurred. Therefore, it may be helpful in predicting the course of the acute bronchiolitis according to the affected virus.

ABSTRACT

This study was to investigate the effect of subcutaneous injection of the adipose stem cells (ASCs) with conditioned media (CM) in the treatment of acne vulgaris scar. We used Adult male New Zealand white rabbit ears as an animal model and induced acne formation by Kignman method. Adipose tissue was isolated and harvested from the scapula of rabbits, and ASCs were cultured and expanded until passage 1. There have four groups in our experiment, include phosphate buffered saline (PBS), ASCs with PBS (ASC + PBS), CM, and ASCs with CM (ASC + CM) group. This solution of 0.6 ml injected to subcutaneous in each group. ASC + PBS and ASC + CM groups were containing ASCs of 5.0 × 106 cells/ml. We analyzed the treatment of 4 groups to scar tissue after 2 and 4 weeks by hematoxylin and eosin stain, immunohistochemistry, and RNA expression level of tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α), and matrix metalloproteinase-2 (MMP-2). Also, the expression of keratin 16 (K16) was detected by western blot analysis. H&E stain showed that infiltration of inflammation cells was significantly reduced at 2 and 4 weeks, as well as re-epithelialization was improved in the ASC + CM group. The ASC + CM gourp was reduced both expression levels of TNF-α, IL-1α, and MMP-2 and K16 protein level. In conclusion, the ASCs with CM has a significant curative effect on acne vulgaris scar, more to the point, the CM has a key role on treatment. It could be applied to a therapeutic approach to regenerate to treat acne vulgaris scar.

ABSTRACT

PURPOSE: The purpose of this study was to examine the possible direction of critical care nursing research in the future by analyzing the trends of recent Korean studies.METHOD: Using a database search, we selected 263 articles on critical care nursing that were published in Korean journals between 2008 and 2017. Then, we conducted an integrative review of the contents of the selected articles and analyzed the English abstracts using the relevant packages and functions of the R program.RESULTS: The number of studies concerning critical care nursing has increased over the 10-year period, and the specific topic of each study has diversified according to the time at which it was conducted. In terms of quality, the majority of the research was published in high-level academic journals. The key words regularly studied over the past decade were: knowledge, delirium, education, restraint, stress, and infection. Studies related to vancomycin-resistant enterococci infection, compliance, and standards have decreased, while studies related to death, communication, and safety have increased.CONCLUSION: Randomized controlled trials and protocol research for evidence-based critical care need to be conducted, as does research on family involvement. The key word analysis of unstructured text used in this study is a relatively new method; it is suggested that this method be applied to various critical care nursing research and develop it methodologically.

ABSTRACT

PURPOSE: Distribution and survival of sarcoma in Korea are not well described, after the changing of sarcoma classification on 2013. The researchers investigated the distribution and survival in single center 2017 cases of sarcoma.METHODS: Patients with primary sarcoma, who underwent surgery, were investigated. All cases were collected during a 20 year period (1995–2015) from Samsung Medical Center in Korea. Histopathologic types were classified by World Health Organization (WHO) classification (2013). And overall survival rates were analyzed.RESULTS: Between 1995 and 2015, 2017 patients were collected. The most frequent type of sarcoma was gastrointestinal tumor (15%), followed by liposarcoma (12%), leiomyosarcoma (9%), dermatofibrosarcoma (6%), giant cell sarcoma (6%). The most common primary site of sarcoma was the intra-abdominal area (45%, including visceral area). Extremities accounted for 26% of all cases. Sixteen percent of sarcoma were located in retroperitoneal area. The overall survival rate was 70.4% (median follow-up time, 36.8 months; range, 0.1–261.3 months). The best prognosis was dermatofibrosarcoma (100%, 5-year survival rate). The worst prognosis was angiosarcoma (39.3%). Survival analysis by the primary site demonstrated favor prognosis in extremities than head & neck, chest lesion.CONCLUSION: The researchers reported Korean sarcoma characteristics with using the new WHO classification.

ABSTRACT

In keloids, the mechanism underlying the excessive accumulation of extracellular matrix after injury of the skin is unclear, and there is no effective treatment because of the incomplete understanding of their pathogenesis; thus, a high recurrence rate is observed. We studied a new marker of keloids to determine a new treatment strategy. First, the keloid gene expression profile (GSE44270) was analyzed (downloaded from the Gene Expression Omnibus database) and the new keloid marker candidate, epidermal growth factor (EGF)-like repeats and discoidin I-like domains 3 (EDIL3) which were upregulated in keloid samples was identified. Knockdown of EDIL3 is known to suppresses angiogenesis by downregulating relevant inhibitory factors that can limit the supply of survival factors to tumor cells from the circulation via the vascular endothelial cells. In keloids, the mechanism of action of EDIL3 may be similar to that in tumors; the inhibition of apoptosis in tumor cells via a reduction in the apoptosis of blood vessels by upregulating an angiogenic factor. To determine whether EDIL3 is involved in keloid formation, we performed knockdown of EDIL3 in keloid fibroblasts in vitro by transfection with anti-EDIL3 small interfering RNA (via microporation). EDIL3 was upregulated in keloid fibroblasts compared with normal fibroblasts in collagen type I, II and III. Our results indicate the control of EDIL3 expression may be a new promising treatment of keloid disease also the molecular targeting of EDIL3 may improve the quality of treatment and reduce the formation of keloids.

ABSTRACT

Transplantation studies about the clinical differences according to the type of donors are mostly conducted in western countries with rare reports from Asians. The aims of this study were to evaluate the clinical impacts of the type of donor, and the predictors of 1-year mortality in patients who underwent liver transplantation (LT). This study was performed for liver transplant recipients between May 2010 and December 2014 at the Pusan National University Yangsan Hospital. A total of 185 recipients who underwent LT were analyzed. Of the 185 recipients, 109 (58.9%) belonged to the living donor liver transplantation (LDLT) group. The median age was 52.4 years. LDLT recipients had lower model for end-stage liver disease (MELD) score compared with better liver function than deceased donor liver transplantation (DDLT) recipients (mean ± standard deviation [SD], 12.5 ± 8.3 vs. 24.9 ± 11.7, respectively; P < 0.001), and had more advanced hepatocellular carcinoma (HCC) (62.4% vs. 21.1%, respectively; P = 0.001). In complications and clinical outcomes, LDLT recipients showed shorter stay in intensive care unit (ICU) (mean ± SD, 10.8 ± 8.8 vs. 23.0 ± 13.8 days, respectively, P < 0.001), ventilator care days, and post-operative admission days, and lower 1-year mortality (11% vs. 27.6%, respectively, P = 0.004). Bleeding and infectious complications were less in LDLT recipients. Recipients with DDLT (P = 0.004) showed higher mortality in univariate analysis, and multi-logistic regression analysis found higher MELD score and higher pre-operative serum brain natriuretic peptide (BNP) were associated with 1-year mortality. This study may guide improved management before and after LT from donor selection to post-operation follow up.

ABSTRACT

PURPOSE: The aim of this study was to confirm the efficacy and safety of regorafenib for advanced gastrointestinal stromal tumors (GISTs) reported in the GRID phase III trial in Korean patients. MATERIALS AND METHODS: Fifty-seven Korean patientswith advanced GISTwho experienced both imatinib and sunitinib failure were enrolled in the management access program between December 2012 and November 2013 and treated with regorafenib (160 mg orally once daily in a 3 weeks on/1 week off). RESULTS: None of the patients achieved a complete or partial response while 25 patients (44%) showed stable disease for ≥ 12 weeks. With a median follow-up of 12.7 months (range, 0.2 to 27.6 months), the median progression-free survival and overall survival were 4.5 months (95% confidence interval [CI], 3.8 to 5.3) and 12.9 months (95% CI, 8.1 to 17.7), respectively. Interestingly, 15 patients (26%) experienced an exacerbation of their cancer-related symptoms (abdominal pain in eight and abdominal distension in five) during the rest period for regorafenib, but all were ameliorated upon the resumption of regorafenib. The most common grade 3 or 4 adverse event was a hand-foot skin reaction (25%). The regorafenib dose was reduced in 44 patients (77%) due to toxicity, which manifested mainly as a hand-foot skin reaction (n=31). CONCLUSION: This study confirmed the efficacy and safety of regorafenib for advanced GIST after imatinib and sunitinib failure in Korean patients. Considering the exacerbation of the cancer-related symptoms observed during the rest periods, further exploration of the continuous dosing schedule of regorafenib is warranted in future clinical trials.
