RESUMEN
BACKGROUND: The connection between renal dysfunction and cardiovascular dysfunction has been consistently shown. In patients with liver cirrhosis, renal dysfunction shows a tight correlation with prognosis after liver transplantation (LT); therefore, precise renal assessment is mandatory. Cystatin C, a sensitive biomarker for assessing renal function, has shown superiority in detecting mild renal dysfunction compared to classical biomarker creatinine. In this study, we aimed to compare cystatin C and creatinine in predicting 30-day major cardiovascular events (MACE) and all-cause mortality in LT recipients with normal serum creatinine levels. PATIENTS AND METHODS: Between May 2010 and October 2015, 1181 LT recipients (mean Model for End-stage Liver Disease score 12.1) with pretransplantation creatinine level ≤1.4 mg/dL were divided into tertiles according to each renal biomarker. The 30-day MACE was a composite of troponin I >0.2 ng/mL, arrhythmia, congestive heart failure, death, and cerebrovascular events. RESULTS: The highest tertile of cystatin C (≥0.95 mg/L) was associated with a higher risk for a 30-day MACE event (odds ratio: 1.62; 95% confidence interval: 1.07 to 2.48) and higher risk of death (hazard ratio: 1.96; 95% confidence interval: 1.04 to 3.67) than the lowest tertile (<0.74 mg/L) after multivariate adjustments. However, the highest tertile of creatinine level showed neither increasing MACE event rate nor worse survival rate compared with the lowest tertile (both insignificant after multivariate adjustment). CONCLUSIONS: Pretransplantation cystatin C is superior in risk prediction of MACE and all-cause mortality in LT recipients with normal creatinine, compared to creatinine. It would assist further risk stratification which may not be detected with creatinine.

BACKGROUND: Many studies have reported the negative influence of diabetes and hypertension on morbidity and mortality in the general population. In liver transplantation (LT) recipients, prevalence of nonalcoholic fatty liver disease and metabolic syndrome is increasing. Hence, concerns over the negative influence of metabolic syndrome, including diabetes and hypertension, are growing. However, there have been few studies about the outcomes of LT recipients with diabetes with/without hypertension. We aimed to evaluate the impact of diabetes with/without hypertension on the outcomes of LT. METHODS: Between May 2010 and October 2015, 814 LT recipients (median age, 51 [46-55] years; median MELD score, 13 [9-18]), without overt cardiovascular disease were retrospectively evaluated. To rigorously adjust for clinically confounding factors, a 1:2 propensity score matching analysis was performed. Kaplan-Meier survival curves and Cox proportional hazard regression analysis were performed to examine the association between diabetes with/without hypertension and all-cause mortality or graft survival rate. RESULTS: There were 77 (9.5%) graft failures and 71 (8.7%) deaths during a median follow-up of 2.4 years. After 1:2 matching of 173 (21.3%) diabetic patients, no significant differences were evident in graft survival rate (log-rank test, P = .46; and hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.55-2.06; P = .865) and all-cause mortality (log-rank test, P = .59; and HR, 1.06; 95% CI, 0.55-2.06; P = .727). Separate 1:2 matching was applied to a subgroup of 43 (5.3%) patients with diabetes and hypertension. This matching also showed no difference in graft survival rate (log-rank test, P = .45; and HR, 1.35; 95% CI, 0.43-4.27; P = .613) and all-cause mortality (log-rank test, P = .25; and HR, 1.87; 95% CI, 0.54-6.50; P = .325). CONCLUSION: Diabetes with/without hypertension does not have an impact on graft survival rate or all-cause mortality in LT recipients.

BACKGROUND: Antiphospholipid antibodies (aPL), including anticardiolipin (aCL), anti-ß2-glycoprotein I (anti-ß2GPI), and lupus anticoagulant (LA) antibodies, are frequently found in liver cirrhosis and associated with splanchnic vein thrombosis. Although the risk factors of early allograft dysfunction (EAD) are known, the association between EAD and aPL has been poorly investigated. We hypothesized that LA, potent aPL with thrombotic potential, may be associated with EAD development after living donor liver transplantation (LDLT). METHODS: Data of 719 patients who underwent LDLT from February 2014 to June 2016 at our center were retrospectively collected and analyzed. Patients were divided into 2 groups according to the positivity of LA screening test (LA group [n = 148] vs no-LA group [n = 571]). Risk factors for EAD were investigated using multivariable regression analysis and inverse probability of treatment weighting (IPTW) of propensity scores. RESULTS: The prevalence of LA screening positivity, confirmatory test positivity, and EAD was 20.6%, 1.1%, and 11.3%, respectively. aCL positivity rate was 7.5% and anti-ß2GPI positivity rate was 7.0%. The EAD prevalence in LA and no-LA group was 25.7% and 7.5%, respectively. However, multivariable and IPTW analyses showed no association between EAD and LA screening positivity (P = .263 and P = .825, respectively), although a significant association was found in univariate analysis (odds ratio, 4.242; P < .001). Model for End-stage Liver Disease score, operation time, and C-reactive protein level remained significant after multivariable analysis. CONCLUSION: A positive LA screening test result was associated with EAD only in the univariate analysis. Inflammation, based on C-reactive protein level, was more important for EAD development.

BACKGROUND: Conventional anorectal manometric parameters based on linear waves cannot properly predict balloon expulsion (BE) time. We aimed to determine the correlation between integrated pressurized volume (IPV) parameters during simulated evacuation (SE) and BE time in healthy individuals and constipated patients and to assess the correlation between each parameter and symptoms. METHODS: A total of 230 male participants (including 26 healthy volunteers and 204 chronically constipated patients) underwent high-resolution anorectal manometry (HRAM) and BE tests. The IPV was calculated by multiplying the amplitude, distance, and time from the HRAM profile. Receiver operating characteristic curve (ROC) analysis and partial least square regression (PLSR) were performed. KEY RESULTS: ROC analysis indicated that the IPV ratio between the upper 1 cm and lower 4 cm of the anal canal was more effective for predicting BE time (area under the curve [AUC]: 0.74, 95% confidence interval [CI]: 0.67-0.80, P < .01) than the conventional anorectal parameters, including defecation index and rectoanal gradient (AUC: 0.60, 95% CI: 0.52-0.67, P = .01). PLSR analysis of a linear combination of IPV parameters yielded an AUC of 0.79. Moreover, the IPV ratio showed a greater clinical correlation with patient symptoms than conventional parameters. CONCLUSIONS AND INFERENCES: The IPV parameters and the combination of IPV parameters via PLSR were more significantly correlated with BE time than the conventional parameters. Thus, this study presents a useful diagnostic tool for the evaluation of pathophysiologic abnormalities in dyssynergic defecation using IPV and BE time.

BACKGROUND: Measuring activated clotting time (ACT) is widely performed to monitor heparin therapy. Regardless of anticoagulant use, ACT is affected by coagulopathies such as coagulation factor deficiency and thrombocytopenia. However, its use in end-stage liver disease (ESLD) with complex coagulopathy is not well characterized. We evaluated whether ACT could be used to detect innate coagulopathy in ESLD patients. METHODS: We retrospectively assessed Hemochron (International Technidyne, Edison, NJ, USA) ACT (FTCA 510, normal range 105-167 seconds) and INTEM clotting time (CT) of rotational thromboelastometry (ROTEM; ROTEM delta, Pentapharm GmbH, Munich, Germany) (100-240 seconds) in 366 liver transplantation (LT) recipients, simultaneously measured before anesthetic induction for LT. Multiple linear regression analyses helped identify the factors related to ACT in ESLD patients. The relationship between ACT and INTEM CT was evaluated by Spearman rank correlation analysis and receiver operating characteristic curve. RESULTS: Median ACT was 143 seconds (range 73-295 seconds), and 60 patients (16.4%) had ACTs of >167 seconds. Multiple regression analyses revealed that prolonged prothrombin time, activated partial thromboplastin time, low antithrombin III, and young age were associated with high ACT levels. INTEM CT was associated with ACT independent of liver disease severity, while EXTEM CT was not. ACT was moderately correlated with INTEM CT (r = 0.535), and the optimal cutoff value of ACT for predicting INTEM CT >240 seconds was 151 seconds (area under the curve = 0.787). CONCLUSIONS: In ESLD patients, ACT is effective in detecting prolonged INTEM CT. Therefore, ACT may be used to predict intrinsic pathway defects with a cutoff value of 151 seconds, suggesting feasibility when ROTEM is unavailable.

BACKGROUND: The importance of heart rate (HR) measurement as a prognostic factor has been recognized in many clinical conditions, such as hypertension, coronary artery disease, or heart failure. Patients with liver cirrhosis tend to have increased resting HR as consequence of hyperdynamic circulation. In the current study, we examined whether pretransplant resting increased HR is associated with overall mortality in cirrhotic patients following liver transplantation (LT). PATIENTS AND METHODS: We retrospectively collected and analyzed the data of 881 liver recipients who underwent LT surgery between October 2009 and September 2012. Patients were categorized into 3 groups by tertile of resting HR as follows: tertile 1 group, HR ≤ 65 beats per minute (bpm); tertile 2 group, HR 66 to 80 bpm; and tertile 3 group, HR > 80 bpm. RESULTS: Kaplan-Meier analysis showed that the all-cause mortality rate was significantly different according to tertiles of HR (P = .016, log-rank test). The multivariate Cox regression analysis showed that tertile 3 group was significantly associated with higher risk for all-cause mortality (hazard ratio 1.83, 95% confidence interval, 1.10-3.07; P = .021) compared with tertile 1 group, after adjusting for clinically significant variables in univariate analysis. CONCLUSIONS: Our results demonstrate that pretransplant resting tachycardia can identify patients at high risk of death in cirrhotic patients following LT, suggesting that further study will be need to clarify relationship between HR burden and sympathetic cardiac neuropathy.

BACKGROUND: : In our preliminary study, the modified Marsh (M-Marsh) model caused an inadvertent underdosing of propofol in underweight patients. However, the predictive performance of the M-Marsh and Schnider models incorporated in commercially available target-controlled infusion (TCI) pumps was not evaluated in underweight patients. METHODS: : Thirty underweight patients undergoing elective surgery were randomly allocated to receive propofol via TCI using the M-Marsh or Schnider models. The target effect-site concentrations (Ces) of propofol were, in order, 2.5, 3, 4, 5, 6 and 2 µg ml -1 . Arterial blood samples were obtained at least 7 min after achieving each pseudo-steady-state. RESULTS: A total of 172 plasma samples were used to determine the predictive performance of both models. The pooled median (95% confidence interval) biases and inaccuracies at a target Ce ≤ 3 µg ml -1 were -22.6 (-28.8 to -12.6) and 31.9 (24.8-36.8) for the M-Marsh model and 9.0 (1.7-16.4) and 28.5 (21.7-32.8) for the Schnider model, respectively. These values at Ce ≥ 4 µg ml -1 were -9.6 (-16.0 to -6.0) and 24.7 (21.1-27.9) for the M-Marsh model and 19.8 (12.9-25.7) and 36.2 (31.4-39.7) for the Schnider model, respectively. CONCLUSIONS: The pooled biases and inaccuracies of both models were clinically acceptable. However, the M-Marsh and Schnider models consistently produced negatively and positively biased predictions, respectively, in underweight patients. In particular, the M-Marsh model showed greater inaccuracy at target Ce ≤ 3 µg ml -1 and the Schnider model showed greater inaccuracy at target Ce ≥ 4 µg ml -1 . Therefore, it is necessary to develop a new pharmacokinetic model for propofol in underweight patients. CLINICAL TRIAL REGISTRATION: KCT0001502.

Early detection of synchronous esophageal squamous cell neoplasm (ESCN) in head and neck squamous cell carcinoma (HNSCC) patients can significantly affect their prognosis. We investigated the prevalence of synchronous ESCN and the risk factors for developing ESCN in patients with HNSCC, and evaluated the effect of routine endoscopic screening in these patients. Subjects who were diagnosed as HNSCC from May 2010 to January 2014 were eligible. All patients underwent conventional white light endoscopic examinations with narrow band imaging and Lugol chromoendoscopy. Among 458 subjects screened, 28 synchronous ESCN were detected in 24 patients (5.2%). The prevalence of ESCN was greatest in patients with hypopharyngeal cancer (20.9%). In multivariate analysis, pyriform sinus involvement was independent risk factor for developing synchronous ESCN (odds ratio 171.2, P < 0.001). During the follow-up period (median, 24 months), the 3-year overall survival rates was significantly lower in patients with ESCN than in patients without ESCN (54.2% vs. 78.3%, P = 0.0013). Routine endoscopic screening for detecting synchronous ESCN should be recommended for patients with HNSCC, especially those with pyriform sinus involvement.

RESUMEN
BACKGROUND: Adequate nutritional support for patients undergoing major surgery significantly affects postoperative recovery. Data on enteral feeding after liver transplantation (LT) are scarce. The aim of this work was to determine the efficacy and complications of feeding tubes inserted with the use of fluoroscopic assistance, endoscopic assistance, or transperitoneal jejunostomy in patients who underwent LT. METHODS: From January 2008 to August 2013, 2,058 LTs were performed at Asan Medical Center, Seoul, Korea. Enteral feeding tubes were inserted in 155 patients (7.5%) after LT: with the use of fluoroscopic placement in 81 (52%), endoscopic placement in 49 (32%), and transperitoneal jejunostomy in 25 (16%). We retrospectively analyzed the efficacy and complications of enteral feeding tubes. RESULTS: The median age was 55 years (interquartile range [IQR] 49-60). Enteral feeding indications were a high risk of gastric aspiration (n = 90), gastric stasis (n = 27), pneumonia (n = 23), gastrointestinal bleeding (n = 12), and bowel rest (n = 3). Median enteral feeding durations were 14.5 days (IQR 8.0-30.7) for fluoroscopic placement, 20.0 days (IQR 8.0-40.0) for endoscopic placement, and 37.5 days (IQR 18.2-86.2) for transperitoneal jejunostomy. Times to establishment of oral feeding were 13.0 days (IQR 6.2-25.7) for fluoroscopic placement, 24.0 days (IQR 10.5-43.5) for endoscopic placement, and 37.0 days (IQR 17.0-64.2) for transperitoneal jejunostomy. After tube insertion, tube dislocation and blockage occurred in 34 patients (22%) and 16 patients (25%), respectively. CONCLUSIONS: Enteral feeding tube insertion in patients who can not maintain a nasogastric tube or start oral intake for a long time is important for nutritional support after LT. Proper feeding method selection according to patient condition can help patients by improving nutritional support after major operations such as LT.

BACKGROUND: The beneficial effect of biofeedback therapy (BFT) over a period of more than 2 years has not been studied in a large group of patients. The aim of this study was to evaluate the long-term efficacy of BFT for dyssynergic defecation (DD). METHODS: We evaluated the results for 347 consecutive constipated patients with DD who underwent BFT for a median of five sessions between 2004 and 2009. Initial responses were assessed immediately after the completion of BFT. A responder was defined as a subject with at least a three-point improvement from before to after BFT on an 11-point global bowel satisfaction (GBS) scale, or a two-point improvement if the baseline GBS was more than six points. The probability of remaining a responder was estimated by non-parametric maximum likelihood estimation. KEY RESULTS: The initial response rate to BFT was 72.3% (n = 251), Parkinson's disease and higher baseline GBS scores were associated with initial non-response. The long-term efficacy of BFT was analyzed in 103 patients who were followed up for more than 6 months; the initial effects of BFT were maintained in 85 of the patients (82.5%) during a median of 44 months of follow-up (IQR = 12-68). The probability of remaining a responder was 60% at 2 years, and 58% at 5 years. CONCLUSIONS & INFERENCES: The efficacy of BFT is maintained for more than 2 years after BFT in a considerable proportion of constipated patients with DD. BFT is effective and durable treatment for managing DD.

BACKGROUND: Although gastric cancer screening is common among countries with a high prevalence of gastric cancer, there is little data to support the effectiveness of this screening. This study was designed to determine the differences in stage at diagnosis of gastric cancer according to the screening history and screening method (upper gastrointestinal series (UGIS) vs endoscopy). METHODS: The study population was derived from the National Cancer Screening Programme (NCSP), a nationwide organised screening programme in Korea. The study cohort consisted of 19 168 gastric cancer patients who had been diagnosed in 2007 and who were invited to undergo gastric cancer screening via the NCSP between 2002 and 2007. RESULTS: Compared with never-screened patients, the odds ratios for being diagnosed with localised gastric cancer in endoscopy-screened patients and UGIS-screened patients were 2.10 (95% CI=1.90-2.33) and 1.24 (95% CI=1.13-1.36), respectively. CONCLUSIONS: Screening by endoscopy was more strongly associated with a diagnosis of localised stage gastric cancer compared with screening by UGIS.

BACKGROUND: High-resolution manometry using the Chicago classification, which utilizes parameters including integrated relaxation pressure (IRP), distal contractile integral (DCI), and contractile front velocity (CFV), shows better diagnostic ability than previous conventional criteria. However, the current normal cut-off values for the Chicago classification are based on individuals aged 19-48 years and do not include older people. Here, we aimed to assess the normal values for the Chicago classification in individuals aged 20-67 years and compare the parameters across age groups. METHODS: Fifty-four asymptomatic healthy individuals (27 male and 27 female; age range. 20-67 years) were prospectively enrolled. To evaluate the effect of age and sex on manometric profiles, we attempted to enroll equal numbers of male and female subjects for each decade. Manometry was performed in both the supine and sitting positions. KEY RESULTS: The distal latency (DL) was significantly shorter with increasing age in both measurement positions. Furthermore, IRP was significantly higher with increasing age in both positions. Spearman's ranked correlation coefficient analysis indicated that DCI and IRP in both positions were positively correlated with age. CONCLUSIONS & INFERENCES: Age affects the key parameters currently used in the Chicago classification, including IRP, DCI, and DL. Larger prospective studies with older subjects are needed to determine the age-related normal values for the Chicago classification system.

OBJECTIVE: This study assessed trends in the incidence of and survival rates for oral cavity cancer in the Korean population. MATERIALS AND METHODS: Data from the Korea Central Cancer Registry were extracted for 10,282 patients diagnosed with oral cavity cancer (C01-C06) between 1999 and 2010 to evaluate the age-standardised incidence rate, annual percentage change (APC) and 5-year relative survival rate (RSR) according to gender and age. RESULTS: In males, the incidence rate slightly decreased [APC of -0.2% (P = 0.6427)]; in females, the incidence rate increased [APC of 3.1% (P < 0.05)]. In males and females, the incidence of oral tongue cancer (C02) significantly increased [APC of 2.2% and 4.1%, respectively (P < 0.05)]. This increase in oral tongue cancer incidence was most prominent in the younger age group (<40 years, APC = 6.1%, P < 0.05). The incidence of buccal cheek cancer increased only among males [APC of 4.8% (P < 0.05)]. The 5-year RSR improved from 42.7% (1993-1995) to 59.5% (2006-2010), corresponding to an increase of 16.8% from 1993 to 2010 (P < 0.05). CONCLUSION: The incidence of oral cavity cancer in females increased, whereas it stabilised or decreased in males. However, the incidence of oral tongue cancer increased in both males and females, especially in the younger age group.

BACKGROUND: High-resolution manometry (HRM) based on spatiotemporal plots is increasingly being used. The aim this study was to evaluate, for the first time, the influence of gender, with adjustment for age, body mass index (BMI), and vaginal delivery, on anorectal functions in asymptomatic adults. METHODS: Fifty-four asymptomatic healthy subjects (M : F = 27 : 27; age = 20-67 years) who were matched by age and gender were enrolled prospectively. We evaluated anorectal pressures, rectal sensation using a HRM probe, and balloon expulsion time. Multivariate linear regression analysis was performed to identify the independent effects of each factor. KEY RESULTS: Anal resting pressure (median [IQR]; 32 [18] vs 46 [17] mmHg, p < 0.001), anal squeeze pressure (75 [28] vs 178 [72] mmHg, p < 0.001), rectal pressure (33 [16] vs 53 [46] mmHg, p = 0.009) and anal pressure (16 [17] vs 30 [36] mmHg, p = 0.019) during simulated evacuation with rectal distention, and the threshold for the desire to defecate (60 [20] vs 80 [60] mL, p = 0.020) were significantly lower in women than in men. BMI was positively correlated with anal resting pressure (95% CI: 0.598-2.947) and negatively correlated with the threshold for first sensation (95% CI: -0.099 to -0.015). Vaginal delivery did not affect any of the anorectal HRM parameters. CONCLUSIONS & INFERENCES: HRM parameters may be associated with gender and BMI. Therefore, gender and BMI should be taken into consideration when interpreting HRM results.

PURPOSE: A prospective cohort study was conducted to analyze whether self-reported fatigue predicts overall survival in patients with esophageal cancer. METHODS: Patients enrolled in the Mayo Clinic Esophageal Adenocarcinoma and Barrett's Esophagus Registry between September 2001 and January 2009 who completed a baseline quality of life instrument were eligible for evaluation. The fatigue component was scored on a 0-10 scale, with 0 as extreme fatigue. Patients were categorized as having a decreased energy level if they reported a score of ≤ 5. Fatigue scores ≥ 6 reflect normal levels of energy. RESULTS: Data from a total of 659 enrolled patients were analyzed. A total of 392 (59 %) and 267 (41 %) patients reported decreased and normal energy, respectively. Univariate analysis indicates patients with normal energy had improved 5-year survival compared to patients with decreased energy (37 vs 28 %, hazard ratio (HR) 0.74, p = 0.006). Among the patients with locally advanced disease, the same relationship was seen (28 vs 17 %, HR = 0.67, p = 0.003); this remained significant on multivariate analysis (HR = 0.71, p = 0.015). CONCLUSIONS: A decreased energy level is associated with poor survival in patients with esophageal cancer. Thus, patients with high levels of fatigue should be referred for psychological support and be considered for therapy aimed at amelioration of fatigue symptoms.

The aim of this study was to investigate the possibility of appendiceal orifice inflammation (AOI) as a preceding lesion in the development of ulcerative colitis. A total of 20 patients were identified (mean age 41.2 years; 11 males) who had ulcerative colitis-like inflammatory lesions at the appendiceal orifice without concomitant typical features of ulcerative colitis, such as rectal involvement. A total of 19 patients were followed up endoscopically for a mean duration of 18.4 months (range 2â-â84 months). Typical ulcerative colitis developed in five patients (25â%; four proctitis, one pancolitis) in a mean time of 18.4 months (range 2â-â36 months). Negative conversion of all inflammatory lesions occurred in seven patients (35â%) after a mean follow-up of 20 months (range 3â-â84 months). In the remaining seven patients (35â%), initial lesions did not progress to ulcerative colitis and did not go into remission during a mean follow-up of 16.9 months (range 2â-â42 months). These results suggest that, at least in some cases, AOI precedes development of ulcerative colitis.

The Busan cancer registry was established in 1996; cancer registration is done by passive and active methods. The registry contributed survival data for 48 cancer sites or types registered during 1996-2001. Follow-up information has been gleaned predominantly by passive methods with median follow-up ranging between 1-57 months for various cancers. The proportion with histologically verified diagnosis for different cancers ranged between 20-100%; death certificates only (DCOs) comprised 0-53%; 47-100% of total registered cases were included for survival analysis. The top-ranking cancers on 5-year age-standardized relative survival rates were penis (94%), thyroid (91%), non-melanoma skin (89%), placenta (86%), breast (76%), Hodgkin lymphoma (75%) and testis (72%). Five-year relative survival by age group showed a decreasing trend with increasing age groups for cancers of the nasopharynx, gall bladder, lung, bone, soft tissue, breast, cervix, corpus uteri, thyroid, multiple myeloma, lymphoid leukaemia and myeloid leukaemia or was fluctuating for other cancers.

The incidence of adenocarcinoma of the esophagogastric junction (AEG) has been increasing in Western countries. It is unclear, however, whether similar changes are occurring in Asia. We therefore investigated the incidence of AEG in Korea, and assessed the clinical characteristics of three types of AEG based on Siewert's classification. We retrospectively reviewed the medical records of 16 811 patients diagnosed with esophageal squamous cell carcinoma (ESC, n= 1450) or gastric noncardiac adenocarcinoma (GNCA, n= 14 751) between 1992 and 2006. The patients were divided into three 5-year cohorts (cohort A [1992-1996], n= 2734, cohort B [1997-2001], n= 5727, and cohort C [2002-2006], n= 8350), and the ratios of AEG (n= 610) to non-AEG (ESC and GNCA) in each cohort were compared. Using Siewert's classification, the tumors were categorized into one of three types, and patient demographic features and 5-year survival rates were compared. The ratio of AEG to non-AEG cases did not change over time (0.037, 0.034, and 0.039 for cohorts A, B, and C, respectively; P= 0.40). Of the 610 patients with AEG, 23 (3.7%) had type 1 tumors, 47 (7.7%) had type 2, and 540 (88.5%) had type 3. The 5-year survival rate of patients with type 1 AEG was much lower (4.8 +/- 4.7%) than that of those with type 2 (47.9 +/- 7.8%) and type 3 (47.4 +/- 2.5%) tumors. Unlike in Western countries, the ratio of AEG to non-AEG cases has not increased over time in Korea. Type 1 AEG was rarer and associated with a more unfavorable prognosis in Korea than in Western countries.
