Desmoid tumors: diagnostic and therapeutic considerations.

A literature review on desmoid tumors was carried out, which are tumors that affect soft tissues with a locally aggressive behavior and are unable to metastasize. Sporadic cases are located on the extremities and chest wall; hereditary cases have an intra-abdominal predilection, and those associated with pregnancy occur on the abdominal wall. Imaging techniques assess disease extension. Trucut biopsy is the study of choice for diagnosis. Mutations in the CTNNB1 or APC genes cause an abnormal accumulation of b-catenin within the cell. In this review, an emphasis is made on therapeutic strategies' evolution and change, and current tools for decision making are analyzed, as well as clinical outcomes. Radiation therapy can play a therapeutic or adjuvant role. Advances in the understanding of the disease have allowed establishing better targeted treatments with lower morbidity; however, there are still unanswered questions regarding the choice of the ideal candidate for surveillance and/or early treatment. Data related to quality of life are also presented, as well as the uncertainty generated by this diagnosis for both doctor and patient.
