The GEICAM/2003-11_CIBOMA/2004-01 trial explored extended adjuvant capecitabine after completion of standard chemotherapy in patients with early TNBC. Eligible patients were those with operable, node-positive-or node negative with tumor 1 cm or greater-TNBC, with prior anthracycline- and/or taxane-containing chemotherapy. After central confirmation of TNBC status by immunohistochemistry, patients were randomly assigned to either capecitabine or observation. Stratification factors included institution, prior taxane-based therapy, involved axillary lymph nodes, and centrally determined phenotype (basal v nonbasal, according to cytokeratins 5/6 and/or epidermal growth factor receptor positivity by immunohistochemistry). The primary objective was to compare disease-free survival (DFS) between both arms. Eight hundred seventy-six patients were randomly assigned to capecitabine (n = 448) or observation (n = 428). Median age was 49 years, 55.9% were lymph node negative, 73.9% had a basal phenotype, and 67.5% received previous anthracyclines plus taxanes. Median length of follow-up was 7.3 years. DFS was not significantly prolonged with capecitabine versus observation [hazard ratio (HR), 0.82; 95% CI, 0.63 to 1.06; P =.136]. In a preplanned subgroup analysis, nonbasal patients seemed to derive benefit from the addition of capecitabine with a DFS HR of 0.53 versus 0.94 in those with basal phenotype (interaction test P =.0694) and an HR for overall survival of 0.42 versus 1.23 in basal phenotype (interaction test P =.0052). Tolerance of capecitabine was as expected, with 75.2% of patients completing the planned 8 cycles. This study failed to show a statistically significant increase in DFS by adding extended capecitabine to standard chemotherapy in patients with early TNBC. In a preplanned subset analysis, patients with nonbasal phenotype seemed to obtain benefit with capecitabine, although this will require additional validation

Neoadjuvant Treatment of Stage IIB/III Triple Negative Breast Cancer with Cyclophosphamide, Doxorubicin, and Cisplatin (CAP Regimen): A Single Arm, Single Center Phase II Study (GBECAM 2008/02)

BackgroundThe DNA damaging platinum salts have been explored in the treatment of triple negative breast cancer (TNBC) based on preclinical, and, more recently, clinical evidence of specific susceptibility of TNBC to these agents. Despite the increased toxicity, treatment intensification with polychemotherapy improves response and might be of interest in patients presenting with large primaries. In this trial, we aimed at exploring the efficacy and tolerability of the addition of cisplatin to standard anthracycline–cyclophosphamide backbone in patients with stage IIB/III TNBC.Patients and methodsThis is a single arm, single center, non-randomized, phase II trial of stage IIB/III TNBC. Patients received neoadjuvant chemotherapy with cisplatin (50 mg/m2) in combination with doxorubicin (50 mg/m2) and cyclophosphamide (500 mg/m2) every 21 days and for a total of six cycles (CAP). After surgery, adjuvant chemotherapy consisting of docetaxel (75 mg/m2) every 21 days was further provided for four cycles. Primary outcome was pathological complete response in the breast and axilla (pCR; ypT0ypN0). Secondary outcomes were safety, disease-free survival (DFS), and overall survival (OS).ResultsEight (19.5%) out of 41 patients reached a pCR and 35 (85.4%) had a clinical complete or partial response. After a median follow-up of 47.4 months (interquartile range 30.9–61.9), the proportion of patients free of recurrence or death at 3 years was of 51.8% [95% confidence interval (CI) 34.6–66.5%], while the proportion of patients alive at 3 years was of 55.5% (95% CI 37.8–70.1%). Patients with a pCR rate or family history of breast and/or ovarian cancer showed a numerical but statistically non-significant trend for improved DFS and OS. The majority of patients received six cycles of CAP (82.9%). The three most common grade ≥3 adverse events were nausea (16.3%), vomiting (14.0%), and neutropenia (9.3%). Febrile neutropenia occurred in three patients (7.0%).ConclusionCisplatin in association with doxorubicin and cyclophosphamide was associated with a pCR rate of 19.5% in a cohort of patients with predominantly stage III tumors. The tolerability profile of this combination poses clinical challenges to its general use in clinical practice.Unique Identifier NumberGBECAM 2008/02.NCT Identifier NumberNCT03304756

Association of ESR1 mutations and visceral metastasis in patients with estrogen receptor-positive advanced breast cancer from Brazil

Mutations in the ESR1 gene (ESR1m) are important mechanisms of resistance to endocrine therapy in estrogen receptor-positive advanced breast cancer and have been recognized as a prognostic and predictive biomarker as well as a potential therapeutic target. However, the prevalence of ESR1m in real-world patients has not been adequately described. (erefore, we sought to evaluate the prevalence of ESR1m in metastatic samples from Brazilian patients with estrogen receptor-positive (ER+) advanced breast cancer previously treated with endocrine therapy. (e presence of ESR1m was evaluated in formalin-fixed paraffinembedded (FFPE) breast cancer tissue using real-time quantitative polymerase chain reaction (RT-qPCR). Mutations in codons 380, 537, and 538 of the ESR1 gene were analyzed. Out of 77 breast cancer samples, 11 (14.3%) showed mutations in the ESR1 gene. ESR1m were detected in a variety of organs, and the D538G substitution was the most common mutation. In visceral metastasis, ESR1m were detected in 25% (8/32) of the samples, whereas in nonvisceral metastasis, ESR1m were detected in 6.7% (3/45) of the samples. (e odds of a sample with visceral metastasis having an ESR1 mutation is 4.66 times the odds of a sample of nonvisceral metastasis having an ESR1 mutation (95% CI: 1.13–19.27; p value � 0.0333). Our study indicates that the prevalence of ESR1m in samples from Brazilian patients with metastatic ER+ breast cancer is similar to that described in patients included in clinical trials. We observed an association of ESR1m with visceral metastasis
