Background: This study evaluated the association of pathological tumour response (tumour regression grade, TRG) and a novel scoring system, combining both TRG and nodal status (TRG-ypN score; TRG1-ypN0, TRG>1-ypN0, TRG1-ypN+ and TRG>1-ypN+), with recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma., Methods: This Dutch nationwide cohort study included patients treated with neoadjuvant chemoradiotherapy followed by oesophagectomy for distal oesophageal or gastro-oesophageal junctional adenocarcinoma between 2007 and 2016. The primary endpoint was the association of Mandard score and TRG-ypN score with recurrence patterns (rate, location, and time to recurrence). The secondary endpoint was overall survival., Results: Among 2746 inclusions, recurrence rates increased with higher Mandard scores (TRG1 30.6%, TRG2 44.9%, TRG3 52.9%, TRG4 61.4%, TRG5 58.2%; P < 0.001). Among patients with recurrent disease, the distribution (locoregional versus distant) was the same for the different TRG groups. Patients with TRG1 developed more brain recurrences (17.7 versus 9.8%; P = 0.001) and had a longer mean overall survival (44 versus 35 months; P < 0.001) than those with TRG>1. The TRG>1-ypN+ group had the highest recurrence rate (64.9%) and worst overall survival (mean 27 months). Compared with the TRG>1-ypN0 group, patients with TRG1-ypN+ had a higher risk of recurrence (51.9 versus 39.6%; P < 0.001) and worse mean overall survival (33 versus 41 months; P < 0.001)., Conclusion: Improved tumour response to neoadjuvant therapy was associated with lower recurrence rates and higher overall survival rates. Among patients with recurrent disease, TRG1 was associated with a higher incidence of brain recurrence than TRG>1. Residual nodal disease influenced prognosis more negatively than residual disease at the primary tumour site., (© The Author(s) 2024.

Objective: This study evaluated the nationwide trends in care and accompanied postoperative outcomes for patients with distal esophageal and gastro-esophageal junction cancer., Summary of Background Data: The introduction of transthoracic esophagectomy, minimally invasive surgery, and neo-adjuvant chemo(radio)therapy changed care for patients with esophageal cancer., Methods: Patients after elective transthoracic and transhiatal esophagectomy for distal esophageal or gastroesophageal junction carcinoma in the Netherlands between 2007-2016 were included. The primary aim was to evaluate trends in both care and postoperative outcomes for the included patients. Additionally, postoperative outcomes after transthoracic and tran-shiatal esophagectomy were compared, stratified by time periods., Results: Among 4712 patients included, 74% had distal esophageal tumors and 87% had adenocarcinomas. Between 2007 and 2016, the proportion of transthoracic esophagectomy increased from 41% to 81%, and neo-adjuvant treatment and minimally invasive esophagectomy increased from 31% to 96%, and from 7% to 80%, respectively. Over this 10-year period, postoperative outcomes improved: postoperative morbidity decreased from 66.6% to 61.8% ( P = 0.001), R0 resection rate increased from 90.0% to 96.5% (P <0.001), median lymph node harvest increased from 15 to 19 ( P <0.001), and median survival increased from 35 to 41 months ( P = 0.027)., Conclusion: In this nationwide cohort, a transition towards more neo-adju-vant treatment, transthoracic esophagectomy and minimally invasive surgery was observed over a 10-year period, accompanied by decreased postoperative morbidity, improved surgical radicality and lymph node harvest, and improved survival., Competing Interests: Luyer received research grants from Galvani and Medtronic.

Background: Anastomotic leakage is one of the most life-threatening complications after Ivor Lewis esophagectomy (ILE), with various treatment strategies. Endoscopic techniques are emerging as a less invasive alternative to surgery. Among the current endoscopic techniques, a single placement of an endoluminal nasogastric tube inside the cavity with controlled suction drainage (SD) seems to be an attractive option. The aim of this study was to evaluate the efficacy of SD as treatment for anastomotic leakage after ILE., Methods: This retrospective analysis was performed among patients who underwent ILE in a high-volume esophageal cancer center in the Netherlands. Patients with an anastomotic leakage that received SD as primary treatment were selected. A nasogastric tube was endoscopically placed into the cavity of the leakage for controlled suction with 15 mm Hg., Results: A total of 34 patients received SD and was successful in 26 patients (77%). Seven patients (21%) developed empyema despite the SD for which additional video-assisted thoracoscopic surgery was performed. Mortality was 5.9% (2 patients) and median intensive care unit and hospital stay were 3 days (1 to 9) and 25 days (14 to 43), respectively. The median time to closure of the leak was 41 days (23 to 65). A total of 16 patients underwent home treatment for a median of 23 (14 to 42) days., Conclusions: Controlled SD seems to be an effective treatment for anastomotic leakage after ILE. This therapy can safely and effectively be completed in an ambulant, outpatient setting., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: This study investigated the patterns, predictors, and survival of recurrent disease following esophageal cancer surgery., Background: Survival of recurrent esophageal cancer is usually poor, with limited prospects of remission., Methods: This nationwide cohort study included patients with distal esophageal and gastroesophageal junction adenocarcinoma and squamous cell carcinoma after curatively intended esophagectomy in 2007 to 2016 (follow-up until January 2020). Patients with distant metastases detected during surgery were excluded. Univariable and multivariable logistic regression were used to identify predictors of recurrent disease. Multivariable Cox regression was used to determine the association of recurrence site and treatment intent with postrecurrence survival., Results: Among 4626 patients, 45.1% developed recurrent disease a median of 11 months postoperative, of whom most had solely distant metastases (59.8%). Disease recurrences were most frequently hepatic (26.2%) or pulmonary (25.1%). Factors significantly associated with disease recurrence included young age (≤65 y), male sex, adenocarcinoma, open surgery, transthoracic esophagectomy, nonradical resection, higher T-stage, and tumor positive lymph nodes. Overall, median postrecurrence survival was 4 months [95% confidence interval (95% CI): 3.6-4.4]. After curatively intended recurrence treatment, median survival was 20 months (95% CI: 16.4-23.7). Survival was more favorable after locoregional compared with distant recurrence (hazard ratio: 0.74, 95% CI: 0.65-0.84)., Conclusions: This study provides important prognostic information assisting in the surveillance and counseling of patients after curatively intended esophageal cancer surgery. Nearly half the patients developed recurrent disease, with limited prospects of survival. The risk of recurrence was higher in patients with a higher tumor stage, nonradical resection and positive lymph node harvest., Competing Interests: M.D.P.L. received research grants from Galvani and Medtronic.

Background: The 5-year survival for patients with esophageal carcinoma remains poor despite neoadjuvant therapy and surgery. The eighth American Joint Committee on Cancer (AJCC) staging, based on the neoadjuvant treated TNM (ypTNM) stage of the resection specimen, is used for prognosis. Tumor characteristics such as tumor grade, subtype of adenocarcinoma, and tumor regression scores are not included in this classification. This study aimed to determine the impact of these tumor characteristics on overall survival (OS) and disease-free survival (DFS)., Methods: This retrospective cohort study included 228 patients with esophageal adenocarcinoma. Tumor regression was determined by the Mandard tumor regression (MTR) score. Subtype and grade of adenocarcinoma were confirmed using either the preoperative biopsy or residual tumor tissue after surgery. The MTR was modified to a three-tier classification. The study classified MTR 1 and 2 in one group as a "major response," with MTR 4 and 5 classified in one group as a "minimal response.", Results: The median follow-up period was 2.1 years. Combining MTR with AJCC staging did not improve the prognostic value for the prediction of OS. However, the multivariate analysis showed that the prognostic value of AJCC staging for DFS was improved by adding the three-tiered MTR (odds ratio for MTR4+5: 2.46; 95 % confidence interval, 1.07-5.67). Grade or subtype correlated with neither OS nor DFS in the univariate analyses and did not improve the prognostic value of the AJCC staging., Conclusion: Neither adenocarcinoma subtype nor grade influenced OS or DFS. However, the eighth AJCC staging combined with a three-tier MTR provided a better prognostic tool for DFS in esophageal adenocarcinoma treated with esophagectomy after neoadjuvant chemoradiotherapy., (© 2022.
