Study finds cancer ‘vaccine’ eliminated tumors in mice

STANFORD, Calif. — Researchers at Stanford University School of Medicine say a cancer treatment experiment was shown to eliminate all traces of cancer in 87 of 90 mice.

The study says this approach could work for many types of cancer and provide a rapid and relatively inexpensive cancer therapy.

It’s also unlikely to cause adverse side effects often seen with other immune stimulation, according to researchers.

Researchers injected tiny amounts of two immune-stimulating agents into the mice’s tumors, leading to the “complete obliteration” of cancerous cells.

The vaccine worked on laboratory mice with transplanted mouse lymphoma tumors in two sites on their bodies.

When scientists injected one tumor site, they found tumors in the second, untreated site also went away.

The researchers said they saw similar results in mice with breast, colon and melanoma tumors.

“When we use these two agents together, we see the elimination of tumors all over the body,” said Ronald Levy, professor of oncology.

“This approach bypasses the need to identify tumor-specific immune targets and doesn’t require wholesale activation of the immune system or customization of a patient’s immune cells.”

Researchers said they plan a clinical trial to test the treatment in 15 human patients who have low-grade lymphoma.

If successful, Levy said the treatments could eventually eliminate the need for surgery to remove tumors.

“I don’t think there’s a limit to the type of tumor we could potentially treat, as long as it has been infiltrated by the immune system,” Levy said.

    There’s already a well known substance that causes apoptosis in cancer cells that grows like a weed…I bet that’s harder to patent though.

    Many substances cause apoptosis in cancer cells: naltrexone, disulfiram, methadone, vitamine C,
    vitamin B17, oxigen …etc. They are inexpensive and not that toxic as chemo is, so alternative medicine is using them to cure patients with cancer.

    Maby if Prof Ronald Levy makes an agreement with alternative institutions…As he has got inexpensive drug for cancer, it would be bad if all that research disappear…Even now, in this moment, there would be million of patients ready to take cancer vaccine, specially those with incurable cancer grade 4. And as Prof Levy is possessing potentialy cancer cure drug, it is very
    weird situation that people are dying of cancer while he is making trial on only 15 patients with
    low-grade lymphoma. It is also weird that oncologists are not asking for more curable and less
    toxic drugs than chemotherapy. They are very quiet. They are aplauding for chemotherapy that is
    prolonging life for few months and cost fortune. That is not a cure for cancer. Maby if prof Levy connect with alternative Institutions as his cancer vaccine is inexpensive, maby it could find
    it’s way to those who desperately need it.
