511 Background: Retrospective data suggest that patients (pts) with small HER2+ cancers have more than just minimal risk of disease recurrence. The APT trial was designed to address treatment for such pts. We have previously reported 3-yr disease-free survival (DFS) and here we provide an updated analysis with 7-yr DFS. Methods: APT is a single arm multicenter, phase II study of TH. Pts with HER2+ BC (IHC 3+ and/or FISH ratio > 2.0) with negative nodes (a single axillary lymph node micrometastasis was allowed) and tumor size < 3 cm were eligible. Pts received T (80 mg/m2) with H x 12 weekly (w), followed by H (weekly or q3w) x 39w. The primary endpoint was DFS. Recurrence Free Interval (RFI), Breast Cancer Specific Survival (BCSS), and overall survival (OS) were also analyzed. Intrinsic subtyping by PAM50 was performed on the nCounter Analysis system on archival tissue. Results: 410 pts were enrolled from September 2007 to September 2010 and 406 began protocol therapy. 67% had hormone-receptor (HR)+ tumors. Distribution by tumor size: 2% T1mi; 17% T1a; 30% T1b; 42% T1c, and 9% T2 ≤ 3 cm. 6 pts had a nodal micrometastasis. With a median follow-up of 6.5 yrs, there were 23 DFS events observed: 4 (1.0%) distant recurrences, 5 local/regional recurrences (1.2%), 6 new contralateral BC (1.5%), and 8 deaths without documented recurrence (2.0%). The 7-yr DFS was 93.3% (95% CI 90.4-96.2); 7-yr DFS for HR+ pts was 94.6% (95% CI 91.8-97.5) and for HR- pts was 90.7% (95% CI 84.6-97.2). 7-yr RFI was 97.5% (95% CI 95.9-99.1); 7-year BCSS is 98.6% (95% CI 97.0-100); and 7-yr OS was 95.0% (95% CI 92.4-97.7). Ongoing PAM50 testing (n = 227 pts) identified 142 (63%) HER2-enriched; 22 (10%) luminal A, 26 (11%) luminal B, and 20 (9%) basal-like; 17 samples had a poor quality assay. Additional testing and associations with clinical outcomes will be presented at the meeting. Conclusions: These data suggest that TH as adjuvant therapy for node-negative HER2+ BC is associated with few recurrences and only 4 distant recurrences with longer follow-up. Based on these data, if chemotherapy/trastuzumab is given to a pt with stage I HER2+ breast cancer, the TH regimen should be considered a standard treatment. Clinical trial information: NCT00542451.

Introduction Human epidermal growth factor receptor 2 (HER2) expression is considered an unfavourable prognostic factor in early breast cancer when the patients are not treated with HER2-targeted therapy. However, the long-term prognostic importance of HER2-expression in small (≤1 cm, stage pT1a-b), node-negative HER2+ breast cancer is still incompletely known. Methods A retrospective analysis was performed based on a prospectively collected database including patients with pT1 breast cancer operated at the Helsinki University Hospital, Finland, between March 2000 and April 2006. In this database, 44 patients with pT1a-bN0M0, HER2+ cancer, not treated with adjuvant anti-HER2-targeted therapy (the HER2+ group) and 291 pT1a-bN0M0, hormone receptor positive, HER2- negative cancers (the ER+/HER2- group) were identified and included in the study. Survival outcomes were analysed using the Kaplan-Meier method. Results The median follow-up time was 9.7 years after primary breast surgery. Ten-year distant disease-free survival (DDFS) was 84.0% in the HER2+ group and 98.2% in the ER+/HER2- group (p < 0.001). Ten-year overall survival was only 78.5% in the HER2+ group, but 91.7% in the ER+/HER2- group (p = 0.09). Conclusions Cancer HER2-status is strongly associated with unfavourable DDFS during the first decade of follow-up in patients with small (pT1a-bN0M0) breast cancer when adjuvant anti-HER2-targeted treatment is not administered.

Background: In node-negative HER2-overexpressed breast cancers, adjuvant paclitaxel plus trastuzumab treatment is a successful de-escalation approach with excellent survival outcomes. Methods: All patients with HER2+ breast cancer treated in our centers were retrospectively reviewed. Results: We analyzed 173 patients who were treated with adjuvant paclitaxel plus trastuzumab. The mean tumor size was 2.2 cm. There were eight invasive disease events or death: four distant recurrences (2.3%), three locoregional recurrences (1.7%) and one death without documented recurrence after a 52 month follow-up. The 3-year disease-free survival and recurrence-free interval rate was 96.6%. Conclusion: This real-life experience with adjuvant paclitaxel plus trastuzumab demonstrated few distant recurrences and is compatible with the APT trial findings.

Abstract Purpose 1. To systematically analyse studies comparing survival outcomes between axillary lymph-node dissection (ALND) and axilla observation (Obs), in women with low-risk, clinically node-negative breast cancer. 2. To consider results in the context of current axillary surgery de-escalation trials and studies. Methods 9 eligible studies were identified, 6 RCTs and 3 non-randomized studies (4236 women in total). Outcomes assessed: overall survival (OS) and disease-free survival (DFS). The logged (ln) hazard ratio (HR) was calculated and used as the statistic of interest. Data was grouped by follow-up. Results Meta-analyses found no significant difference in OS at 5, 10 and 25-years follow-up (5-year ln HR = 0.08, 95% CI − 0.09, 0.25, 10-year ln HR =  0.33, 95% CI − 0.07, 0.72, 25-year ln HR = 0.00, 95% CI − 0.18, 0.19). ALND caused improvement in DFS at 5-years follow-up (ln HR = 0.16, 95% CI 0.03, 0.29), this was not demonstrated at 10 and 25-years follow-up (10-year ln HR = 0.07, 95% CI − 0.09, 0.23, 25-year ln HR = − 0.03, 95% CI − 0.21, 0.16). Studies supporting ALND for DFS at 5-years follow-up had greater relative chemotherapy use in the ALND cohort. Conclusion ALND does not cause a significant improvement in OS in women with clinically node-negative breast cancer. ALND may improve DFS in the short term by tailoring a proportion of patients towards chemotherapy. Our evidence suggests that when the administration of systemic therapy is balanced between the two arms, axillary de-escalation studies will likely find no difference in OS or DFS.

Uncertainty exists around the need to include an anthracycline if taxane-based adjuvant chemotherapy is being used for human epidermal growth factor receptor-2 (HER2) negative and axillary lymph node negative (LNN) breast cancer. We identified all patients who were diagnosed with HER2-negative, LNN breast cancer treated with docetaxel-cyclophosphamide for four cycles (DC4) or an anthracycline-taxane (AT) regimen following surgical resection in Alberta from 2008 through 2012. We used propensity score methods to match each patient treated with AT to up to four patients treated with DC4 on potentially confounding clinicopathologic and treatment variables. We compared the 10-year invasive disease free survival (iDFS), breast cancer specific-survival (BCSS) and overall survival (OS) and assessed the effect of the type of adjuvant chemotherapy on these outcomes using Cox regression. Of the 726 eligible patients, 657 (90.5%) were treated with DC4 and 69 (9.5%) were treated with AT. Matching created a group of 202 women treated with DC4 and eliminated differences in clinicopathologic and treatment factors. There was no statistically significant difference for the treatment effects of matched DC4 patients compared to the AT patients on iDFS (75.7% vs. 76.8%, p = 0.75; hazard ratio (HR) = 1.05, 95% CI = 0.65 to 1.8), BCSS (88.1% vs. 87%, p = 0.8; HR = 0.91, 95% CI = 0.42 to 1.9), or OS (87.1% vs. 86.9%, p= 0.96; HR = 0.98, 95% CI = 0.46 to 2.1). Four cycles of DC as compared with an AT regimen yielded similar 10-year iDFS, BCSS and OS amongst patients with HER2-negative, LNN breast cancer.

PURPOSE To determine prospectively the prognostic significance of HER-2/neu oncogene amplification in the primary tumors of breast cancer patients. METHODS HER-2/neu amplification in tumor DNA was determined by the slot-blot technique in 1,056 patients with breast cancer (stage I to III) diagnosed between 1987 and 1990. Parameters such as estrogen receptor (ER) and progesterone receptor (PgR) levels, tumor size, axillary nodal involvement, tumor grade, and time to relapse were prospectively obtained. RESULTS HER-2/neu oncogene amplification, > or = 2, > or = 3, and > or = 5 copy number, was detected in 21%, 11%, and 7% of patients, respectively. In a test set of 529 patients, Cox multivariate analysis showed HER-2/neu copy number > or = 3 or > or = 5 was associated with shorter disease-free survival (DFS) duration. HER-2/neu copy number > or = 3 correlated significantly with pathologic stage of disease, number of axillary nodes with tumor, histologic type, and absence of ER and PgR. For all patients, after a median follow-up duration of 39 months, Kaplan-Meier univariate analysis indicated that tumor oncogene copy number > or = 3 correlated with shorter DFS in both node-negative and node-positive patients. In Cox multivariate analysis, HER-2/neu copy number > or = 3 was associated with shorter DFS, independent of nodal status, ER level, and tumor size. CONCLUSION Although the follow-up duration of this study is relatively short, we conclude that HER-2/neu amplification is an independent predictor of shorter DFS in both node-negative and node-positive patients.

PURPOSE To compare the outcome of African American (AA) and Caucasian (C) breast cancer patients who had equivalent disease extent and were similarly treated. PATIENTS AND METHODS We compared prognostic characteristics, treatment, and outcome of 1,037 C and 481 AA breast cancer patients treated with mastectomy between 1946 and 1987. The median follow-up duration was 15.6 years. RESULTS During the study period, there was a successive increase in the percent of patients who presented with early breast cancer. Between 1980 and 1987, 35.1% AA versus 47.6% C patients had < or = 2-cm tumors and 50.0% AA versus 61.9% C patients were node-negative, while between 1946 and 1959, 27.7% AA and 31.3% C had < or = 2-cm tumors and 41.5% AA versus 40.4% C patients were node-negative. The treatments were similar during the study period. The 20-year disease-free survival (DFS) rate of AA compared with C patients with node-negative < or = 2-cm, 2.1- to 4-cm, and greater than 4-cm tumors and of patients with one to three and > or = four positive nodes was not significantly different. Equal-size tumors had similar proportion of positive axillary nodes in AA compared with C patients. The DFS for AA patients compared with C patients was similar in the periods 1946 to 1959, 1960 to 1969, and 1970 to 1979, but was lower between 1980 and 1987 (P = .02). In multivariable analysis, race was not a significant variable. CONCLUSION In this large group of uniformly treated breast cancer patients, race was not an independent factor that influenced outcome. The racial differences seen between 1980 and 1987 are likely because of a larger percent of greater than 2-cm and node-positive tumors in AA patients. Education and access to early diagnosis should reduce or eliminate the racial differences seen.

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.

Peritumoral Vascular Invasion

10586 Background: Peritumoral vascular invasion (PVI) has been recently recognized as a significant prognostic indicator for women with operable breast cancer, yet the clinical relevance of the degree of PVI in patients with no or limited involvement of the axillary nodes is unknown. Methods: 2606 consecutive patients with pT1–3, pN0 (1586)-1a (1020), and M0, operated and counseled for medical therapy from 1/2000 to 12/2002 were prospectively classified according to the degree of PVI: absent (2017, 77.4%), focal (368, 14.1%), moderate (51, 2.0%) and extensive (170, 6.5%). The median follow-up was 3.8 years for disease-free survival (DFS) and 4.3 years for overall survival (OS). Results: Patients with extensive PVI were more likely be younger, to have larger tumors, high tumor grade, axillary positive nodes, high Ki-67 expression, and HER2/neu over-expression if compared with patients having less amount if PVI (p for trend, <.0001). Patients with diffuse PVI were prescribed significantly more frequently anthracycline containing chemotherapy and less endocrine therapy alone (p for trend, <.0001). In patients with node negative disease a statistically significant difference in DFS, risk of distant metastases and OS was observed at the multivariate analysis for diffuse PVI versus no PVI (Hazard Ratios: 2.11, 95% CI, 1.02 to 4.34, P<.0001 for DFS; 4.51, 95% CI, 1.96 to 10.4, P<.0001 for distant metastases; 3.55, 95% CI, 1.24 to 10.1, P=.02 for OS). Conclusions: Extensive peritumoral vascular invasion has a prognostic role in patients with axillary lymph node negative breast cancer. The extent of vascular invasion should be considered in the therapeutic algorithm in order to proper select targeted adjuvant treatment. 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.

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]
