Reporting National Outcomes After Esophagectomy and Gastrectomy According to the Esophageal Complications Consensus Group (ECCG)

OBJECTIVE: This nation-wide population-based study aimed to report postoperative morbidity and mortality after esophagectomy and gastrectomy in the Netherlands according to the definitions of the Esophagectomy Complications Consensus Group (ECCG). BACKGROUND: To standardize international outcome reporting in esophageal surgery, the ECCG developed a standardized outcomes set. METHODS: For this national cohort study, all patients undergoing esophagectomy or gastrectomy for cancer between 2016 and 2017 were selected from the Dutch Upper gastrointestinal Cancer Audit. In a random sample of hospitals, data completeness and accuracy were validated by reabstraction of the data. The investigated o

Intensive endoscopic therapy for untreated cervical anastomotic strictures after esophagectomy: a pilot study

Background Cervical anastomotic strictures after esophagectomy cause significant disease burden. We aimed to study the technical feasibility and safety of intensive endoscopic therapy. Methods In this pilot study, we included 15 patients with an untreated benign cervical anastomotic stricture after esophagectomy. Intensive endoscopic therapy comprised three endoscopic modalities: in- and excision using a needle-knife, intralesional steroid injections and bougie dilation. In two endoscopic procedures, the stricture was dilated up to a luminal diameter of 18 mm. Patients were followed up to 6 months. Results A luminal diameter of 18 mm was achieved in 13 of 15 patients (87%) after two endoscopic procedures. No major adverse events related to the investigational treatment occurred. Median dysphagia scores significantly improved from 2 (IQR, interquartile range, 2-3) at baseline to 0 (IQR 0-1) after 14 days (p < 0.001). Eleven (73%) patients developed recurrent symptoms of dysphagia requiring a median of 1 (IQR 0-3) additional endoscopic dilation procedure. Conclusions Achieving a luminal diameter of 18 mm in two procedures with intensive endoscopic therapy was technically feasible and effective in reducing dysphagia rapidly in patients with a cervical anastomotic stricture after esophagectomy. No major adverse events related to the investigational treatment were observed.Cellular mechanisms in basic and clinical gastroenterology and hepatolog

Incidence, Stage, Treatment, and Survival of Noncardia Gastric Cancer

Importance: Gastric cancer is the fifth most common cancer worldwide, and investigating its incidence, characteristics, treatment, and outcomes over the past decades can help in selecting clinical strategies and future research directions. Objective: To analyze the trends in incidence, staging, and treatment of gastric cancer. Design, Setting, and Participants: This nationwide, population-based cohort study included patients diagnosed with noncardia gastric cancer (NCGC) between 1989 and 2021 in the Netherlands. Main Outcomes and Measures: Differences in tumor characteristics, treatment, and survival were analyzed per fixed time periods (1989-1993, 1994-1998, 1999-2003, 2004-2008, 2009-2013, 2014-2018, and 2019-2021). Results: In total, 47 014 patients (median [IQR] age, 73 [64-80] years; 28 032 [60%] male patients) were identified with mostly adenocarcinomas of the antrum region (when location was known). Age-standardized incidence decreased from 20.3 to 6.1 per 100 000 person-years between 1989 and 2021. During the study period, unknown T and N stages were recorded less frequently, and metastatic disease was diagnosed more frequently (1989-1993: 2633 of 9493 patients [28%]; 2019-2021: 1503 of 3200 patients [47%] in 2019-2021). Over time, fewer patients with metastatic disease underwent surgery with or without other treatment modalities (68% in 1989-1993 vs 64% in 2019-2021), and palliative chemotherapy in metastatic NCGC increased from 9% to 40%. For patients with nonmetastatic disease, 5-year relative survival improved from 28% (95% CI, 26.5%-29.2%) to 36% (95% CI, 33.5%-37.6%) between 1989 and 2021. For patients with nonmetastatic disease undergoing a resection, 5-year survival increased from 40% (95% CI, 38.3%-41.8%) to 51% (95% CI, 47.9%-53.3%). For patients with metastatic disease, 1-year relative survival increased from 10% (95% CI, 8.7%-11.1%) to 19% (95% CI, 17.2%-21.6%), but 3-year relative survival remained poor at 5% (95% CI, 3.6%-7.5%). Conclusions and Relevance: In this nationwide cohort study involving 47 014 patients diagnosed with NCGC (1989-2021), the results showed a decrease in incidence, more accurate staging, a shift in treatment modalities, and improved patient survival.</p

Impact of Age and Comorbidity on Choice and Outcome of Two Different Treatment Options for Patients with Potentially Curable Esophageal Cancer

Purpose. This study was designed to assess the impact of age and comorbidity on choice and outcome of definitive chemoradiotherapy (dCRT) or neoadjuvant chemoradiotherapy plus surgery. Methods. In this population-based study, all patients with potentially curable EC (cT1N?/cT2-3, TX, any cN, cM0) diagnosed in the South East of the Netherlands between 2004 and 2014 were included. Kaplan–Meier method with log-rank tests and multivariable Cox regression analysis were used to compare overall survival (OS). Results. A total of 702 patients was included. Age C 75 years and multiple comorbidities were associated with a higher

A Population-based Study on Lymph Node Retrieval in Patients with Esophageal Cancer: Results from the Dutch Upper Gastrointestinal Cancer Audit

Background: For esophageal cancer, the number of retrieved lymph nodes (LNs) is often used as a quality indicator. The aim of this study is to analyze the number of retrieved LNs in The Netherlands, assess factors associated with LN yield, and explore the association with short-term outcomes. This is a population-based study on lymph node retrieval in patients with esophageal cancer, presenting results from the Dutch Upper Gastrointestinal Cancer Audit. Study Design: For this retrospective national cohort study, patients with esophageal carcinoma who underwent esophagectomy between 2011 and 2016 were included. The primary outcome was the number of retrieved LNs. Univariable and multivariable regression analyses were used to test for association with ≥ 15 LNs. Patients and Results: 3970 patients were included. Between 2011 and 2016, the median number of LNs increased from 15 to 20. Factors independently associated with ≥ 15 LNs were: 0–10 kg preoperative weight loss (versus: unknown weight loss, odds ratio [95% confidence interval]: 0.71 [0.57–0.88]), Charlson score 0 (versus: Charlson score 2: 0.76 [0.63–0.92]), cN2 category (reference: cN0, 1.32 [1.05–1.65]), no neoadjuvant therapy and neoadjuvant chemotherapy (reference: neoadjuvant chemoradiotherapy, 1.73 [1.29–2.32] and 2.15 [1.54–3.01]), minimally invasive transthoracic (reference: open transthoracic, 1.46 [1.15–1.85]), open transthoracic (versus open and minimally invasive transhiatal, 0.29 [0.23–0.36] and 0.43 [0.32–0.59]), hospital volume of 26–50 or > 50 resections/year (reference: 0–25, 1.94 [1.55–2.42] and 3.01 [2.36–3.83]), and year of surgery [reference: 2011, odds ratios (ORs) 1.48, 1.53, 2.28, 2.44, 2.54]. There was no association of ≥ 15 LNs with short-term outcomes. Conclusions: The number of LNs retrieved increased between 2011 and 2016. Weight loss, Charlson score, cN category, neoadjuvant therapy, surgical approach, year of resection, and hospital volume were all associated with increased LN yield. Retrieval of ≥ 15 LNs was not associated with increased postoperative morbidity/mortality
