| Outline of Final Research Achievements |
We investigated myeloid-derived suppressor cells (MDSCs) in the peripheral blood of patients with advanced urothelial cancer (UC) who received systemic chemotherapy. The number of MDSCs in UC patients was larger than that in healthy volunteers. There was no relationship between the number of MDSCs at baseline and the response to chemotherapy. The number of MDSCs declined during chemotherapy in only 25% of the patients. There was no relationship between the decline of MDSCs and the response to chemotherapy. In conclusion, the standard regimens cannot decrease the number of MDSCs in UC patients, which does not support the synergic effect of immunotherapy and chemotherapy.
