Between June, 1983 and December, 1984, 142 patients with metastatic breast cancer were enrolled in this controlled, multicentre trial. The patients were given cyclophosphamide (600 mg/m2) plus 5-fluorouracil (750 mg/m2) and either adriamycin (45 mg/m2) (CAF) or mitoxantrone (13 mg/m2) (CNF). All drugs were administered intravenously on the same day every 21 days. An objective response was obtained in 28 of the 66 assessable patients (42.8%) in the CAF group (with 9 complete responses) and in 30 of the 71 assessable patients (42.2%) in the CNF group (with 6 complete responses). At the moment, the median duration of response is 37+ weeks with CAF and 34+ weeks with CNF (n.s.). It is still too early to evaluate the duration of survival. The major toxicity was bone-marrow suppression which required delayed administration or dose reduction in 40-45% of the patients. Nausea and vomiting were of comparable frequency in both groups, but they appeared to be less severe with CNF. Alopecia was less frequent and less pronounced in the CNF group. Moderate and clinically non-significant reduction of left ventricular ejection fraction was observed at cardiac ultrasonography or scintigraphy in 6 (10%) CAF patients and 2 (3%) CNF patients. None of the patients developed heart failure. Our results show similar response rates and toxicity with CAF and CNF. However, the mitoxantrone-containing treatment had a slight advantage as regards alopecia and the severity of nausea and vomiting.

Three hundred thirty-one women with metastatic breast cancer were randomized to receive combination chemotherapy with either cyclophosphamide, Novantrone (mitoxantrone; Lederle Laboratories, Wayne, NJ), and fluorouracil (CNF) or cyclophosphamide, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and fluorouracil (CAF). Patients could not have had prior chemotherapy, although adjuvant chemotherapy was acceptable. Initial doses were 500 mg/m2 of cyclophosphamide and 500 mg/m2 of fluorouracil with either 10 mg/m2 of mitoxantrone or 50 mg/m2 of doxorubicin, administered intravenously (IV) on day 1 and repeated every 3 weeks. There were no statistically significant differences in pretreatment or prior therapy characteristics between the groups. For patients assigned to the CNF and CAF groups, respectively, 25 (18%) were premenopausal, 39 (40%) were estrogen receptor (ER) negative, 39 (38%) had a disease-free interval less than 1 year, and 24 (26%) had received prior adjuvant chemotherapy. All patients were compared for response rate, duration of response, time to progression or death, time to treatment failure (TTF), and survival. None of these parameters were statistically significant favoring one regimen over the other. The response rate (complete [CR] and partial response [PR]) was 29% for the CNF group (95% confidence interval of 22% to 37%) and 37% for the CAF group (95% confidence interval of 29% to 45%). The median response duration and TTF were 171 days and 125 days for the CNF group and 254 days and 147 days for the CAF group, respectively. The median survival times for the CNF group and the CAF group were 377 and 385 days, respectively. The major dose-limiting toxicity for both regimens was leukopenia, manifested as granulocytopenia. The incidence of stomatitis/mucositis was 10% in the CNF group and 19% in the CAF group. Alopecia occurred in 49% of CNF patients (severely for 4%) and in 86% of CAF patients (severely for 39%). Nausea/vomiting occurred in 80% of CNF patients and in 81% of CAF patients; the degree of severity was also comparable. There was significantly less cardiotoxicity observed in the CNF group compared with the CAF group. Although CNF is somewhat less effective in overall response rate, survival curves are identical. CNF can be offered to patients who reject anthracycline-containing regimens because of fear of alopecia.

One hundred patients with metastatic breast cancer were randomly selected to receive combined chemotherapy treatment with adriamycin (50 mg/m2) or mitoxantrone (12 mg/m2) associated with 5-fluorouracil (600 mg/m2) and cyclophosphamide (600 mg/m2) administered intravenously every 21 days with a maximum of ten cycles. All patients included in this study were under 75 years of age and had ECOG performance status of less than 4. They had not been treated previously with chemotherapy for metastatic disease. Patients treated with adjuvant chemotherapy, which could not have included anthracyclines, had to have relapsed at least 12 months after the completion of therapy. There were no statistically significant differences in pretreatment characteristics or metastatic disease location between the two groups. Ninety-four patients were assessable for response. No differences were observed in response rate or in survival between the groups. The response rate (complete response (CR) and partial response (PR)) was 68% (13% CR and 55% PR for CAF; 0% CR and 68% PR for CNF). Median survival for all patients was 19 months (18 months with CAF and 19 months with CNF). All patients were assessable for toxicity. There were no differences in gastrointestinal and cardiac toxicity. More grade I-II hematologic toxicity episodes (p < 0.001) and treatment delays (p = 0.05) due to leucopenia were observed with the CNF group, and more grade III alopecia (p < 0.001) was observed with the CAF group. Patients received further therapeutic manoeuvres after finishing the study with a sequential treatment consisting of hormonal therapy and chemotherapy with mitomycin (M) -vinblastine (Vbl) (M 10 mg/m2 day 1, Vbl 5 mg/m2 days 1, 15 and 29; maximum 5 cycles). This chemotherapy treatment was received by 32 patients, with a response rate of 34% and grade III-IV hematologic toxicity of 37%. Treatment with CNF can be considered a good alternative to CAF for first-line treatment of metastatic breast cancer. M-Vbl treatment is useful as second-line treatment in patients with prior adriamycin exposure.

PMID:A phase III randomized trial of cyclophosphamide, mitoxantrone, and 5-fluorouracil (CNF) versus cyclophosphamide, adriamycin, and 5-fluorouracil (CAF) in patients with metastatic breast cancer. 774 56

A multicentric randomized study was conducted to compare the CNF regimen (cyclophosphamide at 600 mg/m2/iv, mitoxantrone at 10 mg/m2/iv, 5-fluorouracil at 600 mg/m2/iv) with the CMF regimen (methotrexate at 40 mg/m2/iv instead of mitoxantrone) administered every 3 weeks to previously untreated locally advanced or metastatic breast cancer patients. In 119 patients evaluable for therapeutic response, complete plus partial response rate was 44% for CNF and 29% for CMF (p>0.05; 95% C.I.: CNF=32%-56%, CMF=18%-40%). No statistically significant difference regarding time to progression, over survival or response to second-line chemotherapy with Epidoxorubicin was observed between the two regimens. Both regimens were well tolerated, but the percent of alopecia and leucopenia was significantly higher in the CNF patient group (31% versus 5% and 18% versus 0%, respectively; p<0.01). In conclusion, CNF was demonstrated to be slightly more toxic but more effective as compared to CMF (global response: 44% versus 29%, respectively). These findings should be taken into consideration when planning future studies of adjuvant chemotherapy.
