Three ovarian neoplasms (choriocarcinoma, yolk sac carcinoma, and teratoma) were diagnosed in a 2 yr carcinogenicity study involving B6C3F1 mice. The yolk sac carcinoma and the teratoma occurred in opposite ovaries of a single female mouse that was sacrificed in extremis on study day 725. The choriocarcinoma occurred in a female mouse that was sacrificed in extremis on study day 565. These neoplasms were considered to be spontaneous in origin.
在一项为期2年的B6C3F1小鼠致癌性研究中,诊断出3例卵巢肿瘤(绒毛膜癌、卵黄囊癌和畸胎瘤)。卵黄囊癌和畸胎瘤发生在一只雌性小鼠的双侧卵巢,该小鼠在研究第725天时濒死处死。绒毛膜癌发生在一只雌性小鼠,该小鼠在研究第565天时濒死处死。这些肿瘤被认为是自发产生的。
