PEREZ-CALVO, Javier et al. Neoadjuvant treatment with imatinib for a giant tumor of the rectal gastrointestinal stroma. rev. colomb. cir. [online]. 2018, vol.33, n.4, pp.428-432. ISSN 2011-7582.  https://doi.org/10.30944/20117582.90.

Less than 5% of gastrointestinal stromal tumors (GIST) are located at the rectum. When these tumors are locally advanced, neoadjuvant therapy with imatinib has shown good results, reducing its volume. We present the case of a patient with a giant rectal GIST tumor, who underwent neoadjuvant imatinib therapy, and posterior low anterior resection with coloanal anastomosis.

In rectal GIST tumors it is essential the multidisciplinary evaluation and treatment, in order to obtain the best possible results in this rare entity. After a good response to the treatment with imatinib, aggressive surgeries can be avoided, along with the associated morbidity that comes with it.
