Living with SFT: Surveillance and Survivorship

At a Glance

SFT requires lifelong surveillance because the tumor can recur 10 to 20 years after initial treatment. Patients follow a risk-adapted scan schedule, typically starting with frequent checks and moving to annual or biennial monitoring indefinitely to detect local recurrence or distant metastasis early.

Completing treatment for a Solitary Fibrous Tumor (SFT) is a major milestone, but it also marks the beginning of a lifelong journey of monitoring. Because SFT is known for its unpredictable behavior, “survivorship” in this context means staying vigilant even when you feel perfectly healthy ^[1]^[2].

The Reality of Late Recurrence

One of the most unique aspects of SFT is the risk of late recurrence ^[3]. While many cancers are considered “cured” if they don’t return within five years, SFT can reappear 10, 15, or even 20 years after the original tumor was removed ^[3]^[4].

Local Recurrence: The tumor may grow back in the same spot where it first appeared ^[5].
Distant Metastasis: SFT can spread to distant parts of the body, such as the lungs, liver, or bones ^[3]. For brain and spine tumors, these distant spreads have been documented as late as 9 to 13 years after diagnosis ^[3].

Because of this long-term risk, doctors often prefer the term No Evidence of Disease (NED) over “cured” ^[1]. NED means that current scans show no signs of the tumor, but it acknowledges that lifelong monitoring is necessary to catch any potential changes early ^[6]^[7].

Your Surveillance Schedule

While there is no single “one-size-fits-all” schedule, your follow-up plan will be tailored to your specific risk category (low, intermediate, or high) and the location of your tumor ^[8]^[9].

A typical surveillance plan might include:

The First 2 Years: Frequent scans (every 3 to 6 months) using MRI or CT to monitor for early recurrence ^[10]^[11].
Years 3 to 5: Scans may move to every 6 to 12 months if everything remains stable ^[12].
Year 10 and Beyond: Unlike many other conditions, monitoring for SFT should continue indefinitely. Even after a decade of “clean” scans, annual or biennial check-ups are often recommended ^[3]^[4].

Managing ‘Scanxiety’

The stress of waiting for follow-up scans and results is so common it has its own name: Scanxiety ^[13]^[14]. This anxiety often peaks in the days leading up to the scan and during the waiting period for results ^[15].

To manage scanxiety, consider these evidence-based strategies:

Minimize the Wait: Ask your doctor how quickly results will be available. Knowing you’ll hear back by a specific time can reduce the “limbo” period ^[16]^[17].
Focus on the Present: Techniques that focus on the “here and now,” rather than worrying about future outcomes, have been shown to help reduce anticipatory distress ^[18]^[19].
Seek Support: Having a friend or family member accompany you to appointments, or connecting with other SFT survivors, can provide vital emotional buffering ^[20].
Information as Power: Understanding your specific risk and why the scans are necessary can help you feel more in control of your health journey ^[17].

Common questions in this guide

Why do I need scans 10 years after SFT treatment?

SFT has a unique risk of late recurrence, meaning tumors can return 10, 15, or even 20 years after removal. Because of this long-term risk, doctors recommend indefinite monitoring to catch any potential regrowth or spread as early as possible.

What is the difference between 'No Evidence of Disease' (NED) and being 'cured'?

Doctors prefer 'No Evidence of Disease' (NED) because it accurately reflects that current scans show no tumor, while acknowledging the possibility of future recurrence. The term 'cured' implies the tumor will never return, which cannot be guaranteed with SFT due to its unpredictable nature.

How often will I need follow-up scans?

While plans vary based on your specific risk level, a typical schedule involves scans every 3 to 6 months for the first two years. If stable, scans may occur every 6 to 12 months for years 3 to 5, followed by annual or biennial check-ups indefinitely.

What is scanxiety and how can I manage it?

Scanxiety refers to the stress and anxiety patients feel leading up to medical scans and while waiting for results. Strategies to manage it include asking for a clear timeline on results, bringing a support person to appointments, and focusing on present-moment coping techniques.

Where does SFT typically recur?

SFT can recur locally at the original tumor site or spread to distant areas like the lungs, liver, or bones. Symptoms depend on the location but may include new lumps, persistent pain, or neurological changes like headaches or weakness.

Curated prompts to bring to your next appointment.

1.Based on my tumor's risk score or WHO grade, what is my specific imaging schedule for the next 2, 5, and 10 years?
2.Since late recurrence is a known risk for SFT, how will our surveillance plan change after I hit the 5-year and 10-year milestones?
3.Which imaging modality (MRI, CT, or PET/CT) is best for monitoring my specific tumor location and checking for distant spread?
4.Can you explain why we use the term 'No Evidence of Disease' (NED) instead of 'cured' for my situation?
5.How quickly can I expect to receive my scan results to help minimize my anxiety during the waiting period?
