Objectives:
It remains unclear whether the immunologic status of cells in peripheral blood can be used as a prognostic indicator of response to treatment for patients with neoadjuvant chemotherapy (NAC). This study sought to evaluate whether the proportion of granulocytic myeloid-derived suppressor cells (G-MDSCs) and monocytic myeloid-derived suppressor cells could correlate with pathologic response in bladder cancer patients receiving NAC.
Patients And Methods:
Pretreatment peripheral blood levels of G-MDSCs and monocytic myeloid-derived suppressor cells were measured by flow cytometry. We divided patients into high and low (above and below the median, respectively) groups based on the median value for each immune cell subset and compared outcomes of the two groups.
Results:
A significant pathological response (pT0-1) was attained in 13% (6 of 45) of patients with high G-MDSCs compared with 58% (26 of 45) of patients with low G-MDSCs (P < 0.001). Patients with high G-MDSCs had significantly shorter disease specific survival and progression-free survival (both P < 0.001). In the multivariate analysis for survival, high G-MDSCs and pathological response emerged as independent prognostic factor for progression-free survival (P < 0.001 and P = 0.017) and disease-specific survival (P < 0.001 and P = 0.014).
Conclusions:
Pretreatment peripheral G-MDSCs may represent a potential marker for the outcome of patients treated with cisplatin-based NAC.
