CRP and endometrioid stromal sarcoma: The levels of erythrocyte sedimentation rate (median 66.5 vs 35 mm/h, P < 0.001) and CRP (median 38.99 vs 11.26 mg/L, P < 0.001) were significantly higher, whereas the lymphocyte count (0.91 vs 1.27 ×109/L, P <0.001) was obviously lower in ESS patients than those of non-ESS patients.
