Diagnostic Value of sCD163 Combined with PCT and HS-CRP in Patients with Gynecological Malignant Tumors and Fever.

Objective: To explore diagnostic values of sCD163 with PCT and HS-CRP in diagnosing infection among patients with gynecological malignant tumors and fever.

Methods: Cross-sectional, observational study. Methods: Huzhou Maternity & Child Health Care Hospital, China, from May 2018 to February 2020. Methods: A total of 119 patients with gynecological malignant tumors and fever were divided into infected group (70 cases) and non-infected group (49 cases), according to the blood bacterial culture results and clinical symptoms. Serum PCT, HS-CRP, sCD163 level were compared. Pearson correlation was performed to analyse correlation of sCD163 with PCT and HS-CRP. The area under the curve (AUC) score was calculated from receiver operating characteristic curve (ROC).

Results: Serum sCD163, PCT and HS-CRP levels in infected group were all elevated compared to non-infected group (all p <0.001). Pearson correlation analysis showed that sCD163 was positively correlated with PCT and HS-CRP (r = 0.596, p <0.001; r = 0.744, p <0.001, respectively). The AUC of sCD163 + PCT + HS-CRP combined detection for predicting early infection in patients with gynecological malignant tumors and fever was 0.905 (95% CI: 0.855-0.956), which was greater than sCD163, PCT, and HS-CRP detected alone.

Conclusions: Combined detection of sCD163 with PCT and HS-CRP has a high diagnostic efficiency for early infection in patients with gynecological malignant tumors and fever, which is better than that of sCD163, PCT or HS-CRP alone. It can be used as an effective auxiliary examination method and an indicator for differential diagnosis. Key Words: sCD163, PCT, HS-CRP; Gynecology, Tumor, Infection, Diagnosis.
