    Notes: We conducted a single-institution study to determine whether local therapy plus six cycles of chemotherapy with 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) followed by 5 years of tamoxifen is superior to local treatment alone in terms of disease-free survival (DFS) and overall survival (OS) in patients with stage IV breast cancer with no evidence of disease (stage IV-NED breast cancer). Patients with breast cancer were eligible if they had histologic proof of a locoregional or distant recurrence that had been curatively resected, irradiated, or both and had no other evidence of disease. Patients who had received prior anthracycline therapy were not eligible. All patients received six cycles of intravenous FAC, with cycles repeated every 3 weeks. After completion of chemotherapy, patients whose tumors had not previously demonstrated resistance to tamoxifen and had positive or unknown estrogen receptor status received tamoxifen 20 mg by mouth daily for 5 years. Patients in this study were compared with a historical control population (patients with stage IV-NED breast cancer who never received systemic therapy) as well as with the patients in two previously reported trials of chemotherapy for stage IV-NED disease. Forty-seven patients were registered, but only 45 were evaluable. There was a highly statistically significant difference ( p 〈 0.001) in OS and DFS among the four groups, with patients in our most recent study having the best OS and DFS at 3 years compared with the control group (84% vs. 55% and 66% vs. 11%, respectively). When patients in all four groups were analyzed together in search of prognostic factors, we found that patients whose primary tumors had negative axillary lymph nodes had a statistically significant improvement in OS and DFS (p 〈 0.01) compared with patients with positive axillary lymph nodes. No survival differences were found between patients with positive and those with negative hormone receptor status. This study demonstrates a benefit in terms of OS and DFS for patients with stage IV-NED breast cancer who receive doxorubicin-based adjuvant chemotherapy. The benefit was greater on patients with node-negative primary tumors. In patients with stage IV-NED disease, doxorubicin-based chemotherapy should be considered standard treatment after adequate local control is achieved.

    Notes: Abstract. Droloxifene (3-hydroxytamoxifen) is a new, nonsteroidal antiestrogen. In comparison with tamoxifen, it has a 10- to 64-fold higher affinity for the estrogen receptor and has shown a lower estrogenic and higher antiestrogenic effect in experimental studies. The objective of this study was to determine the toxicity (and its reversibility) of droloxifene given at different doses to patients with advanced metastatic breast cancer refractory to conventional endocrine therapy and chemotherapy. In this study, 30 patients were treated in groups of 6 at 5 different doses (20, 40, 100, 200, and 300 mg) by mouth once a day. Toxic effects included hot flashes, nausea, and fatigue and were not dose-related. Toxicity did not require any dose reduction or discontinuation of therapy. There was one episode of deep venous thrombosis and pulmonary embolism. There was no complete or partial response in this study, but four patients showed a minor response (13%). These data illustrate that this drug is well tolerated and needs to be further evaluated in phase II and III studies.

    Notes: Abstract Purpose: To review the 20 years of experience at M. D. Anderson Cancer Center with a combined-modality approach against inflammatory breast carcinoma. Patients and methods: A total of 178 patients with inflammatory breast carcinoma were treated in the past 20 years at M. D. Anderson Cancer Center by a combined-modality approach under four different protocols. Each protocol included induction chemotherapy, then local therapy (radiotherapy or mastectomy), then adjuvant chemotherapy, and, if mastectomy was performed, adjuvant radiotherapy. Chemotherapy consisted of 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) with or without vincristine and prednisone (VP). In protocol D, patients received an alternate adjuvant chemotherapy regimen, methotrexate and vinblastine (MV), if they did not have a complete response (CR) to induction chemotherapy. Results: The median follow-up of live patients in group A was 215 months, in group B 186 months, in group C 116 months, and in group D 45 months. An estimated 28% of patients were currently free of disease beyond 15 years. At the time of analysis, 50 patients were alive without any evidence of disease. A further 12 patients died of intercurrent illness, and 15 patients were followed beyond 10 years without recurrence of disease. Among initial recurrence, 20% of patients had local failure, 39% systemic failure, and 9% CNS recurrence. Initial response to induction chemotherapy was an important prognostic factor. Disease-free survival (DFS) at 15 years was 44% in patients who had a CR to induction chemotherapy, 31% in those who had a partial response (PR), and 7% in those who had less than a PR. There was no improvement in overall survival (OS) or DFS among patients who underwent alternate chemotherapy (MV) compared with those who did not. Using surgery and radiotherapy as opposed to radiotherapy alone as local therapy did not have an impact on the DFS or OS rate. Conclusion: These long-term follow-up data show that with a combined-modality approach a significant fraction of patients (28%) remained free of disease beyond 15 years. In contrast, single-modality treatments yielded a DFS of less than 5%. Thus, using combined-modality treatment (chemotherapy, then mastectomy, then chemotherapy and radiotherapy) is recommended as a standard of care for inflammatory breast carcinoma.

    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 Purpose: Early phase II evaluation of intravenous bolus mitoxantrone indicated objective response rates of 17–36% in patients with metastatic breast cancer. Subsequently, it has been suggested that continuous infusion may be the optimal way to administer this drug in order to achieve maximal cytotoxic effect with minimal toxicity. We present the results of a phase II study that evaluated the efficacy and side effects of mitoxantrone administered at the maximally tolerated dose by continuous infusion in patients with metastatic breast cancer. Methods: This study included 16 patients with metastatic breast cancer and limited previous therapy for their metastatic disease. Mitoxantrone, 1.5 mg/m2 per day, was given by continuous intravenous infusion for 14 consecutive days repeated every 21 days with concomitant granulocyte colony-stimulating factor support. Dose escalation was allowed. Results: No complete tumor response was seen. Two patients (13%, CI 0–29%) had a partial response, nine patients (56%) had progressive disease and the remaining five patients (31%) had stable disease on therapy. The major dose-limiting side effect was myelotoxicity. Two of the 16 patients (13%) experienced asymptomatic cardiotoxicity that required discontinuation of therapy. Conclusions: Our results indicate limited antitumor activity and significant toxicity of mitoxantrone given by continuous infusion as second-line chemotherapy for metastatic breast cancer. The objective response rate documented in this study is inferior to response rates reported with other second-line regimens, particularly the taxanes, now available for this patient population.

    Notes: Abstract Fourteen consecutive female patients with metastatic breast cancer received a total of 31 courses of fazarabine at a dose of 2 mg/m2/hour×72 hours (48 mg/m2/day×3) as a continuous infusion. There were no responses seen, although one patient achieved stability of her disease for five courses. Because of encouragingin vitro results and the primarily hematologic dose-limiting toxicity, further study in combination with colony stimulating growth factors might be of interest.
