Abstract

In the present study, we aimed to characterize the predictive value of cytokines/chemokines in rectal cancer (RC) patients receiving chemoradiation therapy (CRT). Blood samples were obtained pre- and post-CRT from 35 patients with advanced RC, who received neoadjuvant CRT followed by surgery, and the correlation between plasma levels of cytokines/chemokines and the response to CRT was analyzed. The pre-CRT levels of soluble CD40-ligand (sCD40L) and the post-CRT levels of chemokine ligand-5 (CCL-5) were significantly associated with the depth of tumor invasion and with venous invasion. In addition, a significant decrease in sCD40L and CCL-5, as well as in platelet counts, was associated with a favorable response to CRT. A significant correlation between pre-CRT platelet counts and sCD40L was observed in patients with a favorable response. By contrast, higher post-CRT interleukin (IL)-6 was associated with a poor response. Platelets, immune system and cancer cells, cross-linked through various cytokines/chemokines, appear to play an important role in the response to CRT, and by understanding their roles, new approaches for the improvement of the therapy might be proposed.
