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.

21072 Background: Axillary lymph node metastasis has proven to be the most important factor affecting overall survival (OS) and disease free survival (DFS) in patients with breast cancer. Recent evidence suggests that axillary lymph node ratio (LNR) may be at least as important as absolute number of involved lymph nodes in predicting OS and DFS. The aim of this retrospective study is to evaluate the impact of axillary nodal ratios in node-positive breast cancer as a prognostic factor for survival. Methods: Data from 1181 patients with stage I, II and III breast cancer diagnosed at AUBMC between 1990 and 2001 were studied. The median age at diagnosis was 50 years (23 - 88); the median number of lymph nodes dissected was 17 (0 - 49). Survival was compared in 737 patients with node-positive disease according to a LNR below or more than 0.25 (defined as number of involved lymph nodes divided by total dissected axillary lymph nodes). Results: Patients with LNR = 0.25 had a median follow-up of 30 months (1.2–156) and a median DFS of 26 months (1–156). The 5-year survival was 26.2% (94/358) and the 5-year DFS was 22.9% (82/358). Patients with LNR <0.25 had a median follow-up of 36 months (1.2–157) and a median DFS of 36 months (1–157). The 5-year survival of 33.2% (245/737) and the 5-year DFS was 29.8 % (220/737). LNR showed significance as a continuous variable and a categorical variable (0, < 0.25, and = 0.25) with a p < 0.001 Conclusions: LNR significantly predicts OS and DFS in node-positive primary breast cancer.

Abstract Background Due to the lack of clinical trials on the efficacy of chemotherapy in older patients, an optimal treatment strategy has not been developed. We investigated whether adjuvant chemotherapy could improve the survival of older patients with breast cancer in Japan. Methods We retrospectively analyzed data of patients with breast cancer aged ≥ 70 years who underwent breast cancer surgery in eight hospitals between 2008 and 2013. Clinical treatment and follow-up data were obtained from the patients’ medical electric records. Results A total of 1095 patients were enrolled, of which 905 were included in the initial non-matched analysis. The median age and follow-up period were 75 (range 70–93) and 6.3 years, respectively. Of these patients, 127 (14%) received adjuvant chemotherapy (Chemo group) while the remaining 778 (86%) did not (Control group). The Chemo group was younger (mean age in years 73 vs 76; P < 0.0001), had a larger pathological tumor size (mean mm 25.9 vs 19.9; P < 0.0001), and more metastatic axillary lymph nodes (mean numbers 2.7 vs 0.7; P < 0.0001) than the Control group. The disease-free survival (DFS) and overall survival (OS) did not differ significantly between the two groups (P = 0.783 and P = 0.558). After matched analyses, DFS was found to be significantly prolonged with adjuvant chemotherapy (P = 0.037); however, OS difference in the matched cohort was not statistically significant (P = 0.333). Conclusion The results showed that adjuvant chemotherapy was associated with a reduced risk of recurrence, but survival benefits were limited.

Abstract Purpose Obesity associated fat infiltration of organ systems is accompanied by organ dysfunction and poor cancer outcomes. Obese women demonstrate variable degrees of fat infiltration of axillary lymph nodes (LNs), and they are at increased risk for node-positive breast cancer. However, the relationship between enlarged axillary nodes and axillary metastases has not been investigated. The purpose of this study is to evaluate the association between axillary metastases and fat-enlarged axillary nodes visualized on mammograms and breast MRI in obese women with a diagnosis of invasive breast cancer. Methods This retrospective case–control study included 431 patients with histologically confirmed invasive breast cancer. The primary analysis of this study included 306 patients with pre-treatment and pre-operative breast MRI and body mass index (BMI) > 30 (201 node-positive cases and 105 randomly selected node-negative controls) diagnosed with invasive breast cancer between April 1, 2011, and March 1, 2020. The largest visible LN was measured in the axilla contralateral to the known breast cancer on breast MRI. Multivariate logistic regression models were used to assess the association between node-positive status and LN size adjusting for age, BMI, tumor size, tumor grade, tumor subtype, and lymphovascular invasion. Results A strong likelihood of node-positive breast cancer was observed among obese women with fat-expanded lymph nodes (adjusted OR for the 4th vs. 1st quartile for contralateral LN size on MRI: 9.70; 95% CI 4.26, 23.50; p < 0.001). The receiver operating characteristic curve for size of fat-enlarged nodes in the contralateral axilla identified on breast MRI had an area under the curve of 0.72 for predicting axillary metastasis, and this increased to 0.77 when combined with patient and tumor characteristics. Conclusion Fat expansion of axillary lymph nodes was associated with a high likelihood of axillary metastases in obese women with invasive breast cancer independent of BMI and tumor characteristics.

PURPOSE: To determine whether intensifying the dose of adjuvant chemotherapy improves the outcome of women with primary breast cancer and 10 or more involved axillary nodes. PATIENTS AND METHODS: Patients (n = 150) were randomized to receive either four cycles of standard doxorubicin 60 mg/m2 plus cyclophosphamide 600 mg/m2 every 3 weeks (arm A) or four courses of intensified mitoxantrone 23 mg/m2 plus cyclophosphamide 600 mg/m2, with filgrastim 5 g/kg/d from days 2 to 15, every 3 weeks (arm B). Disease-free survival (DFS), distant disease-free survival (DDFS), and overall survival (OS) were determined using life-table estimates. RESULTS: There were no significant differences in DFS (P = .44), DDFS (P = .67), or OS (P = .99) between the two groups at 5 years; DDFS was 45% (arm A) versus 50% (arm B), and DFS was 41% versus 49%, respectively. Five-year survival was similar in both arms (61% v 60%, respectively). Failure to note an intergroup difference in outcome was unrelated to relative dose-intensity. Analysis of patients with 15 or more positive nodes revealed a significant difference in 5-year DDFS (19% v 49% in arm B; P = .01). Toxicity was generally mild in both groups, with no toxic death. The incidence of febrile neutropenia was low (0.3% v 3%). Alopecia was less frequent in arm B (P < .001). CONCLUSION: This randomized trial confirms the feasibility of administering mitoxantrone 23 mg/m2 with cyclophosphamide and filgrastim. Although there was no significant difference between conventional and intensified arms at 5 years, according to subgroup analysis, intensified treatment may decrease the risk of relapse in patients with 15 or more positive nodes compared with doxorubicin an cyclophosphamide.

516 Background: Evidence suggests that docetaxel is more effective than paclitaxel, and paclitaxel is more effective when given weekly than every 3 weeks in metastatic breast cancer (BC). Methods: Eligibility included axillary lymph node positive or high-risk (tumor at least 2 cm) node-negative BC. All patients received 4 cycles of AC (doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2) every 3 weeks, followed by either: (1) paclitaxel 175 mg/m2 every 3 weeks × 4 (P3), (2) paclitaxel 80 mg/m2 weekly × 12 (P1), (3) docetaxel 100 mg/m2 every 3 weeks × 4 (D3), or (4) docetaxel 35 mg/m2 weekly × 12 (D1). The primary comparisons included taxane (P vs. D) and schedule (every 3 weeks vs. weekly), and secondary comparisons included P3 vs. other arms. The trial had 86% power to detect a 17.5% decrease in disease-free survival (DFS) for either primary comparison, and 80% power to detect a 22% decrease for the secondary comparisons (2-sided nomimal 5% level tests corrected for multiple comparisons). Results: A total of 4,950 eligible patients were accrued. There was no difference in the primary comparisons afer 856 DFS events and 483 deaths after a median follow-up of 46.5 months at the 4th interim analysis ( www.sabcs.org , abstract 48). This is the final pre-specified analysis for the primary comparisons after 1,042 DFS events and 650 deaths (with 1,020 DFS events at this time, to be updated at the meeting). After a median followup of 60.2 months, there remains no significant difference in the hazard ratio (HR) for the taxane (1.02; p=0.73) or schedule (1.07; p=0.30) (as in the first analysis). In secondary comparisons of the standard arm (P3) with the other arms (HR > 1 favoring the experimental arms), the HRs were 1.30 (p = 0.003) for arm P1, 1.24 (p=0.02) for arm D3, and 1.09 (p=0.33) for arm D1. Analysis of interaction by hormone-receptor status will be presented. The incidence of worst grade toxicity (grade 3/4) was 24%/6% for arm P3, 24%/3% for arm P1, 21%/50% for arm D3, and 38%/6% for arm D1. Conclusions: There were no differences in DFS when comparing taxane or schedule overall. DFS was significantly improved in the weekly paclitaxel and every 3-week docetaxel arms compared with the every 3-week paclitaxel arm. [Table: see text]
