The purpose of this study was to estimate the response rate, response duration, and survival of patients with advanced ovarian cancer treated with a 132-hr continuous infusion of high-dose calcium leucovorin in combination with five consecutive daily bolus doses of 5-fluorouracil (5-FU) and to correlate changes in CA-125 levels with clinical and radiologic assessment of disease progression. Forty-six heavily pretreated patients [median number of previous chemotherapy regimens, 2.5 (range 1-7)] with advanced ovarian cancer received 132-hr continuous infusions of calcium leucovorin (500 mg/m2/day) for 5 1/2 days, with daily bolus doses of 5-FU (370 mg/m2/day) for 5 days beginning 24 hr after initiation of the calcium leucovorin. Twenty-three patients had clinically measurable disease and 23 had evaluable disease; CA-125 levels were performed prior to each treatment course and after the final course of therapy. One of 42 patients had a partial response to combination chemotherapy (duration, 8.9 months); 16/42 had stable disease [median duration, 4.9 months (range, 2.4-9.0 months)]. Toxicity of combination therapy included mild myelosuppression and stomatitis, similar to previously reported toxicity profiles for the 5-FU and calcium leucovorin combinations. Sensitivity of CA-125 levels as a single indicator of disease progression was 55%. The combination of infusional high-dose calcium leucovorin and 5-FU has little activity in refractory ovarian cancer. CA-125 levels incorrectly predict clinical disease activity in about one-third of cases and should not be the sole criterion for determination of clinical response when evaluating chemotherapeutic efficacy in heavily pretreated patients.

Based on reports of substantial antitumor efficacy of the combination of mitoxantrone (DHAD), 5-fluorouracil (FU) and leucovorin (LV), a clinical trial was performed to attempt augmentation of the dose of DHAD with filgrastim support. The doses and schedules, all intravenous, were DHAD (total dose divided over days 1 and 2), level I, 16 mg/m2; II, 20 mg/m2; III, 24 mg/m2; IV, 32 mg/m2; and LV, 300 mg, followed by FU, 350 mg/m2, on days 1-3. Filgrastim was given at 5 micrograms/kg/day subcutaneously on days 4-13. The planned cycle length was 21 days. Three or 4 patients were to be entered at each dose level and the maximum tolerated dose (MTD) was defined as the dose immediately below that which resulted in 2 patients with dose-limiting toxicity (DLT) in cycle 1. Once an apparent MTD was identified, an additional 6 patients were to be entered. Twenty patients (pts) were entered: level I: 3 pts; II: 3 pts; III: 10 pts: IV: 4 pts. The major toxicity was found to be cumulative thrombocytopenia with platelet counts < or = 20,000/microL occurring after cycle 1 at all levels beyond level I and five pts (25%) were removed from treatment solely because of platelet toxicity. Additional serious toxicities included grade 4 stomatitis in one patient (level IV) and cardiac toxicity in 2 patients with prior doxorubicin exposure. Ten pts had measurable and 8 had evaluable disease, and in 17 pts assessed, 5 (29%) achieved an objective response. The response rates in this study are lower than reported in the literature for the combination of DHAD, 5FU, LV and this may be related to the fact that only 40% of the patients were removed from protocol treatment because of disease progression. On the basis of limited DHAD-dose augmentation, toxicities observed, and modest response rate, the filgrastim-supported DHAD, 5FU, LV regimen as utilized in this study cannot be recommended for further development for treatment of women with metastatic breast cancer.

The aim of the present study was to evaluate the clinical activity and side effects of a combination chemotherapy consisting of a five-day continuous infusion of fluorouracil and i.v. vinorelbine in metastatic previously treated breast cancer patients. The patient population was represented by 28 women with evaluable disease, previously subjected to chemotherapy, including anthracycline-containing regimens in 89% of patients. Treatment consisted of five-day infusion of 700 mg/m2/day of fluorouracil and vinorelbine, 20 mg/m2 i.v. bolus on day 1 and 6. In the absence of Grade > 3 leukopenia and stomatitis, cycles were repeated every three weeks, for a total of six cycles. Four complete and thirteen partial responses were documented, accounting for a response rate of 61% (95% CI: 40.5-78.5); the clinical efficacy was high even in patients unresponsive to prior anthracycline treatment. The median response duration calculated from the first drug injection was 8 months (range 4-11). Treatment was well tolerated, with 4% Grade 4 stomatitis and 20% Grade 3 leukopenia as the main toxic reactions. This drug combination is active in metastatic previously treated breast cancer patients, is devoid of severe side effects, and warrants further testing.

The aim of the study was to define a regular and tolerable dose of the epirubicin-docetaxel combination in first-line chemotherapy of patients with metastatic breast cancer. Sixty-five women with measurable and/or evaluable disease were treated with epirubicin escalated from 60 to 110 mg/m(2) according to 5 dose levels, in combination with a fixed dose of 75 mg/m(2) docetaxel, every 21 days for 6 cycles, without preventive use of hematopoietic growth factors or antibiotics. Forty-three women received adjuvant chemotherapy, consisting of anthracyline- or anthracenedione-based regimens in 39 cases (60%). Twenty-seven women were treated in the phase I study (3 at epirubicin 60 mg/m(2), and 6 at each subsequent dose level). Dose-limiting toxicity consisted of grade III asthenia and febrile neutropenia (epirubicin 75 mg/m(2)), grade IV thrombopenia and grade III asthenia (epirubicin 90 mg/m(2)), grade IV stomatitis and grade III diarrhea (epirubicin 100 mg/m(2)), and grade III diarrhea (epirubicin 110 mg/m(2)). In the phase II study, an additional 38 women were treated at epirubicin 90 mg/m(2) and epirubicin 100 mg/m(2). During the 349 cycles delivered, grade IV neutropenia occurred in 90%; febrile neutropenia requiring hospitalization occurred in 62 (17.8%) and lasted more than 3 days in 12 (3.4%). Nonhematologic toxicity was acceptable. Three left ventricular ejection fraction depressions occurred and normalized during follow-up. The overall response rate in the 62 evaluable women was 69.4% (range: 58--81%), with a median duration of 7.8 months. After 26 months of follow-up, the median time to progression was 9.1 months and median overall survival was 22.7 months. On the basis of efficacy and toxicity, the recommended dose of the combination is epirubicin 100 mg/m(2) plus docetaxel 75 mg/m(2).

Vinorelbine has proven to be effective in pretreated metastatic breast cancer patients. In particular, no cross-resistance with anthracyclines has been demonstrated. Protracted 5-fluorouracil infusion presents a better pharmacological profile than its bolus administration. The aim of this study was to investigate the efficacy and toxicity of the combination of these two antitumor drugs in patients with metastatic breast cancer who had been previously treated with anthracycline-containing regimens. From February 1998 to January 2000, 65 patients were enrolled into the study The most important inclusion criteria were as follows: Karnofsky 70-100, measurable or evaluable disease and normal renal, hepatic, bone marrow and cardiac function. Mean age was 48 years (range: 31-70). Fourteen of the 65 women had already received more than one chemotherapy line. Twenty-three patients had previously been treated with taxanes. Sites of involvement were the lungs in 50% of the patients, the liver in 37%, soft tissue in 72%, bone in 58% and other sites in 32%. Treatment consisted of vinorelbine 25 mg/m2 administered on days 1 and 6 every 21 days and 5-fluorouracil 700 mg/m2/day for 5 consecutive days. The total number of cycles was 340 (mean: five cycles). The treatment was well tolerated. Febrile neutropenia was observed in 4.6% of patients. Fourteen percent of patients experienced grade 3 or 4 neutropenia, and 3% experienced grade 3 thrombocytopenia. Grade 3 stomatitis was observed in 9.2% of patients, grade 3 neurologic toxicity was observed in 1.5%, and grade 3 cardiotoxicity in 4.6%. Grade 3 site reaction occurred in 3% of patients. Sixty patients were evaluated for response. One patient (1.7%) attained complete clinical response and 28 (46.7%) attained partial response. In 22 patients (36.6%) stable disease was documented and nine patients (15%) progressed while on treatment. Median time to progression was 24 weeks, median duration of response was 35 weeks and median overall survival was 41 weeks. Vinorelbine with 5-day infusion of 5-fluorouracil presented high therapeutic activity in breast cancer patients previously treated with anthracyclines, with acceptable toxicity.
