(Adenocarcinoma with other components included mucinous adenocarcinoma or signet ring cell carcinoma. Her2 negative status included IHC score 0, 1, 2 without gene amplification in FISH, while positive status included IHC score 2 with gene amplification in FISH. Distant lymph nodes included Supraclavicular lymph nodes, Posterior peritoneum lymph nodes, and other lymph nodes. One patient could have several metastatic lesions and there were some other infrequent metastatic site, such as osseous, adrenal, ovarian metastasis).
