now this could be fun (by laurie)


I’ve written before about the one major limitation of Herceptin – that it doesn’t cross the brain-blood barrier. A couple of years ago (after meeting several young women with metastasis that had spread to the brain), I underwent a brain MRI. To my very great relief, there was no evidence of trouble but I think I’ll will be requesting another before too long.

A few days ago, my friend Deanna posted a link to Breast Cancer? But Doctor…I Hate Pink and to Ann’s take on the news that Viagra may help Herceptin to (ahem) penetrate the blood-brain barrier and thus help reduce the size of brain tumours.

As Anne tells it:

“Herceptin, the wonder drug, has a flaw: it does not cross the blood-brain barrier. The blood-brain barrier was erected designed by nature to protect our brains from dangerous substances, such as bad viagra jokes, but what it means for cancer patients is that certain drugs can’t get through to kill swollen bad cells. Herceptin cannot treat HER2+ breast cancer that has engorged spread invaded the brain. Apparently, if you add a big large generous dose of Viagra to Herceptin, it adds enough thrust power to break through that blood-brain barrier and bathe the brain in its heaving healing properties.”

It’s seriously interesting news but go read Ann’s full post. It will make you laugh.
