Purpose: Breast cancer heterogeneity dictates lengthy follow-up to assess outcomes. Efficacy differences for three regimens that are based on adjuvant cyclophosphamide, methotrexate, and fluorouracil (CMF) are presented in this article, but cancer recurrence sites, time of relapse, subsequent primary cancers, and causes of death in the natural history of node-positive breast cancer are emphasized. Patients and Methods: Beginning in 1975, 905 patients with node-positive cancer were randomly assigned to receive CMF or two regimens of CMF plus other agents. Median follow-up is 22.6 years. The natural-history analysis was performed on a subset of 814 patients. Results: Eighty percent of the 599 women known to have died, died of metastatic breast cancer. Only 8.5% of the deceased women died of a cause other than breast cancer, a second or third cancer, or adjuvant chemotherapy toxicity. One hundred five women (12.8%) developed other primary cancers, with 49 (46.6%) occurring in the contralateral breast. Therapeutic efficacy differences of the CMF regimens reported earlier have been maintained more than 20 years later. For certain subsets, the five-drug regimen had advantages over CMF. Bone was the most common recurrence site. The longest interval to relapse has been 23.5 years, and 18% of those who relapsed did so more than 10 years later. Conclusion: Despite adjuvant chemotherapy, a large majority (80%) of women with node-positive breast cancer die of the disease, and many recurrences develop more than 10 years later. CMF plus vincristine and prednisone provides a benefit compared with CMF, but the magnitude varies with the number of involved nodes. Outcome trends in earlier analyses of this study were maintained even years later.

10610 Background: Recently, adjuvant AC followed by paclitaxel has improved disease-free survival (DFS) or overall survival (OS) of node-positive breast cancer. Although adjuvant TAC, as compared with FAC, significantly improves DFS and OS rate in node-positive breast cancer, AC→T has not been yet compared with FAC. Since 2001, we discussed the options of adjuvant CAF versus AC→T with patients who had 4 or more positive axillary nodes. We evaluated the efficacies of adjuvant CAF and AC→T, retrospectively. Methods: Between September 2001 and July 2004, a total of 1,394 patients underwent surgery and received adjuvant chemotherapy. Among them, 253 (18.1%) patients had 4 or more than axillary nodes and received either six cycles of CAF (n = 116) or 4 cycles of AC→T) (n = 137). The medical records and pathologic data of these patients were reviewed, retrospectively. Results: Median age of all patients was 46 years (range, 22∼76 years). The two groups were well balanced in terms of demographic and tumor characteristics. With a median follow-up period of 24 months (range, 6∼90 months), 49 (19.4%) patients had disease recurrence including 27 (23.3%) in CAF group and 22 (16.1%) in AC→T group (p = 0.155). The 3 year-DFS rate was 68.3% in CAF group and 71.1% in AC→T group (p = 0.9366), and the estimated 3-year OS rate was 90.3% and 92.3%, respectively (p = 0.8237). There was no significant difference in 3-year DFS rate according to hormone-receptor status. Febrile neutropenia occurred in 11 (9.6%) patients in CAF group and 7 (5.1%) patients in AC→T group (p = 0.222). Conclusion: Our data suggest that there is no significant difference in DFS or OS rates between six cycles of CAF and 4 cycles of AC followed by 4 cycles of paclitaxel as adjuvant chemotherapy in patients with 4 or more than involved axillary nodes. However, long-term follow-up period and prospective studies are needed to define better regimen. No significant financial relationships to disclose.

Purpose Certain anthracycline-containing adjuvant chemotherapy regimens are associated with improved relapse-free survival (RFS) and overall survival (OS) compared with the classic regimen of cyclophosphamide, methotrexate, and fluorouracil in women with early-stage breast cancer. Patients and Methods Between 1989 and 1993, 710 pre- and perimenopausal women with axillary node–positive breast cancer were randomly assigned to either cyclophosphamide 75 mg/m2 orally days 1 through 14, epirubicin 60 mg/m2 intravenously days 1 and 8, and fluorouracil 500 mg/m2 intravenously days 1 and 8 (CEF) or CMF (cyclophosphamide 100 mg/m2 orally days 1 through 14, methotrexate 40 mg/m2 intravenously days 1 and 8, and fluorouracil 600 mg/m2 intravenously days 1 and 8). On the basis of follow-up to May 1997 (median follow-up time, 59 months), there was a statistically significant improvement in RFS and OS for CEF compared with CMF. Results The trial results are now updated, with a median follow-up of 10 years for live patients. The 10-year RFS is 52% for patients who received CEF compared with 45% for CMF patients (hazard ratio [HR] for CMF v CEF = 1.31; stratified log-rank, P = .007). The 10-year OS for patients who received CEF and CMF are 62% and 58%, respectively (HR for CMF v CEF = 1.18; stratified log-rank, P = .085). The rates of acute leukemia have not changed since the original report, whereas the rates of congestive heart failure are slightly higher but acceptable (four patients [1.1%] in the CEF group v one patient [0.3%] in the CMF group). Conclusion The previously demonstrated benefit of CEF compared with CMF adjuvant chemotherapy is maintained with longer follow-up in the MA5 trial.

Radiological Staging

Background: In 2012, the American Society for Clinical Oncology (ASCO) identified five key opportunities in oncology to improve patient care, recommending against imaging tests for the staging of patients with early breast cancer (EBC) at low risk for metastases. Similarly, the European Society of Medical Oncology (ESMO) guideline does not support radiological staging in asymptomatic EBC (aEBC). The purpose of this study was to assess local practice and outcomes of staging investigations (SIs) in aEBC at the Cancer Centre of Southeastern Ontario (CCSEO). Methods: A retrospective electronic and paper chart review was undertaken to identify all aEBC patients treated at our institution between January 2012 and December 2014. Patients with pathological staging of T1-T2 and N0-1 with any receptor status were included. We collected patient demographics, treatment and pathologic tumor characteristics. The use and outcomes of initial and follow-up SIs were recorded. Data were analyzed to determine associations between the use of SIs and clinical characteristics (chi-square tests, independent samples t-tests and Mann–Whitney U tests). Results: From 2012 to 2014, 295 asymptomatic EBC patients were identified. The mean age was 64, 81% were postmenopausal and 76% had breast conserving surgery. Stage distribution was as follows: stage I 42%, stage IIA 37% and stage IIB 21%. Receptor status was as follows: ER+ 84%, HER2+ 13% and triple negative 12%. Adjuvant chemotherapy was received by 36%, Trastuzumab by 10% and endocrine therapy by 76% of patients. Baseline SIs were performed in 168 patients (57%) for a total of 332 tests. Overt metastatic disease was found in five patients (one bone scan and four CT scans). Seventy-one out of the 168 patients (42%) who received initial staging imaging underwent 138 follow-up imaging tests, none of which were diagnostic for metastases. Nine patients with suspicious CT findings underwent biopsies, of which four were malignant (one metastatic breast cancer and three new primaries). Factors significantly associated with SI were as follows: younger age (p = 0.001), premenopausal status (p = 0.01), T2 stage (p < 0.001), N1 stage (p < 0.001), HER2 positive (p < 0.001), triple negative status (p = 0.007) and use of adjuvant chemotherapy (p < 0.001). Conclusions: Over a 3-year period at our institution, more than 50% of aEBC patients underwent a total of 470 initial and follow-up staging tests, yielding a cancer diagnosis (metastatic breast cancer or second primary cancer) in four patients. We, therefore, conclude that routine-staging investigations in aEBC patients have low diagnostic value, supporting current guidelines that recommend against the routine use of SI in this population.

The Mean

PURPOSE: In this multicenter trial, toremifene 40 mg/d was compared with tamoxifen 20 mg/d, both given orally for 3 years to postmenopausal, axillary node–positive women after breast surgery. PATIENTS AND METHODS: The first 899 patients (toremifene, n = 459; tamoxifen, n = 440) of the total of 1,480 patients accrued to the trial were included in this scheduled safety analysis. The mean follow-up time was 3.4 years. RESULTS: The two treatment groups were well balanced with respect to patient and disease characteristics. The subjective side-effect profile was similar in both treatment groups. Slightly more vascular complications (deep vein thromboses, cerebrovascular events, and pulmonary embolisms) were seen among tamoxifen-treated patients (5.9%) as compared with toremifene-treated patients (3.5%) (P = .11), whereas bone fractures (P = .09) and vaginal leukorrhea (P = .05) were more common in the toremifene group. The number of subsequent second cancers was similar. The breast cancer recurrence rate was 23.1% (n = 106) in the toremifene group and 26.1% (n = 115) in the tamoxifen group (P = .31). When only patients with estrogen receptor (ER)–positive cancer were considered (n = 556), the risk for breast cancer recurrence was nonsignificantly lower among the toremifene-treated women, with a hazards ratio of 0.74 (90% confidence interval, 0.52 to 1.04; P = .14). The mean time to breast cancer recurrence and overall survival were similar in both groups. CONCLUSION: The side-effect profile of toremifene resembles that of tamoxifen. The efficacy of toremifene seems to be no less than that of tamoxifen. The trend for fewer breast cancer recurrences in the ER-positive subgroup is encouraging, but a longer follow-up is needed to confirm this.
