The number of effective cytotoxic agents for the treatment of patients with metastatic adult type soft tissue sarcoma (STS) is limited, when patients have failed anthracyline-based chemotherapy. The aim of this trial was to evaluate the efficacy of gemcitabine in this setting.


Between August 2001 and March 2003 19 patients were eligible to enter. Gemcitabine was administered as a 30-minutes infusion at a dosage of 1 g/m2 on day 1, 8 and 15 every 4 weeks. All patients had progressive disease during (n = 12) or shortly after an anthracycline-based regimen (n = 3).


Four of 19 patients did not start study treatment because of fulminant progression. Fifteen patients with a median age 47 years (32-72) were assessable. All patients had received at least one prior treatment regimen (range, 1-6) for metastatic disease containing anthracyclines (n = 15) and ifosfamide (n = 11). To date, a total of 72+ cycles have been applied (median; 3, 1-28+). Seven patients (47%) had progressive disease after completion of two cycles at the first response assessment. One patient (6%) attained a partial remission, and 7 patients (47%) achieved disease stabilisations. One patient is still on treatment after more than 2.5 years. The calculated progression-free rate at 3 and 6 months was 46.7% (CI(95%), 21.4-71.9) and 13.3% (CI(95%), (0-30.5). 95% of the cycles have been applied without any dose modification or treatment delay.


Considering response and progression-free rate as the primary endpoints for phase II trials in pretreated STS, gemcitabine has moderate efficacy.
