Abstract
PURPOSE Despite their similar clinical characteristics, appendiceal diverticulitis (AD) and acute appendicitis (AA) are pathologically distinct. This study compared the clinical features of AD and AA and identified relevant risk factors. METHODS Patients who underwent appendectomy with a preoperative diagnosis of either AD or AA were categorized based on histopathological findings. The two groups were compared in terms of various clinical factors. RESULTS Among the 854 patients included in the study, a histopathological evaluation revealed 49 and 805 cases of AD and AA, respectively. A univariate analysis demonstrated that AD was more prevalent than AA among older, taller, and heavier males. A multivariate analysis revealed that male sex, a white blood cell (WBC) count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a mean corpuscular volume (MCV) ≥ 91.6 fL were significant factors differentiating AD from AA. In addition, pathological AD emerged as an independent risk factor for abscess and/or perforation. CONCLUSIONS AD was associated with an older age, robust physique, and significant risk of abscess and/or perforation despite a low WBC count. In addition to imaging modalities, the preoperative factors of male sex, a WBC count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a MCV ≥ 91.6 fL may be useful for distinguishing AD from AA.

Abstract
AIM OF THE STUDY Mean corpuscular volume (MCV) has shown mounting evidence as a prognostic indicator in a number of malignancies. The aim of this study was to examine the prognostic potential of pretherapeutic MCV among patients with pancreatic ductal adenocarcinoma (PDAC) who underwent upfront resection or resection after neoadjuvant treatment (NT). PATIENTS AND METHODS Consecutive patients with PDAC who underwent pancreatic resection between 1997 and 2019 were included in this study. Neoadjuvantly treated patients' serum MCV was measured before NT and before surgery. In patients undergoing upfront resection serum MCV was measured before surgery. Median MCV values were used as cut-off to distinguish high from low MCV values. RESULTS Five hundred and forty-nine (438 upfront resected and 111 neoadjuvantly treated) patients were included in this study. Multivariate analysis revealed, that high MCV before and after NT, were independent negative prognostic factors for overall survival (P<0.01, respectively). Furthermore, the median MCV value from before to after NT increased significantly (P<0.001, Wilcoxon signed-rank test) and was (P=0.03, Wilcoxon rank sum test) associated with tumor response to NT. CONCLUSION High MCV is an independent adverse prognostic factor in patients with resectable neoadjuvantly treated PDAC and may qualify as useful indicator to help physicians to provide personalized prognostication.

Abstract
Objective To establish the prognostic value of mean corpuscular volume (MCV) in patients with esophageal squamous cell carcinoma (ESCC) who have undergone esophagectomy. Background The MCV increases in patients with high alcohol and tobacco consumption. Such a lifestyle can be a risk factor for malnutrition, comorbidities related to those habits, and multiple primary malignancies, which may be associated with frequent postoperative morbidity and poor prognosis. Methods This study included 1673 patients with ESCC who underwent curative esophagectomy at eight institutes between April 2005 and November 2020. Patients were divided into normal and high MCV groups according to the standard value of their pretreatment MCV. Clinical background, short-term outcomes, and prognosis were retrospectively compared between the groups. Results Overall, 26.9% of patients had a high MCV, which was significantly associated with male sex, habitual smoking and drinking, multiple primary malignancies, and malnutrition, as estimated by the body mass index, hemoglobin and serum albumin values, and the Geriatric Nutritional Risk Index. Postoperative respiratory morbidity (P = 0.0075) frequently occurred in the high MCV group. A high MCV was an independent prognostic factor for worse overall survival (hazard ratio, 1.27; 95% confidence interval, 1.049-1.533; P = 0.014) and relapse-free survival (hazard ratio, 1.23; 95% confidence interval, 1.047-1.455; P = 0.012). Conclusions A high MCV correlates with habitual drinking and smoking, malnutrition, and multiple primary malignancies and could be a surrogate marker of worse short-term and long-term outcomes in patients with ESCC who undergo esophagectomy.

Abstract
BACKGROUND Elevated mean corpuscular volume (MCV) is associated with a diminished prognosis for various tumor entities. This study aimed to evaluate the association between preoperative serum MCV levels and both overall (OS) and disease-free survival (DFS) for patients with resectable adenocarcinomas of the esophagogastric junction (AEG). METHODS This study included consecutive patients undergoing surgical resection between 1992 and 2016. Measured preoperative MCV levels were stratified into quintiles and correlated with patients' survival and clinicopathologic characteristics. RESULTS The study analyzed 314 patients with a median OS of 36.8 months and a median DFS of 20.6 months. The multivariate analysis showed that preoperatively elevated MCV is a significant prognostic factor for OS (hazard ratio [HR], 1.05; 95% confidence interval [CI], 1.03-1.08; P < 0.001) and DFS (HR, 1.05; 95% CI, 1.03-1.08; P < 0.001). In the subgroup analysis of neoadjuvantly treated and untreated patients, MCV remained an independent prognostic factor for OS (HR, 1.08; 95% CI, 1.04-1.12; P < 0.001) and DFS (HR, 1.07; 95% CI, 1.03-1.12; P < 0.001) in both groups. In the univariate analysis, tumor stage and differentiation, adjuvant chemotherapy, MCV, mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly correlated with diminished OS and DFS. CONCLUSION Preoperatively elevated MCV is an independent prognostic factor for patients with adenocarcinomas of the esophagus and the gastroesophageal junction.

Abstract
Genetic polymorphisms of alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) modulate exposure levels to ethanol/acetaldehyde. Endoscopic screening of 6,014 Japanese alcoholics yielded high detection rates of esophageal squamous cell carcinoma (SCC; 4.1%) and head and neck SCC (1.0%). The risks of upper aerodigestive tract SCC/dysplasia, especially of multiple SCC/dysplasia, were increased in a multiplicative fashion by the presence of a combination of slow-metabolizing ADH1B*1/*1 and inactive heterozygous ALDH2*1/*2 because of prolonged exposure to higher concentrations of ethanol/acetaldehyde. A questionnaire asking about current and past facial flushing after drinking a glass (≈180 mL) of beer is a reliable tool for detecting the presence of inactive ALDH2. We invented a health-risk appraisal (HRA) model including the flushing questionnaire and drinking, smoking, and dietary habits. Esophageal SCC was detected at a high rate by endoscopic mass-screening in high HRA score persons. A total of 5.0% of 4,879 alcoholics had a history of (4.0%) or newly diagnosed (1.0%) gastric cancer. Their high frequency of a history of gastric cancer is partly explained by gastrectomy being a risk factor for alcoholism because of altered ethanol metabolism, e.g., by blood ethanol level overshooting. The combination of H. pylori-associated atrophic gastritis and ALDH2*1/*2 showed the greatest risk of gastric cancer in alcoholics. High detection rates of advanced colorectal adenoma/carcinoma were found in alcoholics, 15.7% of 744 immunochemical fecal occult blood test (IFOBT)-negative alcoholics and 31.5% of the 393 IFOBT-positive alcoholics. Macrocytosis with an MCV≥106 fl increased the risk of neoplasia in the entire aerodigestive tract of alcoholics, suggesting that poor nutrition as well as ethanol/acetaldehyde exposure plays an important role in neoplasia.

Abstract
BACKGROUND Oxidation of ethanol by alcohol dehydrogenase (ADH) generates acetaldehyde (AcH), which is converted to acetate by aldehyde dehydrogenase-2 (ALDH2). Roughly 40% of East Asians are ALDH2-deficient due to an inactive enzyme encoded by the ALDH2*2 allele. ALDH2-deficient individuals have a dramatically elevated risk of esophageal cancer from alcohol consumption. METHODS We investigated the relationship between ALDH2*2, ADH1B*2 (encoding a highly active ADH) and erythrocyte abnormalities, in a population of Japanese alcoholic men (N = 1,238). RESULTS Macrocytosis (mean corpuscular volume [MCV] ≥100 fl) and macrocytic anemia (MCV ≥100 fl and hemoglobin <13.5 g/dl) were found in 62.4 and 24.1% of the subjects, respectively. Age-adjusted daily alcohol consumption did not differ according to ADH1B and ALDH2 genotypes. However, macrocytosis and macrocytic anemia were strongly associated with the ALDH2*1/*2 genotype multivariate odds ratios (ORs; 95% confidence interval [CI] = 2.85 [1.95 to 4.18] and 3.68 [2.64 to 5.15], respectively, versus ALDH2*1/*1). In comparison with the ADH1B*1/*1 and ALDH2*1/*1 genotype combination, the ADH1B*1/*1 and ALDH2*1/*2 genotype combination and the ADH1B*2 allele and ALDH2*1/*2 genotype combination increased stepwise the ORs (95% CI) for macrocytosis (1.65 [0.92 to 2.94] and 4.07 [2.33 to 7.11], respectively, p for difference in OR = 0.015) and macrocytic anemia (2.80 [1.52 to 5.15] and 5.32 [3.29 to 8.62], respectively, p for difference in OR = 0.045). Genotype effects were more prominent on the risks of the more advanced erythrocyte abnormalities. Older age, cigarette smoking, and low body mass index independently increased the risks of the erythrocyte abnormalities. Consumption of beer, which contains folate, decreased the risks, whereas consumption of alcoholic beverages lacking folate did not. CONCLUSIONS These results suggest that the erythrocyte abnormalities in alcoholics are attributable to high AcH exposure as well as to nutritional deficiencies and may be prevented by folate.

Abstract
Alcohol dependence (AD) is a moderately heritable phenotype with a small number of known risk genes mapped via linkage or candidate gene studies. We considered 313 males from among 595 members of documented, extended pedigrees in which AD segregates collected in Northern Hunan Province, China. A joint analysis of both males and females could not be performed as the difference in alcohol consumption variance was too large. Genome-wide association analyses were performed for approximately 300,000 single nucleotide polymorphisms (SNPs). Significant associations found in the ALDH2 region for AD (minimum P = 4.73 × 10(-8)) and two AD-related phenotypes: flushing response (minimum P = 4.75 × 10(-26)) and maximum drinks in a 24-hr period (minimum P = 1.54 × 10(-16)). Association of previous candidate SNP, rs10774610 in CCDC63, was confirmed but resulted from linkage disequilibrium with ALDH2. ALDH2 is strongly associated with flushing response, AD, and maximum drinks in males, with nonsynonymous SNP rs671 explaining 29.2%, 7.9%, and 22.9% of phenotypic variation, respectively, in this sample. When rs671 was considered as a candidate SNP in females, it explained 23.6% of the variation in flushing response, but alcohol consumption rates were too low among females-despite familial enrichment for AD-for an adequate test of association for either AD or maximum drinks. These results support a mediating effect of aldehyde dehydrogenase deficiency on alcohol consumption in males and a secondary, culturally mediated limitation on alcohol consumption by females that should be appropriately modeled in future studies of alcohol consumption in populations where this may be a factor.

Abstract
Quantification of the association between the intake of fruit and vegetables and risk of esophageal squamous cell carcinoma (ESCC) is controversial even though several studies have explored this association. We summarized the evidence from observational studies in categorical, linear and non-linear dose-response meta-analyses. Eligible studies published up to 31 July 2012 were retrieved via computer searches of MEDLINE and EMBASE as well as manual review of references. Random-effects models were used to calculate summary relative risks (SRRs) and the corresponding 95% confidence intervals (CIs). A total of 32 studies involving 10,037 cases of ESCC were included in this meta-analysis. The SRRs for the highest vs. lowest intake were 0.56 (95% CI: 0.45-0.69) for vegetable intake and 0.53 (95% CI: 0.44-0.64) for fruit intake (pheterogeneity <0.001 for both). Similar results were observed in a linear dose-response analysis. There was evidence of non-linear associations for intakes of fruit (pnon-linearity <0.001) and vegetables (pnon-linearity =0.041). There was no evidence of publication bias. These data support the hypothesis that intakes of vegetables and fruit may significantly reduce the risk of ESCC. Further investigation with prospective designs, validated questionnaires and good control of important confounders is warranted.

Abstract
The ethanol in alcoholic beverages and the acetaldehyde associated with alcohol consumption are Group 1 human carcinogens (WHO, International Agency for Research on Cancer). The combination of alcohol consumption, tobacco smoking, the inactive heterozygous aldehyde dehydrogenase-2 genotype (ALDH2*1/*2) and the less-active homozygous alcohol dehydrogenase-1B genotype (ADH1B*1/*1) increases the risk of squamous cell carcinoma (SCC) in the upper aerodigestive tract (UADT) in a multiplicative fashion in East Asians. In addition to being exposed to locally high levels of ethanol, the UADT is exposed to a very high concentration of acetaldehyde from a variety of sources, including that as an ingredient of alcoholic beverages per se and that found in tobacco smoke; acetaldehyde is also produced by salivary microorganisms and mucosal enzymes and is present as blood acetaldehyde. The inefficient degradation of acetaldehyde by weakly expressed ALDH2 in the UADT may be cri! tical to the local accumulation of acetaldehyde, especially in ALDH2*1/*2 carriers. ADH1B*1/*1 carriers tend to experience less intense alcohol flushing and are highly susceptible to heavy drinking and alcoholism. Heavy drinking by persons with the less-active ADH1B*1/*1 leads to longer exposure of the UADT to salivary ethanol and acetaldehyde. The ALDH2*1/*2 genotype is a very strong predictor of synchronous and metachronous multiple SCCs in the UADT. High red cell mean corpuscular volume (MCV), esophageal dysplasia, and melanosis in the UADT, all of which are frequently found in ALDH2*1/*2 drinkers, are useful for identifying high-risk individuals. We invented a simple flushing questionnaire that enables prediction of the ALDH2 phenotype. New health appraisal models that include ALDH2 genotype, the simple flushing questionnaire, or MCV are powerful tools for devising a new strategy for prevention and screening for UADT cancer in East Asians.

Abstract
Some Japanese exhibit facial flushing after drinking alcohol. Facial flushing was considered to be caused by acetaldehydemia. The concentration of blood acetaldehyde was concerned with the catalytic activity of acetaldehyde dehydrogenase (ALDH). Acetaldehyde dehydrogenase (ALDH)-2 polymorphism (rs671, Glu504Lys) was known to be associated with upper aerodigestive tract (UAT) cancer due to modulation of ALDH2 enzyme activity. It remains controversial whether facial flushing is useful in predicting UAT cancer risk as a surrogate marker of ALDH2 polymorphism. We conducted a case-control study to assess the risk of UAT cancer and facial flushing and ALDH2 polymorphism. Cases and controls were 585 UAT cancer patients and matched 1170 noncancer outpatients of Aichi Cancer Center Hospital. Information on facial flushing and other lifestyle factors was collected via a self-administered questionnaire. Association between facial flushing, polymorphism, and UAT cancer was assessed by odds ratios and 95% confidence intervals by using conditional logistic regression models. The facial flushing had no significant association with UAT cancer, although ALDH2 Lys allele was significantly associated with UAT cancer. No significant interaction between facial flushing and alcohol consumption was observed in this study, whereas ALDH2 Lys allele had significant association with UAT cancer. The misclassification between facial flushing and ALDH2 genotype was observed in 18% of controls with ALDH2 Glu/Glu genotype and in 16% of controls with ALDH2 Glu/Lys genotype. Facial flushing was less useful to predict UAT cancer risk than genotyping ALDH2 polymorphism.

Abstract
BACKGROUND Because early squamous cell carcinoma (SCC) of the esophagus is detectable by endoscopic esophageal iodine staining with high accuracy and is easily treated by endoscopic mucosectomy, it is important to develop efficient methods for screening candidates for the endoscopic examination. Inactive aldehyde dehydrogenase-2 (ALDH2) is a very strong risk factor for esophageal SCC in alcohol drinkers and thus may be suitable as a screening tool. PURPOSE To assess the performance of health risk appraisal (HRA) models in screening for esophageal SCC in the Japanese male population. METHODS Two types of HRA models were developed based on our previous case-control study, which included assessment of ALDH2 activity and selected risk factors (HRA-G and HRA-F: activities of ALDH2 assessed by genotype and questionnaire for alcohol flushing, respectively). Each individual's risk of esophageal SCC was calculated quantitatively as a risk score. The sensitivity and specificity of the HRA models at various cutoff values of risk score was estimated by a leave-one-out cross-validation. The positive predictive value was estimated assuming the prevalence of esophageal SCC in the whole population to be 0.17% or 0.39% according to literatures. RESULTS When individuals ranked in the top 10% of the HRA-F risk score was screened, the sensitivity was 57.9% and positive predictive value was 0.93% or 2.12% according to the above assumptions, respectively. The sensitivity was slightly better by the HRA-G model than by the HRA-F model. CONCLUSION The HRA models may provide an important approach to early intervention strategies to control esophageal SCC in Japanese men.

Abstract
BACKGROUND Gastric carcinoma occurs at a high rate in alcoholic Japanese men. Inactive heterozygous aldehyde dehydrogenase-2 (ALDH2*1/2*2) and macrocytosis (mean corpuscular volume [MCV] > or = 106 fl) enhance the risk for esophageal carcinoma, which frequently occurs with gastric carcinoma in this population. Whether alcoholism affects Helicobacter pylori-induced chronic atrophic gastritis (CAG) is unknown. METHODS This study of Japanese alcoholic men with (n = 45) and without (n = 281) gastric carcinoma included assessment of H. pylori IgG antibody, serum pepsinogen-confirmed CAG, MCV, and ALDH2 genotype. RESULTS The gastric carcinoma cases had a significantly higher age-adjusted prevalence of H. pylori-positivity (78%vs 57%), CAG (78%vs 42%), ALDH2*1/2*2 (36%vs 14%), MCV > or =106 fl (38%vs 20%), and concurrent esophageal/oropharyngolaryngeal carcinoma (18%vs 5%) than controls. Among gastric cancer-free controls, the prevalence of CAG was higher than generally reported in Japan, regardless of H. pylori status (H. pylori-positive, 56%vs 35-36% for Japanese general population; H. pylori-negative, 8%vs 1-3%). Alcoholism may accelerate the progression of CAG. Each of these factors increased the risk of gastric carcinoma (OR(s) = 3.7 for H. pylori-positive, 2.7 for non-severe CAG, 8.7 for severe CAG, 3.5 for ALDH2*1/2*2, 2.5 for MCV > or =106 fl, and 3.7 for concurrent carcinoma). A multivariate analysis showed that CAG and ALDH2*1/2*2 were independently related to the risk of gastric carcinoma. Combinations of CAG and ALDH2*1/2*2 showed greater risks of gastric carcinoma (OR(s) = 4.0 for non-severe CAG alone, 17.6 for severe CAG alone, 9.7 for ALDH2*1/2*2 alone, 17.1 for non-severe CAG plus ALDH2*1/2*2, and 39.2 for severe CAG plus ALDH2*1/2*2). CONCLUSIONS Combining blood tests for H. pylori, CAG, MCV and ALDH2 genotype could offer a new means of predicting risk of gastric carcinoma in Japanese alcoholic men.
