Core Tip
Core Tip: Our manuscript indicated that the presence of signet ring cells (SRCs) was significantly associated with the tumor location (P = 0.022) and tumor-node-metastasis stage (P = 0.031). Meanwhile, the presence of SRCs in surgical esophageal and esophagogastric junction adenocarcinoma (EEGJA) patients predicted a poor overall survival (P = 0.002) and disease-specific survival (P < 0.001). The presence of SRC was related with advanced tumor stage and poor prognosis and could serve as a reliable and effective parameter for the prediction of postoperative survival and formulation of therapy strategy in EEGJA patients. However, more high-quality studies are still needed to verify the above findings.
