ABSTRACT
BACKGROUND: There remain concerns about the safety and functional benefit of laparoscopic pylorus-preserving gastrectomy (LPPG) compared with laparoscopic distal gastrectomy (LDG). This study evaluated short-term outcomes of a randomized clinical trial (RCT) comparing LPPG with LDG for gastric cancer. METHODS: The Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS)-04 trial was an investigator-initiated, open-label, parallel-assigned, superiority, multicentre RCT in Korea. Patients with cT1N0M0 cancer located in the middle third of the stomach at least 5 cm from the pylorus were randomized to undergo LPPG or LDG. Participants, care givers and those assessing the outcomes were not blinded to group assignment. Outcomes were 30-day postoperative morbidity rate and death at 90 days. RESULTS: Some 256 patients from nine institutions were randomized (LPPG 129 patients, LDG 127 patients) between July 2015 and July 2017 and outcomes for 253 patients were analysed. Postoperative complications within 30 days were seen in 19.3 and 15.5 per cent in the LPPG and LDG groups respectively (P = 0·419). Postoperative pyloric stenosis was observed in nine (7.2 per cent) and two (1·5 per cent) patients in the LPPG and LDG groups (P = 0·026) respectively. In multivariable analysis higher BMI was a risk factor for postoperative complications (odds ratio 1·17, 95 per cent c.i. 1·04 to 1·32; P = 0·011). Death at 90 days was zero in both groups. CONCLUSION: Postoperative complications and mortality was comparable in patients undergoing LPPG and LDG. Registration number: NCT02595086 (http://www.clinicaltrials.gov).

This study examined how patients with cancer estimate caregiver burden (CB) and the association between their underestimation of CB and their caregivers' self-ratings of their quality of life (CQOLC-K; Korean version of the Caregiver Quality of Life Index-Cancer), depression and anxiety (Korean version of the Hospital Anxiety and Depression Scale). Participants consisted of 990 patient-caregiver dyads recruited from a nationwide cross-sectional survey conducted in South Korea. Medical baseline data were retrieved from the hospital information systems of the participating centres. The patients with cancer who underestimated CB ranged from 18.62% (for physical CB) to 23.33% (for social CB). They had less advanced cancer, a lower income, were the caregiver's spouse, reported higher levels of family avoidance of communication about cancer, and had female caregivers. The patients' underestimation of CB was significantly related to lower CQoL and higher levels of caregiver depression and anxiety. The current study provides empirical evidence for the link between the underestimation of CB by patients with cancer and compromised caregiving experiences of cancer caregivers. Open family communication about cancer was discussed as one of several practical strategies for decreasing patients' underestimation of CB.

BACKGROUND: We have developed the Atopic Dermatitis Symptom Score (ADSS) by which patients or parents can easily assess and record AD symptoms on a daily basis in a smartphone application. The aim of this study was to evaluate the reliability and validity of the ADSS. METHODS: We enrolled 307 children and adolescents with AD. Parents or caregivers were asked to record daily symptoms of the patients (itching, sleep disturbance, erythema, dryness, oozing, and edema) using a scale of 0-4. Statistical analyses consisted of the test-retest reliability, concurrent validity, minimal clinically important difference (MCID), responsiveness, floor or ceiling effects, and screening accuracy. Receiver-operating characteristic analyses were conducted to evaluate the ADSS cutoff point for predicting severe AD (SCORing AD [SCORAD] ≥40). RESULTS: Test-retest reliability between daytime and night-time ADSS was good (intraclass correlation coefficient, 0.82 [95% CI: 0.70-0.90]). An increase in ADSS was significantly associated with an increase in SCORAD (r = 0.64, P < .0001) (concurrent validity). The MCID was 4.1 points for the ADSS. There was a significant association between changes in ADSS and SCORAD (r = 0.56, P < .0001), indicating good responsiveness. At the optimal ADSS cutoff value of 7.0, sensitivity, specificity, and positive and negative predictive values were 88.4%, 78.6%, 21.1%, and 99.1%, respectively (screening accuracy). CONCLUSIONS: The ADSS can be a useful tool for self-assessment of skin symptoms in children with AD.

BACKGROUND: Although live-attenuated varicella-zoster virus (VZV) vaccines have been proven to be safe and effective in preventing varicella and real-word evidence shows routine childhood immunization programs are effective in dramatically reducing varicella associated morbidity and mortality, varicella vaccine is not included in the National Immunization Program (NIP) in Hungary. The purpose of this study was to evaluate the clinical and economic burden associated with varicella in Hungary. METHODS: This was a multicenter, retrospective, chart review study of patients aged 1-12 years with a primary varicella diagnosis between 2011 and 2015. Healthcare resource utilization (HCRU) associated with varicella, unit costs, and work loss were used to estimate direct and indirect costs. All costs are presented in 2015 HUF / Euros (). RESULTS: 156 children with varicella were included (75 outpatients, 81 inpatients), with a mean age of 4.4 (SD: 2.0) and 3.7 (SD: 2.1) years, respectively. One or more complications were reported by 12.0% of outpatients and 92.6% of inpatients, the most common being dehydration, skin and soft tissue infections, pneumonia, keratoconjunctivitis, and cerebellitis. HCRU estimates included use of over-the-counter (OTC) medications (96.0% outpatients, 53.1% inpatients), prescription medications (9.3% outpatients, 70.4% inpatients), tests/procedures (4.0% outpatients, 97.5% inpatients), and consultation with allied health professionals (2.7% outpatients, 30.9% inpatients). The average duration of hospital stay (inpatients) was 3.6 (95% CI: 3.2, 4.1) days. The total combined direct and indirect cost per varicella case was 228,146.7 Hungarian Forint (HUF)/ 736.0 for inpatients and 49,790.6 HUF/ 106.6 for outpatients. The overall annual cost of varicella in Hungary for children aged <15 years in 2015 was estimated at 1,903,332,524.3 HUF/ 6,139,980.4. CONCLUSION: Varicella is associated with substantial clinical burden in Hungary, resulting in the utilization of a significant amount of healthcare resources. These results support the need for routine vaccination of all healthy children to reduce the varicella-associated disease burden.

PurposeThe double Maddox-rod test (DMRT) and Lancaster red-green test (LRGT) are the most widely used tests worldwide to assess subjective ocular torsion. However, these tests require equipment and the quantified results of ocular torsion are only provided in rough values. Here we developed a novel computerized torsion test (CTT) for individual assessment of subjective ocular torsion and validated the reliability and accuracy of the test compared with those of the DMRT and LRGT.MethodsA total of 30 patients with cyclovertical strabismus and 30 controls were recruited. The CTT was designed using Microsoft Office PowerPoint. Subjects wore red-green filter spectacles and viewed gradually tilted red and cyan lines on an LCD monitor and pressed the keyboard to go through the slides, until both lines seemed parallel. All subjects underwent the CTT, DMRT, and LRGT. Intraclass correlation coefficients and Bland-Altman plots were analyzed to assess the acceptability of the CTT compared with that of the DMRT.ResultsBoth the DMRT and CTT showed no significant test-retest differences in the strabismus and control groups. The DMRT and CTT results demonstrated an acceptable agreement. The reliability of the CTT was better than that of the DMRT. The LRGT showed low sensitivity for the detection of ocular torsion compared with the DMRT (40.0%) and CTT (39.1%).ConclusionOur results suggest that the assessment of subjective ocular torsion using the CTT based on PowerPoint software is simple, reproducible, and accurate and can be applied in clinical practice.

BACKGROUND: Prognostic models from Korea and Italy have been developed that predict overall survival and cancer recurrence respectively after radical gastrectomy for gastric cancer. The aim of this study was to validate the two models in independent patient cohorts, and to evaluate which factors may explain differences in prognosis between Korean and Italian patients with gastric cancer. METHODS: Patients who underwent radical gastrectomy for gastric cancer between January 2000 and December 2004 at Seoul National University Hospital and at eight centres in Italy were included. Discrimination of the models was tested with receiver operating characteristic (ROC) curves and calculation of area under the curve (AUC). Calibration was evaluated by plotting actual survival probability against predicted survival probability for the Korean nomogram, and actual against predicted risk of recurrence for the Italian score. RESULTS: Some 2867 and 940 patients from Korea and Italy respectively were included. The Korean nomogram achieved good discrimination in the Italian cohort (AUC 0·80, 95 per cent c.i. 0·77 to 0·83), and the Italian model performed well in the Korean cohort (AUC 0·87, 0·85 to 0·89). The Korean nomogram also achieved good calibration, but this was not seen for the Italian model. Multivariable analyses confirmed that Italian ethnicity was an independent risk factor for cancer recurrence (odds ratio (OR) 1·72, 1·31 to 2·25; P < 0·001), but not for overall survival (OR 1·20, 0·95 to 1·53; P = 0·130). CONCLUSION: Both prognostic models performed fairly well in independent patient cohorts. Differences in recurrence rates of gastric cancer may be partially explained by ethnicity.

BACKGROUND/OBJECTIVES: There has been an increasing global recognition of the need for effective strategies to prevent and control childhood obesity. In this study, we aimed to identify the effectiveness of an obesity prevention program focused on motivating environments in school. SUBJECTS/METHODS: In this school-based, prospective, quasi-experimental study, we enrolled three elementary (fourth graders) and two middle (seventh graders) schools located in Chungju, Korea. We assigned three of the schools to the intervention group and two schools to the control group. The intervention group received 1 year of environmental intervention. Diet- and exercise-related educational video content was provided by internet protocol television services during rest time, and various design materials were painted along the school staircase and hallway to encourage physical activities. Overweight and obese students were recommended to join the summer vacation obesity care program. RESULTS: The final number of total participants was 768 (control 350 and intervention 418). After 1 year of follow-up, there was no significant difference in the overweight/obesity incidence rates and remission rates between the two groups. However, the intervention group showed a greater decrease in the body mass index (BMI) z-score (-0.11 (95% confidence interval (CI) -0.16 to -0.06), P<0.001), increase in height (1.1 cm (95% CI 0.8 to 1.4), P<0.001), reduction of body fat, and increase in muscle mass compared with the control group. In addition, blood pressure (BP) was significantly reduced, and significant improvement in physical fitness followed. In subgroup analysis, students of normal weight, boys and younger participants showed the most beneficial results in weight-related outcomes. In addition, the BP reduction was more pronounced in the higher BMI group, boys and older children. CONCLUSIONS: A simple environmental intervention could effectively influence children. By adding to previously studied strategies, we can develop a more effective obesity prevention program for children.

OBJECTIVES: Our aim was to investigate the association between the triglycerides/glucose index (TyG index) and the homeostasis model assessment-estimated insulin resistance (HOMA-IR) in the prediction of insulin resistance (IR) among adolescents. METHODS: We conducted a cross-sectional study among 221 Korean adolescents (168 males and 53 females aged 9-13 years) from May to June 2014 in Chung-ju city. The TyG index was calculated as ln [triglycerides (mg dl-1) × fasting glucose (mg dl-1)/2]. IR was defined using HOMA-IR >95th percentile for age and sex. RESULTS: In the IR group, weight, body mass index (BMI), waist circumference, body fat, fasting insulin, fasting plasma glucose, triglyceride levels and triglycerides/high-density lipoprotein cholesterol (TG/HDL-C) were significantly higher than that in the non-IR group. The TG index was significantly different between the IR group (n=22) and non-IR group (n=199), at 8.43±0.45 and 8.05±0.41, respectively (P<0.001). The TyG index was well correlated with HOMA-IR (r=0.41; P<0.001) and showed a strong positive association with TG/HDL-C (r=0.84; P<0.001). The cut-off of the TyG index for diagnosis of insulin resistance was 8.18. CONCLUSIONS: The TyG index is a simple, cost-effective surrogate marker of insulin resistance among adolescents compared with HOMA-IR.

AIMS: Robotic gastrectomy for gastric cancer has been proven to be a feasible and safe minimally invasive procedure. However, our previous multicenter prospective study indicated that robotic gastrectomy is not superior to laparoscopic gastrectomy. This study aimed to identify which subgroups of patients would benefit from robotic gastrectomy rather than from conventional laparoscopic gastrectomy. METHODS: A prospective multicenter comparative study comparing laparoscopic and robotic gastrectomy was previously conducted. We divided the patients into subgroups according to obesity, type of gastrectomy performed, and extent of lymph node dissection. Surgical outcomes were compared between the robotic and laparoscopic groups in each subgroup. RESULTS: A total of 434 patients were enrolled into the robotic (n = 223) and laparoscopic (n = 211) surgery groups. According to obesity and gastrectomy type, there was no difference in the estimated blood loss (EBL), number of retrieved lymph nodes, complication rate, open conversion rate, and the length of hospital stay between the robotic and laparoscopic groups. According to the extent of lymph node dissection, the robotic group showed a significantly lower EBL than did the laparoscopic group after D2 dissection (P = 0.021), while there was no difference in EBL in patients that did not undergo D2 dissection (P = 0.365). CONCLUSION: Patients with gastric cancer undergoing D2 lymph node dissection can benefit from less blood loss when a robotic surgery system is used.

AIM: To investigate the magnetic resonance imaging (MRI) findings of spinal arteriovenous fistulas (AVFs) to predict their locations and types. MATERIALS AND METHODS: Patients who underwent spinal angiography for suspected spinal AVF between April 2003 and April 2013 were enrolled. Spine MRI images were analysed by two radiologists in consensus focusing on the distribution patterns of flow void pial vessels (FVPVs): longitudinal distribution pattern along the spinal level (even or uneven, with description of the most crowded level in uneven cases) and axial distribution pattern in relation to the cord (ventral, dorsal, or co-dominance). Spinal angiography served as the reference standard for the locations and types of fistulas. RESULTS: Thirty-two patients (M:F=24:8, mean age, 53 years; range, 2-74 years) were included. There were 18 patients with spinal dural AVFs (SDAVFs), seven with perimedullary AVFs, four with epidural AVFs, and three diagnosed as normal. In 12 of 15 longitudinally uneven AVFs, the most crowded levels of FVPVs corresponded to the true fistulous levels within two-level differences. While dorsal dominance was predominant in SDAVFs (13/18), ventral dominance was predominant in perimedullary AVFs (5/7; p<0.01). CONCLUSION: Fistulous levels may be predicted to be within two levels of the most crowded levels of FVPVs. The dorsal dominance pattern of FVPVs favours SDAVFs, whereas ventral dominance suggests perimedullary AVFs.

OBJECTIVE: To investigate the incidence of ethambutol (EMB) induced optic neuropathy prescribed at a relatively low dose of ≤ 15 mg/kg/day for the treatment of tuberculosis (TB) or Mycobacterium avium complex (MAC) lung disease. DESIGN: Patients diagnosed with TB or MAC lung disease received multidrug regimens including EMB at a single institution from August 2003 to July 2009. Visual monitoring was performed at baseline and at regular follow-up. The incidence of EMB-induced visual disturbances was evaluated. RESULTS: Of the 415 patients included in the study, three (0.7%) developed toxic optic neuropathy over the 6-year period. Of the 289 patients prescribed a dose of ≤ 15 mg/kg/day EMB, only one (0.3%) developed toxic optic neuropathy. CONCLUSIONS: The incidence of EMB-induced optic neuropathy among Koreans is estimated to be 0.7%, and can be reduced with lower doses of EMB.

AIM: To determine whether preadipocyte factor 1 could be a predictive marker for the development of diabetes in people without diabetes at baseline. METHODS: We conducted a population-based, nested case-control study of individuals who progressed to diabetes (n = 43) or prediabetes (n = 345) and control participants matched on age, sex and fasting plasma glucose concentration, who maintained normal glucose tolerance (n = 389) during a 4-year follow-up using data from the Chungju Metabolic disease Cohort Study. Circulating levels of preadipocyte factor 1 were measured using an enzyme-linked immunosorbent assay. RESULTS: Baseline serum preadipocyte factor 1 levels showed a stepwise decrease across the glucose tolerance status groups at follow-up (normal glucose tolerance: 10.02 ± 3.02 ng/ml; prediabetes: 9.48 ± 3.35 ng/ml; diabetes: 8.66 ± 3.29 ng/ml; P for trend, 0.0151). Individuals whose fasting plasma glucose level had increased or whose homeostasis model assessment of ß-cell function had decreased at follow-up showed significantly lower levels of preadipocyte factor 1 compared with their control group counterparts. After adjusting for age, BMI, fasting plasma glucose, serum insulin levels, systolic blood pressure and triglycerides, the incidence of diabetes was nearly threefold higher in the lowest vs. the upper three quartiles of circulating preadipocyte factor 1 (relative risk 2.794; 95% CI 1.188-6.571; P = 0.0185). Notably, these findings were significant in women but not in men. CONCLUSIONS: Levels of circulating preadipocyte factor 1 may be a useful biomarker for identifying women at high risk of developing diabetes.

We aimed to investigate whether the effect of problematic alcohol drinking on hypertension differed according to metabolic health statuses. Male participants from the fifth Korea National Health and Nutrition Examination Survey were recruited. Problematic alcohol drinkers were designated as subjects with heavy drinking (⩾30 g per day), binge drinking (⩾7 glasses per day) or a high alcohol use disorders identification test score (⩾20). Metabolically obese status was defined as having ⩾1 or ⩾2 components of the diagnostic criteria for metabolic syndrome, excluding the blood pressure component. Because the prevalence of problematic alcohol drinking and the prevalence of hypertension largely differed by age groups, separate analyses were performed for the two age groups (<50 and ⩾50 years). Among a total of 6329 subjects, 37.04% had hypertension. In the younger age group, subjects with problematic alcohol drinking demonstrated a higher prevalence of hypertension in both nonobese and obese individuals compared with subjects who were nonobese and who were not problematic alcohol drinkers. Of note, problematic alcohol drinking increased the risk of having hypertension â¼3 times in young nonobese individuals who demonstrated a metabolically obese phenotype compared with those who were metabolically healthy. However, metabolic health status did not have a significant impact on the risk for having hypertension in obese participants, regardless of their age groups. For the prevention of hypertension, avoidance of problematic alcohol drinking should be emphasized, especially in young subjects who show poor metabolic health status despite being nonobese.

BACKGROUND: In this study, we aimed to identify demographic and clinical variables that correlate with perceived information provision among cancer patients and determine the association of information provision with decisional conflict (DC). PATIENTS AND METHODS: We enrolled a total of 625 patients with cancer from two Korean hospitals in 2012. We used the European Organization for Research and Treatment of Cancer (EORTC) quality-of-life questionnaire (QLQ-INFO26) to assess patients' perception of the information received from their doctors and the Decisional Conflict Scale (DCS) to assess DC. To identify predictive sociodemographic and clinical variables for adequate information provision, backward selective logistic regression analyses were conducted. In addition, adjusted multivariate logistic regression analyses were carried out to identify clinically meaningful differences of perceived level of information subscales associated with high DC. RESULTS: More than half of patients with cancer showed insufficient satisfaction with medical information about disease (56%), treatment (73%), other services (83%), and global score (80%). In multiple logistic regression analyses, lower income and education, female, unmarried status, type of cancer with good prognosis, and early stage of treatment process were associated with patients' perception of inadequate information provision. In addition, Information about the medical tests with high DCS values clarity [adjusted odds ratio (aOR), 0.54; 95% confidence interval (CI) 0.30-0.97] and support (aOR, 0.53; 95% CI 0.33-0.85) showed negative significance. For inadequate information perception about treatments and other services, all 5 DCS scales (uncertainty, informed, values clarity, support, and effective decision) were negatively related. Global score of inadequate information provision also showed negative association with high DCS effective decision (aOR, 0.43; 95% CI 0.26-0.71) and DCS uncertainty (aOR, 0.46; 95% CI 0.27-0.77). CONCLUSION: This study found that inadequate levels of perceived information correlated with several demographic and clinical characteristics. In addition, sufficient perceived information levels may be related to low levels of DC.

OBJECTIVES: Metabolically obese but normal weight (MONW) individuals constitute a subgroup of normal weight individuals that display impaired insulin sensitivity with a higher risk of developing diabetes, cardiovascular disease and mortality. We aimed to propose a novel criterion for defining MONW by examining the usefulness and the cutoff value of the TyG index, a product of the levels of triglycerides and glucose, in identifying MONW individuals. In addition, the performance of this criterion in predicting the future incidence of diabetes was assessed. SUBJECTS/METHODS: A total of 7541 non-diabetic, normal weight (body mass index ⩾18.5 and <25 kg m(-)(2)) subjects were selected from the Korea National Health and Nutrition Examination Survey conducted in 2009-2010. Another 3185 participants with follow-up studies were selected from a prospective community-based cohort study. The TyG index was calculated as ln(fasting triglycerides (mg dl(-1)) × fasting glucose (mg dl(-1))/2). RESULTS: The levels of the TyG index paralleled the prevalence of metabolic syndrome and its components. The cutoff value of the TyG index that reflected MONW based on the receiver operating characteristics analysis was 8.82 for men and 8.73 for women, with the area under the curve values being 0.855 and 0.868, respectively. The sensitivity and the specificity were 84.2 and 77.6% in men and 69.1 and 89.4% in women, respectively. Individuals designated as MONW, who have a normal weight and TyG levels higher than cutoff, displayed a metabolically unhealthy phenotype and an approximately twofold higher risk of developing diabetes compared with metabolically healthy normal weight subjects. CONCLUSIONS: We propose a simple diagnostic criterion of MONW, which might be used to discriminate subjects with a higher risk of metabolic diseases.
ABSTRACT
AIM: This study investigated whether serum zinc concentration is associated with glucose tolerance, insulin resistance and metabolic health status in Korean adults. METHODS: Subjects with available serum zinc levels were recruited from the fifth Korea National Health and Nutrition Examination Survey (KNHANESV) cohort. Those in the highest quartile on homoeostasis model assessment for insulin resistance (HOMA-IR) and with a body mass index (BMI) of 18.5-25kg/m(2) were classified as metabolically obese and normal weight (MONW). RESULTS: A total of 1813 subjects with a mean age of 45.2±0.5 years and a mean BMI of 24.01±0.11kg/m(2) were enrolled. Those in the lower serum zinc quartiles exhibited higher levels of fasting blood glucose and insulin resistance indices compared with those in the higher quartiles. However, these associations were positive only in normal-weight subjects. Those categorized as MONW exhibited significantly lower serum zinc levels than the metabolically healthy and normal weight (MHNW) subjects (131.6±3.0µg/dL vs 141.7±2.8µg/dL, respectively; P=0.0026), whereas serum zinc levels did not differ according to metabolic health in obese subjects. The odds ratio for being categorized as MONW was 4.12 (95% CI: 1.75, 9.72) among those in the lowest serum zinc quartile compared with those in the highest quartile even after adjusting for possible confounding factors. CONCLUSION: Lower serum zinc levels were associated with unhealthy metabolic status in normal-weight adults. Further prospective studies are required to define the role of zinc in metabolic health.

BACKGROUND AND PURPOSE: Congenital superior oblique palsy is known to relate to trochlear nerve absence and a variable degree of superior oblique muscle hypoplasia. The purpose of this study was to determine whether superior oblique muscle volume predicts trochlear nerve absence in congenital superior oblique palsy. MATERIALS AND METHODS: A retrospective study of high-resolution MR imaging to evaluate the presence of the trochlear nerve and to measure superior oblique muscle areas and volumes with the image analysis tools of a PACS was performed in 128 consecutive patients with unilateral congenital superior oblique palsy and 34 age-matched healthy controls. RESULTS: Of the 128 patients with congenital superior oblique palsy, 88 had an ipsilateral trochlear nerve absence (absent group) and 40 had both trochlear nerves (present group). In patients with congenital superior oblique palsy, the paretic side superior oblique muscle volume was significantly smaller compared with the normal side only in the absent group (P < .001). The left and right side superior oblique muscle volumes were not significantly different in controls (P = .750), and the paretic and normal side superior oblique muscle volumes were not significantly different in the present group (P = .536). The cutoff value of the paretic/normal side superior oblique muscle volume ratio for diagnosing trochlear nerve absence was ≤0.75 (sensitivity 98.9%, specificity 95.0%) in patients with congenital superior oblique palsy. CONCLUSIONS: The ratio of paretic/normal side superior oblique muscle area and volume has an excellent predictability in diagnosing trochlear nerve absence in congenital superior oblique palsy.

BACKGROUND: Neoadjuvant chemotherapy has been shown to improve the rate of complete (R0) resection and downstaging in patients with localized gastric cancer. There are few reports, however, regarding its impact on postoperative morbidity and mortality. The aims of this study were to analyse complication and mortality rates after neoadjuvant chemotherapy using a modified regimen of folinic acid, 5-fluorouracil and oxaliplatin (mFOLFOX6) for locally advanced gastric cancer (AGC), compared with rates in patients who underwent surgery without neoadjuvant chemotherapy. METHODS: Data were collected from patients with AGC enrolled in a phase II trial of four cycles of neoadjuvant mFOLFOX6 followed by surgery, between January 2005 and June 2008 at two of three institutions, and compared with those from a cohort of patients with AGC who underwent surgery alone at one of the institutions in 2006. RESULTS: Among 51 patients who received neoadjuvant chemotherapy, there were no deaths and a morbidity rate of 24 per cent after surgery. Comparison of 48 patients in one institution who received neoadjuvant chemotherapy with 92 patients who had surgery alone in the same institution showed no increase in postoperative morbidity (23 versus 29 per cent; P = 0·417). Combined resection was the only risk factor for postoperative morbidity after neoadjuvant chemotherapy. CONCLUSION: Neoadjuvant chemotherapy with mFOLFOX is a safe treatment for patients with localized AGC, and does not increase postoperative morbidity or mortality.
