Times Insider delivers behind-the-scenes insights into how news, features and opinion come together at The New York Times. In this story, the science reporter Denise Grady provides human backstory about her article about a woman who, remarkably, recovered from colon cancer after treatment with cells from her own immune system.
I’ve been meeting more and more people with cancer lately who would be desperately ill — or worse — had they not taken matters into their own hands and found their way into clinical trials in which they received experimental treatments that put the disease in remission.
There were no guarantees. New treatments don’t always work, and experiments have risks. The patients I met are here to tell their stories because they’re among the lucky few, the successes. Still, the cancer landscape does seem to be brightening, if only just a bit, in large part thanks to immunotherapy, which includes various treatments that help the patient’s own immune system to fight cancer.
The latest good news from the cancer front came last week, from Celine Ryan, a 51-year-old woman from Rochester Hills, Mich., a suburb of Detroit. She homeschools her five children, the youngest of whom is seven years old. Ms. Ryan has colon cancer, and two years ago, doctors found that despite surgery, radiation and chemotherapy, the cancer had spread and invaded her lungs, where scans detected 10 tumors.
Ms. Ryan is an engineer and database programmer, and to her scientific mind, it seemed highly unlikely that more chemo would control the disease. Chemo made her sick the first time around, and she had every reason to belief it would do so again. She and her husband, who is also an engineer, agreed that she should forgo chemo and instead try to tap into a major research center for help.
“I remembered that I had read about another cancer patient, Melinda Bachini. It stuck in my brain,” Ms. Ryan said. “I found out about this trial she did, and I said, ‘That’s what I want to do.’”
A front-page article I wrote in May 2014 about Ms. Bachini, a paramedic in Billings, Mont., might have been the article that Ms. Ryan remembered. Ms. Bachini had a deadly cancer, cholangiocarcinoma, that had started in her bile duct; Ms. Bachini underwent surgery and several grueling rounds of chemo, but the cancer nontheless spread to her liver and lungs. In April 2012, her life expectancy was a matter of months. Ms. Bachini, 43 at the time, had six children and, like, Ms. Ryan, did not think further chemotherapy would help.
Instead, she combed the internet looking for clinical trials and came upon one, run by Dr. Steven A. Rosenberg, at the National Cancer Institute, that made sense to her.
She was accepted into the study, and got very lucky. Dr. Rosenberg’s team found that she had a type of cancer-killing immune cell that could destroy her tumors without harming normal cells. The researchers multiplied those cells in the lab and dripped more than 100 billion of them back into her. Ms. Bachini’s tumors melted away.
Inspired by Ms. Bachini’s story, Ms. Ryan called the cancer institute. She was deferred twice because her tumors were not big enough to yield enough immune cells. But she persisted, and even sent the researchers screen shots from her scans, with measurements of tumors that she and her husband thought met the trial criteria. Eventually, she was accepted into the study and, like Ms. Bachini, was one of the fortunate ones: Now, thanks to the cell treatment and surgery, she is cancer-free.
Ms. Ryan’s case made medical history, because it was the first time researchers found cells that could attack a common cancer causing mutation — a finding that may help thousands of other patients with the same mutation.
In November 2015, after the first scan showed that her tumors had shrunk markedly, Ms. Ryan tracked down Ms. Bachini and emailed her. “Call me!” Ms. Bachini replied. Ms. Bachini and Ms. Ryan have been friends ever since and stay in touch by phone and on Facebook.
“When Celine and I connected, I was so unbelievably happy for her,” Ms. Bachini said.
They hope to meet in person, maybe by coordinating their checkups at the cancer institute. Both try to help other patients who are looking for help and considering clinical trials.
Ms. Bachini needed more treatment recently, because tumors in her lungs began to grow again. She had surgery and was given an immunotherapy drug, a type called a checkpoint inhibitor, which has begun shrinking the tumors.
“I spend a lot of time talking to patients, doing cancer advocacy stuff,” Ms. Bachini said. “It’s how I can pay it forward.”

The emotions of hair loss during cancer treatment

By Sheryl M. Ness, R.N. April 3, 2015
Many times when I meet with cancer survivors, we discuss the side effects of treatment. This includes both physical and emotional effects. If a person is receiving chemotherapy or radiation, hair loss may be a common side effect. For many people, losing their hair can have an emotional impact that they (and others) are not expecting.
Hair loss may be one of the most obvious signs that a person is having treatment for cancer. I have had many survivors tell me that when they started losing their hair, it made the cancer real to them and others around them.
One woman told me that first she cut her long hair shorter, followed by shaving her head in anticipation of losing her hair during treatment. She said the first hair cut had a much more emotional impact than she expected. Later, when her hair was gone, she said that it made her feel like she had no control — she felt vulnerable and exposed. She had shared her cancer diagnosis with those close to her, but now it was obvious to anyone who saw her that she was dealing with cancer.
Another woman decided to face the hair loss directly by using humor and social media. After she shaved her head, she quickly got her friends and family involved. She posted photos of herself with various wigs and had people vote on their favorite. She found support in the fact that she was open about her experience with others and even had some fun. In this way, she had some control over the situation. She was actively dealing with the hair loss by talking about it with her friends and family.
Fortunately, hair loss from cancer treatment is usually temporary. Hair loss may start within two to four weeks of beginning treatment; regrowth may start about three to six months after treatment ends. At times, the first hair growth you experience may be a different color or texture, with eventual return to your normal.
If you are a survivor dealing with hair loss, ask about local resources that provide hats, scarves and wigs to cancer patients. The American Cancer Society partners with the Personal Care Products Council and the Professional Beauty Association to offer "Look Good…Feel Better" programs for women, men and teens. For more information, call 1-800-395-LOOK (5665) or visit their website (www.lookgoodfeelbetter.org). This free program helps cancer survivors discover ways to deal with skin changes using cosmetic and skin care products, as well as hair loss by learning about scarves, wigs and other accessories.

Triple-negative breast cancer: 

Nanodelivery of new drug shows promise

MNT Knowledge Center
Published: 

Using nanoparticles to deliver an experimental drug directly into 
triple-negative breast cancer cells could be an effective way to 
fight this very aggressive cancer, which has very few treatment options. 
The drug is a peptide that is unstable, and delivering it directly into cells 
means that it can reach its target before degrading.

The researchers hope that their nanodelivery method will lead to new treatments for triple-negative breast cancer - a particularly aggressive cancer that currently has very few treatment options.
So concludes a study led by Mohamed El-Tanani, a professor in the Institute for Cancer Therapeutics at the University of Bradford in the United Kingdom. He and his colleagues report their findings in the International Journal of Pharmaceutics.
The new drug - discovered by El-Tanani - is a protein fragment, or peptide, that blocks a cell-regulation protein called RAN, which promotes cancercell division and proliferation.
The researchers note that high levels of RAN are linked to aggressive tumor growth and spread (metastasis), resistance to chemotherapy, and poor outcomes in several cancers, including triple-negative breast cancer.
Around 10-20 percent of breast cancers are diagnosed as triple negative.
The term "triple negative" means that tumors test negative for the three most common receptors that drive the majority of breast cancers: human epidermal growth factor receptor 2, progesterone receptors, and estrogen receptors.

Nanoparticle capsule prevents degrading of unstable peptide

The lack of all three receptors limits the options for treating this highly aggressive cancer, resulting in poorer outcomes for patients and an increased risk of recurrence.
The new study builds on previous work by Prof. El-Tanani and colleagues, in which they showed that blocking RAN can prevent and perhaps even reverse chemotherapy resistance in small cell lung cancer.
When they ran tests in the laboratory, the researchers found that the drug was not as effective as predicted using computer models of cell processes, as Prof. El-Tanani explains:
"We knew we'd need a novel delivery mechanism for this drug because peptides on their own are unstable and they can degrade too quickly to be effective. Using a nanoparticle as a delivery mechanism was the perfect solution."
Medical researchers are increasingly turning to nanotechnology to develop new treatments because it allows them to work with and control molecules at a scale that is smaller than cells.

Two thirds of cancer cells died within 24 hours

For the new study, the team used a biodegradable polymer to make a nanoparticle that encapsulates the peptide. They tested a number of materials before they found one that effectively sustained the integrity and stability of the peptide.
When they tested nanoparticles charged with the peptide on triple-negative cancer cells in the laboratory, the researchers found that the cells actively took them in, reduced their growth rate, and stopped replicating. Within 24 hours, around two thirds of the cells were dead.
Adding either the peptide on its own, or the nanoparticle without the peptide load, had no such effects.
On closer examination, the researchers found that the peptide was killing the cancer cells in the same way as the computer models predicted - it was preventing RAN activation by silencing a gene called regulator of chromosome condensation 1, or RCC1.
The Bradford team is already testing the nanoparticle delivery method in a model of triple-negative breast cancer and considering how to progress toward clinical trials.
They are also looking at other RAN inhibitor candidates. One of these is a "repurposed" drug that they say has passed preclinical tests of breast and lung cancer and is ready for clinical trials, for which they are seeking funding.

"By developing a nanoparticle that can help this peptide enter triple-negative breast cancer cells and block RAN we've brought this potential new treatment a step closer to the clinic."

VR provides distraction therapy for chemo patients

Individuals with cancer experience many anxiety-filled moments over their course of treatment. In order to alleviate some of this stress, one Australian hospital is using virtual reality to provide a therapeutic degree of relaxation and escapism to its chemotherapy patients.
Chris O'Brien Lifehouse is a cancer treatment center and hospital in Australia. It has partnered with Samsung Australia and the virtual reality studio Start VR to bring Samsung Gear VR headsets to patients waiting to receive chemotherapy.
The idea? Instead of worrying about their health and the hospital experience, patients may become absorbed in VR. Not only does this provide some relief to patients who want to escape the daily realities of a cancer diagnosis and the hospital setting, it does so without additional prescriptions or medical treatments.
At Chris O'Brien Lifehouse, patients may choose content from the Gear VR store or Start VR's catalog. Possible experiences include petting koalas, exotic travel destinations, boat rides and skydiving.
While this hospital is likely one of the first to use VR as "distraction therapy" to soothe and calm exhausted patients, VR is already being put to work in many other healthcare settings. For example, an MRI physicist at King's College Hospital in London has developed a VR app to help kids prepare for an MRI in a safe, low-anxiety way.
