Abstract
BACKGROUND Frailty is common in older patients with cancer; however, its clinical impact on the survival outcomes has seldom been examined in these patients. This study aimed to investigate the association of frailty with the survival outcomes and surgical complications in older patients with cancer after elective abdominal surgery in Taiwan. METHODS We prospectively enrolled 345 consecutive patients aged ≥65 years with newly diagnosed cancer who underwent elective abdominal surgery between 2016 and 2018. They were allocated into the fit, pre-frail, and frail groups according to comprehensive geriatric assessment (CGA) findings. RESULTS The fit, pre-frail, and frail groups comprised 62 (18.0%), 181 (52.5%), and 102 (29.5%) patients, respectively. After a median follow-up of 48 (interquartile range, 40-53) months, the mortality rates were 12.9%, 31.5%, and 43.1%, respectively. The adjusted hazard ratio was 1.57 (95% confidence interval [CI], 0.73-3.39; p = 0.25) and 2.87 (95% CI, 1.10-5.35; p = 0.028) when the pre-frail and frail groups were compared with the fit group, respectively. The frail group had a significantly increased risk for a prolonged hospital stay (adjusted odds ratio, 2.22; 95% CI, 1.05-4.69; p = 0.022) compared with the fit group. CONCLUSION Pretreatment frailty was significantly associated with worse survival outcomes and more surgical complications, with prolonged hospital stay, in the older patients with cancer after elective abdominal surgery. Preoperative frailty assessment can assist physicians in identifying patients at a high risk for surgical complications and predicting the survival outcomes of older patients with cancer.

Abstract
AIM To determine the associations of intravoxel incoherent motion (IVIM) parameters with expression of programmed cell death-1 (PD-1) and programmed cell death ligand-1 (PD-L1), and evaluate the performance of the combined model established based on IVIM and clinicopathological parameters in predicting PD-L1and PD-1 status of cervical cancer (CC) patients. MATERIALS AND METHODS Seventy-eight consecutive CC patients were enrolled prospectively and underwent magnetic resonance imaging (MRI) including IVIM. IVIM quantitative parameters were measured, compared, and correlated with PD-L1 and PD-1 expression. Independent factors related to PD-L1 and PD-1 positivity were identified and were used to establish the combined model. The combined model's diagnostic performance was evaluated using the receiver operating characteristic (ROC) analysis. The Shapley additive explanation (SHAP) algorithm was used to explain the contribution of each parameter in the combined model. RESULTS The real diffusion coefficient (D) value was significantly lower in the PD-L1-positive group than in the PD-L1-negative group (0.64 ± 0.12 versus 0.72 ± 0.11, p=0.021). The PD-1-positive and PD-1-negative groups showed similar trends (0.63 ± 0.13 versus 0.73 ± 0.09, p=0.003). Parametrial invasion, lymph node status, pathological grade, FIGO (International Federation of Gynecology and Obstetrics) staging, and D values were independently associated with PD-L1 and PD-1expression. A combined model incorporating these parameters showed good discrimination with the sensitivity, specificity of 90.9%, 82.6% for PD-L1, and 93.5%, 72% for PD-1. According to the SHAP value, FIGO staging and pathological grade were the most influential features of the prediction model. CONCLUSION IVIM parameters were found to correlate with PD-L1 and PD-1 expression. The combined model, incorporating parametrial invasion, lymph node status, pathological grade, FIGO staging, and D values, showed good discrimination in predicting PD-L1 and PD-1 status, providing the basis for CC immunotherapy.

Abstract
SUMMARY To minimize donor-site damage, robot-assisted (RA) deep inferior epigastric perforator (DIEP) flap harvest has been suggested. Current robotic approaches favor port placement, which either does not allow a bilateral DIEP flap harvest through the same ports or necessitates additional scars. In this article, the authors propose a modification of port configuration. In a retrospective controlled cohort study, RA-DIEP and conventional DIEP surgery were compared. The perforator and pedicle were visualized conventionally until the level behind the rectus abdominis muscle. Next, the robotic system was installed to dissect the retromuscular pedicle. The authors assessed patient age; body mass index; history of smoking, diabetes mellitus, and hypertension; and additional surgical time. The length of the anterior rectus sheath (ARS) incision was measured. Pain was quantified using the visual analogue scale. Donor-site complications were assessed. Thirteen RA-DIEP flaps (11 unilateral and two bilateral) and 87 conventional DIEP flaps were harvested without flap loss. The bilateral DIEP flaps were raised without readjustments of the ports. The mean time for pedicle dissection was 53.2 ± 13.4 minutes. The length of the ARS incision was significantly shorter in the RA-DIEP group (2.67 ± 1.13 cm versus 8.14 ± 1.69 cm; 304.87% difference; P < 0.0001). There was no statistical difference in postoperative pain (day 1: 1.9 ± 0.9 versus 2.9 ± 1.6, P = 0.094; day 2: 1.8 ± 1.2 versus 2.3 ± 1.5, P = 0.319; day 3: 1.6 ± 0.9 versus 2.0 ± 1.3, P = 0.444). Preliminary results show that the authors' RA-DIEP approach is safe and allows dissection of bilateral RA-DIEP flaps with short ARS incision lengths. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
BACKGROUND Postoperative delirium (POD) is a common surgical complication in elderly patients. As frailty is a relatively novel concept, its clinical significance for POD has seldom been examined. This study aimed to investigate the association between frailty and POD in aged cancer patients undergoing elective abdominal surgery in Taiwan. METHODS We prospectively enrolled 345 consecutive patients aged ≥65 years with newly diagnosed cancer who underwent elective abdominal surgery between 2016 and 2018. Frailty assessment was performed using the Comprehensive Geriatric Assessment (CGA). POD was assessed daily using the Confusion Assessment Method from postoperative day 1 until discharge. Patients were allocated into fit and frail groups. RESULTS POD occurred in 19 (5.5%) of 345 patients. POD incidence was 1.6%, 3.1%, 4.8%, 11.5%, and 10.0% in patients with 0, 1, 2, 3, and 4+ frail conditions, respectively, which presented a positive linear correlation among patients with an increased number of frail conditions and POD incidence. Based on CGA, 159 (46.1%) and 186 (53.9%) patients were allocated to fit and frail groups, respectively. POD incidence was 2.5% and 8.1% for the fit and frail groups, respectively. Frailty status was an independent risk factor for POD occurrence in multivariate analysis. CONCLUSION Our study identified frailty as an independent risk factor for POD in aged Taiwanese cancer patients undergoing elective abdominal surgery. Given the high prevalence of frailty among older cancer patients, preoperative assessment is important to identify high risk of POD and to improve the quality of postoperative care.

Abstract
BACKGROUND Postoperative delirium (POD) is a common complication in older adults, with unknown epidemiology and effects on surgical outcomes in Asian geriatric cancer patients. This study evaluated incidence, risk factors, and association between adverse surgical outcomes and POD after intra-abdominal cancer surgery in Taiwan. METHODS Overall, 345 patients aged ≥65 years who underwent elective abdominal cancer surgery at a medical center in Taiwan were prospectively enrolled. Delirium was assessed daily using the Confusion Assessment Method. Univariate and multivariate logistic regression analyses investigated risk factors for POD occurrence and estimated the association with adverse surgical outcomes. RESULTS POD occurred in 19 (5.5%) of the 345 patients. Age ≥73 years, Charlson comorbidity index ≥3, and operative time >428 min were independent predictors for POD occurrence. Patients presenting with one, two, and three risk factors had 4.1-fold (95% confidence interval [CI], 0.4-35.8, p = 0.20), 17.4-fold (95% CI, 2.2-138, p = 0.007), and 30.8-fold likelihood (95% CI, 2.9-321, p = 0.004) for POD occurrence, respectively. Patients with POD had a higher probability of prolonged hospital stay (adjusted odds ratio [OR] 2.8; 95% CI, 1.0-8.1; p = 0.037), intensive care stay (adjusted OR: 3.9; 95% CI, 1.5-10.5; p = 0.008), 30-day readmission (adjusted OR 3.1; 95% CI, 1.1-9.7; p = 0.039), and 90-day postoperative death (adjusted OR: 4.2; 95% CI, 1.0-17.7; p = 0.041). CONCLUSION POD occurrence was significantly associated with adverse surgical outcomes in geriatric patients undergoing elective abdominal cancer surgery, highlighting the importance of early POD identification in geriatric patients to improve postoperative care quality.

Abstract
We previously developed a Chang Gung Memorial Hospital (CGMH) model to predict the 1-year postoperative mortality risk in patients with solid cancer undergoing cancer surgery. This study aimed to externally validate the CGMH score for survival outcome and surgical complication prediction in a prospective patient cohort. A total of 345 consecutive patients aged ≥65 years who underwent elective abdominal surgery for cancer treatment were prospectively enrolled. Patients were categorized into the low, intermediate, high, and very high-risk groups according to the CGMH score for comparison. The postoperative 1-year mortality rate was 12.5% in the entire cohort. The postoperative 1-year mortality rates were 0%, 2.2%, 14.0%, and 31.6% among patients in the low, intermediate, high, and very-high risk groups, respectively. The c-statistic of the CGMH model was 0.82 (95% confidence interval [CI], 0.76-0.88) for predicting the 1-year mortality risk. Hazard ratios for overall survival were 3.73 (95% CI, 2.11-6.57; P<0.001) and 10.1 (95% CI, 5.84-17.6; P<0.001) when comparing the high and very-high risk groups with the low/intermediate risk groups, respectively. Patients in the higher CGMH risk groups had higher risks of adverse surgical outcomes in terms of longer length of hospital stay, major surgical complications, postoperative intensive care unit stay, and in-hospital death. The CGMH model accurately predicted thesurvival probabilityand risk of adverse surgical outcomes in older patients with cancer undergoing elective abdominal surgery. Our study justifies the prospective use of the CGMH model for survival outcome and safety profile predictionfor cancer surgery in older patients.

Abstract
Background: Concurrent acute cholecystitis and acute cholangitis is a unique clinical situation. We tried to investigate the optimal timing of cholecystectomy after adequate biliary drainage under this condition. Methods: From January 2012 to November 2017, we retrospectively screened all in-hospitalized patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) and then identified patients with concurrent acute cholecystitis and acute cholangitis from the cohort. The selected patients were stratified into two groups: one-stage intervention (OSI) group (intended laparoscopic cholecystectomy at the same hospitalization) vs. two-stage intervention (TSI) group (interval intended laparoscopic cholecystectomy). Interrogated outcomes included recurrent biliary events, length of hospitalization, and surgical outcomes. Results: There were 147 patients ultimately enrolled for analysis (OSI vs. TSI, 96 vs. 51). Regarding surgical outcomes, there was no significant difference between the OSI group and TSI group, including intraoperative blood transfusion (1.0% vs. 2.0%, p = 1.000), conversion to open procedure (3.1% vs. 7.8%, p = 0.236), postoperative complication (6.3% vs. 11.8%, p = 0.342), operation time (118.0 min vs. 125.8 min, p = 0.869), and postoperative days until discharge (3.37 days vs. 4.02 days, p = 0.643). In the RBE analysis, the OSI group presented a significantly lower incidence of overall RBE (5.2% vs. 41.2%, p < 0.001) than the TSI group. Conclusions: Patients with an initial diagnosis of concurrent acute cholecystitis and cholangitis undergoing cholecystectomy after ERCP drainage during the same hospitalization period may receive some benefit in terms of clinical outcomes.

Abstract
In recent years, many image-based approaches have been proposed to classify plant species. Most methods utilized red green blue (RGB) imaging materials and designed custom features to classify the plant images using machine learning algorithms. Those works primarily focused on analyzing single-leaf images instead of live-crown images. Without considering the additional features of the leaves' color and spatial pattern, they failed to handle cases that contained leaves similar in appearance due to the limited spectral information of RGB imaging. To tackle this dilemma, this study proposes a novel framework that combines hyperspectral imaging (HSI) and deep learning techniques for plant image classification. We built a plant image dataset containing 1,500 images of 30 different plant species taken by a 470-900 nm hyperspectral camera and designed a lightweight conventional neural network (CNN) model (LtCNN) to perform image classification. Several state-of-art CNN classifiers are chosen for comparison. The impact of using different band combinations as the network input is also investigated. Results show that using simulated RGB images achieves a kappa coefficient of nearly 0.90 while using the combination of 3-band RGB and 3-band near-infrared images can improve to 0.95. It is also found that the proposed LtCNN can obtain a satisfactory performance of plant classification (kappa = 0.95) using critical spectral features of the green edge (591 nm), red-edge (682 nm), and near-infrared (762 nm) bands. This study also demonstrates the excellent adaptability of the LtCNN model in recognizing leaf features of plant live-crown images while using a relatively smaller number of training samples than complex CNN models such as AlexNet, GoogLeNet, and VGGNet.

Abstract
Gastrointestinal stromal tumors (GISTs), leiomyomas, and schwannomas are the most common gastric subepithelial tumors (GSETs) with similar endoscopic findings. Preoperative prediction of GSETs is difficult. This study analyzed and predicted GSET diagnosis through a retrospective review of 395 patients who underwent surgical resection of GISTs, leiomyomas, and schwannomas measuring 2–10 cm. GSETs were divided by size (group 2–5, >2 and ≤5 cm; group 5–10, >5 and ≤10 cm) for analysis. Demographics, clinical symptoms, and images were analyzed. A recursive partitioning analysis (RPA) was used to identify optimal classifications for specific GSET diagnoses. GIST patients were relatively older than other patients. Both groups had higher proportions of UGI bleeding, lower hemoglobin (Hb) levels, and a higher ratio of necrosis on their computed tomography (CT) scans. The RPA tree showed that (a) age ≤ 55, Hb ≥ 10.7, and CT necrosis; (b) age ≤ 55 and Hb < 10.7; (c) age >55 and Hb < 12.9; and (d) age >55 and CT hetero-/homogeneity can predict high GIST risk in group 2–5. Positive or negative CT necrosis, with age >55, can predict high GIST risk in group 5–10. GIST patients were older and presented with low Hb levels and tumor necrosis. In RPA, the accuracy reached 85% and 89% in groups 2–5 and 5–10, respectively.

Abstract
BACKGROUND Investigation of lymph node micrometastasis (mN) of gastric cancer has been focused on either T1 disease or T1-4N0 disease. Yet, it is unclear whether standard management algorithm toward poorly differentiated gastric cancer (PDGC) is more vulnerable to existence of mN, given its inherently biological aggressiveness, as compared with other histological types. PATIENTS AND METHODS A surgical series (n = 3456) of gastric cancer categorized by histological differentiation was enrolled to analyze survival stratification. Of them, a cohort of T1-T4 N0 PDGC (n = 100) were subjected to cytokeratin immunohistochemistry, a surrogate of mN. RESULTS Cancer-specific survival by AJCC8 staging system could be nicely differentiated in both well-/moderately differentiated and signet ring cell types, while those between stage IA versus IB (p = 0.105), and stage IB versus IIA (p = 0.141) in PDGC could not. Thirteen (13%) out of 100 node-negative PDGC cases exhibited mN, with 5, 2, 5 and 1 cases occurring in T1, T2, T3, and T4 stage, respectively, without identifiable contributing factors. Prognostic performance of AJCC8 working upon PDGC became more discriminative by incorporating mN, as hazard ratio of stage IIIC referenced to stage IA increased from 43 to 78. CONCLUSION Defective discriminative survival of PDGC by standard staging algorithm prompted us to survey mN occurring in T1-T4N0 PDGC. The prognostic performance of AJCC8 working upon PDGC was enhanced by incorporating mN. As so, we recommend documentation of mN exclusively on node-negative PDGC that helps unveil stage migration phenomenon and switch to appropriate adjuvant therapy in need.

Abstract
Numerous strategies for perioperative nutrition therapy for patients undergoing pancreaticoduodenectomy (PD) have been proposed. This systematic review aimed to summarize the current relevant published randomized controlled trials (RCTs) evaluating different nutritional interventions via a traditional network meta-analysis (NMA) and component network meta-analysis (cNMA). EMBASE, MEDLINE, the Cochrane Library, and ClinicalTrials.gov were searched to identify the RCTs. The evaluated nutritional interventions comprised standard postoperative enteral nutrition by feeding tube (Postop-SEN), preoperative enteral feeding (Preop-EN), postoperative immunonutrients (Postop-IM), preoperative oral immunonutrient supplement (Preop-IM), and postoperative total parenteral nutrition (TPN). The primary outcomes were general, infectious, and noninfectious complications; postoperative pancreatic fistula (POPF); and delayed gastric emptying (DGE). The secondary outcomes were mortality and length of hospital stay (LOS). The NMA and cNMA were conducted with a frequentist approach. The results are presented as odds ratios (ORs) and 95% confidence intervals (CIs). Two primary outcomes, infectious complications and POPF, were positively influenced by nutritional interventions. Preop-EN plus Postop-SEN (OR 0.11; 95% CI 0.02~0.72), Preop-IM (OR 0.22; 95% CI 0.08~0.62), and Preop-IM plus Postop-IM (OR 0.11; 95% CI 0.03~0.37) were all demonstrated to be associated with a decrease in infectious complications. Postop-TPN (OR 0.37; 95% CI 0.19~0.71) and Preop-IM plus Postop-IM (OR 0.21; 95% CI 0.06~0.77) were clinically beneficial for the prevention of POPF. While enteral feeding and TPN may decrease infectious complications and POPF, respectively, Preop-IM plus Postop-IM may provide the best clinical benefit for patients undergoing PD, as this approach decreases the incidence of both the aforementioned adverse effects.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) with associated procedures and endoscopic retrograde cholangiopancreatography (ERCP) have been the standard treatments for both common and rare biliary diseases. Mirizzi syndrome (MS) is a rare and complex biliary condition. We report our experience with MS treatment and investigate the value of laparoscopic procedures and ERCP in patient management. METHODS From 2004 to 2017, 100 consecutive patients with MS were diagnosed by ERCP and underwent surgery in a referral center. Sixty patients were treated with intended LC, and 40 patients were treated with open cholecystectomy (OC). The clinical manifestations, ERCP and associated procedures, surgical procedures, and postoperative outcomes were investigated. RESULTS The surgical mortality rate was 1%, while the surgical morbidity rate was 15%. The patients treated with intended LC suffered from less morbidity (5%). The percentage of postoperative residual biliary stones was 32% (n = 32), and only three patients underwent re-operation (laparotomy) for stone removal. The laparotomy conversion rate in the intended LC group was 16.7% (10/60). The length of hospitalization for the patients with successful LC was significantly shorter than that for the patients with conversion and intended OC. Csendes classification was a risk factor for conversion from LC to OC (type I vs types II to V, P < .0001). CONCLUSIONS A combination of a laparoscopic procedure and ERCP may provide therapeutic benefits for patients with MS.

Abstract
BACKGROUND/AIM We compared the adequacy of five nutrition assessment tools with respect to their predictive value in patients with locally advanced gastric cancer (GC) receiving radical surgery. PATIENTS AND METHODS Five nutrition assessment tools-Glasgow prognostic score (GPS), malnutritional universal screening tool (MUST), nutritional risk screening, patient generated subjective global assessment (PG-SGA), and prognostic nutritional index (PNI)-were assessed preoperatively for stage III GC patients. The correlation between postoperative events and nutritional status was further analyzed. RESULTS Most of the nutritional tools accurately predicted length of hospital stay and grade 3 or higher surgical complications, while only the GPS correlated with 30-day readmission and surgical complications. The PG-SGA performed the poorest among the five tools and failed to predict any postoperative event. CONCLUSION The application of GPS is recommended as a prognostic index for patients with locally advanced GC prior to radical surgery.

Abstract
BACKGROUND/AIM This study was designed to clarify the value of routine alpha-fetoprotein (AFP) testing for patients with gastric cancer (GC). PATIENTS AND METHODS A total of 905 patients with newly diagnosed GC and available pretreatment carcinoembryonic antigen (CEA), cancer-related antigen 19-9 (CA19-9), and AFP data from 2010 to 2016 were collected for comparison of tumor stage and survival. RESULTS In total, 139 patients (15.4%), 155 patients (17.1%), and 27 patients (3.0%) had elevated CEA, CA19-9, and AFP levels, respectively. The c-index values of elevated AFP levels in predicting stage IV disease and the 1-year mortality rate were 0.564 (95%CI=0.520-0.608) and 0.594 (95%CI=0.553-0.635), respectively, which were significantly lower than those of CEA (0.673 and 0.665) and CA19-9 (0.619 and 0.618). CONCLUSION Elevated AFP is rare in patients with newly diagnosed GC. Routine AFP sampling would not provide a higher survival prediction in GC patients than CEA or CA19-9.

Abstract
BACKGROUND Everolimus, an immunosuppressant, is approved for the treatment of advanced renal cell carcinoma, metastatic hormone receptor-positive breast cancer, and pancreatic neuroendocrine tumors (P-NETs) but has been reported to be related to hepatitis B reactivation. Here, we present the first case of fatal fulminant hepatitis B reactivation in a man with P-NET accompanied by multiple liver metastases who received everolimus and octreotide long-acting repeatable (LAR). CASE PRESENTATION A 45-year-old male had a history of chronic hepatitis B infection. He was found to have a complicated liver cyst incidentally, and then he underwent biopsy, which disclosed a grade 2 neuroendocrine tumor (NET). Subsequent MRI of the abdomen and PET revealed a solid mass at the pancreatic tail with numerous liver tumors favoring metastases and peripancreatic lymph node metastases. Transarterial chemoembolization (TACE) of the right lobe of the liver was performed, and he started to take 5 mg everolimus twice a day and 20 mg octreotide LAR every month 8 days after the 1st TACE. No hepatitis B virus (HBV) prophylaxis treatment was administered. He then underwent laparoscopic distal pancreatectomy and splenectomy three and half months after the initial treatment of everolimus. He continued everolimus 5 mg twice a day and octreotide 20 mg every month after the operation. Three months later, hepatic failure occurred due to acute hepatitis B flare-up-related fulminant hepatic failure since other possible causes of hepatic failure were excluded. Five days after hepatic failure presented, hepatic failure was apparent, and pulseless ventricular tachycardia occurred. The patient expired after failed resuscitation. CONCLUSION A literature review of everolimus-related hepatitis B reactivation was conducted. In P-NET patients with chronic hepatitis B who will undergo everolimus treatment, HBV prophylaxis should be considered since fatal hepatitis B reactivation might occur under rare conditions.

Abstract
Cancer is one of the common diseases. Quantitative biomarkers extracted from standard-of-care computed tomography (CT) scan can create a robust clinical decision tool for the diagnosis of hepatocellular carcinoma (HCC). According to the current clinical methods, the situation usually accounts for high expenditure of time and resources. To improve the current clinical diagnosis and therapeutic procedure, this paper proposes a deep learning-based approach, called Successive Encoder-Decoder (SED), to assist in the automatic interpretation of liver lesion/tumor segmentation through CT images. The SED framework consists of two different encoder-decoder networks connected in series. The first network aims to remove unwanted voxels and organs and to extract liver locations from CT images. The second network uses the results of the first network to further segment the lesions. For practical purpose, the predicted lesions on individual CTs were extracted and reconstructed on 3D images. The experiments conducted on 4300 CT images and LiTS dataset demonstrate that the liver segmentation and the tumor prediction achieved 0.92 and 0.75 in Dice score, respectively, by as-proposed SED method.

Abstract
BACKGROUND AND AIM Given that a wide variation in tumor response rates and survival times suggests heterogeneity among the patients with advanced pancreatic cancer (APC) who underwent second-line (L2) chemotherapy, it is a challenge in clinical practice to identify patients who will receive the most benefit from L2 treatment. METHODS We selected 183 APC patients who received L2 palliative chemotherapy between 2010 and 2016 from a medical center as the development cohort. A Cox proportional hazard model was used to identify the prognostic factors and construct the nomogram. An independent cohort of 166 patients from three other hospitals was selected for external validation. RESULTS The nomogram was based on eight independent prognostic factors from the multivariate Cox model: sex, Eastern Cooperative Oncology Group performance status, reason for first-line treatment discontinuation, duration of first-line treatment, neutrophil-to-lymphocyte ratio, tumor stage, body mass index, and serum carbohydrate antigen 19-9 levels at the beginning of L2 treatment. The model exhibited good discrimination ability, with a C-index of 0.733 (95% confidence interval, 0.681-0.785) and 0.724 (95% confidence interval, 0.661-0.787) in the development and validation cohorts, respectively. The calibration plots of the development and validation cohorts showed optimal agreement between model prediction and actual observation in predicting survival probability at 6 months, 1 year, and 2 years. CONCLUSIONS This study developed and externally validated a prognostic model that accurately predicts the survival outcome of APC patients before L2 palliative chemotherapy, which could assist in clinical decision-making, counseling for treatment, and most importantly, prognostic stratification of patients.

Abstract
Body composition (BC) parameters are associated with cardiometabolic diseases in children; however, the importance of BC parameters for predicting pediatric hypertension is inconclusive. This cross-sectional study aimed to compare the difference in predictive values of BC parameters and conventional anthropometric measures for pediatric hypertension in school-aged children. A total of 340 children (177 girls and 163 boys) with a mean age of 8.8 ± 1.7 years and mean body mass index (BMI) z-score of 0.50 ± 1.24 were enrolled (102 hypertensive children and 238 normotensive children). Significantly higher values of anthropometric measures (BMI, BMI z-score, BMI percentile, waist-to-height ratio) and BC parameters (body-fat percentage, muscle weight, fat mass, fat-free mass) were observed among the hypertensive subgroup compared to their normotensive counterparts. A prediction model combining fat mass ≥ 3.65 kg and fat-free mass ≥ 34.65 kg (area under the receiver operating characteristic curve = 0.688; sensitivity = 66.7%; specificity = 89.9%) performed better than BMI alone (area under the receiver operating characteristic curve = 0.649; sensitivity = 55.9%; specificity = 73.9%) in predicting hypertension. In conclusion, BC parameters are better than anthropometric measures in predicting pediatric hypertension. BC measuring is a reasonable approach for risk stratification in pediatric hypertension.

Abstract
Background Submucosal tumors (SMTs) of different etiologies exist from esophagus to rectum. Esophagogastric junction (EGJ) is one of the known difficult locations for tumor resection. Although minimally invasive surgery (MIS) is a well-established approach for gastrointestinal surgery, there is no consensus that MIS for resection of SMTs around EGJ is superior to laparotomy. We tried to clarify the factors that determine the surgeons’ choices between these two approaches. Methods From January 2002 to June 2016, 909 patients with SMTs underwent resection in our department. Among them, 119 patients (13%) had SMTs around EGJ were enrolled by retrospective review. The clinicopathological features and tumor-related parameters were reviewed and analyzed. Results The cohort was stratified into three groups according to the extent of gastrectomy and surgical approaches. The three groups are as following: major gastrectomy (n = 13), minor gastrectomy by laparotomy (n = 51), and minor gastrectomy with MIS (n = 55). The average tumor size was significantly larger in the major gastrectomy group than in the two minor gastrectomy groups; however, there was no difference between the two minor gastrectomy groups (5.33 cm, 4.07 cm, and 3.69 cm, respectively). The minor gastrectomy with MIS required least hospital stay and operation duration also. We re-stratify the two minor gastrectomy groups (n = 106) according to the orientation of SMTs around the EGJ into 4 zones. Most of SMTs located on the greater curvature side of the EGJ were resected with MIS (82% versus 18%), whereas SMTs in the other zones were resected more often by laparotomy (59% versus 41%). There was no surgical mortality within the cohort, while minor gastrectomy with MIS yielded least number of leakages among the three groups. Conclusions For SMTs around the EGJ, larger tumors (diameter of more than 5 cm) are more likely to be resected with major gastrectomy. To resect SMTs around the EGJ in a wedge-like (minor gastrectomy) fashion, tumors located other than the greater curvature side were more often resected by laparotomy. However, MIS yielded acceptable safety and surgical outcomes compared to conventional laparotomy for SMTs around the EGJ of the same size.

Abstract
BACKGROUND Determining survival outcome in advanced pancreatic ductal adenocarcinoma (aPDAC) patients receiving second-line (L2) chemotherapy is important for clinical decision-making. The Besançon group from France recently proposed a prognostic nomogram to predict overall survival (OS) for aPDAC patients receiving L2 chemotherapy. The present study aimed to externally validate the performance of the Besançon nomogram in predicting OS in an Asian cohort. METHODS We retrospectively enrolled 349 patients who received L2 chemotherapy for aPDAC between 2010 and 2016 at four institutes in Taiwan. The performance of the Besançon model in this cohort was evaluated with C-index and calibration plots. RESULTS The median OS time in our patient cohort was 4.5 months (95% confidence interval [CI], 3.0-5.0). Using the Besançon nomogram-predicted risk groups, the median OS times in the low, intermediate, and high-risk groups were 6.7 (95% CI, 5.3-8.2), 3.2 (95% CI, 2.4-3.9), and 1.7 months (95% CI, 0.6-2.7), respectively. The C-index of the predicted six- and 12-month survival probabilities for the Besançon nomogram were 0.766 (95% CI, 0.715-0.816) and 0.698 (95% CI, 0.641-0.754), respectively. The calibration plot showed that the observed six-month survival probability was close to the diagonal line, while that for 12-month survival deviated below the diagonal line compared to the survival probability predicted by the Besançon nomogram. CONCLUSIONS Although the Besançon nomogram tended to over-estimate the 12-month survival probability, our study demonstrated that the nomogram is a reliable and readily applicable model to estimate survival outcomes of aPDAC patients receiving L2 chemotherapy.

Abstract
The aim of this study was to evaluate the prevalence, the clinicopathological variables associated with probability of lung metastases, and the impact of lung metastases on survival outcome in patients with stage IV pancreatic cancer (PC) treated with palliative chemotherapy. A total of 654 patients with stage IV PC who underwent palliative chemotherapy from 2010–2016 were retrospectively enrolled in this study. Possible clinical variables associated with lung metastases and survival outcome were examined by univariate and multivariate analysis. Lung metastases were detected in 15.0% (3.4% with isolated lung metastases and 11.6% with synchronic metastases to lung and other organs). Female gender, poorly differentiated tumor grade, and large primary tumor size were independent risk factor in multivariate analysis. The median overall survival (OS) time was 6.5 months in the entire cohort, while the median OS was 11.8, 6.9, 7.7, 10.1, and 5.0 months for patients with isolated lung, isolated liver, isolated peritoneum, isolated distant lymph nodes, and multiple sites metastases, respectively. Isolated lung metastases were a better prognosticator for OS in univariate and multivariate analysis. This study utilized real-world clinical practice data to assess the prevalence, risk factors, and survival impact of lung metastases in patients with stage IV pancreatic cancer.

Abstract
BACKGROUND Radical gastrectomy and extended lymph node (D2) dissection followed by adjuvant chemotherapy is the optimal treatment for patients with stage III gastric cancer in Asian population. The clinical factors associated with patient propensity to receive adjuvant chemotherapy and outcomes were analyzed. METHODS In total, 509 patients with stage III gastric cancer who had undergone D2 surgery between 2007 and 2017 at a single medical center in Taiwan were analyzed. The patients' preoperative clinical characteristics relevant to adjuvant chemotherapy adherence were analyzed using multivariate regression. Significant variables were analyzed using recursive partitioning analysis (RPA) for identifying specific patient groups with the lowest and highest probabilities of adjuvant chemotherapy adherence. RESULTS After surgery, 361 (70.9%) patients in the cohort had received adjuvant chemotherapy. All patients were categorized into five probability groups with adherence to adjuvant chemotherapy according to age, Eastern Cooperative Oncology Group (ECOG) performance status grade, and American Society of Anesthesiologists (ASA) class, which were discovered to be independent factors in the RPA-based probability prediction. In general, adjuvant chemotherapy improved survival across broad categories of stage III gastric cancer patients (overall survival hazard ratio: 0.53-0.75 and disease-free survival hazard ratio: 0.47-0.76). CONCLUSIONS Our study identified that age, ECOG grade, and ASA class were independent clinical factors associated with patient propensity to receive adjuvant chemotherapy in stage III gastric cancer. Knowledge of the clinical factors of patients may help clinicians identify and encourage specific patients to receive the adjuvant chemotherapy.

Abstract
Purpose: Being elevated body mass index (BMI) has been considered a poor prognostic factor in patients with cancer. However, studies about the impact of elevated BMI on the survival outcome after cancer surgery have conflicting results. This study aimed to evaluate the impact of BMI on long-term postoperative survival outcome in a large cohort of Asian population with solid cancers. Methods: A total of 33,551 patients who underwent curative-intent surgery for solid cancers between January 2007 and December 2012 at four hospitals in Taiwan were included. BMI was analyzed using univariate and multivariate regression analyses to determine its association with survival outcome. Results: With a median follow-up of 43.8 (range, 1-91) months, the rate of all-cause mortality was 21.7% (n=7264 patients), while that of cancer-related mortality was 13.4% (n=4499 patients). BMI was a significant prognostic factor in multivariate analysis for overall survival (OS) and cancer-specific survival (CSS). The adjusted hazard ratio (HR) per kg/m2 was 0.922 (95% confidence interval [CI], 0.916-0.929; P<0.001) and 0.932 (95% CI, 0.924-0.940; P<0.001) for OS and CSS, respectively. Patients with BMI <17 kg/m2 had the highest postoperative mortality risk, with a hazard ratio of 3.8-fold higher for OS and 5.0-fold higher for CSS than those with BMI >35 kg/m2. Conclusions: This study showed that BMI was positively associated with survival outcome in patients with cancer who underwent radical surgery. BMI was an independent prognostic factor and can be used to risk stratify patients in Asians with solid cancers.

Abstract
In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the indications for LC under difficult conditions for each level of severity of AC. As a result of expanding the indications for LC to treat AC, it is absolutely necessary to avoid any increase in bile duct injury (BDI), particularly vasculo-biliary injury (VBI), which is known to occur at a certain rate in LC. Since the Tokyo Guidelines 2013 (TG13), an attempt has been made to assess intraoperative findings as objective indicators of surgical difficulty; based on expert consensus on these difficulty indicators, bail-out procedures (including conversion to open cholecystectomy) have been indicated for cases in which LC for AC is difficult to perform. A bail-out procedure should be chosen if, when the Calot's triangle is appropriately retracted and used as a landmark, a critical view of safety (CVS) cannot be achieved because of the presence of nondissectable scarring or severe fibrosis. We propose standardized safe steps for LC to treat AC. To achieve a CVS, it is vital to dissect at a location above (on the ventral side of) the imaginary line connecting the base of the left medial section (Segment 4) and the roof of Rouvière's sulcus and to fulfill the three criteria of CVS before dividing any structures. Achieving a CVS prevents the misidentification of the cystic duct and the common bile duct, which are most commonly confused.

Abstract
Antimicrobial therapy is a mainstay of the management for patients with acute cholangitis and/or cholecystitis. The Tokyo Guidelines 2018 (TG18) provides recommendations for the appropriate use of antimicrobials for community-acquired and healthcare-associated infections. The listed agents are for empirical therapy provided before the infecting isolates are identified. Antimicrobial agents are listed by class-definitions and TG18 severity grade I, II, and III subcategorized by clinical settings. In the era of emerging and increasing antimicrobial resistance, monitoring and updating local antibiograms is underscored. Prudent antimicrobial usage and early de-escalation or termination of antimicrobial therapy are now important parts of decision-making. What is new in TG18 is that the duration of antimicrobial therapy for both acute cholangitis and cholecystitis is systematically reviewed. Prophylactic antimicrobial usage for elective endoscopic retrograde cholangiopancreatography is no longer recommended and the section was deleted in TG18. Free full articles and mobile app of TG18 are available at: http://www.jshbps.jp/modules/en/index.php?content_id=47. Related clinical questions and references are also included.

Abstract
Although the diagnostic and severity grading criteria on the 2013 Tokyo Guidelines (TG13) are used worldwide as the primary standard for management of acute cholangitis (AC), they need to be validated through implementation and assessment in actual clinical practice. Here, we conduct a systematic review of the literature to validate the TG13 diagnostic and severity grading criteria for AC and propose TG18 criteria. While there is little evidence evaluating the TG13 criteria, they were validated through a large-scale case series study in Japan and Taiwan. Analyzing big data from this study confirmed that the diagnostic rate of AC based on the TG13 diagnostic criteria was higher than that based on the TG07 criteria, and that 30-day mortality in patients with a higher severity based on the TG13 severity grading criteria was significantly higher. Furthermore, a comparison of patients treated with early or urgent biliary drainage versus patients not treated this way showed no difference in 30-day mortality among patients with Grade I or Grade III AC, but significantly lower 30-day mortality in patients with Grade II AC who were treated with early or urgent biliary drainage. This suggests that the TG13 severity grading criteria can be used to identify Grade II patients whose prognoses may be improved through biliary drainage. The TG13 severity grading criteria may therefore be useful as an indicator for biliary drainage as well as a predictive factor when assessing the patient's prognosis. The TG13 diagnostic and severity grading criteria for AC can provide results quickly, are minimally invasive for the patients, and are inexpensive. We recommend that the TG13 criteria be adopted in the TG18 guidelines and used as standard practice in the clinical setting. Free full articles and mobile app of TG18 are available at: http://www.jshbps.jp/modules/en/index.php?content_id=47. Related clinical questions and references are also included.

Abstract
Background: Stage III gastric cancer is characterized by locally advanced disease with varying anatomic extent as measured by the 7th edition of the American Joint Committee on Cancer (AJCC) staging system. There are no prognostic factors specifically identified in patients with stage III gastric cancer following extended lymph node dissection (D2) surgery. Materials and Methods: From 2007 to 2014, 534 patients with stage III gastric cancer underwent radical gastrectomy and D2 dissection at the Chang Gung Memorial Hospital. Patients' characteristics and the impact of adjuvant chemotherapy were analyzed using univariate and multivariate analyses to identify variables associated with overall survival (OS) and disease-free survival (DFS). Results: There were 320 deaths (60.0%) and 284 recurrences (53.2%) by the end of the study. The median OS and DFS were 30.7 months (95% confidence interval [CI]: 27.5-33.9) and 26.4 months (95% CI: 21.2-31.6), respectively. The multivariate analysis identified 7 variables that were independent prognostic factors both for OS and DFS including ratio of metastatic lymph nodes to total resection lymph nodes, carcinoembryonic antigen level, Eastern Cooperative Oncology Group performance status, gastrectomy method, vascular invasion, surgical margin, and adjuvant chemotherapy. Patients with stage IIIA-IIIC disease who received adjuvant chemotherapy had better OS and DFS outcomes than those who did not. Conclusions: Our study identified several independent prognostic factors that might help determine the appropriate counseling patients following surgical treatment. D2 surgery alone was inadequate to achieve long-term survival. As the only correctable independent prognostic factor, postoperative adjuvant chemotherapy should be recommended for eligible patients with stage III gastric cancer.

Abstract
BACKGROUND Determining the survival outcome for gastric cancer patients with metastases to more than 15 regional lymph nodes is difficult. This study aims to develop a lymph node metastatic ratio (LNR)-based prognostic model to predict the survival outcome after D2 surgery in such patient groups. METHODS Our study retrospectively enrolled 139 gastric cancer patients with metastases to more than 15 regional lymph nodes who underwent D2 surgery between 2007 and 2014. Clinicopathologic variables to predict overall survival (OS) using multivariate Cox regression were selected to create a prognostic model. RESULTS The prognostic model for predicting OS was developed based on five independent factors, namely, T-classification (T2 or T3 vs. T4), LNR (<0.80 vs. ≥0.80), carcinoembryonic antigen level (<5 vs. ≥5 ng/ml), Eastern Cooperative Oncology Group performance scale (scale 0-1 vs. ≥2), and adjuvant chemotherapy (yes vs. no). Using the prognostic score, patients were stratified into good, intermediate, and poor prognostic groups. The median OS in the good, intermediate, and poor prognostic risk groups was 32.0 months (95% confidence interval [CI]: 22.3-41.7), 12.4 months (95% CI: 8.5-16.3), and 5.4 months (95% CI: 2.1-8.7), respectively. The c-index of the prognostic model was 0.79 (95% CI: 0.71-0.87). CONCLUSION This study developed an accurate LNR-based prognostic model for predicting the survival outcome after D2 surgery in gastric cancer patients with metastasis to more than 15 regional lymph nodes. This model might assist clinicians in prognostic stratification of such patients and convince eligible patients to receive adjuvant chemotherapy.

Abstract
BACKGROUND Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. METHODS A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. RESULTS The percentages of patient populations aged <40 years, 40-49 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years were 9.7%, 17.7%, 27.8%, 22.1%, 16.9%, and 5.7%, respectively. The median follow-up period was 38.9 months (range, 22.8-60.4 months) and the overall, cancer-specific, and noncancer-specific mortality rates were 26.0%, 17.6%, and 8.5%, respectively. The overall mortality rate of patients in different age groups were 18.5%, 21.1%, 22.0%, 25.3%, 35.3%, and 49.0%, respectively. Compared to patients aged <40 years, more significant decrease in long-term survival were observed in aging patients. Multivariate analysis showed higher postoperative short-term mortality rates in patients older than 70 years, and the adjusted odds ratio of mortality risk ranged from 1.47 to 1.74 and 2.26 to 3.03 in patients aged 70-79 years and ≥80 years, respectively, compared to those aged <40 years. CONCLUSION Aging was a negative prognostic factor of survival outcome in solid cancer patients receiving curative surgery. After adjustment of other clinicopathologic factors, the influence of age on survival outcome was less apparent in the elderly.

Abstract
Background and Objectives: The standard treatment for carcinomas of the ampulla of Vater (CAV) is surgical resection. Nevertheless, recurrence is observed in half of the patients within five years after cancer surgery. In this study, we aimed to identify predictive factors and develop a nomogram capable of predicting the risk of recurrence in post-resection CAV patients. Methods: Our study cohort was composed of two hundred and twelve patients who had undergone radical surgery for CAV between 2000 and 2012. Clinicopathological variables predictive of recurrence were identified using univariate analysis. A Cox proportional hazards model was used to select the predictive factors used for the nomogram. Results: The 5-year overall survival, cancer-specific survival and disease-free survival rates were 44.3%, 51.1%, and 42.8%, respectively. The five most predictive variables for tumor recurrence were chosen to develop the nomogram. The nomogram had a highly predictive performance, with a bootstrap-corrected concordance index of 0.72 (95% confidence interval, 0.67-0.79). Furthermore, the performance of the nomogram was found to be better than the American Joint Committee on Cancer (AJCC) staging system due to better homogeneity, higher ability of discrimination and higher risk stratification of the model. Conclusions: We developed a predictive nomogram for estimating tumor relapse probability in CAV patients after radical surgery. This nomogram might be more informative than the AJCC staging system and may allow for better estimation of the probability of relapse after surgical resections.

Abstract
In 2009, a new citrus viral disease caused by Citrus yellow vein clearing virus (CYVCV) was discovered in China. To more effectively monitor the presence of CYVCV, a survey was conducted in 166 citrus orchards from 11 major citrus-growing provinces in China from May 2014 to April 2016. In all, 458 of a total of 2,350 citrus samples tested positive for CYVCV, demonstrating that the virus is widely distributed in China. In this study, the complete genome sequences of 19 CYVCV isolates from different provinces and hosts were sequenced and characterized. Comparisons of the whole-genome sequences of these 19 CYVCV isolates as well as 4 isolates previously reported from around the world revealed that the sequence identity ranged from 97.1 to 99.8%, indicating that there is a very low level of sequence heterogeneity among CYVCV isolates of different geographic origins and hosts. Phylogenetic analysis of these 23 genomic sequences suggested that all of the isolates from China were clustered into the same clade, clearly apart from the CYVCV isolates from Turkey and Pakistan. To our knowledge, this is the first extensive survey conducted in China for CYVCV incidence.

Abstract
BACKGROUND AND AIM Epstein-Barr virus (EBV) is suggested to actively utilize its ebv-microRNAs (miRNAs) to manipulate viral and cellular functions during neoplasia transformation. A systemic profiling of ebv-miRNAs expressed in EBV-associated gastric carcinoma (EBVa GC) helps understand its epigenetic regulation of carcinogenesis. METHODS A total of 1039 patients with gastric cancer were screened for EBVa GC using EBV-encoded RNAs in situ hybridization. A comprehensive profiling of ebv-miRNAs expressed in EBVa GC was constructed using stem-loop quantitative polymerase chain reaction. Functional assay of specific ebv-miRNA was conducted. Expression of epithelial-to-mesenchymal transition (EMT) markers among EBVa GC and non-EBVa GC was compared. RESULTS The prevalence of EBVa GC was 5.0% (52 out of 1039) in our series. The most abundant ebv-miRNAs of EBVa GC were Bart4, followed by Bart11, Bart2, Bart6, Bart9, and Bart18, in the decreasing order. Of them, Bart9 exhibited the same seed sequence as to hsa miR-200a and miR-141. Expression of E-cadherin of EBV-positive SNU-719 was increased after BART9 knockdown. Depleting endogenous Bart9 of SNU-719 induced a surged expression of miR-200a and miR-141, accompanied by decreased proliferative and invasive ability. Expression of mesenchymal markers in EBVa GC was increased compared with those of non-EBVa GC, albeit the two cohorts exhibited a comparable long-term survival. CONCLUSIONS We constructed a comprehensive profiling of ebv-miRNAs in EBVa GC. BART9 plays an important role during carcinogenesis through EMT. Inherent mesenchymal phenotype of EBVa GC represents a unique virus-induced morphology and microenvironment rather than being able to predict the prognosis.

Abstract
BACKGROUND The present study assessed the impact of the retrieval of >25 lymph nodes (LNs) on the survival outcome of patients with advanced gastric cancer after curative-intent gastrectomy. PATIENTS AND METHODS A total of 5,386 patients who had undergone curative gastrectomy for gastric cancer from 1994 to 2011 were enrolled. The clinicopathological parameters and overall survival (OS) were analyzed according to the number of LNs examined (≤15, n = 916; 16-25, n = 1,458; and >25, n = 3,012). RESULTS The percentage of patients with >25 LNs retrieved increased from 1994 to 2011. Patients in the LN >25 group were more likely to have undergone total gastrectomy and to have a larger tumor size, poorer tumor differentiation, and advanced T and N stages. Hospital mortality among the LN ≤15, LN 16-25, and LN >25 groups was 6.1%, 2.7%, and 1.7%, respectively (p < .0001). The LN >25 group consistently exhibited the most favorable OS, in particular, with stage II disease (p = .011) when OS was stratified according to tumor stage. Similarly, the LN >25 group had significantly better OS in all nodal stages (from N1 to N3b). The discrimination power of the lymph node ratio (LNR) for the LN ≤15, LN 16-25, and LN >25 groups was 483, 766, and 1,560, respectively. Multivariate analysis demonstrated that the LNR was the most important prognostic factor in the LN >25 group. CONCLUSION Retrieving more than 25 lymph nodes during curative-intent gastrectomy substantially improved survival and survival stratification of advanced gastric cancer without compromising patient safety. The Oncologist 2017;22:97-106Implications for Practice: D2 lymph node (LN) dissection is currently the standard of surgical management of gastric cancer, which is rarely audited by a third party. The present study, one of the largest surgical series worldwide, has shown that the traditionally recognized retrieval of ≥16 LNs during curative-intent gastrectomy might not be adequate in regions in which locally advanced gastric cancers predominate. The presented data show that retrieval of >25 LNs, which more greatly mimics D2 dissection, improves long-term outcomes and survival stratification without compromising patient safety.

Abstract
BACKGROUND Approximately, 50% of all gastric cancer patients are aged >70 y. Although curative surgery is the treatment of choice, many geriatric patients die of surgical complications. Therefore, we aimed to evaluate the impact of radical surgery on the survival outcome of geriatric patients with resectable gastric cancers. METHODS About 488 patients diagnosed with resectable gastric cancers, aged ≥70 y, between January 2007 and December 2012 at Chang Gung Memorial Hospital (CGMH) Linkou branch were included in this study. Using univariate and multivariate analyses, possible prognostic variables for survival outcome were assessed in 445 patients (91.2%) treated with radical surgery (operation [OP] group) and 43 (8.8%) receiving conservative treatment (non-OP group). The impact of radical surgery on survival outcomes was evaluated according to CGMH scores. RESULTS On multivariate analysis, surgical resection with subtotal gastrectomy and CGMH score were the only independent prognostic factors for both overall and cancer-specific survival. The median survival time was 43 mo for the entire cohort. The OP group had significantly better survival outcome than the non-OP group (median survival, 50.3 versus 16.2 mo, P < 0.001). The median survival times for patients with CGMH scores ≤20 were 64.1 and 20.0 mo (P < 0.002) and those for patients with CGMH scores >20 were 13.8 and 10.4 mo (P = 0.18) in the OP and non-OP groups, respectively. CONCLUSIONS Surgical resection and CGMH score are independent prognostic factors for overall and cancer-specific survival; the CGMH score might be a prognostic indicator of surgical outcome in geriatric patients with resectable gastric cancers.

Abstract
Local recurrence frequently occurs in patients with pancreatic cancer after intended curative resections. However, no treatment strategies have been established for isolated local recurrence. Several series have demonstrated a survival benefit for reoperation in selected pancreatic recurrence cases. This study compares the difference in overall survival (OS) between surgery and nonsurgery groups in recurrent pancreatic cancer.All patients from 1990 to 2014 with recurrent pancreatic cancer who underwent curative resections were investigated and retrospectively reviewed. Clinicopathological features and OS were compared.A total of 332 patients were recruited in this series. The majority had histologically pancreatic adenocarcinoma (289 patients, 87.0%). Fourteen of 332 patients (4.2%) with recurrent pancreatic cancer received subsequent resection. Most of these patients underwent curative surgery (R0 resection, 13 patients, 92.9%), and only 1 patient (7.1%) had microscopic residual tumor (R1 resection). Disease-free survival (DFS), OS, and postrecurrence survival (PRS) were all significantly longer in the surgery group (DFS 10.6 vs 6.1 months, P = 0.044; OS 57.8 vs 14.0 months, P < 0.001; PRS 14.1 vs 6.0 months, P < 0.001). The median survival times were comparable in patients with recurrent pancreatic adenocarcinoma who received surgery and those who did not (DFS 10.6 vs 6.1 months, P = 0.226; OS 23.7 vs 14.0 months, P = 0.074; PRS 8.9 vs 5.8 months, P = 0.183). However, the OS and PRS were superior in the patients who did not display adenocarcinoma histologically but underwent operation for recurrence (OS 97.2 vs 16.9 months, P = 0.016; PRS 65.7 vs 6.9 months, P = 0.010). Notably, DFS levels were similar (16.0 vs 7.0 months, P = 0.265).Surgery can feasibly and safely provide survival benefits in selective recurrent pancreatic cancer. In patients who are histologically negative for adenocarcinoma, survival is prolonged when the operation is performed with R0 resection. Patients with isolated recurrent pancreatic adenocarcinoma need multidisciplinary therapy. In addition to operation, chemoradiotherapy and intraoperative radiotherapy may also be considered; their roles should be further investigated.

Abstract
Purpose: Patients with comorbidities are more likely to experience treatment-related toxicities and death. Our aim was to examine the effect of comorbidity on postoperative survival outcomes in patients with solid cancers. Methods: In total, 37,288 patients who underwent potentially curative operations for solid cancers at four affiliated hospitals of the Chang Gung Memorial Hospital, between 2007 and 2012, were stratified according to the Charlson Comorbidity Index (CCI) for postoperative survival analysis. Multivariate Cox regression was used to adjust hazard ratios of survival outcomes among different CCI subgroups. Results: A significantly greater proportion of patients with comorbidities presented with poorer clinicopathological characteristics compared to those without. After cancer surgery, 26% of patients died after a median follow-up duration of 38.9 months. Overall mortality rates of patients with CCI scores of 0, 1, 2, 3, 4, and 5-8 were 22.9%, 29.5%, 38.2%, 43.2%, 50.2%, and 56.4%, respectively. After adjusting for other clinicopathological factors, patients with increasing CCI scores were associated with significantly reduced overall and noncancer-specific survival rates, while only patients with CCI scores of >2 were associated with higher cancer-specific mortality rates. Conclusions: Patients with increasing numbers of comorbidities were associated with reduced postoperative survival outcomes. Patients with multiple comorbidities were most vulnerable to both cancer- and noncancer-specific deaths in the first 6 months after cancer surgery. Our results suggest that for both the patient and clinician, it should be taken into consideration about cancer surgery when dealing with multiple comorbidities.

Abstract
Context: Appropriate selection of aging patient who fit for cancer surgery is an art-of-state. Objectives: This study aimed to identify predictive factors pertinent to 3-month postoperative mortality in geriatric cancer patients. Methods: A total of 8,425 patients over 70 years old with solid cancer received radical surgery between 2007 and 2012 at four affiliated hospitals of the Chang Gung Memorial Hospital were included. The clinical variables of patients who died within 3 months post-surgery were analyzed retrospectively. Recursive partitioning analysis (RPA) was performed by randomly selecting 50% of the patients (testing set) to identify specific groups of patients with the lowest and highest probability of 3-month postoperative mortality. The remaining 50% were used as validation set of the model. Results: Patients' gender, Eastern Cooperative Oncology Group performance (ECOG scale), Charlson comorbidity index (CCI), American Society of Anesthesiologist physical status, age, tumor staging, and mode of admission were independent variables that predicted 3-month postoperative mortality. The RPA model identified patients with an ECOG scale of 0-2, localized tumor stage, and a CCI of 0-2 as having the lowest probability of 3-month postoperative mortality (1.1% and 1.3% in the testing set and validation set, respectively). Conversely, an ECOG scale of 3-4 and a CCI >2 were associated with the highest probability of 3-month postoperative mortality (55.2% and 47.8% in the testing set and validation set, respectively). Conclusion: We identified ECOG scale and CCI score were the two most influencing factors that determined 3-month postoperative mortality in geriatric cancer patients.

Abstract
Patients with carcinoma of the ampulla of Vater (CAV) have better outcomes among periampullary malignancies. However, little is known about the metastatic lymph node ratio (LNR) as a prognostic factor for resectable CAV. We retrospectively reviewed our CAV patients undergoing curative surgery and analyzed their prognostic factors.A total of 212 CAV patients who received radical surgery at Chang Gung Memorial Hospital, Linkou, between 2000 and 2010 were admitted in this study. The lymph node ratio was defined as the number of metastatic lymph nodes (LNs) divided by the total number of LNs removed. The patients' demographic data, comorbidities, operation type, and tumor features were analyzed retrospectively for survival prediction of patients.The median age of the patients was 62 years, and 57% of the patients were men. The surgical procedure was standard pancreaticoduodenectomy and pylorus-preserving pancreaticoduodenectomy in 53% and 47% of the patients, respectively. The median follow-up duration was 32.6 months, and 50% of the patients had died by the end of the study. The median overall survival time (OS) and disease-free survival time (DFS) were 65.8 and 33.7 months, respectively. In multivariate analysis, patients with a metastatic LNR >0.056 had a significantly poor prognosis in both OS and DFS.A metastatic LNR >0.056 predicted a poor DFS and OS in CAV patients after radical surgery. Greater awareness on the impact of metastatic LNR may help clinicians provide appropriate adjuvant treatment for high-risk CAV patients.

Abstract
In this study, we identified myogenic regulatory factors (MRFs) and analyzed the correlation between MRFs and meat quality in rainbow trout. The MyoD1a and MyoD1b genes were cloned from rainbow trout using a homology cloning method. Introns 1 and 2 in the MyoD1a and MyoD1b genes were cloned and submitted to GenBank (accession Nos. FJ623462 and FJ793566). Polymorphisms of MyoD1a and MyoD1b genes were analyzed using single-strand conformation polymorphism and sequencing, respectively. Two single nucleotide polymorphisms were detected in the MyoD1 gene, located at 129G→A in exon 1 and 37 G→A in exon 2. The 37 G→A mutation in exon 2 induced the R185K amino acid change in the polypeptide chain. Seven single nucleotide polymorphisms in the MyoD2 gene were detected, including 218T→C, 224T→C, 242A→C, 246T→A, 248T→C, 305T→C, and 329C→T. The 246T→A mutation in exon 1 induced the R83K change in the polypeptide chain. In the S3 fragment, meat quality traits of genotypes AA and AB significantly differed from those of genotype BB (P < 0.05). In the S5 fragment, meat quality traits of the genotypes AA and AC were significantly different from the genotypes BB and BC (P < 0.05). These results indicate that the MyoD1a and MyoD1b genes have an important influence on meat quality or were linked to the major genes in these strains. These genes can be used to control muscle fiber traits in rainbow trout, and the mutations in the S3 and S5 fragments can be used as molecular markers for selecting rainbow trout with better meat quality traits.

Abstract
PURPOSE Shear wave elastography (SWE) is a new technique which provides quantitative assessment of soft tissue stiffness. The aim of this study was to assess the reliability of SWE stiffness measurements and its usefulness in evaluating post-irradiation neck fibrosis. MATERIALS AND METHODS 50 subjects (25 patients with previous radiotherapy to the neck and 25 sex and age-matched controls) were recruited for comparison of SWE stiffness measurements (Aixplorer, Supersonic Imagine). 30 subjects (16 healthy individuals and 14 post-irradiated patients) were recruited for a reliability study of SWE stiffness measurements. SWE stiffness measurements of the sternocleidomastoid muscle and the overlying subcutaneous tissues of the neck were made. The cross-sectional area and thickness of the sternocleidomastoid muscle and the overlying subcutaneous tissue thickness of the neck were also measured. The post-irradiation duration of the patients was recorded. RESULTS The intraclass correlation coefficients for the intraoperator and interoperator reliability of deep and subcutaneous tissue SWE stiffness ranged from 0.90-0.99 and 0.77-0.94, respectively. The SWE stiffness measurements (mean +/- SD) of deep and subcutaneous tissues were significantly higher in the post-irradiated patients (64.6 ± 46.8 kPa and 63.9 ± 53.1 kPa, respectively) than the sex and age-matched controls (19.9 ± 7.8 kPa and 15.3 ± 8.37 respectively) (p < 0.001). The SWE stiffness increased with increasing post-irradiation therapy duration in the Kruskal Wallis test (p < 0.001) and correlated with muscle atrophy and subcutaneous tissue thinning (p < 0.01). CONCLUSION SWE is a reliable technique and may potentially be an objective and specific tool in quantifying deep and subcutaneous tissue stiffness, which in turn reflects the severity of neck fibrosis.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) is the most acceptable procedure in laparoscopic pancreatic surgery. Nevertheless, knowledge regarding patients at a high anesthetic risk during lengthy and technically demanding LDP is controversial. This study aims to assess the feasibility and safety of LDP in patients with high anesthetic risk. PATIENTS AND METHODS We conducted a prospective collection retrospective review of patients underwent LDP and open distal pancreatectomy (ODP) from January 2011 until December 2013. By the American Society of Anesthesiologists score, patients were divided into low- and high-risk patients. We compared the clinical, perioperative, and postoperative results in these patients. RESULTS The cohort included 77 patients: 20 underwent LDP, and 57 underwent ODP. There were 30 patients in the low-risk group and 47 patients in the high-risk group. In high-risk patients, LDP, compared with ODP, presented a shorter operating time (mean, 220.8±101.1 minutes versus 299.4±124.3 minutes; P=.038), less blood loss (409.3±569.9 mL versus 1083.1±1583.0 mL; P=.039), higher rate of spleen preservation (73.3% versus 43.8%, P=.037), and shorter length of postoperative hospital stay (LOS) (9.5±3.0 days versus 15.7±9.4 days; P=.044). CONCLUSIONS In conclusion, LDP provides early recovery and better cosmetic appearance. In high anesthetic risk patients, LDP shows less operative time, less perioperative blood loss, a higher rate of spleen preservation, slighter complication, and shorter LOS, which might explain why LDP is a feasible and effective procedure.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is challenging because of the limited ability of conventional endoscopic tools to achieve adequate traction. We have recently used a novel steerable grasper (SG; ANUBIS grasper, Karl Storz, Tüttlingen, Germany) with intuitive manipulating handles to lift up the mucosa. The aim of this study is to evaluate the efficacy of the assistance of the SG in a porcine acute model. MATERIALS AND METHODS A total of 36 gastric ESDs were performed in 12 swine (3 ESDs/pig), at the antrum, greater curvature of the gastric body, and cardia. Pigs were randomly assigned to the SG group (n = 6) or to the control group (n = 6). ESD steps included the following: scoring the area, submucosal injection, and precut and submucosal dissection with or without SG assistance. Outcomes measured were as follows: dissection time, dissection speed, size of specimen, completeness of dissection (all marks included in the specimen), en bloc dissection, and complications. RESULTS Overall mean dissection time was 18.6 ± 7.56 versus 29 ± 18.14 minutes (P = .032), and mean dissection speed was 94.74 ± 39.74 mm(2)/min versus 65.41 ± 39.5 mm(2)/min (P = .033) in the SG and control groups, respectively. Mean size of the specimen was 1451.4 ± 549.2 mm(2) in the SG group and 1615.3 ± 605.9 in the control group. Complete and en bloc dissections were achieved in all cases. One deep muscular injury occurred in the control group (gastric body). CONCLUSION The ANUBIS grasper is a user-friendly, effective, and safe tool to achieve adequate traction and exposure of the ESD plane in the pig model.

Abstract
The seventh edition of the American Joint Committee on Cancer (AJCC) TNM classification system for gastric cancer (GC) was established in 2009. We assessed the unmet medical needs of patients with the N3 classification of the seventh TNM staging system by comparing survival according to the extent of nodal involvement, with a particular focus on the cutoff points for the number of involved nodes in the N3 classification. We retrospectively reviewed 3178 patients with GC who were registered in the GC database of the Department of General Surgery at the Chang Gung Memorial Hospital between 1994 and 2010. Among them, 884 patients undergoing curative intent resection had N3 lymph node involvement. The clinicopathological features and surgical outcomes were compared among all patients with GC and between the N3a and N3b groups. N3b might impose GC patients with poor clinical outcome. We proposed a modified staging system, based on AJCC seventh edition, accordingly. T1-3N3 might be not simply categorized into stage IIIA as seventh AJCC suggested. Taking N3a and N3b into consideration, T1-3N3 might be further categorized into stage IIIB and IIIC, respectively, as we proposed, based on survival analysis. In addition, T4bN3bM0 is as dismal as M1 disease. In our proposed staging system, good discriminations between different stages are still maintained. The N3 category should be subclassified as N3a or N3b due to the survival differences. Furthermore, T1-3N3aM0 could be categorized as stage IIIB, T1-3N3bM0 could be categorized as stage IIIC, T4aN3bM0 could be categorized as stage IIID, and T4bN3bM0 might be regarded as stage IV as we proposed.

Abstract
Epstein-Barr virus-associated gastric carcinoma (EBVaGC) has distinct clinicopathological features. However, the prognostic factors remain unclear, particularly in UICC/AJCC stage I-III cancer. We retrospectively enrolled 1,020 patients with stage I-III gastric cancer that received radical gastrectomy with lymphadenectomy. Formalin-fixed, paraffin‑embedded surgical specimens were retrieved to construct tissue microarrays. EBV positivity was identified by in situ hybridization with EBV-encoded small RNA, and the histological classification was reviewed. Fifty-two cases of EBVaGC were identified, exhibiting a male predominance (p=0.003), a higher prevalence in stump cancer (p<0.001), and poorly differentiated carcinoma (p=0.010) compared with the controls. The survival analysis revealed no difference in survival between the EBVaGC cases and the EBV-negative cases (p=0.977). The multivariate analysis showed that EBVaGC cases with a tumor size >5 cm, non-lymphoepithelioma-like carcinoma (LELC), or a lymph node ratio >0.15 had a worse overall survival (hazard ratio 2.884, 12.178 and 19.352; p=0.027, 0.005 and <0.0001, respectively). The depth of tumor invasion and the number of lymph node metastases did not reach statistical significance (p=0.834 and 0.833, respectively). These prognostic factors, tumor size, LELC classification and lymph node ratio, may reflect a unique type of carcinogenesis of EBVaGC and may be considered when selecting high-risk patients for adjuvant treatment.
