ABSTRACT
BACKGROUND: A phase II randomised trial was conducted to evaluate the tolerability and activity of weekly or 3-weekly docetaxel in patients with metastatic breast cancer. PATIENTS AND METHODS: Eighty-three patients with histologically proven metastatic breast cancer were randomised to receive either docetaxel 40 mg/m2 weekly for 6 consecutive weeks followed by 2 weeks without treatment (n = 41), or docetaxel 100 mg/m2 on day 1 every 3 weeks (n = 42). RESULTS: The incidence of all grade 3-4 adverse events was higher in the 3-weekly group than in the weekly group (96 versus 44), and the number of patients with grade 3-4 adverse events was also greater in the 3-weekly group (31 versus 20). Analysis of individual adverse events tended to favour the weekly regimen. Intent-to-treat overall response rate was 34% and 33% in the weekly and 3-weekly groups, respectively. Median time to progression was 5.7 and 5.3 months after weekly and 3-weekly docetaxel, respectively, and median time to treatment failure was 4.1 and 4.9 months, respectively. CONCLUSION: Weekly docetaxel is an active regimen in metastatic breast cancer with comparable efficacy to 3 weekly docetaxel. Although both schedules were well tolerated, weekly docetaxel appears to have a more favourable toxicity profile.

A multicentre phase II trial was undertaken to evaluate the activity and toxicity of docetaxel plus cisplatin as first-line chemotherapy in patients with urothelial cancer. Thirty-eight patients with locally advanced or metastatic transitional-cell carcinoma of the bladder, renal pelvis or ureter received the combination of docetaxel 75 mg m(-2) and cisplatin 75 mg m(-2) on day 1 and repeated every 21 days, to a maximum of six cycles. The median delivered dose-intensity was 98% (range 79-102%) of the planned dose for both drugs. There were seven complete responses and 15 partial responses, for and overall response rate of 58% (95% CI, 41-74%). Responses were even seen in three patients with hepatic metastases. The median time to progression was 6.9 months, and the median overall survival was 10.4 months. Two patients who achieved CR status remain free of disease at 4 and 3 years respectively. Grade 3-4 granulocytopenia occurred in 27 patients, resulting in five episodes of febrile neutropenia. There was one toxic death in a patient with grade 4 granulocytopenia who developed acute abdomen. Grade 3-4 thrombocytopenia was rare (one patient). Other grade 3-4 toxicities observed were anaemia (three patients), vomiting (five patients), diarrhoea (four patients), peripheral neuropathy (two patients) and non-neutropenic infections (seven patients). Docetaxel plus cisplatin is an effective and well-tolerated regimen for the treatment of advanced urothelial cancer, and warrants further investigation.

PURPOSE: To determine the activity and evaluate the toxicity of uracil and tegafur in a 4:1 molar concentration (UFT) plus low-dose leucovorin administered concomitantly with pelvic irradiation in patients with unresectable or recurrent rectal cancer. METHODS AND MATERIALS: Thirty-five patients (22 with primary unresectable tumors and 13 with locally recurrent tumors) were enrolled in the trial. Thirty-five patients were evaluable for toxicity and 32 of these were evaluable for clinical response. Patients received 300 mg/m2/day UFT and 30 mg/day leucovorin on days 8-35 concomitantly with pelvic radiotherapy, to a total dose of 45 Gy. RESULTS: Eight of the 35 (23%) patients developed Grade 3 diarrhea and were treated with radiotherapy alone after this event. Of the 22 patients with unresectable primary tumors, 17 underwent surgery, and resection was feasible in 15 cases (88%). Of the 32 patients evaluable for clinical response, 4 (13%) had a complete clinical response (CR) and 22 (69%) a partial response (PR). A complete pathologic response was observed in 3 cases (18%) and, a PR in 11 cases (65%). CONCLUSION: The response rates achieved with this schedule seem comparable to those obtained with 5-FU and radiotherapy. These results warrant further evaluation of this combination in patients with unresectable or locally advanced tumors.
