Chimeric Antigen Receptor-T Cell Therapy Decreases Distant Metastasis and Inhibits Local Recurrence Post-surgery in Mice.
Distant metastasis and primary tumor relapse are the two main hurdles to the success of surgical treatment for cancer patients. Circulating tumor cells (CTCs) and incomplete surgical resection are the primary cause of distant metastasis and local recurrence of tumors, respectively. Chimeric antigen receptor (CAR)-modified T cells target residual carcinomas and CTCs hold the potential to inhibit primary recurrence and reduce tumor metastasis, but the experimental evidence is lacking. Here, we developed a surgery-induced tumor metastasis model in immunocompetent mice to investigate the efficacy of CAR-T cells therapy in preventing metastasis and local recurrence. We observed that subcutaneous tumor resection has induced a large number of CTCs intravasated into circulation. EpCAM-specific CAR-T was effective in clearing CTCs following surgical removal of the tumor. This resulted in less pulmonary metastasis and longer survival in mice when compared to mice treated with surgery followed by Mock-T cells infusion. In addition, the local relapse was obviously inhibited at the surgical site followed by EpCAM-CAR-T cell treatment. This study demonstrated that CAR-T cell therapy can be an adjuvant treatment following surgery to prevent tumor metastasis and inhibit primary tumor relapse for cancer patients.
