Prognostic Impact of Thoracic Extra-regional Lymph Node Metastasis Defined By the 12th Japanese Classification Following Definitive Radiotherapy for Esophageal Squamous Cell Carcinoma.
Purpose: The aim of this study was to investigate the prognostic impact of thoracic extra-regional lymph node metastasis (M1b-LYM, determined by the 12th edition of the Japanese Classification of Esophageal Cancer) in definitive radiotherapy for esophageal squamous cell carcinoma.
Methods: Eighty-six consecutive patients who underwent definitive radiotherapy for esophageal squamous cell carcinoma between 2017 and 2022 at our institute were included in this retrospective study. Progression-free survival (PFS), overall survival (OS), distant metastasis (DM), and loco-regional recurrence (LR) were compared between patients with and without M1b-LYM using Kaplan-Meier or cumulative incidence function analysis.
Results: Among the 86 patients, 15 had M1b-LYM metastasis (the M1b( +) group) and 71 had no M1b-LYM metastasis (the M1b(-) group). The median follow-up period was 38 months. The 2-year PFS, OS, cumulative incidence of DM, and cumulative incidence of LR for the M1b(-) group versus M1b( +) group were 41% vs 20% (p = 0.129), 58% vs 47% (p = 0.172), 31% vs 33% (p = 0.906), and 31% vs 60% (p = 0.0369), respectively. Multivariate analysis showed that M1b( +) was associated with higher LR (p = 0.0350), T stage was associated with poorer PFS (p = 0.0138), and omitting chemotherapy was associated with poorer PFS (p = 0.0160) and OS (p < 0.01).
Conclusion: The presence of thoracic extra-regional lymph node metastasis was associated with poor loco-regional control but not distant metastasis or survival in esophageal squamous cell carcinoma patients after definitive radiotherapy.
Trial registration number: This study was retrospectively registered on 21 June 2024 (R06-053).
期刊介绍：
The Journal of Gastrointestinal Cancer is a multidisciplinary medium for the publication of novel research pertaining to cancers arising from the gastrointestinal tract.The journal is dedicated to the most rapid publication possible.The journal publishes papers in all relevant fields, emphasizing those studies that are helpful in understanding and treating cancers affecting the esophagus, stomach, liver, gallbladder and biliary tree, pancreas, small bowel, large bowel, rectum, and anus. In addition, the Journal of Gastrointestinal Cancer publishes basic and translational scientific information from studies providing insight into the etiology and progression of cancers affecting these organs. New insights are provided from diverse areas of research such as studies exploring pre-neoplastic states, risk factors, epidemiology, genetics, preclinical therapeutics, surgery, radiation therapy, novel medical therapeutics, clinical trials, and outcome studies.In addition to reports of original clinical and experimental studies, the journal also publishes: case reports, state-of-the-art reviews on topics of immediate interest or importance; invited articles analyzing particular areas of pancreatic research and knowledge; perspectives in which critical evaluation and conflicting opinions about current topics may be expressed; meeting highlights that summarize important points presented at recent meetings; abstracts of symposia and conferences; book reviews; hypotheses; Letters to the Editors; and other items of special interest, including:Complex Cases in GI Oncology: This is a new initiative to provide a forum to review and discuss the history and management of complex and involved gastrointestinal oncology cases. The format will be similar to a teaching case conference where a case vignette is presented and is followed by a series of questions and discussion points. A brief reference list supporting the points made in discussion would be expected.
