RESUMEN
BACKGROUND & AIMS: Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Endoscopic eradication therapy (EET) can be effective in eradicating BE and related neoplasia and has greater risk of harms and resource use than surveillance endoscopy. This clinical practice guideline aims to inform clinicians and patients by providing evidence-based practice recommendations for the use of EET in BE and related neoplasia. METHODS: The Grading of Recommendations Assessment, Development and Evaluation framework was used to assess evidence and make recommendations. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients, conducted an evidence review, and used the Evidence-to-Decision Framework to develop recommendations regarding the use of EET in patients with BE under the following scenarios: presence of (1) high-grade dysplasia, (2) low-grade dysplasia, (3) no dysplasia, and (4) choice of stepwise endoscopic mucosal resection (EMR) or focal EMR plus ablation, and (5) endoscopic submucosal dissection vs EMR. Clinical recommendations were based on the balance between desirable and undesirable effects, patient values, costs, and health equity considerations. RESULTS: The panel agreed on 5 recommendations for the use of EET in BE and related neoplasia. Based on the available evidence, the panel made a strong recommendation in favor of EET in patients with BE high-grade dysplasia and conditional recommendation against EET in BE without dysplasia. The panel made a conditional recommendation in favor of EET in BE low-grade dysplasia; patients with BE low-grade dysplasia who place a higher value on the potential harms and lower value on the benefits (which are uncertain) regarding reduction of esophageal cancer mortality could reasonably select surveillance endoscopy. In patients with visible lesions, a conditional recommendation was made in favor of focal EMR plus ablation over stepwise EMR. In patients with visible neoplastic lesions undergoing resection, the use of either endoscopic mucosal resection or endoscopic submucosal dissection was suggested based on lesion characteristics. CONCLUSIONS: This document provides a comprehensive outline of the indications for EET in the management of BE and related neoplasia. Guidance is also provided regarding the considerations surrounding implementation of EET. Providers should engage in shared decision making based on patient preferences. Limitations and gaps in the evidence are highlighted to guide future research opportunities.

BACKGROUND & AIMS: Tools that can automatically predict incident esophageal adenocarcinoma (EAC) and gastric cardia adenocarcinoma (GCA) using electronic health records to guide screening decisions are needed. METHODS: The Veterans Health Administration (VHA) Corporate Data Warehouse was accessed to identify Veterans with 1 or more encounters between 2005 and 2018. Patients diagnosed with EAC (n = 8430) or GCA (n = 2965) were identified in the VHA Central Cancer Registry and compared with 10,256,887 controls. Predictors included demographic characteristics, prescriptions, laboratory results, and diagnoses between 1 and 5 years before the index date. The Kettles Esophageal and Cardia Adenocarcinoma predictioN (K-ECAN) tool was developed and internally validated using simple random sampling imputation and extreme gradient boosting, a machine learning method. Training was performed in 50% of the data, preliminary validation in 25% of the data, and final testing in 25% of the data. RESULTS: K-ECAN was well-calibrated and had better discrimination (area under the receiver operating characteristic curve [AuROC], 0.77) than previously validated models, such as the Nord-Trøndelag Health Study (AuROC, 0.68) and Kunzmann model (AuROC, 0.64), or published guidelines. Using only data from between 3 and 5 years before index diminished its accuracy slightly (AuROC, 0.75). Undersampling men to simulate a non-VHA population, AUCs of the Nord-Trøndelag Health Study and Kunzmann model improved, but K-ECAN was still the most accurate (AuROC, 0.85). Although gastroesophageal reflux disease was strongly associated with EAC, it contributed only a small proportion of gain in information for prediction. CONCLUSIONS: K-ECAN is a novel, internally validated tool predicting incident EAC and GCA using electronic health records data. Further work is needed to validate K-ECAN outside VHA and to assess how best to implement it within electronic health records.

BACKGROUND: The upper mediastinum is the most common metastatic site of esophageal squamous cell carcinoma (ESCC), and complete dissection of this region is important for oncologic reasons. This study aimed to compare the oncologic outcomes and completeness of upper mediastinal dissection for ESCC patients undergoing the Ivor-Lewis (IL) or McKeown (MK) operations. METHODS: Between 2013 and 2018, 680 patients (IL, 433; MK, 247) underwent upfront esophagectomy with two-field lymph node (LN) dissection for mid-to-lower ESCCs. Propensity score-matching (1:1 ratio) was performed to minimize the effects of confounding factors. RESULTS: The mean age was 64.5 ± 8.8 years, and 635 (93.4%) of the patients were male. The median follow-up period was 71.66 months (interquartile range [IQR], 59.60-91.04 months). The IL group had a higher mean age, lower body mass index, higher proportion of advanced T and N, and higher adjuvant therapy rates, but these differences were well-balanced after propensity score-matching. The mean number of dissected LNs at the mediastinum and at the right recurrent laryngeal nerve (RLN) were similar between the two groups after matching, whereas the IL group exhibited a slightly greater number of dissected LNs at the left RLN. Among the matched patients, the IL and MK groups exhibited similar 5-year overall survival (OS: 75.1% vs 78.0%; p = 0.368). The multivariate model showed no differences in OS, disease-free survival, or recurrence-free survival for locoregional, upper mediastinum, or neck between the two groups. CONCLUSIONS: This study suggests that both the IL and MK operations are oncologically feasible for patients with mid-to-lower ESCC.
RESUMEN
BACKGROUND: Obesity is associated with increased mortality in various cancers, but the relationship between obesity and clinical outcomes in unresectable or recurrent esophageal cancer who receive immune checkpoint inhibitors (ICIs) remains unknown. This study investigated the association between body composition and clinical outcomes in patients with unresectable or recurrent esophageal cancer who received ICIs. METHODS: Utilizing an unbiased database of 111 unresectable or recurrent esophageal cancers, we evaluated the relationships between body composition (body mass index, waist circumference, psoas major muscle volume, and subcutaneous and visceral fat areas) at the initiation of ICI treatment and clinical outcomes including the disease control rate and progression-free survival (PFS). RESULTS: Waist circumference was significantly associated with the disease control rate at the first assessment (P = 0.0008). A high waist circumference was significantly associated with favorable PFS in patients treated with nivolumab. In an univariable model, for 5-cm increase of waist circumference in the outcome category of PFS, univariable hazard ratio (HR) was 0.73 (95% confidence interval [CI], 0.61-0.87; P = 0.0002). A multivariable model controlling for potential confounders yielded a similar finding (multivariable HR, 0.56; 95% CI, 0.33-0.94; P = 0.027). We observed the similar finding in esophageal cancer patients treated with pembrolizumab+CDDP+5-FU (P = 0.048). In addition, waist circumference was significantly associated with the prognostic nutritional index (P = 0.0073). CONCLUSIONS: A high waist circumference was associated with favorable clinical outcomes in ICI-treated patients with unresectable or recurrent esophageal cancer, providing a platform for further investigations on the relationships among body composition, nutrition, and the immune status.

BACKGROUND: Dumping syndrome occurs frequently after esophageal cancer surgery, but the reported prevalence varied across previous studies. This systematic review and meta-analysis aimed to clarify the prevalence of dumping syndrome after esophageal cancer surgery, particularly exploring the sources of heterogeneity in previous studies. METHODS: A comprehensive literature search was conducted in PubMed, MEDLINE, Web of Science, Embase, and the Cochrane Library databases, supplemented by hand-search of reference lists, through March 2023. Random-effects meta-analysis estimated the average prevalence of dumping syndrome after esophageal cancer surgery. Heterogeneity across studies was examined by the I2 statistic and Cochran's Q test. RESULTS: Among the 2949 articles retrieved from the databases, 16 articles (15 cohort studies and 1 randomized controlled trial) met the inclusion criteria. The prevalence of dumping syndrome ranged 0-74% in these studies, showing high heterogeneity (I2 = 99%, P < 0.01), with the pooled prevalence of 27% (95% confidence interval [CI] 14-39%). The pooled prevalence in the three studies using specialized questionnaires was 67% (95% CI 60-73%), with reduced heterogeneity (I2 = 43%, P = 0.17). The prevalence also varied by year of publication, study population, and length and completeness of follow-up. CONCLUSIONS: Our findings revealed that dumping syndrome is common after esophageal cancer surgery. The varying prevalence across previous studies was probably owing to differences in measurement of dumping syndrome. Using specific patient reported outcome questionnaires is recommended for future investigations on dumping syndrome after esophageal cancer surgery.
RESUMEN
BACKGROUND: This study investigated the survival outcomes for surgically treated esophageal squamous cell carcinoma (ESCC) patients based on clinically suspicious supraclavicular lymph node (SCN) metastasis (cSCN+) and pathologically confirmed SCN metastasis (pSCN+). METHODS: Using an institutional registry between 1994 and 2018, this study retrospectively analyzed 611 patients who received curative-intent esophagectomy with 3-field lymph node dissection for ESCC. The study used computed tomography and positron emission tomography to define cSCN+. RESULTS: Among 611 patients, 24.4% had cSCN+ and 12.2% had pSCN+. The 5-year overall survival (OS) rates were 68.2% for cN0, 43.5% for cN+ without cSCN+, and 30.3% for cN+ with cSCN+ (p = 0.018). Although the univariable analysis showed that cSCN+ was associated with poorer survival than cN0 or cN+ with cSCN- (hazard ratio [HR], 1.818; p < 0.001), the multivariable analysis did not support this finding (HR, 1.281; p = 0.681). The 5-year OS rates were 64.2% for pN0, 41.5% for pN+ without pSCN+, and 25.6% for pN+ with pSCN+ (p = 0.054). Univariable analysis showed an association of pSCN+ with poor OS (HR, 1.830; p < 0.001), but the difference in the multivariable analysis was not significant (HR, 0.912; p = 0.587). CONCLUSIONS: The presence of SCN metastasis did not have a significant impact on the OS of ESCC patients with 3-field lymph node dissection regardless of clinical suspicion or pathologic confirmation.

BACKGROUND: Esophageal cancer brings emotional changes, especially anxiety to patients. Co-existing anxiety makes the surgery difficult and may cause complications. This study aims to evaluate effects of anxiety in postoperative complications of esophageal cancer patients with chronic obstructive pulmonary disease (COPD). METHODS: Patients with esophageal cancer and co-existing COPD underwent tumor excision. Anxiety was measured using Hospital Anxiety and Depression Scale (HAD) before surgery. Clavien-Dindo criteria were used to grade surgical complications. A multiple regression model was used to analyze the relationship between anxiety and postoperative complications. The chi-square test was used to compare the differences in various types of complications between the anxiety group and the non-anxiety group. A multinomial logistic regression model was used to analyze the influencing factors of mild and severe complications. RESULTS: This study included a total of 270 eligible patients, of which 20.7% had anxiety symptoms and 56.6% experienced postoperative complications. After evaluation by univariate analysis and multivariate logistic regression models, the risk of developing complications in anxious patients was 4.1 times than non-anxious patients. Anxious patients were more likely to develop pneumonia, pyloric obstruction, and arrhythmia. The presence of anxiety, surgical method, higher body mass index (BMI), and lower preoperative oxygen pressure may increase the incidence of minor complications. The use of surgical methods, higher COPD assessment test (CAT) scores, and higher BMI may increase the incidence of major complications, while anxiety does not affect the occurrence of major complications (P = 0.054). CONCLUSION: Preoperative anxiety is associated with postoperative complications in esophageal cancer patients with co-existing COPD. Anxiety may increase the incidence of postoperative complications, especially minor complications in patient with COPD and esophageal cancer.

Circulating tumor DNA (ctDNA) holds promise in resectable esophageal adenocarcinoma (EAC) to predict patient outcome but is not yet sensitive enough to be clinically applicable. Our aim was to combine ctDNA mutation data with shallow whole-genome sequencing (sWGS)-derived copy number tumor fraction estimates (ichorCNA) to improve pathological response and survival prediction in EAC. In total, 111 stage II/III EAC patients with baseline (n = 111), post-neoadjuvant chemoradiotherapy (nCRT) (n = 68), and pre-surgery (n = 92) plasma samples were used for ctDNA characterization. sWGS (<5× coverage) was performed on all time-point samples, and copy number aberrations were estimated using ichorCNA. Baseline and pre-surgery samples were sequenced using a custom amplicon panel for mutation detection. Detection of baseline ctDNA was successful in 44.3% of patients by amplicon sequencing and 10.5% by ichorCNA. Combining both, ctDNA could be detected in 50.5% of patients. Baseline ctDNA positivity was related to higher T stage (cT3, 4) (p = 0.017). There was no relationship between pathological response and baseline ctDNA positivity. However, baseline ctDNA metrics (variant allele frequency > 1% or ichorCNA > 3%) were associated with a high risk of disease progression [HR = 2.23 (95% CI 1.22-4.07), p = 0.007]. The non-clearance of a baseline variant or ichorCNA > 3% in pre-surgery samples was related to early progression [HR = 4.58 (95% CI 2.22-9.46), p < 0.001]. Multi-signal analysis improves detection of ctDNA and can be used for prognostication of resectable EAC patients. Future studies should explore the potential of multi-modality sequencing for risk stratification and treatment adaptation based on ctDNA results. © 2023 The Authors.

BACKGROUND: Postendoscopic submucosal dissection electrocoagulation syndrome (PEECS) is commonly observed after performing endoscopic submucosal dissection (ESD) for esophageal neoplasia. However, data on the incidence and risk factors for PEECS in the esophagus are lacking due to an unclear definition of PEECS and varied clinical settings. Therefore, we aimed to determine the risk factors for PEECS in patients undergoing ESD for esophageal neoplasia. METHODS: We retrospectively reviewed data of relevant clinical and endoscopy-specific parameters from 202 consecutive patients with esophageal neoplasias (139 carcinomas and 63 dysplasias) who underwent ESD under general anesthesia. Esophageal PEECS was defined by satisfying at least two of the following criteria: fever ≥ 37.8 °C, leukocytosis ≥ 10,800/mm3, and localized chest pain ≥ 5/10 points as assessed on a numeric rating scale within 24 h after ESD. Significant factors associated with PEECS were determined by regression analysis. RESULTS: PEECS was recorded in 98 of 202 (48.5%) patients. Patients with PEECS exhibited a larger tumor size (25.0 vs. 17.0 mm, P = 0.002), longer procedure (40.0 vs. 29.5 min, P = 0.021) and hemostasis times (5.0 vs. 3.5 min, P = 0.004), required greater submucosal injection volume (60.0 mL vs. 50.0 mL, P = 0.030), and had a lower rate of local steroid injection (4.1% vs. 12.5%, P = 0.029) than those without PEECS. Multivariate regression analysis revealed tumor size ≥ 17 mm (P = 0.047), procedure time ≥ 33 min (P = 0.027), and hemostasis time ≥ 5 min (P = 0.007) as risk factors for PEECS. In addition, local steroid injection was a significant negatively associated factor (P = 0.001). CONCLUSIONS: Patients with a large tumor, prolonged procedure and hemostasis times are at a high risk of PEECS occurrence. Further, local steroid injection is a negatively associated factor.

BACKGROUND: The real-world efficacy, feasibility, and prognostic factors of immune-checkpoint inhibitor combination therapy for unresectable or metastatic esophageal cancer are not fully established. METHODS: This multi-institutional retrospective cohort study evaluated 71 consecutive patients treated with immune-checkpoint inhibitor combination therapy for esophageal cancer between March 2021 and December 2022. We assessed tumor response, safety, and long-term survival. RESULTS: In patients with measurable lesions, the response rate was 58%, and the disease control rate for all enrolled patients was 80%. Five patients (7.0%) underwent successful conversion surgery. Grade 3 or higher immune-related adverse events occurred in 13% of patients, and one patient (1.4%) died due to cholangitis. Median progression-free survival was 9.7 (95% confidence interval: 6.5-not reached). C-reactive protein levels and performance status were identified as significant predictors of progression-free survival through Cox proportional hazards analysis. CONCLUSIONS: Immune-checkpoint inhibitor combination therapy for esophageal cancer demonstrated comparable tumor response, safety, and long-term survival to previous randomized clinical trials. Patients with good performance status and low C-reactive protein levels may be suitable candidates for this treatment.

BACKGROUND: To find a useful hypoxia non-invasive biomarker for evaluating early treatment response and prognosis to definitive chemoradiotherapy (dCRT) in patients with esophageal squamous cell carcinoma (ESCC), using blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI). METHODS: The R2* values were obtained pre- and 2-3 weeks post-dCRT in 28 patients with ESCC using BOLD MRI. Independent samples t-test (normality) or Mann-Whitney U test (non-normality) was used to compare the differences of R2*-related parameters between the complete response (CR) and the non-CR groups. Diagnostic performance of parameters in predicting response was tested with receiver operating characteristic (ROC) curve analysis. The 3-year overall survival (OS) was evaluated using Kaplan Meier curve, log rank test, and Cox proportional hazards regression analysis. RESULTS: The post-R2*, ∆R2*, and ∆%R2* in the CR group were significantly higher than those in the non-CR group (P = 0.002, 0.003, and 0.006, respectively). The R2*-related parameters showed good prediction of tumor response, with AUC ranging from 0.813 to 0.829. The 3-year OS rate in patients with ∆R2* >-7.54 s- 1 or CR were significantly longer than those with ∆R2* ≤ -7.54 s- 1 (72.37% vs. 0.00%; Hazard ratio, HR = 0.196; 95% confidence interval, 95% CI = 0.047-0.807; P = 0.024) or non-CR (76.47% vs. 29.27%; HR = 0.238, 95% CI = 0.059-0.963; P = 0.044). CONCLUSIONS: The preliminary results demonstrated that the R2* value might be a useful hypoxia non-invasive biomarker for assessing response and prognosis of ESCC treated with dCRT. BOLD MRI might be used as a potential tool for evaluating tumor oxygenation metabolism, which is routinely applied in clinical practice and beneficial to clinical decision-making. A large sample size was needed for further follow-up studies to confirm the findings.

Robotic esophagectomy has improved early outcomes and enhanced the quality of lymphadenectomy for esophageal cancer surgery. This study aimed to determine risk factors for long-term survival following robotic esophagectomy and the causes of long-term mortality. We included patients who underwent robotic esophagectomy at our institute between 2010 and 2022. Robotic esophagectomy was defined as a surgical procedure performed robotically in both the abdomen and thorax. Robotic esophagectomy was performed in patients at all stages, including advanced stages, even in patients with stage IV and supraclavicular lymph node metastasis. A total of 340 patients underwent robotic esophagectomy during the study period. Ivor-Lewis operation and McKeown operation were performed on 153 (45.0%) and 187 (55.0%) patients, respectively. The five-year survival rates based on clinical stages were as follows: 85.2% in stage I, 62.0% in stage II, 54.5% in stage III, and 40.3% in stage IV. Risk factors for long-term survival included body mass index, Charlson comorbidity index, clinical stages, and postoperative complications of grade 4 or higher. Among the cases of long-term mortality, recurrence accounted for 42 patients (61.7%), while non-cancer-related death occurred in 26 patients (38.2%). The most common cause of non-cancer-related death was malnutrition and poor general condition, observed in 11 patients (16.2%). Robotic esophagectomy has demonstrated the ability to achieve acceptable long-term survival rates, even in patients with cervical lymph node metastasis. However, addressing high-grade postoperative complications and long-term malnutrition remains crucial for further improving the long-term survival outcomes of patients with esophageal cancer.
RESUMEN
BACKGROUND: Recently, robot-assisted minimally invasive esophagectomy (RAMIE) has gained popularity worldwide. Some studies have compared the long-term results of RAMIE and minimally invasive esophagectomy (MIE). However, there are no reports on the long-term outcomes of RAMIE in Japan. This study compared the long-term outcomes of RAMIE and MIE. METHODS: This retrospective study included 86 patients with thoracic esophageal cancer who underwent RAMIE or MIE at our hospital from June 2010 to December 2016. Propensity score matching (PSM) was employed, incorporating co-variables such as confounders or risk factors derived from the literature and clinical practice. These variables included age, sex, body mass index, alcohol consumption, smoking history, American Society of Anesthesiologists stage, comorbidities, tumor location, histology, clinical TNM stage, and preoperative therapy. The primary endpoint was 5-year overall survival (OS), and the secondary endpoints were 5-year disease-free survival (DFS) and recurrence rates. RESULTS: Before PSM, the RAMIE group had a longer operation time (min) than the MIE group (P = 0.019). RAMIE also exhibited significantly lower blood loss volume (mL) (P < 0.001) and fewer three-field lymph node dissections (P = 0.028). Postoperative complications (Clavien-Dindo: CD ≥ 2) were significantly lower in the RAMIE group (P = 0.04), and postoperative hospital stay was significantly shorter than the MIE group (P < 0.001). After PSM, the RAMIE and MIE groups consisted of 26 patients each. Blood loss volume was significantly smaller (P = 0.012), postoperative complications (Clavien-Dindo ≥ 2) were significantly lower (P = 0.021), and postoperative hospital stay was significantly shorter (P < 0.001) in the RAMIE group than those in the MIE group. The median observation period was 63 months. The 5-year OS rates were 73.1% and 80.8% in the RAMIE and MIE groups, respectively (P = 0.360); the 5-year DFS rates were 76.9% and 76.9% in the RAMIE and MIE groups, respectively (P = 0.749). Six of 26 patients (23.1%) in each group experienced recurrence, with a median recurrence period of 41.5 months in the RAMIE group and 22.5 months in the MIE group. CONCLUSIONS: Compared with MIE, RAMIE led to no differences in long-term results, suggesting that RAMIE is a comparable technique.

INTRODUCTION AND AIMS: The outcomes of endoscopic submucosal dissection (ESD) in the esophagus have not been assessed in our country. Our primary aim was to analyze the effectiveness and safety of the technique. MATERIAL AND METHODS: Analysis of the prospectively maintained national registry of ESD. We included all superficial esophageal lesions removed by ESD in 17 hospitals (20 endoscopists) between January 2016 and December 2021. Subepithelial lesions were excluded. The primary outcome was curative resection. We conducted a survival analysis and used logistic regression analysis to assess predictors of non-curative resection. RESULTS: A total of 102 ESD were performed on 96 patients. The technical success rate was 100% and the percentage of en-bloc resection was 98%. The percentage of R0 and curative resection was 77.5% (n=79; 95%CI: 68%-84%) and 63.7% (n=65; 95%CI: 54%-72%), respectively. The most frequent histology was Barrett-related neoplasia (n=55 [53.9%]). The main reason for non-curative resection was deep submucosal invasion (n=25). The centers with a lower volume of ESD obtained worse results in terms of curative resection. The rate of perforation, delayed bleeding and post-procedural stenosis were 5%, 5% and 15.7%, respectively. No patient died or required surgery due to an adverse effect. After a median follow-up of 14months, 20patients (20.8%) underwent surgery and/or chemoradiotherapy, and 9 patients died (mortality 9.4%). CONCLUSIONS: In Spain, esophageal ESD is curative in approximately two out of three patients, with an acceptable risk of adverse events.

BACKGROUND: This retrospective study was performed to investigate the survival differences according to the pathologic status after neoadjuvant chemotherapy followed by surgery in esophageal squamous cell carcinoma (ESCC), and to investigate whether current AJCC 8th ypStage can predict survival accurately. METHODS: Data of 563 patients who received neoadjuvant therapy and esophagectomy for ESCC between 1994 and 2018 were retrospectively reviewed. RESULTS: The mean age was 62.00 ± 8.01 years, of which 524 (93.1%) were males. The median follow-up period was 29.12 months. A total of 153 (27.1%) patients showed pathologic complete response (pCR) and 92 (16.3%) patients showed pCR of the primary lesion with residual metastatic lymph nodes (ypT0N +). A total of 196 (35%) and 122 (21.6%) patients showed ypT + N + and ypT + N, respectively. The 5-year overall survival (OS) of each group was 75.1% (CR), 42.4% (ypT + N0), 54.9% (ypT0N +), and 26.1% (ypT + N +); CR patients showed better survival than the other groups, and no survival differences were found in the 5-year OS between ypT + N0 and ypT0N + patients (p = 0.811). In ypStage I, there were survival differences between ypT0N0 and ypTis-2N0 patients, and ypT1N0 (ypStage I) and ypT0N1 (ypStageIIIA) showed similar OS (5-year OS in 49.3% vs. 67.1%, p = 0.623). CONCLUSIONS: pCR offers long-term survival in patients; however, survival significantly declines with the presence of residual primary lesion and nodal metastases.

BACKGROUND & AIMS: Guidelines suggest endoscopic screening for esophageal adenocarcinoma (EAC) among individuals with symptoms of gastroesophageal reflux disease (GERD) and additional risk factors. We aimed to determine at what age to perform screening and whether sex and race should influence the decision. METHODS: We conducted comparative cost-effectiveness analyses using 3 independent simulation models. For each combination of sex and race (White/Black, 100,000 individuals each), we considered 41 screening strategies, including one-time or repeated screening. The optimal strategy was that with the highest effectiveness and an incremental cost-effectiveness ratio <$100,000 per quality-adjusted life-year gained. RESULTS: Among White men, 536 EAC deaths were projected without screening, and screening individuals with GERD twice at ages 45 and 60 years was optimal. Screening the entire White male population once at age 55 years was optimal in 26% of probabilistic sensitivity analysis runs. Black men had fewer EAC deaths without screening (n = 84), and screening those with GERD once at age 55 years was optimal. Although White women had slightly more EAC deaths (n = 103) than Black men, the optimal strategy was no screening, although screening those with GERD once at age 55 years was optimal in 29% of probabilistic sensitivity analysis runs. Black women had a very low burden of EAC deaths (n = 29), and no screening was optimal, as benefits were very small and some strategies caused net harm. CONCLUSIONS: The optimal strategy for screening differs by race and sex. White men with GERD symptoms can potentially be screened more intensely than is recommended currently. Screening women is not cost-effective and may cause net harm for Black women.

Esophageal squamous cell carcinoma (ESCC) is highly resistant to chemoradiation therapy. We aimed to examine whether Nutlin-3, a molecule that suppresses murine double min 2 (MDM2)-mediated p53 and Retinoblastoma (RB) protein degradation leading to downregulation of DNA methyltransferases (DNMTs), can be a novel therapeutic agent for ESCC. We used wild-type and chemoradiation-resistant ESCC cell lines in this study. The expression of DNMTs, p53 and RB, and methylation level of tumor suppressor genes (TSG) were analyzed upon Nutlin-3 treatment. The antitumor efficacy of Nutlin-3 was investigated in ESCC cell lines and xenograft tumor model. TSG protein expression was checked in the excised tumor tissue. Nutlin-3 induced upregulation of p53 and RB and downregulation of DNMTs proteins in the chemoradiation-resistant and aggressive ESCC cells. The methylation level of TSGs was decreased by Nutlin-3. Nutlin-3 inhibits clonogenic growth of ESCC cells and exerts a synergistic cytotoxic-effect when combined with chemotherapeutic agent cisplatin. Moreover, xenograft tumor growth in SCID mice was suppressed by Nutlin-3. The protein expression level of DNMTs was downregulated, and that of TSGs was upregulated by Nutlin-3 treatment in the excised tumor tissue. In conclusion, Nutlin-3 is a potential therapeutic agent that can potentiate the treatment efficacy of chemoradiation-resistant ESCC.

BACKGROUND: 4DCT (four-dimensional computed tomography) can effectively obtain functional lung ventilation images for patients and integrate them into radiotherapy treatment planning. Studies have not been performed on esophageal cancer, and there is no clear consensus on the optimal functional lung threshold for functional lung. METHODS: Functional lung images were generated for 11 patients with esophageal cancer. The correlation between the dose-volume parameters of functional lung (FL) as defined by different thresholds and the change of PFT/PDFT (pulmonary [diffusion] function test) metrics before and after radiotherapy were evaluated. FL-sparing planning was generated for each patient to preserve the functional lung and compared to conventional anatomical CT (non-sparing) planning. RESULTS: There was a significant positive correlation between the FL0.8 (defined Jacobian valueâ¯≤ 0.8), FL0.84, and FL0.9 dose-volume parameters and ΔFEV1/FVC (reduction before and after radiotherapy), and the FL0.8V30 correlation was the strongest (râ¯= 0.819, Pâ¯< 0.01). The FL-sparing planning had a target area conformity index and homogeneity index comparable to the non-sparing planning (Pâ¯> 0.05). For FL, the FL-sparing planning achieved lower FL-MLD (6.30⯱â¯2.14â¯Gy vs. 7.83⯱ 2.70â¯Gy), V10 (17.13⯱â¯7.70% vs. 27.40⯱ 9.48%), and V20 (6.96⯱â¯3.85% vs. 11.63⯱ 7.19%) compared to the non-sparing planning (Pâ¯< 0.05), while heart and spinal cord doses were not significantly different between the two planning groups. CONCLUSION: The 4DCT-based FL irradiation dose for esophageal cancer was significantly associated with a decrease in FEV1/FVC. The optimal FL defined as a Jacobian value ≤ 0.8 or about 21% of the whole lung volume may be a good choice. FL-sparing planning significantly reduced the FL dose without compromising target area coverage.

BACKGROUND: This study aimed to explore the association between drinking water source and risk of upper gastrointestinal (UGI) cancer, including esophageal cancer (EC) and gastric cancer (GC), in the Linxian General Population Nutrition Intervention Trial (NIT) cohort. METHODS: In this study, we used data from the Linxian NIT cohort, which included 29,584 healthy adults aged 40 to 69 years. Subjects were enrolled in April 1986 and followed up until March 2016. Tap water drinking status and demographic characteristics were collected at baseline. Subjects who drank tap water were treated as the exposed group. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using the Cox proportional hazard model. RESULTS: A total of 5,463 cases of UGI cancer were identified during the 30-year follow-up period. After adjusting for multiple factors, the incidence rate of UGI cancer in participants who drank tap water was significantly lower compared with individuals in the control (HR = 0.91, 95% CI: 0.86-0.97). A similar association was observed between tap water drinking and EC incidence (HR = 0.89, 95% CI: 0.82-0.97). The association between drinking tap water and risk of UGI cancer and EC incidence did not vary across the subgroup by age and gender (All Pinteraction > 0.05). For EC incidence, an interaction effect was observed for riboflavin/niacin supplements and drinking water source (Pinteraction = 0.03). No association was observed between drinking water source and GC incidence. CONCLUSIONS: In this prospective cohort study in Linxian, participants who drank tap water had a lower risk of EC incidence. As a source of drinking water, use of tap water may reduce the risk of EC by avoiding exposure to nitrate/nitrite. Measures should be taken to improve the quality of drinking water in high-incidence areas of EC. TRIAL REGISTRATION: The trial is registered with ClinicalTrials.gov (NCT00342654, 21/06/2006), and the trial name is Nutrition Intervention Trials in Linxian Follow-up Study.

OBJECTIVES: This study aimed to assess the efficacy of quantitative parameters derived from dual-energy computed tomography (DECT) for the preoperative prediction of early recurrence (ER) in patients with esophageal squamous cell carcinoma (ESCC). METHODS: In total, 78 patients with ESCC who underwent radical esophagectomy and DECT from June 2019 to August 2020 were enrolled in this study. Normalized iodine concentration (NIC) and electron density (Rho) in tumors were measured using arterial and venous phase images, whereas unenhanced images were used to determine the effective atomic number (Zeff). Univariate and multivariate Cox proportional hazards models were used to identify independent risk predictors of ER. Receiver operating characteristic curve analysis was performed using the independent risk predictors. ER-free survival curves were constructed using the Kaplan-Meier method. RESULTS: NIC in the arterial phase (A-NIC; hazards ratio [HR], 3.91; 95% confidence interval [CI], 1.79-8.56; p = 0.001) and pathological grade (PG; HR, 2.69; 95% CI, 1.32-5.49; p = 0.007) were identified as significant risk predictors of ER. The area under the curve of A-NIC for predicting ER in patients with ESCC was not significantly higher than that of PG (0.72 vs. 0.66, p = 0.441). In a stratified survival analysis, patients with high A-NIC or poorly differentiated ESCC had a higher rate of ER than those with low A-NIC or highly/moderately differentiated ESCC. CONCLUSIONS: A-NIC derived from DECT can be used to noninvasively predict preoperative ER in patients with ESCC, with an efficacy comparable to that of pathological grade. CLINICAL RELEVANCE STATEMENT: Preoperative quantitative measurement of dual-energy CT parameters can predict the early recurrence of esophageal squamous cell carcinoma and serve as an independent prognostic factor to guide clinical designation of personalized treatment. KEY POINTS: ⢠Normalized iodine concentration in the arterial phase and pathological grade were independent risk predictors of early recurrence in patients with esophageal squamous cell carcinoma. ⢠Normalized iodine concentration in the arterial phase may be a noninvasive imaging marker for preoperatively predicting early recurrence in patients with esophageal squamous cell carcinoma. ⢠The efficacy of normalized iodine concentration in the arterial phase derived from dual-energy computed tomography for predicting early recurrence is comparable to that of pathological grade.
