Cancer incidence and mortality: A cohort study in China, 2008-2013. Pan Rui,Zhu Meng,Yu Canqing,Lv Jun,Guo Yu,Bian Zheng,Yang Ling,Chen Yiping,Hu Zhibin,Chen Zhengming,Li Liming,Shen Hongbing, International journal of cancer The National Central Cancer Registry of China (NCCR) was the only available source of cancer monitoring in China, even though only about 70% of cancer registration sites were qualified by now. In this study, based on a national large prospective cohort-the China Kadoorie Biobank (CKB), we aimed to provide additional cancer statistics and compare the difference of cancer burden between urban and rural areas of China. A total of 497,693 cancer-free participants aged 35-74 years were recruited and successfully followed up from 2004 to 2013 in 5 urban and 5 rural areas across China. Except for traditional registration systems, the national health insurance system and active follow-up were used to determine new cancer incidents and related deaths. The mortality-to-incidence ratio (MIR) was used to compare the differences of cancer burden between urban and rural areas of China. We found that cancer mortality coincided well between our cohort and NCCR, while the incidence was much higher in our cohort. Based on CKB, we found the MIR of all cancers was 0.54 in rural areas, which was approximately one-third higher than that in urban areas with 0.39. Cancer profiles in urban areas were transiting to Western distributions, which were characterized with high incidences of breast cancer and colorectal cancer; while cancers of the esophagus, liver and cervix uteri were still common in rural areas of China. Our results provide additional cancer statistics of China and demonstrate the differences of cancer burden between urban and rural areas of China. 10.1002/ijc.30825

Association of Frequency of Organic Food Consumption With Cancer Risk: Findings From the NutriNet-Santé Prospective Cohort Study. Baudry Julia,Assmann Karen E,Touvier Mathilde,Allès Benjamin,Seconda Louise,Latino-Martel Paule,Ezzedine Khaled,Galan Pilar,Hercberg Serge,Lairon Denis,Kesse-Guyot Emmanuelle JAMA internal medicine Importance:Although organic foods are less likely to contain pesticide residues than conventional foods, few studies have examined the association of organic food consumption with cancer risk. Objective:To prospectively investigate the association between organic food consumption and the risk of cancer in a large cohort of French adults. Design, Setting, and Participants:In this population-based prospective cohort study among French adult volunteers, data were included from participants with available information on organic food consumption frequency and dietary intake. For 16 products, participants reported their consumption frequency of labeled organic foods (never, occasionally, or most of the time). An organic food score was then computed (range, 0-32 points). The follow-up dates were May 10, 2009, to November 30, 2016. Main Outcomes and Measures:This study estimated the risk of cancer in association with the organic food score (modeled as quartiles) using Cox proportional hazards regression models adjusted for potential cancer risk factors. Results:Among 68 946 participants (78.0% female; mean [SD] age at baseline, 44.2 [14.5] years), 1340 first incident cancer cases were identified during follow-up, with the most prevalent being 459 breast cancers, 180 prostate cancers, 135 skin cancers, 99 colorectal cancers, 47 non-Hodgkin lymphomas, and 15 other lymphomas. High organic food scores were inversely associated with the overall risk of cancer (hazard ratio for quartile 4 vs quartile 1, 0.75; 95% CI, 0.63-0.88; P for trend = .001; absolute risk reduction, 0.6%; hazard ratio for a 5-point increase, 0.92; 95% CI, 0.88-0.96). Conclusions and Relevance:A higher frequency of organic food consumption was associated with a reduced risk of cancer. If these findings are confirmed, further research is necessary to determine the underlying factors involved in this association. 10.1001/jamainternmed.2018.4357

Prevalence and natural course of occult hepatitis B virus infection in residents of 2 communities of Wuwei City, Gansu Province, China. Wen X,Su H,Wang Y,Pu Z,Gao J,Ji Z,Yuan X,Li X,Zhang W,Zhang L,Long Y,Yan Y,Shao Z Journal of viral hepatitis Occult hepatitis B infection (OBI) is characterized by serum hepatitis B surface antigen (HBsAg) negative and hepatitis B virus (HBV) DNA positive (HBsAg-/HBV DNA+). Occult hepatitis B infection in community-based populations has been scarcely investigated, and OBI outcomes remain unclear, especially in Wuwei, a region located in Northwest China. This region is one of the areas in China that has the highest prevalence of chronic HBV infection. A prospective study was performed in the general population of 2 towns of Wuwei from June 2011 to May 2014. A questionnaire was used to collect demographic and medical data, and serum samples were collected from the participants and stored until analysis. DNA was detected using quantitative PCR (qPCR) or nested PCR, the HBV DNA from HBV DNA-positive or possible positive (below the detection limit) subjects was extracted and amplified by nested PCR, and the PCR products were sequenced. Sequence analysis was performed using the Mega 6.0 program and CLC sequence viewer software. Hepatitis B virus DNA was detected in 90 of 3,080 HBsAg-negative subjects, and the prevalence of OBI in the study population was 2.92% (90/3,080, 95% CI: 2.33%-3.51%). Hepatitis B virus genomes in 51 of 80 objects (63.75%) contained mutations in the "a" determinant of HBsAg. After 2 years follow-up, 42 of 90 HBV DNA of OBI subjects remained positive, and the natural clearance rate of OBI subjects was 53.3%. Occult hepatitis B infection prevalence in this cohort was much lower than chronic HBV infection in the same region. HBV DNA was cleared in most OBI subjects during the 2 year period. Our data suggest that some OBI may represent a late stage of resolving the HBV infection process. 10.1111/jvh.12805

Obesity, peptic ulcer disease and metabolic status in the Wuwei Cohort of northwest China: A cross-sectional study. Asia Pacific journal of clinical nutrition BACKGROUND AND OBJECTIVES:Peptic ulcer disease is a common digestive system disease. However, whether peptic ulcer disease and obesity are related is unclear. We assessed the associations of obesity and metabolic status with peptic ulcer disease. METHODS AND STUDY DESIGN:We conducted a cross-sectional study of 3561 individuals from the Wuwei cohort. We evaluated the associations of general and abdominal adiposity, as defined by different anthropometric indices, with peptic ulcer disease. Odds ratios and 95% confidence intervals were determined through binary logistic regression. RESULTS:The odds ratio for peptic ulcer disease was 2.37 (1.46-3.84) for women with obesity, compared with the normal group. The association remained significant in Models 2 and 3, with odds ratios of 2.23 (1.35-3.69) and 2.03 (1.19-3.49), respectively. In Model 1, women with obesity had an odds ratio for duodenal ulcer of 2.76 (1.41-5.42) compared with the control group; this result remained significant in Models 2 and 3, with odds ratios of 2.52 (1.24-5.13) and 2.44 (1.13-5.28), respectively. In Model 1, women with metabolically healthy and unhealthy obesity had odds ratios for peptic ulcer disease of 2.26 (1.19-4.28) and 2.15 (1.12-4.15), respectively, compared with the control group. After adjustments for major covariates and H. pylori status, these respective odds ratios became 2.27 (1.20-4.30) and 2.17 (1.12-4.20) in Model 2 and 2.2 (1.15-4.20) and 2.16 (1.11-4.19) in Model 3. CONCLUSIONS:General adiposity defined by body mass index is associated with peptic ulcer disease in women. 10.6133/apjcn.202206_31(2).0015

Habitually Skipping Breakfast Is Associated with the Risk of Gastrointestinal Cancers: Evidence from the Kailuan Cohort Study. Journal of general internal medicine BACKGROUND:Habitually skipping breakfast may promote the initiation and progression of gastrointestinal (GI) cancers, which have never been systematically explored in large-scale prospective studies. METHODS:We prospectively examined the effects of breakfast frequency on the occurrence of GI cancers among 62,746 participants. The hazard ratios (HRs) and 95% confidence intervals (95% CIs) of GI cancers were calculated by Cox regression. The CAUSALMED procedure was used to perform the mediation analyses. RESULTS:During a median follow-up of 5.61 (5.18 ~ 6.08) years, 369 incident GI cancer cases were identified. Participants who consumed 1-2 times breakfasts per week exhibited an increased risk of stomach (HR = 3.45, 95% CI: 1.06-11.20) and liver cancer (HR = 3.42, 95% CI: 1.22-9.53). Participants who did not eat breakfast had an elevated risk of esophageal (HR = 2.72, 95% CI: 1.05-7.03), colorectal (HR = 2.32, 95% CI: 1.34-4.01), liver (HR = 2.41, 95% CI: 1.23-4.71), gallbladder, and extrahepatic bile duct cancer (HR = 5.43, 95% CI: 1.34-21.93). In the mediation effect analyses, BMI, CRP, and TyG (fasting triglyceride-glucose) index did not mediate the association between breakfast frequency and the risk of GI cancer incidence (all P for mediation effect > 0.05). CONCLUSIONS:Habitually skipping breakfast was associated with a greater risk of GI cancers including esophageal, gastric, colorectal, liver, gallbladder, and extrahepatic bile duct cancer.

Meat consumption and risk of esophageal and gastric cancer in the Golestan Cohort Study, Iran. International journal of cancer Red meat and processed meat are associated with some gastrointestinal cancers. Our study aims to investigate the association of different meat types with esophageal and gastric cancer (EC, GC) in a high-risk population. The Golestan Cohort Study (GCS) is a population-based cohort of 50 045 individuals aged 40 to 75 from northeast Iran. Detailed data on different exposures were collected using validated questionnaires. We considered quintiles of meat consumption, using grams and density (g/1000 kcal/day). We calculated intake of red, processed, organ and white meat, as well as total red meat, including the first three. We used proportional hazards regression models to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for the association between meat types and cancer. During 12 years of follow-up, out of 49 585 participants (57.4% women), 369 developed EC (48.2% women) and 368 developed GC (27.5% women), including 309 esophageal squamous cell, 20 esophageal adenocarcinomas, 216 cardia and 95 non-cardia GC. No association was found for EC except for red meat among females (HR for one quintile increase 1.13, 95% CI = 1.00-1.27). The risk of GC increased for intake of total red meat (HR 1.08, 95% CI = 1.00-1.17) and red meat separately (HR 1.09, 95% CI = 1.00-1.18). The HR for red meat and non-cardia GC was 1.23 (95% CI = 1.02-1.48). No associations were observed for other types of meat. In conclusion, in this high-risk population red meat intake is associated with GC, but not EC, suggesting a substantial role of this modifiable factor in determining the burden of GC. 10.1002/ijc.34056

The relationship between dietary patterns, dietary quality index, and dietary inflammatory index with the risk of all types of cancer: Golestan cohort study. Nojomi Marzieh,Tehrani Banihashemi Arash,Niksima Hassan,Hashemian Maryam,Mottaghi Azadeh,Malekzaddeh Reza Medical journal of the Islamic Republic of Iran Dietary patterns and diet quality index (DQI) are widely discussed in relation with different health conditions and have recently been taken into consideration for all cancer types. Since chronic inflammation has been recognized as an important biologic risk factor for cancer occurrence, especially in epithelial tissues, proinflammatory or anti-inflammatory characteristics of diet has become the center of attention. In the present study, we aimed to identify whether a specific dietary pattern, Mediterranean dietary score (MDs), and dietary inflammatory index (DII) were associated with overall cancer risk in Iranian population. This study was performed in the context of the Golestan cohort study. Participants with extreme daily energy intake or those who did not answer more than 30 question of the Food Frequency questionnaire (FFQ) were excluded. Dietary patterns, MDs, and DII were measured from FFQ. Age, sex, total energy, place of residence, smoking, wealth score, ethnicity, opiate use, BMI, education, marital status, and physical activity score were considered as confounding variables. Using Cox proportional hazards regression models, hazard ratios (HRs) and 95% confidence interval of cancer were estimated. HRs (95% CIs) of all cancers by quartiles of Western dietary pattern, DII, and MDs showed that the forth quartile of the Western dietary pattern is attributed to 23% higher cancer risk (HRs: 1.23, CI: 1.09-1.40, P< 0.001, adjusted for age and sex) compared to the first quartile. It also remained significant after further adjustments (HRs = 1.20, CI: 1.06-1.36, P< 0.001). There was a higher cancer risk in the fourth quartile of DII in comparison with the first quartile (HRs = 1.16, CI: 1.01-1.32, P trend < 0.001, adjusted for age and sex). The lower adherence to the Mediterranean dietary pattern also largely contributes to 27% higher cancer risk (HRs: 1.27, CI: 1.12-1.44), P trend < 0.001, adjusted for age and sex), which also remained remarkable after further adjustments ((HRs =1.19, CI: 1.05-1.35, P trend < 0.001). Cancer is highly correlated to dietary intake and dietary patterns, such as the Western dietary pattern, while the Mediterranean diet score was inversely associated with cancer risk. Further investigations are required to get a broader insight into cancer determinants in population. 10.47176/mjiri.35.48

Dietary intake of fatty acids and risk of pancreatic cancer: Golestan cohort study. Ghamarzad Shishavan Neda,Masoudi Sahar,Mohamadkhani Ashraf,Sepanlou Sadaf G,Sharafkhah Maryam,Poustchi Hossein,Mohamadnejad Mehdi,Hekmatdoost Azita,Pourshams Akram Nutrition journal BACKGROUND:As pancreatic cancer (PC) is a malignancy with poor prognosis, finding strategies for its prevention became a notable priority. Among all the factors influencing the risk of PC, dietary items especially fats are considered as the most modifiable risk factors.This study is designed to assess the associations of dietary intake of fatty acids with the risk of PC incidence. METHODS:A total of 50,045 adults between 40 and 75 years old participated in this cohort study in 2004-2008 and were followed up to the present. Intakes of fatty acids was evaluated by validated food-frequency questionnaire (FFQ). Cox proportional hazards regression model was used to estimate hazard ratio (HR) with 95 % confidence interval of differing levels of dietary intakes of fatty acids for incidence of PC. RESULTS:At the end of follow-up period, 76 cases of PC were identified and 46,904 participants without history of cancer, acute kidney disorders, fibrosis and cirrhosis were included in the study. Dietary total saturated fatty acids (SFAS) was associated with PC risk (HR = 1.05 (1.01-1.09), P=0.01), whereas dietary total monounsaturated fatty acids (MUFAS) was inversely associated with the risk of PC (HR = 0.92 (0.86-0.99), P=0.04). Dietary total polyunsaturated fatty acids (PUFAS) did show a protective but not significant association with the risk of PC (HR = 0.91(0.84-1.00), P=0.05). CONCLUSIONS:The amount of total fat intake is not a risk factor for PC in our study and focusing on the intake of specific fatty acids becomes more striking. Unsaturated fatty acids including PUFAS and especially MUFAS are considered as protective dietary factors in PC prevention. In contrast, total SFAS is positively associated with the increased risk of PC. However, very long chain and odd-chain saturated fatty acids intake may be protective against PC. 10.1186/s12937-021-00723-3

Dietary quality using four dietary indices and lung cancer risk: the Golestan Cohort Study (GCS). Cancer causes & control : CCC PURPOSE:The lung cancer incidence in Iran has increased almost ten times over the past three decades. In addition to the known causes such as smoking and certain occupational exposure, dietary quality has been suggested to play a role in lung cancer. We aim to explore the association between dietary pattern and lung cancer risk among a Middle East population. METHODS:Data came from Golestan Cohort Study which included 48,421 participants with 136 lung cancer cases diagnosed during a median follow-up of 12 years. Multivariable Cox proportional hazards regression models were used to calculate the HRs and 95% CI of lung cancer risk by tertile of the four dietary index scores-the Health Eating Index (HEI)-2015, the Alternative Health Eating Index (AHEI)-2010, the Alternative Mediterranean Diet (AMED), and the Dietary Approach to Stop Hypertension (DASH)-Fung. RESULTS:A higher DASH-Fung score was inversely associated with risk of lung cancer after adjusting for potential confounders (tertile three vs. tertile one: HR = 0.59 (0.38-0.93); p for trend = 0.07), and p with smoking was 0.46. Similar findings were observed among current smokers with the HEI-2015 score (tertile three vs. tertile one: HR = 0.22 (0.08-0.60): p for trend < 0.01), and p between smoking and the HEI-2015 score was 0.03. CONCLUSION:In the GCS, consuming a diet more closely aligned with the DASH diet was associated with a reduced risk of lung cancer, which appeared to be independent of smoking status. There was also an inverse link between the HEI-2015 score and lung cancer risk among current smokers. Our finding is particularly important for the Middle East population, as diet may play an important role in cancer prevention and overall health. 10.1007/s10552-021-01400-w

Dietary acid load and mortality from all causes, CVD and cancer: results from the Golestan Cohort Study. The British journal of nutrition Given the limited studies and controversial results on association between dietary acid load and mortality from CVD and cancers, we aimed to investigate this association in a large population cohort study in Middle East, with a wide range of dietary acid load. The study was conducted on the platform of the Golestan Cohort Study (GCS), which enrolled 50 045 participants in 2004-2008. Dietary intake was assessed using a validated FFQ. Dietary potential renal acid load (PRAL) score was calculated from nutrient intake. Death and its causes were identified and confirmed by two or three physicians. Cox proportional hazards regression was used to estimate hazard ratio (HR) and 95 % CI for total and cause-specific mortalities. Then, the associations were modelled using restricted cubic splines. PRAL range was -57·36 to +53·81 mEq/d for men and -76·70 to +49·08 for women. During 555 142 person-years of follow-up, we documented 6830 deaths, including 3070 cardiovascular deaths, 1502 cancer deaths and 2258 deaths from other causes. For overall deaths, in final model after adjustment for confounders, participants in the first and fifth quintiles of PRAL had a higher risk of mortality compared with the second quintile of PRAL (HR: 1·08; 95 % CI1·01, 1·16 and HR: 1·07; 95 % CI 1·01, 1·15, respectively); < 0·05). Participants in the first and fifth quintiles of PRAL had a 12 % higher risk of CVD mortality compared with the Q2 of PRAL (HR: 1·12; 95 % CI 1·01-1·25 and HR: 1·12; 95 % CI 1·01, 1·26, respectively; < 0·05). We found that all-cause and CVD mortality rates were higher in the lowest and highest PRAL values, in an approximately U-shaped relation (-values for the overall association and the non-linear association of energy-adjusted PRAL with total mortality were < 0·001 and < 0·001, and with CVD mortality were 0·008 and 0·003, respectively). Our results highlight unfavourable associations of high acidity and alkalinity of diet with the increased total and CVD mortality risk. It may be important to consider a balanced acid-base diet as a protective strategy to prevent pre-mature death, especially from CVD. 10.1017/S0007114521003135

A Case-Control Study of Breast Cancer in Northeast of Iran: The Golestan Cohort Study. Alipour Sadaf,Omranipour Ramesh,Malekzadeh Reza,Poustchi Hossein,Pourshams Akram,Khoshnia Masoud,Gharavi Abdolsamad,Roshandel Gholamreza,Eslami Bita Archives of Iranian medicine BACKGROUND:The incidence and survival of breast cancer (BC) vary across countries. This study aimed to determine risk factors for BC and estimate the overall survival rate in BC patients of the Golestan Cohort Study (GCS). METHODS:This case-control study was performed among participants of the GCS. Cases (N = 99) consisted of women who were diagnosed with BC and controls (n = 400) were selected out of women participating in the same cohort and had not developed any cancer during the follow-up period. Controls were frequency matched to case on both place of residency and 5-year categories of age. RESULTS:Considering confounding variables, logistic regression analysis manifested a reverse association between parity and BC (OR [odds ratio] = 0.87, 95% CI: 0.80-0.95, P = 0.001). In addition, we found women who had family history of any cancer (OR = 1.63, 95% CI: 1.02-2.60, P = 0.04) and long term oral contraceptive (OCP) use (≥10 years) (OR = 3.17, 95% CI: 1.27-7.95, P = 0.01) were at higher risk of BC. Of the total patients, 23 (23.2%) were died due to BC after a mean follow-up of 102.4 ± 5.31 months. Using the Kaplan-Meier analysis, the 5-year survival in these patients was 74%. CONCLUSION:In the Golestan Cohort population, long term OCP use and family history of cancer were risk factors for BC, while parity was a protective factor. The 5-year survival of BC patients in the GCS is still lower relative to Europe and the United States.

Intervention and follow-up on human esophageal precancerous lesions in Henan, northern China, a high-incidence area for esophageal cancer. Wang Li Dong,Zhou Qi,Feng Chang Wei,Liu Bin,Qi Yi Jun,Zhang Yan Run,Gao Shan Shan,Fan Zong Min,Zhou Yun,Yang Chang S,Wei Jun Ping,Zheng Shu Gan to kagaku ryoho. Cancer & chemotherapy BACKGROUND:Esophageal cancer (EC) remains a leading cause of cancer-related deaths in Linzhou (formerly Linxian) and Huixian of Henan province, northern China, which has been well recognized as the highest incidence area for EC. The lack of useful chemoprevention agents and early detection methods is the key factors for stable EC incidence in these areas. Human esophageal carcinogensis has been considered as a multistep progressive process. The natural history for EC, however is not very clear. METHODS:Follow-up studies with linear repeated biopsies and histopathological examination were performed on 778 subjects from Linzhou and Huixian. Of these subjects, 578 subjects were followed for 11 years (1989-2000), 400 subjects with different severity of esophageal precancerous lesions were randomly divided into 2 groups for intervention studies with calcium and decaffeinated green tea (DGT). Each group included 200 subjects (100 subjects for treatment, and 100 subjects for placebo). In calcium group, each subject received an oral supplementation of 1,200 mg of calcium daily for 11 months. In DGT group, each subject received 5 mg of DGT daily for 12 months. In placebo group, each subject received placebo pill for 11 months (calcium group) and 12 month (DGT group). At the entry and the end of the trial, esophageal biopsy specimens were taken at the middle and the lower thirds of the esophagus and from macroscopic lesions, if only, of each subject. RESULTS:DGT trail did not show apparent difference between the treatment and placebo group in alleviating the esophageal precancerous lesions and abnormal cell proliferation. For the calcium intervention study, after 11 years' follow-up, 10 subjects had developed into cancers in the calcium group (10%, 8 EC and 2 GCA), and 8 subjects developed into EC in the placebo group (8%). All these patients were diagnosed at very early stage of cancer (symptom-free). Of the 578 subjects, 25 (18 males and 7 females) had developed into EC (n = 23, 4.3%) and gastric cardia cancer (GCA, n = 2, 0.3%), during the 11 years' follow-up. The mean time of cancer development (from entry of the follow-up study to the cancer detection) was 5.0 +/- 2.9 years (males) and 4.7 +/- 3.2 years (females). Of the 25 patients with EC and GCA, 11 were from the 387 followed subjects with "normal" histomorphology of biopsy at the entry of the follow-up study (3%, 11/387), 2 were from the subjects with basal cell hyperplasia, grade I (BCH I, 2%, 2/94), 7 from the subjects with BCH grade II (BCH II, 10%, 7/72), and 5 from BCH III and dysplasia (20%, 5/25). CONCLUSIONS:DGT trail was not shown to have beneficial effects in alleviating esophageal precancerous lesions and abnormal cell proliferation patterns. Calcium supplementation did not produce apparent long-term effects on EC. BCH II could be considered as precancerous lesions of EC. The quantitative histopathological analysis in terms of number of proliferating basal cell layers is of importance in determining the high-risk subjects for EC and evaluating the intervention results. Follow-up studies with repeated endoscopic biopsies are the powerful strategy for early detection and mortality control of EC and GAC in the high incidence area.
