Chemokines, proteins chemotactic for leukocytes and non-leukocytes, have been intensively studied for their role in tumor growth and metastasis. Recent work has shown that particular chemokines may have multiple effects on tumors including promoting growth, angiogenesis, metastasis, and suppression of the immune response to cancer, while other chemokines inhibit tumor mediated angiogenesis and promote anti-tumor immune responses. Increasing biological evidence supports the hypothesis that tumor-generated chemokines provide more than simply angiogenic signals. Tumor-derived chemokines may potentially act as inhibitors of anti-tumor immune responses as well as autocrine growth factors for the tumor. The complexity and redundancy of tumor chemokine expression suggests that a single chemokine target for tumor therapy may not be appropriate. Indeed, multiple target therapy including blockade of tumor enhancing chemokines while delivering or inducing the secretion of anti-tumor chemokines is the approach that currently holds the most promise. The role of chemokines in tumor biology as well as various means of blocking chemokines in cancer models in order to develop successful therapeutic strategies will be discussed.
