Background: Patients with supraclavicular metastases at diagnosis of breast cancer were classified between 1987 and 2002 as having stage M1 breast cancer according to the tumor-node-metastasis (TNM) system. The 2003 edition of the TNM staging guidelines has classified such patients as having stage IIIC disease. To determine relative prognosis, we compared long-term survival in a population-based cohort of patients with isolated supraclavicular metastases (nodal-M1) to outcomes of patients with stage IIIB or M1 (other) disease at presentation. Materials and Methods: Among patients with breast cancer and known tumor stage referred to the British Columbia Cancer Agency from 1976 to 1985, 336 IIIB, 233 M1, and 51 nodal-M1 patients were identified. Actuarial overall and breast cancer–specific survival rates were determined to 20 years. Results: Overall survival at 20 years was 13.2% for nodal-M1 cases (95% confidence interval [CI], 5% to 26%), 9.4% for IIIB cases (95% CI, 6% to 14%), and 1.3% for M1 (other) cases (95% CI, 0.4% to 3.5%; log-rank P < .0005). Overall survival was similar between nodal-M1 and IIIB cases (P = .27). Breast cancer–specific survival at 20 years was 24.1% for nodal-M1 cases (95% CI, 13% to 37%), 30.2% for IIIB cases (95% CI, 23% to 38%), and 3.9% for M1 (other) cases (95% CI, 2% to 8%; log-rank P < .0005). Breast cancer–specific survival was significantly different for nodal-M1 cases compared with either IIIB or M1 (other) cases (P = .008 for both). Conclusion: Patients with supraclavicular metastases at diagnosis have significantly better outcomes than patients with M1 (other) disease and overall survival similar to patients with IIIB disease. Reclassification as stage IIIC is appropriate for patients with breast cancer who present with supraclavicular nodal metastases alone.

Esr1 Gene

10501 Background: Estrogen receptor alpha (ERα) expression is a prognostic parameter in breast cancer and predicts response to endocrine therapy. One of the factors important for protein expression is amplification of its encoding gene ESR1. We have investigated the value of ESR1 amplification in predicting the long-term clinical outcome in tamoxifen-treated postmenopausal women with endocrine-responsive breast cancer. Methods: 394 patients who had been randomized into the tamoxifen-only arm of the prospectively designed endocrine ABCSG-06 trial and in whom FFPE tumor tissue was available were included in this analysis. Immunohistochemical ERα expression was evaluated both locally and centrally using the Allred score, while ESR1 gene amplification status was evaluated by FISH analysis using the ESR1/CEN6 ratio. Results: ESR1 copy number gains were detected in 187 of 394 (47%) tumor specimen and was associated with favorable clinical outcome. At a median follow-up of 10 years, women with intratumoral ESR1 copy number gains had a significantly longer distant recurrence-free survival (adjusted HR for relapse 0.48; 95% CI 0.28-0.83; p=0.009) and breast cancer-specific survival (adjusted HR for death 0.46; CI 0.46-0.71; p=0.006) when compared to women with normal ESR1 copy numbers. Immunohistochemical ERα protein expression, evaluated by Allred score, was significantly correlated with ESR1 copy number alterations (p<0.0001; Chi-Square test), but did itself not allow to discriminate between patients with poor and good prognosis. Conclusions: ESR1 amplification status is an independent and powerful predictor for long-term distant recurrence-free and breast cancer-specific survival in postmenopausal women with endocrine-responsive early-stage breast cancer who received 5 years of tamoxifen.

Long Term Follow Up

Purpose To determine whether there is a benefit to adjuvant radiation therapy after breast-conserving surgery and tamoxifen in women age ≥ 70 years with early-stage breast cancer. Patients and Methods Between July 1994 and February 1999, 636 women (age ≥ 70 years) who had clinical stage I (T1N0M0 according to TNM classification) estrogen receptor (ER) –positive breast carcinoma treated by lumpectomy were randomly assigned to receive tamoxifen plus radiation therapy (TamRT; 317 women) or tamoxifen alone (Tam; 319 women). Primary end points were time to local or regional recurrence, frequency of mastectomy, breast cancer–specific survival, time to distant metastasis, and overall survival (OS). Results Median follow-up for treated patients is now 12.6 years. At 10 years, 98% of patients receiving TamRT (95% CI, 96% to 99%) compared with 90% of those receiving Tam (95% CI, 85% to 93%) were free from local and regional recurrences. There were no significant differences in time to mastectomy, time to distant metastasis, breast cancer–specific survival, or OS between the two groups. Ten-year OS was 67% (95% CI, 62% to 72%) and 66% (95% CI, 61% to 71%) in the TamRT and Tam groups, respectively. Conclusion With long-term follow-up, the previously observed small improvement in locoregional recurrence with the addition of radiation therapy remains. However, this does not translate into an advantage in OS, distant disease-free survival, or breast preservation. Depending on the value placed on local recurrence, Tam remains a reasonable option for women age ≥ 70 years with ER-positive early-stage breast cancer.

Purpose The aim of this nationwide, register-based cohort study was to determine whether women treated for depression before primary early-stage breast cancer are at increased risk for receiving treatment that is not in accordance with national guidelines and for poorer survival. Material and Methods We identified 45,325 women with early breast cancer diagnosed in Denmark from 1998 to 2011. Of these, 744 women (2%) had had a previous hospital contact (as an inpatient or outpatient) for depression and another 6,068 (13%) had been treated with antidepressants. Associations between previous treatment of depression and risk of receiving nonguideline treatment of breast cancer were assessed in multivariable logistic regression analyses. We compared the overall survival, breast cancer–specific survival, and risk of death by suicide of women who were and were not treated for depression before breast cancer in multivariable Cox regression analyses. Results Tumor stage did not indicate a delay in diagnosis of breast cancer in women previously treated for depression; however, those given antidepressants before breast cancer had a significantly increased risk of receiving nonguideline treatment (odds ratio, 1.14; 95% CI, 1.03 to 1.27) and significantly worse overall survival (hazard ratio, 1.21; 95% CI, 1.14 to 1.28) and breast cancer–specific survival (hazard ratio, 1.11; 95% CI, 1.03 to 1.20). Increased but nonsignificant estimated risks were also found for women with previous hospital contacts for depression. In subgroup analyses, the association of depression with poor survival was particularly strong among women who did not receive the indicated adjuvant systemic therapy. Conclusion Women previously treated for depression constitute a large subgroup of patients with breast cancer who are at risk for receiving nonguideline breast cancer treatment, which probably contributes to poorer overall and breast cancer–specific survival.

Cancer Specific Survival

e12600 Background: Currently the treatment paradigm for locally advanced breast cancer (LABC) is multimodality therapy with neoadjuvant systematic treatment, surgery and postoperative radiation therapy (RT). However, with improving outcomes from systematic therapy, the survival rates remain unpromising, which leads to the investigation of the concept of preoperative RT in LABC due to the potential advantages including a possible tumor downstaging and better cosmetic outcomes. We evaluated the overall survival (OS) and breast cancer specific survival (BCSS) of preoperative versus postoperative RT in LABC patients. Methods: Patients diagnosed with non-inflammatory LABC (defined as T3 N1, T4 N0, any N2 or N3, and M0) who received RT before or after surgery between 2010 and 2015 were identified using the SEER database. OS and BCSS were analyzed using Kaplan-Meier method and multivariate Cox proportional hazards model. Results: Among 19249 patients with LABC, 140 (0.7%) received preoperative RT and 19109 (99.3%) received postoperative RT. Overall, 5-year survival and BCSS are 59% and 63% in the preoperative RT group while 77% and 80% in the postoperative RT group. In all patients, treatment with preoperative RT was significantly associated with poor OS (HR 1.82, 95%CI 1.25 to 2.45, P < 0.001) and BCSS (HR 2.00, 95%CI 1.46 to 2.73, P < 0.001) after adjustment for other clinically relevant factors. However, there were no significant difference in terms of both OS and BCSS in ER+ (OS: HR 1.44, 95%CI 0.91 to 2.27, P = 0.12; BCSS: HR 1.55, 95%CI 0.94 to 2.54, P = 0.08) and HER2+ patients (OS: HR 1.33, 95%CI 0.55 to 3.22, P = 0.53; BCSS: HR 1.64, 95%CI 0.67 to 3.97, P = 0.28). Conclusions: Overall, preoperative RT in LABC may reduce overall survival and breast cancer specific survival. However, OS and BCSS were independent of radiation sequence for ER+ and HER2+ patients. This finding warrants further exploration of potential mechanisms of the disparity and the definitive role of preoperative RT in the multimodality therapy of LABC patients.

Purpose With mammographic screening, the frequency of diagnosis of stage T1a,bN0M0 breast cancer has increased. Prognosis after locoregional therapy and benefit from adjuvant systemic therapy are poorly defined. We reviewed T1a,bN0M0 breast cancer cases registered in the Surveillance, Epidemiology, and End Results (SEER) Program to investigate the impact of prognostic factors on breast cancer–specific (BCSM) and non–breast cancer–related mortality. Methods We identified T1a,bN0M0 breast cancer cases registered in the SEER Program from 1988 to 2001, and used the Kaplan-Meier product limit method to describe overall survival (OS). We estimated the probabilities of death resulting from breast cancer and from other causes, and analyzed associations of patient and tumor characteristics with OS, BCSM, and non–breast cancer–related mortality using the log-rank test, Cox proportional hazards models, and a competing-risk model. We constructed nomograms to assist physicians in adjuvant therapy decision making. Results We identified 51,246 T1a,bN0M0 cases. Median follow-up was 64 months (range, 1 to 167 months). Median age at diagnosis was 65 years (range, 20 to 101 years). Ten-year probabilities of all-cause mortality and BCSM were 24% and 4%, respectively. Characteristics associated with increased probability of BCSM included age younger than 50 years at diagnosis, high tumor grade, estrogen receptor–negative status, progesterone receptor–negative status, and fewer than six nodes removed at axillary dissection. The constructed nomograms allow a comparison of predicted breast cancer–specific survival and non-breast cancer–specific survival in individual patients. Conclusion Overall, the prognosis of patients with T1a,bN0M0 breast cancer is excellent. However, subgroups of patients who are at higher risk of BCSM and who should be considered for adjuvant systemic therapy can be identified.

Abstract Objective Demands for genetic counseling with BRCA1/2 examination have markedly increased. Accordingly, the incidence of uninformative results on BRCA1/2 mutation status has also increased. Because most patients examined for BRCA1/2 mutation have a high risk of hereditary breast and/or ovarian cancer, many patients suffer psychological distress even when the BRCA1/2 result is negative. We compared oncological outcomes between BRCA1/2-negative breast cancer with high risk of hereditary breast and/or ovarian cancer and sporadic breast cancer without risk of hereditary breast and/or ovarian cancer. Methods The criteria for high risk for hereditary breast and/or ovarian cancer were defined as family history of breast and/or ovarian cancer in first- or second-degree relative, early onset breast cancer at &lt;35 years old and bilateral breast cancer. Patients were matched maximally 1:3 into those who identified as negative for BRCA1/2 mutation with risk of hereditary breast and/or ovarian cancer (study group) and those who were not examined for BRCA1/2 mutation without risk for hereditary breast and/or ovarian cancer (control group). Matched variables were pathologic stage, estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 status. Results All matching variables were successfully matched. Median follow-up duration was 57.8 months. There was no significant difference between the groups in disease-free survival (log-rank P = 0.197); however, the study group showed significantly better overall survival and breast cancer-specific survival (both P &lt; 0.0001). We conducted subgroup analysis in the middle-aged group (36–54) and showed no significant difference for disease-free survival (P = 0.072) but significantly better overall survival and breast cancer-specific survival in the study group (P = 0.002 and P &lt; 0.0001). Conclusions BRCA1/2-negative breast cancer patients who had hereditary breast and/or ovarian cancer risk factors showed similar disease-free survival and better overall survival and breast cancer-specific survival compared with those with sporadic breast cancer without hereditary breast and/or ovarian cancer risk factors.

Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a major regulator of the oxidative stress response and it is negatively regulated by Kelch-like ECH-associated protein 1 (Keap1). The Keap1–Nrf2 axis has a fundamental role in carcinogenesis. In previous studies, the widely used diabetes drug metformin has appeared to have a critical role in the regulation of Nrf2 function. In this study, we assessed the expression of Nrf2 and Keap1 immunohistochemically in 157 patients with type 2 diabetes who underwent breast cancer surgery with curative intent. In total, 78 (49.7%) of these patients were taking metformin alone or combined with other oral anti-diabetic medication at the time of breast cancer diagnosis. We found that high-level cytoplasmic Nrf2 expression predicted dismal overall survival and breast cancer–specific survival, but only in the patients who were not taking metformin at the time of diagnosis. Similarly, low-level nuclear Keap1 expression had an adverse prognostic value in terms of overall survival and breast cancer–specific survival in patients without metformin. On the other hand, high-level nuclear Keap1 expression was associated with prolonged overall survival and breast cancer–specific survival. The results may be explained in terms of non-functioning or displaced Keap1, although more mechanistic pre-clinical and prospective clinical studies are warranted.
