Objective: To determine the experience in a public institution (Hospital General de México) the relationship of KI67% and chemotherapy regimens about the progression free survival. Design: It is a retrospective study in which a total of 64 patients with a 36-month follow-up were evaluated, evaluating the percentage of KI67 and the chemotherapy regimens, which were AC+TXL vs CBP/TXL+AC. Results: A progression-free survival of 11.9 months was demonstrated in the patients who started with the CBP / TXL-based chemotherapy regimen and sequentially AC versus the 9.7 months achieved with the conventional ACX4 scheme and later add Carboplatin and Paclitaxel, and a Overall in both arms of 10.8 months, the patients who demonstrated the presence of a higher KI67 demonstrated increased progression-free survival compared to those with a low KI67, and with an unexpected surrogate that despite being few patients, those who showed higher levels of Progesterone had a lower survival compared to percentages of 5% or negative. Conclusions: Despite the fact that the first-line scheme for triple negative breast cancer was sequential and that the sample was only 64 patients, it was shown that adding carboplatin in the first line together with Paclitaxel in patients with high KI67 and without or with a minimal percentage of progresterone receptors increases Progression Free Survival.

The objective: was to evaluate the efficacy of the first line chemotherapy in patients with metastatic triple negative breast cancer (TNBC). Materials and methods. Open randomized study was performed including 122 patients with metastatic TNBC. The efficacy and safety of the first line chemotherapy of regimens АТ (n=59) – group 1, patients received doxorubicine 60 мг/м2 and paclitaxel 175 мг/м2 and ТР (n=63) – group 2, patients received paclitaxel 175 мг/м2 and carboplatin AUC 5 were evaluated. Results. The median duration of response was 9.5 months (4.5–13.25 months) in patients received AT regimen and 8.5 months (4.7–12.25 months), in TP regimen; no statistically significant differences were observed, р=0.836. The median progression free survival was 7 months (95% CI 5–26 months) in group 1 and 7.5 months (95% CI 6–35 months) in group 2, p=0.85. Both chemotherapy regimens (AT and TP) had mild or moderate toxicity profiles (grade 1 or 2 in most patients). No significant difference in gastrointestinal toxicity was observed. The incidence of grade 3–4 neutropenia was higher in patients of group 2 (TP regimen): 42.8% versus 27% (р<0.05). Conclusions. Both regimens of chemotherapy (AT and TP) are appropriate to use in the first line setting in patients with metastatic TNBC. Key words: metastatic triple negative breast cancer, chemotherapy, progression free survival, chemotherapy toxicity.

Aim: This study examined treatment patterns and effectiveness outcomes of patients with metastatic triple-negative breast cancer (mTNBC) from US community oncology centers. Materials & methods: Eligible patients were females, aged ≥18 years, diagnosed with mTNBC between 1 January 2010 and 31 January 2016. Kaplan–Meier and Cox regression methods were used. Results: Sample comprised 608 patients with average age of 57.5 years and 505/608 patients (83.1%) received systemic treatment. Overall survival (OS) from first-line treatment found that African–American patients had shorter OS than White (9.3 vs 13.7 months; hazard ratio: 1.35; p = 0.006). Conclusion: More than 15% of women with mTNBC were not treated, indicating a high unmet need. Overall prognosis remains poor, which highlights the opportunity for newer therapies to improve progression-free survival and OS.

<b><i>Background:</i></b> The addition of bevacizumab to chemotherapy conferred a modest progression-free survival (PFS) benefit in metastatic triple-negative breast cancer (mTNBC). However, no overall survival (OS) benefit has been reported. Also, its combination with carboplatin-cyclophosphamide (CC) has never been investigated. <b><i>Methods:</i></b> The Triple-B study is a multicenter, randomized phase IIb trial that aims to prospectively validate predictive biomarkers, including baseline plasma vascular endothelial growth factor receptor-2 (pVEGFR-2), for bevacizumab benefit. mTNBC patients were randomized between CC and paclitaxel (P) without or with bevacizumab (CC ± B or P ± B). Here we report on a preplanned safety and preliminary efficacy analysis after the first 12 patients had been treated with CC+B and on the predictive value of pVEGFR-2. <b><i>Results:</i></b> In 58 patients, the median follow-up was 22.1 months. Toxicity was manageable and consistent with what was known for each agent separately. There was a trend toward a prolonged PFS with bevacizumab compared to chemotherapy only (7.0 vs. 5.2 months; adjusted HR = 0.60; 95% CI 0.33–1.08; <i>p</i> = 0.09), but there was no effect on OS. In this small study, pVEGFR-2 concentration did not predict a bevacizumab PFS benefit. Both the intention-to-treat analysis and the per-protocol analysis did not yield a significant treatment-by-biomarker test for interaction (<i>p</i><sub>interaction</sub> = 0.69). <b><i>Conclusions:</i></b>CC and CC+B are safe first-line regimens for mTNBC and the side effects are consistent with those known for each individual agent. pVEGFR-2 concentration did not predict a bevacizumab PFS benefit.

Patients diagnosed with unresectable locally advanced Triple Negative Breast Cancer (TNBC) usually have poor outcome for its aggressive clinical behaviour. Atezolizumab plus nanoparticle albumin-bound (nab)-Paclitaxel prolonged progression-free survival (PFS) and overall survival (OS) among patients with unresectable locally advanced TNBC but its use is hampered by the lack of reliable predictors of tumor response. Seventy-seven consecutive patients with unresectable locally advanced TNBC treated with Atezolizumab plus nab-Paclitaxel were studied by blood draws at baseline, 28 days and 56 days after initiation of treatment. Exosomal PD-L1 mRNA in plasma was determined using Bio-Rad QX100 digital droplet PCR system and exoRNeasy kit and objective responses were defined following the RECIST criteria v.1.1. The study evaluates whether PD-L1 mRNA copies per ml in plasma-derived exosomes may predict response to anti-PD-L1 antibodies early in the course of therapy. Our data showed patients with unresectable locally advanced TNBC and higher levels of PD-L1 mRNA expression in plasma-derived exosomes at baseline demonstrated greater response to atezolizumab plus nab-paclitaxel. Furthermore, the levels of mRNA decreased with successful treatment while the copy number increased in patients experiencing disease progression following atezolizumab plus nab-paclitaxel. For the first time, our data showed the usefulness of assessment of exosomal PD-L1 as non-invasive real-time biopsy in patients diagnosed with TNBC suggesting exosomal PD-L1 is significantly associated with outcome and response to Atezolizumab plus nab-Paclitaxel.
