A woman with an aggressive form of breast cancer which defied chemotherapy and spread to other organs, was cured with an experimental treatment that triggered her immune system, researchers said Monday.
The doctors treated the woman by injecting 80 billion of the carefully-selected immune cells into her body. Twenty-five percent of those patients won't qualify for chemotherapy because of age or medical problems. Now they can have confidence in those decisions, experts said.
A woman with advanced breast cancer which had spread around her body has been completely cleared of the disease by a groundbreaking therapy that harnessed the power of her immune system to fight the tumours. Generally, after surgery, such patients receive endocrine therapy, such as tamoxifen, which is created to block the cancer-spurring effects of hormones.
More than 20,000 women in the United Kingdom are diagnosed with hormone-receptor positive, HER2-negative, node-negative breast cancer annually.
The ground-breaking research was presented at the American Society of Clinical Oncology in Chicago on Sunday.
A high recurrence score, above 25, means chemo is advised to ward off a recurrence, while a low score, below 10, means it is not. Such patients have been in "the gray zone, and we haven't known what to tell them", Kurian said. After surgery, one group got endocrine therapy only, while the other was treated with endocrine therapy plus chemotherapy.
If your doctor told you you were low-risk and didn't need to have chemo, would you avoid it or still go through with it to eliminate the risk of the cancer spreading further?
Some benefit for chemotherapy was found in women aged younger than 50. Women younger than 50 still saw some benefit from chemotherapy, especially with scores between 21-25.
Bachini's initial surgery removed two-thirds of her liver, but three months later the disease showed up in her lungs.
But the best treatment for those with a score in the middle has been unclear. A chance meeting with a top NCI scientist prompted her to enroll in the trial in 2015. She got only tamoxifen.
"One of the challenges that we've had in breast cancer is we thought once size fit all, and everyone was getting too much treatment", Olopade said.
"The uncertainty is over", she said. "My brother was so sick that he'd be saying, 'I can't do this anymore, ' and it was the same thing with my sister".
These gene tests are only applicable to patients with early-stage invasive breast cancer, Loyola's Albain says.
Dr. Lisa Carey, a breast specialist at the University of North Carolina's Lineberger Comprehensive Cancer Center, said she would be very comfortable advising patients to skip chemo if they were like those in the study who did not benefit from it.
Oncotype DX first hit the market in 2004.
Yet the move away from chemotherapy has been hotly debated, with some doctors warning that chemo can save lives and that a "de-escalation" of treatment could be unsafe. He expects treatment guidelines to quickly change based on the study, which was conducted by a research group named ECOG-ACRIN. A little boost can outweigh the risks of the treatment for these patients.
Researchers share preliminary and more advanced results.
However, research published yesterday has suggested that more sufferers may be able to avoid chemotherapy treatment. "That's important because chemo is toxic, it whacks patients out and can result in long-term job loss".
But an immune breakthrough for bowel, breast and ovary cancer has remained elusive.
Researchers studied their outcomes, including whether or not cancer recurred, and their overall survival.
Still, massive well done to these brilliant doctors, and we hope Judy continues to live a long and happy hike-filled, cancer-free life.
While chemotherapy is being dropped for some cases, it's being increased for more aggressive cancers. "Now, we're not going to have to have that long discussion", she says. "No more, no less".
