The treatment of advanced gastric carcinoma by various neoadjuvant and adjuvant multimodal therapy regimes is under current investigation to improve the poor outcome of these patients. Therefore, pretherapeutic tumor staging according to the TNM classification is essential for the optimal application of various therapeutic modalities. According to recent studies, endoscopic ultrasonography (EUS) is the most sensitive technique in measuring tumor infiltration (T-staging). In addition, although less reliable compared to the T-staging, the sensitivity of EUS in assessing lymph node status (N-staging) is superior to computed tomography and conventional ultrasound. Pretherapeutic laparoscopic investigation may give additional important information about tumor stage. This overview describes the significance of various diagnostic techniques that can be applied in tumor staging investigations.
目前正在研究采用各种新辅助和辅助多模式治疗方案来治疗晚期胃癌，以改善这些患者的不良预后。因此，根据TNM分类进行治疗前肿瘤分期对于各种治疗方式的最佳应用至关重要。根据最近的研究，内镜超声检查（EUS）是测量肿瘤浸润（T分期）最敏感的技术。此外，尽管与T分期相比可靠性稍低，但EUS评估淋巴结状态（N分期）的敏感性优于计算机断层扫描和传统超声。治疗前的腹腔镜检查可能会提供有关肿瘤分期的其他重要信息。本综述描述了可应用于肿瘤分期检查的各种诊断技术的意义。
