Outline of Final Research Achievements |
The outcome of patients with malignant tumors is poor if they suffer from lung metastases. Myeloid-derived suppressor cells (MDSCs), a major player for tumor-induced immunosuppression, can be suppressed by certain chemotherapeutic agents, such as low-dose 5- fluorouracil (5-FU) or surgical treatment. Early-phase treatment by low-dose 5-FU chemotherapy and resection of primary tumors improved survival, which was concomitant with a reduction of lung-accumulating MDSCs and lung metastases. Early-phase treatment may provide therapeutic values to prevent MDSC-mediated lung metastasis formation in tumor-bearing hosts. Secondly, the frequency of MDSCs in the peripheral blood of tumor-bearing mice reflects the status of tumor progression as well as tumor recurrence. Continuous monitoring of MDSCs in the peripheral blood might be a useful indicator of tumor recurrence.
