Investigators have used administrative claims to better understand cancer outcomes when a research question cannot feasibly be examined within a study. The Prostate Cancer Prevention Trial (PCPT) showed that seven years of finasteride reduced prostate cancer (PC) risk by 25% in men age 55 years or older. However, it was unclear whether the observed reduction in PC for finasteride participants would be maintained after finasteride discontinuation.

使用Medicare索赔在前列腺癌预防试验中检查Finasteride的长期前列腺癌风险

当无法在一项研究中切实地研究一个研究问题时，研究人员已使用行政要求更好地了解癌症的结局。前列腺癌预防试验（PCPT）显示，非那雄胺7年可使55岁以上男性的前列腺癌（PC）风险降低25％。但是，目前尚不清楚停用非那雄胺后是否能维持观察到的非那雄胺参与者的PC降低。
