Continuing Education Activity

This activity reviews the evaluation, diagnosis, treatment, and latest advances in the field of leiomyosarcoma. It will discuss the existing literature and present the most recent evidence regarding treatment options available for patients diagnosed with soft-tissue sarcoma/leiomyosarcoma. It will also review the ongoing phase I-II trials and medications currently under evaluation to treat soft-tissue sarcoma/leiomyosarcoma. This activity will also highlight the interprofessional team’s role in managing leiomyosarcoma to optimize patient outcomes.


  • Identify the etiology of leiomyosarcoma.
  • Outline the management options available for leiomyosarcoma.
  • Summarize the latest molecules and clinical trials exploring treatment options for all soft-tissue sarcoma, including leiomyosarcoma.
  • Explain interprofessional team strategies for improving care coordination and communication to advance leiomyosarcoma and improve outcomes.

Here is the conclusion:
Conclusion of the study: The review of current literature led to the conclusion that we still have no reliable method to distinguish leiomyomas and leiomyosarcomas preoperatively. The studies in this field have, in most cases, retrospective design and the number of cases seems to be insufficient to achieve conclusive results. The rarity of malignant myometrial lesions is an obvious reason that explains such a situation.
However, on the horizon, we can identify new game-changing options that have the potential to revolutionize our practice in cases of myometrial lesions.
On one hand, there are many ambitious researchers introducing novel multi-parametric diagnostic scales, having promising performances in differentiating such lesions.
On the other hand, the recent advancement of machine learning and artificial intelligence constitute promising novel tools that give hope that we can solve this problem completely. Nowadays, the biggest challenge for researchers and clinicians is organizing multicenter databases that include numerous cases of both LM and LMS, and using them for the development and validation of these novel tools.
