BACKGROUND: Preclinical and clinical studies have reported that human epidermal growth factor receptor 2 (HER2) overexpression yields resistance to endocrine therapies. Here the prevalence and prognostic impact of HER2-positive circulating tumor cells (CTCs) were investigated retrospectively in metastatic breast cancer (MBC) patients with a HER2-negative primary tumor receiving endocrine therapy. Additionally, the prevalence and prognostic significance of HER2-positive CTCs were explored in a chemotherapy cohort, as well as the prognostic impact of the estrogen receptor (ER) CTC status in both cohorts...

Background.  Data from international settings suggest that isolates of Mycobacterium tuberculosis with rpoB mutations testing phenotypically susceptible to rifampin (RIF) may have clinical significance. We analyzed treatment outcomes of California patients with discordant molecular-phenotypic RIF results. Methods.  We included tuberculosis (TB) patients, during 2003-2013, whose specimens tested RIF susceptible phenotypically but had a rpoB mutation determined by pyrosequencing. Demographic data were abstracted from the California TB registry...

BACKGROUND: Replication of intervention research is reported infrequently, limiting what we know about external validity and generalisability. The Smoke Free Homes Program, a minimal intervention, increased home smoking bans by United Way 2-1-1 callers in randomised controlled trials in Atlanta, Georgia and North Carolina. OBJECTIVE: Test the programme's generalisability-external validity in a different context. METHODS: A randomised controlled trial (n=508) of English-speaking callers from smoking-discordant households (≥1 smoker and ≥1 non-smoker)...

BACKGROUND: Astrocytomas are the most common primary tumor of the central nervous system. The distinction between different tumor grades can be tested despite criteria given by the World Health Organization (WHO). Ki-67 is a potent biological marker used in grading of astrocytomas, which estimates growth of the neoplasm quantitatively and will help in predicting prognosis accurately. OBJECTIVES: The aim of this was to study the proliferative activity using Ki-67 immunostaining and to assess the relationship of Ki-67 staining with the histopathological grading of astrocytomas...

Tumor heterogeneity has been suggested based on clinical and pathological findings. Several clinical findings can be explained by tumor evolution during progression and metastasis. We herein report a case of metastatic breast cancer indicated tumor heterogeneity by clinical findings and a genomic analysis. A 64-year-old woman with advanced breast cancer was treated with primary chemotherapy, to which primary tumor responded. After a 6 month treatment pause, lung, liver, and skin metastases developed and her serum tumor markers were elevated...

INTRODUCTION: Although the use of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is increasing for epidermal growth factor receptor (EGFR) testing in lung cancer, the discordance rate in EGFR mutations between lymph node (LN) samples obtained by EBUS-TBNA and primary tumor (PT) is not well known. Thus, we compared the EGFR mutation status of LN samples obtained by EBUS-TBNA and PTs to estimate the efficacy of using EBUS-TBNA specimens for EGFR testing in advanced, non-squamous, non-small cell lung cancer (NSCLC)...

Since the advent of monoclonal antibodies against epidermal growth factor receptor (EGFR) in colorectal cancer therapy, the determination of RAS mutational status is needed for therapeutic decision-making. Most prevalent in colorectal cancer are KRAS exon 2 mutations (40% prevalence); lower prevalence is observed for KRAS exon 3 and 4 mutations (6%) and NRAS exon 2, 3, and 4 mutations (5%). The Idylla™ KRAS Mutation Test on the molecular diagnostics Idylla™ platform is a simple (<2 minutes hands-on time), highly reliable, and rapid (approximately 2 hours turnaround time) in vitro diagnostic sample-to-result solution...

MOTIVATION: Many forms of variations exist in the human genome including single nucleotide polymorphism, small insert/deletion (DEL) (indel) and structural variation (SV). Somatically acquired SV may regulate the expression of tumor-related genes and result in cell proliferation and uncontrolled growth, eventually inducing tumor formation. Virus integration with host genome sequence is a type of SV that causes the related gene instability and normal cells to transform into tumor cells...

OBJECTIVES: The incidence of lymphoproliferative disorders (LPDs) is increasing in sub-Saharan Africa (SSA) due to population growth, aging, and human immunodeficiency virus (HIV). Despite significant burden, resources for diagnosis and treatment of LPDs are limited, with little infrastructure to deliver modern pathology services. Diagnostic and therapeutic decisions are therefore frequently made without tissue confirmation, leading to high rates of misdiagnosis and inappropriate treatment...

BACKGROUND: Triple-negative breast cancer (TNBC) lacks estrogen, progesterone, and human epidermal growth factor receptor 2 (HER2)/neu receptors, and is aggressive and therapeutically challenging. Genetic ancestry testing is an emerging medical field. Mitochondrial DNA (mtDNA), which is distinct from nuclear DNA, is maternally inherited and allows for origin determination. Patients with TNBC tend to be younger and are more likely to be African American, making this an ideal disease for mtDNA exploration...

OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) offers an alternative to shunt treatment for infantile hydrocephalus. Diagnosing treatment failure is dependent on infantile hydrocephalus metrics, including head circumference, fontanel quality, and ventricle size. However, it is not clear to what degree these metrics should be expected to change after ETV/CPC. Using these clinical metrics, the authors present and analyze the decision making in cases of ETV/CPC failure. METHODS Infantile hydrocephalus metrics, including bulging fontanel, head circumference z-score, and frontal and occipital horn ratio (FOHR), were compared between ETV/CPC failures and successes...
