What are the best treatments for Familial Adenomatous Polyposis?

The primary treatment for Familial Adenomatous Polyposis (FAP) is prophylactic surgical intervention to remove the colon and rectum, as the condition carries a near 100% lifetime risk of developing colorectal cancer without intervention. Treatment is highly personalized, focusing on the timing of surgery based on polyp burden and genetic mutation, often supplemented by endoscopic surveillance and chemoprevention.

What are the current surgical standards for Familial Adenomatous Polyposis?

Because the hallmark of Familial Adenomatous Polyposis is the development of hundreds to thousands of colorectal adenomas, surgery is the definitive management strategy. The two most common procedures include total proctocolectomy with ileal pouch-anal anastomosis (IPAA) or a total colectomy with ileorectal anastomosis (IRA). The choice between these depends on the severity of rectal polyposis and the patient’s specific genetic profile. At DiseaseMaps.org, 147 members have shared their experiences, highlighting how these surgical choices impact long-term quality of life.

Which medications are used to manage Familial Adenomatous Polyposis?

While surgery remains the cornerstone of care, pharmacological agents are used to manage polyp growth and mitigate risks. Common approaches include:

• Non-steroidal anti-inflammatory drugs (NSAIDs): Specifically celecoxib (Celebrex) or sulindac, which have been shown in clinical trials to reduce the number and size of polyps in the rectum or ileal pouch.


• Chemoprevention: Often used as an adjunct to delay the need for surgery or to manage residual polyps post-operatively.

Which specialists should be on the care team?

Managing Familial Adenomatous Polyposis requires a multidisciplinary approach to monitor both the gastrointestinal tract and extra-intestinal manifestations like desmoid tumors or thyroid abnormalities. Your care team should ideally include:

• A colorectal surgeon specializing in hereditary syndromes.


• A gastroenterologist with expertise in high-risk endoscopic surveillance.


• A clinical geneticist for family counseling and testing.


• A dietitian to manage nutritional needs post-colectomy.

Are there emerging treatments for Familial Adenomatous Polyposis?

Research is actively investigating novel therapies, including targeted chemoprevention and gene-editing technologies. Clinical trials are currently exploring whether specific pathways, such as the mTOR pathway, can be modulated to prevent polyp progression in patients with Familial Adenomatous Polyposis.
