  • The Impact of Anastomotic Leak After Esophagectomy on Long-term Survival in the Modern Era of Management (ALES Study)

    by Lorenzo Giorgi, Nadia Guidozzi, Riadh Salem, Wing K. Chou, Stijn Vanstraelen, Helena Gielen, Johnny Moons, Philippe Nafteux, Femke E. Lammes, Jelle P. Ruurda, et al.

    Objective: To determine the impact of severity of esophageal anastomotic leak (AL), standardized by ECCG grading, on long-term survival within a contemporary multicenter cohort. Summary Background data: Historical evidence suggesting AL is associated with increased recurrence and poor survival is limited by heterogeneous definitions and outdated management. This study utilizes the standardized ECCG definition to evaluate the prognostic significance of AL severity under modern perioperative protocols and endoscopic rescue strategies. Methods: An international multicenter cohort across 17 high-volume European centers. Adult patients with esophageal or junctional cancer treated with neoadjuvant CROSS or FLOT, followed by esophagectomy were included (2018–2023). Results: Out of 2905 patients, 425 (14.6%) developed an AL. AL was associated with a nearly two-fold increase in pulmonary complications (46.8% vs. 26.7%; P P P P =0.029). A lower rate of adjuvant therapy administration (33.9% vs. 43.3%; P =0.004) was observe for AL patients. No significant survival deficits were observed for leaks treated conservatively or with no-surgical intervention. Conclusions: AL requiring surgical reintervention was associated with impaired survival. This relationship identifies a high-risk clinical profile and represents a critical target for future research into strategies for clinical stabilization and risk mitigation.

  • The Prognostic Impact of Lymph Node Yield Upon Survival in Esophageal Cancer Broken Down by Neoadjuvant Strategy

    by Nadia Guidozzi, Wing K. Chou, Lorenzo Giorgi, Riadh Salem, Stijn Vanstraelen, Helena Gielen, Johnny Moons, Philippe Nafteux, Femke E. Lammes, Jelle P. Ruurda, et al.

    Objective: To establish a lymph node yield (LNY) change-point associated with improvements in overall survival (OS) and disease-free survival (DFS) in patients undergoing esophagectomy following neoadjuvant treatment for esophageal adenocarcinoma. Secondary endpoints include recurrence patterns and survival based on pathological staging. Summary Background Data: LNY has been associated with improved outcomes in esophageal cancer. The extent of lymphadenectomy following neoadjuvant treatment remains unclear. Methods: This multicenter European study included patients undergoing chemotherapy (CT) or chemoradiotherapy (CRT) followed by esophagectomy between 2018 and 2023. RA-CUSUM analysis identified change points between LNY and survival. Bootstrap resampling determined the optimal LNY, and multivariable Cox proportional hazards models analyzed LNY as continuous and categorical variables. A post hoc exploratory subgroup analysis was conducted in CT patients with optimal LNY compared with CRT irrespective of LNY. Recurrence patterns were assessed using the Fisher exact test. Results: A total of 2069 patients were included: 957 CT versus 1112 CRT. Median LNY was 32. CT data set: an optimal threshold of 25 nodes was identified (95% CI: 20–39). Categorical analysis using ≥25 nodes demonstrated 29% mortality reduction (HR: 0.714, P =0.0017). CRT data set: no significant LNY association across any endpoint. Continuous LNY showed a null effect ( P =0.633), and categorical analysis showed no benefit ( P =0.66). CT with ≥25 LNY had ∼44% lower mortality compared with CRT after adjustment for potential confounding variables (HR=0.563, P P =0.001). Conclusion: On the basis of this data, there is a clear survival and recurrence benefit to performing a radical lymphadenectomy with a lymph node harvest of at least 25 nodes in patients who have received CT.

  • Etude de l’association du microbiote intestinal et des caractéristiques de composition corporelle sur les résultats postopératoires du cancer colorectal sporadique non métastatique

    by Julie Veziant

    La chirurgie représente encore le principal traitement à visée curative du cancer colorectal (CCR). Les complications postopératoires, majoritairement représentées par la fistule anastomotique (FA), les infections de site opératoire (ISO) et l’iléus postopératoire prolongé (IPOP), sont responsables d’une altération de la qualité de vie des patients, d’un surcoût des soins de santé hospitaliers et de survie potentiellement réduite du fait d’un retard à l’administration d’une chimiothérapie adjuvante. La morbidité postopératoire reste élevée, évaluée entre 30 et 35% selon le dernier rapport de l’Association Française de Chirurgie. Des facteurs de risques liés au patient ou à l’acte chirurgical (modifiables ou non) ont été identifiés dans la littérature scientifique. Les cliniciens suggèrent l’utilisation de l’analyse tomodensitométrique de la composition corporelle (masse grasse et musculaire squelettique) comme nouvel indicateur pronostique dans le CCR. Une autre approche émergente consiste à considérer l’impact du microbiote intestinal (MI) sur l’efficacité des thérapies anti-tumorales comme la chirurgie, la (radio)chimiothérapie et l’immunothérapie. A ce jour, très peu d’études cliniques se sont intéressées à l’influence du MI sur les suites opératoires après chirurgie à visée curative du CCR. L’objectif de ce travail était d’étudier la valeur prédictive du MI et des caractéristiques de composition corporelle sur les complications postopératoires du CCR.Ce travail de thèse rapporte le cheminement de l’étude clinique METABIOTE (NCT03843905) depuis sa mise en place jusqu’à l’analyse des 81 premiers patients inclus. Nous avons pu montrer, pour la 1ère fois, que la présence des CoPEC (Colibactin-Positive E.coli) dans la muqueuse colique des patients opérés était un facteur de risque indépendant de complications chirurgicales (OR 4.19 ; 95% IC [1.22-14.36] ; p=0.023) mais aussi particulièrement d’IPOP (OR 4.12 ; 95% IC [1.06-16.04] ; p=0.041). Une surface de graisse viscérale ≥ 180 cm2 était également significativement associée à la survenue de complications chirurgicales (OR 5.04 ; 95% IC [1.43-17.73] ; p=0.012). L’association des CoPEC et de la surface de graisse viscérale permettait de prédire la survenue de complications chirurgicales avec une aire sous la courbe ROC de 0,76. Enfin, l’analyse globale du microbiote par séquençage de l’ARNr 16S, a montré qu’un ratio Firmicutes/Bacteroidetes ≥ 1 était associé de manière indépendante à une réduction du risque de complications chirurgicales et d’IPOP (respectivement (OR 0.16 ; 95% IC [0.03-0.93] ; p=0.042) et (OR 0.13 ; 95% IC [0.02-0.81] ; p=0.029).La poursuite des travaux sur un plus grand nombre de patients devrait permettre de confirmer les signatures tissulaires bactériennes identifiées et à plus long terme d’analyser les associations de ces signatures avec les résultats oncologiques du CCR. L’analyse des prélèvements de selles pourrait permettre la mise en place d’un biomarqueur microbien non invasif (les CoPEC) prédictif de complications postopératoires. Des études précliniques pourront être développées pour obtenir une meilleure compréhension des mécanismes impliqués. Enfin, chez l’homme, des approches interventionnelles préopératoires pourront être envisagées à plus long terme en modulant la composition du MI (ciblage des CoPEC ou de la dysbiose colique) ou en améliorant la composition corporelle des patients. Ces approches pourraient être intégrées dans les programmes de réhabilitation améliorée après chirurgie (RAAC) ou de préhabilitation chez des patients sélectionnés.

    Optimal lymph node dissection for gastric cancer: a narrative review

    by Raphaël Nico, Julie Veziant, Amélie Chau, Clarisse Eveno, Guillaume Piessen

    The management of gastric cancer has long been debated, particularly the extent of lymph node (LN) dissection required during curative surgery. LN invasion stands out as the most critical prognostic factor in gastric cancer. Historically, Japanese academic societies were the pioneers in defining a classification system for regional gastric LN stations, numbering them from 1 to 16. This classification was later used to differentiate between different types of LN dissection, such as D1, D2 and D3. However, these definitions were often considered too complex to be universally adopted, resulting in wide variations in recommendations from one country to another and making it difficult to compare published studies. In addition, the optimal extent of LN dissection remains uncertain, with initially recommended dissections being extensive but associated with significant morbidity without a clear survival benefit. The aim of this review is to make a case for extending LN dissection based on the existing literature, which includes a comprehensive examination of the current definitions of lymphadenectomy and an analysis of the results of all randomised controlled trials evaluating morbidity, mortality and long-term survival associated with different types of LN dissection. Finally, we provide a summary of the various recommendations issued by organizations such as the Japanese Gastric Research Association, the National Comprehensive Cancer Network, the European Society for Medical Oncology, and the French National Thesaurus of Digestive Oncology.
