Study Notes
Lymphatic Spread of Malignant Cells
- Coeliac lymph nodes can be a site for malignant cells to metastasize.
- Cells can travel to the cisterna chyli, then to the thoracic duct.
- Left supraclavicular lymph nodes, also known as Virchow's glands, can be affected through retrograde lymphatic permeation.
Implications for Stomach & Small Intestine Cancer
- Malignant cells may spread retrogradely from coeliac lymph nodes to lymphatics around the hepatic artery.
- This retrograde spread can cause enlargement of lymph nodes in the porta hepatis.
- From the porta hepatis, malignant cells may metastasize to the liver or, through lymphatics in the falciform ligament, travel around the ligamentum teres.
- This metastasis can result in the development of a malignant nodule at the umbilicus, referred to as Sister Joseph's nodule.
