PURPOSE The use of leucovorin (LV) to modulate fluorouracil (FU)-mediated inhibition of thymidylate synthase has been shown both in vitro and in vivo to improve the antitumor activity of this drug. Based on our previous demonstration that this combination was active in heavily pretreated patients with prior FU exposure, we performed a phase II study of FU and high-dose intravenous calcium LV in patients with advanced breast cancer who had been exposed to no more than one prior chemotherapy regimen. PATIENTS AND METHODS Fifty-one female patients with metastatic breast cancer were entered onto this trial. Patients with metastatic disease limited to soft tissue, lymph nodes, skin, and pulmonary nodules were allowed no prior chemotherapy for advanced disease. Those with metastases in the liver or a lymphangitic pattern on chest x-ray were allowed either a single prior regimen for advanced disease or no therapy for metastatic disease if less than 1 year had elapsed since the completion of adjuvant chemotherapy. FU was given daily for 5 days at 400 mg/m2/d with calcium LV, 500 mg/m2/d, beginning 24 hours before and continuing 12 hours after the first and last FU doses, respectively. RESULTS The overall objective response rate among 45 eligible patients was 36% (95% confidence interval, 22% to 51%). Fourteen of 31 patients in the soft tissue category responded (45%), and two of 14 in the visceral category experienced an objective response (14%). The median response duration was 5 months. Toxicities were moderate leukopenia and mucositis. CONCLUSIONS FU plus LV is an active first-line regimen with antitumor efficacy comparable to that of the anthracyclines, which warrants further exploration in combination with other agents active in advanced breast cancer. FU plus LV in this schedule is also an excellent alternative for patients with medical contraindications to more intensive combination chemotherapy regimens.

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 A phase II study of paclitaxel and cisplatin in patients with advanced breast cancer was performed to determine the objective response rate and make further observations about the toxicity of this regimen. PATIENTS AND METHODS Patients were required to have histologically proven adenocarcinoma of the breast with no more than one chemotherapeutic treatment for advanced disease. Treatment consisted of paclitaxel 200 mg/m2 administered as a 24-hour intravenous (i.v.) infusion followed by cisplatin 75 mg/m2 i.v. Patients received granulocyte colony-stimulating factor (G-CSF) 5 micrograms/kg subcutaneously on day 3 until WBC recovery. Cycles were repeated every 21 days. Patients continued to receive therapy until disease progression or unacceptable toxicity. RESULTS Forty-four patients entered the trial. Forty-two patients were assessable for response. Nineteen patients (43%) had no prior chemotherapy and 41 had no chemotherapy for metastatic disease. The median number of cycles administered per patient was five (range, one to seven). There were five complete responses (CRs) (11.9%) and 17 partial responses (PRs) (40.5%), with an overall response rate of 52.4% (95% confidence interval [CI], 36.4% to 68.0%). Nine patients had stage III disease. The response rate for this group was 66.7% (95% CI, 33.0% to 92.5%), with three CRs and three PRs. Among 35 patients with stage IV disease, there were two CRs and 14 PRs, with an overall response rate of 48.5% (95% CI, 30.8% to 66.5%). Overall, the median response duration was 10.6 months. Thirty patients (68%) developed transient grade 4 neutropenia. Cumulative neuropathy was the major dose-limiting toxicity. After five cycles of chemotherapy, 96% of patients had at least grade 1 neurotoxicity and 52% had at least grade 2 neurotoxicity. One patient had a toxic death after cycle 1 of therapy. CONCLUSION The combination of paclitaxel and cisplatin as first-line chemotherapy for women with advanced breast cancer is an active regimen. However, the cumulative neurotoxicity was significant and dose-limiting in the majority of patients.

Anthracycline Cardiotoxicity

PURPOSE We conducted a randomized trial to evaluate primarily the cardioprotective effect of dexrazoxane (DEX) in patients with advanced breast cancer and soft tissue sarcomas (STS) treated with high-dose epirubicin (EPI). We wished also to determine the value of radioimmunoscintigraphy (RIS) in the assessment of anthracycline cardiotoxicity. PATIENTS AND METHODS Patients with breast cancer (n = 95) or STS (n = 34) received EPI 160 mg/m2 by intravenous (I.V.) bolus every 3 weeks with or without DEX 1,000 mg/m2 I.V. Cardiac monitoring included multigated radionuclide (MUGA) scans with determination of resting left ventricular ejection fraction (LVEF), and RIS with indium 111 antimyosin monoclonal antibodies. RESULTS In either disease, antitumor response rates, time to progression, and survival did not significantly differ between the two arms. There was little difference in noncardiac toxicity for the two treatment groups. All methods of cardiac evaluation clearly documented the cardioprotective effect of DEX. Four patients developed congestive heart failure (CHF), all in the EPI arm. The decrease in LVEF from baseline was significantly greater in the control group. An abnormal antimyosin uptake was observed early in both arms and progressively increased during treatment. However, this increase was significantly higher in the EPI group (P = .004). CONCLUSION DEX significantly protects against the development of cardiotoxicity when high single doses of EPI are used. Apparently, there was no evidence of an adverse impact of DEX on antitumor activity. Although RIS is a sensitive technique in detecting anthracycline cardiac damage, its specificity is low and it cannot be considered a primary test for guiding anthracycline treatment.

Background: Tumor progression following endocrine therapy is considered to indicate resistance to endocrine drugs due to a variety of mechanisms. An insufficient dose of endocrine drugs is one of the causes for treatment failure in some patients with high hormone-receptor (HR)-expressing advanced breast cancer. This study aimed to explore the efficacy of high-dose tamoxifen (TAM) treatment in patients with advanced breast cancer with highly expressed HR. Materials & methods: This was a single-arm, phase II pilot study that enrolled patients with advanced breast cancer with high HR expression (estrogen receptor ⩾60% and/or progesterone receptor ⩾60%) following routine endocrine therapy. All enrolled patients received a high-dose of TAM (100 mg/day) until disease progression. The primary endpoint was progression-free survival (PFS). The secondary endpoints included objective response rate (ORR), clinical benefit rate (CBR), overall survival (OS), and safety. Exploratory endpoints included the predictive value of 16α-18F-17β-fluoroestradiol quantitative positron emission tomography/computed tomography (18F-FES PET/CT) for treatment efficacy. Results: A total of 30 patients were enrolled between September 2017 and February 2019. The median PFS was 6 months [95% confidence interval (CI) 4.9–7.1] and the median OS was 15.6 months (95% CI 8.3–22.9). Five patients experienced a partial response (PR) and none experienced a complete response (CR), with an ORR of 16.7% and CBR of 33.3%. No severe adverse events were observed. Lesions with 18F-FES maximum standardized uptake value (SUVmax) ⩾4 had a significantly longer PFS [median 9.2 months, (95% CI 6.9–11.6)] compared with lesions with a 18F-FES SUVmax <4 [median 4.8 months, (95% CI 3.9–5.6); p = 0.022]. Conclusion: A high-dose of TAM is effective and safe for patients with advanced breast cancer with high HR expression. 18F-FES SUVmax values may predict the local clinical benefits of high-dose TAM .

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.

AbstractIn MONARCH 3, continuous dosing of abemaciclib with an aromatase inhibitor (AI) conferred significant clinical benefit to postmenopausal women with HR+, HER2− advanced breast cancer. We report data for clinically prognostic subgroups: liver metastases, progesterone receptor status, tumor grade, bone-only disease, ECOG performance status, and treatment-free interval (TFI) from an additional 12-month follow-up (after final progression-free survival [PFS] readout). In the intent-to-treat population, after median follow-up of approximately 39 months, the updated PFS was 28.2 versus 14.8 months (hazard ratio [HR], 0.525; 95% confidence interval, 0.415–0.665) in abemaciclib versus placebo arms, respectively. Time to chemotherapy (HR, 0.513), time to second disease progression (HR, 0.637), and duration of response (HR, 0.466) were also statistically significantly prolonged with the addition of abemaciclib to AI. Treatment benefit was observed across all subgroups, as evidenced by objective response rate change from the addition of abemaciclib to AI, with the largest effects observed in patients with liver metastases, progesterone receptor-negative tumors, high-grade tumors, or TFI < 36 months. Extended follow-up in the MONARCH 3 trial further confirmed that the addition of abemaciclib to AI conferred significant treatment benefit to all subgroups, including those with poorer prognosis.
