117 Background: Neratinib is an irreversible pan-HER tyrosine kinase inhibitor with clinical efficacy in trastuzumab pre-treated HER2-positive (HER2+) metastatic breast cancer (BC). ExteNET is an ongoing multicenter randomized placebo-controlled phase III trial evaluating the efficacy and safety of a 1-year course of neratinib in patients with early-stage HER2+ BC after trastuzumab-based adjuvant therapy (clinicaltrials.gov: NCT00878709). Methods: Women with locally-confirmed early-stage HER2+ BC were randomly assigned to oral neratinib 240mg/day or matching placebo for 1 year. Archived diagnostic tumor samples were submitted for HER2 gene amplification testing at a central laboratory. Primary endpoint: invasive disease-free survival (iDFS). Secondary endpoints: DFS including ductal carcinoma in situ (DFS+DCIS); distant disease-free survival (DDFS); time to distant recurrence (TDR). Stratified Cox proportional-hazards models were used to estimate hazard ratios (HR) for the ITT and amended ITT (aITT) populations; unstratified models were used for the centrally confirmed HER2 population. Treatment groups were compared using 2-sided log-rank tests. Results: The ITT population included 2840 patients (neratinib, N=1420; placebo, N=1420). The higher-risk aITT population (i.e. node-positive disease and randomized ≤1 year of completing prior trastuzumab) included 1873 patients (neratinib, N=938; placebo, N=935). Of the tumor samples analyzed, 1463 (86%) were centrally confirmed (neratinib, N=741; placebo, N=722). Conclusions: Neratinib significantly improves iDFS in trastuzumab-treated early-stage HER2+ BC patients. An enhanced treatment effect is observed with neratinib in women with centrally confirmed HER2+ tumors. Clinical trial information: NCT00878709. [Table: see text]

ObjectiveThere is growing evidence from observational studies that lifestyle factors such as obesity, an unhealthy diet and lack of physical activity are associated with poor long-term outcome in women with breast cancer. The primary objective of the lifestyle modification part of the Simultaneous Study of Docetaxel Based Anthracycline Free Adjuvant Treatment Evaluation, as well as Life Style Intervention Strategies (SUCCESS C) Trial is to investigate the effect of an individualised lifestyle intervention programme aiming at moderate weight loss on disease-free survival in women with HER2/neu-negative breast cancer. Secondary objectives include the effect of the intervention on body weight, cardiovascular risk and quality of life.MethodsThe SUCCESS C Trial is an open-label, multicentre, randomised controlled phase III study using a 2×2 factorial design in women with newly diagnosed HER2/neu-negative intermediate-risk to high-risk breast cancer. The first randomisation served to compare disease-free survival in patients treated with two different chemotherapy regimens (3642 participants). The second randomisation served to compare disease-free survival in patients with a body mass index of 24–40 kg/m² (2292 participants) receiving either a telephone-based individualised lifestyle intervention programme for moderate weight loss or general recommendations for a healthy lifestyle for 2 years. Outcome analyses will be conducted after 5 years of follow-up.PerspectiveThis study will provide information on the efficacy and safety of a comprehensive lifestyle intervention programme on disease-free survival in a large cohort of women with breast cancer.

Aim: Adding pertuzumab to standard trastuzumab-based adjuvant therapy significantly improved invasive disease-free survival (IDFS) in the APHINITY trial. However, the magnitude of benefit was marginal in the overall population. Methods: We used GRADE (Grading of Recommendations Assessment, Development and Evaluation) analysis on data from APHINITY to build summary-of-findings tables to evaluate the efficacy, safety and quality of evidence of predefined clinical outcomes for the addition of pertuzumab to trastuzumab-based adjuvant therapy in patients with high-risk HER2-positive early breast cancer. Results: Pertuzumab significantly improved 3-year, event-free, absolute benefit in disease-free survival, IDFS and distant relapse-free interval (DFRI) in patients with node-positive or hormone receptor-negative disease. The analysis provides strength of evidence supporting the addition of pertuzumab in this patient population.

TPS597 Background: Triple negative breast cancer (TNBC), lack of ER, PR and HER2 expression, is known to have aggressive clinical features such as early recurrence, drug resistance, and frequent distant metastasis at the diagnosis. The most effective chemotherapy combinations used for early TNBC include anthracycline, taxanes, and/or platinum agents. Achieving a pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) provides important prognostic information and is considered as a surrogate endpoint in many clinical trials especially with TNBC. Patients with residual invasive disease after NAC have a high risk for early relapse and worse prognosis compared to those with pCR. Therefore, patients who did not get pCR could be better candidates for additional adjuvant treatment because their risk of recurrence would be higher than those with pCR. The CREATE-X (capecitabine for residual cancer as adjuvant therapy) trial howed that adjuvant capecitabine treatment improved 5-yr rate of disease free survival in TNBC subtype. A recent study indicated that immunosuppressive microenvironment had developed even in early stage of TNBC with increased T cells with a high exhaustion signature which are targets of immune modulating agents. Therefore, earlier cooperation of immune modulating drugs would be beneficial by generating a long-lasting anti-tumor immune response to micrometastatic disease, thus preventing disease relapse or recurrence. Methods: This study is a phase II, multicenter, randomized open label trial of atezolizumab (anti-PD-L1 antibody) and capecitabine compared with capecitabine in patients with TNBC who had residual disease after NAC. 284 patients will be enrolled from 15 sites in Korea with a primary objective to access the 5-yr invasive disease-free survival (IDFS) rate. Secondary objectives include 5-yr IDFS rate in PD-L1 positive population, distant relapse free survival (DRFS), overall survival (OS), and safety. Major inclusion and exclusion criteria are followings; 1) histologically confirmed TNBC, 2) received anthracycline and taxane based NAC followed by complete breast surgery, 3) residual disease after NAC must be ≥1cm in the greatest dimension, and/or have macroscopically positive lymph nodes. The study is open with 13 patients enrolled at the time of submission. Clinical trial information: NCT03756298 .

TPS602 Background: Women with triple-negative breast cancer (TNBC) having residual disease after neoadjuvant chemotherapy (NACT) as well as HR-positive/HER2-negative breast cancer (BC) with a CPS (clinical and post treatment pathological stage) +EG (estrogen receptor status and grade) score ≥ 3 or score 2 and nodal involvement after NACT (ypN+) are at high risk of recurrence. Sacituzumab govitecan is approved for the treatment of patients with metastatic TNBC who received at least two prior therapies for metastatic disease and has shown activity in heavily pretreated patients with metastatic HR-positive/HER2-negative BC. Therefore, sacituzumab govitecan may represent a new option against the resistant residual disease after standard NACT. Methods: SASCIA is a phase III, prospective, international, multi-center, randomized, open label, parallel group study in patients with HER2-negative BC with residual disease after NACT (NCT04595565). Eligible patients must have received taxane-based NACT for 16 weeks, including at least 6 weeks of a taxane. Patients should be at high risk of recurrence after treatment, defined as having centrally confirmed HER2-negative BC (IHC score 0-1 or FISH negative according to ASCO/CAP guideline) assessed preferably on tissue from postneoadjuvant residual invasive disease of the breast and either HR-negative (<1% positive stained cells), with any residual invasive disease > ypT1mi after NACT or HR-positive (≥1% positive stained cells), with a CPS+EG score ≥ 3 or CPS+EG score 2 and ypN+ using local ER and grade assessed on core biopsies taken before NACT. Radiotherapy should be delivered before the start of study treatment. Patients are randomized 1:1 to receive either sacituzumab govitecan 10 mg/kg body weight (days 1, 8 q3w for eight cycles) or treatment of physician´s choice (capecitabine 2000 mg/m² day 1-14 q21 or platinum-based chemotherapy i.e. carboplatin AUC 5 q3w or AUC 1.5 weekly for eight 3 weekly cycles or observation). Randomization is stratified by HR status (HR-positive vs negative) and nodal involvement after NACT (ypN+ vs ypN0). In patients with HR-positive BC, endocrine-based therapy will be administered according to local guidelines. The primary endpoint is invasive disease-free survival (iDFS). Secondary endpoints include comparison of overall survival (OS, key secondary endpoint), distant disease-free survival, locoregional recurrences-free interval, safety, compliance, iDFS and OS according to stratified and - predefined subgroups, patient reported outcome, and quality of life between treatment arms. As of February 2 2021, 7/1200 patients have been randomized in Germany. International study groups will join soon. Clinical trial information: NCT04595565.

Background Early studies of high-dose chemotherapy (HDC) for breast cancer were limited by small numbers and the lack of adequate control groups. The French PEGASE Group was founded to perform larger and properly randomized comparative studies of this approach. Methods The program was created to determine the effects of intensive chemotherapy for breast cancer. The seven PEGASE protocols addressed HDC as adjuvant therapy (01 and 06) and as treatment for inflammatory nonmetastatic disease (02, 05, and 07) and metastatic disease (03 and 04). Two of these protocols are ongoing. Results The PEGASE 01 adjuvant therapy trial showed that 3-year disease-free survival was significantly better in the HDC arm but overall survival was unchanged. The ongoing phase III 06 trial is studying a higher dosage regimen. The HDC trials for metastatic and inflammatory nonmetastatic disease are encouraging. Conclusions Many clinicians no longer subscribe to the concept of HDC for breast cancer. Overall outcomes from management of poor-risk breast cancer remain poor, however, and it is possible that some selected subgroups of patients may benefit from such an approach.

Purpose Capecitabine is an active drug in metastatic breast cancer (BC). GEICAM/2003-10 is an adjuvant trial to investigate the integration of capecitabine into a regimen of epirubicin and docetaxel for node-positive early BC. Patients and Methods Patients with operable node-positive BC (T1-3/N1-3) were eligible. After surgery, 1,384 patients were randomly assigned to receive epirubicin plus cyclophosphamide (EC; 90 and 600 mg/m2, respectively, × four cycles), followed by docetaxel (100 mg/m2 × four cycles; EC-T) or epirubicin plus docetaxel (ET; 90 and 75 mg/m2, respectively, × four cycles), followed by capecitabine (1,250 mg/m2 twice a day on days 1 to 14, × four cycles; ET-X); all regimens were given every 3 weeks. The primary end point was invasive disease-free survival. Secondary end points included safety (with an alopecia-specific study) and overall survival (OS). Results After a median follow-up of 6.6 years and 297 events, 86% of patients who received EC-T and 82% of those who received ET-X were invasive disease free at 5 years (hazard ratio, 1.30; 95% CI, 1.03 to 1.64; log-rank P = .03). The OS difference between arms was not statistically significant (hazard ratio, 1.13; 95% CI, 0.82 to 1.55; log-rank P = .46). The most frequent grade 3 to 4 adverse events in the EC-T versus ET-X arms were neutropenia (19% v 10%), with 7% febrile neutropenia across arms; fatigue (13% v 11%); diarrhea (3% v 11%); hand-foot syndrome (2% v 20%); mucositis (6% v 5%); vomiting (both, 5%); and myalgia (4.5% v 1%). Incomplete scalp hair recovery was more frequent in the EC-T than ET-X arm (30% v 14%), and patients who received EC-T wore wigs significantly longer than those who received ET-X (8.35 v 6.03 months). Conclusion Invasive disease-free survival, but not OS, was significantly superior for patients with node-positive early BC who received the adjuvant standard schedule EC-T than for those who received the experimental ET-X regimen. Toxicity profiles differed substantially across arms.

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.
