“My path to medical school hasn’t been direct or easy. But I’m determined to forge a better future and be the advocate for others that I wish I’d had.”

Kim Czepiga was packing for a family trip to Italy in 2005 when she learned there had been an abnormal finding on her recent mammogram.

Czepiga had been diagnosed with Stage 0 breast cancer in 1999. For the past five years, she’d gotten a high-risk mammogram and MRI every six months. Her most recent mammogram was supposed to be the last — according to treatment protocols, after five years with no recurrence, she would be declared cancer-free.

The day before Czepiga, her husband and her four children left for their trip, she went in for scans. When she returned, she learned that the scans showed she had stage IV metastatic cancer that had spread to all four lobes of her lungs. Even with chemotherapy, her prognosis was 16 months.

“At that moment, my heart dropped out of my chest. I thought, oh my God, I have four kids,” Czepiga says. At the time, her oldest child was 17 and the youngest was 7. “That’s not much time.”

Czepiga started treatment, which was chemotherapy combined with the drug Herceptin®. “Back then, you went to a big ward for chemo, and you would sit next to other people getting treatment,” Kim says. “It was through that experience that I learned how many people die.”

That was when Czepiga decided to start researching clinical trials. As a healthcare administrator, she knew the most cutting-edge treatments were in clinical trials.

“I immediately quit my job — we went back to cutting coupons, went on a budget — and I spent 40 hours a week researching online with my medical dictionary next to me. That’s how I first learned about UW Medicine and the Cancer Vaccine Institute.”

"When I go in for treatment and tell people I’m alive and healthy 20 years after a Stage IV diagnosis, I’m a unicorn. But when I go back to CVI, I’m in a room full of unicorns, men and women who are 20 years out from a terminal diagnosis."

An innovative approach to cancer treatment

The Cancer Vaccine Institute (CVI) at UW Medicine is a community of scientists, doctors, nurses, patients and philanthropists focused on a single goal — to end cancer globally.

The CVI’s unique approach to cancer treatment and prevention rests on a discovery that Nora Disis, MD, made early in her career as a researcher — that cancer patients were having an immune response to cancer cells. UW Medicine founded the Cancer Vaccine Institute, with Disis as its Director, to explore the possibility that the immune system can be trained to identify cancer cells as dangerous — and destroy them.

More than two decades later, Disis’s initial hypothesis has been proven right. The CVI has developed a suite of vaccines, many currently in clinical trials, which are designed to safely treat and prevent the most common and deadly cancers. Ten years of patient data has been collected for breast and ovarian vaccines, showing promising results. A lung cancer vaccine, also in clinical trials, is not far behind. Vaccines for colon, bladder and prostate cancer are on deck and moving toward clinical testing. Together, these six types of cancer are responsible for more than 50% of cancer diagnoses and deaths.

Czepiga’s story demonstrates the transformational impact cancer vaccines have on care. While she was researching clinical trials and learning about the CVI, she was also struggling with the side effects of her cancer treatments.

“I could barely get up the stairs or walk from my car to the sidelines of my kid’s soccer game,” she says. “I thought maybe, with a vaccine, I could get some of my quality of life back.”

Czepiga was also encouraged by two women in her online breast cancer support group. One of those women is now, like Czepiga, a member of the CVI’s patient advisory council, a group of past trial participants who advise the CVI’s leadership on education and engagement. They had both had positive experiences with the CVI and Disis.

“I sent in my paperwork and my bloodwork and crossed my fingers,” says Czepiga. “And then I got the call that I was in the trial.”

How do you make a vaccine for cancer?

When you get a vaccine for measles, chickenpox or the flu, you’re training your immune system to attack the bacteria or virus that causes the disease. Once the immune system knows how to respond to the measles virus, or this year’s strain of the flu virus, it can stop the infection from spreading before it causes symptoms.

The CVI’s cancer vaccines work in much the same way. They train the immune system to recognize and attack specific types of cancer cells — for example, for HER2+ breast cancer — destroying cancer cells and tumors. These vaccines often work in conjunction with a patient’s treatment with the hope of reducing the need for painful, difficult treatments like chemotherapy. And, because the immune system remembers its response to these cancer cells, the CVI’s vaccines can create immunologic memory, preventing the cancer from recurring.

A future step for the CVI is giving these safe, effective vaccines to patients at high risk for cancer before they are diagnosed. For patients with a family history or genetic predisposition to cancer, these vaccines could stop the development of cancerous tumors before they start.

"Cancer vaccines are inexpensive to manufacture and extremely effective,” says Disis. “If we can move these vaccines through clinical trials and available to patients, we can have an enormous impact on health and well-being, here and around the world."


Nora Disis, MD, talks about the progress the CVI has made — and the promise of a cancer-free future.

Making a revolutionary treatment available to everyone

Czepiga finished her chemotherapy, as required by the CVI trial, and took the first of many trips from Connecticut to Seattle to get a vaccine.

“I was so excited to be in Seattle. I was full of hope that the vaccine would work for me,” she says.

The vaccine did work. While Czepiga still needs regular scans and treatments, she’s healthy and thriving 20 years after joining that CVI clinical trial. And she’s far from the only person to benefit from cancer vaccines.

“When I go in for treatment and tell people I’m alive and healthy 20 years after a Stage IV diagnosis, I’m a unicorn,” she says. “But when I go back to CVI, I’m in a room full of unicorns, men and women who are 20 years out from a terminal diagnosis.”

Czepiga has lived life to the fullest over those 20 years. She exercises every day, is a devoted grandmother of two, and was there for her eldest daughter’s wedding — all of which seemed impossible when she first applied to a trial at CVI.

That’s the power, and the promise, of cancer vaccines.

“We are very encouraged by the results of our trials after following patients for 10-plus years. We can see that our vaccines are producing a strong enough immune response to kill cancer,” says Disis. “Our goal now is to partner with a company capable of taking our vaccines through Phase 3 clinical trials and ultimately submitting it for FDA approval. That’s how we make these vaccines available to more people.”

The importance of developing new cancer vaccines — and of making existing vaccines widely available — becomes clearer by the day.

Nearly 40% of Americans will be diagnosed with cancer during their lifetime. Globally, cancer deaths are expected to increase dramatically by 2050 as people live longer and access gaps grow. And, in the United States, cancer rates in people under 50 are rising, particularly rates of breast and colon cancer — two cancers for which the CVI has developed vaccines.

Philanthropy has already had a major impact on the CVI. Gifts from the Cancer Vaccine Coalition, Rivkin Center for Ovarian Cancer Research, Andy Hill Cancer Research Endowment and others have funded important steps in vaccine development, from testing new delivery methods for ovarian cancer vaccines to funding an expanded Phase II clinical trial for breast cancer vaccines. But more funding is always needed to help get vaccines to more patients, faster.

“Cancer vaccines are inexpensive to manufacture and extremely effective,” says Disis. “If we can move these vaccines through clinical trials and available to patients, we can have an enormous impact on health and well-being, here and around the world.”

"In my lifetime, I want nothing more than to see this treatment available to everyone. I’ll do everything in my power to make that happen."

The future is cancer-free

Since joining the clinical trial two decades ago, Czepiga has remained an active supporter of the CVI. She previously served on the CVI Development Council and is currently a member of the patient council as well as a donor.

“I am 110% convinced that the CVI’s work is the first wave of the future of cancer treatment,” says Czepiga. “I want my daughters to have access to these vaccines.”

Due to their family history of cancer — in addition to Czepiga’s breast cancer, other family members have had ovarian, colon and liver cancer — Czepiga’s children are aggressively screened for many different types of cancer. “They’re getting all these MRIs and tumor marker tests,” she says, “and I just keep thinking, what if they could get a vaccine instead?”

Twenty years after being told she had less than two years to live, Czepiga is alive, energetic and working to make sure everyone is able to access the advances that have given her so much.

“In my lifetime, I want nothing more than to see this treatment available to everyone,” says Czepiga. “I’ll do everything in my power to make that happen.”
