Locally Advanced or Metastatic Unresectable Liposarcoma After Anthracycline-Based Therapy

This protocol addresses patients with locally advanced, metastatic, or clinically unresectable liposarcoma — a stage at which surgical cure is not possible and systemic treatment is given with palliative intent.

Anthracycline-based chemotherapy — doxorubicin-based regimens — is the established first-line standard for this presentation. Escalation to a subsequent line of treatment is indicated when this therapy fails to achieve or sustain partial response or stable disease, or when tumour progression occurs on or after treatment.

Second- and further-line treatment relies on histology-driven chemotherapy, with agents that have demonstrated specific activity in liposarcoma — including options evaluated in randomised controlled trials for this histology. The complete evidence-based regimen selection is detailed in the structured protocol.

  • Trabectedin is an option in advanced STS in second and further lines of treatment. It has proved effective in LMS and liposarcoma [I, B; ESMO-MCBS v1.1 score: 2].
