Background: Intra-abdominal fibromatosis (IAF) in the context of familial adenomatosis polyposis (FAP) is associated with significant morbidity and high recurrence rates after surgical resection. Non-surgical treatments are therefore advocated. This study explored outcomes in patients with IAF not associated with FAP who underwent surgical resection.
Methods: Data were analysed from a prospectively collected database at a sarcoma tertiary referral centre.
Results: From 2001 to 2011, 15 patients without FAP underwent primary curative surgical resection of IAF. Their median (range) age was 42 (19-64) years. Median tumour size was 18 (8.5-25) cm and weight 1306 (236-2228) g. Complete macroscopic clearance was obtained in all patients. There were no deaths in hospital or within 30 days and only one patient developed a major complication. Median follow-up was 40 (6-119) months. During follow-up two patients developed a recurrence after a disease-free interval of 12 and 16 months.
Conclusion: In contrast to FAP-associated IAF, non-FAP-associated IAF has a very low recurrence rate after surgical resection. Surgical resection is therefore advocated as first-line treatment in patients with non-FAP-associated IAF when resection can be performed with low morbidity.
