Research Abstract

(Aim)To clarify the mechanisim of distant metastasis after radiotherapy for rectal cancer.(Methods)We used Balb/c nude mice. We cut anterior wall of rectum, and implanted HT-29 cells into posterior wall. Seven days after, we compared the several immune factors between radiation therapy group and non-therapy group using RT-PCR and flow cytometric analysis.(Result)In radiotherapy group, Foxp3, Notch1, Jagged1 mRNA ratio in tumor were not significantly increased compared with non-therapy group. Foxp3 ratio in spleen tended to be higher in radiotherapy group, compared with control and non-therapy group.(Conculusion)In radiotherapy for rectal cancer, immune tolerance by Foxp3 up-regulation in blood may increase distant metastasis. Foxp3 may be a important factor to regulate distant metastasis in rectal cancer patients with radiotherapy or chemoradiotherapy.
