Purpose The purpose of this study was to investigate the relationship between platelet indices [mean platelet volume (MPV), platelet count (PLT), platelet distribution width (PDW) and plateletcrit (PCT)] at diagnosis in osteosarcoma. Methods The information of 233 patients with osteosarcoma at diagnosis between 2007 and 2015 was retrospectively reviewed. Clinical parameters such as gender, age, size and site of tumor, and tumor necrosis rate after neoadjuvant chemotherapy were analyzed. Results No significant difference was noted in the mean values of MPV, PLT, PDW and PCT among stage I, II and III patients. In localized patients, the median disease-free survival (DFS) values were 42 and 22 months in the PLT<300×10 9 /L and ≥300×10 9 /L groups, respectively, but the difference was not statistically significant ( P = 0.2611). No difference in the DFS among the three different levels of MPV was observed. Conclusion No significantly different platelet indices were noted among the different stages. Although a shorter median DFS was found in localized patients with PLT≥300×10 9 /L, there was still a lack of strong evidence to demonstrate the association between platelet indices and osteosarcoma.
