Abstract:
20524 Background: The number of effective cytotoxic agents in treatment of advanced soft tissue sarcoma (STS) is limited when patients have failed anthracyclin and ifosfamide therapy. There are inconsistent data in phase I / II studies and retrospective analyses evaluating the efficiacy of gemcitabine (G, 900mg/m 2 , d1+8, q3w) or combination of gemcitabine and docetaxel (GD, G: 900mg/m 2 , d1+8, D: 100 mg/m 2 , d8, q3w). Methods: Between 2002 and 2006 we retrospectively analyzed 14 females and 6 males with heavily pretreated advanced soft tissue sarcoma (1–5 pretreatments) who were treated in our department (Charité Campus Virchow-Klinikum) with G (n=10) or GD (n=10) depending on their performance status. The following histology types were represented: leiomyosarcoma (10), liposarcoma (3), MPNST (3), synovial sarcoma (2), undifferentiated sarcoma (1), malignant large cell sarcoma (1). Results: A total of 99 cycles (range 1 to 15) were applied. Best response was partial remission (PR=20%, G: n=2, GD: n=2) and was achieved in four patients, among them three leiomyosarcoma and one MPNST. In six cases disease stabilization was achieved for up to 15 month (SD=30%, G: n=2, GD: n=4). Four patients had progressive disease after 2–3 cycles of gemcitabine based therapy (PD=20%, G: n=0, GD: n=4). In another six cases only day one of the first cycle (G alone) was administered because of serious problems due to pretreatment and poor performance status (e.g. prolonged thrombopenia and neutropenia Grade IV, gemcitabine-induced vasculitis, gastrointestinal bleeding due to tumor localization, pneumonia, rapid tumor progression). Conclusions: Gemcitabine-based therapy for heavily pretreated STS patients in our retrospective analysis has a significant overall response rate. In patients considered unfit for GD combination, single agent G treatment remains an option with moderate effiacy. No significant financial relationships to disclose.
