Moreover, a post-marketing observational study in Japan assessed the safety and effectiveness of eribulin across various soft tissue sarcoma subtypes, including leiomyosarcoma, reinforcing its role in treatment despite the limited options available for these patients (ref: Kawai doi.org/10.1186/s12885-022-09527-y/). The findings across these studies underscore the need for continued research into combination therapies and the role of biomarkers like ctDNA in predicting treatment outcomes, as they may significantly influence clinical decision-making and patient management strategies.
