A phase II study of the effectiveness of docetaxel (Taxotere) in women with advanced breast cancer previously treated with polychemotherapy. Hellenic Cooperative Interhospital Group in Oncology.

PURPOSE: The aim was to study the effectiveness of docetaxel (Taxotere) in patients with advanced breast cancer treated previously with polychemotherapy. PATIENTS AND METHODS: Forty-nine patients received docetaxel (100 mg/m2; 1-h i.v. infusion) and corticosteroid premedication. Forty-one patients who had received previous anthracycline treatment were divided into anthracycline-refractory and anthracycline-resistant (early and late) groups. RESULTS: Of 45 evaluable patients, 66.7% had a partial response (PR) and 2.2% a complete response (CR), giving an overall response rate (ORR) of 68.9%. The ORR in anthracycline-refractory patients was 60% versus 82.6% in anthracycline-resistant patients; the difference was not significant. The ORR in early-resistance patients was 62.5% versus 93.4% in late-resistance patients (0.05 < P < 0.1). The median response duration and overall survival was 8 months (range, 4-23 + months) and 11.5 months (range, 4-31 + months), respectively, in 39 patients treated previously for metastatic disease. For 295 courses, grade 3/4 neutropenia developed in 28.6% of patients (12.5% of courses) and was febrile in 26.5% of patients (6.1% of courses), including one septic death. Hypersensitivity reactions (HSR) developed in 16.3% of patients, and fluid retention developed in 34.7% of patients (11.9% of courses). CONCLUSIONS: Docetaxel is an active second-line drug in advanced breast cancer. The time of relapse after cessation of anthracycline treatment may be a significant prognostic factor.

Docetaxel and granulocyte colony-stimulating factor in patients with advanced non-small-cell lung cancer previously treated with platinum-based chemotherapy: a multicenter phase II trial.

PURPOSE: To investigate the activity of docetaxel and granulocyte colony-stimulating factor support (G-CSF) in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with cisplatin. PATIENTS AND METHODS: A total of 60 patients with locoregional and metastatic NSCLC who had relapsed or progressed after first-line treatment with cisplatin-based regimens were enrolled into the trial. Docetaxel at 100 mg/m2 was given as a 1-h infusion with G-CSF (rhG-CSF given s.c. at 150 microg/m2) support from day 2 to day 8 every 3 weeks; all patients received premedication with corticosteroids. RESULTS: In all, 1 (1.6%) and 14 (23.3%) patients achieved a complete response (CR) and a partial response (PR), respectively, for an overall response rate of 25% (95% CI 14.0-35.9%); stable disease (SD) and progressive disease (PD) were documented in 18 (30%) and 27 (45%) patients, respectively. The median duration of response was 20 weeks and the median time to tumor progression was 28 weeks. The median overall survival was 32 weeks and the 1-year survival rate was 23%. A total of 263 courses were given at a median of 3 cycles/patient. Grade 3 and 4 neutropenia occurred in 11 (18%) and 14 (23%) patients, respectively, with 18 (30%) patients requiring hospitalization for neutropenic fever; 1 patient died of sepsis. Grade 2 peripheral neuropathy occurred in 9 patients (15%) and grade 3 asthenia, in 4 (7%). Other toxicities were mild. CONCLUSIONS: Docetaxel has considerable single-agent activity in patients with NSCLC who have relapsed or progressed after first-line chemotherapy with cisplatin-based regimens.
