It is worth to remember that there is a way to completely cure HIV, but it is very dangerous, requires a very specific bone marrow match, and does not erradicate all subtypes of the virus. Still, it is interesting:
Rather than thinking of this as a way to cure HIV, I think of it as a demonstration that if someone has a life-threatening blood cancer – something so acutely lethal that you will take the risk of destroying their entire bone marrow – then if you can find matched but CCR5-deficient donors, you can also potentially cure their HIV.
Yes, but the underlying mechanism - the deletion in the CCR5 receptor coding fragment - is a known source of HIV immunity in humans.
The bigger problem here is that bone marrow transplant is by itself more dangerous than an antiretroviral-controlled HIV infection. Not to mention that CCR5 deletions are quite rare.

To be sure that this new treatment is useful you must try it in a double blind experiment with many patients for many years.
Now, it's only an interesting idea with some in vitro support, but it's no a real cure. The title "HIV flushed out by cancer drug" is an optimistic exaggeration.
This is not the problem since you can chase out any remaining virus just by extending the treatment time. The real problem is viral reservoirs that the treatment does not reach (eg behind the blood brain barrier).
Having said this if I was infected with HIV this is exactly what I would be doing (ie treating with drugs that suppressed viral replication while chasing the latent virus out of hiding).
The lymphatic system is a return (drainage) system. What is more interesting is that it has been recently found that ultrasounds can make the blood brain barrier leaky allowing you to get drugs into the brain that normally are blocked.
It would be interesting if a similar approach might be applied to flush out latent Chickenpox virus (VZV) from people whom experienced active disease because of the massive risk of Shingles' long-lasting, debilitating symptoms later in life.
