Relationship of pathological features and a 21 gene expression assay in younger versus older women with node-negative endocrine receptor-positive breast cancer.

Purpose: Determining the need for adjuvant chemotherapy in estrogen receptor (ER)+ disease can be influenced by pathological characteristics and gene expression assays [i.e., Oncotype Dx recurrence scores (RSs)].

A pilot study of durvalumab and tremelimumab and immunogenomic dynamics in metastatic breast cancer.

Immune checkpoint inhibitors produce modest responses in metastatic breast cancer, however, combination approaches may improve responses. A single arm pilot study was designed to determine the overall response rate (ORR) of durvalumab and tremelimumab, and evaluate immunogenomic dynamics in metastatic endocrine receptor (ER) positive or triple negative breast cancer (TNBC). Simon two-stage design indicated at least four responses from the first 18 patients were needed to proceed with the second stage.

A prospective evaluation of clinical and genetic predictors of weight changes in breast cancer survivors.

Background: Postdiagnosis weight gain in patients with breast cancer has been associated with increased cancer recurrence and mortality. This study was designed to identify risk factors for weight gain and create a predictive model to identify a high-risk population for targeted interventions.

Methods: The weight of 393 patients with breast cancer from the Northwestern Robert H.

BRCA 1/2 gene mutation and gastrointestinal stromal tumours: a potential association.

Mutations of the BRCA1/2 genes have been described in association with a number of malignancies including cancers of the breast, ovary, prostate and stomach, but have never been described in relation to gastrointestinal stromal tumours (GIST). We describe a patient with a BRCA2 8642del3insC mutation who developed prostate cancer, breast cancer and GIST. GIST has been shown to be associated with a number of malignancies, including some of the common BRCA1/2-related cancers, but it has never been associated with BRCA1/2 gene mutations.

Phase II neoadjuvant clinical trial of carboplatin and eribulin in women with triple negative early-stage breast cancer (NCT01372579).

The purpose of this study is to evaluate the efficacy and safety of neoadjuvant treatment with carboplatin and eribulin in patients with early-stage triple negative breast cancer (TNBC), and to explore biomarkers based on DNA and protein expression profiles as predictors of response. Patients with histologically confirmed early-stage TNBC received carboplatin AUC 6 iv every 21 days, and eribulin 1.4 mg/m(2) day 1 and day 8 every 21 days for four cycles.

Pilot neoadjuvant trial in HER2 positive breast cancer with combination of nab-paclitaxel and lapatinib.

Lapatinib, a dual kinase inhibitor against epidermal growth factor receptor (EGFR) and human epidermal receptor two (HER2) has shown efficacy in treating HER2 positive breast cancer. Nanoparticle albumin bound (nab) paclitaxel was developed to reduce toxicities from paclitaxel and improve its efficacy. Thirty patients with stage I-III HER2 positive breast cancer were treated in the neoadjuvant setting with lapatinib 1,000 mg/day and nab-paclitaxel 260 mg/m(2) every 3 weeks for four cycles.
