Incidence Rates Of Esophageal Cancer Research Articles

Spatial and temporal distribution characteristics research of esophageal cancer in China

Objectives: To explore the spatial distribution characteristics, trend changes, and spatial clustering of esophageal cancer among residents in China at the county (city, district) scale, a spatial epidemiological approach was used, with the aim of providing localized evidence for the prevention and treatment of esophageal cancer in China. Methods: The data source was the incidence (crude rate) and mortality (crude rate) of esophageal cancer from 2005 to 2016 in the 2008-2019 edition of China Cancer Registration Annual Report published by the National Cancer Center. The Joinpoint model was used for time trend analysis. The tumor registration area in 2016 was selected as the study area for spatial feature analysis, with a total of 487 counties (cities and districts), covering 27.6% of the national population. Spatial autocorrelation analysis was performed to reveal spatial distribution characteristics by using Arcgis 10.6 software, and spatial scanning statistics was used to analyze spatial clustering characteristics by using SaTScan 9.5 software. The log-likelihood ratio (LLR) and relative risk (RR) were calculated in different windows, and the region with the largest LLR value represented the most likely cluster. Results: From 2005 to 2016, the incidence and mortality rate of esophageal cancer in China showed a trend of increasing at first and then decreasing. The incidence and mortality rate of esophageal cancer in 2016 were characterized by spatial positive correlation. High incidence and high mortality were mainly concentrated in the areas through which the Huaihe River flowed. The primary clusters (taking high incidence rate as an example LLR=6 374.41, RR=2.37, P＜0.001) were mainly distributed in Jiangsu, Anhui and Shandong in eastern China and eastern Henan and southern Hebei in central China, and secondary clusters (taking high incidence rate as an example LLR=1 971.19, RR=1.91, P＜0.001) in Gansu, Ningxia Hui Autonomous Region, Shaanxi, Sichuan and other central and western regions. Conclusions: The incidence and mortality of esophageal cancer in China have decreased since 2010. The disease burden of esophageal cancer has obvious spatial differences, and measures should be taken according to local conditions in high-risk cluster areas such as the Huaihe River basin.

Genetic history of esophageal cancer group in southwestern China revealed by Y‐chromosome STRs and genomic evolutionary connection analysis

Genetic and environmental factors play crucial roles in the development of esophageal cancer (EC) and contribute uniquely or cooperatively to human cancer susceptibility. Sichuan is located in the interior of southwestern China, and the northern part of Sichuan is one of the regions with a high occurrence of EC. However, the factors influencing the high incidence rate of EC in the Sichuan Han Chinese population and its corresponding genetic background and origins are still poorly understood. Here, we utilized genome-wide single nucleotide polymorphisms (SNPs) and Y-chromosome short tandem repeats (Y-STRs) to characterize the genetic structure, connection, and origin of cancer groups and general populations. We generated Y-STR-based haplotype data from 214 Sichuan individuals, including the Han Chinese EC population and a control group of Han Chinese individuals. Our results, obtained from Y-STR-based population statistical methods (analysis of molecular variance (AMOVA), principal component analysis (PCA), and phylogenetic analysis), demonstrated that there was a genetic substructure difference between the EC population in the high-incidence area of northern Sichuan Province and the control population. Additionally, there was a strong genetic relationship between the EC population in the northern Sichuan high-incidence area and those at high risk in both the Fujian and Chaoshan areas. In addition, we obtained high-density SNP data from saliva samples of 60 healthy Han Chinese individuals from three high-prevalence areas of EC in China: Sichuan Nanchong, Fujian Quanzhou, and Henan Xinxiang. As inferred from the allele frequency of SNPs and sharing patterns of haplotype segments, the evolutionary history and admixture events suggested that the Han population from Nanchong in northern Sichuan Province shared a close genetic relationship with the Han populations from Xinxiang in Henan Province and Quanzhou in Fujian Province, both of which are regions with a high prevalence of EC. Our study illuminated the genetic profile and connection of the Northern Sichuan Han population and enriched the genomic resources and features of the Han Chinese populations in China, especially for the Y-STR genetic data of the Han Chinese EC population. Populations living in different regions with high incidences of EC may share similar genetic backgrounds, which offers new insights for further exploring the genetic mechanisms underlying EC.

Investigation on The Epidemic Dynamics of Esophageal Cancer and Changes in Dietary Structure of Residents in China

Write a summary and analysis of the pattern of changes in dietary structure and esophageal cancer risk factors in the Chinese population during the previous ten years. Analyze the association between the trend of esophageal cancer changes and dietary structure in the Chinese population by compiling statistics on the consumption of different foods by Chinese residents over the course of two time periods in the previous ten years. Residents' dietary patterns have changed significantly, with a rise in the consumption of beef, lamb, chicken, salt, and edible oil, while a decrease in the use of grains. The incidence rate and mortality of esophageal cancer have decreased in China over the past few decades, but the number of new cases and fatalities is gradually increasing. In order to reduce the occurrence of esophageal cancer, active intervention is needed to change residents' eating patterns. eating structure is intimately linked to the development of tube cancer.

Laryngo-Esophageal Dysfunction Free Survival of Chemoradiation for Cervical Esophageal Cancer

Chemoradiotherapy is often the treatment of choice for cervical esophageal cancer due to the invasiveness of surgery. However, toxicity after chemoradiotherapy often affects the quality of life related to swallowing and speech. This study evaluated laryngoesophageal dysfunction-free survival (LEDFS) in patients with cervical esophageal cancer, which has recently been used in head and neck cancer. We analyzed 59 patients with cervical esophageal cancer without distant metastases other than supraclavicular lymph node metastases who received radical chemoradiotherapy with 5-fluorouracilplus platinum between 2002 and 2018. Loco-regional control (LRC), overall survival (OS), LEDFS, metachronous esophageal cancer incidence rates, and late toxicities were evaluated. LEDFS events were defined as death, local recurrence, total or partial laryngectomy, tracheostomy for more than 2 years, and feeding tube use for more than 2 years, as recommended by the Larynx Preservation Consensus Panel. The Kaplan-Meier method was used to calculate survival rates. The generalized Wilcoxon test was used to compare the two groups. The Common Terminology Criteria for Adverse Events v5.0 was used to assess toxicities. The median age was 66 years (range, 38-83). There were 13 women and 46 men. Stage I, II, III, IVA, and IVB disease according to UICC 8th staging were 15, 9, 9, 10, and 16 patients, respectively. 22 received conventional radiotherapy and 37 received volumetric modulated arc therapy. The median total irradiation dose was 66 Gy. Platinum plus 5-fluorouracil chemotherapy was administered to all patients. The median follow-up for survivors was 87.5 months. The 5-year LRC, OS, and LEDFS rates were 54.2%, 48.9%, and 41.9%, respectively. The prognostic factors for OS were performance status (PS), hypopharyngeal extension, and clinical stage in univariate analysis and only clinical stage (hazard ratio [HR] 3.87, 95% Confidence interval [CI]: 1.52-9.87, p<0.01) in multivariate analysis; the prognostic factors for LEDFS were PS, hypopharyngeal extension and clinical stage in univariate analysis and hypopharyngeal extension (HR 2.38, 95% CI: 1.12-5.03, p = 0.02) and clinical stage (HR 4.07, 95% CI: 1.48-11.06, p<0.02) in multivariate analysis. Metachronous esophageal cancer was observed in 28.6% of patients at 5 years. As severe late toxicities, grade 3 pneumonitis, esophageal stricture, esophageal fistula, laryngeal stricture, and laryngeal edema were observed in 1 (2%), 1 (2%) and 4 (7%), 1 (2%) and 1 (2%), respectively. Grade 2 hypothyroidism was observed in 31 (53%) patients. Chemoradiation for cervical esophageal cancer showed good results. The prognostic factors for LEDFS were pharyngeal extension and clinical stage. Late esophageal and laryngeal toxicity, hypothyroidism, and metachronous esophageal cancer should be noted.

Environmental and life-style risk factors for esophageal squamous cell carcinoma in Africa: a systematic review and meta-analysis

BackgroundThe African Esophageal Squamous Cell Carcinoma (ESCC) corridor, which spans from Ethiopia down to South Africa, is an esophageal cancer hotspot. Disproportionately high incidence and mortality rates of esophageal cancer have been reported from this region. The aim of this study was to systematically assess the evidence on environmental and life-style risk factors associated with ESCC in African populations.MethodsWe followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and carried out a comprehensive search of all African published studies up to March 2023 using PubMed, Embase, Scopus, and African Index Medicus databases.ResultsWe identified 45 studies with measures of association [odds ratio (OR), relative risk (RR), and 95% confidence intervals (95%CI)], which reported on several environmental and lifestyle risk factors for ESCC in Africa. We performed a meta-analysis on 38 studies investigating tobacco, alcohol use, combined tobacco and alcohol use, polycyclic aromatic hydrocarbon exposure, hot food and beverages consumption (which served as a proxy for esophageal injury through exposure to high temperature), and poor oral health. We found significant associations between all the risk factors and ESCC development. Analysis of fruit and vegetable consumption showed a protective effect. Using population attributable fraction (PAF) analysis, we calculated the proportion of ESCC attributable to tobacco (18%), alcohol use (12%), combined tobacco and alcohol use (18%), polycyclic aromatic hydrocarbon exposure (12%), hot food and beverages intake (16%), poor oral health (37%), and fruit and vegetable consumption (-12%).ConclusionsTobacco smoking and alcohol consumption were the most studied risk factors overall. Areas where there is an emerging body of evidence include hot food and beverages and oral health. Concurrently, new avenues of research are also emerging in PAH exposure, and diet as risk factors. Our results point to a multifactorial etiology of ESCC in African populations with further evidence on prevention potential.

227. RELATIONSHIP BETWEEN 90-DAY PROGNOSIS NUTRITIONAL INDEX AND INFLAMMATORY RESPONSE MARKERS AND LONG-TERM SURVIVAL IN ESOPHAGEAL CANCER

Abstract Background The incidence rate of esophageal cancer in Asia is mainly squamous cell carcinoma, which is characterized by high mortality and poor prognosis. The prognosis of tumors is not only related to the biological characteristics of tumor cells, but also closely related to the nutritional status and inflammatory response of patients. The aim of this study is to investigate the relationship between nutritional index (PNI) and inflammatory response markers (NLR, LMR) at 90 days after surgery and long-term survival in patients with esophageal squamous cell carcinoma. To provide reference for accurately assessing the condition, identifying survival risks, and improving long-term prognosis. Methods The data of ESCC patients who underwent radical resection for esophageal cancer from April 2018 to November 2018 were extracted (n = 66). Calculate the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and other indicators of patients at 90 days after operation. ROC was used to calculate the cut-off values of PNI, NLR, and LMR. KaplanMeier survival curve was used to analyze the relationship between different PNI, NLR, LMR levels and long-term survival of patients. All patients were followed up regularly after surgery, and the last follow-up time was April 2023. Results The best cut-off values of PNI, NLR, and LMR were 42.8, 3.27, and 4.76, respectively. Kaplan Meier survival analysis showed a correlation between postoperative PNI, NLR, LMR at 90 days and overall survival and disease-free survival. At 90 days after surgery, the OS (P = 0.007) and DFS (P = 0.038) of patients in the high PNI group (PNI ≥ 42.8) were better than those in the low PNI group; The OS (P = 0.002) and DFS (P = 0.048) of patients in the low NLR group (NLR &amp;lt; 3.27) were better than those in the high NLR group; The OS (P = 0.001) and DFS (P = 0.039) of patients in the high LMR group (LMR ≥ 4.76) were better than those in the low LMR group. Conclusions PNI, NLR, and LMR are important predictors of OS and DFS in patients with esophageal squamous cell carcinoma after radical resection of esophagus. Patients with PNI ≥ 42.8, NLR&amp;lt;3.27, and LMR ≥ 4.76 at 90 days after surgery have better OS and DFS.

Trends in Epidemiology of Esophageal Cancer in the US, 1975-2018

Esophageal cancer (EC) is the 7th most common cancer worldwide and 14th in the US. More data are needed to study the changing incidence patterns of its 2 primary histologic subtypes, squamous cell carcinoma of the esophagus (SCE) and adenocarcinoma of the esophagus (ACE). To examine temporal trends in incidence rates of EC, ACE, and SCE from 1975 through 2018. In this population-based cross-sectional study, data were derived from 9 Surveillance, Epidemiology, and End Results (SEER) registries from January 1975 through December 2018 and from all 21 registries for January 2000 through December 2018 for patients with a diagnosis of EC from 1975 through 2018 (International Classification of Disease-Oncology, Third Edition codes). Age-adjusted incidence rates (AAIRs) of EC, ACE, and SCE were calculated. The timing and magnitude of the annual percentage change (APC) in incidence were examined using Joinpoint regression analyses. Data analysis was started in 2021 and updated and completed in 2023. The APC for age-adjusted EC incidence rates as stratified by histology, anatomical location, stage, sex, age, race and ethnicity, and geographic region. A total of 47 648 patients with a diagnosis of EC were retained for analysis. These included 22 419 (47.1%) with a diagnosis of SCE, 22 217 (46.6%) with ACE, and 3012 (6.3%) with other subtypes. The AAIR for EC changed from 4.14 per 100 000 population in 1975 to 4.18 in 2018, AAIRs of SCE declined from 3.06 in 1975 to 1.15 in 2018 as well as for ACE, and AAIRs increased from 0.42 in 1975 to 2.78 in 2018. From 1975 through 2004, EC incidence significantly increased (APC, 0.53; 95% CI, 0.4 to 0.7) but significantly decreased (APC, -1.03; 95% CI, -1.3 to -0.7) from then until 2018. The APC of SCE significantly continued to decline (-2.80, 95% CI, -3.0 to -2.6), and ACE increased from 2000 to 2006 (APC, 2.51; 95% CI, 1.0 to 4.0) but has since stabilized from 2006 to 2018. The results of this cross-sectional study suggest that the incidence of EC modestly declined since 2004 and that the incidence of SCE continued to decline while the incidence rate of ACE plateaued for more than a decade. Understanding factors associated with plateaued rates of ACE may help inform public health interventions.

Investigation of Some Possible Risk Factors for Esophageal Cancer in North Khorasan Province

Introduction: Northern part of Iran is located on the esophagus cancer belt worldwide, and North Khorasan province is considered a part of this region. This study was conducted to investigate some possible risk factors for esophageal cancer in North Khorasan province. Method: This cross-sectional study was based on esophageal endoscopy findings and histopathology reports. A total of 100 patients underwent endoscopy of whom 38 cases (19 male and 19 female) were diagnosed with esophageal cancer. Data consisted of age, gender, occupation, residential location, smoking, addiction history, education, food habits, hot tea consumption, lesion area, type of tissue, and alcohol consumption. The content and face validity of the questionnaire were investigated, followed by the evaluation of the reliability using Cronbach’s Alpha coefficient. Statistical analyses were performed using SPSS software (version 26). Results: The mean content validity index was 0.91, and Cronbach’s Alpha coefficient was obtained at 0.84. In this study, the highest incidence rates of esophageal cancer were in Bojnourd, Raz and Jargalan, Esfarayen, Maneh and Samolghan, Jajarm, and Shirvan in descending order. The mean age of patients with esophageal cancer was 66.36 years. The most common histological types of this cancer were related to squamous cell carcinoma (68.42%) and adenocarcinoma (28.94%), respectively. The distribution of esophageal carcinoma by anatomical location was 10.52% for the upper third, 26.31% for the middle third, and 63.15% for the distal third. Conclusion: It is necessary to monitor esophageal cancer continuously in North Khorasan province. This study suggests investigating how the recent pandemic of COVID-19 affects the epidemiology of esophageal cancer in the future

Patterns and trends in esophageal cancer incidence and mortality in China: An analysis based on cancer registry data

BackgroundEsophageal cancer poses a significant global burden, while its patterns and trends remain to be clarified. The aim of this study is to provide an update on the incidence and mortality rates of esophageal cancer and their trends in China based on data from the National Cancer Registry. MethodsWe extracted data from the National Central Cancer Registry (NCCR) of China from 2000 to 2016 and performed comprehensive quality control. We calculated age-standardized rates of China (ASR China) and world (ASR world) using the Chinese population in 2000 and the Segi's world standard population, and performed a joinpoint regression analysis to examine the trend in incidence and mortality of esophageal cancer. The annual percent change (APC) and weighted average APC (AAPC) over the entire study period were estimated to measure the changing trend. Subgroup analyses were conducted by sex, region and pathological type. ResultsA total of 487 eligible cancer registries were included in the data analysis and 22 registries with uninterrupted registration data were used for trend analysis. In 2016, there were an estimated of 184,500 incident cases of esophageal cancer and 142,300 deaths in China. The crude incidence, ASR China and ASR world were 25.25/100,000, 11.00/100,000 and 11.13/100,000, respectively. And the crude mortality, ASR China and ASR world were 19.38/100,000, 8.25/100,000 and 8.28/100,000, respectively. Esophageal squamous cell carcinoma (ESCC) was the most common histological type, accounting for 85.79% of all cases, followed by esophageal adenocarcinoma (EAC) (11.00%) and others (3.21%). There was a decreasing trend of ASR world in incidence and mortality during 2000–2016 with the AAPC of -4.6% (95% CI: -5.7%, -3.4%) and -4.6% (95% CI: -5.2%, -3.9%). The pattern and trend of esophageal cancer differ in sex, region and pathological type. ConclusionsThe burden of esophageal cancer in China remains high with sex, regional and subtype differences. The incidence and mortality of esophageal cancer have continued to decline over the past decade, which was due in part to the reductions in risk factor exposure and the implementation of screening.

Trends in Esophageal Adenocarcinoma and Esophageal Squamous Cell Carcinoma Incidence in the United States from 1992 to 2019.

Esophageal cancer (EC) incidence rates overall have declined in recent decades; however, the two main subtypes, esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), show divergent secular trends. Age-adjusted EC incidence rates were calculated using data from the Surveillance Epidemiology and End Results (SEER) 12 Program. We examined secular trends from 1992 to 2019 overall and by age group, sex, race/ethnicity, tumor location, and SEER registry. Joinpoint regression was used to compute annual percent changes (APC) and average annual percent changes (AAPC). We used age-period-cohort models to examine the potential impact of period and birth cohort effects on trends. Between 1992 and 2019, overall EC incidence rates declined by 0.54% annually (95% confidence interval [CI]: -0.75%, -0.33%). While ESCC rates declined linearly throughout the study period (AAPC = -2.85; 95%CI: -3.05%, -2.65%), EAC rates increased by over 5% annually from 1992 to 2000 (APC = 5.17; 95%CI: 3.28%, 7.10%), before stabilizing from 2000 to 2019 (APC = 0.22; 95%CI: -0.16%, 0.60%). Trends in ESCC and EAC varied by age group, sex, and race/ethnicity. Relative to ESCC rates among cohorts born circa 1950, the rates were 81% lower in cohorts born circa 1985 (rate ratio, 0.19; 95%CI: 0.04, 0.96). For EAC, rates have remained stable across successive birth cohorts since 1950. We observed linear declines in EC rates overall and for ESCC across age, sex, and race/ethnicity subgroups, but an inconsistent pattern for EAC. The trends in EAC cohorts born after 1955 were stable and suggest that EAC rates may have peaked in the U.S.

Mixed Neuroendocrine-Non-neuroendocrine Neoplasm (MiNEN) of the Esophagus: A Case Report

Esophageal cancer incidence rates have been increasing over the past years and survival rates remain low. According to the Global Cancer Observatory, 3.1% of new cancer cases consists of esophageal cancer and 5.5% of deaths was due to esophageal cancer. Histologic classification comprises of either squamous cell carcinoma (SCC) or Adenocarcinoma. Other types are reported to be uncommon. We present a case of 33-year old male admitted due to progressive dysphagia. He underwent esophagogastric resection and histopathologic studies revealed a mixed neuroendocrine- non-neuroendocrine tumor. He received adjuvant chemotherapy. On mid-cycle evaluation, the patient showed no evidence of disease recurrence.

Global burden of major gastrointestinal cancers and its association with socioeconomics, 1990-2019.

To understand the impact of common cancers of the gastrointestinal tract and help to formulate evidence-based policy, we evaluate the relationship between the burden of GI tract cancers and socioeconomics. Data on GI tract cancer burden were obtained from the Global Burden of Disease (GBD) 2019 including mortality and incidence rates. According to the Socio-demographic Index (SDI) level, country and territory, and sex, etc., the data were further stratified. The association between the burden of GI tract cancer and socioeconomics, indicated by SDI, was described. Uncertainty analysis was estimated using bootstrap draw. In 2019, five major cancers of the gastrointestinal tract led to an age-standardized incidence rate (ASIR) of 61.9 (95% CI 56.1-67.6) per 100 000 person-years. From 1990 to 2019, five common tumors of the gastrointestinal tract related age-standardized death rates (ASDRs) decreased by -22.7% (-31.1 to -13.5). For the five common tumors, ASIRs and ASDRs were both higher in males than those in females. Globally, Mongolia, and several East Asia countries exhibited the highest ASIRs in 2019. The high SDI, and high-middle SDI locations recorded the highest incidence rate and death rate of colon and rectum cancer and pancreatic cancer. On the contrary, the low-middle SDI, and low SDI locations possessed the highest incidence rate and death rate of stomach cancer and esophageal cancer. There is a profound association between socioeconomics and burden of common cancers of the gastrointestinal tract. It would be helpful for the high SDI, and high-middle SDI locations to pay special attention to the screening of colon and rectum cancer and pancreatic cancer while the low-middle SDI, and low SDI locations should pay more attention to the screening of stomach cancer and esophageal cancer.

Chinese expert consensus on early diagnosis and treatment of esophageal cancer

Although the incidence rate of esophageal cancer in China is on the decline, China is still a high-incidence country of esophageal cancer with great regional variation. In recent years, the five-year survival of esophageal cancer in China has improved significantly. However, due to the absence of typical symptoms in early stage, there still exists a large esophageal cancer diagnostic yield gap between China and developed countries. At present, there are no international guidelines defining the target population for esophageal squamous cell carcinoma (ESCC) screening. Exploring and implementing effective esophageal cancer screening together with early diagnosis and early treatment are the keys to reducing the mortality and improving the survival rate and life quality. Endoscopic therapies, such as endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR), and radiofrequency ablation (RFA), are used to treat early-stage esophageal cancer. If the tumor invasion is deep or lymph node metastasis is suspected, surgery is needed, meanwhile radiation therapy could also be an optional treatment. Regular follow-up and surveillance are required for any strategy above to deal with relapse and metachronous primary cancers. The Early Diagnosis and Treatment Group of the Chinese Medical Association Oncology Branch has reached an expert consensus on screening and diagnostic protocols for esophageal cancer, on endoscopic and surgical treatment of early esophageal cancer and precancerous lesions, as well as on postoperative monitoring and adjuvant therapy. This consensus follows the evidence-based medicine at both domestic and international levels, combines the current clinical practice and application experience in the treatment of esophageal cancer in China, is based on a multidisciplinary treatment model, and can be used as a reference for clinicians.

S398 Dramatic Stabilization of Trend of Esophageal Adenocarcinoma (EAC) in the United States: A Population-Based Time-Trend Analysis of Surveillance, Epidemiology and End Results Program Database (SEER), 2001-2018

Introduction: Prior studies showed that EAC had dramatically increased by 611% from 1973 to 2001. Therefore, the aim of this study was to determine the recent incidence trends of EAC by histopathology in the United States from 2000-2018 using the SEER database. Methods: Incidence rates of esophageal cancer per 100,000 population (age-adjusted to the 2000 US population) from 2000 to 2018 were calculated from the SEER 21 database using SEER*Stat software (v8.4.1, National Cancer Institute (NCI). Esophageal cancer was defined as any cancer located within the esophagus, and the histopathology subtypes were grouped as EAC or squamous cell cancer (SCC) based on ICD-O-3 Codes (Table). Time-trends reported as annual percentage change (APC) and average APC (AAPC) were quantified by Joinpoint Regression Program (v4.9.0.1, NCI), utilizing Monte Carlo permutation analysis to identify the best fit. A 2-tailed t-test was utilized to access statistical significance (p-value < 0.05). Pairwise comparison between the segmented-linear trends was performed to test parallelism and identicalness of the trends. Results: A total of 103,117 (79% male) patients were diagnosed with esophageal cancer from 2000-2018. Of those, 58,782 were diagnosed with EAC while 34,084 were diagnosed with SCC (Table). The overall incidence rate of esophageal cancer was found to be stable from 2000-2004 [APC 0.37% (95% CI, -1.32-2.07%)] but significantly decreased from 2004-2018 [APC -1.24% (95% CI, -1.48% - -1.01%)]. In SCC, the trend has shown a consistent decrease in incidence rate from 2000-2018 [APC -2.81% (95% CI, -3.03% - -2.59%)]. EAC trends showed two joinpoints. with a peak incidence noted in 2007 (Table and Figure). Despite slight variation in trends across joinpoints , the overall trend of EAC incidence was not statistically significant and therefore stable over this time period [0.61% (95% CI, -0.30% - 1.53%)], p-value = 0.19. The trends between the histopathology groups of EAC and SCC, were not identical nor parallel (p-value < 0.001), showing that the trends between these two groups differed from one another. Conclusion: While previous studies showed a >600% increase in incidence of EAC from 1973 to 2001, our updated large population-based study, covering more than a third of the US population, shows a dramatically improved stable trend from 2000 to 2018. Future studies should evaluate the impact of proton pump inhibitor use and endoscopic therapies on these trends.Figure 1.: Age-Adjusted Incidence Rates Per 100,000 Population for Esophageal Cancer A: The incidence of esophageal cancers significantly decreased [AAPC -0.89% (95% CI, -1.26%- -0.51%)] while the incidence of EAC had 3 varying segments of incidence rate: 2000 to 2008 had an increase [APC 2.13% (95% CI, 1.46% - 2.80%)], 2008-2011 had a decrease [APC -3.05% (95% CI, -8.34% - 2.54%)] and 2011 to 2018 had a stable trend [APC 0.49% (95% CI, -0.23% - 1.21%)]. B: The incidence of SCC consistently decreased [APC -2.81% (95% CI, -3.03% - -2.59%)] C: The incidence of EAC and SCC were not identical nor parallel (both p-value < 0.001).

An Introduction to Home Care for Esophageal Cancer

Esophageal cancer is a common tumor of the digestive tract and is a malignant tumor which affect one’s health and is potentially life threatening. The incidence and mortality rate of esophageal cancer in China is relatively high, with the incidence rate being the sixth highest and the mortality rate being the fourth highest among all malignant tumors. The lesion often occurs in the middle segment of the epithelium of the esophagus, often showing a family tendency, and is more likely to occur in middle-aged and elderly men. The typical symptom of esophageal cancer is progressive dysphagia, first with dry food, then with semi-liquid food, and finally with water and saliva. Treatment is divided into surgical treatment, radiotherapy, chemotherapy, and combination therapy. Apart from malnutrition and pain, the treatment can also cause great psychological stress to patients with esophageal cancer. Therefore, diet, pain, and psychological care for patients with esophageal cancer are crucial. Therefore, it more care is given to the patients by medical and nursing staff during hospitalization. However, not much have been discussed about home care for patients with esophageal cancer. In this article, we will talk about the home care of esophageal cancer patients from the following aspects: dietary, pain management, and psychological care.

Impact of Medicaid Expansion on Incidence and Mortality from Gastric and Esophageal Cancer.

Individuals in Medicaid expanded states have increased access to treatment for medical conditions and other health care resources. Esophageal and gastric cancer are associated with several modifiable risk factors (e.g. smoking, drinking, Helicobacter pylori infection). The impact of Medicaid expansion on these cancers incidence and mortality remains uninvestigated. We evaluated the association between Medicaid expansion and gastric and esophageal cancer incidence and mortality in adults aged 25-64. We employed an observational design using a difference-in-differences method with state level data, from 2010 to 2017. Annual, age-adjusted gastric and esophageal cancer incidence and mortality rates, from the CDC Wonder Database, were analyzed. Rates were adjusted for by several socio-demographic factors. Expansion and non-expansion states were similar in percent Hispanic ethnicity and female gender. The non-expansion states had significantly higher proportion of Black race, diabetics, obese persons, smokers, and those living below the federal poverty line. Adjusted analyses demonstrate that expansion states had significantly fewer new cases of gastric cancer: -1.6 (95% CI 0.2-3.5; P = 0.08) per 1,000,000 persons per year. No significant association was seen between Medicaid expansion and gastric cancer mortality (0.46 [95% CI -0.08 to 0.17;P = 0.46]) and esophageal cancer incidence (0.8 [95% CI -0.08 to 0.24; P = 0.33]) and mortality (1.0 [95% CI -0.06 to 0.26; P = 0.21]) in multivariable analyses. States that adopted Medicaid expansion saw a decrease in gastric cancer incidence when compared to states that did not expand Medicaid. Though several factors may influence gastric cancer incidence, this association is important to consider during health policy negotiations.

Urinary nitrate and sodium in a high-risk area for upper gastrointestinal cancers: Golestan Cohort Study☆

BackgroundThe epidemiological evidence regarding the carcinogenicity of nitrate and sodium in drinking water is limited, partly because measuring the exposure at the individual level is complex. Most studies have used nitrate in water supplies as a proxy for individual exposure, but dietary intakes and other factors may contribute to the exposure. The present study investigates the factors associated with urinary nitrate and sodium in a high-risk area for esophageal and gastric cancers. MethodsFor this cross-sectional study, we used data and samples collected in 2004–2008 during the enrollment phase of the Golestan Cohort Study from a random sample of 349 participants (300 individuals from 24 rural villages and 49 from the city of Gonbad), stratified by average water nitrate in their district, the source of drinking water, and the usual dietary intake of nitrate and sodium. Nitrate, sodium, and creatinine were measured in a spot urine sample collected at the time of interview. We used the provincial cancer registry data to calculate the cumulative incidence rates of esophageal and gastric cancers for each location through June 1, 2020, and used weighted partial Pearson correlation to compare the incidence rates with median urinary nitrate and sodium in each village or the city. ResultsAmong 349 participants (mean age±SD: 50.7 ± 8.6 years), about half (n = 170) used groundwater for drinking, and the use of groundwater was significantly more common in high-elevation locations (75.8%). The geometric mean of the creatinine-corrected urinary nitrate concentration was 68.3 mg/g cr (95%CI: 64.6,72.3), and the corresponding geometric mean for urinary sodium was 150.0 mmoL/g cr (95%CI: 139.6,161.1). After adjusting for confounders, urinary nitrate was associated with being a woman, drinking groundwater, and living in high-elevation locations, but not with estimated dietary intake. Urinary sodium concentration was significantly associated with monthly precipitation at the time of sampling but not with elevation or drinking water source. There were significant positive correlations between both median urinary nitrate and sodium in each location and esophageal cancer incidence rates adjusted for sex and age (r = 0.65 and r = 0.58, respectively, p < 0.01), but not with gastric cancer incidence. ConclusionIn a rural population at high risk for esophageal and gastric cancers, nitrate excretion was associated with living at a higher elevation and using groundwater for drinking. The associations between nitrate and sodium excretion with esophageal cancer incidence warrant future investigation.

International trends in esophageal cancer incidence rates by histological subtype (1990-2012) and prediction of the rates to 2030.

We provide an up-to-date overview of recent international trends (1990-2012) and predicted trends (2013-2030) in the incidence rates of esophageal cancer. We used data from the Cancer Incidence in Five Continents (CI5plus) database that contains annual incidence data by cancer site, age, and sex as well as corresponding populations. The age-standardized esophageal cancer incidence rates of each country were calculated and plotted from 1990 through 2012 and were predicted to 2030 using a Bayesian age-period-cohort model. Globally, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) showed opposing trends between 1990 and 2012; ESCC showed a decreasing trend, with an AAPC of -1.5 (95% CI -2.4, -0.7), yet EAC showed an increasing trend, with an AAPC of 5.2 (95% CI 4.2, 6.2). The increasing trend in EAC was commonly observed in high-income countries. The predicted trend to 2030 indicated that most countries will continue to experience a decreasing trend or a stable trend in esophageal cancer incidence, except Denmark, the Netherlands, and the UK, where the overall esophageal cancer incidence rates, mainly driven by EAC, are predicted to increase. Decreasing trends in ESCC have been observed worldwide in both low- and middle-income countries and high-income countries, which may have been offset by increasing trends in EAC in high-income countries. The changing patterns of these two main subtypes of esophageal cancer may call for interventions, especially innovative interventions, to address obesity, GERD, and Barrett's esophagus.

P-251 Outcomes in patients with locally advanced esophageal cancer after neoadjuvant concurrent chemoradiation: A retrospective study from low- to middle-income countries

Esophageal cancer is a highly aggressive tumor often associated with poor prognosis. Globally the incidence and prevalence rates of esophageal cancer vary a lot. Genetic and phenotypic variations in different populations have variable survival outcomes. Concurrent chemoradiation as per Cross Trial is standard of care and now being widely used in Pakistan, however there is scarcity of data in our population. This study aims at identifying the disease-free survival of patients treated with Cross trial in our tertiary care institute.

Racial and ethnic disparities in incidence and mortality for the five most common gastrointestinal cancers in the United States

BackgroundGastrointestinal cancers account for a significant burden of cancers in the United States. We sought to measure relative incidence of and mortality from the five most common gastrointestinal malignancies by race and ethnicity. MethodsWe used data from the National Cancer Institute Surveillance, Epidemiology, and End Results Cancer Registry and the National Center for Health Statistics to calculate incidence and mortality rates for colorectal, pancreatic, liver, esophageal, and gastric cancer from 2013 to 2017 (incidence) and 2014 to 2018 (mortality). We then calculated incidence and mortality rate ratios, comparing each racial/ethnic group (non-Hispanic Black, non-Hispanic Asian/Pacific Islander, non-Hispanic American Indian/Alaska Native, and Hispanic) to non-Hispanic White. ResultsColorectal cancer had highest overall incidence and mortality. When compared to non-Hispanic White individuals, all other racial/ethnic groups had significantly higher incidence of liver and gastric cancer but lower incidence of esophageal cancer. Non-Hispanic Black individuals had higher incidence of colorectal and pancreatic cancer than non-Hispanic White individuals, while Hispanic and non-Hispanic Asian/Pacific Island individuals had lower incidence of these two cancers compared to non-Hispanic White individuals. Disparity patterns were similar for mortality. ConclusionsLiver and gastric cancer have the greatest differences in incidence and mortality by race/ethnicity. Non-Hispanic Black individuals carry the highest burden of gastrointestinal malignancies overall.
