This hypothesis would imply that lymphoma cells, on repeated metastatic cycles, would acquire such a highly aggressive phenotype that they no longer require contact with ICAM-1 at later stages of metastasis.

We found that on repeated in vivo passages, a selective pressure favored the lymphoma cells that constitutively express high levels of matrix metalloproteainse-9 (MMP-9), a gene associated with a poor clinical outcome in non-Hodgkins's lymphoma.
We further found that although the parent lymphoma cells could not grow tumors in ICAM-1–deficient mice, the aggressive lymphoma variants could.It also binds several non-integrin ligands including CD43/Sialophorin, Fibrinogen, Hyaluronan, rhinoviruses, and Plasmodium falciparum-infected erythrocytes.Soluble ICAM-1 promotes angiogenesis and serves an indicator of vascular endothelial cell activation or damage.In the initial stage, down-regulation of cell membrane integrins that interact with extracellular matrix proteins favors the spread of tumor cells by allowing them to detach from the primary tumor and enter the circulation.1 In later stages of metastasis, however, expression of adhesion molecules favoring intercellular contacts is necessary for the efficient spreading of metastatic cells.2-5 Although the latter was first thought to provide specific homing signals for the invasion of target organs, the observation that metastatic and nonmetastatic cells home to target organs with the same efficiency and kinetics supports the view that adhesion molecules rather control processes after homing.6-8 The most compelling evidence supporting this view is that mice deficient in intercellular adhesion molecule (ICAM-1) are resistant to dissemination of lymphoma cells to peripheral organs, yet lymphoma cells migrate with the same efficiency to target organs in both normal and ICAM-1–deficient mice.5 Although the resistance mechanism of ICAM-1–deficient mice to lymphoma metastasis is still unclear, 2 possible scenarios deserve particular attention.First, it is conceivable that resistance simply consists in the absence of ICAM-1 induced “tumor welcoming signals” in stromal cells.When Channel 3 Eyewitness News is not airing a live newscast, you will see replays of the most recent newscast.
