- however, some tumor cells pass through the vascular wall and develop parenchymal metastasis in the alveolar space or the interstitium. (medscape.com)
- thus, tumors with a high cell turnover are most susceptible (certain leukemias and lymphomas, small proliferating tumors, "recruited" tumor cells, and micrometastases). (doctorlib.info)
- The tumor initially spreads via a hematogenous route to the pulmonary arterioles and capillaries with retrograde spread from hilar nodal metastases or upper abdominal tumors, but subsequently extends through the vascular walls, invades the low resistant peribronchovascular lymphatics, and spreads along the lymphatics. (medscape.com)
- It is also employed for the detection of malignant tumors including those of the brain, liver, and thyroid gland. (lookformedical.com)
- Lymphatic spread occurs either in an antegrade fashion by lymphatic invasion through the diaphragm and/or pleural surfaces or retrograde lymphatic spread from hilar lymph nodal metastasis. (medscape.com)

- We evaluated the relationships between clinicopathologic factors and the occurrence of late cervical lymph node metastasis. (biomedcentral.com)
- The clinicopathological factors associated with late cervical lymph node metastasis were the mode of invasion (MOI, p = 0.032), depth of invasion (DOI, p = 0.004), and perineural invasion (PNI, p = 0.040). (biomedcentral.com)
