Background: Although endoscopic screening for esophageal cancer has been performed in high‐risk areas in China for decades, there is limited and inconsistent evidence regarding the starting age for individuals participating in screening. The aim of this study is to investigate the optimal starting age of esophageal cancer screening. Methods: This study is based on a multicenter prospective cohort consisting 338,017 permanent residents aged 40–69 years in six high‐risk areas of esophageal cancer in China. The participation rate, detection rate, hazard ratios (HRs), cumulative incidence and mortality and number needed to screen (NNS) were calculated in each age group. Screening burden, benefit and risk were compared among screening strategies with different initiation ages to explore the optimal starting age for population‐based screening in high‐risk areas. Results: Individuals aged 50–69 had a higher participation rate, a higher detection rate and improved screening effectiveness than those aged 40–49. The endoscopic screening had no significant effect on reducing the incidence of esophageal cancer in individuals under 55 and mortality in individuals under 45. Increasing the starting age to 50 years reduced the screening demand and NNS by 40% and 55%, and resulted in 12% of detectable positive cases, 16% of preventable incident cases, and 14% of preventable deaths being missed. Conclusions: Postponing the starting age of endoscopic screening to 50 years might yield a more‐favorable balance between screening benefit and burden in high‐ risk areas with limited resources.

Background: Dietary patterns and symptoms research among Chinese with esophageal squamous cell carcinoma (ESCC) and its precursor lesions is limited, especially as it relates to multiple food consumption and multiple co-occurring symptoms. The aim of our study was to identify the dietary patterns and severity of symptom classes with the risk of esophageal squamous cell carcinoma and its histological precursor lesions, and develop a risk prediction model for different stages of esophageal disease.Methods: We analyzed data from a multicenter cross-sectional study carried out in ESCC high incidence areas between 2017 and 2018, which included 34,707 individuals aged 40-69 years. Dietary patterns and severity of symptom classes were derived by applying a latent class analysis (LCA). A multiple logistic regression model was used to derive the odds ratio (ORs) and corresponding 95% confidence intervals (CIs) for ESCC and the different stages of esophageal disease according to the dietary patterns and severity of symptom classes identified. We built the risk prediction model by using a nomogram.Results: We identified five dietary patterns and three severity of symptom classes. The dietary patterns were classified as follows: "Healthy", "Western", "Lower consumers-combination", "Medium consumers-combination" and "Higher consumers-combination" patterns based on the intake of foods such as red meat, vegetables and fruits. The severity of symptoms was categorized into "Asymptomatic", "Mild symptoms" and "Overt symptoms" classes based on health-related symptoms reported by the participants. Compared to the "Healthy" pattern, the other four patterns were all associated with an increased risk of esophageal disease. Similarly, the other two symptom classes present different degrees of increased risk of esophageal disease compared to the "Asymptomatic". The nomograms reflect the good predictive ability of the model.Conclusion: Among individuals aged 40-69 years in high incidence regions of upper gastrointestinal cancer, the results supplied that subjects with diets rich in livestock and poultry meat and low in fruits and vegetables and subjects with typical symptoms were at increased ESCC risk. The findings highlight the importance of considering food and symptom combinations in cancer risk evaluation. [ABSTRACT FROM AUTHOR]

Background: Despite research efforts, the causative factors that contribute to esophageal squamous cell carcinoma (ESCC) in high-risk areas have not yet been understood. In this study, we, therefore, aimed to describe the risk factors associated with ESCC and its precursor lesions.Methods: We performed an endoscopic examination of 44,857 individuals aged 40-69 years from five high incidence regions of China in 2017-2018. Participants were classified as 4 groups of normal control, esophagitis, low-grade intraepithelial neoplasia (LGIN) and high-grade intraepithelial neoplasia/esophageal squamous cell carcinoma (HGIN/ESCC) using an unconditional logistic regression determine risk factors.Results: We identified 4890 esophagitis, 1874 LGIN and 437 HGIN/ESCC cases. Crude odds ratios (ORs) and adjusted odds ratios were calculated using unconditional logistic regression. Drinking well and surface water, salty diet, and positive family history of cancer were the common risk factors for esophagitis, LGIN and HGIN/ESCC. History of chronic hepatitis/cirrhosis was the greatest risk factor of esophagitis (adjusted OR 2.96, 95%CI 2.52-3.47) and HGIN/ESCC (adjusted OR 1.91, 95%CI 1.03-3.22). Pesticide exposure (adjusted OR 1.20, 95%CI 1.05-1.37) was essential risk factor of LGIN.Conclusions: Among individuals aged 40-69 years in high incidence regions of upper gastrointestinal cancer, the results provided important epidemiological evidence for the prevention of different precancerous lesions of ESCC.

Background: Long-term smoking exposure will increase the risk of esophageal squamous cell carcinoma (ESCC), whereas the mechanism is still unclear. We conducted a cross-sectional study to explore whether serum metabolites mediate the occurrence of ESCC caused by cigarette smoking.Methods: Serum metabolic profiles and lifestyle information of 464 participants were analyzed. Multiple logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of smoking exposure to ESCC risk. High-dimensional mediation analysis and univariate mediation analysis were performed to screen potential intermediate metabolites of smoking exposure for ESCC.Results: Ever smoking was associated with a 3.11-fold increase of ESCC risk (OR = 3.11, 95% CI 1.63-6.05), and for each cigarette-years increase in smoking index, ESCC risk increased by 56% (OR = 1.56, 95% CI 1.18-2.13). A total of 5 metabolites were screened as mediators by high-dimensional mediation analysis. In addition, glutamine, histidine, and cholic acid were further proved existing mediation effects according to univariate mediation analysis. And the proportions of mediation of histidine and glutamine were 40.47 and 30.00%, respectively. The mediation effect of cholic acid was 8.98% according to the analysis of smoking index.Conclusions: Our findings suggest that cigarette smoking contributed to incident ESCC, which may be mediated by glutamine, histidine and cholic acid.

Background: Evidence is required to quantify the population-level effects of endoscopic screening for esophageal squamous cell carcinoma (ESCC). The objective of this study was to evaluate the long-term effectiveness of 1-time endoscopic ESCC screening in a Chinese rural population.Methods: This community-based cohort study was based on an existing esophageal cancer screening program in Feicheng City, China. The screening group consisted of all permanent residents aged 40 to 69 years in 17 villages who were screened during 2006 through 2009, and the control group consisted of residents in another 43 villages who were not yet covered by the screening program. Residents in the remaining 511 villages were defined as the total population control. The cumulative incidence and mortality of ESCC and the observed and expected numbers of ESCC cases and deaths during the follow-up period (2010-2018) were calculated and compared.Results: After a 9-year follow-up, the screening group (n = 8460) revealed reductions of 20% (relative risk, 0.80; 95% CI, 0.66-0.97) and 32% (relative risk, 0.68; 95% CI, 0.52-0.89) in ESCC cumulative incidence and mortality, respectively, compared with the control group (n = 20,468). Endoscopic screening prevented 0.41% of the population (attributable risk, 0.41%; 95% CI, 0.07%-0.75%) from ESCC occurrence and 0.38% (attributable risk, 0.38%; 95% CI, 0.14%-0.62%) from ESCC-related death. In the screening group, reductions of 43% (standardized incidence ratio, 0.57; 95% CI, 0.48-0.67) and 45% (standardized mortality ratio, 0.55; 95% CI, 0.44-0.69) were found in the observed cumulative cases and deaths, respectively, compared with the expected cases and deaths.Conclusions: One-time endoscopic screening was associated with a significant and consistent reduction in ESCC incidence and mortality among individuals aged 40 to 69 years in high-risk areas.

Background: Endoscopic resection cap technique (ER-Cap), multiband mucosectomy (MBM), and endoscopic submucosal dissection (ESD) have been widely applied in the treatment of esophageal squamous neoplasia and cancer. However, little is known with regards to the comparison of these methods. This study aimed to compare the feasibility, safety, effectiveness, and costs of these three techniques. Methods: A retrospective analysis of patients with squamous premalignant or early malignant lesions of the esophagus undergoing ER-Cap, MBM, or ESD from January 2009 to December 2015 in one of the centers in China was performed. The procedural data and follow-up data for all patients were recorded. Results: A total of 672 patients with 733 lesions were included; 148 lesions (133 patients) were treated with ER-Cap, 427 lesions (388 patients) with MBM, and 158 lesions (151 patients) with ESD. The mean age was 61.59 years and the male-to-female ratio was 2.78:1. The operation time was significantly shorter for ER-Cap (29.26 ± 16.73 mins, p < 0.001) group, and the hospitalization costs were significantly lower in the MBM group (20,942.03 ± 8435.56￥, p = 0.003). The resection sample size of ESD was significantly larger (4.40 ± 1.20 cm, p < 0.001) and the en bloc resection rate of ESD was significantly higher (p < 0.001) than that of the other two groups. The frequencies of perforation, bleeding, and cicatricial stenosis were significantly lower in the MBM group (p < 0.001, p = 0.011, p = 0.009). Three local recurrences were observed in the ER-Cap group, while no recurrence was observed in MBM and ESD groups. There were three and two metastatic patients observed in the MBM and ESD groups, respectively. Conclusions: ER-Cap, MBM, and ESD are all minimally invasive, safe, and effective methods for treating early esophageal squamous cell carcinoma. MBM could be considered as a good alternative when performed by a less-experienced endoscopist in high-incidence areas with limited resources. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of the study was to examine health-related quality of life (HRQoL) about the most common cancers survivors (lung, stomach, colorectal, breast, and esophageal cancer) in rural China.Methods: We administrated a cross-sectional study in three counties in Shandong province from August to September 2017. The five-level EuroQol-5-dimension (EQ-5D-5L) questionnaire was used to measure the HRQoL among cancer patients at least 8 months post-diagnosis. The Chinese population-based preference trade-off time (TTO) model and discrete choice experiment (DCE) were used to convert the EQ-5D-5L utility score. Tobit regression model was used to identify independent associations between socio-demographic, clinical variables with the HRQoL.Results: In total, 452 cancer survivors were included. The mean EQ-5D-5L utility scores and Visual Analog Scale (EQ-VAS) scores were 0.841 (SD = 0.233) and 70.35 (SD = 18.80) for cancer survivors, respectively. Among the five dimensions, 58.6% of survivors had at least slight levels of pain/discomfort, and 39.2% showed at least slight levels of anxiety/depression. The influencing factors of HRQoL included cancer stage at diagnosis, tumor site, comorbidities, annual household income, and migrant worker status (rural-to-urban migration). Compared to other cancer patients, lung cancer patients had the lowest HRQoL. Higher household income and being a migrant worker were associated with a higher HRQoL for cancer survivors.Conclusions: Cancer survivors in rural China have deteriorated HRQoL, and a substantial number of survivors have pain/discomfort problems. Our study provides detailed data on HRQoL of rural cancer survivors for future supportive and survivorship care in China. [ABSTRACT FROM AUTHOR]
