    Notes: Abstract Purpose: To determine the maximum tolerated dose (MTD) and the dose-limiting toxicity (DLT) of weekly administration of docetaxel for three consecutive weeks every 4 weeks in patients with advanced solid tumors. Patients and methods: A total of 26 patients with malignant tumors refractory to conventional treatment were enrolled in this phase I study; their median age was 62 years. Of the 26 patients, 16 (62%) had previously received more than one chemotherapy regimen and 17 (65%) had previously received taxanes in a 3-week schedule. Docetaxel was administered after appropriate premedication at escalating doses (starting dose 30 mg/m2) as a 1-h i.v. infusion for three consecutive weeks in cycles of 4 weeks. Results: A total of 68 chemotherapy cycles were administered with a median of three cycles per patient (range one to six). The DLT was reached at 45 mg/m2 per week and the dose-limiting events were grade 4 neutropenia, febrile neutropenia, and treatment delay due to incomplete hematologic recovery. The MTD was defined at a dose of 42 mg/m2/week. Grade 3/4 neutropenia occurred in seven patients (27%) (10% of cycles), and four patients (15%) developed febrile neutropenia. There were no deaths due to sepsis. Grade 2 peripheral neurotoxicity was observed in two patients (8%), grade 2 and 3 fatigue in 14 (54%), grade 2 edema in seven (27%), mild allergic reactions in two (8%) and lacrimation in three (12%). One (4%) complete response and eight (35%) partial responses (overall response rate 39%) were observed in 23 evaluable patients. Stable disease and progressive disease were observed in six patients (26%) and eight patients (35%), respectively. All responses were observed in patients with metastatic breast cancer, one of whom had progressed on paclitaxel-based and two of whom had progressed on docetaxel-based chemotherapy. Conclusions: The weekly administration of docetaxel for three consecutive weeks every 28 days is a feasible schedule with a favorable toxicity profile, and can be given on an outpatient basis. Moreover, this schedule of docetaxel administration seems to have an enhanced efficacy, especially in patients with advanced breast cancer who have failed front-line taxane-based chemotherapy.

    Notes: Abstract Purpose: The activity of the docetaxel–gemcitabine combination in women with disease progression after initial chemotherapy for metastatic breast cancer (MBC) was investigated in a multicenter phase II study. Patients and methods: Fifty-two patients with metastatic breast cancer who had disease relapse or progression after completion of an anthracycline-based front-line regimen were treated with gemcitabine 900 mg/m2 on day 1 and day 8 and docetaxel 100 mg/m2 on day 8. G-CSF 150 µcg/m2/d s.c. was given from day 9 to day 16 and the treatment was repeated every three weeks. The patients' median age was 57 years and the performance status (WHO) was 0 for 26, 1 for 20 and 2 for 6 patients. The treatment was second-line for 27 (52%) and ≥ third-line for 25 (48%) patients. All patients were evaluable for response and toxicity. Results: Complete response occurred in seven (14%) patients and partial response in 21 (40%) for an overall response rate of 54% (95% confidence interval (95% CI): 40%–67%). Fifteen (29%) patients had stable disease and nine (17%) progressive disease. Of 25 patients previously treated with taxanes, 11 (44%) responded (1 CR, 10 PR). Interestingly, in four patients with disease progression while receiving docetaxel or paclitaxel monotherapy, the docetaxel + gemcitabine combination achieved partial responses. Responses were observed at all metastatic sites (local disease 62%, lymph nodes 58%, skin 44%, lung 47% and liver 36%) with a median duration of response of 3.6 months (range 1–16) and a median time to disease progression of eight months (range 2–18.5). Grade 3 neutropenia developed in 10 (19%) and grade 4 in five (10%) patients. Neutropenia was associated with infection in four patients without toxic deaths. Grade 3 thrombocytopenia developed in nine (17%) patients and grade 4 in two (4%). Non-hematologic toxicity was usually mild. Conclusion: The docetaxel–gemcitabine combination is an active and well tolerated salvage treatment in patients with MBC. Previous treatment with taxanes does not preclude a good clinical response to this regimen.

    Notes: Abstract Purpose: To determine the maximum tolerable dose (MTD) and the dose-limiting toxicity (DLT) of docetaxel (D) in combination with epirubicin (Epi) in patients with advanced breast cancer. Patients and methods: Forty-seven chemotherapy-naïve metastatic breast cancer patients aged 〈75 years with PS (WHO) 0–2 and adequate bone marrow, renal, liver and cardiac function, were enrolled in the study. Epi was given as a five-min bolus i.v. infusion on day 1 (d1) in escalated doses with increments of 10 mg/m2; D was given in a one-hour infusion after appropriate premedication on either day 1 or on day 2 in escalated doses with increments of 10 mg/m2. The patients' median age was 60 years, 42 (89%) had a PS (WHO) 0–1, 16 (34%) were premenopausal and 25 (53%) had visceral disease. Results: When the two drugs were given on the same day, the MTD1 was reached at the doses of Epi 60 mg/m2 and D 80 mg/m2; administration of G-CSF could not result in a dose intensification. When the drugs were given on two consecutive days, the MTD2 was reached at the doses of Epi 80 mg/m2 (d1) and D 90 mg/m2 (d2). The dose-limiting events were febrile neutropenia and grade 4 neutropenia, which developed in 30 (64%) patients during the study; among 227 delivered cycles grade 3–4 neutropenia occurred in 64 (28%) cycles but only 22 (10%) of them were complicated by fever. There were no septic deaths. Grade 1–2 neurosensory toxicity occurred in nine (19%) patients, mild edema in eight (17%) and allergic reactions in five (11%). Four (9%) patients presented a greater than 10% decrease of LVEF and treatment discontinuation was required in two of them; none of the patients developed congestive heart failure. Nevertheless, one patient suddenly died 10 days after treatment initiation of myocardial ischemia, and this death is considered treatment-related. Five (14.7%) complete and thirteen (38.2%) partial responses (ORR: 53.9%; 95% confidence interval: 36.1%–69.7%) were observed in 34 evaluable patients. Ten (29.4%) and six (17.6%) patients had stable and progressive disease, respectively. The median duration of response and time to tumor progression were five and seven months, respectively. The median survival has not yet been reached. Conclusions: The combination of epirubicin and docetaxel is a feasible and well tolerated regimen, but the MTD depends on the administration schedule of the drugs.

    Notes: Abstract Purpose:In a previous phase I trial we evaluated the toxicity anddetermined the maximum tolerated doses of the docetaxel (D)–epirubicin(Epi) combination. We conducted a multicenter phase II study to evaluate theefficacy and tolerability of this regimen as front-line treatment in womenwith advanced breast cancer (ABC). Patients and methods:Fifty-four women with ABC stage IIIB (4patients) or IV (50 patients) received front-line treatment with Epi 70mg/m2 on day 1 and D 90 mg/m2 on day 2. The median agewas 55 years, performance status (WHO) was 0–1 in 49 patients andvisceral disease was present in 45 (83%). Results:All patients were evaluable for toxicity and 50 forresponse. In an intent-to-treat analysis complete remission was observed in5(9%) patients, partial remission in 31 (57%) (overall responserate 66%, 95% confidence interval: 54%–79%),stable disease in 9 (17%) and disease progression in 9 (17%).After a median follow-up of 11.5 months, the median duration of responses was8 months, the median time to disease progression 11.5 months and the mediansurvival has not yet been reached. The probability of one-year survival was65%. Three hundred six cycles of treatment were administered (median6 cycles per patient). Grade 3 and 4 neutropenia was observed in 8(15%) and 31 (57%) patients, respectively, and febrileneutropenia in 19 (35%). Prophylactic rh-G-CSF was used in 45(83%) patients or 226 (74%) cycles. Other hematologic ornon-hematologic toxicities were usually mild. In five (9%) patients theleft ventricular ejection fraction (LVEF) was decreased by more than10% with the treatment. Two patients died during the treatment ofrespiratory failure without associated neutropenia. Conclusions:The combination of docetaxel–epirubicin is aneffective and well tolerated front-line treatment in patients with ABC.
