A logistic regression model predicting high axillary tumour burden in early breast cancer patients.

Purpose: As elective axillary dissection is loosing ground for early breast cancer (BC) patients both in terms of prognostic and therapeutic power, there is a growing interest in predicting patients with (nodal) high tumour burden (HTB), especially after a positive sentinel node biopsy (SNB) because they would really benefit from further axillary intervention either by complete lymph-node dissection or axillary radiation therapy.

Methods/patients: Based on an analysis of 1254 BC patients in whom complete axillary clearance was performed, we devised a logistic regression (LR) model to predict those with HTB, as defined by the presence of three or more involved nodes with macrometastasis. This was accomplished through prior selection of every variable associated with HTB at univariate analysis.

Role of axillary ultrasound, magnetic resonance imaging, and ultrasound-guided fine-needle aspiration biopsy in the preoperative triage of breast cancer patients.

Purpose: Roughly two-thirds of early breast cancer cases are associated with negative axillary nodes and do not benefit from axillary surgery at all. Accordingly, there is an ongoing search for non-surgical staging procedures to avoid lymph-node dissection or sentinel node biopsy (SNB). Non-invasive imaging techniques with very high sensitivity (Se) and negative predictive value (NPV) could eventually replace SNB.

Magnetic resonance imaging in the preoperative setting for breast cancer patients with undetected additional disease.

Objective: The last few years have witnessed a significant increase in the preoperative use of Magnetic Resonance Imaging (MRI) for staging purposes in breast cancer (BC) patients. Many studies have confirmed the improvement that MRI can provide in terms of diagnostic assessment, especially with regard to additional disease foci. In the present study, we address the advantages and disadvantages of MRI in the preoperative setting for BC patients.

Factors predictive of mortality in a cohort of women surgically treated for breast cancer from 1997 to 2014.

Objective: To determine whether previously reported factors predictive of breast cancer mortality are effectively linked with mortality, particularly breast-cancer-specific mortality.

Methods: In a prospective study, clinical, surgical, and follow-up data were assessed for consecutive patients with breast cancer who underwent surgery between 1997 and 2014 at two centers in Barcelona, Spain. Predictors of mortality were assessed by multivariate analysis.

The appropriate axillary procedure after a positive sentinel node in breast cancer patients: the "Hôpital Tenon" score revisited. A two-institution study.

Introduction: Until recently, completion ALND has been considered the standard of care after a positive SN in breast cancer patients. However, most patients will not display further axillary involvement. The Tenon score is a simple nomogram that can be used intraoperatively to avoid completion ALND in low-risk patients.

Comparative Long-term Study of a Large Series of Patients with Invasive Ductal Carcinoma and Invasive Lobular Carcinoma. Loco-Regional Recurrence, Metastasis, and Survival.

Our aim was to compare histologic and immunohistochemical features, surgical treatment and clinical course, including disease recurrence, distant metastases, and mortality between patients with invasive ductal carcinoma (IDC) or invasive lobular carcinoma (ILC). We included 1,745 patients operated for 1,789 breast tumors, with 1,639 IDC (1,600 patients) and 145 patients with ILC and 150 breast tumors. The median follow-up was 76 months.

Breast Cancer Patients Undergoing Sentinel Node Biopsy: Additional Axillary Tumor Burden as a Function of the Total Number of Excised Sentinel Nodes-A Multicenter Study.

Background: Recent studies have challenged the long-standing assumption that breast cancer prognosis is determined by lymph node regional status. We assessed locoregional relapse, distant metastases, and mortality alongside additional axillary disease in breast cancer patients undergoing sentinel node (SN) biopsy.

Patients And Methods: This prospective study assessed 1070 women with clinical T1-T2 invasive breast cancer with negative clinical/ultrasound axillae.

Comparison of Screened and Nonscreened Breast Cancer Patients in Relation to Age: A 2-Institution Study.

Introduction: Screening programs for breast cancer aim to allow early diagnosis, and thus reduce mortality. The aim of this study was to assess the effect of a population screening program in a sample of women aged between 50 and 69 years in terms of recurrence, metastasis, biological profiles, and survival, and to compare their results with those of women of a wider age range who did not participate on the screening program.

Patients And Methods: A prospective multicenter study in which 1821 patients with 1873 breast tumors who received surgery between 1999 and 2014 at MútuaTerrassa University Hospital and the Hospital of Terrassa in Barcelona were analyzed.

A study comparing two consecutive historical periods in breast cancer with a focus on surgical treatment, loco-regional recurrence, distant metastases and mortality.

Background And Aim: Recent introduction of breast units, mass-screening programmes (SP) and sentinel node biopsy (SNB) has impacted on the clinical care of breast cancer patients (BC), resulting in a significant increase of breast-conserving surgery with the goal of achieving completely free margins and good cosmetic outcome, along with significantly less axillary morbidity. In order to ascertain the combined impact of SP and SNB on BC patients, we have reviewed the primary therapeutic approach of patients diagnosed with invasive breast carcinoma in our centre, both before and after implementation of the two new procedures.

Methods: 1,942 patients operated for BC between 1997 and 2013 in two clinical centres.

Differential patterns of recurrence and specific survival between luminal A and luminal B breast cancer according to recent changes in the 2013 St Gallen immunohistochemical classification.

Introduction: In 2011, the St Gallen panel introduced several changes in breast cancer classification, thereby creating the luminal B Her2- subtype. In 2013, the panel also included Ki67 overexpression and PR <20 % as risk factors, while excluding GH3 in the absence of increased Ki67. We compared the classification of 2011 modified with the new 2013 St Gallen classification.

Mortality and recurrence patterns of breast cancer patients diagnosed under a screening programme versus comparable non-screened breast cancer patients from the same population: analytical survey from 2002 to 2012.

Breast cancer screening programmes seem to bring about significant benefits, including decreased mortality, although they may also have some drawbacks such as false-negative and false-positive results. This study aims to compare the clinical outcome of a group of patients undergoing a breast cancer screening programme with that of a synchronous non-screened group of patients matched for age and follow-up period. We studied basic characteristics of epidemiology, immunohistochemistry, loco-regional relapse, distant metastases, disease-free interval and overall and specific mortality.

Positive versus negative sentinel nodes in early breast cancer patients: axillary or loco-regional relapse and survival. A study spanning 2000-2012.

Sentinel Node Biopsy (SNB) is a minimally invasive alternative to elective axillary lymph node dissection (ALND) for nodal staging in early breast cancer. The present study was conducted to evaluate prognostic implications of a negative sentinel node (SN) versus a positive SN (followed by completion ALND) in a closely followed-up sample of early breast cancer patients. We studied 889 consecutive breast cancer patients operated for 908 primaries.

Differential survival and recurrence patterns of patients operated for breast cancer according to the new immunohistochemical classification: analytical survey from 1997 to 2012.

Breast cancer can no longer be considered only one condition. It should be regarded rather as a heterogeneous group of diseases with different molecular outlines. The aim of this study is to establish a correlation between immunohistochemical tumor sub-typing and surgical treatment, local recurrence rates, distant metastases, and cancer-specific mortality at 5 and 10 years.

Ondansetron and dexamethasone dose combinations for prophylaxis against postoperative nausea and vomiting.

Background: Patients at high risk of postoperative nausea and vomiting often receive more than one prophylactic antiemetic drug. In this study we sought to determine whether one or more of four dose combinations of dexamethasone and ondansetron was superior in efficacy.

Methods: In a randomized, double-blind trial of four dose combinations, women having day-surgical gynecologic laparoscopy received IV dexamethasone and ondansetron 4 + 4 mg (Group D4/O4, n = 154), 4 + 2 mg (Group D4/O2, n = 151), 2 + 4 mg (Group D2/O4, n = 154), or 2 + 2 mg (Group D2/O2, n = 155).
