Recruitment & Eligibility

• Status: ot Recruiting
• Sex: All
• Target Recruitment: 95

Inclusion Criteria

- Persistent or locally relapsed and/or metastatic disease (in case of local disease, surgery may be technically feasible or not, but the clinical judgment must be that medical therapy is indicated)
- Pathology specimens available for centralized review
- Age = 18 years
- ECOG PS = 2
- One or more previous systemic treatments employing anthracyclines and ifosfamide (unless one or both are clinically contraindicated)
- Measurable disease, as defined by RECIST criteria
- A minimum of 3 weeks since any previous medical therapy
- Recovery from toxic effects of prior therapies to NCI CTC Grade 1 or lower
- Adequate haematological, renal and liver functions
- Ability and willingness to provide informed consent

Primary Outcome Measures

Name	Time	Method
Main Objective: Confirming the activity of the drug trabectedin as second/further line treatment in retroperitoneal leiomyosarcoma and well differentiated/dedifferentiated liposarcoma expressed in terms of slowing down tumour growth. <br><br>;Secondary Objective: To investigate the peculiar benefit provided by trabectedin in typical retroperitoneal sarcomas, in order to help multidisciplinary clinical decision-making;Primary end point(s): Proportion of responders to trabectedin by means of Growth Modulation Rate, that is the ratio between PFS under trabectedin (PFS) and time to progression after previous chemotherapy treatment (TTP1). The primary end point will be calculated in the overall sample;Timepoint(s) of evaluation of this end point: 6 years

Secondary Outcome Measures

Name	Time	Method
Timepoint(s) of evaluation of this end point: 6 years;Secondary end point(s): - Objective response (OR) in the overall sample<br>- Pathological tumour response in the two eligible histological types, in patients undergoing surgery after treatment<br>- PFS and OR in the two eligible histological types<br>- PFS in patients who undergo surgery after, or during, trabectedin treatment and those who do not<br>- Safety profile<br>- Efficacy of trabectedin in reducing cancer related pain
