What do cancer cells and bears have in common? How is artificial intelligence changing cancer? How do ovarian cancer cells survive in hostile environments? Can CML patients stop taking their medication? Why are cancer death rates continuing to decline? What should cancer patients know about the Covid-19 vaccines? There are a lot of questions to answer this month. Fortunately, we have the answers.
Some of the most pressing questions cancer patients have are about the Covid-19 vaccines. Some of the answers can be found at curetoday.com, which has put together a list of some things you should know. There are currently two Covid-19 vaccines available in the United States. They were authorized by the Food and Drug Administration (FDA) in late 2020. The two vaccines made by Pfizer-BioNTech and Moderna both require two doses, and both have an over 90 percent efficacy rate after both doses are administered. Both vaccines trigger the immune system to react defensively to the SARS-CoV-2 virus without causing the virus. There are common side effects seen as a result of the vaccines that include tiredness, pain at the injection site, headache, muscle ache, and fever. The side effects can last for several days or a week. While cancer patients should discuss the vaccine options with their doctors, it’s important to note that getting the vaccine should not affect most cancer treatments. Find the complete comparison of the two vaccines, which includes an explanation of how each vaccine works and the common side effects specific to each vaccine, here. There is also a helpful and easy-to-read infographic.
Declining Cancer Death Rates
There’s no question that declining death rates are good news. As of 2018, cancer death rates are continuing to decline in the United States, reports abcnews.go.com. The rate has been falling since 1991, and from 2017 to 2018, it fell 2.4 percent. In the past five years, almost half of the decline in cancer deaths was attributed to lung cancer. With fewer people smoking, the rates of lung cancer illness and death have declined, and due to better treatments and diagnostics, people with lung cancer are living longer. While cancer remains the second leading cause of death, it’s encouraging that the death rates are continuing to decline. Learn more here.
A question CML patients could be asking their doctors is whether or not they can stop taking their medication. Some chronic myelogenous leukemia (CML) patients may not have to, reports cancer.gov. The tyrosine kinase inhibitors (TKIs) CML patients take to make the disease manageable are taken every day and they come with some disruptive side effects, which affect the quality of life for patients. However, a new clinical study shows that patients who were in remission for at least two years, and stopped using nilotinib, imatinib, and two other TKIs, had an improved quality of life, and about two thirds of the patients remained in remission three years after stopping treatment.

Researchers have long been questioning how ovarian cancer cells survive in hostile environments, but now have an understanding of how ovarian cancer cells survive and grow in the fluid of the abdomen, which should be a hostile environment of low nutrients and oxygen, reports eurekalert.org. The study looked at the structures inside the cells during different stages of ovarian cancer and found that one of the structures, the mitochondria, changed shape and function in the peritoneal cavity, the space in the abdomen that contains the intestines, liver, and stomach, which made it possible for aggressive cancer cells to flourish. Knowing how the cells are able to survive and thrive in the abdomen could help develop better treatments for the disease that may prevent the spread of cells from the original tumor to the peritoneal cavity. When ovarian cancer cells spread through the peritoneal cavity, a patient’s survival rate is just 30 percent. Learn more about the findings here.
AI Being Used in Cancer Care
Some researchers are answering the question of how artificial intelligence will play a role in the future of treating cancer. A new telescope developed at Rice University could be a game changer for cancer surgeries, says texasmonthly.com. Using artificial intelligence, it can take a lot of the guess work out of analyzing tissue and could save valuable time during surgeries. Find out how here.
Artificial intelligence is also being used to develop a technique to diagnose prostate cancer, reports phys.org. The technique is almost 100 percent accurate and can diagnose prostate cancer from urine within 20 minutes. This new technique is less invasive and much more accurate than current prostate cancer testing. Learn more about the development of the new technique here.
Finally, who isn’t asking what bears and cancer cells have in common? It’s hibernation, of course! Cancer cells can go into a type of hibernation as a means of surviving chemotherapy, reports scitechdaily.com. Research shows that cancer cells have the ability to become sluggish and enter a slow-dividing state of rest to protect themselves when threatened by chemotherapy or other targeted therapies. They hibernate, just like bears, until the threat is gone, and they can resume their normal state of growth. The information helps look at chemotherapy-resistant cancers and how to better treat them. The study also showed that cancer regrowth can be prevented when therapies target cancer cells in their slow-dividing state of rest. Learn more about hibernating cancer cells here.
