Machine May Offer Novel Approach In Cancer Fight

(CBS) What if we told you that a guy with no background in science or medicine-not even a college degree-has come up with what may be one of the most promising breakthroughs in cancer research in years?

Well it's true, and if you think it sounds improbable, consider this: he did it with his wife's pie pans and hot dogs.

His name is John Kanzius, and he's a former businessman and radio technician who built a radio wave machine that has cancer researchers so enthusiastic about its potential they're pouring money and effort into testing it out.

Here's the important part: if clinical trials pan out-and there's still a long way to go-the Kanzius machine will zap cancer cells all through your body without the need for drugs or surgery and without side effects. None at all. At least that's the idea.

The last thing John Kanzius thought he'd ever do was try to cure cancer. A former radio and television executive from Pennsylvania, he came to Florida to enjoy his retirement.

"I have no business being in the cancer business. It's not something that a layman like me should be in, it should be left to doctors and research people," he told correspondent Lesley Stahl.

"But sometimes it takes an outsider," Stahl remarked.

"Sometimes it just - maybe you get lucky," Kanzius replied.

It was the worst kind of luck that gave Kanzius the idea to use radio waves to kill cancer cells: six years ago, he was diagnosed with terminal leukemia and since then has undergone 36 rounds of toxic chemotherapy. But it wasn't his own condition that motivated him, it was looking into the hollow eyes of sick children on the cancer ward at M.D. Anderson Cancer Center in Houston.

"I saw the smiles of youth and saw their spirits were broken. And you could see that they were sort of asking, 'Why can't they do something for me?'" Kanzius told Stahl.

"So they started to haunt you. The children," Stahl asked.
"Their faces. I still remember them holding on their Teddy bears and so forth," he replied. "And shortly after that I started my own chemotherapy, my third round of chemotherapy."

Kanzius told Stahl the chemotherapy made him very sick and that he couldn't sleep at night. "And I said, 'There's gotta be a better way to treat cancer.'"

It was during one of those sleepless nights that the light bulb went off. When he was young, Kanzius was one of those kids who built radios from scratch, so he knew the hidden power of radio waves. Sick from chemo, he got out of bed, went to the kitchen, and started to build a radio wave machine.

"Started looking in the cupboard and I saw pie pans and I said, 'These are perfect. I can modify these,'" he recalled.

His wife Marianne woke up that night to a lot of banging and clamoring. "I was concerned truthfully that he had lost it," she told Stahl.

"She felt sorry for me," Kanzius added.

"I did," Marianne Kanzius acknowledged. "And I had mentioned to him, 'Honey, the doctors can't-you know, find an answer to cancer. How can you think that you can?'"

That's what 60 Minutes wanted to know, so Stahl went to his garage laboratory to find out.

Here's how it works: one box sends radio waves over to the other, creating enough energy to activate gas in a fluorescent light. Kanzius put his hand in the field to demonstrate that radio waves are harmless to humans.

"So right from the beginning you're trying to show that radio waves could activate gas and not harm the human-anything else," Stahl remarked. "'Cause you're looking for some kind of a treatment with no side effects, that's what's in your head."

"No side effects," Kanzius replied.

But how could he focus the radio waves to destroy cancer cells?

"That was the next $64,000 question," Kanzius said.

The answer would cost much more than that. Kanzius spent about $200,000 just to have a more advanced version of his machine built. He knew that metal heats up when it's exposed to high-powered radio waves. So what if a tumor was injected with some kind of metal, and zapped with a focused beam of radio waves? Would the metal heat up and kill the cancer cells, but leave the area around them unharmed? He did his first test with hot dogs.

"I'm going to inject it with some copper sulfate," Kanzius explained, demonstrating the machine. "And I'm going to take the probe right at the injection site."

Kanzius placed the hot dog in his radio wave machine, and Stahl watched to see if the temperature would rise in that one area where the metal solution was and nowhere else.

"And when I saw it start to go up I said, 'Eureka, I've done it,'" Kanzius remembered. "And I said, 'God, I gotta shut this off and see whether it's still cold down below.' So I shut it off, took my probe, went down here where it wasn't injected. And the temperature dropped back down. And I said, 'God, maybe I got something here.'"

Kanzius thought he had found a way attack cancer cells without the collateral damage caused by chemotherapy and radiation. Today, his invention is in the laboratories of two major research centers - the University of Pittsburgh and M.D. Anderson, where Dr. Steven Curley, a liver cancer surgeon, is testing it.

"This technology may allow us to treat just about any kind of cancer you can imagine," Dr. Curley told Stahl. "I've gotta tell you, in 20 years of research this is the most exciting thing that I've encountered."

That's because Kanzius impressed Curley with another remarkable idea: to combine the radio waves from his device with something cutting edge - space age nanoparticles made of metal or carbon. They are so small that thousands of them can fit in a single cancer cell. Because they're metallic, Kanzius was hoping his radio waves would them heat up and kill the cancer.

"If these nanoparticles work then we truly have something huge here," Kanzius told Stahl.

Enter Rick Smalley, another cancer patient at M.D. Anderson and the man who won the Nobel Prize for discovering nanoparticles made from carbon. As luck would have it, Dr. Curley was called in one day to examine Smalley. Before leaving, he asked him for some of his nanoparticles.

"I proceeded to tell him what I wanted to do and that I thought they would heat. He looked at me with sort of a studied long look and didn't say anything. And then he looked at me and said, 'It won't work,'" Curley remembered. "And just laughed and said, 'Well, look, I'll give you some. But don't be too disappointed.'"

So Dr. Curley brought a vial of those precious nanoparticles to John Kanzius.

And on an August day in 2005, Curley and Kanzius put them to the test. Would the metallic nanoparticles heat up enough to kill cancer?

"So we take the nanoparticles, we put 'em in the radio field. And in about 15 seconds, they're boiling and heating and Steve Curley couldn't contain himself. He called Rick Smalley and he said, 'Rick, you're not going to believe this. He just blew the smithereens out of your nanoparticles,'" Kanzius recalled.

Smalley's response? "The only thing that I got out of him after this pause was, "Holy s…,'" Curley recalled.

Not long after that day, Smalley died of lymphoma. Once a skeptic, he had become one of Kanzius' biggest supporters.

"He didn't expect it, but he embraced it to his death bed when he told Dr. Curley this will change medicine forever. Don't stop, no matter what you do," Kanzius told Stahl.

And they haven't stopped. They've already shown that the Kanzius machine can heat nanoparticles and cook cancer to death in animals. Dr. Curley with rabbits, and in Pittsburgh, Dr. David Geller demonstrated to 60 Minutes how he used nanoparticles, made from gold, to kill liver cancer cells grown in rats.

"Now what we're going to do is inject the nanoparticles," Dr. Geller explained. "Directly into the tumor."

In the study the rats, anesthetized to keep them still, were exposed to the Kanzius radio waves. Dr. Geller later examined their tumors under a microscope.

"What you can see is that cells are starting to fall apart. You see white spaces in between them. The body of the cell is shrinking, the cells are starting to die," Geller pointed out.

"And can you tell from this whether the area surrounding the tumor had any destruction?" Stahl asked.

"Grossly inspecting the animal, we did not see not see any damage to the surrounding tissue," Geller said.

So far, the Kanzius method has only been applied to solid, localized tumors in animals. The ultimate goal is to treat cancer that has metastasized or spread to other parts of the body. Those undetectable rogue cells are what most often kill people with cancer and the trick is finding them.

"If we can't target the microscopic cells this is not going to be a cure," Curley said.

That's why Curley is trying to use special molecules that are programmed to target cancer cells and attach nanoparticles to them.

He showed Stahl an animation of how he hopes the targeting will work in people one day, with a simple injection of gold nanoparticles into the bloodstream.

"What we're seeing here is an example of a gold nanoparticle in this case with an antibody on it, so the antibody would be the targeting molecule," Curley explained. "You can see it is tiny compared to a normal red blood cell just imagine all of these billions of these gold nanoparticles circulating through the body and then once they get into the blood vessels going to the tumor, these nanoparticles would go through and bind on the surface of the cell."

"The cancer cell. It wouldn't bind on a normal cell," Stahl observed.

"That's right, they would bind only to the cancer cell. Now here's the nanoparticles in the cell, here comes John's radio frequency treatment. The cells get hot and they're destroyed," Curley said.

"Gosh, it does look like one of those science fiction movies," Stahl remarked.

"Right now it is a little science fiction," Curley agreed. "We're not quite to the real time yet, but it's got a lot of promise."

Even if all goes well in the lab, it'll be at least another four years before human trials can start. But John Kanzius says he's afraid he doesn't have that much time. So to help speed up the research, he's been raising millions of dollars and getting press coverage about his invention.

"Now I can't count the number of times the journalistic community, has done stories on a cancer cure," Stahl said. "I did one in 1973. …How many times have we seen these things work in the Petri dish, work with animals. And then you get them into humans and they don't work."

"Dozens," Curley replied.

But if this one does work, it most likely won't be developed in time to help the man who invented it. John Kanzius may have the option of a bone marrow transplant that could buy him more time, but after six years of chemo it would be another grueling ordeal.

"Did you ever say, 'I'm not going to do this anymore. I'm not going to put myself through it,'?" Stahl asked.

"Yes. I said that-only about a year and a half ago," Kanzius replied. "I changed my mind because I think with all the research that's going on with the institutions, that maybe, I'd like to be around for the first patient to get treated and just have a smile."

"Oh my God," Stahl said.

"And then I don't care anymore," Kanzius replied.

Cancer Therapy Without Side Effects Nearing Trials

By Jennifer Laloup Email 04.13.08 | 1:00 PM

A promising new cancer treatment that may one day replace radiation and chemotherapy is edging closer to human trials.

Kanzius RF therapy attaches microscopic nanoparticles to cancer cells and then "cooks" tumors inside the body with harmless radio waves.

Based on technology developed by Pennsylvania inventor John Kanzius, a retired radio and TV engineer, the treatment has proven 100 percent effective at killing cancer cells while leaving neighboring healthy cells unharmed. It is currently being tested at M.D. Anderson Cancer Center in Houston.

“I don’t want to give people false hope,” said Dr. Steve Curley, the professor leading the tests, “but this has the potential to treat a wide variety of cancers.”

Modern cancer treatments like radiation and chemotherapy have proven remarkably effective at treating many cancers, especially in combination, but are plagued with toxic side effects. These treatments kill healthy cells as well as cancerous ones.

Kanzius RF therapy is noninvasive, and uses nontoxic radio waves combined with gold or carbon nanoparticles, which have a long history of medical use.

Since the mid-1980s, scientists have been trying to create new medical therapies to take advantage of their tiny size. Nanoparticles made of gold, carbon and other materials can move through the bloodstream and through cell walls, allowing for efficient drug delivery, or to act like a homing devices for research purposes.

However, questions about the safety of nanoparticles are largely unanswered. Nonetheless, the potential of nanoparticles to create novel treatments has become a central thrust of many fields of medicine, including oncology.

At M.D. Anderson, Curley's research team is working on coating microscopic gold nanoparticles with cancer-seeking molecules. The proteins act as a filter that ensures nanoparticles attach only to cancerous cells in the body.

“We’re looking into gold because it is FDA-approved and has a track record of being tolerated in humans,” said Dr. Christopher Gannon, assistant professor at the Cancer Institute of New Jersey, who collaborated with M.D. Anderson.

When the gold nanoparticles are inside the malignancy, a blast from a radio-frequency generator causes them to heat and cook the cancer cells.

In trials with animal and human cells, the RF treatment destroyed 100 percent of malignant cells injected with nanoparticles, without harming surrounding healthy tissue.

A study in the November 2007 issue of the journal Cancer showed that tumor cells infused with nanoparticles and exposed to the electromagnetic field of the RF generator died within 48 hours of treatment, with no noted side effects.

A study in the Journal of Nanobiotechnology in January 2008 showed that destruction of human pancreatic cancer cells was 100 percent effective — again producing no noticeable side effects.

“We know it has the potential to work well,” said Gannon. "It’s just a matter of making the details work."

The problem is finding cancer-seeking molecules that are attracted to cancer cells but leave healthy cells alone.

Curley's team has identified a targeting molecule, c225 , which is FDA-approved. While c225 is present in many cancer cells, it also occurs in healthy cells.

“It will depend on the type of cancer and the targeting molecules attached to the nanoparticles,” Curley said.

The radio-frequency generator was invented by Kanzius, who underwent chemotherapy in 2003 and 2004 for leukemia. Kanzius declined to be interviewed for this story, citing an exclusive agreement with CBS News. 60 Minutes has scheduled a segment about Kanzius RF therapy for Sunday.

“His device helped inspire us to create the targeted nanoparticles to make it a fully functional clinical device,” said Gannon.

Kanzius is now working on a larger CT-scanner-sized device that will help scientists test larger subjects by this summer — and pave the way for human trials.

Curley, who described himself as the "ultimate skeptic," thinks the treatment is only a few years away.

"The best-case scenario is that we would be able to clinical trials within three years,” he said.

Cancer-killing waves gain national attention

Native of region to talk on '60 Minutes'
Saturday, April 12, 2008

John Kanzius is going prime time with his promising invention for cancer treatment.

Leslie Stahl will interview the Washington County native, who invented a radiofrequency (RF) generator four years ago to treat cancer, and tell his story tomorrow on CBS Television's "60 Minutes."

"It has gone from a Western Pennsylvania story to a major international story with the '60 Minutes' piece," Mr. Kanzius said from his home in Sanibel Island, Fla.

Successful inventions often end up with more uses than baking soda, and that may be the case with the Kanzius RF generator.

When he developed it years ago, his sole intent was a cancer treatment that worked without side effects.

So far, so good.

Research on his invention is on a fast track at M.D. Anderson Cancer Center in Houston and University of Pittsburgh Medical Center. The growing body of research proves his generator thermally kills cancer cells spiked with RF-reactive nanoparticles.

But last year, Mr. Kanzius discovered his RF generator also burns salt water. When Rustum Roy, a Penn State University water expert and chemist, saw it demonstrated on a YouTube video, he traveled to the laboratory that Mr. Kanzius uses in Erie to witness it firsthand.

Since then he and Mr. Kanzius have signed a cooperative agreement to study and develop the technology for commercial applications, including salt-water desalination, pollution cleanup and using RF to alter solids and metals.

Dr. Roy has shown that RF causes oxygen and hydrogen atoms to separate then reunite, creating a flame more than 3,000 degrees Fahrenheit and pure water. The RF generator is powered by electricity. The ratio of energy used vs. energy generated has yet to be determined.

"It's such an unbelievable fact -- so unbelievable that no one wants to believe it," Dr. Roy said. "It has one advantage -- an infinite and easy supply" of sea water.

Desalinating salt water while generating recoverable energy "is a tree-hugger's dream," he said. "This is a very major discovery in science."

These days Mr. Kanzius, 64, splits time between Erie and Sanibel Island, while undergoing chemotherapy for b-cell leukemia. He's raising money for the cancer research, has applied for about 50 patents and continues upgrading his inventions.

His story stands out because Mr. Kanzius is neither a doctor nor a college graduate. He holds only a technical degree from the former Allegheny Institute of Technology in Pittsburgh. Before retiring, he owned Jet Broadcasting Inc. in Erie, which operated radio and television stations. He never pondered a cancer treatment until he was diagnosed with cancer and witnessed the ill effects chemotherapy and radiation therapy had on fellow patients.

While on chemo, he spent sleepless nights doing research, which eventually made a pile from floor to ceiling. His goal became to kill cancer with physics rather than medicine. Within months he'd built a prototype for his RF generator by using his wife Marianne's pie pans then tested it by injecting metallic particles into hot dogs and steaks. The RF cooked only the injected areas.

His ideas drew early interest from Dr. David A. Geller, co-director of the UPMC Liver Cancer Center, then Dr. Steven Curley, a liver cancer specialist at M.D. Anderson -- the No. 1 cancer research center in the world. They now are conducting research using Mr. Kanzius' equipment and general protocol.

The current hope is to use the Kanzius treatment on a wide range of cancers with added interest in applying the procedure to fungal, viral and bacterial infections.

For now, the goal is developing a means to tag RF-sensitive nanoparticles with antigens or proteins so they infiltrate only cancer cells. Once nanoparticles are inside cancer cells, RF can heat them to deadly temperatures in seconds or minutes without affecting healthy tissue.

Last May, Dr. Curley described the Kanzius project as "the most exciting new therapy for cancer" he's seen in his 20 years of research.

In February, Dr. Geller at UPMC presented a paper to a large group of surgeons at the Academic Surgical Congress in Los Angeles that showed that tumors under the skin can be destroyed with RF when injected with gold nanoparticles developed at Pitt. The research will be published in August in the journal Surgery.

"In looking back after three years of working on the radiowave research, I have more enthusiasm than ever, in part because the machine does generate heat, and gold nanoparticles are excellent enhancers to focus the RF," Dr. Geller said.

The ideal, he said, is to create nanoparticles that serve "as homing pigeons" to cancer.

"There's no question that momentum is growing and the ongoing press coverage, as well as '60 Minutes' coverage, makes me want to be enthusiastic without providing false hope," he said, suggesting that patients seek other forms of treatment in the meantime. "The goal is to move the cancer research forward as quickly as possible to find tomorrow's cure."

Mr. Kanzius describes his experience to date as "an amazing odyssey."

"The sooner it gets into human trials, the happier I'll be," he said.
