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.

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.

Chemoendocrine Therapy

Between 1978 and 1981, 463 evaluable postmenopausal patients 65 years of age or younger with operable breast cancer and metastases in axillary lymph nodes were entered in Ludwig Breast Cancer Study III (Ludwig III) and randomly allocated to receive chemoendocrine therapy with cyclophosphamide, methotrexate, 5-fluorouracil, low-dose continuous prednisone, and tamoxifen (CMFp + T) for 12 monthly cycles, or endocrine therapy alone with prednisone and tamoxifen (p + T) for 1 year, or no adjuvant treatment after mastectomy (observation). At 60 months' median follow-up, the 5-year disease-free survival (DFS) rates were 59% for CMFp + T, 41% for p + T, and 31% for observation (P less than .0001), and the 5-year overall survival (OS) rates were 71% for CMFp + T, 64% for p + T, and 59% for observation (P = .16; CMFp + T v observation, P = .07). A new quality of life-oriented endpoint was defined to assist in the selection of therapeutic approach after surgery for postmenopausal patients: the time without symptoms of disease and subjective toxic effects of treatment (TWiST). Despite the larger initial discount due to subjective toxicity with chemoendocrine therapy, by 5 years postmastectomy the net difference in average TWiST for treated patients compared with the observation group was positive and approximately equal for both adjuvant treatment programs. Adjuvant chemoendocrine therapy for postmenopausal women appears to be justified due to an emerging OS advantage and increasing TWiST gained for the treated patients.

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.

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]

Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant therapies on disease-free survival was explored. Statistical analysis included the chi-square, Wilcoxon–Mann–Whitney test, and Kaplan–Meier survival analysis. Results A total of 1080 patients were included in the study. A first group consisted of 328 patients in whom a single SLN was retrieved, and a second group consisted of 752 patients in whom two or more SLNs were retrieved. There was no relevant difference in median DFS (64.9 vs 41.4) for SLN = 1 vs SLN > 1 groups (HR 0.76, CI 95% 0.39–1.46; p = 0.38). A statistically significant difference in mDFS was showed only for HT-treated patients who were SLN = 1 if compared to SLN > 1 (100.6 months versus 35.3 months). Conclusions There is likely a relationship between the number of resected SNL and mDFS. Our results, however, showed no relevant difference in median DFS for SLN = 1 vs SLN > 1 group, except for a subset of the patients treated with hormone therapy.

Abstract Backgroud: Longer follow-up was necessary to testify the exact value of mastoscopic axillary lymph node dissection (MALND).Methods：From January 1, 2003 to December 31, 2005,1027 patients with operable breast cancer were randomly assigned to two groups: MALND and CALND. 996 eligible patients were enrolled. The end points are disease free survival and overall survival.Results：The final cohort of 996 patients was followed for an average of 184 months. The distribution of all events was fairly similar between two groups of patients. The incidence of local in-breast events did not differ in a significant manner between two cohorts. Similarly, the rate of distant metastases was not significantly different with 30.0% in MLND and 32.6% in CALND. And no significant difference was observed in other primary tumor between two groups (p=0.46). Patients who remain alive with no event comprise a total of 37.2% in MALND and 35.4% in CALND. Other primary cancers and deaths from other causes were distributed equally between two groups. The 15-year disease-free survival rates were41.1 percent for the MALND group and 39.6 percent for the CALND group (p=0.79). MALND was found to be not inferior for overall survival (P =0.54). The 15-year overall survival rates were 49.5 percentafter MALND and 51.2 percentafter CALND (p=0.86). Probability of overall survival was not significantly different between two groups.Conclusions：MALND does not increase unfavorable events, and also does not affect the long-term survival of patients. Therefore, MALND should be one of the preferred approaches for breast cancer surgery.

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.

The Impact

A prospective randomized trial to assess the impact of adding oophorectomy to adjuvant chemotherapy has been conducted in premenopausal patients with operable breast cancer and with metastases in four or more axillary lymph nodes. Following at least total mastectomy and axillary clearance, 327 evaluable patients were randomized to adjuvant oophorectomy followed by chemotherapy with cyclophosphamide (C), methotrexate (M), 5-fluorouracil (F), and prednisone (p) or to CMFp alone. At 48 months of median follow-up, no statistically significant differences between regimens in terms of disease-free survival or overall survival were demonstrated, even for patients with steroid hormone receptor-containing tumors. A high incidence of amenorrhea (89%) due to ovarian function suppression was observed for the group receiving CMFp alone. Supplementation of the adjuvant therapy regimen by surgical oophorectomy is rendered superfluous by this effect of cytotoxic treatment. The addition of oophorectomy to combination chemotherapy with CMFp cannot be recommended as adjuvant treatment for high-risk (four or more axillary lymph nodes involved) premenopausal patients with operable breast cancer.
