Gynecological sarcomas are rare, constituting 3-5% of uterine malignancies. Endometrial stromal sarcomas and some uterine leiomyosarcomas are characterized by estrogen receptor (ER) and progesterone receptor (PgR) expression with variable impact on their clinical behavior and potential response to systemic therapies. A variety of hormonal treatments have been tested, since they act as targeted treatment against ER and PgR and have a tolerable side effect profile, which allows them to be administered for prolonged periods. Their role has been studied more extensively in endometrial stromal sarcomas, as the majority of cases are ER/PgR positive, while recently, an emerging role for hormonal manipulation has been described in ER/PgR-positive uterine leiomyosarcomas. Owing to the rarity and heterogeneous nature of uterine sarcomas, current treatment recommendations are based on small retrospective studies and case reports. This review comprises a critical appraisal of the existing data regarding hormonal manipulation in uterine sarcomas and attempts to make recommendations for endocrine treatments in specific settings, as well as suggest targets/medications for future research.

Imatinib mesylate is considered the standard first-line systemic treatment for patients with chronic myeloid leukaemia (CML) and gastrointestinal stromal tumour (GIST) by targeting BCR-ABL and c-KIT tyrosine kinases, respectively. Indeed, imatinib has substantially changed the clinical management and improved the prognosis of both diseases. Treatment with imatinib is generally well tolerated, and the risk for severe adverse effects is low, generally occurring during the early phase of treatment and correlating with imatinib dose, phase of disease and patient's characteristics. This article summarises recent data on safety profile of imatinib for the treatment of CML and GIST, including long-term side effects. Prolonged treatment with imatinib in both diseases demonstrates excellent tolerability. There are few significant concerns and those that have emerged, like cardiotoxicity, have far turned out to be exaggerated.
