By studying the HLA system, evidence of immunization by paternal antigens inherited by the antecedent child has been obtained in primiparous patients who subsequently developed choriocarcinoma. The same approach has been used to show which pregnancy was likely to be casual in two patients with complicated obstetric histories.
通过研究人类白细胞抗原（HLA）系统，在随后发生绒毛膜癌的初产妇中，已获得由前一个孩子遗传的父源抗原免疫的证据。同样的方法已被用于确定两名有复杂产科病史的患者中哪一次妊娠可能是偶然发生的。
