Anthracycline-Based Regimen Excels in FIGO-1 Uterine Leiomyosarcoma
Patients with uterine leiomyosarcomas treated with anthracycline-based regimens experienced longer disease-free survival compared to patients treated with gemcitabine and docetaxel, according to a retrospective analysis reported at CTOS 2018.
Roberta Sanfilippo, MD, of Fondazione IRCCS Istituto Nazionale Tumori, Milan, Italy, and her colleagues reviewed all patients with FIGO stage I uterine leiomyosarcomas at two Italian centers who underwent hysterectomy with or without oophorectomy and were then treated with adjuvant chemotherapy with anthracycline-based or gemcitabine-based regimens.
Of 145 patients, 97 were treated with an anthracycline-based regimen and 48 with gemcitabine and docetaxel. The median number of cycles of anthracycline-based therapy patients received was 4 (range 2-6) and the median number of cycles with gemcitabine and docetaxel was 5 (range 3-7). Disease-free survival was 31 months in patients treated with anthracycline-based chemotherapy and 19 months in patients treated with gemcitabine and docetaxel.
These results suggest that future trials to assess the efficacy of adjuvant chemotherapy in uterine leiomyosarcoma should incorporate anthracyclines, the investigators maintain.
