Uterine leiomyosarcomas and soft tissues are rare tumors with a poor prognosis when metastatic or locally advanced. They have an average chemosensitivity mainly to doxorubicin, ifosfamide, cisplatin, gemcitabine and trabectedin but response rates in combination in first line does not exceed 55% for uterine leiomyosarcomas and 35% for leiomyosarcomas of soft tissue.
