Which supraclavicular node is associated with gastric adenocarcinoma?

The supraclavicular node associated with gastric adenocarcinoma is known as Virchow's node. This node is located in the left supraclavicular fossa and is often considered a sentinel node for cancers of the abdomen, including gastric cancers. The involvement of Virchow's node in gastric adenocarcinoma can occur when the cancer metastasizes, indicating a more advanced disease stage.

The clinical significance of Virchow's node lies in its association with abdominal malignancies; when it is enlarged, it often warrants further investigation for potential underlying cancers, including those of the stomach. Early detection of such metastasis can be crucial for patient management and treatment planning.

In contrast, the other choices relate to different anatomical structures or clinical significance. The sentinel node refers to the first lymph node that drains a specific area and is often assessed for the presence of cancer spread but is not specific to gastric adenocarcinoma. The Sister Mary Joseph nodule is a periumbilical mass associated with intra-abdominal malignancies, including ovarian and gastrointestinal cancers but not exclusive to the supraclavicular area. Level II nodes relate to regional lymph node classification but do not specifically indicate association with gastric adenocarcinoma. Understanding these distinctions
