What second-line treatments are being reviewed for advanced soft tissue sarcoma after anthracycline?

moderate confidence  ·  Last reviewed May 27, 2026

Soft tissue sarcoma is a rare cancer with many different types. Once a patient has used anthracyclines like doxorubicin, doctors look for other drugs to control the disease. Clinical guidelines currently lack a single consistent recommendation for these second-line choices, meaning treatment often depends on the specific tumor type and the doctor's experience 1.

What the research says

Trabectedin is widely recognized as a standard second-line treatment for advanced soft tissue sarcoma following anthracycline failure 356. Studies show it offers a balance between tumor control and quality of life, with a manageable safety profile that allows patients to continue daily activities 56. Eribulin and pazopanib are also approved options in certain regions like Japan for patients who have previously received anthracyclines 1.

What to ask your doctor

  • Is trabectedin an appropriate second-line option for my specific soft tissue sarcoma subtype?
  • How does the safety profile of trabectedin compare to other second-line drugs like eribulin or pazopanib?
  • Are there clinical trials for newer agents, such as repotrectinib, that might be suitable for my tumor type?
  • What are the potential side effects I should expect from second-line chemotherapy or targeted therapy?
