Pituitary carcinoma: A case report and discussion of potential value of combined use of Ga-68 DOTATATE and F-18 FDG PET/CT scan to better choose therapy.

Background: Pituitary carcinoma is extremely rare and carries a very poor prognosis. In most cases, apparently indolent tumors become malignant; however, there are no satisfactory biomarkers for predicting tumor behavior. Thus, scientific advances in the search for new biological markers, diagnostic methods, and therapies are needed to improve the prognosis of these patients.
