Abstract
BACKGROUND: Renal cell carcinoma (RCC) is the third most common genitourinary cancer. Activated platelets play a pivotal role in cancer development and progression. Altered mean platelet volume (MPV) has been reported in several malignancies. The aim of the present study was to investigate the association of MPV with RCC. STUDY DESIGN: The study consisted of 145 patients with RCC, 110 patients with benign renal tumor and 132 healthy control subjects between January 2015 and December 2015. All participants' clinical and laboratory characteristics at initial diagnosis were collected. The odds ratios (ORs) for RCC were calculated using multivariate logistic regression analysis after adjusting for confounding variables across MPV quartiles. RESULTS: The patients with RCC had decreased pre-operative MPV compared to the patients with benign renal tumor and healthy control subjects. Furthermore, pre-operative MPV was reduced in benign renal tumor compared with healthy control subjects. Surgical tumor resection resulted in a significant increase in MPV levels (8.7 fL vs. 9.0 fL; p = 0.011). After adjusting for other risk factors, the ORs (95% CIs) for RCC in each MPV quartile were 25.725 (7.556-87.585), 7.447 (2.701-20.537), 0.703 (0.245-2.019), and 1.000, respectively. CONCLUSIONS: RCC patients have remarkably reduced MPV compared to patients with benign renal tumor and healthy control subjects. Moreover, decreased MPV was independently associated with RCC. Our results suggest that detection of MPV may be useful to assess the risk of RCC.
