Purpose: This retrospective analysis aimed to identify whether breast cancer patients receiving radiotherapy alone following a complete clinical remission (cCR) to neoadjuvant chemotherapy had a worse outcome than those treated with surgery. Patients and Methods: One hundred thirty-six patients who had achieved a cCR to neoadjuvant chemotherapy for early breast cancer were identified from a prospectively maintained database of 453 patients. Of these, 67 patients had undergone surgery as their primary locoregional therapy, and 69 patients had radiotherapy alone. Outcome was assessed in relation to local recurrence-free survival, disease-free survival, and overall survival. Results: Median follow-up was 63 months in the surgery group and 87 months in the no surgery group. Prognostic characteristics were well balanced between the two groups. For surgery and no surgery, respectively, there were no significant differences in disease-free survival or overall survival (5-year, 74% v 76%; 10-year, 60% v 70%, P = .9) between the two groups. There was a nonsignificant trend toward increased locoregional-only recurrence for the no surgery group (21% v 10% at 5 years; P = .09), but no long-term failures of local control. Patients in the no surgery group who also achieved an ultrasound complete remission had a 5-year local recurrence rate of only 8%. Conclusion: In patients achieving a cCR to neoadjuvant chemotherapy, radiotherapy alone achieve survival rates as good as with surgery, but with higher local recurrence rates. Ultrasound may identify a low recurrence rate subgroup for assessing no surgery in a prospective trial.

e11628 Background: Neoadjuvant chemotherapy is one of the standard treatment options for patients with locally advanced breast cancer for twenty five years. In this study, we evaluate results of neoadjuvant chemotherapy in breast cancer patients. Methods: We retrospectively analyzed 68 patients with locally advanced breast cancer. Anthracycline/taxane-based chemotherapy regimens were prescribed mostly for neoadjuvant chemotherapy. Before chemotherapy was given, patients were examined for distant metastasis by radiologic methods thereafter if patient had distant metastasis, they were excluded. Patients with breast cancer received neoadjuvant chemotherapy were analyzed according to age, menopausal status, type of surgery, response to the treatment, histopathological properties and survival. After 3 to 6 cycle of chemotherapy patients were reevaluated by clinically and radiologically for response. Surgery was performed for appropriate patient thereafter adjuvant locoregional and systemic chemotherapy were continued. Results: Median age was 47 (29–43) years. 17,6 % of them were younger than 35 years and 42,6 % were premenopausal. Median follow-up time was 19 month. After 3 to 6 cycle of neoadjuvant chemotherapy 64 of patients responded to therapy (94,1 %). Breast conserving surgery was performed for 15,6 % patients. In histopathologic analysis most of patients were invasive ductal carcinoma and there was lymph node invasion for 84,9 %. Estrogen and progesterone receptor status were negative for 18,6 % of patients and cerbB2 was positive for 14,8 % of patients. Median disease free survival time was 44 month (SE: 9; 95% CI: 25–62) but median overall survival time could not be reached. Three years disease free survival rate and overall survival rate were 55,3% and 90,1% respectively. According to Cox regression analyses; we did not find any demographic and pathologic characteristic of breast cancer that is related to prognosis. Conclusions: In recent years neoadjuvant chemotherapy in breast cancer is increasingly being used for early stage disease. Further study will be facilitated establishment of guidelines for preselecting patients for neoadjuvant chemotherapy and will provide beneficial effect on treatment option and survival.

Purpose The purpose was to assess whether patients with clinical multifocal or multicentric (MFMC) breast cancer determined by mammogram, ultrasound, or physical examination have inferior outcome compared with patients with clinical unicentric lesions. Patients and Methods We retrospectively analyzed 706 consecutive patients with stages I-III breast cancer treated at the M.D. Anderson Cancer Center (Houston, TX) from 1976 to 2003 who received neoadjuvant anthracycline-based chemotherapy followed by breast conservation therapy (BCT), mastectomy alone, or mastectomy plus postmastectomy radiation therapy. Results The mean follow-up was 66 months. At presentation, 97 of 706 patients had clinically MFMC disease (13.7%). The 5-year rate of locoregional failure was 10% for unicentric disease compared with 7% for MFMC disease (P = .78). Subset analyses of patients by treatment groups confirmed no statistical difference in locoregional control regardless of the type of locoregional treatment. Among patients with multifocal disease treated with BCT, there were no in-breast recurrences and one supraclavicular recurrence. Five-year disease-free survival and overall survival was equivalent between patients with MFMC and unicentric breast cancers. Conclusion Patients with clinical MFMC breast cancer at the time of diagnosis treated with neoadjuvant chemotherapy followed by locoregional therapy have similar 5-year rates of locoregional control, disease-free survival, and overall survival as those with unicentric disease. Clinically detected MFMC disease did not predict for inferior outcome.

Aims and background Sixty-three patients with local-regionally advanced breast cancer were treated with neoadjuvant chemotherapy consisting of docetaxel (Taxotere), epirubicin, and 5-fluorouracil (TEF). Methods and study design Preoperatively, patients received four cycles of Taxotere (80 mg/m2), epirubicin (60 mg/m2), and 5-fluorouracil (500 mg/m2), repeated every 21 days. Following completion of four cycles of chemotherapy, appropriate surgery was performed. After the surgery, patients received one cycle of the TEF chemotherapy regimen; following chemotherapy, radiotherapy was applied, and at the end two more cycles of TEF chemotherapy regimen were given. Results Sixty-three patients with locally advanced breast cancer were treated. Three patients were excluded from the study before the evaluation of response. Median age of the patients was 50 years (range, 25–77). Twenty-seven and 33 patients were premenopausal and postmenopausal, respectively. Thirty-nine patients were in stage IIIA and 21 in stage IIIB. Complete and partial responses were observed in 15 (25%) and 42 (70%) of the patients following four cycles of preoperative TEF chemotherapy regimen, respectively. Overall response was 95%, and primary lesion progressed only in 3 (5%) patients. The mean disease-free survival was 15.9 ± 6.8 (range, 3.5–28) months and the mean overall survival was 18.6 ± 7.2 (range, 5–30) months. The most frequent side effects were nausea-vomiting, mucositis, alopecia and leukopenia. Conclusions TEF therapy is a treatment with a high overall response rate and toxicities similar to other taxotere combinations. A longer follow-up of patients is necessary for the determination of disease-free survival and overall survival.

Abstract Purpose The extended role of breast-conserving surgery (BCS) in the neoadjuvant setting may raise concerns on the oncologic safety of BCS compared to mastectomy. This study compared long-term outcomes after neoadjuvant chemotherapy (NAC) between patients treated with BCS and mastectomy. Methods All breast cancer patients treated with NAC from 2008 until 2017 at the Amphia Hospital (the Netherlands) were included. Disease-free and overall survival were compared between BCS and mastectomy with survival functions. Multivariable Cox proportional hazard regression was performed to determine prognostic variables for disease-free survival. Results 561 of 612 patients treated with NAC were eligible: 362 (64.5%) with BCS and 199 (35.5%) with mastectomy. Median follow-up was 6.8 years (0.9–11.9). Mastectomy patients had larger tumours and more frequently node-positive or lobular cancer. Unadjusted five-year disease-free survival was 90.9% for BCS versus 82.9% for mastectomy (p = .004). Unadjusted five-year overall survival was 95.3% and 85.9% (p < .001), respectively. In multivariable analysis, clinical T4 (cT4) (HR 3.336, 95% CI 1.214–9.165, p = .019) and triple negative disease (HR 5.946, 95% CI 2.703–13.081, p < .001) were negative predictors and pathologic complete response of the breast (HR 0.467, 95% CI 0.238–0.918, p = .027) and axilla (HR 0.332, 95% CI 0.193–0.572, p = .001) were positive predictors for disease-free survival. Mastectomy versus BCS was not a significant predictor for disease-free survival when adjusted for the former variables (unadjusted HR 2.13 (95%CI: 1.4–3.24), adjusted HR 1.31 (95%CI: 0.81–2.13)). In the BCS group, disease-free and overall survival did not differ significantly between cT1, cT2 or cT3 tumours. Conclusion BCS does not impair disease-free and overall survival in patients treated with NAC. Tumour biology and treatment response are significant prognostic indicators.

Aim: Adequate lymph node evaluation is recommended in patients with malignant tumors. However, the role of negative lymph nodes (NLNs) remains unclear in breast cancer (BC), especially in patients who have received neoadjuvant chemotherapy and mastectomy. Materials & methods: A total of 435 patients were included in the analysis. On multivariate analysis, NLN count was an independent predictor of 5 year disease-free survival and 5 year overall survival. Results: Patients with NLN count <10 showed significantly worse 5 year disease-free survival than those with NLN count ≥10 (34.8 and 78.2%; p = 0.000); the corresponding 5 year overall survival rates were also significantly different (52.0 and 82.7%; p = 0.000). Conclusion: This is the first study that confirms the relationship between NLN count and prognosis of patients in the setting of neoadjuvant chemotherapy and mastectomy. More NLNs imply better prognosis.

Background: Genetic variations in oxidative stress-related genes may alter the coded protein level and impact the pathogenesis of breast cancer. Methods: The current study investigated the associations of functional single nucleotide polymorphisms in the NFE2L2, HMOX1, P21, TXNRD2, and ATF3 genes with the early-stage breast cancer clinicopathological characteristics and disease-free survival, metastasis-free survival, and overall survival. A total of 202 Eastern European (Lithuanian) women with primary I–II stage breast cancer were involved. Genotyping of the single nucleotide polymorphisms was performed using TaqMan single nucleotide polymorphisms genotyping assays. Results: The CA+AA genotypes of P21 rs1801270 were significantly less frequent in patients with lymph node metastasis and larger tumor size ( P=0.041 and P=0.022, respectively). The TT genotype in ATF3 rs3125289 had significantly lower risk of estrogen receptor (ER), progesterone receptor (PR) negative, and human epidermal growth factor receptor 2 (HER2) positive status ( P=0.023, P=0.046, and P=0.040, respectively). In both, univariate and multivariate Cox analysis, TXNRD2 rs1139793 GG genotype vs. GA+AA was a negative prognostic factor for disease-free survival (multivariate hazard ratio (HR) 2.248; P=0.025) and overall survival (multivariate HR 2.248; P=0.029). The ATF3 rs11119982 CC genotype in the genotype model was a negative prognostic factor for disease-free survival (multivariate HR 5.878; P=0.006), metastasis-free survival (multivariate HR 4.759; P=0.018), and overall survival (multivariate HR 3.280; P=0.048). Conclusion: Our findings suggest that P21 rs1801270 is associated with lymph node metastasis and larger tumor size, and ATF3 rs3125289 is associated with ER, PR, and HER2 status. Two potential, novel, early-stage breast cancer survival biomarkers, TXNRD2 rs1139793 and ATF3 rs11119982, were detected. Further investigations are needed to confirm the results of the current study.

Background: Triple-negative breast cancer (TNBC) is an aggressive disease. Nomograms can predict prognosis of patients with TNBC. Methods: A total of 745 eligible TNBC patients were recruited and randomly divided into training and validation groups. Endpoints were disease-free survival and overall survival. Concordance index, area under the curve and calibration curves were used to analyze the predictive accuracy and discriminative ability of nomograms. Results: Based on the training cohort, neutrophil-to-lymphocyte ratio, positive lymph nodes, tumor size and tumor-infiltrating lymphocytes were used to construct a nomogram for disease-free survival. In addition, age was added to the overall survival nomogram. Conclusion: The current study developed and validated well-calibrated nomograms for predicting disease-free survival and overall survival in patients with TNBC.
