Object. Recent studies have suggested a high incidence of cognitive deficits in patients undergoing high-dose chemotherapy, which appears to be dose related. Whole-brain radiotherapy (WBRT) has previously been associated with cognitive impairment. The authors attempted to use gamma knife radiosurgery (GKS) to delay or avoid WBRT in patients with advanced breast cancer treated with high-dose chemotherapy and autologous bone marrow transplantation (HDC/ABMT) in whom brain metastases were diagnosed. Methods. A retrospective review of our experience from 1996 to 2001 was performed to identify patients who underwent HDC/ABMT for advanced breast cancer and brain metastasis. They were able to conduct GKS as initial management to avoid or delay WBRT in 12 patients following HDC/ABMT. All patients were women. The median age was 48 years (range 30–58 years). The Karnofsky Performance Scale score was 70 (range 60–90). All lesions were treated with a median prescription dose of 17 Gy (range 15–18 Gy) prescribed to the 50% isodose. Median survival was 11.5 months. Five patients (42%) had no evidence of central nervous system disease progression and no further treatment was given. Four patients were retreated with GKS and three of them eventually received WBRT as well. Two patients were treated with WBRT as the primary salvage therapy. The median time to retreatment with WBRT was 8 months after the initial GKS. Conclusions. Gamma knife radiosurgery can be effectively used for the initial management of brain metastases to avoid or delay WBRT in patients treated previously with HDC, with acceptable survival and preserved cognitive function.

Aims and background The study was designed to define the activity of the combination of cisplatin and etoposide as third-line chemotherapy for advanced breast cancer and to investigate the role of the dosage of cisplatin on the effectiveness of the combination. Methods Ninety-five eligible patients with advanced breast cancer who had failed or relapsed on two previous lines of chemotherapy were randomized to receive cisplatin at a high dose (100 mg/m2 i.v. day 1, arm A) or a low dose (60 mg/m2 day 1, arm B), combined with etoposide (100 mg/m2 i.v. days 4, 6 and 8). Cycles were repeated every 3 weeks. Results Of the 78 patients evaluable for response (39 in arm A and 39 in arm B), 9 (12%) showed complete or partial response, 5 (13%) in the high-dose arm and 4 (10%) in the low-dose arm. One complete response was seen in the high-dose arm and none in the low-dose arm. The only 2 patients with brain involvement showed an objective response (one CR in arm A and one PR in arm B). Median time to progression was 14 weeks in arm A and 10 weeks in arm B, median duration of remission 28 and 34 weeks, and survival 36 and 35 weeks, respectively. The differences were not significant. As expected, the patients in the high-dose arm experienced more severe toxicity. One toxic death was observed in each arm due to sepsis in agranulocytosis. The difference was statistically significant regarding nausea and vomiting. Neurotoxicity and ototoxicity were not relevant problems in this patient setting. Conclusions Considering the very poor prognostic factors presented by these patients, the combination showed a certain activity, and further evaluation in earlier stages of disease is warranted. A particular responsiveness on brain metastases is suggested. The dose of cisplatin was not proven to be of significant importance.

PURPOSE To explore further the efficacy of high-dose toremifene in patients with advanced breast cancer who had failed to respond to tamoxifen or whose disease had progressed on tamoxifen. PATIENTS AND METHODS One hundred two perimenopausal or postmenopausal women with metastatic breast cancer refractory to tamoxifen were entered onto a phase II clinical trial of toremifene at a dose of 200 mg/d. The study patients consisted of 28 primarily refractory patients; 43 patients who had relapsed after a prior tamoxifen response; and 31 patients who had relapsed while receiving adjuvant tamoxifen. This was a heavily pretreated group of patients, with 65% having failed chemotherapeutic attempts and 72% having failed two or more hormonal therapies. Forty-nine percent of patients had visceral dominant disease. RESULTS The objective response rate was 5% (95% confidence interval [CI], 3% to 7%). The median time to treatment failure (TTF) was 10.9 months for the five responders. An additional 23% of patients had stable disease for a median TTF of 7.8 months, whereas the patients who experienced treatment failure had a median TTF of 2.1 months. Whether those patients with stable disease derived clinical benefit or simply had slow progression in an intrinsically indolent disease presentation is uncertain. Common toxicities were generally mild and similar to those encountered with tamoxifen. CONCLUSION We conclude that there is major cross-resistance between tamoxifen and toremifene and that only occasional tamoxifen-refractory patients will have objective responses to toremifene.

PURPOSE: To examine the impact of consolidation radiotherapy (RT) after high-dose chemotherapy with autologous bone marrow rescue (HDC) in patients with advanced breast cancer. PATIENTS AND METHODS: Between 1988 and 1994, 425 patients with metastatic or recurrent breast cancer received doxorubicin, fluorouracil, and methotrexate (AFM) induction chemotherapy in a single-institution prospective trial. One hundred patients who achieved a complete response were randomized to receive HDC (cyclophosphamide, cisplatin, carmustine), with autologous bone marrow rescue immediately after AFM, or to observation, with HDC to be administered at next relapse. Seventy-four of the 100 became eligible for RT; 53 received consolidation RT (HDC RT+ and 21 did not (HDC RT−). The assignment of RT was not randomized. The RT+ and RT− groups were similar with regard to number of involved sites, the fraction of patients with only local-regional disease, age, and interval since initial diagnosis. Local control at previously involved sites and distant sites was assessed with extensive radiologic and clinical evaluations at the time of first failure or most recent follow-up. The impact of RT on failure patterns, event-free survival, and overall survival was evaluated. RESULTS: Sites of first failure were located exclusively at previously involved sites in 28% of RT+ patients versus 62% of RT− patients (P < .01). Event-free survival at 4 years was 31% and 21% in the RT+ and RT− groups, respectively (P = .02). Overall survival at 4 years was 30% and 16% in the RT+ and RT− groups, respectively (P = .20). CONCLUSION: Patients with advanced breast cancer who were treated with HDC without RT failed predominantly at the initial sites of disease. The addition of RT appeared to reduce the failure rate at initial disease sites and may improve event-free and overall survival. Our observations await verification in a trial in which assignment to RT is randomized.
