Identification of Key Biological Pathway Primes Immune System to Fight Cancer

While immunotherapy cancer treatment has provided options for many patients, doctors are challenged by determining which patients will be most receptive. The recent discovery of a key biological pathway may prove to be a useful solution.

Stimulating the Power of the Immune System

Cancer cells often avoid the normal immune response by triggering the brake mechanism that keeps T cells from attacking healthy tissue. Immunotherapy drugs called checkpoint inhibitors override the brakes, but so far this treatment has been successful with a minority of patients.

In 2014, a research team at UC San Francisco discovered an element of the immune system called stimulatory dendritic cells (SDC), which help direct T cells to a target. The scientists also uncovered a correlation between low levels of SDCs and poor response to checkpoint inhibitors.

Creating a Receptive Environment for Immunotherapy

The team recently set out to learn why SDC levels vary among tumors. In this study, they found that natural killer (NK) cells in the immune system express a signaling protein known as FLT3LG. Presence of FLT3LG has a strong relationship to presence of SDCs.

While NK cells have long been recognized as a direct threat to cancer cells, the UCSF study demonstrates that they can also communicate with other immune cells. Scientists are hopeful that developing a way to increase the number of NK cells in a tumor will help more patients benefit from immunotherapy.

When it comes to your health, a virus is generally something to be avoided. In a surprising discovery, a virus that normally causes paralysis may hold promise as an immunotherapy for cancer treatment.

Can a Virus Actually Fight a Tumor?

Glioblastoma is the most common and most deadly form of brain cancer affecting adults. It gained a measure of public awareness after former Sen. Edward Kennedy and Beau Biden, son of former Vice President Joe Biden, succumbed to the disease. One year ago Sen. John McCain, already a cancer survivor, was diagnosed with glioblastoma.

Poliovirus, which causes the paralyzing disease that shares its name, infects cells in the nervous system. Based on this feature, a team of Duke University scientists decided to test a genetically modified version on patients with treatment-resistant glioblastoma.

Poliovirus and the Immune System: A Two-Pronged Attack

The researchers neutralized the virus by replacing the specific gene that causes polio with one from rhinovirus, which generally causes head colds. Once infused directly into the tumors, the newly formed virus was able to infect and kill cancer cells as well as stimulate the immune system to attack the cells.

According to team member Dr. Darell Bigner, the group’s 21 percent survival rate after three years is more than five times that of a previously treated comparison group. The researchers are planning to conduct studies combining the modified poliovirus with other immunotherapy for cancer drugs in hopes of improving the results.

Lymph Node Metastasis Uses Blood Vessel Pathways to Spread Cancer

Lymph node metastasis can have major implications for immuno oncology treatment. In a recent study, scientists examined the progression of metastatic tumor cells to learn more about how they are disseminated throughout the body.

Is Treatment of Lymph Node Metastases a Priority?

When cancer metastasizes in the lymph nodes, it’s generally a sign of an exceptionally aggressive tumor and a poor prognosis. Scientists differ on the treatment of lymph node metastases, with some experts believing it’s “clinically inconsequential” while others think they should be treated promptly to prevent distant metastases.

Results of clinical testing further complicate the issue. In one trial, removal of anything beyond the first lymph node had no benefit for patients who had received radiation and systemic therapies, while in another, lymph node treatment was found to help a subgroup of patients with breast cancer.

Tracing the Journey of Metastatic Cancer Cells

A team of researchers implanted a group of mice with cancer cells that expressed a photoconvertible protein known as Dendra2. This feature allowed scientists to photoactivate selected metastatic cells in the lymph nodes and follow their path.

Originally, metastatic cells were thought to travel by either blood vessels or the lymphatic system. In studying the affected mice, scientists determined that the metastatic cells followed a hybrid route by invading blood vessels within a lymph node, using it as a means of exit by which the cells could travel to the lungs and other organs.

Do you Have or Know Someone Who is Currently Experiencing a Hard to Treat Cancer? There is Hope!

When you receive a diagnosis of cancer, your mental and emotional adjustment can make a difference during your course of immuno oncology treatment. Unfortunately, most people have no frame of reference for coping with such news.

The American Cancer Society offers helpful tips for coming to terms with a cancer diagnosis and continuing to live life to the fullest.

Follow Your Own Path

Your situation is unique. Others may offer ideas of what has worked for them, but don’t feel obligated to follow them to the letter. View these tips as suggestions and try out different methods to find your own best solution.

Learn About Your Cancer

Knowledge is power. The unknown is often more frightening than the reality, so take time to educate yourself about your type of cancer and the various treatment options that are available.

Stay Active

The link between exercise and mood is well-documented. Physical activity stimulates production of endorphins, which are natural mood elevators. Consult with your doctor to make sure you’re not overdoing it.

Let Your Feelings Out

Many people believe that fear, anger and other negative emotions must remain hidden, but that can make your situation even harder to bear. Talk to friends and family, join a support group or try an artistic outlet such as writing or painting.

Be Kind to Yourself

Make a point each day of doing something that makes you happy, whether it’s meeting a friend for lunch or simply meditating for 15 minutes.

No two cases of cancer are the same, so scientists are finding that cookie-cutter cancer treatment is not always the best solution. According to a recently published study, a personalized vaccine has shown promise for boosting ovarian cancer survival rates.

Ovarian Cancer: The “Silent Killer”

An international team of researchers conducted the study of ovarian cancer, often referred to as a “silent killer” because it’s usually in an advanced stage by the time of diagnosis. Chemotherapy plus surgery is the conventional course of treatment, but team member Dr. Lana Kandalaft notes that 85 percent of patients experience recurrence.

Matching Cancer Treatment to Patient

Immunotherapy is a form of treatment that uses a patient’s own immune system to attack and kill cancer cells. In this case, researchers created a vaccine by harvesting a patient’s immune cells, then exposed them to cells from the tumor so they could be identified.

All patients in the study were treated with a combination of immunotherapy drugs, while a certain number also received the vaccine. After one year, the vaccinated group had a survival rate of 100 percent compared to 60 percent of the control group.

Results continued to be encouraging after two years. The vaccinated group showed a survival rate of 78 percent, while the rate dropped to 44 percent with patients receiving drugs alone.

Cancer Gets Fuel From Fat Cells – How to Starve Tumors

It's Time to Cross Out Cancer!
It’s Time to Cross Out Cancer!

Cancer research is now going beyond the genetic aspect to explore how the disease interacts with the body’s systems. Recent studies of the relationship between cancer and fat cells may have implications concerning immunotherapy for cancer.

Feeding the Growth of Cancer Cells

While the precise causes are not yet known, obesity has been identified as a risk factor for prostate cancer, which is the second leading cause of cancer-related deaths in men. As a result, research into the link between cancer and fat cells has focused on this form of the disease.

Previous tests involved mice who were fed a high-fat diet. In contrast, researchers at Sanford Prebys Medical Discovery Institute in San Diego conducted a study using mice who lacked a protein called p62, causing them to become obese on a normal diet.

According to co-author Dr. Jorge Moscat, this control was necessary to get a clear understanding of the communication pathways between cancer and fat cells. The team discovered that p62 suppresses another protein known as mTORC1, which in turn inhibits energy use by fat cells.

Can Cancer Cells Be “Starved” to Death?

With metabolism halted in fat cells, nutrients are then available to fuel development of tumor cells. Lack of p62 also triggers production of proteins found at high levels in particularly aggressive forms of prostate cancer.

As explained by Dr. Moscat, these findings can help identify specific substances to be targeted by immunotherapy for cancer treatments with the goal of “starving” cancer cells.
