Prognostic value of fibrinogen change value in adrenocortical carcinoma patients

The aim was to explore the preoperative and postoperative fibrinogen changes value (FCV) as a prognosis biomarker for in patients with adrenocortical carcinoma (ACC).

We identified 42 patients with ACC and 190 patients with adrenal adenoma (AA) who underwent surgery at our institution between 2015 and 2023. Preoperative fibrinogen, postoperative fibrinogen and follow-up information of the patients were recorded and analysed. The relationship between FCV and overall survival (OS)/ relapse-free survival (RFS) was evaluated.

The mean level of preoperative and postoperative fibrinogen for ACC were 4.00 ± 1.64 g/L and 2.75 ± 0.59 g/L, respectively (p < 0.001). The mean level of preoperative and postoperative fibrinogen for AA were 2.79 ± 0.59 g/L and 2.71 ± 0.58 g/L, respectively (p = 0.144). In ACC, the lower FCV (≤ 1.25 g/L) showed a significantly poorer RFS than the higher (> 1.25 g/L) (p = 0.007); however, the lower FCV (≤ 1.25 g/L) showed no poorer OS than the higher (> 1.25 g/L) (p = 0.243). On multivariate survival analyses, FCV remained a predictor of RFS (HR 3.138).

According to the data in this study, it can be said that FCV is correlated with prognosis of ACC. The FCV might be a new biomarker for predicting the RFS of ACC.
