猴空泡病毒40及类猴空泡病毒40作为潜在风险因素。

Arch Geschwulstforsch. 1983;53(3):217-26.

SV 40 and its derivatives are highly suspicious of being risk factors involved in the development of certain intracranial tumors. Therefore further activities should be undertaken to prove or to disregard this suspicion especially with respect to the world-wide man-made dissemination of SV 40 among the human population.

猴空泡病毒40（SV 40）及其衍生物极有可能是某些颅内肿瘤发生发展的风险因素。因此，应开展进一步的研究活动，以证实或排除这一怀疑，特别是考虑到SV 40在全球范围内通过人为因素在人群中的传播情况。
