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.

PURPOSE To compare two adjuvant combination chemotherapies, cyclophosphamide, methotrexate, and fluorouracil (CMF) and chlorambucil, methotrexate, and fluorouracil (LMF), for patients who had undergone potentially curative surgery for unilateral breast cancer, in terms of relapse, survival, and toxicity. PATIENTS AND METHODS Selection criteria was as follows: stage pT1-3a, N+ or N-, M0, less than 72 years of age. Eligible patients were randomized to receive either CMF (cyclophosphamide 100 mg/m2 orally on days 1 to 14, methotrexate 40 mg/m2 intravenously (I.V.) on days 1 and 8, fluorouracil 600 mg/m2 I.V. on days 1 and 8) or LMF (Leukeran [Wellcome A.G., Bern, Switzerland] 5 mg/m2 orally on days 1 to 14 with the some I.V. cytostatic drugs). Follow-up examinations were performed every 3 months during the first 3 years after mastectomy, and every 6 months thereafter. RESULTS A total of 246 patients were randomized, of whom 232 who were fully eligible and contribute to the analyses presented here. No statistically significant difference in favor of adjuvant CMF over LMF emerges after a median follow-up duration of 11.2 years, for either overall survival (P = .15) or disease-free survival (P = .14). A consistent trend suggestive of a possible relative benefit associated with CMF should be pointed out. However, CMF presents a significantly worse toxicity profile as concerns hematologic parameters as well as alopecia, nausea, and vomiting. CONCLUSION This prospective trial has not identified a statistically significant difference in disease-free survival or overall survival between the two adjuvant regimens LMF and CMF. Although a trend in favor of CMF has been observed in premenopausal patients, this has to be weighted against its definitely more pronounced toxicity profile.

Objectives: To analyze axillary lymph node involvement (ALNI) rate and survival for mucinous (MC) and tubular (TC) breast carcinomas considered being of very good prognosis and for which an axillary surgical exploration could be questioned. Methods: Our multicentric cohort consisted of 21,135 patients with clinically node-negative invasive breast cancer, without neoadjuvant therapy, between 1999 and 2013 in 10 French centers. ALNI rate and survival were analyzed according to patient and tumor characteristics. Results: Our cohort consisted of 672 TC and 245 MC. Patients were older and tumor size greater for MC and pathologic factors were more pejorative. The rate of mastectomies and adjuvant chemotherapy was higher in the MC group. Axillary lymph node status was determined by SLNB alone in 71.2% of patients. ALNI rates were 17.9% and 18% for TC and MC, respectively. ALNI rate was lesser for MC (OR 0.503, p = 0.024) and greater in case of lympho-vascular invasion (OR 5.0, p < 0.0001) and for tumors >10 mm (OR 2.17, p = 0.042). Median follow-up was 58 months. The 5- and 7-year overall survival rates were 97.1% and 95% for TC, respectively; 92.3% and 91.2% for MC ( p = 0.043); 5- and 7-year disease-free survival rates were 97.9% and 97.2% versus 95.2 and 93.6% ( p = 0.041). Lympho-vascular invasion was the only predictive factor for overall survival (hazard ratio [HR] = 2.70)’ grade 2 (HR = 10) and HR-negative (HR = 4.9) were the two predictive factors for disease-free survival. Conclusion: This study confirms the need for an axillary exploration for these tumors even for a tumor size <10 mm and a favorable prognosis.

CA 15–3 has been most widely used as a serum tumor marker in follow-up and detection of breast cancer recurrence. In this study we have specifically focused upon the prognostic implications and utility of preoperative CA 15–3 levels. We have identified on our database 414 patients with breast cancer in whom serial levels of the serum tumor marker CA 15–3 had been determined at diagnosis and follow-up. We have analyzed the follow-up and clinical outcomes in these patients and from this data we have assessed the potential of CA 15–3 as a predictor of five-year overall and disease-free survival. Our results show that an initially elevated CA 15–3 level is associated with a very poor prognosis in both early and late stage disease. Elevated pre-biopsy CA 15–3 levels are associated with 14% five-year disease-free survival rates and 17% overall survival rates at five years. In contrast, normal CA 15–3 levels are associated with 47% five-year disease-free survival rates and 54% overall survival rates at five years (p<0.01). Comparison of five-year survival rates between patients with elevated and normal CA 15–3 levels in early breast cancer (stage I and II) also showed significant differences, with survival being 41% and 75%, respectively (p<0.01).

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

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]

513 Background: An Early Breast Cancer Trialists' Collaborative Group (EBCTCG) meta-analysis indicates that adjuvant bisphosphonates increase time to bone recurrence and survival in postmenopausal breast cancer patients, but results of individual trials have been inconclusive. Retrospective analyses of AZURE, a trial of adjuvant zoledronic acid, showed MAF (a transcription factor of the AP-1 family) amplification status predicted bisphosphonate benefit independently of menopause for invasive disease-free survival (IDFS) and overall survival (OS). Validation of MAF amplification status as a potential companion diagnostic for adjuvant bisphosphonates was confirmed using NSABP-B34 specimens. Methods: The randomized, placebo-controlled NSABP B-34 study of women with stage 1-3 breast cancer were assigned to adjuvant systemic therapy plus oral clodronate 1600 mg daily or placebo for 3 years. The primary endpoint was disease-free survival (DFS) with overall survival (OS) as a secondary outcome. MAF amplification was assessed by fluorescence in-situ hybridization on anonymized sections of breast tumor tissue in all patients with tumor samples and performed in a laboratory blind to treatment assignment. Protocol and analysis plans were pre-specified. Disease outcomes were analysed using intention to treat principles. Results: 2496 B-34 patients contributed tumor samples (from 2001-2004), of whom 1883 (75%) were evaluable (947 placebo and 936 clodronate). 1515 (80%) tumors were MAF negative (766 placebo and 749 clodronate) and 368 were MAF positive. At median follow-up of 108 months, MAF was prognostic for DFS, OS and bone-metastasis-free survival in the control group (MAF-positive vs MAF-negative: HRDFS=1·39, 95%CI 1·01-1·92; p=0.045; HROS=1·59, 95%CI 1·08-2·33; p=0.018; HRBM=2·03, 95%CI 1·13-3·68; p=0.016). In patients with MAF-negative tumors, clodronate gave higher DFS and OS than controls at 60 months (HRDFS=0·70, 95%CI 0·51-0·94; p=0.020 and HROS=0·59, 95%CI 0·37-0·93; p=0.024), the latter maintained through follow-up (HROS=0·74, 95%CI 0·54-1.00; p=0.047), but not in patients with MAF-positive tumors - consistent with previous AZURE results. Conclusions: MAF benefit prediction from adjuvant bisphosphonates was confirmed using specimens from 2 randomized clinical trials (AZURE and NSABP-B-34) conducted and analyzed in similar manner using the same validated tests and clinical endpoints. These results are evidence towards introducing MAF testing into clinical practice.

e12566 Background: This study discusses the analysis of the prospectively collected material on pregnant patients treated for breast cancer at the Department of Breast Cancer and Reconstructive Surgery of the Maria Skłodowska-Curie National Oncology Institute - National Research Institute (until 2020: Oncology Center - Institute) in Warsaw, in the years 1995 - 2020. 84 patients were included into the final analysis and 72 children were assessed simultaneously. Methods: The paper summarizes information on the diagnosis and treatment of breast cancer during pregnancy, the course of pregnancy and childbirth and the birth parameters of children i.e. weight, length and Apgar score, as well as the dependencies between them, mainly the impact of some breast cancer, diagnosis and treatment process features on the newborns. The patietnt’s survavial - DFS ( disease free survival) and OS ( overall survival) - was also analyzed. The course of breast cancer diagnosis and treatment data were obtained from the patients’ medical documentation (medical records) and from information provided by the mothers during follow-up visits and read in the children's health books. In order to answer the research questions, statistical analyzes were conducted using the IBM SPSS Statistics 26 package. Results: In the analyzed period, the disease recurrence was recognized in 34 (40.5%) patients, and 24 (28.6%) patients died. The median disease-free survival (DFS) was 12.3 years (147.5 months), and the median overall survival (OS) was not reached during the follow-up period. The estimated 5-year survival rates for DFS and OS were 57.9% and 74.5% respectively, and for 10-year survival - 51.4% and 64.5%. The study showed a statistically significant relationship between the baseline clinical advancement and DFS. It has been also analyzed how the diagnosis, treatment and method of pregnancy termination changed in two time periods (1995-2012 and 2013-2020). There were no statistically significant differences in survival - both DFS and OS - between the group of patients treated before and after 2012. In the assessment of the impact of some factors on the birth children parameters (weight and length), statistically significant results were obtained for: pregnancy advancement at diagnosis, breast cancer stage at diagnosis, pregnancy advancement at the start of chemotherapy, the chemotherapy regimen (classic or dose-dense), the number of cycles of chemotherapy given during pregnancy, and the number of drugs used in supportive treatment. Conclusions: The entire analysis has become not only an insightful characteristic of the studied group, but also these results may be important in everyday clinical practice and may help to optimize the management of an extremely complex and difficult situation, which is the coexistence of pregnancy with a malignant disease that threatens the mother’s life.

Objective: To analyse outcomes of breast conservation surgery and to identify the factors that could have affected the outcomes. Method: The retrospectively study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data of breast conservation surgery cases done between January 2011 and October 2014 in order to cover up for the 5-year follow-up of the last enrolled patient. Data, obtained through the institutional information and database system, included disease-recurrence, 5-year disease-free survival and overall survival. Data was statistically analysed using SPSS 20. Results: Of the 553 cases, 417(75%) had no loco-regional recurrence or distant metastasis, while 136(25%) had some form of loco-regional, distant or contralateral metastasis at 5-year follow-up. In patients who had recurrence or metastasis, only progesterone receptor status, nodal status and mode of treatment showed significant association (p<0.05). Mortality at 5-year follow-up was 77(14%). Amongst the patients who died, only progesterone receptor status and nodal status had significant association (p<0.05). Five-year overall survival for the cohort was 476(86%), whereas 5-year disease-free survival was 409(74%). Conclusion: Breast conservation surgery was found to have favourable outcomes, while progesterone status, nodal involvement and mode of treatment significantly affected the outcome.
