Validation of the AJCC prognostic stage for HER2-positive breast cancer in the ShortHER trial

2019

Abstract Background The 8th edition of the American Joint Committee on Cancer (AJCC) staging has introduced prognostic stage based on anatomic stage combined with biologic factors. We aimed to validate the prognostic stage in HER2-positive breast cancer patients enrolled in the ShortHER trial. Methods The ShortHER trial randomized 1253 HER2-positive patients to 9 weeks or 1 year of adjuvant trastuzumab combined with chemotherapy. Patients were classified according to the anatomic and the prognostic stage. Distant disease-free survival (DDFS) was calculated from randomization to distant relapse or death. Results A total of 1244 patients were included. Compared to anatomic stage, the prognost…

PANHER study: a 20-year treatment outcome analysis from a multicentre observational study of HER2-positive advanced breast cancer patients from the r…

2021

Background: The evolution of therapeutic landscape of human epidermal growth factor receptor-2 (HER2)-positive breast cancer (BC) has led to an unprecedented outcome improvement, even if the optimal sequence strategy is still debated. To address this issue and to provide a picture of the advancement of anti-HER2 treatments, we performed a large, multicenter, retrospective study of HER2-positive BC patients. Methods: The observational PANHER study included 1,328 HER2-positive advanced BC patients treated with HER2 blocking agents since June 2000 throughout July 2020. Endpoints of efficacy were progression-free survival (PFS) and overall survival (OS). Results: Patients who received a first-l…

Impact of molecular and histological subtype of breast cancer on 18FDG-PET/CT imaging: Knowledge gained from recent studies

2016

International audience; Over the past few years, several studies have focused attention on the impact of breast cancer (BC) histological subtype or BC phenotype, as defined by hormone receptors (HR) and HER2 status, on the results of FDG-PET/CT at staging, or during neoadjuvant chemotherapy (NAC). At staging, sclerotic bone metastases from invasive lobular carcinoma (ILC) demonstrated low or no FDG uptake in comparison to metastases from invasive ductal carcinoma (IDC). The CT component of PET/CT imaging should be carefully analyzed in the staging of ILC. In patients with triple negative or HER2-positive tumors, the proportion of extraskeletal metastases is high; this must be taken into acc…

Stage IV breast cancer: a population-based study about prognostic factors according to HER2 and HR status

2015

International audience; We aim to describe trends in net survival (NS) and to assess the prognostic factors among women with de novo metastatic breast cancer (MBC) according to human epidermal growth factor receptor 2 (HER2) and hormone receptor (HR) status. Data on women suffering from de novo MBC and diagnosed from 1998 to 2009 were provided by the Côte-d'Or breast cancer registry. NS was described using the Pohar Perme estimator and prognostic factors were investigated in a generalised linear model. We identified 232 patients (mean age = 64.7). Median NS was 29.2 months, 1- and 5-year NS were 76% and 26% respectively. The survival trend in patients with HER2-positive tumours who did not …

Is There Still a Role for Endocrine Therapy Alone in HR+/HER2- Advanced Breast Cancer Patients? Results from the Analysis of Two Data Sets of Patient…

2020

<b><i>Background:</i></b> Different studies suggest that fulvestrant 500 mg every 28 days (HD-FUL) could be an active treatment in HR+ advanced breast cancer (ABC) patients even treated with aromatase inhibitors in the adjuvant setting. The aim of this analysis is to describe the outcome of ABC patients treated with HD-FUL as first-line treatment in terms of median duration of treatment and the overall response rate in a real-world setting. <b><i>Methods:</i></b> For the purpose of the present analysis, we considered two data sets of HR+ ABC patients collected in Italy between 2012 and 2015 (EVA and GIM-13 AMBRA studies). <b><i>Res…

Evaluación del grado de conversión de los receptores HER2, RE y RPg entre el cáncer de mama primario y sus respectivas metástasis

2017

Introducción: Tradicionalmente, las decisiones terapéuticas tanto del cáncer de mama precoz como de los estadios avanzados se han basado en los marcadores predictivos del tumor primario, tales como el receptor de estrógeno (RE), el receptor de progesterona (RPg) y el receptor 2 del factor de crecimiento epidérmico humano (HER2), asumiendo que éstos permanecían inmutables a nivel de la recaída metastásica. Objetivos: El objetivo general de esta tesis era investigar si el estado de los receptores HER2, RE y RPg realmente puede cambiar durante la progresión del cáncer de mama y profundizar en las causas y en el impacto clínico de dichos cambios. El objetivo principal era determinar la tasa de …

"Omics" of HER2-positive breast cancer.

2013

HER2/neu amplification/overexpression is the only somatic mutation widely considered to be a marker of disease outcome and response to treatment in breast cancer. Pathologists have made large efforts to achieve accuracy in characterizing HER2/neu status. The introduction of transtuzumab contributed to development of additional measures to identify sensitive and resistant subclasses of HER2/neu-positive tumors. In this article, we describe the latest advances in HER2/neu status diagnostic assessment and the most relevant research emerging from ‘‘Omics’’ (genomics, epigenetics, transcriptomics, and proteomics) studies on HER2/neu-positive breast cancer. A large quantity of biomarkers from dif…
