• Key mediator in Wnt signaling pathway • Wnt targets include c-Myc • Wnt also implicated in development of colorectal and other GI carcinomas
• Additional mutations in the pediatric population

Diagnosis
• CT • Preferred for intra-abdominal lesions

• Biopsy • Confirms the diagnosis
• Endoscopy • Suspected FAP

• Radiation Therapy • Primary usually given as 50 – 60 Gy over 5 – 7 weeks • Adjuvant indicated for R2 resection • Adjuvant not shown to be beneficial for R0/R1 resection • Neoadjuvant requires more studies

Intra-abdominal Desmoids
• Surgical Resection • FAP
• Often unresectable • High rate of recurrence after resection • Resection reserved for small, well-defined tumors with clear margins • However may shorten mesentery • Prevent Ileal Pouch Anal Anastomosis for Proctectomy resulting in Ileostomy

Surveillance
• History and Physical with appropriate imaging • Every 3 – 6 months • For 2 – 3 years • Then annually

Recurrence
• Estimated 16 – 39% recurrence rate despite R0 resection • Up to 50% recurrence within 5 years
• Recurrence risk likely linked to underlying biology rather than margins • No difference in survival between R0 and R1 resection • Aggressive resection to achieve R0 may not be beneficial • Resection or Chemotherapy ± Radiation Therapy are options

Conclusion
• Non-metastasizing, locally recurrent disease • Heterogeneous presentation
• Sporadic, Gardner Syndrome, Pregnancy-associated • Extremity, Abdominal Wall, Intra-abdominal
• R1 resection acceptable if avoiding undue morbidity • Recurrence likely related to underlying biology and less so margins • Trend toward less invasive approach such as observation
