Rowan’s Story: Joy, Strength, and Genetic Breakthroughs

In late 2021, eight-year-old Rowan arrived at the emergency room weakened by weeks of unexplained illness. Due to Covid-related restrictions, his father and brother waited at home while his mother sat with him, unaware that their lives would change forever. After testing, doctors found a golf ball-sized tumor in Rowan’s cerebellum, blocking the natural flow of spinal fluid through his brain.

What followed was a whirlwind of surgeries, treatments, and countless hours in hospital rooms. Through six weeks of daily proton radiation therapy and nine cycles of chemotherapy, Rowan powered through every side effect. Even during his first chemo infusion, he sat calmly eating Doritos as if it were just another ordinary day. His younger brother stood by his side, ready to play whenever Rowan had the energy. They often played with Legos, which helped rebuild his fine motor skills.

Between treatments, Rowan looked for every opportunity for joy. He conquered a rock-climbing wall, soared through an aerial obstacle course, and proved his tenacity by completing the third grade on time despite spending much of the year in treatment. When his port was finally removed in November 2022, his family felt like a new chapter was beginning.

But in October 2023, a second tumor appeared – a high-grade glioma caused by his previous radiation treatment. This time, the treatment path was guided by genetic sequencing thanks to CURE’s investment in the Precision Medicine Program. Through this testing, doctors discovered that Rowan had Li Fraumeni Syndrome (LFS). Most people have a pair of proteins that keep cells from growing abnormally and becoming cancerous. Because of LFS, Rowan’s body doesn’t make enough of these proteins, and cells can divide uncontrolled and form tumors.

Without the genetic sequencing, Rowan would have undergone rounds of harsh infusion chemotherapy. Instead, armed with the knowledge of his LFS, doctors opted for a more targeted approach with oral chemotherapy that reduced his risk for additional tumors. The genetic testing also revealed that Rowan had inherited LFS from his mother, Charlan, leading to important, life-long, monitoring protocols for both of them.

Rowan & Jacob Today

Rowan is eleven years old and writing a new chapter of his story. He is in middle school, plays the trombone, and continues to choose joy every day. Regular MRIs every three months keep careful watch, allowing doctors to catch and treat any potential issues in the early, more treatable phase. Made possible by genetic sequencing, this proactive approach gives Rowan and his family the power of knowledge and early intervention.

“We won’t put their heads in the sand but rather face each day armed with understanding and hope.” his mother, Charlan, said. “For Rowan’s younger brother Jacob, genetic testing brought relief because it confirmed he doesn’t carry the LFS gene.”

Rowan’s story illustrates the power of precision medicine and genetic sequencing in childhood cancer care. It’s about a boy who loves his family and friends, being in school, and trying many kinds of games and activities – and how scientific advancement helps him continue doing all these things. Through genetic testing and a determination to find joy in every moment, Rowan and his family continue their journey – not just surviving but truly living.

It’s in the Genes

Ally has been through a lot in her eleven years. When she was two years old, she fell off a stool while playing with her brother. A large bruise appeared on her stomach almost immediately, and her parents took her to their local hospital. After blood work, they learned that Ally had B-cell acute lymphoblastic leukemia. “We were told that within days, she would have had uncontrollable bleeding without treatment,” said Ally’s mother, Amber. “Her body was working so hard to fight the cancer that her heart would have given out. It is hard to be glad for your child to fall, but that fall saved her life.”

Ally received her first dose of chemotherapy within 16 hours of diagnosis. Over the two years of treatment that followed, Ally struggled with almost every possible side effect. She suffered three life-threatening infections, temporarily lost the ability to walk, and struggled to rebuild her immune system after every round of chemo.

“We were given a bleak prospect of survival during her second fight with an infection,” shared Amber. “We prayed for a miracle and finally got one when her body started to respond to antibiotics.”

Her treatment finally ended on August 24, 2018, but her battle was far from over because her immune system did not recover as expected. Even years later, her doctors were concerned because she was still living with depleted immune function. In 2022, they decided to do genetic sequencing on Ally and her family to see if a disorder was causing her immune system deficiency. What the sequencing uncovered has lifelong implications for Ally and her family.

“My nephew was diagnosed with leukemia after Ally,” said Amber. “So I expected that if there was an inherited genetic trait linked to her cancer or her body’s response to treatment, it would be on my side. We found out that the opposite was true.”

Ally shares a genetic condition called Lynch syndrome with her father, Justin. This condition increases the risk of many kinds of cancer, including colon cancer, endometrial cancer, and other types. Knowing this will allow Justin and Ally to be monitored for early signs of cancer, giving treatment a greater chance of success. Ally sees a doctor with expertise in genetic conditions every year, and her parents are updated on new testing and protocols. Ally is doing great today. She is in her first year of middle school and enjoys competing in pageants. Her parents are grateful for her health and credit CURE’s investment in precision medicine as a big part of it.

“I have a friend who just went through breast cancer treatment, and her genetic testing cost $4,000 out of pocket,” Amber said. “The cost of repeated gene sequencing for us would have been staggering. But it didn’t cost us a dime because of CURE’s funding. We wouldn’t have known about the syndrome without it. With this knowledge, we can be prepared and should be able to detect any cancer in Ally or Justin early.”

We Finally Have Hope

young boy named Easton, a recipient of personalized cancer medicine

Easton has been fighting cancer for most of his twelve years. When he was 21 months old, he was constantly sick. His pediatrician noticed that his sickness was abnormal – he vomited more frequently in the mornings and while sitting in his car seat. A scan revealed a large tumor on Easton’s brain stem near the area that controls swallowing and nausea.

“The fact that Easton would get sick after being in his car seat made our pediatrician suspicious,” recalled his mother, Jill. “If the car seat hadn’t put pressure on the tumor, it might have taken longer to find.”

Easton had surgery to remove as much of the tumor as possible, followed by eight weeks of proton radiation in Jacksonville, Florida. His family was thrilled when a follow-up scan showed no presence of the tumor.

“We thought it was over,” said Jill. “We were told that if we had five years of clear scans, we wouldn’t have to worry about it again. Easton had four years of clear scans. But the cancer came back during the fifth year.”

Easton started treatment all over again in 2017 and experienced horrible side effects from the chemotherapy and radiation. Because the tumor grows around the area of the brain that controls swallowing, he has always had challenges eating. The awful mouth sores from his chemo caused him to be on a mostly liquid diet, and he had trouble maintaining weight.

In May 2022, Easton underwent a very risky surgery to try and remove the last part of the tumor. The surgery was unsuccessful. As he started recovering, Easton fell out of bed in the middle of the night. His parents rushed him to the emergency room, where doctors found that Easton’s brain was having a reaction to the glue that was used on his skull after surgery. He would need another risky brain surgery.

“This time, I felt like it was getting away from us and it was the beginning of the end,” said Jill. “He had been on some form of treatment for five years, and the tumor always found its way around it.”

But thanks to funding from CURE Childhood Cancer, Easton’s doctors have a new tool in their toolbox. CURE’s funds would pay for Easton’s tumor to be genetically mapped to see if his cancer involved any genetic mutations that could be targeted.

The genetic mapping revealed that a protein was feeding Easton’s tumor, causing it to grow. Doctors found an open clinical trial using a chemotherapy to inhibit this specific protein to prevent further tumor growth. Easton was immediately enrolled in the trial, and the results have been astounding. After four months, a scan showed that the inside of Easton’s tumor appeared to be dying. Three months later, the tumor is much smaller and is collapsing in on itself.

“The best news is that the tumor is dying. But also, he has no side effects. He can do the things a twelve-year-old should do while on this treatment,” shared Jill. “We’re still early in the process, but it has saved his life – at least at this point. I finally have hope for the first time in years. We are so encouraged and thankful to his doctors and to CURE for investing in precision medicine.”

Take the next step to support research that will help save kids with cancer… kids like Easton.

2023 Research Grants

CURE CHILDHOOD CANCER PROUDLY ANNOUNCES $5 MILLION IN RESEARCH GRANTS

Research has led to significant improvements in survival rates for many childhood cancers over the past few decades. For example, the five-year survival rate for all childhood cancers combined has increased from less than 60% in the 1970s to more than 80% today. However, there is still much work to be done, and continued research is crucial for further progress.

To that end, CURE is proud to announce that we are directing $5 million, the most CURE has ever funded in a single year, to research aimed at solving childhood cancers that remain so hard to cure!

In this year’s grant cycle, we were extremely pleased to receive more than 70 grant applications. Following a rigorous grant review process with a committee of researchers and scientists, CURE is funding 12 targeted projects at leading institutions across the country. CURE’s research priorities are two-fold. First, we prioritize research that will lead to more effective treatments for children within two to three years. We also prioritize research aimed at solving recurrent and hard-to-treat cancers for which no effective treatment exists.

This is the most significant grant cycle we’ve ever had for several reasons. For example:

MORE EFFECTIVE – All of the research studies we are funding aim to make more effective therapies that are better tolerated, with a special emphasis on relapsed and refractory disease.
LESS TOXICITY – Five of the research projects we are funding are specifically aimed at harnessing the immune system’s power to fight cancer instead of using today’s toxic chemotherapies.
FASTER DELIVERY – We are addressing both near-term work that is anticipated to enter clinical trials in the next 2-3 years and funding work that contributes to long-term cancer biology understanding, which will impact research for decades.
BREAKING BARRIERS – Crossing the blood-brain barrier to deliver chemotherapy drugs directly to a brain tumor is challenging. Two studies we are funding focus on better delivery of drugs to address this issue.
PINPOINTING PROBLEMS – We continue to prioritize precision medicine. With our funding, researchers are getting closer to knowing which drugs are most likely to be effective against some of the most difficult childhood cancers.

Because bright young physicians often leave pediatric research for more lucrative pursuits, we expanded our research funding to include three early investigator awards to get these scientists started.

Another way we work to support young doctors and ensure they are trained to care for children with cancer and advance research is to fund the fellowship training of three pediatric oncology fellows at Emory University’s School of Medicine: Dr. Toni Chanroo, Dr. Robert Lisac (Sam Robb Fellow), and Dr. Jason Stevenson (Connolly Family Fellow).

2022 Research Grants

CURE CHILDHOOD CANCER PROUDLY ANNOUNCES MORE THAN $4.7 MILLION IN RESEARCH GRANTS

Research is the key to ensuring children with cancer have the opportunity to thrive long beyond diagnosis. CURE’s research priorities are two-fold. First, we prioritize research that will lead to more effective treatments for children within two to three years. We also prioritize research aimed at solving recurrent and hard-to-treat cancers for which no effective treatment exists. Precision medicine, gene-based therapy, continues to be our highest priority, as we believe this approach to treatment shows extraordinary promise.

In response to CURE’s request for proposals, we received dozens of studies seeking funding. Expert oncologists and academic researchers reviewed and scored each proposal using the same process employed by the National Institutes of Health. Their scores and critiques guided CURE’s board, ensuring we invest funds in the most strategic and prudent fashion.

We are proud to share that our 2022 research grants are focused almost entirely on helping children facing the toughest diagnoses – high-grade brain tumors, aggressive leukemias and solid tumors, and metastatic disease. These 18 grants awarded to top scientists at leading pediatric cancer research institutions across the nation total more than $4.7 million, CURE’s highest disbursement in a single grant cycle in our 47 year history.

“We are so pleased and proud that CURE is providing such a high level of support to very promising research this year,” said Kristin Connor, CEO of CURE Childhood Cancer. “We are urgently focused on getting new treatments to those children with high-risk, difficult-to-treat cancers that currently lack effective treatments. Virtually all our grants this year are aimed at doing that, which gives me so much hope for these children.”

The grant includes funding for these difficult to treat cancers:

5 High-risk blood cancer studies (3 AML, 2 B-cell ALL)
7 High-grade brain tumor studies (3 DIPG, 1 high grade glioma, 3 medulloblastoma)
2 High-risk solid tumor studies (neuroblastoma and Ewing sarcoma)

In an effort to ensure the best and brightest young minds are trained to care for children with cancer and advance research, we also proudly announce our funding of the fellowship training of three pediatric oncology fellows at Emory University’s School of Medicine: Dr. Frank Chien, Dr. Robert Lisac (Sam Robb Fellow), and Dr. Sanyu Janardan (Connolly Family Fellow).

Advancing Science Together

As you read this, CURE’s Peer Review Committee is evaluating 44 research proposals from scientists at 27 institutions who are seeking funding. Based on their feedback, we will select the life-saving research that we fund in our next award, and you can have a direct impact on the process.

These proposals have the potential to significantly improve treatments for pediatric cancers where current options are not adequate and, if funded, to be in clinical testing or treatment phases within 2-3 years.

The committee is reviewing cutting-edge research and will score proposals the researchers hope will lead to better treatments for cancers that affect children. These proposals include new methods to fight the most common cancers like leukemia and lymphoma. They also seek to advance science that will impact children diagnosed with the hardest to treat brain tumors, sarcomas, and metastatic disease.

These proposals have come in from leading research institutions across the country.

Each submission is being reviewed by two committee members who have specific knowledge and interest in the cancer type of the proposal. In May, we will host a meeting during which every submission will be discussed by the entire committee. Members will have the opportunity to ask questions and vote to accept or change the overall score. These final scores will be ranked and presented to CURE’s Board of Directors on June 21, and final funding decisions will be made.

This is where you come in. Before the funding decisions are made in June, you can increase the amount of funding available for these projects by renewing your gift by May 31. Additionally, because of a $100,000 matching gift from a generous donor, your impact could be doubled. This is a chance for you to make a direct impact on the way we treat childhood cancer.

The Long Journey from Idea to Bedside

Dr. Michael Jensen of Seattle Children’s Hospital is one of the leading authorities on CAR T-cell therapy. He has been working on CAR T-cell therapy for many years, and his work is proving to be very beneficial for pediatric cancer patients. This type of therapy provides hope that someday children can receive far less-toxic medicines that lead to a cure.

Dr. Jensen started his career in the late 1990s at City of Hope National Medical Center in Los Angeles, where his research looked at the technology to take immune cells from a cancer patient and genetically modify them to recognize and attack cancer cells. This is something the patient’s natural immune system can’t do. His research was groundbreaking at that time, and his lab had to build everything from scratch.

“This was similar to creating the Apollo rocket and trying to land on the moon,” Dr. Jensen said. “We had to invent and create every step of the process and make sure the quality was sufficient. Once the first cells were infused, it was literally like landing on the moon and hoping that everything went right.”

It took over a decade of small trials to work out each and every kink, and obtaining funding for something so revolutionary was challenging. One source of consistent funding came from Lauren’s Run. From the beginning, Lauren’s parents were looking for groundbreaking research that would help children with cancer. After learning of Dr. Jensen’s research, they decided that it was exactly what they were looking for and made sure proceeds from the race supported his work.

His breakthrough came in 2014, when doctors using the patient’s own immune system through CAR T-cell therapy started seeing dramatic remissions in children with leukemia who were otherwise out of options.

“Without a functioning immune system, cancer would be much more common,” explained Dr. Jensen. “Think of cancer cells as a semi-truck on a freeway down a mountainside with the brakes broken, and the gas pedal stuck on full. On the way down, the cells acquire genetic programs and mutations and become uncontrolled. The human immune system is challenged because this isn’t a virus that came from outside the body. It doesn’t help that the cancer cells create deflector screens to fool the immune system into peaceful coexistence when we would like for the immune system to attack.”

CAR T-cell therapy takes the T-cells out of the body and supercharges them. The supercharged cells are then put back into the body as a surprise attack on the cancer cells, and the deflectors are not always effective in turning off the immune response. Ideally, within a week or two, the patient goes into remission. The cells then continue to move to all parts of the body, hunting and eliminating any remaining cancer cells. Over 90% of leukemia patients whose initial treatment didn’t work go into remission when given CAR T-cell therapy!

Leukemia was the first target, but the goal is to get CAR T-cell therapy to work against other childhood cancers. CAR T-cell therapy represents a major step toward a safer cure for children. It started as an idea in the mind of brilliant researchers years ago and is now a frontline treatment for many children. But it didn’t happen overnight. It was a long process, and Lauren’s Run was with them every step of the way.

Using our Immune Systems to Cure Cancer

By Chris Porter, MD
Pediatric Hematologist/Oncologist
Aflac Cancer & Blood Disorders Center of Children’s Healthcare of Atlanta

Researchers have learned a great deal about how the human immune system can function as physiologic superheroes – able to prevent and cure diseases, including cancer. Like particularly cunning comic book villains, some cancers devise intricate plans to weaken their superhero foes – think kryptonite to Superman. In our lab, we have been investigating how blood cancer cells evade the immune system and have discovered that the cancer cells use a molecular kryptonite, called Siglec15, to weaken the immune cells. Fortunately, there may be ways to shield our immune cells and new ways to strengthen them, which we are actively pursuing every day.

Cancers derived from blood cells, including leukemia and lymphoma, are the most common cancers in children. Thanks to research, cure rates are better than ever. But cancer remains the leading cause of illness-related death in children. Thus, there is a need for better therapies, and understanding how cancer cells behave is critical to developing better medicines.

Dr. Chris Porter

A couple of years ago, our lab found that leukemia cells depend on a protein called calcineurin to evade immune cells. In the cell, calcineurin helps control the expression of a number of other proteins. One of the proteins that calcineurin controls is a signaling molecule, IL-12. This molecule is a member of a family of signaling proteins called cytokines. Researchers have known for a long time that IL-12 very strongly stimulates immune cells to kill cancer cells. However, IL-12 has not been an effective therapy, in part because it can cause several side effects. To get around this problem, we are collaborating with scientists at Emory University and the Georgia Institute of Technology. Together we hope to develop a nanomedicine to deliver IL-12 exactly to where it needs to be, where immune cells interact with cancer cells. This will effectively give additional super-powers to help the immune cells eliminate the cancer cells.

In addition, we found that calcineurin controls the expression of Siglec15, a protein of which not much is known. Leukemia and lymphoma cells seem to make a lot of Siglec15, which we know can inhibit immune cells. In fact, children with leukemia have much higher levels of Siglec15 in their blood than healthy individuals. Now we are trying to understand how the leukemia and lymphoma cells make it and how it inhibits the immune cells. In addition, we are working with a drug company that makes a medicine that can block Siglec15, which could act as a forcefield for the immune cells.

Thus, with funding from CURE, we are making great strides in figuring out ways to strengthen and protect immune cells, which should let these superheroes destroy the villainous cancer cells.

2021 Research Grants

CURE CHILDHOOD CANCER PROUDLY ANNOUNCES MORE THAN $3 MILLION IN RESEARCH GRANTS

When CURE’s fiscal year began, we were squarely in the midst of the COVID-19 pandemic and couldn’t begin to predict how the year ahead would unfold. As circumstances became more dire for many families we serve, we quickly realized we needed to invest more funds in supporting our patients and families. At the same time, revenue was declining as the pandemic forced us to cancel events and hold others virtually. While we were confident that our priority needed to be helping families through these extraordinary times, we did not want to let up on research support. How would we be able to do it all, we wondered? Our community answered by giving generously to ensure critical research could move forward even in the pandemic.

Thanks to you, CURE is delighted to announce more than $3 million in research grants for the 2021 fiscal year!

Our research priorities are clear. First, we prioritize research that is likely to reach the bedside within five years. Second, we focus on research that will improve the outcomes for the 20% of children not surviving today’s methods of treatment. In furtherance of these goals, we continue to prioritize precision medicine and advancing the Aflac Precision Medicine Program at Children’s Healthcare of Atlanta.

Four years ago, our funding made the Aflac Precision Medicine Program a reality. The results in these four short years have been dramatic. Since its clinical introduction, genetic sequencing of tumors has provided actionable results in 78% of the patients – meaning that the information obtained through this sequencing impacted the treatment of 78% of the children in some way. What an extraordinary impact this sequencing makes. CURE’s investment of $1.8 million this year will allow the Aflac Precision Medicine Program to provide genetic sequencing for more children in addition to going deeper with the genetic testing – in other words, analyzing even more genes that may be contributing to tumor growth. CURE’s Precision Medicine grant will also enable research into racial and ethnic differences which may affect a child’s outcome. With our funds, scientists will explore and identify the immune factors that contribute to racial and ethnic differences in outcome. This exciting research will significantly impact children of all races diagnosed with cancer now and in the future.

We are again funding the training of three future pediatric oncologists through our Fellowship Program: Dr. Frank Chien, Dr. Robert Lisac (Sam Robb Fellow), and Dr. Sanyu Janardan (Connolly Family Fellow). By funding their training, we remove financial impediments and allow the fellows to focus on research and care of children fighting cancer as they begin their careers.

Your generosity allowed us to do even more than we believed possible. In addition to our precision medicine initiative and our investment in the fellows, CURE is also funding eight individual research projects aimed at solving difficult to cure cancers. Our 2020-2021 Pediatric Cancer Research Initiative includes the following studies:
