Cancer Treatment and the Impact on Cognitive Ability

Effective cancer treatment sometimes involves dealing with side effects and secondary symptoms. Here are some things you need to know about the possible effects of cancer and its treatment on cognitive abilities.

What Is Cognition?

Simply put, cognition is “the mental process of learning and understanding.” Cognitive thinking is what allows you to focus, process new information, solve problems, perceive spatial relationships and communicate via speaking and writing.

Cognitive Problems Related to Traditional Cancer Treatment

Problems involving learning and memory are common signs of cognitive impairment due to cancer. Specific problems can include:

– Inability to complete tasks

– Failure to recognize familiar objects

– Loss of focus and concentration

– Difficulty with money management, such as paying bills

– Lack of motivation

– Disorganized behavior and/or thinking

Other Factors Contributing to Cognitive Problems

States of mental and physical well-being are deeply intertwined. Cancer patients and survivors may find that the following issues also impact cognitive abilities:

– Age

– Overall weakness or frailty

– Drug and alcohol use

– Chemotherapy and other cancer treatment

– Other diseases or illnesses

– Being postmenopausal

Restoring Cognitive Abilities After Cancer Treatment

Researchers are studying the use of certain drugs in treating cognitive problems, but a pharmaceutical solution is still in the future. Many patients have found these natural methods to be helpful:

– Movement therapy, such as tai chi or yoga, that emphasizes the mind-body connection

– Learning new ways to absorb information

– Using calendars, tech devices or other tools to stay organized

– Activities such as gardening or caring for pets that establish focus

Genetic Testing Identifies Best Immunotherapy Prospects for Prostate Cancer Patients

While immunotherapy has proven to be a viable form of cancer treatment, not all patients respond to the currently available methods. A major breakthrough occurred this summer, when scientists found that genetic testing could identify prostate cancer patients who are likely candidates for immunotherapy.

Treating Prostate Cancer with Immunotherapy

Last June, a major clinical trial provided the first evidence that advanced prostate cancer could be successfully treated with an immunotherapy drug called pembrolizumab. Approximately ten percent of patients responded, so the question became how to determine which patients to treat.

A possible answer came in the form of a study recently published in Cell. Scientists from London’s Institute of Cancer Research and the University of Michigan joined forces to analyze tumor DNA collected from 360 men with advanced prostate cancer in various countries.

Is Genetic Testing the Solution?

Results indicated that seven percent of the tumors lacked a gene called CDK12. This feature is a hallmark of a unique genetic pattern that contains a greater amount of immune cells than other types of advanced prostate cancer.

In addition, these tumors had more neoantigens, which are proteins that alert the immune system to the presence of cancer cells. Thanks to the higher numbers of immune cells and neoantigens, the immune system already begins to recognize the tumor, which is why scientists think such tumors are more receptive to immunotherapy.

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 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.
