SPARCL1 and neoplasm: Factors associated with PFS by Kaplan-Meier univariate analysis were radical degree (P < 0.001), distant metastasis at the time of initial diagnosis (P < 0.05), tumor size (P < 0.001), mitotic count (P < 0.001), NIH risk classification (P < 0.001), and SPARCL1 expression (P < 0.001).
