<h3>Importance</h3> A pathologic complete response (pCR; no invasive or in situ cancer) occurs 40% to 50% of patients with<i>HER2</i>-positive (<i>HER2</i>+) and triple-negative (TN) breast cancer. The need for surgery if percutaneous biopsy the after neoadjuvant chemotherapy (NCT) indicates pCR (hereinafter referred as pCR) has been questioned, appropriate management axilla such is unknown. <h3>Objective</h3> To identify among exceptional responders NCT with a low risk axillary metastases...

Talazoparib has demonstrated efficacy in patients with BRCA-positive metastatic breast cancer. This study evaluated the pathologic response of talazoparib alone for 6 months a known germline BRCA pathogenic variant (gBRCA-positive) and operable cancer.Eligibility included 1 cm or larger invasive tumor gBRCA-positive disease. Human epidermal growth factor receptor 2-positive tumors were excluded. Twenty underwent pretreatment biopsy, once per day oral (1 mg), followed by definitive surgery....

We investigated differences in smoking behaviors between US-and Mexican-born ever smokers and examined the influence of US culture on initiation.Participants were 5030 adults Mexican descent enrolled an ongoing population-based cohort Houston, Tex.More men than women reported current smoking; rates among US-born higher those women. Smoking earlier published Hispanics non-Hispanic Whites but similar to African Americans. Current lower for Hispanics, Whites, Older age, male gender, a level...

We counsel our triple-negative breast cancer (TNBC) patients that the risk of recurrence is highest in first 5 years after diagnosis. However, there are limited data with extended follow-up on frequency, characteristics, and predictors late events. queried MD Anderson Breast Cancer Management System database to identify stage I–III TNBC who were disease free at from The Kaplan–Meier method was used estimate yearly recurrence-free interval (RFI), survival (RFS), distant relapse-free (DRFS),...

The aim of this study was to compare clinical and pathological outcomes after neoadjuvant chemotherapy between oestrogen receptor (ER)-positive invasive pure lobular carcinoma (ILC) ductal (IDC). This analysis included 1895 patients (n=177 ILC; n=1718 IDC), with stage I–III breast cancer, who received chemotherapy. Clinical response rates, the frequency positive surgical margins rate breast-conserving surgery were compared. There a trend for fewer good responses in ILC compared IDC. Tumour...

Purpose Carrier prediction models estimate the probability that a person has BRCA mutation. We evaluated accuracy of BOADICEA model and compared its performance with other (BRCAPRO, Myriad I II, Couch, Manchester Scoring System). also studied effect extended family information on risk estimation using BOADICEA. Methods area under receiver operating characteristic curves generated from 472 families one member tested for mutations. calculated sensitivity, specificity, predictive values at an...

This study was undertaken to determine the feasibility of enrolling breast cancer patients on a single-agent-targeted therapy trial before neoadjuvant chemotherapy. Specifically, we evaluated talazoparib in harboring deleterious BRCA mutation (BRCA+). Patients with germline and ≥1 cm, HER2-negative primary tumors were eligible. Study participants underwent pretreatment biopsy, 2 months talazoparib, off-study core anthracycline, taxane-based chemotherapy ± carboplatin, followed by surgery....

In this study, we developed integrative, personalized prognostic models for breast cancer recurrence and overall survival (OS) that consider receptor subtypes, epidemiological data, quality of life (QoL), treatment.A total 15 314 women with stage I to III invasive primary treated at The University Texas MD Anderson Cancer Center between 1997 2012 were used generate by Cox regression analysis in a two-stage study. Model performance was assessed calculating the area under curve (AUC)...

Atypical femoral fractures (AFFs) are rare adverse events attributed to bisphosphonate (BP) use. Few cases of AFF in cancer have been described; the aim this study is identify incidence and risk factors for a large center. This retrospective was conducted at MD Anderson Cancer Center. The rate among BP users calculated from January 1, 2004 through December 31, 2013. control group (n = 51) included 2 or 3 patients on BPs matched age (≤1 year) gender. Logistic regression analysis used assess...

Abstract Background Delays in the initiation of therapy among patients with early stage breast cancer (BC) can negatively affect outcomes. Patients treated neoadjuvant systemic chemotherapy (NSC) usually display tumors high-risk features. Considering these characteristics and evidence supporting adverse outcomes associated delays adjuvant initiation, we sought to determine whether a delay NSC is overall survival (OS). Methods We identified diagnosed between January 1995 December 2015...

Abstract Background An increasing proportion of human epidermal growth receptor 2 (HER2) positive (HER2+) metastatic breast cancer (MBC) is diagnosed as de novo stage IV disease. We hypothesize that a subset these patients who achieve no evidence disease (NED) status after multimodality HER2-targeted treatments may have prolonged progression-free survival (PFS) and overall (OS). Materials Methods Patients with IV, HER2+ MBC (n = 483) between 1998 2015 were identified at two institutions...
