IVF May Be Linked to Rare Eye Tumor
Dutch Study Shows Cluster of Retinoblastoma Cases
In a news release issued Friday, an association representing more than 4,000 European fertility specialists urged caution in interpreting the Dutch study. The European Society of Human Reproduction and Embryology release also cited the larger studies showing no increased occurrence of cancer among almost 20,000 IVF children.
Society chairman Hans Evers says the Dutch study could easily have overestimated the risk because it was so small.
"Of course, this does not exclude a connection between assisted reproduction techniques and childhood cancer, and everyone involved in fertility treatment agrees that it is extremely important to follow these children right through their childhood," Hans Evers says in the news release. "But the present report should be treated cautiously for now."
BenEzra agrees that this study may have overestimated the risks of retinoblastoma in this population.
