Prognostic Factors of Survival among Women with Metastatic Breast Cancer and Impact of Primary or Secondary Nature of Disease on Survival: A French P…
2016
We aim to determine whether differences in survival exist between two populations of women with metastatic breast cancer (MBC) and to identify prognostic factors of survival after metastasis diagnosis. Data on women with MBC diagnosed between 2000 and 2011 were provided by the Cote d'Or Breast cancer registry. Survival rates and median overall survival (OS) after metastasis diagnosis were determined using the Kaplan–Meier method and prognostic factors were determined in a Cox proportional hazard model. Overall, 282 women with primary MBC and 340 with secondary MBC were included. A 2-year survival rate was significantly better in women with primary MBC (50.8% [95% CI: 47.8–53.8%] versus 44.5…
<p>Nab-paclitaxel in pretreated metastatic breast cancer: evaluation of activity, safety, and quality of life</p>
2019
Objective Metastatic breast cancer (MBC) is an incurable disease; the treatment of this disease prolongs survival, improving the quality of life (QoL) with a balance between efficacy and toxicity of the treatment. In recent years, treatment with nab-paclitaxel has improved the already known antitumor activity of conventional paclitaxel, in terms of increased efficacy and better tolerability. The aim of this study was to evaluate nab-paclitaxel in Italian patients with MBC. Methods We conducted a retrospective analysis of 90 patients with histologically confirmed diagnosis of MBC. To evaluate the efficacy of nab-paclitaxel, overall survival (OS), progression-free survival (PFS), and overall …
Baseline Splenic Volume as a Prognostic Biomarker of FOLFIRI Efficacy and a Surrogate Marker of MDSC Accumulation in Metastatic Colorectal Carcinoma
2020
Background: Predictive biomarkers of response to chemotherapy plus antiangiogenic for metastatic colorectal cancer (mCRC) are lacking. The objective of this study was to test the prognostic role of splenomegaly on baseline CT scan. Methods: This study is a sub-study of PRODIGE-9 study, which included 488 mCRC patients treated by 5-fluorouracil, leucovorin and irinotecan (FOLFIRI) and bevacizumab in first line. The association between splenic volume, and PFS and OS was evaluated by univariate and multivariable Cox analyses. The relation between circulating monocytic Myeloid derived suppressor cells (mMDSC) and splenomegaly was also determined. Results: Baseline splenic volume >
Abstract PD3-06: Neratinib + fulvestrant for HER2-mutant, HR-positive, metastatic breast cancer: Updated results from the phase 2 SUMMIT trial
2019
Abstract Background: HER2 mutations define a rare subset of metastatic breast cancer (MBC) with a unique mechanism of oncogenic addiction to HER2 signaling. Neratinib, an irreversible pan-HER tyrosine kinase inhibitor, has demonstrated single-agent clinical activity in HER2-mutant MBC. In HER2-mutant, HR+ MBC, neratinib + fulvestrant (N+F) appears synergistic vs single-agent neratinib, possibly due to more complete inhibition of bi-directional signaling between HER2 and estrogen receptors. Here we describe interim efficacy results of the expanded HER2-mutant, HR+ MBC cohort treated with N+F from SUMMIT (NCT01953926). Methods: HR+ MBC patients (pts) with HER2 mutations documented by local te…
Abstract P1-19-08: Neratinib + trastuzumab + fulvestrant for HER2-mutant, hormone receptor-positive, metastatic breast cancer: Updated results from t…
2020
Abstract Background: HER2 mutations define a subset of metastatic breast cancers (MBCs) with a unique mechanism of oncogenic addiction to HER2 signaling. Neratinib, an irreversible pan-HER tyrosine kinase inhibitor, has been shown to have encouraging clinical activity when combined with fulvestrant in HER2-mutant, hormone receptor-positive (HR+) MBC [Smyth et al. SABCS 2018]. Genomic analyses suggest that acquired resistance to neratinib may occur by the acquisition of additional HER2 alterations, which may amplify HER2 pathway signaling [Won et al. AACR 2019]. We therefore explored whether dual HER2-targeted therapy may improve clinical benefit in this setting. Here we describe initial res…
The McCAVE Trial: Vanucizumab plus mFOLFOX‐6 Versus Bevacizumab plus mFOLFOX‐6 in Patients with Previously Untreated Metastatic Colorectal Carcinoma …
2019
Abstract Background Bevacizumab, a VEGF‐A inhibitor, in combination with chemotherapy, has proven to increase progression‐free survival (PFS) and overall survival in multiple lines of therapy of metastatic colorectal cancer (mCRC). The angiogenic factor angiopoetin‐2 (Ang‐2) is associated with poor prognosis in many cancers, including mCRC. Preclinical models demonstrate improved activity when inhibiting both VEGF‐A and Ang‐2, suggesting that the dual VEGF‐A and Ang‐2 blocker vanucizumab (RO5520985 or RG‐7221) may improve clinical outcomes. This phase II trial evaluated the efficacy of vanucizumab plus modified (m)FOLFOX‐6 (folinic acid (leucovorin), fluorouracil (5‐FU) and oxaliplatin) ver…
Neoadjuvant eribulin mesylate following anthracycline and taxane in triple negative breast cancer: Results from the HOPE study
2019
BackgroundEribulin mesylate (E) is indicated for metastatic breast cancer patients previously treated with anthracycline and taxane. We argued that E could also benefit patients eligible for neoadjuvant chemotherapy.MethodsPatients with primary triple negative breast cancer ≥2 cm received doxorubicin 60 mg/m2 and paclitaxel 200 mg/m2 x 4 cycles (AT) followed by E 1.4 mg/m2 x 4 cycles. Primary endpoint was pathological complete response (pCR) rate; secondary and explorative endpoints included clinical/metabolic response rates and safety, and biomarker analysis, respectively. Using a two-stage Simon design, 43 patients were to be included provided that 4 of 13 patients had achieved pCR in the…
The prognostic relevance of HER2-positivity gain in metastatic breast cancer in the ChangeHER trial
2021
Breast cancer (BC) heterogeneity is composite in nature, with a wide variety of factors concurring to define several pathological entities, which differ by clinical presentation, pathologic features, therapy administered, and inherent outcomes1. Additional sources of breast cancer heterogeneity may raise during the disease course. In BC patients whose disease was initially diagnosed in the early stage and subsequently progressed with metastatic involvement of one single or multiple site/s, the molecular characteristics of metastatic lesions do not necessary mimic those of the disease initially diagnosed. A well-depicted molecular landscape is crucial for subtype definition, prognostic evalu…
Dose-Dense Chemotherapy in Metastatic Breast Cancer: Shortening the Time Interval for a Better Therapeutic Index
2015
Despite the advancement of targeted therapies in metastatic breast cancer, chemotherapy is still of pivotal importance. The concept of dose density is known to increase the efficacy of chemotherapy. In metastatic disease, preservation of the quality of life is equally important. Because of this, weekly regimens are a cornerstone in metastatic disease. Taxanes like paclitaxel or nab-paclitaxel as well as antracyclines are often used in palliative treatment. Further advances to increase dose density have led to the concept of daily metronomic schedules with oral chemotherapeutic drugs like cyclophosphamide, capecitabine, or vinorelbine. Metronomic chemotherapy affects tumor angiogenesis and a…
The Clinical Efficacy of Radium-223 for Bone Metastasis in Patients with Castration-Resistant Prostate Cancer: An Italian Clinical Experience.
2017
<b><i>Background/Aim:</i></b> Prostate cancer frequently causes bone metastases and skeletal events that impair quality of life (QoL) and survival. The alpha emitter radium-223 is a new drug that improves treatment in men with castration-resistant prostate cancer (CRPC) and bone metastases. Our aim was to evaluate the effectiveness of radium-223. <b><i>Subjects and Methods:</i></b> In this retrospective study we enrolled 48 subjects. Pain reduction, alkaline phosphatase (ALP), time to first symptomatic skeletal event, and QoL were the variables we evaluated. <b><i>Results:</i></b> Radium-223 was well tolerated, with a m…
