BACKGROUND: Current regimens for treatment of distant metastases of soft tissues sarcomas result in response rates of about 25%. Therefore the search for active drugs remains a task for investigational groups. Taxoids offer a new class of cytostatic drugs. Docetaxel has been studied as a second line chemotherapy in advanced soft tissue sarcomas of the adult. PATIENTS AND METHODS: In a multi-center non-randomized phase II study docetaxel was administered at a dose of 100 mg/m2 in a 1-hour i.v. infusion q 3 weeks. RESULTS: Twenty-nine patients (pts), median age 52 yr, performance status WHO 0: 16 pts, WHO 1: 11 pts, WHO 2: 2 pts, were eligible. One patient had early death due to malignant disease, 1 patient died due to toxicity and progression, 1 pt refused after 1 course. Five partial responses (5/29 = 17%, C.I. 6%-36%) have been observed. Grade > or = 3 leucopenia occurred in 76% of patients and grade > or = 3 thrombopenia did not occur. Median nadir of neutrophils was 0.23 x 10(9)/l. Episodes of fever and documented infection have been observed in 10 and 5 pts respectively. Anaphylactoid type reactions occurred in 5 patients: ranging from flushing in 5 pts to cardiovascular symptoms in 1 pt. Sensory neurotoxicity was observed in 14 pts grade 1: 10 pts, grade 2: 3 pts, grade 3: 1 pt). Grade 1 motor neurotoxicity was experienced by 3 pts. Skin reactions (pruritus, erythema, urticaria, exfoliation grade 1: 11 pts, grade 2: 7 pts, grade 3: 1 pt, grade 4: 1 pt) in 20 pts, among them 9 patients with nail changes. Peripheral edema and fluid retention has been observed in 12 pts. CONCLUSION: Taxotere has activity in adult soft tissue sarcoma in second line, warranting studies on first line efficacy.
