It is still unclear whether cell-free DNA (cfDNA) can replace solid-tissue biopsy. A 59-year-old man developed castration-resistant prostate cancer with a liver metastasis. We performed a liver biopsy and collected a cfDNA sample. Although he underwent radiofrequency ablation, tumors recurred and he was transferred to another hospital. We performed next-generation sequencing using DNA from the biopsy tissue and cfDNA. BRCA2 p.T3033fs and AURKA F31I were detected in both the biopsy tissue and the cfDNA. cfDNA may be useful as a liquid biopsy for monitoring the gene profile of aggressive prostate cancer.

游离DNA(cfDNA)是否能够替代实体组织活检尚不清楚。一名59岁男性患去势抵抗性前列腺癌并伴有肝转移。我们进行了肝脏活检并采集了一份cfDNA样本。尽管他接受了射频消融治疗,但肿瘤复发,随后他被转至另一家医院。我们使用活检组织和cfDNA中的DNA进行了二代测序。在活检组织和cfDNA中均检测到BRCA2 p.T3033fs和AURKA F31I。cfDNA作为一种液体活检手段,可能有助于监测侵袭性前列腺癌的基因图谱。
