讨论 胃癌的转移以直接浸润和淋巴转移为主,通常是在腹腔内转移。体表转移灶一般是通过胸导管转移到左锁骨上淋巴结和通过肝圆韧带淋巴管转移至脐周。而胸部的皮肤和皮下转移少见。其确切的转移途径尚不肯定,一是可能通过血行转移;二是经过特殊的淋巴转移途径。本组3例体表转移灶都局限在胸壁,且肝、肺等脏器均未见转移灶, Discussion Gastric cancer metastasis is dominated by direct infiltration and lymphatic metastasis, usually in the abdominal cavity. Surface metastases are generally transferred to the left supraclavicular lymph node through the thoracic duct and to the umbilical periphery through the round ligamentous lymph vessels of the liver. The chest skin and subcutaneous transfer are rare. The exact route of metastasis is not yet certain, one may be through blood transfer; the second is through a special lymph node metastasis. 3 cases of surface metastases in this group were confined to the chest wall, and no metastases were found in the liver, lungs, and other organs.
