Abstract: BACKGROUND: Ovarian cancer (OC) is one of the most malignant gynecological cancers. Platelets play a profound role in cancer growth and metastasis. Platelet distribution width (PDW) is an indicator of platelet activation and is altered in malignancies. However, the prognostic value of PDW in OC remains unclear. This present study aimed to investigate the predictive significance of PDW in OC. METHODS: 221 OC patients, between January 2013 and December 2013, were included in this study. The correlations between PDW and clinicopathological features were analyzed. Kaplan-Meier method and Cox regression were used to evaluate the prognostic impact of PDW. RESULTS: Of the 221 patients, increased PDW levels were observed in 163 (73.6%) patients. Kaplan-Meier analysis revealed that higher PDW levels were associated with poor progression-free survival and overall survival (both p< 0.001). Cox-regression analysis confirmed the independent predictive value of PDW on overall survival (HR = 2.820, 95% CI = 1.776–4.476, p< 0.001). CONCLUSION: Higher PDW levels predict poor prognosis in patients with OC. Elevated PDW may be a novel target for therapy.
