    Notes: Summary Schedule dependency of bisantrene was evaluated in refractory metastatic breast cancer. Patients were randomly assigned to receive either a single (S) bolus injection of 300 mg/m2 (37 patients) or an injection of 80 mg/m2 daily for 5 days (Dx5) (35 patients) every 3–4 weeks after stratification by performance status, dominant disease site, and response to prior doxorubicin therapy. All but one patient had received prior doxorubicin. Partial remission (PR) was achieved by 5 of 35 patients (14%) in the S arm and 7 of 35 patients (20%) in the Dx5 arm (P=NS). There were 4 patients who had primary refractoriness to doxorubicin but responded to bisantrene. The median number of courses was two for both arms. The median time to progression was 5 months for the responders in each arm and 3 and 4 months, respectively, for patients who showed no change in the S and Dx5 arms. Myelosuppression was dose-limiting and greater for the Dx5 arm. Drug fever (34% versus 21% of courses; P=0.02) and myalgia (22% versus 10% of courses; P=0.02) were reported more often in the Dx5 arm; malaise was greater in the S arm. Grade 2–3 nausea and vomiting occurred more often in the S arm (40% versus 10% of courses; P〈0.01). Significant hypotension that was not symptomatic occurred in 1 patient in the Dx5 arm. Phlebitis occurred in 3 patients without a central line. One patient who had previously received doxorubicin and mitomycin C developed heart failure, which was controlled with medication. Bisantrene is an effective drug for metastatic breast cancer that has incomplete cross resistance to doxorubicin, and there was no schedule dependency in this study.

    Notes: Abstract Twenty-six patients with metastatic breast cancer who had previously responded to one or more endocrine therapies participated in a clinical trial of the combination of trilostane and hydrocortisone for subsequent disease progression. Of these, one patient achieved complete remission (4%), and five had partial response (19%). The median time to progression from initiation of therapy for responding patients was six months (range: 4 − 32 + months). Major toxicities included nausea/vomiting (16 patients), facial flushing (14), abdominal cramping (11), and oral paresthesia (10). Therapy was discontinued in four patients (15%) because of drug intolerance. Fourteen patients who failed trilostane were treated with aminoglutethimide and hydrocortisone. Six patients showed objective response (PR + MR). These data show that trilostane and hydrocortisone in combination can produce an objective response in a significant fraction of patients and that the combination has a different spectrum of toxicity from aminoglutethimide/hydrocortisone. A small number of patients crossed over to aminoglutethimide showed a few objective responses, suggesting a partial lack of cross-resistance between the two antiadrenal drugs.

    Notes: Summary Thirty-nine evaluable, postmenopausal patients with metastatic breast carcinoma were treated with medroxyprogesterone acetate administered orally at daily doses of 800 mg/day in 29 patients and 400 mg/day in 10 patients. One patient experienced a complete remission and 16 had partial remissions for an objective remission rate of 44%. There was no apparent difference in response between the two dose levels. Median remission duration was 8 months, and median survival for the whole group is expected to exceed 18 months. Increased appetite (66%) and weight gain (97%) were the most common side effects, followed by fluid retention, muscle cramps, and increased blood pressure. Performance status improved and white blood cell and platelet counts increased in the majority of patients. Medroxyprogesterone acetate is an effective hormonal agent in the treatment of metastatic breast cancer.
