Eighty previously treated postmenopausal women with metastatic breast cancer were randomized to receive fadrozole (CGS 16 949A), a new aromatase inhibitor, 1 or 4 mg orally per day. Seventy eight patients were evaluable for toxicity and response. Only mild to moderate toxicity, namely hot flushes (28%), nausea and vomiting (13%), fatigue (8%) and loss of appetite (5%) occurred. Complete response was documented in 10% and partial response in 13% of patients with 45% having a no change status for at least 2 months. The median time to treatment failure is 4.1 months. The median survival is 23.7 months. The median survival is 23.7 months. The response and survival in patients with estrogen receptor positive and estrogen receptor unknown disease were not significantly different. Neither response nor survival was significantly different between the patients receiving 1 or 4 mg of fadrozole per day. Fadrozole is a well tolerated, effective second line treatment for women with metastatic breast cancer.

We evaluated the role of gallium nitrate infusion in the treatment of metastatic breast cancer. Gallium nitrate was administered at 300 mg/m2/day for 7 days every 3 weeks by continuous infusion concomitantly with oral calcium supplement of 500 mg twice daily and oral hydration. Fifteen patients with refractory metastatic breast cancer received such treatment for a total of 30 courses. Median age was 51, and median performance status (Zubrod scale) was 1. These patients had minimal prior chemotherapy (median 1 regimen). All patients were evaluable for toxicity and 14 for response. Nine patients had one to two metastatic sites, five patients had three to four sites. No major objective response was seen, but one patient had a minor response (10 weeks), and another showed no change in disease (16 weeks). Diverse low-grade toxicities were observed, including nausea and vomiting in 11 patients, anorexia in 11, diarrhea in eight, stomatitis in five, dysgeusia in six, musculoskeletal pain in five, skin rash in seven, partially reversible tinnitus and/or mild hearing loss in four and sensory neuropathy in two. A consistent drop in hemoglobin (median of 3.2 g/dL per patient) necessitated blood transfusion in seven patients. There was no granulocytopenia or thrombocytopenia; however, significant lymphopenia was noted. Reversible, moderate nephrotoxicity occurred in two patients. The hypocalcemic effect was consistent, with a median drop in serum calcium of 1.25 mg/dL per course. There was no hepatic toxicity. While no single toxicity was severe, overall toxicity adversely influenced treatment tolerance. Gallium nitrate by continuous infusion, as given in this study, has no activity in metastatic breast cancer.

Fifteen patients with advanced carcinoma of the breast who had failed prior chemotherapy, were treated with recombinant gamma interferon at a dose of 2mg/m2 (1mg = 2.4 X 10(7) international units) intravenously for five consecutive days every other week. The median patient age was 51 and all patients had a performance status of 0-2 (Karnofsky greater than or equal to 50). Thirteen patients had two or three sites of metastatic disease and seven were estrogen receptor positive. No complete or partial responses were noted. Although some patients had brief periods of stable disease, almost all patients progressed after one or two courses. Only one patient was able to receive six courses of induction therapy and a brief course of maintenance. Flu-like symptoms and nausea were seen in all patients; vomiting and anorexia were frequent. Hepatic toxicity manifested by enzyme elevation was common and was most severe in patients with liver metastases. In this study a highly purified biologically active gamma interferon was not associated with anti-tumor activity in previously treated women with metastatic breast cancer.

Nine patients with metastatic breast cancer received 30 x 10(6) I.U. of Interferon - Betaser (Betaseron) intravenously daily times five for two consecutive weeks followed by a two week rest period. Only one patient received more than one such cycle of Betaseron. The drug was well tolerated in eight of these patients. One patient, with liver metastases and liver dysfunction, developed hepatic decompensation during therapy. Toxicity consisted of anorexia, chills, fever, fatigue and nausea with an occasional patient having emesis. One patient developed severe thrombocytopenia, two, significant leukopenia and nine, mild elevations of serum transaminase. Two patients developed beta interferon binding antibodies but none developed neutralizing antibodies. No anti-tumor responses were seen and disease progression occurred rapidly during the four week cycle in eight of nine patients.

45 women (postmenopausal or after former oophorectomy) with metastatic breast cancer resistant to tamoxifen as well as to chemo- and radiotherapy were treated with aminoglutethimide (750 mg or 1000 mg resp. daily) and hydrocortisone (40 mg daily). Treatment resulted in 33% remissions (2 CR + 13 PR) and 53% stabilizations (24 patients) besides a non-responder rate of 13% (6 patients). Side effects (mainly central sedation, possibly exanthema, seldom anorexia, but no hematotoxicity) were observed in 13 patients (29%). Duration of remission lasted for 1 to 24 months (mean duration 10,5 months) while stabilization extended for 2 to 17 months (mean duration 7,7 months). Mechanism of action by enzymatic inhibition of the adrenal steroid hormone synthesis ("medical adrenalectomy") as well as by extra-adrenal diminution of estrogens is considered in detail. Aminoglutethimide provides effective treatment in patients with generalized metastatic breast cancer followed by best outcome in cases with osseous metastases. Clinical results are presented as an approach to successful therapy of advanced breast cancer and an endocrine alternative in tamoxifen resistance as well as a therapeutic possibility in cytotoxic induced pancytopenia.

Nineteen patients with advanced refractory metastatic breast cancer no longer responsive to chemotherapy were treated in the first phase II efficacy trial of recombinant leukocyte A interferon (IFL-rA), a highly purified single molecular species of alpha interferon prepared by recombinant DNA methods. Patients received a previously determined maximum tolerated dose for this agent (50 X 10(6) U/m2 body surface area) by intramuscular injection three times weekly for up to 3 months. The symptoms of toxicity observed in this trial resemble those previously reported for alpha interferons and include fever, chills, fatigue, anorexia, and leukopenia. All patients required dose reductions, most often for reasons of severe fatigue. Of the 17 patients evaluable for tumor response, one patient had stable disease and 16 had evidence of tumor progression. We conclude that IFL-rA is not an active agent in the treatment of advanced, refractory breast cancer when used at a maximum tolerated dose on this treatment schedule.

Thirty-three patients with advanced breast cancer were treated with a recombinant alpha interferon (rIFN-alpha 2). All patients were ambulatory (performance status greater than or equal to 50 Karnofsky scale) and almost all had received previous chemotherapy. Large intravenous dosages of 30 to 50 X 10(6) IU/m2 were given for five consecutive days every two to three weeks to 22 patients and smaller subcutaneous dosage of 2 X 10(6) IU/m2 three times a week to 11 patients. No complete or partial responses were seen. Two patients had stable disease and the remainder progressed. Flu-like syndromes were seen in all patients. Nausea, vomiting, and anorexia were frequent. Hypotension and confusion were noted in six and five patients, respectively. Life-threatening leukopenia was noted in two patients receiving intravenous dosage and thrombocytopenia was noted in one; no sepsis or bleeding complications were noted. In this study, a highly purified and biologically active rIFN-alpha 2 was not associated with activity in previously treated women with metastatic breast cancer.

Twenty-one evaluable patients with metastatic breast cancer received three pulses of intravenous cyclophosphamide, escalating from 1.5 g/m2 to 2.5 g/m2 in the second and third courses. There were eight partial remissions (34.7%), but most were of short duration. All responding patients had soft tissue or nodal disease, but additional sites of response were bone (three cases), liver and lung (one case each). Marked leucopaenia (median WBC 0.7 X 10(9)/L) occurred 10-12 days after the higher doses (2.5 g/m2) and was associated with nine episodes of severe infection in five patients. Marked vomiting and anorexia led to significant weight loss (mean 4.5 kg) in half the patients, and alopecia was universal. In metastatic breast cancer cyclophosphamide seems to have a shallow dose response curve and high intermittent dosage seems to have no advantage over chronic daily administration.

Thirty-three patients with metastatic breast cancer who have failed prior combination chemotherapy including adriamycin, cyclophosphamide, 5-fluorouracil and methotrexate, were treated with AZQ given on a 5-day I.V. schedule repeated every 4 weeks. The starting doses were 6 or 8 mg/m2/day for poor- and good-risk patients, respectively. There were two partial responses among 29 evaluable patients. Both had soft tissue and/or lymph node involvement. Six patients had stable disease. Myelosuppression, predominantly thrombocytopenia, was dose-limiting. Other toxicities were mild, including nausea, vomiting, anorexia, diarrhea, stomatitis, and malaise. Our results indicate that AZQ given on the 5-day schedule is unlikely to be effective in the treatment of refractory breast cancer.

A phase II trial was conducted in 57 patients with advanced metastatic breast cancer given 2-N-methyl 9-hydroxy-ellipticine (NMHE) as 100 mg/m2 weekly. Evaluation of response, after at least 4 injections, was possible in 46 patients. Two complete regressions (of 3 and 12 months) and 7 regressions of over 50 p. cent were observed, a total regression rate of 19 p. cent. Regression was mainly observed in cutaneous or subcutaneous metastases. No objective regression was noted for pulmonary or hepatic metastases. Bone metastases were not taken in account when assessing response to treatment. Absence of haematological changes must be emphasized. The most frequent side effects were anorexia, nausea +/- vomiting and dryness of mouth. Major toxicity was intravascular haemolysis, observed in 6 of 175 patients receiving NMHE in the Institut Gustave-Roussy, always controlled by symptomatic treatment. This product, of acceptable efficacy in breast cancer treatment, will probably occupy an original place in anti-cancer chemotherapy because of its lack of myelotoxicity.
