Finding Hope in Her Genes

Rebecca Cook poses with her family on the last day of her latest round of chemotherapy treatments — July 21, 2021. Her cancer is currently in remission.

The Right Team at the Right Time

A DCI breast cancer care team joins forces with a genetics counselor to treat mother with high-risk genetic syndrome; prompting testing, then preventative screening for her kids.

Living a good life at age 35, Rebecca Cook thought she had more time before she needed to start thinking about screening for breast cancer. After all, she was a young mom of four kids who successfully managed to breastfeed for the past seven years, including a set of twins. (Breastfeeding, she had heard, is believed to lower breast cancer risk.)

And she thought time was on her side. (Cook hadn’t yet reached age 40, the recommended age to start screening women of average risk.)

But in February of 2020, as news reports began to swirl about the emergence in the U.S. of a potentially deadly virus, COVID-19, Cook found herself facing her own health crisis — a diagnosis of stage 3 inflammatory breast cancer.

She described the next few months on chemotherapy — 16 rounds of infusions at a clinic close to home in Norfolk, Virginia — as a whirlwind. Due to pandemic-safety rules, she was forced to attend her treatments in isolation — without the comfort of family or friends by her side.

Genetic Testing

Her doctors then suggested genetic testing, which revealed a rare, inherited, genetic disorder — Li Fraumeni Syndrome. The condition, identified by mutations in the TP53 gene, had predisposed her to cancer — not only the breast cancer she already had, but perhaps additional cancers down the road.

Cook said she felt "the deep and dark void of depression looming."

With the new diagnosis of Li Fraumeni Syndrome and with her cancer showing little sign of improvement, she requested a referral for more specialized care at Duke Cancer Institute.

"When I first arrived at Duke, I had that feeling that something was different," shared Cook. "It was a feeling that started to illuminate my dark path."

From her first appointment, she felt like she'd gained a fresh start with a care team that included breast surgical oncologist Lisa Tolnitch, MD, breast medical oncologist Michael Spiritos, MD, and radiation oncologist Diandra Ayala-Peacock, MD, as well as genetic counselor Elizabeth Wignall, MS, CGC, with the Duke Supportive Care & Survivorship Center’s Clinical Cancer Genetics program.

First, she'd undergo a double mastectomy. Unfortunately, the pathology results from her surgery showed that cancer was still present.

“The news is not what I wanted to hear, but I knew that I could put all my faith in their care,” said Cook, who then began a regimen of 14 more cycles of chemotherapy and intensive radiation at Duke Women's Cancer Care Raleigh.

When she walked into the initial appointment with genetic counselor Wignall, she was preoccupied. She wondered, "What could I have done differently?"

Wignall helped her to stop dwelling on the past and shift her focus to the future.

Because LFS is associated with a high lifetime risk for cancer — including, most commonly, soft tissue sarcomas, bone cancers (osteosarcomas), premenopausal breast cancers, colon cancer, gastric cancer, adrenal cortical tumors, and brain tumors — she advised Cook about the various types and timing of preventative scans she should undergo in order to detect any new cancers at the earliest stage possible. (More than one type of cancer may occur in the same person.)

In addition, knowing that there was a 50% chance her children shared her LFS diagnosis (and on Wignall's recommendation), Cook had her children tested for LFS. The tests came back positive for two of her four children. Next, Wignall worked with a team at Duke Children’s to get those children scheduled for preventative cancer scans — testing that will continue on a regular basis for the foreseeable future.

Taking action for herself and for her children gave Cook hope.

"Working with Elizabeth helped me to embrace that LFS is now part of my life story, NOT the defining moment of it," she shared. “While my heart may break that I passed on this gene to my kids, Duke provides a great genetics team to give us hope, as we walk this journey. Elizabeth's guidance has empowered me to educate my children that LFS is not something to be feared.They can carry on a 'normal' life. Their life just means more frequent scans, and being very aware of their bodies and any changes."

Rebecca Cook has all the love and support of her family

Cook completed the latest round of chemo treatments in July and was soon after declared "in remission." Over Labor Day weekend, she was able to participate and cross the finish line of her first half marathon.

“As much as I strive to keep the cancer away, keeping my mental health strong in this journey has been just as important. Running, counseling, medication, a healthy diet and medical providers that value mental health all help me do that,” she said.

Quit at Duke

James Davis, MD, was a third-year medical student when he realized he wanted to help people beat tobacco addiction. On his first night working in the hospital, he was called to the emergency room to see a patient he had previously admitted to the inpatient unit for chronic obstructive pulmonary disease. “I walked in, and her face had turned black with ash,” Davis said. “At first, I had no idea what had happened.” Then he realized that she had lit a cigarette while using high-flow oxygen, and it had exploded.Davis had gotten to know this patient, spending an hour conducting her history and physical. “She struck me as someone who was bright and capable. She was educated, had a career, and a family who loved her. But her tobacco addiction was so strong that she risked doing something dangerous to smoke a cigarette,” he said. “That experience was a wake-up call that it doesn’t matter how smart, well-adjusted, or successful you are. Addiction is an innate biological vulnerability, and it can impact anyone.”Today, he leads one of the largest smoking cessation programs in the United States: Quit at Duke. This team of 12 specially trained providers helps more than 6,000 people each year.In 014, Steven Patierno, PhD, deputy director of Duke Cancer Institute (DCI) recruited Davis to Duke to start a smoking cessation program for cancer patients. The team has since expanded it to serve all patients at Duke University Health System. “Drs. Steve Patierno, Mike Kastan, Cheyenne Corbett and others at DCI have provided the support necessary to turn this into a world-class smoking cessation program.” Davis said.Today, with the health dangers of cigarettes undisputed, most people who smoke have tried many times to quit but can’t. “They need more than a patch and a pep talk,” said Davis, associate professor of medicine. Cancer patients who smoke are often fighting for their lives. “If we’re going to ask them to quit smoking during one of the most the stressful periods of their lives, we better give them some highly effective tools,” he said.“Dr. Davis is very excited about what he does, and that is infectious,” said Quit at Duke program manager Jillian Dirkes, MSW, LCSW. “He always has energy and excitement to say, ‘Let’s find a new way to do this.’ That energy passes along to the rest of the team.”
