Chemotherapy (Gemcitabine, Docetaxel Plus Gemcitabine, Doxorubicin, or Trabectedin) in Inoperable, Locally Advanced, Recurrent, or Metastatic Uterine Leiomyosarcoma: A Clinical Practice Guideline

Questions: Does chemotherapy—that is, gemcitabine, gemcitabine plus docetaxel, doxorubicin, or trabectedin—improve clinical outcomes in women with inoperable, locally advanced, recurrent, or metastatic uterine leiomyosarcoma (lms)? Is there a difference in the tumour response rate to chemotherapy between recurrent pelvic disease and extrapelvic metastases in the target patients? Methods: This guideline was developed by Cancer Care Ontario’s Program in Evidence-Based Care, the Sarcoma Disease Site Group (dsg), and the Gynecologic Cancer dsg. The core methodology was the systematic review. The medline and embase databases (2004 to June 2011), the Cochrane Library, main guideline Web sites, and relevant annual meeting abstracts (2005–2010) were searched. Internal and external reviews were conducted, with final approval by the dsgs and the Program in Evidence-Based Care. Clinical Practice Guideline: Based on currently available evidence from the medical literature (four single-arm phase ii studies, one arm of a randomized controlled trial, and one abstract), doxorubicin alone, gemcitabine alone, or gemcitabine plus docetaxel may be treatment options in first- or second-line therapy (or both) for women with inoperable, locally advanced, recurrent, or metastatic uterine lms. Hematologic toxicity is common and should be monitored, and granulocyte colony–stimulating factor should be considered when gemcitabine plus docetaxel is used. Other toxicities, such as neurotoxicity, pulmonary toxicity, and cardiovascular toxicity should be monitored. No recommendation is made for or against the use of trabectedin in the targeted patients. No data were available concerning differences in response in recurrent pelvic disease or extrapelvic metastases, or concerning quality of life.
