The purpose of this study was to determine whether methotrexate, vinblastine, doxorubicin, and cisplatin, each individually active in metastatic breast cancer (MBC), could, in combination, produce an overall response rate, median survival, and long-term survival sufficiently promising to merit its consideration for phase III trials in MBC and as induction therapy prior to autologous bone marrow transplant. From July 1986 through February 1990, 30 patients with stage IV, measurable breast carcinoma received M-VAC: methotrexate--30 mg/m2 days 1, 15, 22; vinblastine--3 mg/m2 days 2, 15, 22; doxorubicin--30 mg/m2 day 2; cisplatin--70 mg/m2 day 2. Cycles were repeated at 4-week intervals for up to six courses. Median age was 53 years (range 34-64 years). Prior treatment included adjuvant cyclophosphamide, methotrexate, and 5-Fluorouracil in 12 patients, radiotherapy in 13 patients, and hormonal therapy in 14 patients. Eleven patients were ER (+) at the time of initial diagnosis. Five patients had disease restricted to bone and/or nodes; the other 25 had visceral-dominant sites of metastases, with or without bone involvement, or evidence of rapid, inflammatory chest wall relapse. Twenty-nine of 30 patients were evaluable for toxicity and response; all were evaluable for survival. The major overall response rate was 83%, with a 21% complete remission rate. The chief toxicity was bone marrow suppression, with grade 4 granulocytopenia in 20 patients, grade 3 in 7 patients, and grade 3 and 4 thrombocytopenia in 5 patients. Grade 3 stomatitis occurred in 9 patients. Renal insufficiency was clinically insignificant, and neurotoxicity mild, with 7 patients sustaining grade 1 or 2 paresthesias. Median time to progression was 9 months and median survival 19 months (range, 5-84+ months) with 4 patients still alive at least 45+ months or more from the start of treatment and 2 presently free of progressive disease. Although highly toxic, M-VAC produces a response rate and survival duration in visceral-dominant MBC competitive with, if not superior to, conventional regimens such as CAF (Cytoxan, doxorubicin, 5-fluorouracil); it therefore merits further investigation in conjunction with hematopoietic growth factors and as cytoreductive therapy prior to autologous bone marrow transplantation.

A phase II study to test the toxicity and the efficacy of a weekly combination of Mitoxantrone, 5-Fluorouracil and L-Leucovorin (MFL) was carried out in 43 patients with metastatic breast cancer. Chemotherapy consisted of mitoxantrone 4 mg/m2, 5-fluorouracil 375 mg/m2, and L-leucovorin 100 mg/m2 on day 1, weekly. Patient characteristics were: median age 53 years (range 36-65); estrogen receptor (ER) status was known in 26 patients and of these 15 (57.7%) patients were ER-positive and 11 (42.3%) ER-negative. Of the 43 patients, 25 (58.1%) and 18 (41.9%) patients had received prior adjuvant chemotherapy and prior adjuvant endocrine treatment, respectively. MFL was administered to 22 (51.1%) patients as first line chemotherapy for advanced disease, while 21 (48.9%) patients had received 1 to 2 cytotoxic regimens for metastatic disease. The dominant sites of metastases were: soft tissue in 11 (25.5%) patients, bone in 8 (18.6%) patients and viscera in 24 (55.9%). All patients were assessable for toxicity: only 8 patients experienced WHO grade 3 leukopenia. Thrombocytopenia, diarrhea, stomatitis, and nausea/vomiting were negligible. Anemia and alopecia were not observed. Thirty-nine patients were assessable for response: overall response rate was 28.2% (complete response 7.7% and partial response 20.5%). Median duration of response was 12 months (range 6-34). Patients with no prior anthracyclines had a 42.1% response rate compared to 15% in patients who had received anthracyclines. Median overall survival of the 43 patients was 6 months (range 1-34). Weekly MFL is a well-tolerated and a moderately effective regimen for the treatment of metastatic breast cancer.

Standard combination chemotherapy for metastatic breast cancer produces response rates between 30-60% with limited impact on survival. We undertook a phase II trial to determine the activity of 5 fluorouracil (5FU) and folinic acid (FA) in patients with measurable metastatic or recurrent breast cancer who had received no prior chemotherapy. Patients meeting the eligibility criteria received 5FU 370 mg/m2/day and FA 200 mg/m2/day for 5 days repeated every 28 days, toxicity allowing. Response defined by standard criteria was assessed every 8 weeks and toxicity according to WHO criteria was determined on every course. Thirty-three patients were entered on trial. Thirty-two patients were evaluable for response and 33 for toxicity. The dose limiting toxicity was stomatitis with 7/32, 19/32, and 5/32 patients experiencing grade 1, 2, and 3 toxicity. Grades 1 and 2 diarrhea occurred in 17/32 and 11/32 patients respectively. Myelosuppression was not significant. Two complete and 11 partial responses were observed. The overall response rate was 41% (95% CI, 24-58%). Responses were seen in soft tissue and visceral sites. Patients who had received adjuvant chemotherapy more than 6 months prior to receiving 5FU and FA responded also. Six of 29 patients receiving standard combination chemotherapy as second line treatment responded subsequently. We concluded: 1) 5FU and FA is an active combination in the treatment of breast cancer warranting further evaluation in combination with other drugs; 2) the dose-limiting toxicity of stomatitis is tolerable; 3) patients receiving 5FU and FA as first line therapy can respond to conventional combination chemotherapy as second line treatment.

The purpose of this prospective clinical trial was an attempt to find an effective and relatively non-toxic schedule for patients with metastatic breast cancer who decline to receive aggressive cytotoxic chemotherapy. A total of 36 patients with disseminated breast cancer were treated with mitoxantrone 8 mg/m2 intravenously (i.v.) day 1, folinic acid 400 mg/m2 in a 2-h i.v. infusion with 5-fluorouracil 500 mg/m2 as an i.v. bolus 1 h later, days 1 and 8 at 3-week intervals plus prednisone 20 mg/m2 orally daily with diminishing doses over several weeks. Objective regressions were observed in 24/36 (67%) patients, 9 being complete (25%). Responses were seen at all disease sites, mainly pleural/lung, bone and liver. The median duration of response was 8 months (range 4-25+) and the median survival 12 months (range 3-26+). Myelosuppression, mainly leucopenia and thrombocytopenia, was the major toxicity but without complications. Other toxicities included mild or moderate nausea and/or vomiting (50%), stomatitis (33%) and diarrhoea (11%). Alopecia was minimal. No cases of cardiotoxicity were detected. The substantial response rate obtained with this relatively well tolerated regimen against advanced breast cancer warrants its assessment in a larger number of patients.

A comparative, randomized trial was conducted to determine the efficacy of oral UFT (Tegafur and Uracil) versus 5-fluorouracil (5-FU) in combination with cyclophosphamide and doxorubicin in patients with metastatic breast cancer. Of 62 evaluable patients, 31 received UFT (350 mg/m2/day orally x 14 days), doxorubicin (50 mg/m2 intravenously [I.V.] day 1) and cyclophosphamide (500 mg/m2 I.V. day 1). The other 31 patients received 5-FU (500 mg/m2 I.V. days 1 and 8), doxorubicin (50 mg/m2 I.V. day 1), and cyclophosphamide (500 mg/m2 I.V. day 1). Regimens were repeated for a total of six cycles. The two groups were comparable in terms of age, gender, performance status, menopausal status, and number and sites of metastases. No statistical difference in overall response rates was seen (UFT arm, 48.4% vs. 5-FU arm, 35 %; p = 0.30). Median response duration was 16 weeks (range, 4-30) for both arms. The toxicity profile (alopecia, anemia, leukopenia, thrombocytopenia, diarrhea) was similar in both groups and both regimens were well tolerated. Anemia and stomatitis were significantly more common in the 5-FU arm (p = 0.02). Thus, oral UFT has response rates and duration of response that are comparable to 5-FU in a combination regimen for advanced breast cancer.

9-Amino-20(S)-camptothecin (9-AC) is an analog of camptothecin with limited water solubility which has shown significant preclinical activity in a variety of human solid tumor xenografts. A Phase I trial using a soluble formulation of 9-AC, given as a 72-hour continuous infusion, has been completed. Thirty-one patients with resistant cancers received 5-60 micrograms/M2/h at three week intervals. The Maximum Tolerated Dose (MTD) was 45 micrograms/M2/hour. Neutropenia was the dose limiting toxicity, with few significant non-myelosuppressive toxicities. Minor responses were seen in 3/31 patients. Pharmacokinetic studies of 9-AC lactone (closed ring) showed substantial interpatient variability with a predicted half-life of 36 hours. A phase I/II trial of the same formulation of 9-AC is ongoing in refractory leukemia. Stomatitis and diarrhea are the non-myelosuppressive dose limiting toxicities. Evidence of antineoplastic activity has been seen in 3/15 patients. A Phase II trial in previously untreated metastatic breast cancer is also underway. A Phase I trial of a colloidal dispersion formulation, not yet completed, is better tolerated with a MTD > 45 micrograms/M2/h as a 72-hour continuous infusion. Evidence of antineoplastic activity has also been demonstrated.

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 combination of bolus doxorubicin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) as a 3-hour infusion is highly active in patients with metastatic breast cancer, but it has considerable cardiotoxicity. In this ongoing study, the potential effect of increasing the interval between administration of a short infusion of doxorubicin followed by a 3-hour infusion of paclitaxel was evaluated. Included were patients with metastatic breast cancer, who received doxorubicin 50 mg/m2 followed by paclitaxel 200 mg/m2 at intervals of 30 minutes, 4 hours, and 24 hours every 3 weeks. As of February 1997, 34 patients have been enrolled, two patients are too early to evaluate, and 13 are continuing treatment. The preliminary response rate is 69% (95% confidence interval, 50% to 84%), ranging from 60% to 80% within the three schedules. The main toxicities consisted of grade 3/4 neutropenia in 65% of all courses, with febrile neutropenia in 2%. Stomatitis and paresthesia were rare. To date, eight of 32 patients have developed abnormal left ventricular ejection fraction values and one patient has developed congestive heart failure. Our preliminary conclusions are that bolus doxorubicin followed by a 3-hour infusion of paclitaxel is highly active against metastatic breast cancer. The potential for cardiotoxicity with the regimen is reduced considerably if the maximum recommended cumulative dose of doxorubicin is reduced to 360 mg/m2 with a maximum single dose of 50 mg/m2.

The aim of this pilot study was to investigate if chemotherapy (CT) followed by the combination of interferon-beta (IFN-beta), retinoids, and tamoxifen could be effective in the treatment of metastatic breast cancer (MBC). Thirty-six patients with stage IV carcinoma of the breast were treated with six courses of cyclophosphamide, 5-fluorouracil, 4-epidoxorubicin, vincristine, and prednisone every 3 weeks (FECPV), followed by two courses of non-cross-resistant drugs, methotrexate, mitomycin C, and mitoxantrone (MMM). Treatment was continued, in responders, with low dose IFN-beta, retinyl palmitate, and tamoxifen until relapse of the disease occurred. Among 36 evaluable patients, 23 achieved a clinical response (64 %) (95 % confidence interval [c.i.] 46 %-79 %), 7 had stable disease (19%), and 6 (17%) progressed. Leukopenia occurred in 15 patients, thrombocytopenia in 6, and anemia in 11. Sixteen patients had nausea/vomiting, stomatitis was observed in 9, and diarrhea occurred in 3. Toxicity from maintenance therapy was mild and mainly hepatic. Median response duration was 31 months (range 5-107). Median overall survival was 32 months (9-108). Our study shows that this combined approach for the treatment of MBC is feasible, with an acceptable toxicity.

The aim of this paper is to evaluate the activity of ifosfamide in previously treated patients with metastatic breast cancer. From June 1991 through November 1992, 29 patients with metastatic breast cancer were treated with single-agent ifosfamide, 2 g/m2 intravenously daily for 5 days, with mesna support. All patients had previously received chemotherapy; all but one had previously received cyclophosphamide. The ifosfamide-mesna regimen was the first-line metastatic regimen in 15 patients, the second-line metastatic regimen in 13 patients, and the third-line metastatic regimen in one patient. Two partial remissions (7%) were observed; both occurred in the first-line metastatic group. The partial remissions were noted in patients who had completed adjuvant cyclophosphamide therapy 60 and 91 months earlier. Both responses were seen in lung metastases. The response durations were 5 and 8 months on continued therapy. The main adverse effects were granulocytopenia, fatigue, nausea, vomiting, and stomatitis. At the dose used in this study, ifosfamide and mesna given without growth-factor support resulted in significant myelosuppression and produced only two partial remissions (7%) in 29 patients. Further study of ifosfamide as an isolated agent in previously treated patients is not warranted.
