A Philadelphia judge granted summary judgment in the case of a woman who said her breast cancer was caused by her ingestion of hormone-replacement therapy drugs because the plaintiff did not have any evidence to show that the one prescriber she identified had done more than refill her prescription.

In a second HRT decision, another Philadelphia judge said that two defense verdicts in dual HRT cases tried together in 2010 should be upheld because Wyeth, now owned by Pfizer, presented several experts to show that the women’s breast cancer could have been caused by factors other than HRT.
