Supplementary Material for: Gastric Conduit Cancer Following Ivor-Lewis Esophagectomy for Esophageal Adenocarcinoma: A Case Report and Literature Review

The incidence of gastric cancer associated with esophageal cancer is notably high. In recent years, there has been an increase in patients with gastric conduit cancers due to early detection and radical treatment of esophageal cancer, leading to prolonged survival of the patients. Metachronous gastric cancer following esophagectomy sometimes can pose a clinical challenge for surgeons: while gastric tube reconstruction is a well-established procedure accompanying esophagectomy, treating gastric cancer within the gastric tube can be difficult in contrast. Surgical treatment of gastric tube cancers is often complex and life-threatening. Early detection of gastric tube cancer is crucial for improving prognosis, as it allows for less invasive surgical interventions. However, no specific guidelines for detecting gastric tube cancer have been established. In this report, we present a case of gastric tube cancer in a patient that had Ivor-Lewis surgery 20 years ago for preinvasive adenocarcinoma of the thoracic esophagus against the background of Barrett’s esophagus. Recommendations for earlier and more accurate diagnosis and treatment of this pathology are discussed.

与食管癌伴发的胃癌发病率显著偏高。近年来，随着食管癌早期筛查与根治性治疗的推广，患者生存期得以延长，胃代食管管道癌（gastric conduit cancer）的发病人数亦随之增加。食管切除术后出现的异时性胃癌有时会给外科医师带来临床诊疗挑战：尽管胃代食管重建术是食管切除术的经典术式，但与之相对，针对胃代食管管道内胃癌的治疗却颇具难度。胃代食管管道癌的外科治疗往往复杂且风险较高，甚至危及生命。早期检出该类癌症对改善患者预后至关重要，因其可使手术干预的创伤性大幅降低。然而，目前尚未建立针对胃代食管管道癌的特异性筛查指南。本报告中，我们将报告1例病例：患者20年前因合并巴雷特食管（Barrett’s esophagus）的胸食管浸润前腺癌接受了艾佛-刘易斯手术（Ivor-Lewis surgery），术后罹患胃代食管管道癌。本文还就该病症的更早、更精准的诊疗方案展开了讨论。
