Personalized Immunotherapy: The Future for Cancer Treatment One Story

Immunotherapy is Changing Cancer Treatment Again in Exciting New Ways
Immunotherapy is Changing Cancer Treatment Again in Exciting New Ways

At Issels®, we recognize that successful cancer treatment is designed for a patient’s individual needs. This immunotherapy approach recently saved the life of one woman whose recurring breast cancer was spreading to other parts of her body.

“Two to Three Months to Live”

In 2003, Judy Perkins of Port St. Lucie, Florida underwent a mastectomy after being diagnosed with breast cancer. Just over two years ago the cancer returned, resulting in tennis-ball-sized tumors throughout her torso, including the lymph nodes.

This time around, Perkins was treated by Dr. Steven Rosenberg and his team at the National Cancer Institute. Rosenberg’s career has been devoted to the field of immuno-oncology, which involves finding ways to help the body’s own immune system attack and destroy cancer cells.

Weaponizing the Immune System

Rosenberg and his team began by obtaining samples of the tumors to sequence DNA and analyze tumor-fighting immune cells called lymphocytes. The scientists were then able to identify the specific gene mutations that allowed cancer cells to multiply and spread.

After determining which lymphocytes were most effective against the mutations, the team grew those cells in the lab and re-introduced them to Perkins’ system. In addition to doses of interleukin 2 and an immunotherapy drug approved by the FDA in 2017, Perkins received one last round of chemotherapy.

All tumors disappeared, and Perkins remains cancer-free today. Rosenberg is optimistic that this success will propel immunotherapy research to more breakthroughs.

Autoimmune Disease May Hold a Key for More Effective Immunotherapy Treatments

Research is Under Way to Cross Out Cancer
Research is Under Way to Cross Out Cancer

Thanks to their ability to avoid detection by the immune system, cancer cells are able to rapidly reproduce and spread. In a major breakthrough, scientists have discovered that a gene associated with hair loss could provide valuable clues to improve immunotherapy for cancer.

Autoimmune Disease: The Other Side of the Coin

Ironically, a research team at Columbia University Irving Medical Center (CUIMC) turned to the autoimmune disease alopecia areata as the topic of their recent study, published last June in Cell Systems. While cancer is marked by failure of the immune system, alopecia represents the opposite situation, an immune system in overdrive.

Alopecia results in immune cells attacking and destroying healthy hair cells. During previous research, the CUIMC team isolated a gene called IKZF1 that causes overproduction of T cells in the immune system.

“Flipping the Switch” on the Immune System

In the latest study, the scientists demonstrated that IKZF1 is turned off in many cancer cells. The team then set out to test their theory that activating IKZF1 would trigger T cells to begin attacking tumors.

The study broke down into two parts:

– When a mouse model of melanoma was engineered to express IKZF1, the corresponding tumors revealed increased levels of immune cells.

– Analysis of data from a previous study of melanoma patients showed higher recurrence in those with disabled IKZF1.

Lung Cancer Numbers Rise in Female Non-Smoking Populations

As the most common form of the disease worldwide, lung cancer is a primary target of immunotherapy for cancer research and testing. Unfortunately, scientists are alarmed at the rising incidence of lung cancer in women and non-smokers.

Non-Smokers Are Not Immune to Lung Cancer

The link between tobacco and lung cancer is well-known, leaving many people to mistakenly believe that only smokers will develop the disease. The facts are that approximately 15 percent of lung cancer cases are non-tobacco-related.

This anomaly is especially pronounced among women. Studies show that 20 percent of women who are diagnosed with lung cancer are lifelong non-smokers, compared to only 10 percent of men. Data from the U.K. reveals that, among patients undergoing lung cancer surgery over a six-year period, women made up 67 percent of the group that had never smoked.

Lung Cancer and the Gender Gap

In another dubious distinction, lung cancer rates in women have risen over the last 20 years, even as they’ve fallen in men. Researchers attribute this development to two possible causes:

– There is some evidence that women’s DNA is more vulnerable to damage caused by carcinogens contained in tobacco.

– At one time, smoking among women was relatively rare. Gains in gender equality appear to have resulted in more women taking up the habit.

Scientists urge anyone who experiences symptoms such as unexplained coughing, chest pains and shortness of breath to see their doctor, even if they’ve never smoked.

Test on New Drug that Contains Cancer Cell Metastasis

Tests on New Drugs That May Provide Better Treatment
Tests on a New Drug That May Contain the Spread of Cancer

At Issels®, our immunotherapy for cancer treatments are often used with patients whose tumors have spread to other parts of the body. Over the last few years, an international research team has made significant progress in developing a drug that limits the movement of cancer cells.

Stopping the Spread of Cancer Cells

Metastasis is the term for the ability of cancer cells to move throughout the body and establish tumors in locations away from the primary site. Once a tumor metastasizes, it presents a greater challenge for successful treatment.

While cancer research primarily focuses on treating tumors directly, a multinational team of scientists decided to investigate possible methods of interfering with cancer cells’ motility. If migration could be contained, it would help prevent tumors from entering later, hard-to-treat stages.

KBU2046: Putting the Brakes on Metastasis

In 2011, the team identified a drug called KBU2046 that binds to heat-shock proteins found in all cells, preventing cell movement. Original testing was done on human cell models of breast, prostate, lung and colon cancer in vitro.

The team’s most recent study, published in June, extended testing to mouse models. Scientists were able to confirm that KBU2046 targeted cancer cells only, sparing healthy tissue, and further refinements eliminated any side effects.

The researchers believe that the positive results justify their unorthodox approach. Next step on their agenda is obtaining funds to conduct further studies in preparation for clinical trials.

Special Adoptive T Cell Therapy Reprograms Metabolism of Cancer Cells Causing Their Death

“Everything in moderation” is often cited as the key to balance in life, but scientists are taking a different approach in a new form of cancer treatment. According to the results of a recent study, driving up levels of oxidative stress can be fatal to cancer cells.

Reprogramming the Metabolism of Cancer Cells

Reactive oxygen species (ROS) such as peroxide and superoxide are natural byproducts of the metabolism of oxygen, and they play a role in certain cell functions. But while high levels of ROS can kill normal cells and damage DNA, energy-hungry cancer cells consume greater quantities of ROS.

In a study published in Cell Metabolism, a research team at Augusta University examined the effects of adaptive T cell therapy on the metabolism of cancer cells. Testing was conducted on mice with large colorectal tumors.

When Oxidative Stress Becomes Fatal

Adoptive T cell therapy followed treatment with a chemotherapy drug that boosted the activity of the infused T cells. Nearly all the mice experienced complete tumor regression as an apparent result of two factors:

– Treatment interfered with production of an antioxidant called glutathione, causing ROS levels to rise.

– T cells increased production of proinflammatory cytokines, chief among them tumor necrosis factor alpha, making cancer cells even more vulnerable to oxidative stress.

Dr. Gang Zhou, author of the study, expressed hope that these findings will help improve immunotherapy treatments by making it easier for T cells to target tumors.

Identification of Key Biological Pathway Primes Immune System to Fight Cancer

It’s Time to Stop 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.
