(BPT) - In 2018, a vibrant young woman with a passion for theater and education set off on the quest of a lifetime: spending a month walking 500 miles on the Camino de Santiago pilgrimage from France to Spain. Christina K. was also at the beginning of a quest to learn more about a mysterious lump on her collarbone.
Months before her trip, one of Christina's colleagues insisted she get the lump on her collarbone looked at. While it was bothering her and even made some activities difficult, Christina was hesitant to have it checked because she didn't want to disrupt her long-planned European trip.
She relented, though, and an initial X-ray and ultrasound led her doctor to conclude it was a lipoma, a common, usually benign, fatty tumor that grows under the skin. With that diagnosis, Christina went on her trip, walking the 500-mile pilgrimage without giving the lipoma more thought.
When she returned, she prepared for surgery to remove the lipoma, taking time off from her rewarding job as a school drama teacher. But instead of hearing that the lump was indeed a lipoma that had been successfully removed, Christina was told by her doctor that he wasn't sure what type of tumor it was.
Sensing that something was seriously wrong, Christina decided to seek answers from various specialists. She finally received a diagnosis at a university-based medical center. But the answer turned out to be something she'd never heard of: a desmoid tumor. At the time, her surgeon spoke to her about the possibility of removing the tumor. However, he said that it would be a very invasive surgery. In addition to the tumor, he would need to remove her collarbone, surrounding muscle tissue, and part of her sternum. She was informed that the surgery could potentially affect her vocal cords, which were her lifeblood as a singer, actress and educator.
"I went into the specialist's office as someone who called herself healthy, who went yearly for my checkup, who was proactive in all the ways that I should have been - green smoothies in the morning, lots of exercise through yoga and dance. I was shocked and crushed when I got the diagnosis of a desmoid tumor."
What is a desmoid tumor?
Desmoid tumors are rare, locally aggressive soft tissue tumors that can form anywhere in the body where there is connective tissue.[1],[2],[3] Also called aggressive fibromatosis or desmoid fibromatosis, these tumors can cause significant pain, loss of physical function and mobility, disfigurement and a diminished quality of life.[1],[2],[4],[5],[6],[7],[8]
Managing desmoid tumors can prove to be challenging.[2],[5],[6] Unpredictable by nature and with a high likelihood of recurrence, desmoid tumors have a significant impact on people's lives.[6],[9],[10] Their invasive growth patterns exert pressure on nearby connective tissue and, in some instances, vital organs, potentially leading to life-threatening complications.[2],[5],[11]
Alternatives to surgery
Before making a decision about surgery, Christina met with her new oncologist and learned that surgery to remove desmoid tumors can be extremely complicated and often not successful.
"Desmoid tumors have these tendrils, like an octopus," Christina said. "You need to make sure you get every trace of them, because otherwise they can recur."
In fact, up to 77% of people with a desmoid tumor can experience recurrence following surgical removal.[12],[13]
With no U.S. Food and Drug Administration (FDA)-approved treatment for desmoid tumors available at the time, Christina's oncologist recommended several off-label treatments, including chemotherapy to try to shrink the tumor, which had grown to the size of a grapefruit.
The next few years were difficult for Christina, as she experienced severe reactions to the treatments that ranged from swelling and aching joints to nausea and her hair turning white. Unfortunately, none of the medicines slowed the tumor's growth, much less shrank it. During that time, the COVID-19 pandemic began, forcing Christina into isolation to protect her now immuno-compromised system and making it impossible to continue working as an educator.
A new treatment option
Just as it seemed there might not be any medical treatments left to try, Christina's doctor told her she could try an investigational treatment that was being studied specifically for desmoid tumors. In 2020, she began taking nirogacestat, now marketed by SpringWorks Therapeutics, Inc. under the brand name OGSIVEO®, and has been on that treatment ever since.
OGSIVEO (nirogacestat) is the first and only FDA-approved treatment for adults with progressing desmoid tumors who require systemic therapy.[14],[15] See Important Safety Information below.
Christina recently marked the six-year anniversary of her desmoid tumor diagnosis. She remembers hoping her tumor would stop growing and stabilize, exactly like her current situation.
Christina is still taking OGSIVEO and says that she has experienced a reduction in pain.
She has become a rare disease advocate through her Girl Meets Cancer Instagram and works as a program coordinator for the Cactus Cancer Society, which helps young adults facing cancer find support, connection and creative outlets.
Just as she confronted the challenge of a 500-mile walk from France to Spain, Christina views all these hurdles as part of her life adventure with a positive attitude that gets her through even the toughest days.
"I don't like the word 'journey,'" Christina said. "It's not. I try to say the word adventure. I'm ready to take this all on as a new adventure."

Important Safety Information
What is OGSIVEO?
OGSIVEO is a prescription medication used to treat adults with progressing desmoid tumors who require a medicine by mouth or injection (systemic therapy). It is not known if OGSIVEO is safe and effective in children.
Before taking OGSIVEO tell your healthcare provider about all of your medical conditions, including if you:
- Have liver problems.
- Are pregnant or plan to become pregnant. OGSIVEO can harm your unborn baby. Tell your healthcare provider if you become pregnant or think you may be pregnant during treatment.
