Desmoid fibromatosis: is the current picture changing?

Desmoid fibromatosis is a locally aggressive tumor with an unpredictable clinical course. Surgery was once the mainstay of treatment, but the treatment protocol has been constantly evolving and currently active surveillance is the front-line approach. There have been significant insights into the molecular biology with the addition of mutational analysis of Lay abstract Desmoid fibromatosis is an aggressive local tumor with continuously changing treatment paradigms. It requires MRI with biopsy for diagnosis and follow-up. Usually the tumor responds to a ‘wait and watch’ approach in most patients with either stable disease or regression on follow-up; a surgical plan is made only after multidisciplinary discussion, as surgery does not provide additional benefit in most patients. After a period of wait and watch, if there is disease progression, patients can be kept on medical management such as chemotherapy. Currently we have novel drugs for medical management like tyrosine kinase inhibitors, which result in disease stabilization in a majority of patients. In order to reduce the morbidity of treatment, it is essential for the patient to be on continuous follow-up and for clinicians to be updated with the continuously changing management of this disease.
