BACKGROUND: The standard treatment for patients with small, node-negative, human epidermal growth factor receptor type 2 (HER2)-positive breast cancer (BC) is still controversial. Our aim was to assess the prognostic role of tumour-infiltrating lymphocytes (TILs) in patients with stage pT1a-b HER2-positive BC. PATIENTS AND METHODS: Haematoxylin and eosin slides from node-negative, pT1a-b HER2-positive BC surgical specimens were retrieved from pathology archives to assess TILs and their association with outcome...

BACKGROUND: Triple-negative breast cancer (TNBC) lacks a standard targeted therapeutic strategy and is treated with conventional cytotoxic agents. Because of the sensitivity of TNBC to platinum compounds and the synergistic effect of bevacizumab with paclitaxel we investigated the efficacy and toxicity of weekly paclitaxel and carboplatin in combination with bevacizumab as first-line treatment in metastatic TNBC. PATIENTS AND METHODS: This phase II study followed the Simon's 2-stage optimal design...

Calcium ions (Ca(2+) ) act as second messengers in intracellular signaling. Ca(2+) pumps, channels, sensors, and calcium binding proteins, regulate the concentrations of intracellular Ca(2+) as a key regulator of important cellular processes such as gene expression, proliferation, differentiation, DNA repair, apoptosis, metastasis, and hormone secretion. Intracellular Ca(2+) also influences the functions of several organelles, that include: the endoplasmic reticulum, mitochondria, the Golgi, and cell membrane both in normal and breast cancer cells...

BACKGROUND: Patients who receive an abnormal cancer screening result require follow-up for diagnostic testing, but the time to follow-up varies across patients and practices. METHODS: We used a simulation study to estimate the change in lifetime screening benefits when time to follow-up for breast, cervical, and colorectal cancers was increased. Estimates were based on four independently developed microsimulation models that each simulated the life course of adults eligible for breast (women aged 50-74 years), cervical (women aged 21-65 years), or colorectal (adults aged 50-75 years) cancer screening...

PURPOSE: To guide early stage breast cancer patients to choose between breast conserving surgery (BCS) and mastectomy (MST) considering the predicted cosmetic result and quality of life (QoL). METHODS: A decision model was built to compare QoL after BCS and MST. Treatment could result in BCS with good cosmesis, BCS with poor cosmesis, MST only, and MST with breast reconstruction. QoL for these treatment outcomes were obtained from a previous study and the literature and translated into EuroQoL-5D derived utilities...

Background: Breast cancer is a leading cause of morbidity and deaths among women worldwide. In Tanzania there is no published data on human epidermal growth receptor-2 (HER2/neu) expression in breast carcinoma. Hormonal receptors and HER2/neu status reportedly influence post-mastectomy adjuvant therapy and predict treatment outcome and prognosis. Here we evaluate hormonal receptors and HER-2 status in biopsies of women with breast cancer at Muhimbili National Hospital (MNH). Methods: A cross-sectional study of female breast post-modified radical mastectomy (MRM)/incisional biopsies confirmed to be carcinoma at the Histopathology Unit (January-December 2013)...

Skeletal muscle loss, commonly known as sarcopenia, is highly prevalent and prognostic of adverse outcomes in oncology. However, there is limited information on adults with early breast cancer and examination of other skeletal muscle indices, despite the potential prognostic importance. This study characterizes and examines age-related changes in body composition of adults with early breast cancer and describes the creation of a novel integrated muscle measure. Female patients diagnosed with stage I-III breast cancer with abdominal computerized tomography (CT) scans within 12 weeks from diagnosis were identified from local tumor registry (N = 241)...

Tumor-infiltrating T cells play an important role in many cancers, and can improve prognosis and yield therapeutic targets. We characterized T cells infiltrating both breast cancer tumors and the surrounding normal breast tissue to identify T cells specific to each, as well as their abundance in peripheral blood. Using immune profiling of the T cell beta-chain repertoire in 16 patients with early-stage breast cancer, we show that the clonal structure of the tumor is significantly different from adjacent breast tissue, with the tumor containing ∼2...
