A single administration of a drug could potentially eliminate cancer.

Hope for cancer patients just got a nudge forward with a novel treatment developed by researchers. These scientists have designed an aimed injection that has wiped out tumors in mice test subjects.
Cancer research has experienced a boom in recent years, bringing forth new possibilities for a myriad of cancer types. Some of the latest experiments feature sophisticated nanotechnology to hunt down microscopic tumors, engineered microbes for cancer cell suppression, and starving malignant tumors to oblivion.
The Stanford University School of Medicine, California has pioneered the latest approach: injecting minute amounts of two immune-response accelerators directly into a solid tumor. So far, the research team's experiments with mice have shown promising results.
Dr. Ronald Levy, the study's senior author, explains, "This method eliminates tumors all across the body when we use these two agents together." The method sidesteps the need for locating tumor-specific immune targets and wholesale immune system activation.
The researchers anticipate quicker progress towards clinical trials for this method as one of the involved agents is already approved for human therapy, while the other is already being tested in lymphoma treatment clinical trials. They disclosed their findings in the journal Science Translational Medicine on yesterday's publication date.
The One-Shot Breakthrough
Dr. Levy, an expert in immunotherapy for lymphoma treatment, stated that various types of immunotherapy usually come with drawbacks, such as side effects, time implications, or high costs. The researchers' method, however, seemingly features more advantages, including potential effectiveness as a cancer treatment, as well as speedier clinical trials.
Dr. Levy states, "Our approach utilizes a one-time application of minuscule amounts of two agents to stimulate immune cells within the tumor only." This method supposedly trains immune cells to fight against the specific type of cancer they've been exposed to, allowing them to migrate and wipe out other tumors.
Cancer cells often evade the immune system’s detection and elimination, but immune cells called T cells can usually target and destroy cancer tumors. Cancer cells, however, frequently trick T cells into ignoring them.
Fighting a Variety of Cancers
The new study first applied the team's method to a lymphoma mouse model, and nearly all mice were cancer-free after treatment. Even in the three remaining cases where tumors regrew, a second treatment successfully eliminated them. Encouraging results were also obtained in mouse models for breast, colon, skin, and spontaneously developing breast cancer.
The scientists faced a mixed outcome when they injected two different tumor types – lymphoma and colon cancer – in the same animal but only treated the lymphoma site with the experimental formula. While all the lymphoma tumors receded, the colon cancer tumor did not respond.
Dr. Levy points out, "Our approach is very precise. Only the tumor with the protein markers matching those of the treated site is targeted. We're directly attacking specific protein targets without needing to pinpoint exact proteins that the T cells are identifying."
Currently, the researchers are readying a clinical trial to assess this treatment's effectiveness in individuals with low-grade lymphoma. If successful, they plan to extend this therapy to a wide range of human cancer tumors. As Dr. Levy concludes, "I foresee no limitations in the type of tumor we could potentially treat, as long as it has attracted the attention of the immune system."
- The novel treatment developed by researchers at Stanford University School of Medicine involves a targeted injection of two immune-response accelerators directly into a solid tumor, shows promising results in eliminating tumors across the body.
- This method, when used together, avoids the need for locating tumor-specific immune targets and comprehensive immune system activation.
- The researchers anticipate quicker progress towards clinical trials, given that one of the involved agents is already approved for human therapy, and the other is being tested in lymphoma treatment clinical trials.
- In the new study, the method was first applied to a lymphoma mouse model and showed near-complete effectiveness, with only three cases of tumor regrowth, which were successfully eliminated with a second treatment.
- Encouraging results were also observed in mouse models for breast, colon, skin, and spontaneously developing breast cancer.
- However, when the researchers injected two different tumor types – lymphoma and colon cancer – into the same animal and treated only the lymphoma site with the experimental formula, the colon cancer tumor did not respond.
