The clinical value of mean platelet volume in predicting the therapeutic effect of TACE for HCC / 介入放射学杂志

ABSTRACT

Objective To explore the potential clinical value of mean platelet volume (MPV) in predicting the curative effect of TACE for hepatocellular carcinoma (HCC). Methods The clinical data of 263 HCC patients, who were treated with TACE at authors' hospital during the period from January 2012 to June 2016, were collected. The MPV data before initial TACE, before and after each repeated TACE were recorded. The time of tumor progression (TTP; referring to mRECIST standard), was documented. Based on the MPV determined before initial TACE, the patients were divided into low - MPV group and high - MPV group, and the TTP between the two groups was compared. Results A total of 263 patients were enrolled in this study. In HCC patients, the MPV determined before initial TACE was (9. 45±1. 24) fL, while the MPV determined after initial TACE was (9. 01±1. 11) fL, the difference between the two was statistically significant (t=4. 344, P＜0. 05). The MPV determined at the time when HCC lesion first developed progression was (9. 38±1. 16) fL, which was significantly different with the MPV of (9. 01±1. 11) fL that was obtained after initial TACE (t=3. 498, P＜0. 05). Taking the median value of MPV determined before initial TACE (9. 3 fL) as the cutoff value, the patients were divided into the low - MPV group and the high - MPV group according to patient' s MPV determined before initial TACE. Statistically significant difference in the time when HCC lesion first developed progression existed between the low - MPV group and the high - MPV group (P＜0. 05). COX regression analysis showed that BCLC stage B and C, MPV value before initial TACE were the independent risk predictors of tumor progression. Conclusion The pre-TACE and post-TACE MPV values in HCC patients treated with TACE has certain clinical significance in evaluating the curative effect of TACE. Moreover, MPV value before initial TACE has some value in predicting the time of HCC progression after TACE. (J Intervent Radiol, 2018, 27:257-262)
