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.

Scientists have embraced immuno oncology research as an avenue for more effective cancer treatments. Unfortunately, the field took a temporary hit recently when Incyte pulled the plug on its latest immunotherapy drug trial.

Arming the Body’s Immune System

Incyte had high hopes for epacadostat, which works as an IDO inhibitor. IDO is an enzyme found in the body that prevents T cells in the immune system from attacking cancer cells.

In the trial, epacadostat was paired with Keytruda, a phenomenally successful immunotherapy drug from Merck. Keytruda is a checkpoint inhibitor that helps T cells recognize cancer cells, which often evade detection.

It was hoped that epacadostat would boost the effectiveness of Keytruda when taken alone. But not only did epacadostat fail to stop the progression of cancer, it had no positive effect on overall survival rates.

Is There Still Hope for Epacadostat?

While the original trial failed against melanoma, Incyte is hoping to conduct further tests with epacadostat in treating other forms of cancer. As explained by Dr. Jason Luke, an oncologist at the University of Chicago, the patient sample may have been too broad.

According to Dr. Luke, immunotherapy benefits patients with T cell-inflamed tumors. The key is to test epacadostat on patients who have a natural immune response, which can be determined via RNA-based sequencing.

Yale University oncologist Dr. Roy Herbst says the setback will not affect the enthusiasm for immunotherapy. He emphasizes that these cancer treatments are not a one-size-fits-all solution.

Immunotherapy and Gastric Cancers – What to Know

Immunotherapy and Gastric Cancers
Immunotherapy and Gastric Cancers

Immunotherapy and other targeted methods have shown promise in effectively fighting gastric and gastroesophageal junction (GSJ) cancers. At a recent summit meeting, Dr. Andrew Ko, professor of medicine at the University of California, San Francisco, discussed cancer treatment for gastric and GSJ cancers as well as current challenges.

Checkpoint Inhibitors and Gastric Cancers

In terms of recent developments, Ko pointed to last year’s FDA approval of pembrolizumab as a turning point in the treatment of advanced cancers. Pembrolizumab (trade name Keytruda) is a checkpoint inhibitor used on cancers with positive expression of PD-L1, a protein that enables cancer cells to avoid attack by the immune system.

Ko also mentioned nivolumab (trade name Opdivo), another checkpoint inhibitor. Nivolumab is used for melanoma and lung cancers, but clinical trials have shown that it has potential as a secondary treatment following chemo-radiation and surgery for patients with certain GEJ cancers.

Unfortunately, cases of upper gastrointestinal cancers continue to rise in Western countries. Ko explained that, despite improvements in immunotherapy cancer treatment, many patients are still non-responders, creating continued urgency in finding additional methods.

The Future of Gastric Cancer Treatment

According to Ko, immunotherapy still holds the greatest interest for cancer researchers.

– Studies are exploring combinations of drugs, such as nivolumab plus ipilimumab (trade name Yervoy).

– Other studies are focused on moving targeted agents from secondary to first-line treatments.

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.

July is Bone Cancer Awareness Month – What to Know

Bone Cancer or Sarcoma is in the focus in July

What are the types of bone cancer? Can it be treated with immunotherapy for cancer programs? July is Bone Cancer Awareness Month, making it a good time to share some facts about the disease from the National Cancer Institute.

Basics of Bone Cancer

As the name implies, bone cancer is a malignant tumor that forms in bone tissue. The majority of bone tumors are benign, which means they’re non-fatal and don’t spread.

On the other hand, bone cancer CAN spread to other parts of the body. Regardless of the location of the metastasis, or spread, the disease is still referred to as bone cancer based on its original site.

Types of Bone Cancer

– Osteosarcoma, usually found in the knee or upper arm, develops in hard bone tissue.

– Chondrosarcoma forms in cartilage, which is the tough but resilient tissue that cushions joints.

– The Ewing Sarcoma Family of Tumors, or ESFTs, are thought to arise from primitive nerve tissue in bone or soft tissues.

Bone Cancer Symptoms

Chronic pain or swelling in or near a bone are the most common symptoms of bone cancer, but they could also be indicative of other conditions, so it’s important to be tested.

Treatments for Bone Cancer

Traditional treatments such as surgery and chemotherapy are often used with bone cancer patients. The NCI and other organizations also sponsor frequent clinical trials to investigate immunotherapy for cancer treatments.

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.
