This idea has been around for some time. But it is finally working. And it might soon be applied to cancers other than prostate cancer.
Destroying Prostate Cancer Tumors with Gold NanoparticlesWhen Frank Billingsley announced he had prostate cancer, the outpouring of sympathy was overwhelming. But one email among the mass of messages the chief meteorologist at KPRC-TV in Houston received stood out.
"I got this email from David Jorden's wife, Melanie," Billingsley said. "David Jorden is the CEO of Nanospectra," a Houston-based company conducting a clinical trial of a nanoparticle-based cancer treatment developed at Rice University.
Billingsley had never heard of the treatment developed in the same city where he's been a popular television personality for almost three decades. His reaction: "Wow, this is really out there, but I would like to at least know about it."
Maybe it seemed "out there" to Billingsley, but it's long been a quest of Rice University engineer and nanoscientist Naomi Halas — to develop a treatment that destroys tumors without the debilitating side effects of chemotherapy, invasive surgery and radiation.
In November 2018, Billingsley received a nanoparticle infusion and underwent a laser ablation procedure the next day as part of a clinical trial at the University of Texas Health Science Center in Houston. An MRI the next week showed no signs of cancer.
"The nanoparticles are special in that you can design a nanoparticle to absorb light at wavelengths that pass directly through the body," Halas said. "So if the particles are placed in a tumor site, you can irradiate them with light that penetrates through the body. And the nanoparticles will absorb the light, convert the light to heat and very gently they will induce hyperthermia and destroy just the tumor cells."
