胃癌腹膜转移的影像诊断和研究进展

Imaging diagnosis and research progress of gastric cancer in peritoneal metastasis

目前,胃癌是我国最常见和最致命的肿瘤之一,腹膜转移是进展期胃癌患者常见转移或复发方式,预后极差。近年来影像技术不断进步,CT、US、MRI、PET-CT等影像学检查均用于评估腹膜转移,但对腹膜转移的准确检测,特别是对隐匿性腹膜转移的诊断仍具有挑战性。随着精准医学概念的提出,影像组学和人工智能技术进入了高速发展阶段,并在早期预测胃癌腹膜转移方面具有较大潜能,为胃癌腹膜转移患者的诊治提供了新的手段。

Gastric cancer remains one of the most prevalent and fatal malignancies in China.Peritoneal metastasis represents a frequent mode of dissemination or recurrence in patients with advanced disease and confers an extremely poor prognosis.In recent years,considerable progress has been made in imaging techniques,with modalities including CT,ultrasound,MRI and PET-CT being implemented to evaluate peritoneal metastasis.However,adequate detection remains challenging,particularly for occult peritoneal metastasis.With the advent of precision medicine,radiomics and artificial intelligence have undergone rapid development and show considerable promise for the early prediction of peritoneal metastasis in gastric cancer,providing a new means of diagnosis and treatment for patients with peritoneal metastasis.
