Management and treatment of triple-negative breast cancer patients from the NEMESI study: An Italian experience
2011
Abstract Aims Triple-negative breast cancers (TNBCs) lack expression of oestrogen, progesterone, and Human Epidermal Growth Factor 2 receptors. The NEMESI study described current Italian treatment practices in patients with operable, early-stage breast cancer (EBC). Patients and methods Retrospective, observational study involving 63 Italian oncology centres. Eligible patients were aged ⩾18 years with EBC (stage I–II) who had undergone surgery, received ⩾1 cycle of adjuvant chemotherapy and/or adjuvant hormonal therapy and attended an oncology centre between 1 January 2008 and 30 June 2008. This subanalysis focused on patients with TNBC. Variables evaluated included: demographic data/clinic…
The EndoPredict score provides prognostic information on late distant metastases in ER+/HER2− breast cancer patients
2013
Background: ER þ/HER2 � breast cancers have a proclivity for late recurrence. A personalised estimate of relapse risk after 5 years of endocrine treatment can improve patient selection for extended hormonal therapy. Methods: A total of 1702 postmenopausal ER þ/HER2 � breast cancer patients from two adjuvant phase III trials (ABCSG6, ABCSG8) treated with 5 years of endocrine therapy participated in this study. The multigene test EndoPredict (EP) and the EPclin score (which combines EP with tumour size and nodal status) were predefined in independent training cohorts. All patients were retrospectively assigned to risk categories based on gene expression and on clinical parameters. The primary…
The natural history of breast carcinoma in patients withor = 10 metastatic axillary lymph nodes before and after the advent of adjuvant therapy: a mu…
2005
BACKGROUND The majority of patients with breast carcinoma with ≥ 10 metastatic axillary lymph nodes (ALNs) develop recurrent disease within 5 years from diagnosis. The purpose of the current study, performed retrospectively, was to characterize the natural history of this subset of patients, both before and after the advent of adjuvant anthracycline-based chemotherapy and tamoxifen. METHODS Retrospectively, patients with primary breast carcinoma (N = 882) with ≥ 10 metastatic ALNs, treated between 1954 and 1998, were selected from 3 institutions: The University of Texas M. D. Anderson Cancer Center (Houston, TX); the Institut Gustave Roussy (Villejuif, France); and Hospital Clinico Universi…
Breast-conserving surgeries in HER-positive breast cancer patients are performed too rarely in Poland
2020
Breast cancer is the most common cancer among women in Poland and worldwide; after lung cancer it is the second highest cause of death among females with malignancies. HER2 positive breast cancer occurs in ca.15–20% of all cases. More often than other subtypes, it affects younger patients and more often spreads metastasises to internal organs. The new drugs against the HER2 receptor significantly improve patients’ prognoses, regardless of the initial stage. The authors of the study involved 1503 patients with HER2 positive breast cancer from all stages (I–IV); 482 patients received preoperative systemic therapy (chemotherapy or hormonal therapy), 385 trastuzumab. Among the 1219 females qual…
Targeting breast cancer initiating cells: advances in breast cancer research and therapy
2014
Over the past 10 years there have been significant advances in our understanding of breast cancer and the important roles that breast cancer initiating cells (CICs) play in the development and resistance of breast cancer. Breast CICs endowed with self-renewing and tumor-initiating capacities are believed to be responsible for the relapses which often occur after various breast cancer therapies. In this review, we will summarize some of the key developments in breast CICs which will include discussion of some of the key genes implicated: estrogen receptor (. ER), HER2, BRCA1, TP53, PIK3CA, RB, P16INK1 and various miRs as well some drugs which are showing promise in targeting CICs. In additio…
The EndoPredict Gene-Expression Assay in Clinical Practice - Performance and Impact on Clinical Decisions
2013
The validated EndoPredict assay is a novel tool to predict the risk of metastases of patients with estrogen receptor positive, HER2 negative breast cancer treated with endocrine therapy alone. It has been designed to integrate genomic and clinical information and includes clinico-pathological factors such as tumor size and nodal status. The test is feasible in a decentral setting in molecular pathology laboratories. In this project, we investigated the performance of this test in clinical practice, and performed a retrospective evaluation of its impact on treatment decisions in breast cancer. During one year, EndoPredict assays from 167 patients could be successfully performed. For retrospe…
Systemic treatment of bone metastases in castration-resistant prostate cancer (CRPC): pre-clinical to clinical point of view
2015
Abstract Prostate cancer (PCa) is the most common cancer and the third most common cause of cancer related mortality in men in the United States. Hormonal therapy remains the most effective therapy for patients with advanced prostate cancer, inhibiting proliferation and inducing apoptosis in tumor cells. Unfortunately, after short-term remissions (18–24 months), surviving tumor cells recur with castrate resistant prostate cancer (CRPC) with inevitable progression, development of metastases mainly in bone, and death within 2–3 years in most men. Improved understanding of the molecular basis underlying bone-specific metastases and resistance to ADT or chemotherapy will facilitate the rational…
Tratamiento neoadyuvante del cáncer de mama operable
2006
Preoperative or neoadjuvant systemic treatment refers to either the first postdiagnosis systemic treatment that a patient receives or indicates that additional subsequent therapy is intended. Randomized controlled clinical trials have shown that preoperative systemic treatment offers the same disease free survival and overall survival benefits as does adjuvant systemic treatment. Neoadjuvant therapy has been found to increase the breast-conserving surgery rate. This therapy also allows to evaluate the primary tumor response to chemotherapy. Additionally, on the basis of the biologic characteristics of a tumor and differences in the response to systemic treatment, primary systemic treatment …
Association de radiothérapie externe et de curiethérapie pour les cancers de la prostate
2017
International audience; Brachytherapy as sole treatment is standard of care for D’Amico classification low-risk prostate cancer. For intermediate and high-risk patients, brachytherapy can be associated to external beam radiation therapy to better take into account the risk of extracapsular effraction and/or seminal vesicle involvement. Three randomized studies have shown that this association increases freedom from relapse survival compared to exclusive external beam radiation therapy. This benefit is not shown for overall survival. The addition of a hormonal therapy to this association is most likely mandatory for high-risk patients, and needs to be confirmed for intermediate risk patients…
From adjuvant to preventive breast cancer treatment: bridging the gap over troubled waters
2006
Recently, chemoprevention trials have demonstrated the efficacy of preventive medical treatment (PMT) in reducing breast cancer (BC) detection rates in at-risk affected and unaffected women selected according to clinical and/or familial risk criteria, particularly with the use of tamoxifen (TAM). Major concerns limiting the routine use of TAM are the questionable benefit/risk ratio and poor patient compliance, which justify the studies undertaken to determine the efficacy of aromatase inhibitors (AIs) with respect to TAM. Issues such as therapy duration, impact on survival, incidence of side-effects and which subsets benefit most from treatment, still remain unsolved. Therefore, only ER+ BC…
