Targeted Cancer Drugs May Protect Fertility in Female Cancer Patients

There is New Hope for Cancer Patients.
There is New Hope for Cancer Patients to Have Children After Treatment

Women of child-bearing age who are undergoing cancer treatment are often vulnerable to infertility. Researchers recently discovered that a certain type of targeted cancer drug may block this unfortunate side effect of chemotherapy.

How Cancer Treatment Affects Fertility

Chemotherapy drugs work by targeting rapidly developing cells and damaging cellular DNA. Oocytes, or immature egg cells, are hypersensitive to DNA damage in order to “retain genomic fidelity.”

In addition, chemotherapy triggers a signaling pathway in the ovaries, resulting in premature maturation of primordial follicles. This process is often referred to as follicular burnout.

Currently there are two primary options for women to preserve their fertility while receiving chemotherapy:

• Goserelin (trade name Zoladex®) and leuprolide (trade name Lupron®) are drugs that temporarily shut down the ovaries.

• Cryopreservation involves harvesting eggs and freezing them for future use or fertilizing them outside the body and freezing the embryos.

Can Targeted Cancer Drugs Help to Preserve Fertility?

mTOR inhibitors have been approved for clinical use as they undergo continued testing for application as targeted cancer drugs. Since mTOR is a vital element in an ovary’s signaling pathway, researchers suspect that blocking the enzyme could protect the reserve of primordial follicles.

During the study, female mice who received chemotherapy only experienced follicular burnout, while those who received mTOR inhibitors as supplements maintained the reserves of primordial follicles. The latter also became pregnant at normal rates, while the former were primarily infertile.

Researchers have been focusing on CAR T-cells as the basis for a promising immunotherapy cancer treatment. Recent trials show encouraging results for the use of CAR T-cells in fighting advanced multiple myeloma.

CAR T Cells: A New Approach in Cancer Treatment

Scientists are excited about CAR T-cell therapy because it uses a patient’s own immune cells to treat cancer. The cells are gathered from the patient’s blood, engineered to produce chimeric-antigen receptors (CARs), and multiplied in the lab to reach quantities in the billions.

At that point, the cells are reintroduced into the patient’s bloodstream, to where they attach themselves to specific targets on cancer cells. CAR T-cell products, currently awaiting FDA approval, target the CD19 antigen in leukemia and lymphoma.

Can CAR T-Cells Treat Different Cancers?

Two CAR T-cell trials were recently conducted in the United States and China. Results were presented last June at the annual meeting of the American Society of Clinical Oncology in Chicago.

Both trials examined the use of CAR T-cells that target B-cell maturation antigens (BCMA), which are proteins found in myeloma cells. Most of the patients in the studies achieved positive results, with many experiencing complete remission.

CAR T-cell research is still in the early stages. Testing will continue to validate these findings and determine whether CAR T-cell therapy is a viable treatment method for cancer patients.

The Connection Between Tumors and Blood Vessels

The medical community has long believed that cancer cells support their growth by generating blood vessels. A recent study suggests that blood vessels may actually begin the cycle of tumor development.

“Hijacking” Blood Vessels for Tumor Development

According to cancer biologist Dr. Lan Ko, one of the authors of the study, the team found evidence that blood vessels can create tumors. In turn, the cancer cells then produce blood vessels to further sustain their growth.

Researchers focused on GT198, a gene generally found in low levels within the body. It has a natural ability to repair DNA and regulate stem cells, but in mutated form it creates cancer cells.

Pericytes, found in the outer layer of blood vessels, resemble stem cells in the way they can form different types of tissue. During the study, researchers found abnormally high levels of GT198 in pericytes supporting a number of human tumors.

Even more surprising was that the GT198 was located in the pericytes’ cytoplasm instead of the nucleus. This enabled malignant pericytes to multiply into cancer cells and detach from blood vessels to promote spread of the tumors.

Application for Cancer Treatment

As Dr. Ko explained, these results indicate that GT198 is a viable target for immunotherapy for cancer treatments. Further testing will explore use of existing cancer drugs and development of new ones.

How the Presence of Estrogen Protects Women from Gastric Inflammation Leading to Cancer

In the past, scientists have attributed gender discrepancies in cancer rates to lifestyle differences. Recent evidence strongly indicates that the cause may actually lie in biological differences instead.

This theory was bolstered by the results of an MIT study involving male mice infected with H. pylori, a bacterium that can lead to gastric cancer. More than 50 percent of people around the globe are infected with H. pylori, and while many remain asymptomatic, gastric cancer is the second-leading cause of cancer deaths worldwide.

How Gastric Cancer Develops

H. pylori infections are controlled by the body’s immune system, but a common side effect is gastritis, which is an inflammation of the stomach. The result is conditions that lead to the development of gastric cancer.

Studies have indicated that estrogen can protect women from gastritis, lowering their gastric cancer risk. Conversely, Tamoxifen and other drugs that block estrogen have been linked to higher risk of gastric cancer in women.

Testing the Theory

The mice in the MIT study were treated with estrogen, Tamoxifen or both. None of them developed cancer despite a prior history of gastritis, suggesting that Tamoxifen in the stomach may mimic rather than block estrogen. In the untreated control group, 40 percent of the mice developed gastric cancer.

Issels®: The Leader in Immunotherapy for Cancer

Using estrogen to treat cancer is an example of using the body’s own resources. Immunotherapy for cancer is a non-toxic way to boost the power of your own immune system to fight cancer.

Scientists Uncover a Key Step in Lung Cancer Progression Which May Lead to New Treatments

Approximately 40 percent of lung cancer cases in the United States involve an aggressive form called adenocarcinoma. Researchers recently identified a vital step in this cancer’s development that could be the key to successful early cancer treatment.

The Path from Benign to Malignant

Lung adenocarcinoma gets its name from adenomas, which are a form of benign tumors. Scientists believe that lung adenocarcinomas begin as adenomas that transition to the more aggressive type.

A team of researchers at MIT’s Koch Institute for Integrative Cancer Research set out to study the process behind the change from benign to malignant. According to lead author Tuomas Tammela, at some point the tumor cells begin acting like stem cells, allowing for rapid reproduction.

Flipping the Switch

Wnt is a signaling pathway that maintains cells in a stem cell-like state. The team focused on the activity of this pathway in a group of mice programmed to develop lung adenomas that were likely to progress to adenocarcinomas.

While they found that the Wnt pathway was not active in the adenomas, about five to 10 percent of the cells turned it on during the transition. When the mice received cancer treatment that interfered with the Wnt proteins, tumor growth was halted and the mice lived 50 percent longer.

Built to Spread, Cancer May Change Genome to Proliferate More Easily

Researchers already know that cancer cells are often able to evade detection by the body’s disease-fighting immune system. A recent study shows they may also streamline their genomes for faster replication.

The good news? This information can be used to predict whether a tumor will be vulnerable to DNA-damaging immunotherapy for cancer.

What Is Ribosomal DNA?

Ribosomal DNA, which is present in both healthy and cancerous cells, is the key. This DNA carries the code for ribosomes, which produce the proteins that are responsible for many cell functions.

Copies of these DNA sequences are subject to constant expansion and contraction. A research team at the Stowers Institute, led by Jennifer L. Gerton, Ph.D., set out to show that cancer cells would select for expansion for more rapid proliferation.

A Surprising Discovery

Amazingly, after examining DNA in normal and cancer cells in both humans and mice, the team discovered that the cancer cells held fewer copies of ribosomal DNA. Despite this fact, the cells were able to efficiently make more ribosomal RNA and synthesize more protein.

Dr. Gerton theorizes that less DNA to copy enables faster replication. The side effect of this downsizing is a greater sensitivity to DNA damage, which Dr. Gerton’s team demonstrated by treating the cancer cells with four different DNA-damaging drugs.
