Big strides in cancer outcomes
Some cancers remain incredibly difficult to treat, but generally speaking, new drugs are improving overall survival rates across most cancer indications.
A big advance in immuno-oncology
One of the biggest recent advances in cancer treatment could be the approval of a class of drugs called programmed cell death protein-1 (PD-1) inhibitors. These drugs keep cancer cells from hijacking the PD-1 pathway that's used by healthy cells to tell the immune system's T cells to leave them alone.
Keeping cancer cells from repairing themselves
Drugs targeting poly (ADP-ribose) polymerase (PARP) are also helping patients battle back more effectively against cancer. An enzyme, PARP helps repair damaged DNA in cells, and while that's a good thing in healthy people, it can be bad news for cancer patients.
Gene therapy: the next big thing
PD-1s and PARPis are exciting new drugs, but it's gene therapy that may deliver the biggest improvement in mortality in the coming decade.
The quest for a cure
PD-1 drugs, PARPis, and gene therapies offer new hope to high-risk patients. Their use puts us steps closer to turning cancer into a chronic disease. The Holy Grail of cancer drug development, however, would be a functional cure.
What is the treatment for breast cancer?
Sir Geoffrey Keynes describes the treatment of breast cancer with breast-sparing surgery followed by radiation therapy . After surgery to remove the tumor, long needles containing radium are inserted throughout the affected breast and near the adjacent axillary lymph nodes.
How much did helical CT reduce lung cancer?
Initial results of the NCI-sponsored Lung Cancer Screening Trial (NLST) show that screening with low-dose helical computerized tomography (CT) reduced lung cancer deaths by about 20% in a large group of current and former heavy smokers.
How many types of cancer are there in the human body?
Researchers from The Cancer Genome Atlas (TCGA) project, a joint effort by NCI and the National Human Genome Research Institute to analyze the DNA and other molecular changes in more than 30 types of human cancer, find that gastric (stomach) cancer is actually four different diseases, not just one, based on differing tumor characteristics. This finding from TCGA and other related projects may potentially lead to a new classification system for cancer, in which cancers are classified by their molecular abnormalities as well as their organ or tissue site of origin.
When was tamoxifen approved?
1978: Tamoxifen. FDA approves tamoxifen, an antiestrogen drug originally developed as a birth control treatment, for the treatment of breast cancer. Tamoxifen represents the first of a class of drugs known as selective estrogen receptor modulators, or SERMs, to be approved for cancer therapy.
How can cervical cancer be detected?
George Papanicolaou discovers that cervical cancer can be detected by examining cells from the vagina under a microscope . This breakthrough leads to the development of the Pap test, which allows abnormal cervical cells to be detected and removed before they become cancerous.
Why does prostate cancer regress?
Charles Huggins discovers that removing the testicles to lower testosterone production or administering estrogens causes prostate tumors to regress. Such hormonal manipulation—more commonly known as hormonal therapy—continues to be a mainstay of prostate cancer treatment.
What is the gene that causes cancer in chickens?
Michael Bishop, and Peter Vogt discover that the DNA of normal chicken cells contains a gene related to the oncogene (cancer-causing gene) of avian sarcoma virus, which causes cancer in chickens. This finding eventually leads to the discovery of human oncogenes.
What are the research developments that have the potential to transform the treatment of cancer?
Cancer treatment is evolving rapidly. New techniques can identify and target tumor vulnerabilities while leaving healthy cells alone. Immunotherapy can harness the body’s immune system to fight cancer.
What is the purpose of DNA changes in metastatic cancer?
More aggressive and metastatic cancers shed more DNA, and changes in the amount of DNA detected over time can be used to gauge disease progression and response to treatment.
What is the bispecific T cell engager?
So Maus and her colleagues gave the engineered T cells an extra gene that produces a T-cell engaging antibody-like molecule—more commonly known as a bispecific T-cell engager (BiTE)—that links T cells and their cancer targets.
What cancer did Maus work on?
Maus’s team is working on so-called armored CARs that attack glioblastoma, the deadly brain cancer that killed President Joe Biden’s son Beau. These modified T cells are designed to target a specific mutation that is found only on glioblastoma cells. But the CAR-T cells alone failed to do the trick.
Is it possible to test for cancer?
Testing tumors directly is not always feasible— for example, because enough tumor tissue may not be available. Moreover, ongoing monitoring would require multiple invasive biopsies. Drawing blood is much less invasive, and blood is rich in DNA—some of which comes from cancer cells.
Does immunotherapy work for cancer?
Immunotherapy can harness the body’s immune system to fight cancer. But new treatments still don’t work for everyone.
Can you teach your body to recognize cancer?
You could do it for deeper tumors, like pancreatic cancer or lung cancer, but it’s trickier,” Brody says. “If a person has cancer throughout their body, you only have to teach the immune system to recognize it at one site, and then the immune cells can travel around the whole body to get rid of cancer everywhere.”.
Why is there a fifth category of cancer?
There is now a fifth category, because researchers overcame a fundamental challenge. In the past, they couldn't recruit the body's own immune system to fight cancer. But, today, they can. And that is thanks to the research of Jim Allison, today's Nobel Prize winner and chairman of immunology at the University of Texas MD Anderson Cancer Center, who joins me now from New York.
Who won the Nobel Prize for immunotherapy?
But there is now a fifth category -- immunotherapy -- thanks to the revolutionary research of Jim Allison and Tasuku Honjo, who won the 2018 Nobel Prize in Medicine on Monday. Allison joins Nick Schifrin to discuss his research and his personal connection to fighting the disease.
What are T cells?
T cells, basically the immune system's soldiers, so to speak.
How long do you live with melanoma?
Well, I use that cautiously. But, in the case of melanoma, about 22 percent of people — and this is a study of thousands of patients of whom — for whom there's 10 years follow-up — about 22 percent of patients with late-stage melanoma, for which the prognosis, the survival was about 11 months after diagnosis when we started this work, about 22 percent, again, after a single dose are alive 10 years later.
Who is Jim Allison?
Jim Allison, an American research scientist, and Tasuku Honjo from Japan, helped create a revolutionary cancer treatment that continues to save lives.
Does PD-1 work against cancer?
But we know now that this drug works against many types of cancer. And PD-1 and the combination work against many kinds of cancer, including not just melanoma, but lung cancer, and Hodgkin's lymphoma, kidney cancer, bladder cancer, the head and neck. The list goes on and on.
What was the first test to prove the immune system was better than the one used for cancer?
It also kicked off the search for newer, better immune checkpoints. The first to be discovered was called PD-1.
What is the name of the drug that Jimmy Carter used to treat cancer?
For many people, “that Jimmy Carter drug”, the anti-PD-1 drug pembrolizumab, approved in 2015 and sold as Keytruda, was the first and only thing they’d heard about cancer immunotherapy. Keytruda is currently one of the most widely used of the new class of drugs, approved for use against nine different types of cancer in the US, and a smaller number in the UK, and that list is growing rapidly, as is the number of acronyms for the dozens of new checkpoints being tested. The immune system remains the deep ocean ecosystem of the human body. We’ve barely begun to plumb its depths.
What is the second generation of checkpoint inhibitors?
In December 2015, the second generation of checkpoint inhibitors (called anti-PD-1 or anti-PD-L1, depending on whether they’re blocking the T-cell or tumour side of the handshake) was used to unleash the immune system of Jimmy Carter and clear an aggressive cancer from his liver and brain.
How did penicillin help cancer?
For researchers such as Chen and others, this is our penicillin moment in the war on cancer. As a drug, penicillin cut infection rates, cured some bacterial diseases and saved millions of lives. But as a scientific breakthrough, it redefined the possible and opened a fertile new frontier for generations of researchers.
How many people died from cancer in 2018?
According to the World Health Organisation’s international agency for research on cancer, that translates to 9,055,027 deaths worldwide in 2018 alone. Our usual defence against disease is our immune system.
How many people will be diagnosed with cancer in their lifetime?
It’s estimated that nearly 40% of us will be diagnosed with cancer in our lifetimes and, until very recently, we’ve had three basic options for dealing with that news. We’ve had surgery for at least 3,000 years. We added radiation therapy in 1896. Then in 1946, chemical warfare research led to the use of a mustard gas derivative to poison cancer cells and the advent of chemotherapy. More recently, we also started poisoning cancer through drugs that attempt to starve tumours of nutrients or blood supply.
Why did Jim Allison's breakthrough happen?
For 100 years, the reasons behind that apparent failure were a mystery. Jim Allison’s breakthrough was the realisation that the immune system wasn’t ignoring cancer. Instead, cancer was taking advantage of tricks that shut down the immune system.
How to stop cancer?
You know you should cut down on fatty foods, be more active, and limit the alcohol you drink. These everyday tips are also good ways you can stave off cancer.
How to live better after cancer treatment?
Drug-free therapies like yoga, massage, meditation, and hypnosis can help you live better during your cancer treatment. Some relieve stress and help your mood. Others may make the side effects caused by chemotherapy or radiation a bit easier to take.
What does a scan tell you about cancer?
A scan tells your doctor if you have proteins that are helping your cancer cells grow. If you do, they can prescribe treatment that may block the growth. Thanks to better imaging, other high-tech tools can kill tumors. For instance, doctors can use a technique called cryoablation (freezing) to treat them.
Why is imaging important for doctors?
Advances in imaging may make it easier for doctors to learn about the cancer they’re up against. Studies are ongoing to learn more about these imaging techniques and to learn about the cancer they’re up against.
What is the name of the drug that is used to treat acute lymphoblastic leukemia?
Right now, the drug, called tisagenlecleucel ( Kymriah) is approved for treatment of children and young adults up to age 25 with B-cell acute lymphoblastic leukemia who haven’t gotten better with other treatments. But scientists are working on a version of CAR T-cell therapy for adults and for other kinds of cancer.
Why is cancer so hard to fight?
One thing that makes cancer tough to fight is that its cells can dodge your immune system. Your body either doesn’t see them as threats, or it simply can’t work hard enough to fight them.
What is car T cell therapy?
Many more drugs are in the works. The FDA has approved a form of gene therapy called CAR T-cell therapy. It uses some of your own immune cells, called T cell s, to treat your cancer. Doctors take the cells out of your blood and change them by adding new genes so they can better find and kill cancer cells.
